## IRS notices

- [IRS Notice Lookup](https://www.nextleveltaxresolution.com/irs-notices): The hub for all 54 IRS notices and letters in this library, grouped by what the letter is actually about (you owe a balance, the IRS intends to take something, liens/levies/passport, payroll tax becoming personal, a return is missing, the IRS is questioning your return, payment plans). Each row carries an urgency level — time-sensitive (a right expires if you do nothing, e.g. a 30-day CDP hearing window or a 90-day Tax Court petition), act soon (nothing expires yet but options narrow), or informational (reports something that already happened). Twenty of the 54 carry a right that expires; thirty-three do not. Linked rows have a full guide behind them. Includes the notice-number location (top-right corner of page one, beginning CP/LT/"Letter"), the matched-pair twins table (individual vs. business variants under different numbers — CP161/CP14, CP259/CP59, Letter 3219/Letter 531, etc.), the Spanish-language 6xx mirror of the 5xx series (CP601=CP501, CP621=CP521), the fixed collection sequence (balance notice → reminders → intent to levy → Final Notice with the 30-day CDP right → enforcement), what the library deliberately leaves out (refund notices, adjustment confirmations, credit-eligibility letters), and a FAQ.

- [CP504 — Notice of Intent to Levy](https://www.nextleveltaxresolution.com/irs-notices/cp504): What a CP504 actually allows the IRS to take (state refund), what still requires a Final Notice (wages, bank), the 30-day timing, the Collection Appeals Program, and the critical exception when a Final Notice was already issued.
- [CP2501 — Underreporter Inquiry](https://www.nextleveltaxresolution.com/irs-notices/cp2501): The earliest notice in the IRS matching process, before a CP2000 proposes a figure. What the ordering is worth, how to respond on the enclosed form, the 30-day period, and what arrives (CP2000, then CP3219A) if left unanswered.
- [CP2000 — Notice of Proposed Adjustment](https://www.nextleveltaxresolution.com/irs-notices/cp2000): A proposed change from computer matching — not a bill. The two response periods (Tax Topic 652's 30/60 days vs. the date printed), the AUR program's "AVOID AUDITING RETURNS" instruction, the §6213(a) levy bar, the 6651(a)(3) 21-day late-payment start, and the CP3219A 90-day Tax Court window that follows if unresolved.
- [CP516 — Second Request for an Unfiled Return](https://www.nextleveltaxresolution.com/irs-notices/cp516): The IRS's second request for a return you haven't filed. It adds one sentence the first letter didn't have — "We may determine your tax for you" — and that sentence is the whole notice. No deadline printed, but the refund clock and the SFR process are both named.
- [CP162 — Partnership/S-Corp Penalty Notice](https://www.nextleveltaxresolution.com/irs-notices/cp162): One of five notices in a series (CP162, CP162A–E). The suffix decides which penalty and which relief route. The 2022 split, the wider-than-expected e-filing rule, the partner-count arithmetic, and Rev. Proc. 84-35 — which the IRS Office of Chief Counsel confirmed in 2019 is still alive.
- [CP501 — First Reminder After the Bill](https://www.nextleveltaxresolution.com/irs-notices/cp501): The IRS's first reminder after a CP14. Its text says a federal tax lien has already arisen (automatic, invisible) and names the IRS's intent to file a public Notice of Federal Tax Lien. The difference between the two is the whole page — plus the 30-day Form 9423 Collection Appeals Program window and the penalty-rate doubling that comes two letters later.
- [CP504B — Business Notice of Intent to Levy](https://www.nextleveltaxresolution.com/irs-notices/cp504b): The business version of the intent-to-levy notice. Its 30 days is the IRS's waiting period before it may levy — not a hearing window. Form 9423 (CAP) belongs here; Form 12153 (CDP) belongs to the CP297 that usually follows. The disqualified employment tax levy exception, the "only once per period" rule, the §6331(k) levy bar while a plan or offer is pending, and the §6334(a)(13) tools-of-trade protection that does not apply to incorporated businesses.
- [CP161 — Business Balance Due](https://www.nextleveltaxresolution.com/irs-notices/cp161): The business version of the CP14. It carries two dates — a balance-due date and an earlier date tied to a 5% failure-to-deposit penalty. The §6601(e)(3) 21-day interest window (10 business days over $100,000), the Publication 15 "payment with return" exception that is wider than most assume, and the trust fund track that runs separately behind it.
- [CP59 — Return Delinquency Notice](https://www.nextleveltaxresolution.com/irs-notices/cp59): The IRS has no record of a return it expected. No deadline printed, no penalty attached, no enforcement in it. The two clocks running opposite ways — IRC 6501(c)(3) "at any time" assessment vs. the three-year refund window under 6511 — the six-year figure as policy (Policy Statement 5-133) rather than law, Form 15103 for non-filers, and the 6651(c)(1) penalty coordination arithmetic.
- [CP14 — First Balance-Due Notice](https://www.nextleveltaxresolution.com/irs-notices/cp14): The IRS's first bill for a balance on a return you filed. The four itemized charges (failure-to-file, failure-to-pay, estimated-tax penalty, interest), the §6601(e)(3) 21-day interest window (10 business days over $100,000), the §6651(h) payment-plan rate halving to 0.25%, the §6651(c)(1) penalty coordination arithmetic most pages get wrong, and the §6651(d) rate-doubling ten days after a CP504.
- [CP136 — Payroll Deposit Schedule Notice](https://www.nextleveltaxresolution.com/irs-notices/cp136): Tells a Form 941 filer whether it is a monthly or semiweekly depositor for the coming year. Nothing on it expires — the obligation changes on 1 January whether or not you respond. The $50,000 four-quarter lookback (Notice 931), the zero-in-the-table diagnostic (a missing Form 941, not a quiet quarter), the $100,000 next-business-day rule that flips a monthly depositor to semiweekly for the rest of that year and all of the next, and the 2%–15% deposit-penalty ladder charged on every late payroll.
- [CP518 — Final Reminder (Individual or Business)](https://www.nextleveltaxresolution.com/irs-notices/cp518): The last reminder before the IRS computes the year itself. It still prints no deadline — and it is the last letter in the sequence that doesn't. Two versions under one code (SSN/Form 1040 vs. EIN/business form), the individual version textually identical to the CP516, the refund-expiry date printed only on the individual version, the business version's unnamed trust-fund exposure (Trust Fund Recovery Penalty via Letter 1153, 60/75 days), and IRC 6501(b)(3) — an IRS-prepared return does not start the limitation clock.
- [CP503 — Second Reminder](https://www.nextleveltaxresolution.com/irs-notices/cp503): The second reminder on an unpaid balance. The last quiet letter — it names a public Notice of Federal Tax Lien filing as the next step and quotes, in the IRS's own words, the §6651(d) penalty escalation to 1% a month that arrives ten days after the CP504. The three states of the late-payment rate (0.25% reduced / 0.5% standard / 1% doubled — a factor of four), the Collection Appeals Program (Form 9423) right published on the CP503 page, the distinction between a lien arising and a lien filing, and the four things only a transcript can tell you.
- [Form 668-A — Bank Levy](https://www.nextleveltaxresolution.com/irs-notices/form-668-a): The IRS bank levy — a one-time snapshot of what was in the account the moment the bank received it, held for 21 days under §6332(c) before remittance. The difference from a wage levy (Form 668-W, continuous; no exempt amount on a bank levy), the five mandatory §6343(a)(1) release grounds, the §6331(k) levy bar while a plan or offer is pending, the §6334 exempt categories, wrongful levy for joint/non-owned funds, and the Kentucky FIDM levy (KRS 131.672) with no hearing right.
- [LT11 — Final Notice of Intent to Levy](https://www.nextleveltaxresolution.com/irs-notices/lt11): The canonical Final Notice page. The 30-day Collection Due Process hearing window runs from the date on the letter (not receipt — 26 CFR 301.6330-1), Form 12153, the four labels (LT11 / Letter 1058 / CP90 / CP297), the §6330(c)(2)(B) exception that lets you argue the amount, the levy bar during a timely CDP request (§6330(f) exceptions), the suspension of the 10-year collection period as the cost, the equivalent hearing (one year, no levy protection, no Tax Court), the §6331(k) levy bar while a plan or offer is pending, the §6334 exempt categories including the principal-residence court-order rule, the §6330(d)(1) 30-day Tax Court petition window, and the §6330(e) 90-day collection-period tail.
- [CP3219A — Notice of Deficiency](https://www.nextleveltaxresolution.com/irs-notices/cp3219a): The 90-day Tax Court petition window — a filing deadline, not a reply deadline (§6213(a), 150 days if outside the US). "Your ticket to the Tax Court" without first paying (Taxpayer Advocate Service). The §6213(a) bar on assessment and levy while the notice runs or a petition is pending (jeopardy/termination exceptions), the printed-date-is-always-timely rule, the one instrument under several numbers (CP3219A / CP3219N / Letter 3219 / Letter 531 / Letter 3219B), the Form 5564 waiver and why its figure differs, the §6651(a)(3) late-payment penalty starting 21 days after notice and demand (not the original due date), the $60 filing fee and fee waiver, the $50,000 small-case track and its no-appeal finality, audit reconsideration as the route back (only while unpaid), and Kentucky's 180-day federal-adjustments report under KRS 141.211(2).
- [Letter 1058 — Final Notice (Revenue Officer)](https://www.nextleveltaxresolution.com/irs-notices/letter-1058): The same legal instrument as the LT11, differentiated entirely on the fact that a revenue officer issued it. The 30-day Collection Due Process hearing window (§6330, Form 12153), the two clocks (statutory vs. the officer's own deadline for a financial statement), what an assigned officer can do that the automated system cannot (more reach: in-person meetings, third-party contacts under §7602(c), enforcement; more latitude: non-template payment plans, hardship judgments), the §6331(k) levy bar that an officer does not switch off, the Taxpayer Advocate Service as the free option for genuine hardship, the end of most unannounced IRS visits in July 2023 (Letter 725-B), and Kentucky's shorter collection process with no hearing right (KRS 131.510, 131.110).
- [Form 668-W — Wage Levy](https://www.nextleveltaxresolution.com/irs-notices/form-668-w): The IRS wage levy — continuous, attaching to each paycheck until released (the opposite of the one-time bank levy, Form 668-A). The three-day deadline to return the Statement of Dependents and Filing Status (miss it and the exempt amount defaults to married filing separately with zero dependents — the lowest figure), the Publication 1494 exempt-amount tables (filing status × pay period × dependents, reissued every January), the §6343(a)(1) mandatory release grounds with the wages-must / bank-may hardship split, the §6331(k) levy bar while a plan or offer is pending, Form 668-D as the release document, the anti-retaliation rule at 15 U.S.C. §1674, and why the 25% garnishment cap does not apply to tax debt (KRS 427.010(3)(c); 15 U.S.C. §1673(b)(1)(C)).
- [CP71 — Annual Reminder](https://www.nextleveltaxresolution.com/irs-notices/cp71): The annual reminder the IRS is required to send on any open balance until the collection statute expires — off the escalation ladder, not a step in it. The printed date is a payment date, not a statutory deadline (nothing forfeited), the four named consequences (interest/penalties, refund offset, NFTL filing, levy subject to CDP), the "we'll assume you agree if we don't hear from you" sentence, the CP71 vs CP71C distinction (passport/FAST Act language only on the CP71C), the ten-year collection statute from assessment with each year running its own, the suspensions and extensions (pending IA, offer, CDP hearing, innocent spouse, bankruptcy, combat zone, foreign residence), and why counting ten years from the tax year rather than from assessment is the usual error.
