IRS and tax debt terms, in plain English

An assessment is the moment the IRS formally records that you owe a specific amount for a specific year. Before that, a number may be proposed, discussed or disputed. After it, the balance exists as a debt the IRS can act on, and the collection clock starts running.

Assessment is followed by a Notice and Demand for Payment — the first bill. The IRS describes a federal tax lien as arising once it 'assesses your liability,' sends that bill, and the debt goes unpaid.

The CSED is the date the IRS's legal right to collect a particular tax debt runs out. The IRS generally has 10 years — from the date your tax was assessed — to collect the tax, along with the penalties and interest on it.

Each year's balance has its own CSED, so one account can hold several. And the clock can pause or be extended — bankruptcy does it, and so does living outside the country for six months or more, but so do several of the things you might do on purpose. A pending installment agreement request, a pending offer in compromise, a request for a CDP hearing and an innocent spouse claim all suspend it while they are open.

The Final Notice of Intent to Levy and Notice of Your Right to a Hearing is the letter the IRS must normally send before it takes wages or a bank account. It arrives as an LT11, a Letter 1058, or a CP90.

It is the letter people most often mistake for one of the earlier reminders, because by that point the reminders have all looked similar. It is not. It is the one carrying an appeal right, and that right expires.

A CDP hearing is your right to take a collection decision to the IRS Independent Office of Appeals before the money is taken. The IRS describes it as 'an opportunity to discuss alternatives to enforced collection,' and it also lets you dispute the amount if you have not had a chance to before.

You have 30 days to request one, using Form 12153, and those 30 days run from the date printed on the LT11 or Letter 1058 — not from the day it reached you. A Notice of Federal Tax Lien filing works slightly differently: the IRS must notify you within 5 business days of filing the lien, and your 30 days begins after that 5-business-day period ends.

A Notice of Deficiency is the letter that tells you the IRS proposes to change your tax, and gives you the right to challenge it in United States Tax Court before it is assessed. It arrives as a CP3219A or, where the IRS has filed a return for you, a CP3219N.

You have 90 days from the date on the notice to file a petition with the Tax Court — 150 days if the notice is addressed to you outside the United States. Talking to the IRS in the meantime is not the same as filing. The IRS says so plainly: working with the agency during those 90 days 'won't extend the time you have to respond or to file a petition.'

A revenue officer is an IRS employee who works collection cases in person rather than by computer. The IRS describes them as civilian employees who 'help resolve returns and taxes owed as part of the collection process.'

They now normally make contact by mailing an appointment letter or calling first, and they carry an IRS-issued pocket commission and an HSPD-12 card, both showing a serial number and photo. A revenue officer is not a revenue agent — that is the auditor — and is not a private collection agency.

A federal tax lien is 'the government's legal claim against your property when you neglect or fail to pay a tax debt.' It arises by law once the tax is assessed, billed and left unpaid. The Notice of Federal Tax Lien is the separate step where the IRS files a public document to alert your creditors that the claim exists.

The IRS is clear about the distinction people get wrong: 'A lien is not a levy. A lien secures the government's interest in your property when you don't pay your tax debt. A levy actually takes the property to pay the tax debt.' A filed notice can sometimes be withdrawn, which takes the public notice off while the debt remains. It can be discharged from one specific piece of property. Or it can be subordinated, letting another lender go ahead of the IRS — which is often what makes refinancing possible.

A levy is the IRS taking property to satisfy a tax debt. In the agency's own words, it 'permits the legal seizure of your property.' Before it does that to wages or a bank account, it normally has to send the Final Notice of Intent to Levy first.

One thing that is often grouped under this word does not belong there. A refund offset — the IRS applying a refund you were owed against a balance you owe — is not a levy. It runs under different rules, which is why it arrives without a Final Notice and without the appeal right that goes with one.

A bank levy freezes the money in your account on the day it lands and sends it to the IRS after a waiting period. When the IRS levies a bank, 'funds in the account are held and after 21 days sent to the IRS.'

Those 21 days are the reason a bank levy is not as final as it feels on the first morning. Money deposited after the levy date is generally not caught by that levy.

