## What is the penalty for filing Form 941 late?

The Form 941 late filing penalty is 5% of the unpaid tax for each month or part of a month, up to 25%. A late 941 with every deposit made on time owes no filing penalty. Late deposits add 2% to 15%, late payment 0.5% a month, and unpaid withholding can become a personal debt.

The Form 941 late filing penalty is the smallest of the payroll penalties and the one owners ask about first. By the time a quarterly return is late, the expensive part has usually happened already: a deposit that did not go out on payday, then another, while the payroll provider’s dashboard said everything was fine. We see it most in files where payroll liabilities in QuickBooks Online have not been reconciled for months, so nobody knew the balance was growing.

This post works through each penalty that can land on one quarter’s Form 941, in the order the IRS charges them, with the figures from the IRS’s own pages and Publication 15 for 2026. It then puts numbers on one late quarter and covers the trust fund recovery penalty, relief, and where the money went wrong in the books. Ledgerbrook keeps books and does not file returns or represent anyone before the IRS. Anything involving a notice, a payment plan or the trust fund recovery penalty belongs with a CPA, enrolled agent or tax attorney. To run a quarter of your own, use the [IRS penalty calculator](/tools/irs-penalty-calculator/).

## The Form 941 late filing penalty

A late 941 is charged the failure-to-file penalty under IRC §6651(a)(1): 5% of the unpaid tax for each month or part of a month the return is late, up to 25% ([Publication 15](https://www.irs.gov/publications/p15), 2026, section 12). The base is the tax still unpaid on the due date. Deposits made by then are subtracted first (IRC §6651(b)(1)).

That one detail settles the question most often searched with this one. **A 941 filed late with all of its tax deposited on time owes no failure-to-file penalty,** because 5% of zero is zero. The return still has to be filed, and filing it late is not free of risk, but the penalty itself is a percentage of tax that was not paid. Partnership and S corp returns work differently and are charged per owner even with no tax due; those are covered in [business tax deadlines](/blog/business-tax-deadlines/).

Part of a month counts as a whole one, so a return filed one day late is one month late.

### Form 941 due dates for 2026

The 941 is due the last day of the month after the quarter ends. A deadline on a weekend moves to the next business day (IRC §7503). An employer that made every deposit on time and in full gets 10 more days, to the 10th of the second month ([Instructions for Form 941](https://www.irs.gov/instructions/i941), Rev. March 2026).

| Quarter | Due | Due if every deposit was on time |
| --- | --- | --- |
| Q1 2026 (Jan to Mar) | Apr 30, 2026 | May 11, 2026 |
| Q2 2026 (Apr to Jun) | Jul 31, 2026 | Aug 10, 2026 |
| Q3 2026 (Jul to Sep) | Nov 2, 2026 | Nov 10, 2026 |
| Q4 2026 (Oct to Dec) | Feb 1, 2027 | Feb 10, 2027 |

October 31, 2026 is a Saturday and January 31, 2027 a Sunday, which is why Q3 and Q4 move. May 10, 2026 is a Sunday, so the Q1 extended date is Monday, May 11.

## The failure-to-deposit penalty

Employment taxes are not paid with the 941. They are deposited during the quarter by electronic funds transfer, on a monthly or semiweekly schedule set by the taxes reported in the lookback period: monthly at $50,000 or less, semiweekly above it (Publication 15, section 11). Monthly depositors deposit each month’s taxes by the 15th of the next month. The failure-to-deposit penalty under IRC §6656 applies to any amount not deposited in full and on time:

| Deposit | Penalty on the amount late |
| --- | --- |
| 1 to 5 calendar days late | 2% |
| 6 to 15 calendar days late | 5% |
| 16 or more days late, before 10 days after the first IRS notice | 10% |
| Paid directly to the IRS or with the return instead of deposited | 10% |
| Unpaid more than 10 days after the first IRS notice, or on the day of a demand for immediate payment | 15% |

Source: Publication 15, section 11, and the IRS [failure to deposit penalty](https://www.irs.gov/payments/failure-to-deposit-penalty) page (read October 30, 2026). The rates do not stack. A deposit 20 days late is charged 10%, not 2% plus 5% plus 10%. Days are counted from the deposit’s due date, not the 941’s.

The 10% for paying with the return has an exception that small employers rely on. If the quarter’s total tax is under $2,500 and the prior quarter’s was too, the tax can be paid with a timely filed 941 instead of deposited, with no penalty (Instructions for Form 941).

Payroll liabilities in QuickBooks that never clear to zero?

That is a cleanup, not a one-off fix: $99 per month of backlog (20% off 6+ months), one fixed price agreed before any work starts. [Send the file for a free 48-hour review](/contact/?from=blog%2F941-late-filing-penalty).

### Late deposits are applied to the newest liability first

When a deposit finally goes in, the IRS applies it to the most recent tax liability in the quarter, not the oldest. Publication 15’s example: $1,000 is due April 15 and $1,500 on May 15; the April deposit is missed, and $2,000 goes in on May 15. $1,500 covers May, and only $500 reaches April, leaving $500 of April late.

