Form 941 and Payroll Tax Deposit Schedules Explained
Form 941 due dates for 2026, the monthly vs. semiweekly lookback test, the $2,500 exception, and the $100,000 next-day deposit rule, in one decision path.
This article is for general information, not tax or legal advice. IRS thresholds and due dates change, and weekend rollovers shift them year to year. Verify current figures with the IRS or a payroll professional before you file or deposit.
Filing Form 941 and depositing the tax are two separate obligations on two separate calendars. That distinction catches almost every new employer. You can file every quarterly return on time and still owe penalties, because the money was supposed to move weeks earlier.
Form 941 is a report. The deposit is the payment. The IRS wants the payment first, on a schedule that depends on how much tax you owed two years ago.
Below: what the form covers, when it’s due, how to tell whether you’re a monthly or semiweekly depositor, the two rules that override whatever schedule you land on, and what a late deposit costs.
What Form 941 reports, and what it leaves out
Form 941 is the quarterly federal employment tax return. Three things go on it:
- Federal income tax withheld from employee paychecks
- Employee Social Security and Medicare tax withheld
- The employer’s matching share of Social Security and Medicare
For 2026, Social Security runs at 6.2% on each side up to the $184,500 wage base. Medicare is 1.45% on each side with no cap. There’s also the 0.9% Additional Medicare Tax on wages above $200,000 for single filers, which you withhold from the employee but never match.
Line 12 is the number that matters most for scheduling. It’s your total tax liability for the quarter after adjustments, and it’s what the IRS uses later to decide which deposit calendar you belong on.
What Form 941 does not cover: federal unemployment tax and state unemployment tax. Those are separate returns with separate deadlines, and employers mix them up constantly.
| Form 941 | Form 940 (FUTA) | |
|---|---|---|
| Return frequency | Quarterly | Annual |
| Deposit trigger | Monthly or semiweekly schedule set by lookback | Cumulative liability over $500 in a quarter |
| Deposit due | 15th of next month, or Wed/Fri | Last day of the month after the quarter |
| $100,000 next-day rule | Yes | No |
State unemployment sits outside both. Your SUTA obligation has its own state agency, its own rate, and its own filing calendar. For the federal side of unemployment, see our FUTA guide.
One more form to know about: Form 944. If the IRS expects your annual employment tax liability to be $1,000 or less, it may put you on 944, an annual return instead of four quarterlies. You can’t switch on your own. You may ask the IRS to put you on 944 (by phone by April 1, or in writing postmarked by March 15), but you have to receive written notice back before you file one, and until you do, you file 941.
The four Form 941 due dates for 2026
The standard rule is the last day of the month following the close of the quarter. When that lands on a weekend or federal holiday, it rolls to the next business day, and 2026 has two of those.
| Quarter | Period covered | Standard date | Actual due date |
|---|---|---|---|
| Q1 2026 | Jan 1 to Mar 31 | April 30 | Thursday, April 30, 2026 |
| Q2 2026 | Apr 1 to Jun 30 | July 31 | Friday, July 31, 2026 |
| Q3 2026 | Jul 1 to Sep 30 | October 31 | Monday, November 2, 2026 |
| Q4 2026 | Oct 1 to Dec 31 | January 31 | Monday, February 1, 2027 |
October 31, 2026 is a Saturday. January 31, 2027 is a Sunday. Plenty of published 2026 calendars print the generic dates without catching the shift, so if you’re working from a chart, check the day of the week.
The 10-day extension you earn by depositing on time
There’s a bonus deadline most employers don’t use. If you made every deposit for the quarter on time and in full, you get until the 10th day of the second month after the quarter closes to file the return.
- Q1 2026: Monday, May 11, 2026 (May 10 is a Sunday)
- Q2 2026: Monday, August 10, 2026
- Q3 2026: Tuesday, November 10, 2026
- Q4 2026: Wednesday, February 10, 2027
It’s a reward, and a conditional one. One late or short deposit anywhere in the quarter kills the extension and puts you back on the standard date.
Monthly or semiweekly? Run the lookback
Your deposit schedule for a calendar year is set before the year begins, using a fixed 12-month window called the lookback period.
For 2026, the lookback period is July 1, 2024 through June 30, 2025. Take Form 941 line 12 from those four quarters and add them up.
- $50,000 or less → monthly depositor for all of 2026
- More than $50,000 → semiweekly depositor for all of 2026
A worked example
Say a small shop filed these four returns:
| Quarter in lookback | Form 941 line 12 |
|---|---|
| Q3 2024 (Jul to Sep 2024) | $11,480 |
| Q4 2024 (Oct to Dec 2024) | $12,940 |
| Q1 2025 (Jan to Mar 2025) | $12,310 |
| Q2 2025 (Apr to Jun 2025) | $13,020 |
| Lookback total | $49,750 |
$49,750 is under $50,000, so this employer deposits monthly through all of 2026. Note how close that is. One more hire or one bonus run in Q2 2025 would have pushed the total to $50,730 and made them semiweekly for the entire following year.