- [CP63 — Refund Held Over an Unfiled Year](https://www.nextleveltaxresolution.com/irs-notices/cp63): The IRS holds a refund on one year because a return for another year is missing — offset in advance, not a bill. The absolute printed date (no standard period published) is when the IRS may begin computing the older year from third-party records (single/MFS, no deductions or credits), nothing has been assessed yet, and filing the missing return (or giving a valid reason for not filing) is what releases the hold. The two opposite clocks: unlimited time to assess an unfiled year vs. the three-year refund expiry under IRC 6511/6513(b)(1) (withheld tax treated as paid on the original due date), the CP63 vs CP88 distinction ("may" vs "will" determine), the CP2566 that follows if the year stays unfiled, and Kentucky's separate 60-day protest window (KRS 131.110) plus 25% cost-of-collection fee (KRS 131.440) on a state assessment.
- [CP207 — Missing Schedule B / Averaged FTD Penalty](https://www.nextleveltaxresolution.com/irs-notices/cp207): A request for a corrected Record of Federal Tax Liability (Schedule B on Form 941), not a bill — but doing nothing invents a deposit penalty out of nothing. Without a usable schedule the IRS averages the quarter's total liability evenly across the period (Publication 15, p.37), applies your real deposits against those invented dates in the order received, and penalizes whatever does not line up — so on-time deposits can read as late against liabilities the average invented. The 45-day published window (an instruction, not a statutory deadline; a late response is assessed first then reviewed, not lost). The five rejection reasons (incorrect, missing, illegible, negative entries, totals not tying), the 2%–10% averaged-penalty band (the 15% rung does not apply; only where liability ≥ $2,500), the Pub 15 deposit-penalty ladder (2/5/10/10/15%) and the fourth-rung discrepancy between the notice and Pub 15, the sequencing trap (no abatement without a correct ROFTL; reasonable-cause statement travels in the same envelope signed under penalty of perjury), the 90-day deposit-designation right under Rev. Proc. 2001-58, the CP207 vs CP207L distinction (same letter, three-word difference), and Kentucky's separate withholding track with no averaging rule.
- [Letter 566 — Audit by Mail (Read the Suffix)](https://www.nextleveltaxresolution.com/irs-notices/letter-566): The initial contact letter opening a correspondence examination — an audit conducted entirely by mail. The suffix decides which letter you hold: 566-S (a specific item), 566-E (wages, withholding and refundable credits), 566-B and 566-J (initial contact combined with the 30-day letter — the examination report is already enclosed and an Appeals window is running), and 2202B (a customized 566-S). The Taxpayer Advocate Service labels the combination letters "45 Day Combo" (30 or 45 days from the date on the letter — no single number governs). Selection "doesn't automatically mean something is wrong"; one of the two listed outcomes is the return accepted as filed. The §6213(a) bar on assessment/levy until a Notice of Deficiency runs (with the §6851/6852/6861, 6213(b)(1) and 6213(d) exceptions), the two conferences (informal with the manager vs. Appeals — the Appeals request must precede the response date), the escalation if no response (items disallowed → Letter 525, the 30-day letter → Letter 3219, the 90-day Notice of Deficiency), the source gap (no IRS "Understanding Letter 566" page exists — TAS, IRM 4.19.13.8 and Pub. 3498-A instead), and Kentucky's 180-day federal-adjustments report under KRS 141.211(2) with the six-year assessment period for a late/omitted report.
- [Letter 525 — The 30-Day Letter (Act)](https://www.nextleveltaxresolution.com/irs-notices/letter-525): The General 30-Day Letter — transmits Form 4549 (Report of Income Tax Examination Changes) and opens the window to request an Appeals conference. The tax code's own definition of "30-day letter" at §6603(d)(3)(B) turns on it being the first letter offering Appeals, not the day count (which is why IRM records Letter 5153 and Letter 1912 are "not a 30-day letter"). Generally 30 days from the date of the letter (the trigger is the date of the letter, not receipt), with "generally" doing real work (combination letters 30/45, Letter 5153 10, Letter 692 15). The two Appeals routes and the $25,000 threshold — and the discrepancy between the IRS web page (tax + penalty) and Publication 3498-A (tax + penalties + interest) on what counts toward it. The protest goes to the address in the letter, not to Appeals directly (sending it to Appeals "may prevent Appeals from considering your case"). The §6213(a) bar on assessment/levy and the §6213(d) waiver that the enclosed agreement form is. Why the examiner asks for a statute extension: IRM 4.10.8.12.1's internal timetable (240/365/395/210 days — case-management, not your deadlines), and the §6501(c)(4)(B) right to refuse or limit the extension to particular issues or a period that the IRS must tell you about. The §6603 cash deposit that stops interest (with the Pub 556 limits). What happens if you do nothing (Notice of Deficiency — Letter 3219 after a mail audit, Letter 531 after an in-person one, 90 days to petition the Tax Court), and Kentucky's 180-day federal-adjustments report under KRS 141.211(2) with the six-year assessment period for a late/omitted report.
- [CP220 / CP210 — Business Account Adjustment](https://www.nextleveltaxresolution.com/irs-notices/cp220): A notice reporting an adjustment the IRS has already made to a business account — from either an examination or ordinary data processing, two very different sources the notice presents identically. The three outcomes (balance due, overpayment, even balance — the notice title carries all three), the IRS's one-sentence published description ("We made change(s) for the tax year specified on the notice") and its own answer that finding out what changed means calling the number on the notice. The CP210 vs CP220 distinction (one shared IRS page, word-for-word identical IRM titles, the descriptive-sentence difference that is not a rule to plan around — a CP210 can leave you owing). No appeal right expires, but a printed payment date ties a permissive penalty-removal conversation to it ("Contact us by the due date of your payment ... we may be able to remove the penalty"), and the §6601(e)(3) 21-day / 10-business-day (≥$100,000) interest-free window for paying after notice and demand. The "Imputed Underpayment" flag that marks a BBA partnership-audit adjustment with its own elections and deadlines. The thinnest-sourced page in this section (no published sample notice exists — built from the IRS taxpayer page and IRM 21.3.1.7.29/.31), and Kentucky's separate state-notice track with its own protest window and cost-of-collection fee.
- [CP88 — Refund Held (IRS Will Compute)](https://www.nextleveltaxresolution.com/irs-notices/cp88): The near-twin of the CP63 — same refund hold pending an unfiled year, same fix, same consequence section — differing by one modal verb: a CP63 says the IRS may determine your tax for you and a CP88 says it will. The absolute printed file-by date (the IRS publishes no day count; nothing has been assessed yet on the missing year and no amount is stated), the two opposite clocks (unlimited IRS assessment time on an unfiled year vs. the three-year refund expiry under IRC 6511/6513(b)(1), withheld wage tax treated as paid on the original due date), the §6501(b)(3) rule that an IRS-prepared substitute return does not start your limitation clocks, the §6651 failure-to-file (5%/mo, cap 25%) and failure-to-pay (0.5%/mo, cap 25%) penalty coordination (combined 5% not 5.5%), the release route (file the return or give a valid reason for not filing — no form and no appeal at this stage), the CP63-vs-CP88 specimen-cycle caveat (CP88 absent from the current IRS past-due index; possibly superseded, no IRS statement), and Kentucky's separate 60-day written protest window (KRS 131.110) plus 25% cost-of-collection fee (KRS 131.440) on a state assessment — a genuine forfeiture the federal letter is not.
- [CP71C — Passport Warning (Seriously Delinquent Tax Debt)](https://www.nextleveltaxresolution.com/irs-notices/cp71c): The annual balance reminder that adds the passport certification warning under §7345 (FAST Act). The threshold is not the trigger — "seriously delinquent tax debt" is a three-part definition: (1) more than the inflation-adjusted figure ($66,000 for 2026) in legally enforceable unpaid federal tax including assessed penalties and interest, (2) a Notice of Federal Tax Lien filed with §6320 administrative remedies lapsed or exhausted, or a levy issued, and (3) no exception. Balance alone does not certify; requirement 2 is the hinge most people miss (a filed lien is a specific event with its own Letter 3172). Certification ≠ revocation — the State Department generally will not issue or renew a passport, while revoking one you hold is discretionary and separate. The two statutory exceptions at §7345(b)(2): (A) a debt paid timely under an installment agreement (§6159) or an accepted offer in compromise (§7122) — a pending offer is on the IRS's administrative list, not the statute; (B) collection suspended by a §6330 CDP hearing or a §6015 innocent spouse election. The IRS's further administrative non-certification list (CNC, pending IA/offer, identity theft) is practice, not statute. The online payment-plan ceiling is $50,000 — every reader of this page is above it, so the route is Form 9465 by mail/phone (800-829-1040) with a financial statement, $107 setup fee. The threshold moves every January so older notices print older figures. And Kentucky's parallel: no state passport-certification route found, but KRS 131.1817 reaches professional/occupational licenses and motor vehicle registration — with the same installment-agreement carve-out closing both exposures at once.
- [CP508C — Tax Debt Certified (Passport at Risk)](https://www.nextleveltaxresolution.com/irs-notices/cp508c): The notice that the IRS has already certified your tax debt to the State Department as seriously delinquent under §7345. Certification is not revocation — the IRS tells the State Department, which then makes its own decisions (the IRS's own verbs: a passport "may be revoked," an application or renewal "will be denied"). The two conditions for "seriously delinquent" (more than the inflation-adjusted $66,000 for 2026 in legally enforceable unpaid federal tax including penalties and interest, AND a filed Notice of Federal Tax Lien with §6320 administrative rights exhausted/lapsed or a levy issued) — balance alone certifies nobody. The three lists kept apart: (1) the two statutory exceptions at §7345(b)(2) — an installment agreement (§6159) or accepted offer in compromise (§7122), and a §6330 CDP hearing or §6015 innocent spouse request; (2) what the IRS says is not a seriously delinquent tax debt (child support, FBAR, DOJ settlement); (3) what the IRS says it will not certify as practice (CNC, pending IA/offer, identity theft, bankruptcy, disaster area, combat zone). The one action that does three jobs (excludes from certification, bars levy under §6331(k), resolves the debt). The §7345(e) Tax Court / district court remedy for an erroneous certification. The expedited 9–16 day decertification route (open passport application plus travel within 45 days or living abroad; the 90-day State Department hold on a filed application). The §6331(k)(3) jeopardy exception and §6402 refund-offset carve-out. And Kentucky's parallel: no state passport-certification route, but KRS 131.1817 reaches professional/occupational licenses and motor vehicle registration — with the same installment-agreement carve-out closing both exposures at once.
- [CP90 — Final Notice of Intent to Levy (Same as LT11)](https://www.nextleveltaxresolution.com/irs-notices/cp90): A deliberately short Decode-state disambiguation page — a CP90 is the same Final Notice of Intent to Levy as an LT11, a Letter 1058, and a CP297, with the same 30 days from the date on the letter and the same Form 12153. The code only tells you which part of the IRS issued it (campus / automated collection / revenue officer / business campus), not how serious your situation is — the one code that does change the answer is Letter 1058 (a person is assigned). Every code the Taxpayer Advocate Service lists as carrying a Collection Due Process hearing right, split into the two groups: group one (intend to levy — LT11, Letter 1058, CP90, CP297, CP177, CP77, Letter 4066) where the hearing comes first, and group two (already levied — CP90C, CP92, CP242, CP297A, CP297C, LT75, Letter 2439) where §6330(f) moves the hearing to a reasonable time after the levy (jeopardy, state-refund levy, disqualified employment tax levy, federal contractor levy). The Letter 3174 re-warning that is not a fresh right (26 CFR 301.6330-1 — one CDP notice per tax and period). The CDP-vs-equivalent-hearing comparison (levy protection, 10-year suspension, Tax Court route), the §6331(k) levy bar while a plan or offer is pending, the cost of a timely request (suspends the 10-year collection period), and the full version on the LT11 page. Kentucky has no state equivalent — its 60-day written protest (KRS 131.110) sits at the assessment stage, not the levy stage.
