United States · guideForm 941 Quarterly Deadlines and What Feeds Them
The short answer
Form 941 (Employer's Quarterly Federal Tax Return) is due April 30, July 31, October 31, and January 31 — the last day of the month after each quarter ends, rolled to the next business day when that date falls on a weekend or legal holiday. An employer who deposited the full quarter's tax liability on time gets an automatic 10 additional calendar days to file. The return and the deposits run on separate clocks: filing Form 941 does not pay the tax, and paying the tax does not file the return. Both obligations depend on a payroll general ledger that reconciles to the wage and withholding figures reported on the form before anyone signs it.
Key facts — verified dates on each
The four quarter-ends and their base due dates
Form 941 reports wages, tips, federal income tax withheld, and both the employer and employee shares of Social Security and Medicare tax for one calendar quarter. It is filed separately for each of the four quarters, and the base due date is always the last day of the month immediately following the quarter's close.
For calendar year 2026, that puts Q1 (January–March) due April 30, 2026, and Q2 (April–June) due July 31, 2026 — both ordinary weekdays with no shift. Q3 (July–September) ends September 30, and its normal due date of October 31, 2026 falls on a Saturday, so the IRS return date shifts to the next business day, Monday, November 2, 2026. Q4 (October–December) ends December 31, and its normal due date of January 31, 2027 falls on a Sunday, shifting the due date to the next business day, Monday, February 1, 2027.
The weekend-and-holiday roll-forward is a standing IRS rule, not a one-off: whenever a due date lands on a Saturday, Sunday, or legal holiday, the return is considered timely if filed by the next business day. Because that shift depends on the specific calendar year, the mechanism matters more than memorizing any single year's dates — confirm the current quarter's exact due date against the IRS calendar or Form 941 instructions before relying on it.
The 10-day extension for on-time depositors
A separate rule extends the filing deadline — not the payment deadline — for employers who kept up with deposits. If an employer deposited the entire tax liability for the quarter in full and on time under its deposit schedule, it may file Form 941 by the 10th day of the second month following the end of the quarter, rather than the last day of the first month.
This is not a discretionary extension the employer requests; it applies automatically to any filer who qualifies. But qualification is strict: partial compliance does not count. An employer who deposited 90% of what it owed on time, or missed a single deposit date, does not receive the extra 10 days for that quarter — the standard end-of-month deadline governs instead.
Because the extension turns on deposit history rather than a form or election, the only way to know whether it applies is to check the deposit record against the required schedule for the quarter before assuming the later date is available.
Deposits and the return run on different clocks
Form 941 is a reconciliation of tax that should already have been deposited during the quarter, not the mechanism for paying it. Employers deposit federal income tax withholding and both shares of FICA tax on a monthly or semiweekly schedule determined by the total tax reported during a prior 12-month lookback period — a schedule that operates independently of the quarterly filing deadline.
This separation is where the most common payroll errors occur: a business that pays its full liability along with the 941 filing, instead of on the deposit schedule that ran throughout the quarter, has still missed every deposit due date during that quarter — even though the return itself and its full payment arrive on time. Filing the form does not cure a deposit that was already late.
The two obligations also carry separate penalty structures, covered below, which is another reason to treat "the return is filed" and "the deposits were timely" as two different questions that both need affirmative answers.
What happens when either deadline is missed
A late-filed Form 941 is subject to a failure-to-file penalty under Internal Revenue Code section 6651(a)(1): a percentage of the unpaid tax for each month or partial month the return is late, up to a stated maximum. Reasonable-cause relief exists under the same framework but requires a facts-and-circumstances case the employer (with its adviser) makes to the IRS — it is not automatic.
A late or short deposit is penalized separately under the failure-to-deposit rules, on a tiered scale that increases with how late the deposit is: a lower rate for deposits made within the first few days after the due date, rising through intermediate tiers, up to the highest rate for amounts still unpaid well after an IRS notice. The exact rate depends entirely on which band the lateness falls into — see figures below.
Both penalty regimes are calculated on the unpaid or untimely amount, not the full quarterly liability, and interest accrues separately. Because rates and thresholds are set by statute and IRS guidance that can be updated, the specific figures below carry a verification date rather than being treated as permanently fixed.