You can change that order. Within 90 days of the date on a failure-to-deposit penalty notice, you may designate how the deposits should be applied to reduce the penalty, following the instructions on the notice (Publication 15; Rev. Proc. 2001-58). This is worth an hour with the payroll register whenever a notice arrives, because the IRS default is rarely the cheapest order.

### The “averaged” penalty from a Schedule B mistake

The IRS can also charge an averaged failure-to-deposit penalty of 2% to 10% when a quarter’s tax is $2,500 or more and the deposit record on the return is wrong: a monthly depositor who leaves line 16 blank, or a semiweekly depositor who skips Schedule B or fills it in with deposits instead of liabilities. The IRS then spreads the quarter’s tax evenly over the period and tests your deposits against that. Deposits made on time can be counted late. The check before filing is that line 16, or the bottom of Schedule B, equals line 12, with liabilities entered on the dates employees were paid (Publication 15, section 11).

## Failure to pay and interest

Tax still unpaid after the 941’s due date is charged the failure-to-pay penalty under IRC §6651(a)(2): 0.5% a month or part of a month, up to 25%. In a month when both the filing and payment penalties run, the filing penalty is cut by the payment penalty, so the two together cost 5% a month for the first 5 months (Publication 15, section 12). The payment rate rises to 1% a month if the tax is still unpaid 10 days after a notice of intent to levy ([IRS failure to pay penalty](https://www.irs.gov/payments/failure-to-pay-penalty)). The reduced 0.25% rate under a payment plan is for individuals who filed on time, so it does not help a business with a late 941.

Interest is separate and is not a penalty, so it cannot be waived for reasonable cause. It runs at the federal short-term rate plus 3 points, set each quarter, and compounds daily (IRC §6621 and §6622). The rate was 7% for the first quarter of 2026, 6% for the second, and 7% for the third and fourth ([IRS quarterly interest rates](https://www.irs.gov/payments/quarterly-interest-rates)). It runs on the unpaid tax from the 941’s due date, and on the failure-to-file penalty from the same date (IRC §6601(e)(2)(B)).

## One late quarter, worked through

A business with $18,000 of employment tax for Q3 2026 deposited $12,000 on time. The September deposit of $6,000, due October 15, was missed, and the owner filed the 941 and paid the $6,000 with it on December 15, 2026. The return was due November 2.

| Charge | How it is figured | Amount |
| --- | --- | --- |
| Failure to deposit | 10% of $6,000 (more than 15 days late) | $600.00 |
| Failure to file | 2 months or part months at 4.5% of $6,000 | $540.00 |
| Failure to pay | 2 months at 0.5% of $6,000 | $60.00 |
| Interest | 7% compounded daily from Nov 2 to Dec 15, on the tax and the filing penalty | $54.15 |
| **Total** | | **$1,254.15** |

The two months are November 3 to December 2 and December 3 to December 15; the second is a part month and counts in full. Had the owner deposited the $6,000 and filed by November 2, the late deposit would still have cost $600, but the filing and payment penalties would have been zero.

Leave the same $6,000 unpaid until May 10, 2027, more than 10 days after the first IRS notice, and the bill becomes $2,731.27: $900 for the deposit (15%), $1,350 for filing (the 22.5% maximum), $210 for payment (7 months) and $271.27 of interest, assuming the rate stays at 7% after December 2026. The rates for 2027 had not been announced when this was written.

## The trust fund recovery penalty

Of the $18,000 above, part was never the business’s money. Federal income tax withheld from paychecks and the employees’ half of Social Security and Medicare are trust fund taxes: the business holds them for the government. When they go unpaid and cannot be collected from the business, the IRS can assess the trust fund recovery penalty under IRC §6672 against each person responsible for paying them who acted willfully. It equals 100% of the unpaid trust fund tax (Publication 15, section 11; IRS: [employment taxes and the trust fund recovery penalty](https://www.irs.gov/businesses/small-businesses-self-employed/employment-taxes-and-the-trust-fund-recovery-penalty-tfrp), read October 30, 2026).

What it covers, and what it does not:

- **Included:** withheld federal income tax, and the employee share of Social Security and Medicare.
- **Not included:** the employer’s matching share of Social Security and Medicare, FUTA, and the penalties and interest on the business account. Those stay with the business.

Who can be responsible: anyone with the duty and the power to collect, account for or pay the taxes. Publication 15 names officers, employees, partners, accountants, volunteer directors and anyone who signs checks or can direct spending. “Willfully” does not require bad intent. The IRS says paying other creditors with available money while knowing the payroll taxes are unpaid shows willfulness, and an employee who only pays bills as told by a superior is not a responsible person.

Before assessing it, the IRS sends a letter proposing the penalty. The person named has 60 days from the date of the letter to appeal, 75 days if it is addressed outside the United States. After that it is assessed personally and collected from personal assets. Hiring a payroll company does not shift the responsibility: Publication 15 says using a third-party payer generally “doesn’t relieve an employer of the responsibility” to make sure returns are filed and taxes are paid, with an exception for a certified professional employer organization.