- [CP91 — Social Security Levy (Up to 15%)](https://www.nextleveltaxresolution.com/irs-notices/cp91): A notice of intent to levy up to 15% of Social Security benefits for unpaid federal tax — a continuing levy under §6331(h) that attaches to each payment until released or the balance is paid, capped at 15% (a ceiling, not a fixed amount), and a deduction rather than a suspension (the other 85% keeps arriving). The key distinction from the Final Notice family: a CP91 does not carry Collection Due Process hearing rights and does not include Form 12153 — it normally arrives after the LT11/Letter 1058/CP90 Final Notice, so the 30-day CDP window has usually closed. What remains is an equivalent hearing (one year from the Final Notice date — lesser in three ways: levy not prohibited, 10-year period not suspended, no Tax Court route) or a Collection Appeals Program request. The §6334(f) exemptions stripped for this levy — four things exempt from an ordinary levy (unemployment §6334(a)(4), workers' comp (a)(7), minimum wage (a)(9), certain public assistance (a)(11)) are expressly reachable up to 15%, while service-connected disability (a)(10) and child-support judgments (a)(8) are not. The §6343 must-release rule for economic hardship (wages "must" be released, bank accounts "may" be — the IRS's own distinction), the §6331(k) levy bar while a plan or offer is pending (with the §6402 refund-offset carve-out and the 10-year suspension price), the §6330(b)(2) one-CDP-hearing-per-period limit, and the ten-year collection-period question that on an old balance can make every other option irrelevant. The hardship mechanics (Form 433-F or 433-A, what "basic reasonable living expenses" is measured against, the three things CNC does not do — penalties accrue, lien may still file, debt not forgiven). The Taxpayer Advocate Service as a free in-IRS route for hardship. And Kentucky's note: the 15% cap is federal only — KRS 131.510(1) levies administratively with 10 days' certified-mail notice and no published percentage cap, and the KRS 427.010 25% garnishment restriction expressly does not apply to tax debt.
- [CP508R — Passport Bar Lifted (Certification Reversed)](https://www.nextleveltaxresolution.com/irs-notices/cp508r): The notice that the IRS has reversed your seriously delinquent debt certification and notified the State Department under §7345. A CP508R is not a passport — it removes the tax bar on your passport, it does not issue, renew or return one, and you still have to apply. The State Department "is no longer required to deny" your application and "cannot revoke your current passport because of your tax status" — but it may still deny an application for reasons unrelated to your tax debt. No deadline on you; nothing on this notice expires. The 30-day reversal (and the 9–16 day expedited route) were the IRS's side of the process and are behind you by the time this notice arrives; the State Department timeframe is not published. Reversal is not always resolution: the debt may be paid, expired (ten-year collection period ran out — a pending offer, CDP request, innocent spouse claim or bankruptcy may have extended it), or parked in a status that excludes it from certification only while a condition holds (an installment agreement being timely paid, an accepted offer in compromise, a timely-requested CDP hearing, a pending innocent spouse request) — and the notice looks identical in all three cases. Only the account transcript tells them apart. A missed payment on an installment agreement can put you back where you started, including on certification. The §7345(e) civil-action remedy for a certification that should never have happened. The 90-day State Department hold on an already-open application. And Kentucky's note: no state passport-certification route, but KRS 131.1817 license/registration hold does not clear itself when the federal side does — a separate written tax clearance is required.
- [CP60 — Misapplied Payment Reversed](https://www.nextleveltaxresolution.com/irs-notices/cp60): The one collection notice that describes an IRS action rather than a taxpayer one — the IRS reviewed your account, found it had misapplied one of your payments, and reversed it ("We reviewed your account and found that we misapplied payments totaling…"), leaving the balance higher by that amount. Nothing new has been assessed; no new tax determined; the date on the notice is a payment date, not a deadline that forfeits a right. The balance is a factual claim about your money that is checkable and occasionally wrong — the payment did not vanish but landed on one of four ordinary destinations: a different tax year (most common), a different tax type (individual vs payroll module), another taxpayer's account (transposed SSN/EIN), or nowhere at all (returned, rejected, never processed). The 0.5%/mo late-payment penalty and interest keep running while the balance stands. What to do: pull the account transcript for the year on the notice and the years either side (free, online), find the payment on your own side (amount, date, and the year/form you wrote on the memo line or payment screen), and match the two — the first two destinations are usually resolved by one phone call to the number on the notice. An account transcript reports postings as transaction codes against a module, not as "your payment went to 2021," so reading it is the whole job. If a payment plan was in place, check it survived the balance change — a plan calibrated to the old balance can default quietly and the 0.25% reduced penalty rate stops with it. The IRS makes no automatic correction: if the reversal was itself wrong, it stays wrong until someone identifies the payment and says so. And Kentucky's note: a payment sent to the wrong government (IRS vs Kentucky DOR) is two separate problems on two separate accounts — and the state's 60-day written protest window (KRS 131.110) plus the 25% cost-of-collection fee (KRS 131.440) make a payment sitting in the wrong place far more expensive on the state side while the clock runs.
- [CP080 / CP080B / CP80 — Credit on Account, No Return Filed](https://www.nextleveltaxresolution.com/irs-notices/credit-on-account-no-return-filed): The rarest good-news IRS letter — payments or credits are sitting on your account for a period the IRS has no return for ("We've credited payments and/or other credits to your tax account … However, we haven't received your tax return"), and the one deadline nobody can waive is printed on the paper notice but not on the IRS's web page: "If you don't file your return or contact us, you may lose this credit. The Internal Revenue Code sets strict time limits for refunding or transferring credits." Three codes (CP080, CP080B, CP80) carry this notice and the IRS's own routing between them is broken — the CP080 page redirects to CP080B, no CP80 page exists, and irs.gov/cp80 returns a 404 (the dead link printed on the CP80 specimen), so the page is named after the situation rather than one code. No deadline is printed; the limit is statutory — generally three years from the original due date of that year's return under IRC 6511, and because IRC 6513(b)(1) treats withheld wage tax as paid on the original due date and 6513(b)(2) does the same for estimated payments, the money was "paid" on a date that has already gone by. After three years IRC 6511(b)(2)(B) caps recovery at tax paid in the two years preceding the claim — so the credit falls outside the window and recovery goes to zero, permanently, with no discretion anywhere to change it. An unfiled period also blocks other things — the IRS's online payment-plan application requires all required returns filed. The two alternatives the notice itself offers: send a newly-signed copy if you already filed, or call to transfer the credit to another form/period/taxpayer number. VITA ($69k income limit, disabilities, limited-English) and TCE (age 60+) free prior-year filing help, where available. And Kentucky's note: separate state accounts and limitation periods, with the asymmetry reversed — here time takes money federally, but on the state side the 60-day KRS 131.110 written protest window and 25% KRS 131.440 cost-of-collection fee take the right to argue.
- [CP259 — Business Return Missing (Page 3 Has a "Not Required to File" Box)](https://www.nextleveltaxresolution.com/irs-notices/cp259): The business twin of the CP59 — the IRS has no record of a business return it expected, most often a Form 941, generated because the EIN's filing requirement does not switch itself off when the activity stops. The enclosed Response form carries five printed "not required to file" boxes (business ceased operations; no employees in the period; no employees and none expected going forward with a last-wages-paid date; wages reported on Form 943/944 instead; other reason) — and for a business with no wages in the period a signed box, not a return, is the answer. The one condition that changes it: if you made federal tax deposits or other payments/credits for that period, you must file a signed return showing the payments to get a refund — "We had no employees" and "there is no money sitting there" are different questions, and a deposit turns the box into a return. One notice is issued per form and per period, so several letters usually mean one underlying problem (a dormant company generates a stack from a single unanswered question). The notice prints a refund limit on its face: three years from the due date of the return, or two years from the date the tax was paid — it sits in the "if you are required to file" branch a reader who thinks they owe nothing will skip, and it is printed twice more on page 4 ("You must file a tax return in order to apply a carry forward credit even though you may not be required to file"). The third box ("no employees and doesn't expect to pay wages in the future") is the one that closes the requirement rather than answering it quarter by quarter — getting it wrong is how a business that shut in 2023 is still receiving CP259s in 2026. If nothing is filed and nothing is disputed, the IRS "may file a substitute return for you and charge penalty and interest" — a business substitute return is built from what other parties reported, allows nothing the business would have claimed, and (IRC 6501(b)(3)) does not start the assessment clock. An unfiled business period also blocks the arrangements a business would want — payment plans, penalty relief, lien withdrawal. And if the missing returns are payroll and the withheld deposits were never paid over, it can become a personal exposure (Letter 1153 / Trust Fund Recovery Penalty). Kentucky's note: separate withholding registration and delinquency process, and a closed business does not close itself with the Commonwealth — KRS 131.1817 reaches licenses and registrations.
- [Letter 531 — Notice of Deficiency (Same Clock as a CP3219A)](https://www.nextleveltaxresolution.com/irs-notices/letter-531): A statutory Notice of Deficiency (IRC §6212) issued after an in-person audit — the same instrument and the same 90-day Tax Court clock as a CP3219A, a Letter 3219 (audit by mail), a CP3219N (IRS-filed return), and a Letter 3219B (business underreporter, Form 1120/1041). The IRS publishes "Understanding your notice" pages for the CP-numbered versions and not for the lettered ones, which is why a Letter 531 is hard to find online — the page exists to resolve that. 90 days to file a petition with the United States Tax Court (150 if addressed outside the U.S.), and neither the IRS nor the Court can extend it; the petition goes to the Court (not the IRS), filed electronically by 11:59 p.m. Eastern on the last day, with weekend/DC-holiday roll-over. The printed last-date-to-petition is a floor (filing by it is always timely) and runs from mailing — a notice properly mailed to your last known address is effective whether or not you read it (§6212(b)(1)), which is why a Form 8822 change of address matters. The amount on the notice is jurisdictional (not everything is challengeable in Tax Court) and excludes interest, which arrives later. While the period runs and while a petition is pending, §6213(a) bars assessment and levy for this deficiency (with narrow §6851/6852/6861 jeopardy/termination exceptions); it does not protect balances already assessed for other years. Sending the IRS more information does not pause the clock. If missed, the deficiency is assessed and audit reconsideration is the route back — but only while the tax remains unpaid (paying closes that door). The $50,000 small-case election (deficiency including penalties, per §7463; Pub 3498-A counts tax, interest and penalties as of the petition date) trades appeal rights for a simplified track; the $60 filing fee is waivable on an inability-to-pay application; the Court publishes a petition kit and the DAWSON e-filing system. A CPA represents before the IRS and Appeals without limit, but a Tax Court case is conducted by the taxpayer or someone admitted to that Court — admission is separate from a CPA license. Kentucky's note: a finalized federal deficiency starts a 180-day Kentucky clock under KRS 141.211(2) to file a federal adjustments report and pay additional Kentucky tax, measured from the final determination date (last-signature date if waived, or the first day no federal adjustment remains finally determined); one year to assess on a timely report, six years if late/absent/understated.