A wage levy takes part of each paycheck, and unlike a bank levy it does not stop on its own. IRS wage levies 'are continuous and a portion of your wages is exempt from levy,' with the exempt amount depending on your filing status and dependents.

Because it is continuous, it keeps taking until something replaces it — usually an agreement, hardship status, or a demonstration that the underlying balance is wrong. Waiting it out is not one of the options.

A Substitute for Return is a return the IRS prepares for you when you have not filed one. The IRS puts it plainly: 'If you fail to file, we may file a substitute return for you. This return might not give you credit for deductions and exemptions you may be entitled to receive.'

It is followed by a Notice of Deficiency, and if nothing is done, the proposed amount is assessed and collection begins.

An installment agreement is a formal payment plan with the IRS. A short-term plan runs up to 180 days and does not carry the setup fee a long-term agreement does. On a long-term agreement the fee is lower if you apply online and pay by direct debit, and it is waived for low-income applicants who pay by direct debit.

The plan you get is not simply the payment you can afford. Which type you qualify for depends on the balance, how you apply, and whether you are current on this year's filings.

The Simple Installment Agreement is the IRS's current standard payment plan for individuals. It took effect March 5, 2025, and it replaced the Streamlined Installment Agreement for individual taxpayers. It is for taxpayers with a total balance less than $50,000 in combined tax, penalties and interest — the ceiling is measured on the whole balance, not on the tax alone — and it runs up to 120 months, or the CSED, whichever is shorter.

Direct debit is not what buys you protection from a Notice of Federal Tax Lien. It is, however, required by the IRS for balances between $25,000 and $50,000, so for most people in that range it is not optional anyway.

A PPIA is a payment plan for people who cannot pay the balance in full before the collection clock runs out. The Taxpayer Advocate Service describes it as an option 'for taxpayers who have a tax balance but are unable to full pay the balance within the remaining time the IRS has to collect.'

You pay what the IRS agrees you can afford. Any balance still outstanding when the CSED arrives 'will cease to be collected.' The IRS 'will ask you for updated financial information at least every two years,' and the agreement can default if you do not respond.

An Offer in Compromise is an agreement that settles a tax debt for less than the full amount. The IRS 'generally approve[s] an offer in compromise when the amount you offer represents the most we can expect to collect within a reasonable period of time,' weighing your ability to pay, income, expenses and asset equity.

To be eligible you must have filed all required returns, made required estimated payments, not be in an open bankruptcy, and — if you are an employer — be current on your federal tax deposits.

Source: IRS, "Offer in compromise," reviewed 25 August 2026.

The minimum offer amount is what the IRS's own worksheets calculate as the least it will consider — your available asset equity, plus a multiple of your monthly income after allowable expenses. The multiple depends on whether you pay it as a lump sum or over time.

You will also see this called reasonable collection potential, or RCP. It is worth knowing that the phrase does not appear in the Form 656-B booklet the IRS gives taxpayers. It is internal and practitioner language, and it means the same thing.

Currently Not Collectible is a status the IRS uses when, in the Taxpayer Advocate Service's description, 'a taxpayer and the IRS agree the tax is owed but a taxpayer cannot pay due to their current financial situation.'

Collection stops while the status holds. The debt does not go away, penalties and interest continue, and the IRS can review your finances again later and restart.

First Time Abate (FTA) is the IRS's standard administrative relief for a taxpayer with a clean recent compliance history. You have to ask for it. The Automatic Exemption from Penalty (AEP) is replacing it, and does not have to be requested. Announced in IR-2026-83, July 8, 2026, it covers failure to file, failure to pay, failure to deposit penalties and requires timely filing and payment for the three prior years. Nothing is required of the taxpayer — the relief is applied systemically. It does not cover tax and interest still due, plus any penalties not eligible for relief.

Which one applies depends on the year. AEP is being phased in: it applies to eligible original returns beginning with tax year 2025 and 2026 quarterly returns, and it fully replaces First Time Abate only for returns with original due dates on or after January 1, 2027.

Innocent spouse relief can release you from tax that arose because a spouse understated what was owed on a joint return without your knowledge. Requesting it on Form 8857 asks the IRS to consider all three kinds of relief: innocent spouse, separation of liability, and equitable relief.