If a letter like this has arrived, stop reading blog posts and call a tax professional who represents clients before the IRS.

## How 941 penalties are reduced or removed

### First Time Abate

The IRS will remove a failure-to-file, failure-to-pay or failure-to-deposit penalty for one return period when you have a clean history: for a quarterly return, the 12 prior quarters filed on time with no penalties, or with penalties later removed for reasonable cause ([IRS: penalty relief due to First Time Abate](https://www.irs.gov/payments/penalty-relief-due-to-first-time-abate-or-other-administrative-waiver), read October 30, 2026). Business accounts face extra tests for deposit penalties, and the manual rules out First Time Abate on a business account with four or more deposit-penalty waiver codes in its three-year history (IRM 20.1.1.3.3.2.1). Ask by phone at the number on the notice or in writing on Form 843. Interest on a removed penalty comes off too; interest on the tax does not.

### Reasonable cause

Each penalty can be removed if the failure was due to reasonable cause and not willful neglect. Reply to the penalty notice with the explanation. The Instructions for Form 941 say not to attach it to the return.

### The first-deposit waiver

Publication 15 describes a narrower waiver for a deposit penalty when the employer inadvertently failed to deposit in the first quarter it was required to, or the first time after its deposit frequency changed, as long as the return was filed on time. It also requires net worth of no more than $2 million for an individual, or $7 million and no more than 500 employees for a business. The IRS may also waive the penalty the first time a required deposit is sent directly to the IRS instead of by EFT.

## Recording 941 penalties in the books

Penalties are not deductible (IRC §162(f)). Post them to a separate expense account, not to Payroll Taxes, so the deduction for the employer’s real payroll tax stays clean and the CPA can see the add-back. The worked example above, paid in one amount, matches one line on the bank statement:

| Account | Debit | Credit |
| --- | --- | --- |
| Payroll Liabilities | 6,000.00 | |
| Penalties and fines | 1,200.00 | |
| Interest expense | 54.15 | |
| Checking | | 7,254.15 |
| **Total** | **7,254.15** | **7,254.15** |

The $6,000 clears the liability the September payroll created. Whether the interest is deductible depends on the entity and the tax, so ask the preparer before the return is filed.

## Where 941 penalties start in the books

Late deposits rarely start with a decision not to pay. They start with a payroll liability nobody is watching:

1. **The payroll provider did not deposit**, because the bank debit failed or the account was not funded, and the notice went to an old address.
2. **A manual payment was posted in QuickBooks but never sent**, so the liability shows paid in the books and unpaid at the IRS.
3. **The provider’s journal entries were imported twice, or not at all**, so the Payroll Liabilities balance stopped meaning anything months ago.
4. **Cash ran short and payroll went out net**, with the deposit pushed to “next week”.

Each of these shows up the same way: a payroll liability account in the books that does not fall back to zero after each deposit. How to tie the books to the payroll register, the bank and the 941 each month is in [payroll reconciliation](/blog/payroll-reconciliation/). The year-end side, with the W-2s and the fourth 941, is in the [year-end payroll checklist](/blog/year-end-payroll-checklist/), and owners with several years of unfiled returns should read [behind on business taxes](/blog/behind-on-business-taxes/).

## Common questions about late 941s

### How late can you file Form 941?

There is no cutoff after which it can no longer be filed. File every missing quarter as soon as possible, on the revision of the form for that quarter, because the failure-to-file penalty grows each month until it reaches 25%.

### Is there a grace period for Form 941?

Only the 10 extra days for an employer whose deposits were all made on time and in full. Deposits have no grace period; one day late is 2%.

### What happens if I don’t file Form 941 at all?

The penalties keep running until they reach their caps, interest keeps compounding, and the IRS can prepare the return itself from the information it has (IRC §6020(b)). Unpaid withholding also opens the trust fund recovery penalty against the people responsible. File the returns even if the tax cannot be paid yet; that stops the filing penalty and the payment plan can come after.

### What is the penalty for a late EFTPS payment?

The failure-to-deposit table above. EFTPS is the system the deposit goes through, and the penalty depends only on how many calendar days late the deposit reached the IRS.

### Is Form 944 or 940 different?

The same deposit and filing rules apply to Form 944, the annual return for the smallest employers (Publication 15). Form 940 for FUTA has its own rule: FUTA tax is deposited for any quarter in which it is over $500, counting amounts carried forward from earlier quarters (Publication 15, section 14).

## When payroll liabilities have not reconciled for months

The penalties above are a percentage of a number, and the number is only knowable from books where payroll liabilities clear each month. When they have not cleared for a quarter or more, nobody can tell from QuickBooks what was deposited, what is late, and what a 941-X should correct. Cleanup reconciles the payroll accounts to the provider’s register and the bank, month by month, so the preparer is answering the IRS from records instead of estimates.