- [Letter 692 — Additional Findings (Read the Suffix)](https://www.nextleveltaxresolution.com/irs-notices/letter-692): A Request for Consideration of Additional Findings — the letter an examiner sends after considering something you submitted during an examination. What it means depends on which of the two examination programs produced it, because the IRS runs office/field audits under IRM 4.10.8 and correspondence (mail) audits under IRM 4.19.13, and they use this letter differently. The suffix decides which family you are in: 692, 692-A (claim), 692-B (no-change with adjustments), and 692-K (bankruptcy) belong to office and field examinations; 692-M and 692-T belong to correspondence examinations (692-T being the secure-messaging version). In an office or field exam, IRM 4.10.8.12.9.1 uses Letter 692 in exactly two situations — where the additional information did not change the report, and where the corrected report reduces it with no new issues raised — so the proposed tax did not increase; a revised report that raises a new issue or increases the deficiency calls for a new 30-day letter instead (or the Letter 5153 route where the statute is short). In a mail exam, IRM 4.19.13 uses a 692-M to give "a response/determination on submitted documents," lists it as the "15-day letter with report," and a manually prepared Statutory Notice of Deficiency may be mailed no earlier than the 31st day following one — so on a mail audit this letter can be a step toward a 90-day letter rather than a sign the number held. The 15-day response period is an internal instruction to the examiner, not a statutory right; the date on your letter is what governs. "A new 30-day letter is not needed" — a Letter 692 does not open or restart an Appeals window; whether the original 30-day Appeals window from the earlier Letter 525 is still open is a question about your dates. A self-check: IRM 4.10.8 records that a Letter 692 "is signed by the examiner" while 30-day letters "must be signed by the group manager." Section 6213(a) bars assessment and levy while the matter is still a proposal; signing the revised report is the §6213(d) waiver that ends that protection and makes the balance collectible (with §6851/6852/6861, 6213(b)(1) exceptions). If the case closes unagreed, the route runs to a Notice of Deficiency — Letter 531 after an in-person audit, Letter 3219 after a mail audit, 90 days to petition the Tax Court. If the examination has already closed and a tax was assessed, audit reconsideration is the route back — but only while the tax remains unpaid (paying closes that door; Form 12661 or a written letter with supporting documents; 30-day IRS estimate, "potentially several months"; Appeals available on a denial). The hard part is reading a revised Form 4549 against the original line by line — the difference is in the explanations, not the totals. Kentucky's note: where the examination ends by signing an agreement (precisely what a Letter 692 solicits), KRS 141.211(1)(i)1.b sets the final determination date at "the date upon which the last party signed the agreement," starting the 180-day federal-adjustments-report clock under KRS 141.211(2); one year to assess on a timely report, six years if late/absent/understated.
- [Letter 725-B — A Revenue Officer Has Booked a Meeting](https://www.nextleveltaxresolution.com/irs-notices/letter-725-b): A revenue officer's appointment letter — naming a date, a time and a location (an IRS office, your business, or a telephone appointment) — and the letter that replaced the unannounced visit. Since July 2023 (IR-2023-133) the IRS ended most unannounced revenue officer visits and contacts by this letter instead, with narrow exceptions (service of summonses/subpoenas; sensitive enforcement involving assets at risk of being placed beyond reach — "less than a few hundred each year"). It is an appointment, not a summons, and the IRS's own first instruction is to call and reschedule: "Call the assigned revenue officer to confirm or reschedule the appointment. You may request a change to the location of the meeting to your residence or business" — and the meeting can be held over the telephone. The real change is that the account has left the automated system: a revenue officer is a person with discretion, enforcement tools, and their own deadlines. The consequences listed on the letter (collect balances, substitute return, reject/terminate an installment agreement, levy, seizure, lien) are real but not automatic — each requires its own steps (a levy needs a Final Notice of Intent to Levy and CDP hearing rights; a seizure needs approvals and sometimes a court). Two statutory rights decide how it goes: §7521(b)(2) lets you suspend any interview to consult a representative at any point — "regardless of whether the taxpayer may have answered one or more questions" (the last twelve words are the ones usually cut), and the manual allows a minimum of 10 business days plus a Form 9297; and §7521(c) means the IRS may not require a represented taxpayer to attend an in-person meeting alongside their representative absent a summons (it reaches in-person interviews, not telephone appointments). A second statute, §6304(a), governs collection contact — once a valid Form 2848 is on file, contact must go through the representative (IRM 5.1.10.7.2) — enforceable by a civil action under §7433. The summons carve-out is written into §7521(b)(2) itself, and §7521(d) takes criminal investigations out entirely. Three triggers put a case in front of a revenue officer — unfiled returns, an unpaid balance, or both where the balance is employment tax — and the third carries a question that is not about the business at all: whether the trust fund portion should be assessed against a person (Letter 1153 / Trust Fund Recovery Penalty). The recommendation the page makes plainly: if the case involves unpaid employment tax, get a representative on the file and send them to the meeting instead of going yourself — because the questions that decide personal liability sound like small talk, are asked once, and an unprepared honest answer cannot be taken back. Form 4180 cannot be obtained by the taxpayer and the manual instructs the officer not to show it. Kentucky's note: the Department of Revenue has its own field collection staff, its own protest windows and enforcement tools, and its reach includes action against professional and occupational licenses — a category the IRS does not have.
- [CP2566 / Letter 2566 — The IRS Figured Your Year for You](https://www.nextleveltaxresolution.com/irs-notices/cp2566): The IRS's own proposed calculation of tax for an unfiled year, built from income reported about you by third parties (W-2s, 1099s, broker statements) — the first letter in the non-filer sequence with a number on it, and the number is not yours. 30 days from the date of the letter (IRM 5.18.1.6.5 calls it the "30-Day Letter" and says it "gives the taxpayer 30 days to respond"; the specimen prints an absolute date, which governs). It is a proposal, not an assessment — nothing has been billed and filing your own return is still the straightforward option at this stage. The IRS's figure is computed at a filing status of single or married filing separately, with no exemptions, deductions, credits, dependents, or business expenses the IRS does not know about — the IRS itself says its amount "may be higher than what you would owe if you filed your own return," and the most common single omission on a self-employment year is business expenses (a 1099 reports gross receipts and nothing about what it cost to earn them, so receipts and profit become the same number). Two names for one document: the IRS publishes it as CP2566 (specimen header "Notice 2566"), the Internal Revenue Manual and practitioners call it Letter 2566, and there is no "Letter 2566" page or specimen on irs.gov. Missing the 30 days produces a statutory Notice of Deficiency (CP3219N, IRC §6212) carrying 90 days (150 if addressed outside the U.S.) to petition the United States Tax Court — and a trap that does not exist today: after a Notice of Deficiency, filing a return without also petitioning the Tax Court gives up the ability to contest the liability there, so the two decisions must be made together. A structural point that makes waiting worse than it looks: a return the IRS prepares under IRC 6020(b) is "prima facie good and sufficient for all legal purposes," but IRC 6501(b)(3) provides that an IRS-executed return "shall not start the running of the period of limitations on assessment and collection" — so an IRS-prepared return leaves the tax assessed and collectible with none of your own limitation periods started; filing your own return is what starts them. Penalties continue (failure to file 5%/month capped at 25%, failure to pay 0.5%/month capped at 25%, coordinated to 5% combined under §6651(c)(1)). The first step is pulling the wage and income transcript for the year and comparing it with the notice — that comparison tells you whether the computation is roughly right or badly wrong. Kentucky's note: a federal computation does not produce a Kentucky one, and a state assessment can arrive independently — its 60-day protest window (KRS 131.110, from the notice date not receipt, in writing) and 25% cost-of-collection fee (KRS 131.440(1)(a)1, triggered 60 days after the original notice date by departmental practice) are the harder of the two deadlines, because missing the federal 30 days costs simplicity while missing the state window costs the right to argue at all.
- [CP215 — Business Civil Penalty (Find Out Which One)](https://www.nextleveltaxresolution.com/irs-notices/cp215): A civil penalty notice assessed on a business account — a container, not a penalty, because the same CP215 number arrives for a dozen different charges under different Internal Revenue Code sections, and everything downstream (relief route, deadline, magnitude) depends on which one. The IRS's own text is one sentence: "We sent you this notice because we charged you a civil penalty." The notice names the form, the tax period, and the Code section — and that section is the field to find first. The common groups: §6698/6699 (late or incomplete partnership Form 1065 / S-corp Form 1120-S returns, charged per partner or shareholder per month — a small partnership filing late multiplies into a surprising number); §6721/6722 (information returns W-2s/1099s filed late, incorrectly, or not furnished, charged per return in increasing tiers with annual caps — volume is what makes these large); §6656 (failure to deposit payroll taxes on time or by the required method, tiered by lateness — the most common and most likely to recur); and §6038/6038A/6677 (foreign-related information reporting — Forms 5471, 5472, 3520, 3520-A — a different order of magnitude entirely, charged per form per period, continuing after notice, with its own Appeals treatment). Dollar amounts for the first three groups are deliberately not published here because they are inflation-adjusted annually by revenue procedure and industry content routinely mixes years — the figure on your own notice is the correct one for your year. Whether filing the missing item today reduces the penalty is the highest-value question and is answerable from the Code section alone (for per-month and tiered penalties it frequently does). The audience point: CP215 is a business-account notice (IRM assigns it to the Business Master File, MFT 13) even though the IRS serves its page under /individuals/; the individual counterpart is CP15 (MFT 55). Assessable penalties like these bypass deficiency procedures — there is no 30-day letter, no Notice of Deficiency, and no route to the Tax Court before paying; the IRS assesses first and relief runs through abatement requests and post-assessment Appeals, so "wait for the formal letter" is a plan built on a letter that is not coming (this is the formal letter). The international information-return penalties are the exception and carry their own post-assessment Appeals timing worth establishing rather than assuming. The notice prints a payment date on which interest turns on. Relief routes are not mutually exclusive — First Time Abate (for eligible penalties with a clean three-year history, still must be requested; the IRS's new Automatic Exemption from Penalty, IR-2026-83 July 2026, begins with tax year 2025 returns and does not fully replace FTA until returns due on or after 1 January 2027), reasonable cause (rests on contemporaneous facts — dates, who was responsible, what records exist — which get worse with time), and statutory exceptions can apply to different penalties on the same notice, and using the wrong one first can spend an argument you would rather have kept; that sequencing is most of the skill in penalty work. If nothing is done the balance enters the business collection sequence (CP161, then lien and levy). Kentucky's note: the state assesses its own penalties on its own schedule, and responsible individuals can be held personally liable for sales tax collected and not remitted and for withholding on a basis that does not require the willfulness the federal Trust Fund Recovery Penalty turns on — a lower bar — plus a 25% cost-of-collection fee (KRS 131.440(1)(a)1, triggered 60 days after the original notice date by departmental practice) with no federal analogue.
