What a CP207 is
A CP207 says the liability schedule attached to a Form 941 was rejected, and asks for a corrected one. The IRS's own words:
"We are notifying you that your deposit schedule, the Record of Federal Tax Liability (ROFTL), contains missing or incorrect information. We need additional information from you."
The notice itself explains why it cares:
"We found errors or missing information in the Record of Federal Tax liability (ROFTL) section of your [period] Form number (941). We need this information to verify the timeliness of your required deposits against your actual tax liability amounts and the dates these liabilities were incurred."
Read that last clause slowly, because it is the whole thing. The IRS knows what you deposited and when — those are its own records. What it does not know is when each liability arose, and without that it cannot match one to the other. The Schedule B is the only document that supplies it.
The IRS added an answer in September 2025 listing exactly what gets a schedule rejected: "We reject ROFTLs with incorrect, missing, illegible, negative entries, or the total liability did not equal the total tax." Four of those five are clerical. The fifth — total liability not equaling total tax — is the one that means something is actually wrong with the return.
A note on the code. If your notice reads CP207L rather than CP207, it is the same letter doing the same job. The two sample notices the IRS publishes are near-identical: the wording differs by three words in one sentence, and the specimens print different placeholder dates. Nothing about what you have to do changes.

Your clock
The IRS publishes a period, and it names its trigger: "Complete a new ROFTL and mail to the address at the top of your notice within 45 days of the date on your notice."
Two things to hold about that 45 days.
It is a published instruction, not a statutory deadline. Nothing you are entitled to closes at day 46. What happens instead is described below — the IRS computes the penalty on averaged figures rather than on real ones — and that is a worse position rather than a lost right.
And your own letter may not say "45 days" at all. The sample notices the IRS publishes print an absolute date instead — "so we receive it by [date]" — rather than a day count. The date printed on your notice is the one that governs. If you have the letter and this page in front of you and they seem to disagree, believe the letter.

What happens if you do nothing — the averaging
This is the mechanism, and it is the reason the page exists. Publication 15 sets it out:
"The FTD penalty is figured by distributing your total tax liability shown on Form 941, line 12; Form 943, line 13; Form 944, line 9; or Form 945, line 3, equally throughout the tax period. Then we apply your deposits and payments to the averaged liabilities in the date order we received your deposits. We figure the penalty on any tax not deposited, deposited late, or not deposited in the correct amounts. Your deposits and payments may not be counted as timely because the actual dates of your tax liabilities can't be accurately determined." — IRS Publication 15 (Circular E), for use in 2026, page 37
Work through what that does to a real business. Suppose your payroll is monthly and lands at the end of each month. Your liability arises three times in the quarter, in three lumps, and you deposit against each one on time. Averaging replaces those three lumps with an even spread across every day of the quarter — which means a liability is treated as having arisen in the first week of the quarter, before your first payroll ran. Your first deposit, made on time against a liability that did not yet exist under the averaged version, arrives "late" against a liability the average invented.
The IRS says as much in its own last sentence: your deposits "may not be counted as timely because the actual dates of your tax liabilities can't be accurately determined."
Two limits on the averaged penalty, both from the paragraph immediately above the one just quoted, and both are good news. Publication 15 describes it as an "'averaged' FTD penalty of 2% to 10%" — the 15% rung does not apply to it — and it is assessed only where the quarter's tax liability "equaled or exceeded $2,500." Below that threshold, averaging is not in play at all.
Where the ladder itself comes from, and a discrepancy worth knowing about
The general deposit-penalty ladder is Publication 15 (2026), page 36:
| Rate | Charged for |
|---|---|
| 2% | Deposits made 1 to 5 days late |
| 5% | Deposits made 6 to 15 days late |
| 10% | Deposits made 16 or more days late, but before 10 days from the first IRS notice asking for the tax |
| 10% | Amounts that should have been deposited but were paid directly to the IRS, or paid with the return — subject to the "payment with return" exceptions in Publication 15 |
| 15% | Amounts still unpaid more than 10 days after that first notice, or after notice and demand for immediate payment, whichever is earlier |
Your CP207 prints a slightly different fourth rung, and that is not a misprint. The sample notice and the IRS's CP207 page both give it as "10% for amounts subject to electronic deposit requirements but not deposited using EFTPS", where Publication 15's fourth rung is the "paid directly or with the return" one. They are two different lists. If a rate on your letter does not match a rate on a website, the letter is describing your account and the website is describing the current published rule — and on this point the notice's wording is the older of the two.

Two things that are better than they look
A late reply is not a lost reply. The IRS updated its own page in September 2025 to say so: "If your response is late, we'll assess the penalty and then review your response to adjust the penalty as needed." Missing the 45 days means the penalty is assessed first and reviewed second. It does not mean the schedule stops mattering.
And you can avoid the whole thing next quarter for free. Publication 15's own advice, in five words: "You can avoid an 'averaged' FTD penalty by reviewing your return before you file it."
What triggered it
Almost always something mechanical, and the list is short.
| What happened | Why the schedule was rejected |
|---|---|
| A monthly depositor became semiweekly | Monthly totals were entered where day-by-day liabilities were required |
| Deposits were entered instead of liabilities | The schedule records what you owed, not what you paid |
| An adjustment produced a negative entry | Negative amounts are rejected outright |
| The schedule was omitted | Semiweekly depositors must attach Schedule B; monthly depositors complete line 16 |
| The totals do not tie | Schedule B total must equal total tax on the return |
If a deposit schedule change caused this, the earlier notice explains it. CP136, the notice that changed your schedule.
The IRS's own instructions for a schedule it will accept, quoted because getting one detail wrong sends it back:
"Report each tax liability. If you're on a monthly schedule, list the total liability for each month. If you're on a semi-weekly schedule, list the tax liability amount for each pay date. Report only liabilities, not your deposits. Don't show negative amounts. If you need to make an adjustment that results in a decrease in your tax liability, apply the decrease to the corresponding tax liability amount, but don't go below zero. Apply any remaining decrease to later liability amounts. Check that the total amount on your ROFTL schedule matches the total tax liability on your return."
The sequencing trap
If a deposit penalty is already on the account, you cannot ask for it to be removed first. The IRS says so plainly:
"We can't consider requests to remove deposit penalties unless we have a correct ROFTL. If you believe you had reasonable cause for making a deposit late, include a statement signed under penalty of perjury with your reply."
So the schedule leads and the reasonable-cause statement travels with it, in the same envelope. The IRS's instruction is explicit about that second half: the statement goes with your reply, signed under penalty of perjury. What does not work is a reasonable-cause letter on its own — it is answered by a request for the schedule, and the clock the letter was trying to beat has run on in the meantime.
There is one more right worth knowing about here, and it has its own short window. Publication 15:
"If you receive an FTD penalty notice, you may designate how your deposits are to be applied in order to minimize the amount of the penalty if you do so within 90 days of the date of the notice."
That is a genuine lever — the same deposits, applied in a different order, can produce a materially smaller penalty. It is 90 days from the date of the penalty notice, and the procedure is in Revenue Procedure 2001-58.
