Form 941 Due Dates and Payroll Tax Deposit Schedules

10/2/2026

Ask a client when payroll taxes are due and most will name the quarterly Form 941 date. That is the date the return is due, and it is usually the least risky date on the payroll calendar. The penalties that actually hurt employers come from the deposit schedule: monthly or semiweekly, set by a lookback period the client has never heard of, and overridden by a next-day rule that applies the moment a large payroll hits.

This post separates the two calendars. First the 941 due dates for filing, which are simple. Then the deposit rules, which are where practitioners earn their fee: how the lookback period decides the schedule, how semiweekly deposits are timed, when the $100,000 next-day rule applies, the narrow exceptions that let small employers pay with the return, and the penalty tiers that reward fixing a missed deposit quickly. The figures below come from IRS Publication 15 (Circular E) and the Form 941 instructions; check both each year, since they are the controlling sources.

The Filing Calendar: Form 941 Is Due the Month After the Quarter

The Form 941 instructions put the rule in one sentence: the return is due by the last day of the month that follows the end of the quarter.

Quarter	Quarter ends	Form 941 due
January–March	March 31	April 30
April–June	June 30	July 31
July–September	September 30	October 31
October–December	December 31	January 31

Two refinements:

The 10-day grace for timely depositors. If the employer made timely deposits in full payment of the quarter's taxes, it may file by the 10th day of the second month after the quarter, for example May 10 for the first quarter. The extra days apply only if every deposit was on time and in full; they are a reward for clean deposits, not a general extension.

Weekends and holidays. When a due date falls on a Saturday, Sunday or legal holiday, the return is timely if filed the next business day. That is why the January date in particular moves around from year to year. Take each year's actual dates from the IRS calendar, not from last year's planner.

Once an employer files its first Form 941 (for the quarter in which it first paid wages subject to withholding or FICA), it must file every quarter, even with nothing to report, unless it is a seasonal employer or files a final return. Very small employers may be told by the IRS to file the annual Form 944 instead; that changes the filing calendar and, as discussed below, the lookback rules.

The Deposit Calendar: Where the Penalties Come From

Federal income tax withheld, both halves of social security and Medicare, and Additional Medicare Tax withheld are deposited, not paid with the return. (FUTA has its own quarterly deposit rule and is not covered by the schedules below.) Every deposit must be made by electronic funds transfer: EFTPS, IRS Direct Pay, the IRS business tax account, or a third party such as a payroll provider acting for the employer. A new employer that indicated a federal tax obligation when it got its EIN is pre-enrolled in EFTPS, but someone still has to activate it.

Publication 15 makes a point that clients routinely get wrong: the deposit schedule is not determined by how often the employer pays its workers. Weekly payroll does not make a monthly depositor semiweekly, and monthly payroll does not make a semiweekly depositor monthly. The schedule comes from the lookback period.

The lookback period

For a Form 941 filer, the deposit schedule for a calendar year is set by the total taxes reported on Form 941 (line 12) for the four quarters ending on June 30 of the prior year. Publication 15 describes the lookback period as running from July 1 to June 30: the year starting two Julys ago and ending last June.

$50,000 or less in the lookback period: monthly schedule depositor.
More than $50,000: semiweekly schedule depositor.

For employers that filed Form 944 (or Forms 943 or 945) in the current year or either of the two preceding years, the lookback period is the calendar year two years earlier instead. That is the trap when a small employer grows from Form 944 back to Form 941: the lookback is not the July-to-June window they would expect.

New employers are treated as having zero liability in any lookback quarter before they started, so they begin as monthly depositors. The $100,000 rule (below) can change that in the first year.

Publication 15 tells employers to determine their schedule before the beginning of each calendar year. In practice the IRS also sends a notice, but the notice is not the rule. A practitioner who checks the lookback total each fall catches the client crossing $50,000 before the first January payroll, not after the first penalty notice.

Monthly schedule

A monthly depositor deposits the taxes on payments made during a month by the 15th day of the following month. January payroll taxes are due February 15, and so on. Monthly depositors do not file Form 941 monthly; they deposit monthly and file quarterly.

Semiweekly schedule

A semiweekly depositor's deadline depends on the payday, per Publication 15:

Payday falls on	Deposit by the following
Wednesday, Thursday and/or Friday	Wednesday
Saturday, Sunday, Monday and/or Tuesday	Friday

Semiweekly depositors always get at least three business days after the end of a semiweekly period. If one of those days is a legal holiday, they get an extra day for each holiday. For deposit purposes, "legal holiday" means a District of Columbia legal holiday only; statewide holidays do not count, which surprises employers in states with their own holidays.