- [CP92 — The IRS Took Your State Refund (and a Right Just Opened)](https://www.nextleveltaxresolution.com/irs-notices/cp92): Notice that the IRS has already levied your state tax refund, together with your right to a Collection Due Process hearing — "We levied your state tax refund for unpaid taxes and are informing you of your right to a Collection Due Process hearing." This is the one levy the law lets the IRS make without offering a hearing first: §6330(a) requires a pre-levy notice with hearing rights at least 30 days before any levy, but §6330(f)(2) carves out "a levy on a State to collect a Federal tax liability from a State tax refund" (alongside jeopardy, disqualified employment tax, and federal contractor levies). The carve-out delays the hearing; it does not remove it — the same subsection entitles you to one "within a reasonable period of time after the levy," and the CP92 is the delivery of it. 30 days from the date printed on the notice to request the hearing on Form 12153 (counted from the date on the letter, not receipt; a notice properly sent to your last known address starts the clock). A hearing is unlikely to bring the refund back — it examines whether collection going forward is appropriate and whether a less intrusive alternative would work, not whether to unwind a levy already satisfied; the one situation where it can be about the money is where the IRS assessed the year without you (a Substitute for Return or a notice sent to an old address), under §6330(c)(2)(B). What a timely request genuinely buys: per Pub 1660, levy action "is not permitted for the subject tax and periods during the 30 days after the levy notice and during the timely requested CDP hearing process" — it stops the wage levy, the bank levy and the lien. The one thing it does not stop is another state-refund levy for the same tax and period, which the regulation puts outside the suspension. The cost: a timely request suspends the 10-year collection period until Appeals' determination becomes final — a good trade for most, a deliberate one if the balance is old (§6343 requires release where the liability is "unenforceable by reason of lapse of time," and requesting a hearing pauses that clock). If the 30 days pass, an equivalent hearing is available for a year from the levy-notice date but without the levy bar, the collection-period suspension, or Tax Court review. A CP242 is the same notice under a different number ("We garnished your state tax refund to pay your federal taxes"), same rights, same Form 12153. A refund offset (Treasury Offset Program, §6402) is a different thing — it applies a refund to a debt before it reaches you, requires no Final Notice, and carries no CDP right at all; the paperwork tells you which you had. A pending installment agreement or offer bars further levy under §6331(k) (from the date the IRS accepts the offer for processing; it bars levy not lien, and it suspends the 10-year period) — and the two are not alternatives; you can do both. Only one CDP hearing is allowed per taxable period (§6330(b)(2)). After Appeals decides against you, §6330(d)(1) gives 30 days from the determination to petition the Tax Court — a second deadline that runs from a different document. Kentucky's note: KRS 131.560 has the state satisfy its own undisputed delinquent tax liability out of an income tax refund before transmitting any balance to a claimant agency, so the refund the IRS levied may have been smaller than expected before the IRS reached it; a 25% cost-of-collection fee under KRS 131.440 (scope "for purposes of the program described in KRS 131.400(3)," 60-day trigger by departmental practice, waivable for reasonable cause under subsection (2)); and an asymmetry — where a third-party agency's debt is claimed against your refund, KRS 131.570(1) requires written notice and a 30-day hearing right, but Kentucky's own tax liability is satisfied first and carries no corresponding notice-and-hearing right.
- [CP297 — The Business Final Notice, and Your 30 Days](https://www.nextleveltaxresolution.com/irs-notices/cp297): The Final Notice of Intent to Levy issued on a business account — the business counterpart of a CP90, with the same 30 days from the date on the notice, the same Form 12153, and the same Collection Due Process hearing rights under §6330. Its printed heading reads "Intent to seize your assets and notice of your right to a hearing," and the Taxpayer Advocate Service lists it alongside CP90, LT11 and Letter 1058 (CP90 = individual account, CP297 = business account, LT11 = automated collection system, Letter 1058 = assigned revenue officer — administrative differences, identical rights). 30 days from the date printed on the notice (26 CFR 301.6330-1 runs it from the day after the date of the notice; actual receipt is not a prerequisite; Pub 1660: "During the 30-day period from the date of the notice, you may request a hearing with Appeals"). While a timely request is pending, levy action is not permitted for that tax and period (narrow exceptions), and the 10-year collection period is suspended until Appeals' determination becomes final or the request is withdrawn in writing — a real cost on a business account where several periods may run separate clocks. If the 30 days pass, an equivalent hearing is available for a year but without the levy bar, the suspension, or Tax Court review. What the IRS can reach on a business: bank accounts (the bank freezes funds and holds them 21 days before remitting — a genuine window), accounts receivable (a levy served on your customers — the commercial damage usually exceeds the amount collected), wages and commissions (continuous once attached), business assets (equipment, vehicles, property), and state tax refunds (taken without a further letter under the §6330(f) carve-out). The receivables levy is the one to plan around — it is a communication to your customers that outlasts the tax problem. The question this notice does not ask: if any part of the balance is payroll tax, the trust fund portion can be assessed personally against individuals the IRS determines were responsible and willful — a separate process (Letter 1153 / Trust Fund Recovery Penalty) with its own letter and protest window that survives the entity and follows people to their own returns; closing the business does not close it. A pending installment agreement or offer bars levy under §6331(k) (from acceptance for processing; bars levy not lien; §6331(k)(3) borrows the §6331(i)(3) jeopardy exception and does not stop a federal refund offset under §6402). CP297A and CP297C are the post-levy versions (printed heading "Notice of seizure and notice of your right to a hearing") — CP297A follows a disqualified employment tax levy, CP297C a federal contractor levy; §6330(f)(3) excepts a disqualified employment tax levy from the pre-levy hearing, but §6330(h)(1) defines it narrowly (a prior CDP hearing request on employment tax within two years — not simply having payroll tax in the balance). §6343 release grounds (paid, expired, helps you pay, installment agreement, economic hardship, property worth more than the debt); §6343(d) return of property already taken (premature or procedural failure). §6334 exemptions: books and tools of a trade up to an annually adjusted amount, and a procedural protection for property used in a trade or business — but §6334(a)(13)(B)(ii) covers property "of an individual taxpayer," so a sole proprietor has it and an incorporated business or LLC does not. A principal residence is exempt absent written judicial approval. §6330(d)(1) gives 30 days from Appeals' determination to petition the Tax Court; only one CDP hearing per taxable period under §6330(b)(2). Kentucky's note: DOR can levy administratively without a court judgment once an assessment is final and tax is unpaid 30 days after demand, with a 10-day written notice floor under KRS 131.510(1) (vs. the federal 30-day floor under §6331(d)); KRS 131.1817 reaches professional/occupational licenses, attorney licenses, and vehicle registration (including failure to file within 90 days of the due date after department contact, regardless of balance); and there is no state analogue to the CDP hearing right — Kentucky's review is a 60-day written protest at the assessment stage (KRS 131.110) with no second door.
- [Federal Tax Lien Release — Publication 1450](https://www.nextleveltaxresolution.com/irs-notices/federal-tax-lien-release): How to get a federal tax lien released after you've paid. The 30-day deadline runs against the IRS (§6325(a)(1)), guaranteed funds get the certificate issued immediately, "legally unenforceable" is the second ground, release vs. withdrawal vs. discharge vs. subordination, and §7432 when the IRS fails to release.
- [Letter 903 — What the Employment Tax Warning Actually Means](https://www.nextleveltaxresolution.com/irs-notices/letter-903): A warning a revenue officer issues to an employer whose federal employment taxes have not been deposited — titled "You Haven't Deposited Federal Employment Taxes" — alerting the taxpayer to IRC §7402(a), which gives a federal district court jurisdiction to grant civil injunctions under Title 26 and Title 18 (IRM 5.7.2, revised 22 May 2025). It is not a bill and does not assess anything; it is a formal notification that the situation has been recognized as an employment tax problem rather than a balance, and it is a record so the government can show the employer was told if it ever seeks an injunction. The sentence people find and misread: "Issuance of Letter 903 is required before a taxpayer can be recommended for civil injunction or criminal prosecution" — that is a prerequisite the IRS must satisfy (a gate it walks through), not a prediction that a referral is coming; employment tax cases are common, injunction/prosecution referrals are rare, and the two numbers are not similar. The manual says these procedures are for "egregious cases of noncompliance when all available collection procedures have been exhausted, are unproductive or would be futile to stop or reduce trust fund pyramiding" — a late letter, not a routine one. No deadline is printed on the letter and none is published, but check the envelope: the manual requires Letter 903 to be hand-delivered with Notice 931 (Deposit Requirements for Employment Taxes — the deposit schedules, four-quarter lookback, $2,500 rule, $100,000 next-day rule), and IRM 5.7.2.2 contemplates issuing it "along with Letter 1058 during initial contact" where the taxpayer is a repeater with no assets — a Letter 1058 carries a hard 30-day clock, and if one is enclosed that clock is the thing with a date on it. The clock that actually matters is the current quarter: IRM 5.7.8.4 defines a pyramiding taxpayer as in business, not current with FTDs, with two or more trust fund modules in Field Collection, and states "Pyramiding must be stopped immediately" — becoming current going forward is the one fact the business can change today. What happens if you do nothing: prompt assessment, assessment under IRC 6020(b) (an IRS-prepared return that does not start the limitation period on assessment — only your own filed return does, IRC §6501(b)(3)), and possible civil or criminal referral (a recommendation to DOJ, not a decision by the IRS and not a conviction). Separately and more likely: the trust fund portion (withheld income tax plus the employee's half of FICA, nothing else) can be assessed against individuals personally on its own track with its own letter (Letter 1153) and its own 60 days. The thing most published guidance gets wrong: IRM 5.7.2.1.1 (dated 8 February 2021) says Form 941-M monthly filing and special deposit procedures are no longer required before the next collection action, though IRC 7215 remains on the books — guidance describing monthly filing as the next step is five years out of date, and the step that used to sit between this letter and the next collection action is gone. The deposit penalty ladder (Pub 15, 2026, p.36): 2% for 1–5 days late, 5% for 6–15, 10% for 16+, 10% for an amount paid directly or with the return instead of deposited, 15% for amounts still unpaid more than 10 days after the IRS's first notice — the fourth rung is the trap (catching up by check with the 941 is itself a 10% charge). Kentucky's note: state withholding is frequently short in the same quarters, and the Commonwealth's enforcement includes action against licenses and registrations with no federal equivalent that can stop trading faster than anything in this letter.
- [CP22A — The Bill for a Change You Probably Asked For](https://www.nextleveltaxresolution.com/irs-notices/cp22a): A balance-due notice reporting an adjustment the IRS made to your return — and in the ordinary case the change is one the taxpayer set in motion (an amended Form 1040-X, an answer to an earlier notice, a correction requested, or information supplied by a preparer), so the first question is not whether the IRS is entitled to the money but whether the adjustment is the adjustment you asked for. The Taxpayer Advocate Service: "We made the changes you requested to your tax return for the tax year on the notice. You owe the IRS as a result of the changes." The tax has already been assessed — the deficiency stage (a Notice of Deficiency, with its 90-day Tax Court window) is behind this notice, not ahead of it, so there is no Tax Court route and no Appeals conference attached to this letter. The only dispute route printed on the notice is a phone call; the IRS's own page names a further Form 1040-X for a correction the notice does not mention, and nor does the notice mention audit reconsideration. Audit reconsideration is available where an examination is actually behind the assessment — but only while the tax remains unpaid (paying the bill to make it stop is what closes that door; if already paid, the route is an amended return to claim a refund). Reconsideration needs new information the IRS has not previously considered; the written route is a letter setting out each disputed issue or Form 12661, Disputed Issue Verification, with copies and the audit report if there is one; the IRS estimates 30 days to respond and says it may take longer. The date on the notice: a CP22A prints its payment date in more than one place (the Billing Summary, the "what you need to do immediately" steps, the payment stub, and the "if we don't hear from you" section), and on the IRS's own published specimen those dates are not all the same — find every date on yours and work to the earliest. The late-payment penalty is the one at 26 U.S.C. 6651(a)(3) and it does not run from the original due date — it starts 21 calendar days after notice and demand (10 business days if the amount equals or exceeds $100,000); the 5%/month failure-to-file penalty does not apply because your return was filed. 0.5%/month capped at 25% (6651(a)(3)), doubling to 1%/month after a levy notice (6651(d)), and halving to 0.25%/month during a payment plan for an individual who filed that year's return on time (6651(h)) — which you can apply for yourself on the IRS's site today. Interest under 6601 runs separately and is not capped. The IRS's Automatic Exemption from Penalty (IR-2026-83, 8 July 2026) is phased in (tax year 2025 income returns, 2026 quarterly returns) and conditioned on timely filing and payment for the three prior years — for an earlier year, First Time Abate is still the route and it must be requested. The IRS also publishes a penalty-removal invitation conditioned on contacting them by the due date if you cannot pay because of circumstances beyond your control ("may" and "depending" — not a guarantee). What happens if you do nothing: interest and a late-payment penalty accrue, and the account enters the ordinary collection sequence ("We'll assume you agree with the information in this notice if we don't hear from you"), starting with the CP14. Kentucky's note: if the federal change was a federal adjustment, KRS 141.211(2) gives a Kentucky taxpayer 180 days from the final determination date to file a federal adjustments report and pay any additional Kentucky tax — and where the change came from an amended return, the "final determination date" is the day the amended return was filed, so the Kentucky clock may already have started on the day you filed the thing that produced the CP22A; one year to assess on a timely report, six years if late/absent/understated.
