Form 941 Due Dates 2026: Q3 Is Due November 2, Q4 Is Due February 1, 2027, and How to File
Form 941 is the quarterly return that reports the wages you paid, the federal income tax you withheld and both halves of Social Security and Medicare tax. It's due four times a year, and in 2026 two of those dates land on a weekend, which is why so many calendars online are off by a day or two.
Below is every date from the last 2025 return through the first 2027 return, the rule behind the extra 10 days, and the ways you can file. Keep in mind that the return is only half the job. Payroll taxes are deposited during the quarter on your monthly or semiweekly deposit schedule, which has its own deadlines.
Form 941 due dates 2026 are April 30, July 31, November 2 and, for the fourth quarter, February 1, 2027, because October 31 and January 31 fall on weekends. If you made every deposit for the quarter on time and in full, you can file by the 10th of the second month: November 10, 2026 for Q3 and February 10, 2027 for Q4.
Form 941 due dates 2026 at a glance
The IRS rule is simple: the return is due on the last day of the month after the quarter ends, and a due date on a Saturday, Sunday or legal holiday moves to the next business day. Here's how that plays out from the last 2025 return to the first 2027 return.
| Return | Wages paid | Due date | If every deposit was on time and in full |
|---|---|---|---|
| Q4 2025 | Oct 1 to Dec 31, 2025 | Mon, Feb 2, 2026 (Jan 31 was a Saturday) | Tue, Feb 10, 2026 |
| Q1 2026 | Jan 1 to Mar 31, 2026 | Thu, Apr 30, 2026 | Mon, May 11, 2026 (May 10 was a Sunday) |
| Q2 2026 | Apr 1 to Jun 30, 2026 | Fri, Jul 31, 2026 | Mon, Aug 10, 2026 |
| Q3 2026 | Jul 1 to Sep 30, 2026 | Mon, Nov 2, 2026 (Oct 31 is a Saturday) | Tue, Nov 10, 2026 |
| Q4 2026 | Oct 1 to Dec 31, 2026 | Mon, Feb 1, 2027 (Jan 31 is a Sunday) | Wed, Feb 10, 2027 |
| Q1 2027 | Jan 1 to Mar 31, 2027 | Fri, Apr 30, 2027 | Mon, May 10, 2027 |

A return mailed through the U.S. Postal Service counts as on time if it's properly addressed, has enough postage and is postmarked by the due date. An IRS-designated private delivery service sent by the due date counts too. Otherwise the IRS treats the return as filed when it arrives.
What's due now: the Q3 2026 return
The third-quarter return covers wages paid from July 1 through September 30, 2026. It's due Monday, November 2, 2026, or Tuesday, November 10, 2026 if every Q3 deposit went in on time and in full. A few Q3 details trip people up:
- Line 1 counts employees paid for the pay period that includes September 12, not your headcount on September 30.
- Use the March 2026 revision of Form 941. The IRS expects it for the second, third and fourth quarters of 2026.
- The last Q3 deposits were due in October: by October 15, 2026 for monthly depositors' September wages, and on the semiweekly dates for September paydays.
- Paid nothing in Q3? You may still owe a zero return. See when you still file with no payroll.
How the extra 10 days really work
The IRS lets you file by the 10th day of the second month after the quarter if you made timely deposits in full payment of that quarter's taxes. People call it a "10-day extension," but three details matter.
The extra time is tied to deposits. If you're paying the quarter's tax with the return because it's under the small-liability limit, plan on the standard date. And if you're not sure every deposit landed on time, file by the standard date; filing early costs nothing.
Disaster postponements can move the Q3 date to February 1, 2027
When the IRS announces disaster relief, it can postpone quarterly payroll returns for businesses in the covered area. For example, its Indiana announcement IN-2026-01 (issued September 2, 2026 and updated October 8, 2026) moves quarterly payroll returns normally due November 2, 2026 to February 1, 2027 for the listed counties. Several other 2026 announcements also postpone deadlines to February 1, 2027.
In the Indiana relief, deposit penalties were waived only for deposits due August 11 through August 25, 2026 that were made by August 26, 2026. Deposits after that window followed the normal schedule. Check whether your county is listed on the IRS tax relief in disaster situations page and read your announcement's payroll lines before relying on it.
Filing deadline vs deposit deadline
The dates above are for the return. Deposits of withheld income tax and Social Security and Medicare tax are due much sooner, on one of two schedules set by your lookback period:
- Monthly depositors deposit each month's taxes by the 15th of the next month.
- Semiweekly depositors deposit by the Wednesday or Friday after each payday.
- Anyone who piles up $100,000 or more in tax on a single day in 2026 deposits by the next business day.
Example: a monthly depositor's September 2026 payroll taxes were due October 15, 2026. Filing the Q3 return on time on November 2 doesn't fix a deposit made on October 30; the deposit is still 15 days late. The full calendars, the 2027 lookback and the payment methods are in our guide to the 941 deposit schedule and how to pay.
How to file Form 941: e-file, paper or a professional
You can file Form 941 yourself, on paper or electronically, or have someone file it for you. The March 2026 instructions don't require e-filing, but you file only once for each quarter: if you e-file, don't also mail a paper copy.
| Method | What you need | Lead time and cost | Proof it was filed |
|---|---|---|---|
| E-file it yourself | 94x e-file software from a provider on the IRS's approved list, and a signature: a 94x Online Signature PIN, or a scanned Form 8453-EMP if your software accepts it | Allow at least 45 days to get a PIN. Software fees vary. | IRS acknowledgement, usually within 24 hours |
| Tax professional | An authorized IRS e-file provider (the IRS has a locator) | Their fee; they handle the signature process | Their acknowledgement record |
| Payroll provider | A provider that files as your reporting agent, usually with your signed Form 8655 | Their fee; set up before the quarter ends | Provider filing report; you're still responsible |
| Paper return | A completed, signed March 2026 Form 941 mailed to the IRS address for your state | Postage; allow mailing time before the due date | USPS postmark or private delivery service record |

