Form 941 for the third quarter of 2026 (wages paid July 1 through September 30) is due Monday, November 2, 2026, because the normal October 31 date falls on a Saturday. Employers that deposited and paid all required taxes on time and in full may file by November 10. Accounting teams should confirm deposit status this week and file or calendar the correct deadline to avoid failure-to-file penalties.
The IRS Form 941 quarterly employer tax return for the third quarter of 2026 is due on Monday, November 2, 2026. The standard due date is the last day of the month following the quarter. October 31, 2026, falls on a Saturday, so the deadline moves to the next business day. Employers that made every federal tax deposit for the quarter on time and in full receive an extra 10 days and may file by Tuesday, November 10, 2026.
This is operational guidance based on published IRS due-date rules. It is not tax advice. Confirm specific facts with your payroll provider or tax advisor.
What changed?
Nothing in the underlying rule. The Q3 2026 Form 941 filing deadline simply lands on November 2 because October 31 is a Saturday.
When?
Standard deadline: Monday, November 2, 2026. Extended deadline if all deposits were timely and in full: Tuesday, November 10, 2026.
Who is affected?
All employers that paid wages in July–September 2026 and are required to file Form 941.
What to do this week?
Confirm with payroll whether every deposit for the quarter was made on time and in full. File or schedule the return for the applicable deadline and retain proof of filing.
What is Form 941 and what does Q3 2026 cover?
Form 941 is the Employer’s Quarterly Federal Tax Return. It reports federal income tax withheld from employees, Social Security and Medicare taxes (both employee and employer shares), and reconciles those amounts against deposits made during the quarter. The third quarter covers wages paid from July 1 through September 30, 2026. The form is filed by most employers that pay wages subject to federal employment taxes; certain agricultural, household, or very small employers may use different forms or schedules.
Why is the deadline November 2 instead of October 31?
IRS instructions state that Form 941 is due on the last day of the month after the quarter ends. For Q3 that is October 31. When a due date falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. In 2026 October 31 is a Saturday, so the filing date is Monday, November 2. Multiple tax-service summaries published in late October and early November 2026 confirm this weekend rule application. The same rule applied to the October 31 FUTA deposit threshold for employers that owed more than $500 for the quarter.
Who gets the November 10 extended date?
Employers that deposited and paid all required taxes on time and in full for the quarter may file by the 10th day of the second month after the quarter ends. For Q3 2026 that date is November 10. The extension applies only to filing, not to the underlying deposit deadlines. Monthly depositors still face their own deposit calendar (for example, October wages are generally due by November 16 because the 15th falls on a Sunday). Next-day depositors continue to follow the $100,000 next-day rule regardless of the Form 941 filing date.
The IRS has long applied this 10-day filing extension when deposits are current. It is not a new relief measure for 2026; it is the ordinary rule restated in the Form 941 instructions and in annual tax calendars.
What should accounting teams do this week?
Pull the Q3 deposit history from the payroll system or tax provider. Verify that every deposit was made by the applicable due date and in the correct amount. If the on-time condition is met, calendar November 10. If any deposit was late or short, treat November 2 as the hard deadline. E-file through approved software or a payroll provider, or paper-file with a timely postmark. Keep the acknowledgment or certified-mail receipt. Confirm that the return reflects any credits or adjustments for the quarter and that the deposit reconciliation on the form matches the bank records.
What happens if the return is late?
Failure-to-file and failure-to-deposit penalties can apply. The failure-to-file penalty is generally 5 percent of the unpaid tax for each month or part of a month the return is late, up to 25 percent. Deposit penalties scale with the number of days late. Interest also accrues on underpayments. Accurate, timely filing avoids these costs and keeps the account in good standing for later year-end forms such as W-2s and the annual Form 940. Trust-fund recovery penalty exposure can also arise for responsible persons if withheld taxes are not deposited.
What to watch next
Q4 2026 Form 941 will be due February 1, 2027 (January 31 is a Sunday), or February 10 if all deposits were timely. Year-end Form W-2 and Form 1099 deadlines follow in January. Accounting teams should also confirm that any state unemployment or withholding returns follow their own calendars. Monitor IRS announcements for any late-year relief, though none has been indicated for the ordinary Q3 filing date.
Is Form 941 for Q3 2026 really due November 2?
Yes. The normal October 31 date falls on a Saturday in 2026, so the deadline moves to the next business day, Monday, November 2.
Can some employers file later?
Yes. If every required deposit for the quarter was made on time and in full, the filing deadline is November 10, 2026.
Does the filing extension change deposit due dates?
No. Deposit rules are separate. Monthly and next-day depositors must still meet their deposit calendars.
What wages are reported on the Q3 Form 941?
Wages paid from July 1 through September 30, 2026.
What is the failure-to-file penalty rate?
Generally 5 percent of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25 percent.