- [LT16 — Money, a Missing Return, or Both](https://www.nextleveltaxresolution.com/irs-notices/lt16): A collection escalation letter that can be about two different problems — an unpaid balance, a return the IRS never received, or both at once — and which one it is changes everything about what you should do. The IRS: "If you received a simple LT16 notice, it's because we're trying to collect unpaid taxes from you and/or our files show we're missing tax returns from you." The and/or is the notice's actual scope: some LT16s go out on a balance, some because a required return has not been received, some on both. It sits before the Final Notice in the sequence (the IRS's warning that failing to act risks enforcement "can include seizing your assets or wages" is a description of where the sequence leads, not a statement that a levy is imminent — before the IRS can levy wages or a bank account it still has to send the Final Notice carrying your hearing rights: an LT11, Letter 1058 or CP90). There is no statutory deadline on an LT16; the date to work to is the one printed on your letter. The letter refers to being entitled to a hearing with the Office of Appeals and points at Publication 1660, but that is a general signpost to appeal rights, not the conferral of a Collection Due Process right — LT16 does not appear on the Taxpayer Advocate Service's list of notices carrying those rights and it does not include Form 12153; the letter that starts that 30-day clock is the Final Notice, which has not arrived yet. The central distinction: a payment plan, currently-not-collectible status and an Offer in Compromise all require required returns to be filed — sending money into an account with a filing gap resolves an amount and leaves the reason for the letters untouched (people routinely respond to the wrong half, sending a payment when what the IRS is missing is a form). If a return is missing and the IRS gets tired of waiting, it files one for you — a Substitute for Return prepared from income reported about you with none of the deductions you did not claim, so the balance is almost always higher than the real one, and then you are arguing a number down instead of filing a return (a different and harder problem; an IRS-prepared return under IRC 6020(b) also does not start the limitation period on assessment — only your own filed return does). If you cannot pay, asking for a payment plan is itself protective: §6331(k) bars levy while an installment agreement or offer-in-compromise request is pending, for 30 days after a rejection, during an appeal, and while an agreement is in effect (§6331(k)(3) borrows the §6331(i)(3) jeopardy exception; it does not stop a federal refund offset under §6402; a pending request suspends the 10-year collection period). If the balance is old, the 10-year collection period may be the most important fact and it is on the transcript rather than on the letter. Kentucky's note: if returns are the problem rather than the balance, Kentucky is where it gets more serious — KRS 131.1817 makes a taxpayer "delinquent" for failing to file a required return within 90 days of the due date after department contact regardless of any balance owed, and that status reaches professional and occupational licenses, attorney licenses (via the Kentucky Supreme Court), and vehicle registration; the department must give at least 20 days' notice by certified mail before submitting a name to a licensing agency, and once a license is affected it is not reissued or renewed until a written tax clearance is received. A Kentucky non-filer with no money owed can still be a delinquent taxpayer — there is no federal equivalent, and a zero balance is not protection.
- [Form 4180 — The Interview You Are Not Allowed to See First](https://www.nextleveltaxresolution.com/irs-notices/form-4180): The record of an interview a revenue officer conducts to decide whether an individual should be held personally liable for a business's unpaid trust fund taxes — the Report of Interview with Individual Relative to Trust Fund Recovery Penalty or Personal Liability for Excise Taxes (IRM 5.7.4.2.4(2)). It is evidence, not a determination: nothing is decided at the interview; what goes on the record about you is decided there, and the determination happens later on the strength of it. The IRS does not publish the form, and IRM 5.7.4.2.4(3) instructs the officer: "Do not give or mail Form 4180 to the potentially responsible person(s) or representative for completion by that person or for review prior to the interview" — it must be completed in person or over the phone (a Letter 3586 schedules the appointment), and the forms-database search for 4180 returns "Showing 0 - 0 of 0" (the related 2750/2751/2751A are unpublished on the same searches). Copies of old revisions circulate on practitioner sites; rehearsing from a version of unknown year is worse than no rehearsal because the interview is designed so answers are unrehearsed — that is the argument for a representative rather than a script. The interview tests two findings and only two, both required: responsibility (a "responsible person" has duty to perform, power to direct collection of trust fund taxes, accountability and authority to pay them, and authority to determine which creditors are paid; the officer identifies officers, directors, shareholders, those who hire and fire, who sign the 941, who control payroll/disbursements/voting stock, who make FTDs — ownership is not on the list; IRM 5.7.3.4.1.1 says being an officer or shareholder "cannot be the sole basis" and signature authority "may be merely a convenience") and willfulness (IRM 5.7.3.4.2: "No evil intent or bad motive is required" — paying a supplier instead of the deposit to keep trading meets it; "failure to investigate or correct mismanagement after being notified" satisfies it, which is why "my bookkeeper handled it" is a starting point not an answer; three where willfulness is hard — Combined Annual Wage Reporting, an IRC 3509 adjustment, a volunteer director/trustee of a tax-exempt where IRC 6672(e) may need actual knowledge). IRM 5.7.3.4.1.2 + Policy Statement 5-14: ministerial-act employees — a bookkeeper signing checks only under direction who cannot independently decide which bills are paid — "should generally not be held responsible"; the standard is "significant control" over finances. The form's shape: page 1 core willfulness/responsibility questions (can stand alone as an abbreviated interview; naming others with authority opens Sections IV–V); page 2 Sections IV–V when others had authority; page 3 Section VI PSP/PEO questions, Section VII excise only; page 4 narrative + signature. IRC 6672(e) exempts an unpaid volunteer board member "solely serving in an honorary capacity" with no day-to-day/financial participation and no actual knowledge — all three together. Two statutory rights in the room: IRC 7521(b)(2) lets you suspend the interview to consult a representative "regardless of whether the taxpayer may have answered one or more questions" (the summons carve-out is in the parenthetical — an interview initiated by an administrative summons is not suspended; IRC 7521(d) takes criminal investigations out entirely), and IRC 7521(c) means the IRS may not require a represented taxpayer to attend an in-person interview alongside their representative absent a summons — but that right attaches to "any interview described in subsection (a)," an in-person interview, and the manual permits a 4180 by phone, so the right not to attend does not by its terms reach a telephone interview. IRC 7521(a)(1) lets you make your own audio recording of an in-person interview on advance request — IRM 5.1.10.7.1 (24 April 2025): "The right to make an audio recording does not extend to telephone interviews." IRC 6304(a)(2) governs collection contact once represented (not contact/attendance): the IRS may not communicate with you in connection with collection if it knows you are represented, absent your consent, a court's permission, or a representative who fails to respond in a reasonable time — enforceable by a civil action under IRC 7433 via 6304(c); IRM 5.1.10.7.2: "If a valid Form 2848 is on file and covers all open periods contact must be made with the representative." If you decline: nothing happens to you directly, but the determination is made anyway on the documents and on other people's interviews — the officer documents "the reasons why it was not secured," and "a summons may be necessary to require the potentially responsible person's presence" (which disapplies both rights). The recommendation: do not attend a 4180 interview alone, because the one preparation that would make attending alone sensible — reading the form first — is the thing the manual instructs the officer to prevent. Kentucky's note: the Commonwealth's sales-tax and withholding exposures reach individuals under state law on the state's own criteria and timetable, independent of any federal TFRP determination, with their own protest window.
- [CP90C — The IRS Already Levied. What You Still Have](https://www.nextleveltaxresolution.com/irs-notices/cp90c): A post-levy Collection Due Process notice — the IRS has already levied your assets, and the notice informs you of your right to a hearing about it. The IRS: "We levied your assets for unpaid taxes and are informing you of your right to a Collection Due Process hearing." The Taxpayer Advocate Service lists it under Final Notice of Intent to Levy and Notice of Hearing, and the printed heading is "Notice of seizure and notice of your right to a hearing" — both halves are the notice: the first is history, the second is live. You have 30 days from the date printed on the notice to request the hearing on Form 12153 (26 CFR 301.6330-1: the period runs from the day after the date of the notice; actual receipt is not a prerequisite; the specimen prints a notice dated 23 January with a deadline of 22 February). Why no warning came first: §6330(a) requires a pre-levy CDP notice at least 30 days before any levy, but §6330(f) lists four exceptions — jeopardy (f)(1), a state tax refund levy (f)(2), a disqualified employment tax levy (f)(3), and a federal contractor levy (f)(4) — and the same subsection entitles you to a hearing "within a reasonable period of time after the levy." The CP90C is the delivery of that post-levy right; a CP297A follows a disqualified employment tax levy, a CP92/CP242 a state refund levy, a Letter 2439 a jeopardy levy, so a CP90C most often means the federal contractor limb. The faster question than the hearing: a levy release under §6343 is faster, and on a bank levy still inside the 21-day hold a release can reach the money before it moves — the bank holds levied funds 21 days before remitting them, and on a recent levy that is the only clock on this page that can still save money rather than argue about it. §6343 release grounds: balance paid, collection period expired, release helps you pay, an installment agreement whose terms don't allow the levy to continue, economic hardship, property worth more than the debt. On hardship the IRS distinguishes wages from bank accounts in two consecutive sentences: a wage levy causing immediate economic hardship "must be released," a bank or other account levy causing the same hardship "may be released" — must vs. may, a right vs. a request. §6343(d) separately allows property already taken to be returned where the levy was premature or did not follow administrative procedure — a narrower and later remedy, not the same thing as release. How to ask for a release: call the number on the levy (not the general helpline — the levy is account-specific), have the bank's or employer's fax number in front of you (that is how a release physically reaches the institution in time, and on a 21-day clock that difference is the money), state the hardship in figures, know whether your levy is the must-release or may-release kind, and ask for an installment agreement or offer in the same call — a pending request bars further levy under §6331(k) (from acceptance for processing; bars levy not lien; §6331(k)(3) borrows the jeopardy exception; does not stop a federal refund offset under §6402; suspends the 10-year collection period). Situations that change the answer: §6330(c)(2)(B) allows the underlying liability to be raised where you did not receive a notice of deficiency or have an opportunity to dispute it; §6330(b)(2) allows only one CDP hearing per taxable period; §6343 requires release where the liability is "unenforceable by reason of lapse of time"; §6334 exempts unemployment benefits, workers' compensation, certain disability payments, public assistance, child-support judgments, tools of a trade and a minimum wage amount, and a principal residence is exempt absent written judicial approval — but §6334(f) removes several of these exemptions from a continuing levy on federal payments under §6331(h). §6330(d)(1) gives 30 days from Appeals' determination to petition the Tax Court; if the 30 days has passed, an equivalent hearing is available for a year but without the levy bar, the collection-period suspension, or Tax Court review. What happens if you do nothing: two clocks, one still in your favor — the 21-day bank hold (the window in which money is still recoverable) and the 30-day hearing right; after both, the equivalent hearing is a conversation without protection, and the levy that already happened does not prevent the next one. Kentucky's note: the DOR can levy administratively without a court judgment once an assessment is final and tax is unpaid 30 days after demand, with a 10-day written notice floor under KRS 131.510(1); there is no state analogue to the CDP hearing right — Kentucky's review is a 60-day written protest at the assessment stage (KRS 131.110) with no second door; and KRS 131.672(3) provides that a bank levy through the state's financial institution data match system arises when the institution receives notice (a notice sequence, not the federal 21-day holding period, and it governs that specific matching system rather than every state bank levy).