Mailing addresses depend on your state and on whether a payment is enclosed, and they change from time to time. Our guide to where to mail Form 941 lists the current addresses. If you need a blank return, the fillable March 2026 Form 941 PDF is on IRS.gov.
You can prepare your Form 941 from your payroll totals, preview it, then print, sign and mail it. Semiweekly depositors can add Schedule B the same way. ePaystubs prepares the forms; it doesn't e-file them or make deposits for you.
Who can sign Form 941
An unsigned return can delay processing, so make sure the right person signs page 2 (Part 5).
| Business type | Who signs |
|---|---|
| Sole proprietorship | The owner |
| Corporation, or an LLC taxed as one | The president, vice president or another authorized principal officer |
| Partnership, or an LLC taxed as one | An authorized partner, member or officer who knows the business's affairs |
| Single-member LLC treated as disregarded | The owner or an authorized principal officer |
| Trust or estate | The fiduciary |

An agent can sign with a valid power of attorney on file, and corporate officers can use a rubber stamp or software signature under Rev. Proc. 2005-39. A paid preparer who isn't your employee also signs the Paid Preparer section.
Before you file: the quarter-end checklist
Missed a deadline or filed the wrong return?
File the late return as soon as you can. Under the 2026 rules, the failure-to-file penalty generally runs 5% of the unpaid tax for each month or part of a month the return is late, up to 25%, so waiting adds cost even when you can't pay in full yet. Late deposits are penalized separately.
- Late return, late deposits or an IRS notice: see Form 941 penalties, interest and relief.
- Filed with a mistake: don't send a second original. Correct Form 941 with Form 941-X instead.
- No payroll this quarter, seasonal or closing: see zero, seasonal and final Form 941.
- Not sure where the paper return goes: check the Form 941 mailing addresses.
Five date claims you'll see online, checked
| What you might read | What the IRS rule gives for 2026 |
|---|---|
| "Q3 Form 941 is due October 31, 2026." | October 31 is a Saturday, so it's due Monday, November 2, 2026. |
| "The Q1 extended date was May 10, 2026." | May 10 was a Sunday, so the date was Monday, May 11, 2026. |
| "You get 10 extra days after the due date." | It's the 10th of the second month: November 10, not November 12, for Q3. |
| "You have to request the 10-day extension." | There's no request. It applies only if every deposit was on time and in full. |
| "Check line 18 when you file a zero return." | Line 18 is for seasonal employers. A zero return leaves it blank unless you're seasonal. |
Frequently Asked Questions
Monday, November 2, 2026, because October 31 falls on a Saturday. If every Q3 deposit was made on time and in full, you can file by Tuesday, November 10, 2026. Businesses in some IRS disaster areas have until February 1, 2027.
There's no extension you can request. The only extra time is automatic: if you deposited all of the quarter's taxes on time and in full, you can file by the 10th of the second month after the quarter. IRS disaster relief can also postpone the due date.
Yes. You can mail a signed paper return or e-file through software from an IRS-listed 94x provider, signing with a 94x Online Signature PIN or Form 8453-EMP. The PIN can take 45 days or more to arrive, so apply well before a deadline if you plan to e-file.
The March 2026 Form 941 instructions don't require it, so a paper return mailed to the right address is still accepted. E-filing gives you an IRS acknowledgement, usually within 24 hours. Whichever you choose, file only one original return for each quarter.
If tax is unpaid, the IRS generally charges a 2026 failure-to-file penalty of 5% of that tax per month or part of a month, up to 25%, plus interest. Late deposits draw their own penalty. Filing as soon as possible limits the monthly charge.
Usually only for a short window. In the 2026 Indiana relief, for example, the Q3 return moved to February 1, 2027, but deposit penalties were waived only for deposits due August 11 through 25 that were made by August 26.
