When Is Form 941 Due? Quarterly Dates, Deposits, and Penalties

Form 941 due dates are April 30, July 31, October 31, and January 31, one for each calendar quarter. Those are the dates the return itself is due. The taxes the return reports have to be deposited on a separate, more frequent schedule, and that’s where most employers get into trouble.

The Four Quarterly Deadlines

Each Form 941 covers one calendar quarter and is due the last day of the month after the quarter ends:

Q1 (January–March): April 30
Q2 (April–June): July 31
Q3 (July–September): October 31
Q4 (October–December): January 31 of the following year

When a due date lands on a Saturday, Sunday, or legal holiday, it shifts to the next business day.¹ That matters for two 2026 quarters. October 31, 2026 falls on a Saturday, so the Q3 return is due Monday, November 2, 2026. January 31, 2027 falls on a Sunday, so Q4 is due Monday, February 1, 2027. The April 30 and July 31 deadlines land on weekdays and don’t move.

Ten Extra Days if Your Deposits Were on Time

If you deposited every dollar of tax on time throughout the quarter, you get an extra 10 calendar days past the standard due date to file Form 941.² The extension applies automatically. Miss even one deposit during the quarter and it disappears, leaving you with the standard date.

Deposit Deadlines Are Separate

Filing Form 941 is the reporting side. The taxes have to be deposited much more often, and your schedule depends on how much employment tax you reported during a lookback period running from July 1 of the second preceding year through June 30 of the prior year.³

Monthly Depositors

If your total employment taxes during the lookback period were $50,000 or less, you’re a monthly depositor. Taxes accumulated during a calendar month are due by the 15th of the following month.⁴ March payroll taxes, for example, are due April 15.

Semi-Weekly Depositors

If your lookback liability exceeded $50,000, you deposit on a semi-weekly schedule keyed to your paydays.⁴

Payday on Wednesday, Thursday, or Friday: deposit due the following Wednesday.
Payday on Saturday, Sunday, Monday, or Tuesday: deposit due the following Friday.

The name is a little misleading. You don’t automatically deposit twice a week; you may, depending on when your paydays fall.

The $100,000 Next-Day Rule

Whatever your regular schedule, if you accumulate $100,000 or more in tax liability on any single day, the full amount is due by the close of the next business day.³ Hitting that threshold also automatically reclassifies you as a semi-weekly depositor for the rest of the calendar year and the entire following year.⁵

All federal employment tax deposits must be made electronically.⁶ You can’t mail a check. If you’re new in business, enroll in EFTPS early: activation can take a week or more because the IRS mails a PIN to your business address, and missing a deposit because your enrollment wasn’t finished doesn’t excuse the penalty.

When You File a Different Form Instead

Not every employer follows the quarterly 941 calendar.

Agricultural employers report wages for farm employees on Form 943, an annual return.²
Very small employers with $1,000 or less in annual employment tax liability may file Form 944 once a year, but only if the IRS notifies them they’re eligible. You can request the switch in writing postmarked by March 15 or by calling 800-829-0115 by April 1.⁷
Household employers report employment taxes on Schedule H with their personal return, not on Form 941.

Seasonal Employers and Final Returns

If you only pay wages during part of the year, check the seasonal employer box in Part 3 of every Form 941 you actually file. Otherwise the IRS expects returns for the quiet quarters and will send notices when nothing arrives.⁸ The box has to be checked each quarter, not just once.

When a business closes or permanently stops paying wages, file a final Form 941 for the last quarter in which wages were paid and check the final-return box. That closes out your filing obligation.⁹ Skip it and the IRS will keep expecting quarterly returns.

What Missing a Deadline Costs

Late filing and late deposits are penalized separately. You can owe both at once.

Late Filing

The failure-to-file penalty is 5% of the unpaid tax for each month or partial month the return is late, capped at 25%.¹⁰ A separate failure-to-pay penalty of 0.5% per month runs on any unpaid balance.¹¹ File on time even if you can’t pay in full; the filing penalty is ten times heavier than the payment one.

Late Deposits

Deposit penalties escalate with how late the money arrives:¹²

1–5 calendar days late: 2%
6–15 calendar days late: 5%
16 or more days late: 10%
More than 10 days after an IRS notice demanding payment: 15%

Interest runs from the original due date. Each missed deposit generates its own penalty, so several short deposits in a single quarter can stack.

The IRS can abate these penalties for reasonable cause, meaning you exercised ordinary business care and prudence but still couldn’t comply. A fire, serious illness, or a payroll provider that failed can qualify. Forgetting or not knowing the rule generally doesn’t.

Deadlines for Correcting a Past Return

Errors on a filed Form 941 are fixed with Form 941-X, filed separately for each quarter being corrected.¹³ For overreported taxes, the deadline is three years from the date the original return was filed or two years from the date the tax was paid, whichever is later. For underreported taxes, it’s three years from the original filing date, and the additional tax is due when you submit the 941-X.¹⁴