- [Letter 1153 — Your 60 Days, and What They Are Actually For](https://www.nextleveltaxresolution.com/irs-notices/letter-1153): The preliminary notice that the IRS proposes to assess the trust fund recovery penalty against an individual — a proposal, not an assessment, and IRC 6672(b)(2) requires the IRS to wait at least 60 days after mailing it (75 if addressed outside the US) before issuing notice and demand (with one exception: 6672(b)(4), a jeopardy finding). Nothing has been assessed; the letter opens a window, and three details inside it decide most outcomes. The 60 days run from the date of mailing or personal delivery — not from receipt and not from the day you read it; the revenue officer is instructed to date-stamp or hand-write the date of service on the letter, and timeliness is measured on the postmark — a protest is timely if postmarked or mailed by certified or registered mail on or before the 60th day, and a private postage meter stamp is not evidence of when it was mailed (IRC 7503: if the last day falls on a Saturday, Sunday or legal holiday, the next business day counts; the IRS's five-day allowance for receipt and processing is the IRS's margin, not an extension; the ten-day informal contact invitation on the letter preserves nothing — only a written appeal within 60 days does). The $25,000 threshold that decides which appeal you file is measured on the total of all periods, not on each quarter — IRM 5.7.6.4: "If one tax period and/or the sum of all the tax periods is more than $25,000 the responsible person must submit a Formal Written Protest"; four quarters at $9,000 each is $36,000 and a Formal Written Protest is required, and the natural mistake is looking at the largest single quarter and reaching for the simpler Small Case Request — a mistake about form rather than time, and "a protest filed within the appropriate time frame is considered timely even if it is incomplete" (the clock forgives an incomplete protest; it is the wrong kind of protest, and no protest, that cause the damage). Filing a protest extends the ASED: it will not expire before 30 days after Appeals' final determination or 90 days after the Letter 1153 mailing, whichever is later. The penalty is the trust fund portion only — withheld income tax plus the employee's share of FICA — and it excludes the employer's matching half of FICA and the penalties and interest on the business account, so the number proposed against you personally is materially smaller than the business's balance; how much smaller depends on wage mix and on how the business's payments were applied across quarters, which the ATFR calculation sheets in the envelope show. The refund freeze: when a Letter 1153 delivery date is entered into the IRS's system, ATFR systemically uploads TC 130 (Entire Account Frozen from Refunding) to freeze your personal refunds — the trigger is administrative, it sits on your individual account, and it is reversible by TC 131 where the trust fund liability is paid in full or if the TFRP will not be assessed on any periods; a Letter 1153-W withdraws the proposal outright when new information changes the recommendation, and it cannot be issued once a protest has gone to Appeals. If you already signed Form 2751: IRM 5.7.4.7(2) (and again at 5.7.4.2.4(10)) — "Do not treat a signed Form 2751 as a conclusive waiver until the 60 or 75-day restriction period (plus five additional days) expires, as a responsible person may change their mind after signing the waiver. A responsible person's signature on Form 2751 does not extinguish their appeal rights" — it is an instruction to IRS employees about how to treat a signature during the restriction period, not a general right to change your mind at any time, and acting on it means filing the protest inside the same 60 days. IRC 6672(e) exempts an unpaid volunteer board member of a tax-exempt organization "solely serving in an honorary capacity" with no day-to-day/financial participation and no actual knowledge — all three together. What happens if you do nothing: after the period expires with no protest, the case is treated as unagreed and the penalty is assessed — you lose the route to Appeals but not the argument; IRM 5.7.6.7 says you may file Form 843 (Claim for Refund and Request for Abatement) once the TFRP is assessed, and §6672(c) provides a bond-and-refund route for stopping collection while the liability is litigated — it requires, within 30 days after notice and demand, paying at least the minimum amount to commence a court proceeding, filing a refund claim, and furnishing a bond of 1½ times the excess of the penalty assessed over the payment; a further 30 days runs from refund denial to begin the proceeding (so "longer, harder road" is right about effort and wrong about time: the door opens and closes inside a month of the assessment). §6672(d) gives a person who has paid more than their proportionate share a right to recover the excess from co-liable persons — a civil claim between the people, not something the IRS administers, belonging to a person who has paid (not one deciding whether to), brought as a separate proceeding not folded into the government's collection action; it is a lawyer's question rather than a CPA's. The protest is an evidenced account of your authority — or the absence of it — during specific quarters, written knowing what the revenue officer already recorded on Form 4180; responsibility is assessed period by period (someone who joined or left mid-way is not exposed on the whole span). Send the protest certified or registered and keep the receipt. Kentucky's note: the state reaches individuals for entity tax debts on its own criteria — sales tax the Commonwealth treats as held on its behalf, and Kentucky withholding, both create personal exposures under state law with their own definitions, their own protest window and their own consequences including against the licenses a person needs to work; a federal protest does not pause any of it, and where both are live the sequencing matters.
- [CP521 — Your IRS Payment Plan Reminder, Explained](https://www.nextleveltaxresolution.com/irs-notices/cp521): The monthly reminder that your IRS installment payment is due — the most routine letter in the collection sequence, the one where your plan is working, and the one with a real date on it that most coverage describes as a receipt with no deadline. The IRS: "It's a reminder to send in your monthly payment." The notice itemizes the failure-to-pay penalty and interest charged to date as separate running totals (the notice tells you how to derive the monthly figure: compare this month's lines with last month's — the difference is that month's charge), and the IRS groups CP521, CP521 (SP) and CP621 together on its own page (a CP621 is this letter). The sample prints a real date: "Your monthly payment of $300.00 must be received by February 20, 2019," and on the payment stub — "If we don't receive your payment of $300.00 by February 20, 2019, you may default on your installment agreement. If you default, you may have to pay a user fee to reinstate it." "May default," not "will" — a missed payment permits the IRS to act, it does not oblige it to, and the plan does not end on that date: §6159(b)(5) bars termination without at least 30 days' written notice and an explanation unless collection is in jeopardy, and that letter is the CP523 (paired with a Letter 2975(DO)) — the CP521 is the reminder; the CP523 is the notice. While an installment agreement is in effect, IRC §6651(h) halves the late-payment penalty from 0.5% to 0.25% of the unpaid tax per month "by substituting '0.25' for '0.5' each place it appears" — for an individual whose return for that year was filed on time including extensions (nobody applies for it; it follows from having the agreement); the ordinary 0.5%/month, a 1%/month rate after a levy notice under §6651(d), and interest under §6601 (set quarterly, no cap — the penalty caps at 25%, interest does not). The levy bar while a plan is in effect: §6331(k)(2)(C) bars levy "during the period that such an installment agreement for payment of such unpaid tax is in effect" — it covers the tax in the agreement and not a balance for a year outside it, and §6331(k)(3) carries across the §6331(i)(3) jeopardy exception; a pending installment-agreement or OIC request also bars levy (from the date the IRS accepts the offer for processing; bars levy not lien; does not stop a federal refund offset under §6402; suspends the 10-year collection period). What breaks plans without mentioning them: §6159(b)(4) covers "failure to pay an installment or any other tax liability when due" — the middle limb means an agreement covering 2022 can break when 2025 comes due and is not paid, nothing to do with the monthly payment, and the IRS may "alter, modify, or terminate" (not must), with a 30-day notice first. The sequence if it goes that way: CP521 (here) → CP522 (the IRS wants updated financials by telephone to keep the plan going) → CP166 (a direct debit did not clear, business accounts) → CP523 (intent to terminate and intent to levy, 30 days) → CP504 (intent to levy on a balance no longer under an agreement). The penalty comparison method that needs two notices rather than one, and why a new year about to produce a balance is the clause that ends most agreements and is almost entirely preventable (an adjusted withholding or an estimated payment in the year it arises). Kentucky's note: KRS 131.081(9)(a) gives a statutory right to an installment payment agreement (conditional on requesting it in writing and showing inability to pay in full and that it will facilitate collection); KRS 131.081(9)(b) lists five grounds to act (noncompliance with terms, a sufficiently changed financial condition, failure to provide a requested financial update, false or misleading information in securing the agreement, and — ground 5 — failure to timely report and pay any other tax due the Commonwealth, the state's version of the clause that ends federal agreements); KRS 131.081(9)(c) requires 30 days' written notice before modifying or terminating unless the department believes collection "will be jeopardized in whole or in part by delay" (jeopardy in part is enough). The Department of Revenue's Internet Payment Agreement terms — not in the statute — acknowledge "the validity of the tax due and all protest right of KRS 131.110 are extinguished" (entering the online agreement gives up the 60-day written protest window), a 24-month maximum and $50 minimum monthly payment (terms of the tool, longer negotiable with the Division of Collections), and "any state or federal tax refund or state vendor payment will still be offset and applied to the amount due."
- [CP522 — The IRS Wants Your Financials to Keep Your Plan](https://www.nextleveltaxresolution.com/irs-notices/cp522): A review of a live installment agreement — not a default notice; the IRS is reviewing your plan and needs updated financial information (Form 433-F, Collection Information Statement) to keep it going, and the review exists "to help us determine the correct monthly payment amount." The IRS says the payment "may decrease, increase, or stay the same based on the information you provide" — it is not an accusation, it carries no levy, and it is a term of the deal you made (the review arises when the agreement was granted for less than the minimum payment usually required). The instruction people miss, which produces exactly the outcome the letter warns about: the notice says "Don't mail us the form. You must call for this review," and the IRS's page explains why — "Do not mail Form 433-F to us. We will not receive it in time to prevent your installment agreement from being terminated." So the failure mode is doing the careful thing (filling the form in, putting it in an envelope, mailing it) and having it arrive after the decision — complete the form before you call, then call with it in front of you. The notice prints a short response date ("Please call us to provide updated financial information by [date], or your installment agreement will be terminated"); we do not publish a day count because the IRS's own published sample prints two different years for the same deadline (the correct year once, an erroneous one twice), so a number derived from it would be a number derived from a typographical error — the date that governs you is the one printed on your own letter. That date is not the date the agreement ends: §6159(b)(5) bars termination without "a notice of such action … not later than the day 30 days before the date of such action" and an explanation of why, unless collection is in jeopardy (which removes both) — so the CP522 is the request and the 30-day notice is a separate letter. The notice's verb is "will be terminated" and "we will bill you for the full amount of tax you owe"; the statute's under §6159(b)(4) ("Failure to pay an installment or any other tax liability when due or to provide requested financial information") is "alter, modify, or terminate" — three options, of which termination is one, and nothing obliges the IRS to take the third: worse numbers can mean a lower payment rather than the end of the plan, and the fear that keeps people from calling is usually about the numbers being worse. The §6331(k)(2)(C) levy bar is still running because a CP522 does not end the agreement. The skill in this: the IRS assesses necessary living expenses against published standards rather than against what you actually spend, and the 433-F categories do not map cleanly onto how a household's money really moves — two people with identical bank statements can complete a 433-F very differently, and the accurate and correctly categorized version is the one that produces a payment that survives; understating expenses produces a payment you cannot keep (and a CP523 later), and overstating falls under §6159(b)(3)/(b)(4) (alter/modify/terminate) while the terminate-only ground at §6159(b)(2) reaches only information provided before the agreement was entered into. The sequence: CP521 → CP522 (here) → CP166 → CP523 → CP504. Kentucky's note: KRS 131.081(9)(b) grounds 2 and 3 are this letter almost word for word (a sufficiently changed financial condition; failure to provide a requested financial condition update), the state writes modify before terminate, and §6159(b)(4)'s three options mirror KRS 131.081(9)(c) — 30 days' written notice before modifying or terminating unless collection "will be jeopardized in whole or in part by delay" (jeopardy in part is enough; covers modifying as well as terminating). The DOR's Internet Payment Agreement terms extinguish the KRS 131.110 protest right on entry, add that "any new liability will break the agreement and the full balance will become due immediately" (ground 5 restated as a contract term), and confirm refund/vendor offsets continue. One further difference: Kentucky's right to an agreement under KRS 131.081(9)(a) is conditional on a written request; the federal review you are being asked for happens on the telephone.