Tying the general ledger before the filer files
Form 941 asks for exact totals: total wages and tips subject to withholding, federal income tax withheld, taxable Social Security and Medicare wages, and the tax calculated on each. Every one of those figures should trace back to the payroll register and, from there, to the general ledger accounts where wage expense, withholding liabilities, and employer payroll tax expense are posted.
A bookkeeping process that reconciles payroll clearing accounts each pay period — confirming that what left the bank account, what was recorded as expense, and what was reported to the payroll provider all agree — gives the return preparer a clean number to start from instead of a reconstruction project during filing week. Discrepancies caught mid-quarter (a missed bonus run, a benefits deduction booked to the wrong account, a contractor misclassified as an employee in the ledger) are far cheaper to fix before the quarter closes than after a 941 has already been filed and needs amending on Form 941-X.
CapEasy's bookkeeping support keeps payroll clearing accounts reconciled on a recurring cadence so the numbers behind a 941 filing are already tied out when the filer needs them; the actual preparation, signing, and filing of the return is done by the employer or its payroll/tax provider.

Questions on this
When is Form 941 due each quarter?
By the last day of the month following the quarter's end: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4. Whenever that date falls on a Saturday, Sunday, or legal holiday, the return is timely if filed on the next business day — which is why some quarters show a slightly later date on the calendar.
What is the 10-day extension and who qualifies?
An employer that deposited its entire quarterly tax liability in full and on time gets an automatic 10 extra calendar days beyond the standard due date to file. It requires no separate election or form. It also requires strict compliance — a partial or slightly late deposit removes eligibility for that quarter, and the standard end-of-month due date applies instead.
Does filing Form 941 satisfy the deposit requirement too?
No. Deposits of withheld income tax and FICA tax are due on a monthly or semiweekly schedule set independently of the quarterly filing date. Form 941 reports and reconciles what should already have been deposited; it is not itself a payment mechanism, and submitting payment with the return does not retroactively make earlier deposits timely.
What determines whether a business deposits monthly or semiweekly?
The deposit schedule is set by a lookback period — generally the total employment tax reported during a prior 12-month window — and is fixed for the entire calendar year regardless of what happens during the current quarter. Because the lookback figure changes year to year, the current year's assigned schedule is not always the same as the prior year's.
What happens if Form 941 is filed late?
A failure-to-file penalty applies under IRC section 6651(a)(1): a percentage of the unpaid tax for each month or partial month late, capped at a stated maximum. Reasonable-cause relief can be requested but is evaluated case by case and is not automatic — that determination is made with the IRS, typically with the taxpayer's CPA or counsel involved.
What happens if a payroll tax deposit is late?
A separate failure-to-deposit penalty applies on a rising scale tied to how many days late the deposit is, with the highest tier reserved for amounts still unpaid well after an IRS notice. The rate is assessed on the late or short amount, not the full quarterly liability, and interest accrues in addition to the penalty.
Can Form 941 be corrected after filing?
Errors discovered after filing are corrected on Form 941-X, a standalone adjustment form rather than a refiled 941. Whether an error is treated as an "adjustment" or a "claim" affects the correction process; the employer's payroll or tax provider determines the correct treatment for a given error.
Does a business with no employees for the quarter still file Form 941?
Generally yes, unless the business has notified the IRS it will not be filing going forward (for example, by checking the final-return box on a prior filing) or has an approved seasonal-employer status. A quarter with zero wages paid is usually still a required "zero" filing rather than an automatic exemption.
Is the 10-day extension the same as a filing extension request?
No. There is no general extension-of-time-to-file form for Form 941 comparable to Form 7004 for many business income tax returns. The 10-day allowance is a built-in feature of the deposit rules, not a discretionary extension the employer applies for.
Where do the exact current-year due dates come from?
The IRS publishes the governing rule in the Form 941 instructions and Tax Topic 758, and a general tax calendar with the specific rolled-forward dates for the current year. Because a due date's exact calendar position shifts year to year around weekends and federal holidays, the current-year IRS calendar is the source to check rather than a prior year's dates.