The IRS states: 'You must request innocent spouse relief within 2 years of receiving an IRS notice of an audit or taxes due because of an error on your return.' That two-year limit governs innocent spouse relief and separation of liability. It does not govern equitable relief, which is timed against the collection period instead — so being past two years is a reason to find out which type applies, not a reason to assume the door is shut.

Audit reconsideration is, in the Taxpayer Advocate Service's words, 'a process that reopens your IRS audit.' It exists for people who have new information, who disagree with the assessed amount, who never appeared for the audit, or who had moved and never received the report.

You send the audit report (Form 4549) if you have it, and the documents supporting your position.

Trust fund taxes are the amounts an employer withholds from employee pay — income tax and the employee share of Social Security and Medicare — and holds on the government's behalf until they are deposited.

The name is the point. That money was never the business's to use.

Source: IRS, "Employment taxes and the Trust Fund Recovery Penalty (TFRP)," reviewed 25 August 2026.

The TFRP is how the IRS collects unpaid trust fund taxes from individuals when the business does not pay. 'The amount of the penalty is equal to the unpaid balance of the trust fund tax.'

It is not a fine added on top. It is the same money, moved onto a person.

Source: IRS, "Employment taxes and the Trust Fund Recovery Penalty (TFRP)," reviewed 25 August 2026.

These are the two findings the IRS has to make before assessing a TFRP against you. A responsible person is 'a person or group of people who has the duty to perform and the power to direct the collecting, accounting, and paying of trust fund taxes.'

Willfulness is the part people misread. The IRS sets a low bar for it. The person must have 'been, or should have been, aware of the outstanding taxes.' They must then have 'either intentionally disregarded the law or was plainly indifferent to its requirements.' And the IRS adds the sentence that surprises everyone: 'no evil intent or bad motive is required.'

Form 4180 is the 'Report of Interview with Individual Relative to Trust Fund Recovery Penalty or Personal Liability for Excise Taxes.' It is a structured interview a revenue officer conducts to establish whether you were a responsible person and whether the failure was willful.

If the IRS concludes you were, it sends Letter 1153, proposing the assessment. From the IRS's own guidance: 'You have 60 days (75 days if this letter is addressed to you outside the United States) from the date of this letter to appeal our proposal.'

A Notice of Tax Due is the Kentucky Department of Revenue's assessment letter — the state's equivalent of the first federal bill, and the start of the state's own collection process.

You have 60 days from the date printed on the notice — not from the day it arrives — to protest it in writing, under KRS 131.110. If you do not, the assessment becomes due and payable.

A written tax clearance is the Department of Revenue's confirmation that a tax matter is resolved. Under KRS 131.1817, a professional or occupational license 'shall not be reissued or renewed... until a written tax clearance has been received from the department.'

The same statute lets the department reach professional and occupational licenses, attorney licenses through the Kentucky Supreme Court, and vehicle registration. A taxpayer counts as delinquent for this purpose if a required return has not been filed within 90 days of its due date, or extended due date, after the department makes contact — regardless of the balance owed. The department must give at least 20 days notice by certified mail first.

An occupational license tax is a local tax on wages earned or business conducted inside a Kentucky city or county. It is levied by the local government, not by the state and not by the IRS, and it is administered locally too.

An account transcript is the IRS's record of activity on one tax year for one taxpayer. The IRS says it 'shows basic data such as filing status, taxable income, and payment types,' and — the part that matters — 'It also shows changes made after you filed your original return.'

It is one of several types. The wage and income transcript 'shows data from information returns we receive such as Forms W-2, 1098, 1099, and 5498,' which is what makes reconstructing an unfiled year possible.

Form 2848 is the document that authorizes someone to represent you before the IRS. Signing it 'allows the individual or individuals named to represent you before the IRS and to receive your tax information' for the years and matters listed on it.

A submitted Form 2848 is recorded in the Centralized Authorization File (CAF), the system IRS staff check to confirm that a representative is authorized. Not everyone can be named on one: the IRS requires 'an individual authorized to practice before the IRS,' which is a defined set of credentials rather than a job title.