- [CP523 — The IRS Intends to End Your Payment Plan — and What Stops It](https://www.nextleveltaxresolution.com/irs-notices/cp523): The notice the IRS sends to tell you it intends to end your installment agreement and to levy — headed "Notice of intent to levy" and "Intent to terminate your installment agreement," and the 30 days printed on it is doing double duty: it is the notice period §6159(b)(5) requires before the IRS may terminate (with an explanation of why, unless collection is in jeopardy, which removes both), and it is also the statutory thirty days a levy notice carries under §6331(d). What it is not is a seizure date — a notice of intent to levy is a precondition to levying, not a levy — and the most valuable distinction on the page is defaulted vs. terminated. A defaulted agreement is not a terminated one: IRM 5.14.11.5(3) says agreements in default but not yet terminated "must be reinstated if taxpayers remedy the default (unless there is another reason for default)" — "must" is the manual's word, and "another reason" means one of the other four items on the five-item closed list at IRM 5.14.11.3 (which ends: "Installment agreements may not be defaulted nor terminated for reasons other than those listed in this section"). What triggered it: §6159(b)(4) covers "failure to pay an installment or any other tax liability when due or to provide requested financial information" — the middle limb means an agreement covering 2022 breaks when 2025 comes due and is not paid, nothing to do with the monthly payment, and the statute's grammar runs your way: (b)(2) (inaccurate info before the agreement, or jeopardy) permits terminate only, while (b)(3) (significantly changed financial condition) and (b)(4) (missed installment, another liability unpaid, or requested financial update not provided) permit "alter, modify, or terminate" — three options, of which termination is one, and nothing obliges the IRS to take the third. What happens if you do nothing: §6331(k)(2)(C) and (D) bar levy while an agreement is in effect, for 30 days after termination, and while a timely appeal is pending — and IRM 5.14.11.4(5) instructs staff that "no levies may be issued on tax periods included in agreements for 90 days after mailing Notice CP 523 or Letter 2975 (DO)" (the 90 days includes the 30-day notice period, a 15-day mailing allowance, the 30-day post-termination window, and its 15-day mailing allowance — they overlap, not sum; the 90 comes from the account moving to balance-due status 13 cycles after the notice; the paragraph carries a 1 January 2015 revision date). Two limits: it covers only tax periods included in the agreement (a year outside it is not covered — exactly the reader whose plan broke because a new year came due), and it is written for IDRS-monitored agreements. Your one appeal: a Collection Appeals Program request on Form 9423 is available within 30 days of the proposed termination or within 30 days of the actual termination — but not both (IRM 5.14.11.7(2): "If a CAP hearing is requested prior to termination, the taxpayer may not appeal the decision again once the termination takes effect"), with 15 days allowed each time for mailing; a second window sits at roughly days 30–60 from the notice date. CAP is not a CDP hearing — it carries no route to the Tax Court and does not suspend the 10-year collection period. Whether a Final Notice already went out on these periods changes what the IRS can do without writing again: the notice says that after termination and exhausted appeals the IRS can levy if it previously sent a CDP notice, and "if we haven't sent you a CDP notice, we're permitted to levy (seize) your state income tax refund and serve a Disqualified Employment Tax Levy or a Federal Contractor Levy" — so for wages and bank accounts a Final Notice (LT11/Letter 1058/CP90/CP297) usually comes first, but for a state refund, a DETL, and a federal contractor levy it does not; which applies is on the transcript, not the letter. Two routes to reinstatement without a financial statement (IRM 5.14.11.5(2)): (a) default/termination caused by an additional liability where adding it means no more than two extra payments and the CSED is not exceeded (a lien determination is required), or (b) streamlined criteria with no default in the prior 12 months — the 12-month condition attaches to (b) only, so a second default in a year does not close (a). Asking for a new agreement or an offer bars levy while pending under §6331(k) (for an offer, from the date the IRS accepts it for processing; bars levy not lien; does not stop a refund offset under §6402; suspends the 10-year collection period). The house: §6334 exempts a principal residence from levy unless a judge or magistrate of a U.S. district court approves it in writing (exclusive jurisdiction) — it happens, but it requires a court, not this letter. Social Security: a continuous levy under §6331(h) reaches up to 15% of benefits. CP523H (shared responsibility payment) carries no levy heading and the manual says no levies may be issued on those liabilities; CP523B went to a business. The sequence: CP521 → CP522 → CP166 → CP523 (here) → CP504 → LT11/Letter 1058. Kentucky's note: KRS 131.081(9)(c) requires 30 days' written notice before modifying or terminating unless collection "will be jeopardized in whole or in part by delay" (jeopardy in part is enough; covers modifying as well as terminating; same verb order as the federal rule), (9)(b) ground 5 is the state's version of the new-year clause, and the DOR's Internet Payment Agreement terms state "any new liability will break the agreement and the full balance will become due immediately" and extinguish the KRS 131.110 protest right on entry.
- [CP166 — Your IRS Direct Debit Payment Didn't Clear](https://www.nextleveltaxresolution.com/irs-notices/cp166): A business notice (the specimen's identifying field is an Employer ID number, though the IRS files the explainer under its individuals URL path — the URL is a filing convention, not the audience) reporting a failed direct debit on a live installment agreement — not a default and not a termination. The IRS: "We couldn't withdraw your monthly payment because there wasn't enough money in your bank account," and "We'll make a second attempt to withdraw your payment" — but neither the notice nor the IRS's page gives an interval for the retry, so the account should be funded now rather than by a date; fund it for the payment plus whatever your bank charged for the returned item (the notice's own instruction: "be sure you have enough money in your account to cover your monthly payment plus any fees your bank may have charged you for insufficient funds" — and the bank's fee is not on the IRS's letter). If the retry also fails, you "may default" — the notice's permissive verb — "interest will increase, and additional penalties may apply"; default is not termination, and §6159(b)(5) bars the IRS from terminating without at least 30 days' written notice and an explanation of why, unless it believes collection is in jeopardy (which removes both). While the agreement is in effect, §6331(k)(2)(C) bars levy on the covered tax. The statute does not oblige the IRS to end the agreement: §6159(b)(4) ("failure to pay an installment or any other tax liability when due or to provide requested financial information") permits "alter, modify, or terminate" — three options, of which termination is one; a payment that has become too large for the business's cash position is a candidate for the first two, and a modification asked for while the plan is in good standing is materially stronger than a reinstatement requested after a default. The clause that ends most business agreements is not the missed installment but the middle limb — "any other tax liability when due" (a new quarter coming due and unpaid breaks a plan on a clause nobody reads). The big question to check first: whether payroll (trust fund) tax is in the balance behind the agreement — unpaid withheld income tax and the employee's share of FICA can be assessed personally against responsible persons under §6672 on a separate track that has nothing to do with this letter or this agreement; a business with a cash-flow problem and payroll tax in a plan is standing closer to that than the envelope suggests. There is no current IRS page, specimen, or Internal Revenue Manual reference for a "CP57." The notice's published sample is an unpopulated template (notice date, tax period, and phone fields render as placeholders), so we do not reproduce a date from it and we are not telling you the CP166 carries no deadline, either — read yours. The sequence: CP521 → CP522 → CP166 (here) → CP523 → CP504. Kentucky's note: KRS 131.081(9)(c) requires 30 days' written notice before modifying or terminating unless collection "will be jeopardized in whole or in part by delay" (jeopardy in part is enough; covers modifying as well as terminating), (9)(b) ground 5 is the state's version of the new-year clause, the DOR's Internet Payment Agreement terms state "any new liability will break the agreement and the full balance will become due immediately" and that entering the online agreement extinguishes the KRS 131.110 protest right, and KRS 131.1817 lets the state reach professional/occupational licenses and vehicle registration — collection tools a federal plan does not touch, so a business carrying both balances should not assume the federal plan is the urgent one because the federal mail is louder.
- [CP515 — The IRS Still Has No Record of Your Return](https://www.nextleveltaxresolution.com/irs-notices/cp515): A reminder that the IRS still has no record of a past-due return it was expecting — and the specimen says something most coverage leaves out: "We sent you a previous notice informing you of this, but the notice may have been returned as undelivered or could not be mailed by the United States Postal Service (USPS)." A CP515 frequently reaches a person who never saw the first letter (a move, a lapsed forwarding order, a rental address the IRS never had), and it is one of a run of reminders (CP59, CP63, CP259, CP515, CP516, CP518, CP518B, CP2566, CP2566R, CP3219N) that precede letters with real deadlines. Nothing on it forfeits a right and there is no petition to file — it is a request for a return, not an audit, not a bill, not an enforcement step — but it does print a date that is about your money rather than the IRS's: a refund from withholding or estimated tax has to be claimed by filing within a limited period ("You risk losing your refund if you don't file your return"), and the same limit applies to credits such as the Earned Income Credit; that is the one thing on a CP515 that actually expires, and it expires in your direction (the IRS's published sample renders that date through a template that collides with its own instruction text, so the figure to work from is on your own letter). The notice offers three answers, not one: file the return (pay what you can; the balance is a separate problem), say you already filed (crossed post, a return under a different name or number, an e-file that rejected unnoticed), or say you were not required to file (income below the filing threshold, or income reported to the IRS that was not yours — the IRS's current page names Form 15103; the older printing encloses a Response form asking the same thing; where you are only explaining why you do not have to file, Form 15103 can be submitted online). If you do nothing: "We may determine your tax for you" — a return the IRS prepares from third-party income records allows nothing you did not claim, so the resulting balance is usually higher than a filed return would have produced, considerably so for anyone self-employed (gross receipts are reported to the IRS, costs are not); a refund on a different, filed year can also be held up by this unfiled one. The sequence: CP59 → CP515 (here) → CP516 → CP518 → CP2566 → CP3219N (Notice of Deficiency after the IRS filed for you — a hard 90-day Tax Court clock). Kentucky's note: the two systems do not talk to each other in the way people assume — a Kentucky return for the same year can be outstanding without a single federal letter mentioning it, and KRS 131.1817 lets the state reach professional and occupational licenses and vehicle registration; Kentucky's protections sit earlier in its process than the federal ones do in theirs, so by the time a state balance is being collected the door the federal system is still holding open has often already closed on the state side.