Two more semiweekly rules:

Periods spanning two quarters. If one semiweekly period contains paydays in two different quarters, the liabilities must be deposited separately even though they share a due date. Publication 15's example is a Wednesday, September 30 payday and a Friday, October 2 payday: two deposits, both due the following Wednesday.
Schedule B. Semiweekly depositors must file Schedule B (Form 941), the record of tax liability by payday, with every Form 941. A Schedule B that does not tie to the deposits, or that reports liabilities on the wrong dates, is a common reason the IRS's system proposes an "averaged" failure-to-deposit penalty even when the deposits were actually on time.

Business days only

If a deposit is due on a day that is not a business day, it is timely if made by the close of the next business day. A business day is any day other than Saturday, Sunday or a legal holiday.

The $100,000 Next-Day Deposit Rule

This is the rule that overrides both schedules, and the one most likely to catch a monthly depositor with a one-off event: a bonus payroll, a year-end distribution, or the exercise of stock compensation.

Publication 15: if an employer accumulates $100,000 or more in taxes on any day during a deposit period, it must deposit the tax by the next business day, regardless of whether it is a monthly or semiweekly depositor. The threshold is measured before any reduction for nonrefundable credits.

The mechanics matter:

Accumulation stops at the end of a deposit period. For a semiweekly depositor, liability does not keep adding up across the Saturday-to-Tuesday and Wednesday-to-Friday periods. Publication 15's example: $95,000 accumulated on a Tuesday and $10,000 on Wednesday do not trigger the rule, because they fall in different periods.
After a next-day deposit, accumulation starts over. Once $100,000 is reached, counting stops at the end of that day and starts fresh the next day.
A monthly depositor that hits $100,000 becomes a semiweekly depositor the next day and stays one for at least the rest of that calendar year and the following calendar year. Publication 15's example is a new business that pays $40,000 and then $60,000 of payroll tax liability in its first week. It must make a next-day deposit and is a semiweekly depositor from then on.

The practical control is simple: any client who could ever approach a $100,000 daily liability (one large bonus run is enough) needs a standing instruction that bonus payrolls are flagged to whoever schedules deposits before the payroll runs.

When Paying With the Return Is Allowed

Publication 15 allows a payment with a timely filed Form 941, instead of a deposit, in narrow cases:

The $2,500 rule. The total tax liability for either the current quarter or the prior quarter is less than $2,500, and the employer did not incur a $100,000 next-day obligation during the current quarter. If you are not sure the current quarter will stay under $2,500 (and the prior quarter was not under it), deposit on the regular schedule anyway.
Accuracy-of-deposits shortfalls for a monthly depositor, discussed next. That payment may be $2,500 or more.

Anything else paid with the return instead of deposited is penalized as a failure to deposit, even though the money reached the IRS on time with the return.

The Accuracy-of-Deposits Rule

Employers must deposit 100% of the liability by each due date, but Publication 15 waives the penalty for a shortfall if both conditions are met:

The shortfall does not exceed the greater of $100 or 2% of the amount required to be deposited; and
The shortfall is made up by the makeup date.

The makeup date for a monthly depositor is the due date of the return for the period, and the shortfall can be paid with the return. A semiweekly depositor must make it up by the earlier of the first Wednesday or Friday falling on or after the 15th of the month after the shortfall, or the return's due date.

The rule exists for rounding and small calculation errors. It does not cover a deposit that was simply skipped.

Failure-to-Deposit Penalties: The Clock Is in Calendar Days

The penalty tiers in Publication 15 are where a quick correction pays off:

Situation	Penalty
Deposit made 1 to 5 days late	2%
Deposit made 6 to 15 days late	5%
16 or more days late, but before 10 days from the first IRS notice	10%
Paid directly to the IRS or with the return instead of deposited (outside the exceptions)	10%
Still unpaid more than 10 days after the first notice, or the day notice and demand for immediate payment is received, whichever is earlier	15%

Late days are counted in calendar days from the due date. A missed deposit discovered on day four costs 2% if it is made that day and 5% if someone waits until after the weekend. The instruction to give staff: when a deposit is missed, deposit immediately, then work out what went wrong.

Deposits are generally applied to the most recent liability within the quarter, which can turn one late deposit into a series of apparently late ones. Publication 15 lets the employer designate how a deposit is applied within 90 days of a penalty notice; use that right before arguing about the penalty itself.

Relief and the bigger exposure

The penalties do not apply where the failure was due to reasonable cause and not willful neglect. Publication 15 also describes waivers for an inadvertent failure in the first quarter an employer was required to deposit, or the first time after its deposit frequency changed (subject to net-worth and size limits), and for a first deposit sent directly to the IRS instead of by EFT.

Above all of this sits the trust fund recovery penalty: 100% of unpaid withheld income tax and the employee share of FICA, assessable personally against any responsible person who willfully failed to collect, account for or pay it over. Publication 15 lists accountants among the people who can be treated as responsible. A practitioner who controls a client's payroll account or signs its deposits should understand exactly where that line is. Our post on payroll audits and DOL penalties covers the wage-and-hour side of the same exposure.

