Form 941 Penalties in 2026: Late Filing, Late Deposits, Interest and IRS Notices
Form 941 penalties come in three separate pieces, and most employers who get a notice owe more than one. There's a penalty for filing the return late, a penalty for depositing the tax late, and a penalty for paying late, plus interest on top. Each one is figured differently, so a return that's a week late can cost nothing while a deposit that's a week late costs 5% under the 2026 rules.
If you're working against the third-quarter 2026 deadline (Monday, November 2, 2026), the dates that start these clocks are in our guide to Form 941 due dates for 2026. This page covers what each penalty costs, a worked example in dollars, the IRS notices you might see, and every way to get a penalty removed, including the automatic relief the IRS started rolling out in summer 2026.
The Form 941 late filing penalty is 5% of the unpaid tax for each month or part of a month the return is late, up to 25%. Late deposits draw a separate 2%, 5%, 10% or 15% penalty, and unpaid tax adds a 0.5% monthly late-payment penalty plus interest, 7% a year for Q4 2026.
| Penalty | What triggers it | 2026 rate | Cap |
|---|---|---|---|
| Failure to file (late return) | Form 941 filed after its due date | 5% of the tax still unpaid, per month or part of a month | 25% |
| Failure to deposit (late deposit) | Payroll tax deposit late, short, or not made electronically | 2%, 5%, 10% or 15%, depending on how late | 15% |
| Failure to pay (late payment) | Tax shown on the return not paid by the due date | 0.5% per month or part of a month; 1% after a levy notice | 25% |
| Interest | Any unpaid tax or penalty | 7% a year in Q4 2026, compounded daily | None |
| "Averaged" deposit penalty | Line 16 or Schedule B missing or filled in wrong | 2% to 10% | 10% |
| Trust fund recovery penalty | Withheld taxes willfully not paid over | 100% of the unpaid trust fund tax, charged to responsible people personally | 100% |

Form 941 late filing penalty: 5% a month, up to 25%
The failure-to-file penalty is 5% of the tax due for each month or part of a month Form 941 is late, and it stops growing at 25% after five months. "Tax due" means the tax the return should show minus anything you already paid on time, so for a Form 941 it's essentially line 12 minus your timely deposits. The IRS spells this out on its failure-to-file penalty page (updated October 5, 2026).
Part of a month counts as a full month. A third-quarter 2026 return due November 2 that's filed on November 3 is one month late; filed on December 3, it's two. There's no general extension for Form 941, though employers who deposited every dollar on time get extra days to file, which our due-dates guide explains under when the extra 10 days applies.
Filed late, but every deposit was on time?
Then the 2026 late-filing penalty is 5% of zero. If your deposits covered the full line 12 amount on time, there's no unpaid tax for the 5% to apply to, so a late return on its own costs nothing in failure-to-file penalty. That doesn't mean you can skip the return. The IRS still expects it, and a missing return triggers a CP259 notice, which we cover in the notices section below.
What about the $525 minimum penalty?
You may see a $525 minimum late-filing penalty quoted for 2026. On the IRS page, that minimum (the smaller of $525 or 100% of the tax, for returns more than 60 days late and due after December 31, 2025) is listed under income tax returns, Forms 1040 and 1120. It isn't listed for employment tax returns like Form 941, so don't assume a $525 floor applies to a late 941.
Late deposit penalty: 2%, 5%, 10% or 15%
The failure-to-deposit penalty is usually the biggest one, and it's separate from the late-filing penalty. It's charged on the amount that wasn't deposited on time, in full, or electronically, and it's counted in calendar days from the date each deposit was due. The tiers below come from IRS Publication 15 (2026), and they don't add together: you pay one rate per late amount.
| Deposit made | Penalty on the late amount (2026) |
|---|---|
| 1 to 5 calendar days late | 2% |
| 6 to 15 calendar days late | 5% |
| 16 or more days late, but before 10 days after the IRS's first notice | 10% |
| Paid directly to the IRS or with the return instead of deposited, when a deposit was required | 10% |
| Still unpaid more than 10 days after the first IRS notice, or on the day you receive a demand for immediate payment, whichever is earlier | 15% |
Source: IRS Publication 15 (2026), section 11; IRS failure-to-deposit penalty page (February 24, 2026).
Your deposit due dates depend on whether you're a monthly or semiweekly depositor, so check your monthly or semiweekly deposit due dates before you count the days.
Mailing a check with the return can cost 10%
This is the penalty many small employers don't see coming. If you were required to deposit and instead sent the money with Form 941 or straight to the IRS, Publication 15 (2026) charges 10% on that amount, even if it arrived before the return's due date. The exception is when you qualify to pay with the return, generally when line 12 is under $2,500 for the current or prior quarter and you didn't trigger the $100,000 next-day deposit rule.
Why one missed deposit can make the next ones late
The IRS applies each deposit to the most recent liability in the quarter first. Publication 15 (2026) gives this example: a business owes a $1,000 deposit on April 15 and a $1,500 deposit on May 15, skips April, then deposits $2,000 on May 15. The IRS puts $1,500 toward May and only $500 toward April, so $500 of April's deposit stays undeposited and keeps aging into the higher tiers.
You can fight that cascade. After you receive a failure-to-deposit penalty notice, you have 90 days from the date of the notice to tell the IRS how to apply your deposits in the way that produces the smallest penalty. Follow the instructions on the notice; the rules are in Revenue Procedure 2001-58, which Publication 15 references.
Former Form 944 filers get a January break
If you filed Form 944 last year and switched to Form 941 this year, Publication 15 (2026) says the deposit penalty won't apply to a late deposit of January's taxes as long as you deposit them in full by March 15.
The averaged deposit penalty (and how to avoid it)
When your line 12 total is $2,500 or more, the IRS needs to know when each liability arose to check whether your deposits were on time. If it can't tell, it spreads your quarter's tax evenly across the quarter and charges an "averaged" failure-to-deposit penalty of 2% to 10%, per Publication 15 (2026). Deposits you actually made on time can end up looking late.
It applies when a monthly schedule depositor doesn't fill in line 16 properly, or when a semiweekly schedule depositor fills in line 16 instead of Schedule B, leaves Schedule B off, or enters deposits instead of liabilities on it. Before you file:
Late payment penalty and interest on Form 941
If tax shown on the return isn't paid by the due date, the failure-to-pay penalty adds 0.5% of the unpaid amount for each month or part of a month, up to 25%, according to the IRS failure-to-pay penalty page (updated June 5, 2026). The rate rises to 1% a month if the tax still isn't paid 10 days after the IRS sends a notice of intent to levy.
When the late-filing and late-payment penalties both apply in the same month, the IRS reduces the 5% filing penalty by the 0.5% payment penalty. In practice that's 4.5% plus 0.5%, so a late, unpaid return costs 5% a month in 2026 for the first five months, not 5.5%.
Interest in 2026
Interest runs on unpaid tax and on penalties until the balance is paid, and it's compounded daily. The IRS sets the rate each quarter; these are the 2026 underpayment rates from the IRS quarterly interest rates page:
| 2026 quarter | Underpayment interest rate |
|---|---|
| January to March 2026 | 7% |
| April to June 2026 | 6% |
| July to September 2026 | 7% |
| October to December 2026 | 7% |
One rule worth knowing before you ask for relief: the IRS says it can't remove or reduce interest unless the related penalty is removed or reduced. Getting the penalty abated is what takes the interest on it away.
Worked example: what one missed $8,000 deposit costs
Here's how the pieces stack for a third-quarter 2026 return. A monthly depositor owes $24,000 for the quarter (line 12). July's and August's $8,000 deposits go in on time, but September's $8,000, due October 15, 2026, is missed. The employer files Form 941 and pays the $8,000 on December 20, 2026, with no IRS notice received first.
| Charge | How it's figured | Amount |
|---|---|---|
| Late deposit penalty | $8,000 paid 66 days after October 15, 2026 (also paid with the return): 10% | $800 |
| Late filing penalty | Return due November 2, filed December 20: two months or part months at 4.5% (5% reduced by 0.5%) on $8,000 | $720 |
| Late payment penalty | Two months or part months at 0.5% on $8,000 | $80 |
| Interest on the tax (estimate) | 7% Q4 2026 rate, compounded daily, for the 48 days from November 2 to December 20 on $8,000 | About $74 |
| Total | Before any interest on the penalties themselves | About $1,674 |

That's about 21% of the missed deposit, and most of it came from timing. Had the employer filed on time on November 2, 2026 and paid the $8,000 that day, the late filing and late payment penalties would have been zero, and the bill would have been the $800 deposit penalty plus a little interest.
The trust fund recovery penalty: when it becomes personal
If income tax withheld from paychecks and the employees' share of Social Security and Medicare aren't paid over, the IRS can assess the trust fund recovery penalty against individuals. It equals 100% of the unpaid trust fund tax, per IRS guidance updated in October 2026, and the IRS can collect it from personal assets.
According to the IRS trust fund recovery penalty page (updated October 11, 2026), it can apply to anyone who's responsible for collecting or paying these taxes and willfully fails to do so: officers, partners, directors, shareholders, payroll providers and others with authority over the money. Paying other bills while payroll taxes go unpaid is a sign of willfulness, and the penalty can apply even while the business keeps operating.
The IRS may interview you about your role, then send a letter proposing the assessment. You have 60 days from that letter to appeal (75 days if it's addressed to you outside the U.S.). If you get one, talk to a tax professional before you respond.