A Practitioner's Quarterly Checklist

For each payroll client, the controls that prevent nearly every deposit penalty:

Each fall: compute the lookback total and confirm the next year's schedule. Note any client within about 10% of $50,000.
At onboarding: confirm EFTPS or another EFT method is active and who has authority to initiate deposits.
Every payroll: record the liability on the payday (not the period-end date) and schedule the deposit from the payday.
Every bonus or unusual payroll: check the $100,000 rule before the payroll runs.
Month end: reconcile deposits to liabilities by payday, so a Schedule B or monthly summary ties before the quarter closes.
Quarter end: reconcile Form 941 to the payroll register and the deposit history; at year end, reconcile all four quarters to Forms W-2 and W-3.

The year-end tie-out is where errors from all four quarters come to light. Our year-end payroll reconciliation checklist and the page on reconciling Forms W-2, W-3 and 941 walk through it, and the payroll tax rate changes post covers the wage-base updates that change the liability itself each January. Multi-state employers add state deposit schedules on top of the federal ones; see multi-state payroll withholding.

Getting the Return Itself Right

Most Form 941 problems are not timing problems. They are reporting errors: liabilities on the wrong line, a Schedule B that does not match line 12, adjustments for sick pay, tips or group-term life reported incorrectly, and prior-quarter errors fixed on the current return instead of on Form 941-X. Each of these produces IRS notices that look like deposit failures.

For staff who prepare or review the return, the How to Properly Complete the 941 Form webinar focuses on exactly that form. Firms that also want to work on the penalty side can pair it with How to Minimize and Eliminate Payroll Penalties and Payroll Reconciliation and Reporting.

Keep the Two Calendars Separate

The filing calendar has four dates a year. The deposit calendar can have more than a hundred for a semiweekly employer, and a single bonus run can rewrite it. Practices that treat them as one calendar miss deposits; practices that track them separately, with the lookback checked each fall and the $100,000 rule built into payroll approval, rarely see a failure-to-deposit notice.

Frequently Asked Questions

What are the Form 941 due dates?

Form 941 is due by the last day of the month after each quarter ends: April 30, July 31, October 31 and January 31. If the employer made all of the quarter's deposits on time and in full, it can file by the 10th day of the second month after the quarter, such as May 10 for the first quarter. When a due date falls on a weekend or legal holiday, the return is due on the next business day, so check each year's IRS calendar for the actual dates.

How do I know if I am a monthly or semiweekly depositor?

Look at the lookback period. For a Form 941 filer, that is the four quarters from July 1 two years ago through June 30 of last year. If total taxes reported on line 12 of those four returns were $50,000 or less, you deposit monthly for the whole calendar year; if more than $50,000, you deposit semiweekly. How often you pay employees does not matter. New employers start as monthly depositors, and Form 944 filers use a different lookback year, as Publication 15 explains.

When are semiweekly payroll tax deposits due?

Taxes for paydays on Wednesday, Thursday or Friday are due the following Wednesday. Taxes for paydays on Saturday, Sunday, Monday or Tuesday are due the following Friday. Semiweekly depositors always get at least three business days after the semiweekly period closes, plus an extra day for each District of Columbia legal holiday among those days. Semiweekly depositors must also file Schedule B with Form 941 to report liabilities by payday.

What is the $100,000 next-day deposit rule?

If an employer accumulates $100,000 or more of employment taxes on any day in a deposit period, it must deposit by the next business day, whatever its normal schedule. The threshold is measured before nonrefundable credits, and accumulation does not carry across deposit periods. A monthly depositor that triggers the rule becomes a semiweekly depositor from the next day for at least the rest of that year and all of the following year, so a single large bonus payroll can change the client's schedule for two years.

Can a small employer pay payroll taxes with Form 941 instead of depositing?

Only in limited cases. Publication 15 permits payment with a timely filed return if the total liability for the current quarter or the prior quarter is less than $2,500 and no $100,000 next-day obligation arose in the quarter. A monthly depositor can also pay a small shortfall under the accuracy-of-deposits rule with the return. Outside those exceptions, money paid with the return instead of deposited draws a 10% failure-to-deposit penalty even though it arrived with the return on time.

What is the penalty for a late 941 deposit?

The failure-to-deposit penalty is 2% for deposits 1 to 5 days late, 5% for 6 to 15 days late, and 10% for 16 or more days late (or amounts paid directly to the IRS instead of deposited). It rises to 15% if the tax is still unpaid more than 10 days after the first IRS notice or after a demand for immediate payment. Days are counted in calendar days, so depositing as soon as a miss is discovered limits the cost. Reasonable-cause relief and certain first-time waivers are available.