IRS notices about Form 941 penalties
Penalties usually arrive by notice, and the notice number tells you what the IRS thinks happened. These are the ones Form 941 filers see most, with what to do about each:
| Notice | What it means | What to do |
|---|---|---|
| CP259 | The IRS has no record of a Form 941 it expected for the listed quarter | File the return now, or use the response form to explain you weren't required to file. If you filed within the last four weeks, the IRS says you can disregard it |
| CP136 | Sets next year's deposit schedule from your lookback period; it isn't a penalty notice | Check the amounts against your records. A $0 quarter on it means the IRS has no Form 941 on file for that quarter |
| CP210 or CP220 | The IRS changed your return and shows the new balance or penalty; the IRS cites CP220 as an example of a first notice | Compare it with your records. Pay or dispute quickly, because the 15% deposit tier can apply 10 days after the first notice |
| CP504J | The IRS's example of a notice demanding immediate payment | Pay or call right away; the 15% deposit tier can apply from the day you receive it |
| Letter proposing the trust fund recovery penalty | The IRS believes you're personally responsible for unpaid withheld taxes | You have 60 days to appeal; get professional help before responding |
Sources: IRS Understanding your CP259 notice (August 11, 2026), IRS CP136 page (December 16, 2025), IRS failure-to-deposit penalty page, IRS trust fund recovery penalty page.
If a notice comes from a mistake on the return itself, such as underreported wages, the fix is to correct the return with Form 941-X rather than filing a second Form 941.
How to get Form 941 penalties removed
You've got more options than most employers realize. The IRS has administrative waivers, Publication 15 (2026) lists deposit-specific waivers, and the deposit designation rule can shrink a penalty without anyone waiving anything. Here's how they compare:
| Relief | Who qualifies | How you get it |
|---|---|---|
| Automatic Exemption from Penalty (AEP), starting summer 2026 | Filers of Forms 940, 941, 943, 944, 945 and others with a clean three-year history (12 consecutive quarters for quarterly filers), whose deposit penalty wasn't waived four or more times and wasn't for avoiding EFTPS | Automatic when the original return finishes processing. Covers late filing, late payment and late deposit penalties |
| First Time Abate (FTA) | The same clean-history test | Call the number on your notice, or send a written statement or Form 843. You don't have to name FTA |
| First-time depositor waiver | You filed the return on time, the late deposit was your first required one or your first after a deposit-frequency change, and the business's net worth is $7 million or less with 500 or fewer employees | Ask for it in response to the deposit penalty notice |
| First EFT mistake waiver | The first time you were required to deposit, you inadvertently sent the payment to the IRS instead of depositing it electronically | Ask for it in response to the notice |
| Reasonable cause | You acted in good faith and couldn't comply because of facts outside your control | Explain in writing with supporting records |
| Deposit designation | You received a failure-to-deposit penalty notice | Within 90 days of the notice, tell the IRS how to apply your deposits to minimize the penalty |

The IRS relief page is inconsistent about whether 2026 quarterly returns fall under the new automatic relief or still under First Time Abate. If a 2026 Form 941 penalty shows up on a notice and your history is clean, call the number on the notice and ask; the relief is the same, only the route differs.
Whatever route you use, you'll need records: deposit confirmations, the dates you paid employees, and anything showing why a deposit or filing was late. Our payroll records guide explains how long to keep the records that prove reasonable cause.
Missed a Form 941 deadline? How to stop penalties from growing
In 2026 the late-filing penalty adds another 5% every month you wait until it hits 25%, and interest keeps running, so the cheapest move is usually to act now rather than wait for a notice.
You can prepare the overdue Form 941 from your payroll totals, preview it, then print, sign and mail it. The generator fills out the form; it doesn't file it with the IRS or fix a penalty for you.
Frequently Asked Questions
You can file a late Form 941 at any time, and you should file as soon as you can. In 2026 the late-filing penalty is 5% of the unpaid tax per month or part of a month, stopping at 25%, but interest and the late-payment penalty keep running until you pay.
The IRS sends a CP259 notice saying it has no record of the return, and 2026 penalties build on any unpaid tax: 5% a month for filing late, 0.5% a month for paying late, plus interest. Unpaid withheld taxes can also bring the trust fund recovery penalty.
Not usually. The 2026 penalty is 5% of the tax that's still unpaid, so if your deposits covered the quarter in full and on time, it works out to zero. You still have to file, and a missing return can trigger a CP259 notice.
Under Publication 15 (2026), it's 2% if the deposit is 1 to 5 days late, 5% for 6 to 15 days, and 10% after that. Paying with the return when a deposit was required also costs 10%, and 15% applies 10 days after the first IRS notice.
Yes. Employers with a clean three-year history may get automatic relief or First Time Abate, and Publication 15 lists waivers for a first required deposit and for a first payment mistakenly sent to the IRS. Reasonable cause and the 90-day deposit designation rule can also reduce or remove penalties.
Yes. Interest runs on unpaid tax and on penalties until the balance is paid, compounded daily, at 7% a year for the fourth quarter of 2026. The IRS says it can't remove interest unless the penalty that caused it is removed or reduced.