New employers get a simpler answer. If you had no employment tax liability during the lookback period, the total is treated as zero, which puts you on the monthly schedule for your first year.
The schedule is locked for the whole calendar year. Your business can double in size in March and you stay monthly, with one exception covered in the next section.
Monthly deposit dates
Everything you accumulate in a calendar month is due by the 15th of the following month. Wages paid in March are deposited by April 15. If the 15th falls on a weekend or holiday, it rolls to the next business day.
That’s the whole rule: one deposit covering one calendar month, by the 15th. It doesn’t mean “once a month whenever.”
Semiweekly deposit dates
Semiweekly has nothing to do with depositing twice a week. It’s a payday-based rule with two windows:
- Payday falls on Wednesday, Thursday, or Friday → deposit due the following Wednesday
- Payday falls on Saturday, Sunday, Monday, or Tuesday → deposit due the following Friday
So a Friday, March 6 payroll is deposited by Wednesday, March 11. A Tuesday, March 10 payroll is deposited by Friday, March 13.
Two mechanics get skipped in most short explainers. Semiweekly depositors always get at least three business days after the close of a semiweekly period. And if a legal holiday falls within those three weekdays, you get one extra business day for each holiday, which is why a Thanksgiving week payroll shifts.
The two rules that override your schedule
Monthly and semiweekly are the default. Two rules sit on top of them.
The $2,500 de minimis exception
If your total tax liability is under $2,500 for the current quarter or the preceding quarter, and you never triggered a next-day deposit obligation, you can skip deposits entirely and pay with your timely filed Form 941.
For a business with one part-time employee, that’s real relief. It’s also fragile. A strong quarter or a seasonal hire puts you over $2,500, with deposit obligations you weren’t watching for.
Check your running liability every quarter rather than assuming last year’s answer still holds.
The $100,000 next-day rule
If your accumulated employment tax liability reaches $100,000 on any single day, that entire amount is due by the next business day, whatever schedule you’re on.
A December bonus run is the realistic trigger. Pay out $300,000 in bonuses on top of a normal payroll and you’re looking at roughly $66,000 in federal withholding at the 22% supplemental rate plus about $45,900 in combined employee and employer FICA, assuming those employees are still under the $184,500 Social Security wage base. That’s about $111,900 accumulated in one day, and it’s due tomorrow.
The aftershock is the part that hurts. A monthly depositor who crosses $100,000 becomes a semiweekly depositor immediately, for the rest of that calendar year and all of the next one. One bonus run can change your deposit rhythm for up to two years.
If you’re planning a large bonus or commission payout, run the numbers before you release it, not after. Our post on why bonuses look so heavily taxed covers the supplemental withholding math behind that figure.
How to actually deposit, and what late costs
Federal tax deposits have to move electronically, through EFTPS, the Electronic Federal Tax Payment System.
Enrollment is the trap. EFTPS mails a PIN to your business address, and that can take a week or more. Start enrollment before your first payroll, not the week your first deposit is due. A missing PIN is not reasonable cause.
Once enrolled, schedule payments by 8 p.m. Eastern the day before the due date. A payment initiated at 9 a.m. on the due date is late.
Mailing a check to the IRS instead of depositing electronically doesn’t count as a deposit and can be penalized on its own. Do not treat the return envelope as a payment channel.
The failure-to-deposit penalty ladder
| How late | Penalty |
|---|---|
| 1 to 5 calendar days | 2% of the deposit |
| 6 to 15 calendar days | 5% |
| More than 15 days | 10% |
| Unpaid more than 10 days after the IRS’s first notice | 15% |
The tiers do not stack. Only the highest applicable rate applies to a given deposit, so a deposit 20 days late is penalized at 10%, not 2 plus 5 plus 10. Interest accrues separately from the original due date.
The percentages sound small until you attach dollars. An $8,000 deposit made seven days late costs $400 in penalty. Miss four of them in a year and you’ve spent real money on a calendar problem.
The IRS will consider penalty relief for reasonable cause, and first-time abatement is sometimes available if your compliance history is clean. Neither is something to plan around. Late deposits are one of the most common payroll mistakes small businesses make, and they’re also one of the most avoidable.
Getting the numbers right before the deadline
A deposit made on time for the wrong amount is still a problem. The figure you send is the sum of three things you already calculated when you ran payroll: employee federal income tax withheld, employee Social Security and Medicare, and your matching employer share.
So the deposit is only as accurate as the per-paycheck math behind it. If the withholding was wrong on a Tuesday in February, the deposit is wrong on March 15 and the return is wrong in April.
The Form 941 quarterly calculator rolls a quarter of payrolls into the line-by-line totals the form asks for, including line 12. For the per-paycheck side, WorkLogs44 computes each employee’s federal withholding and your employer FICA match at the same time, per person, with year-to-date wage base tracking so the Social Security cap truncates on the right paycheck.
If you’re still setting up, start with how to run payroll for one employee and how federal withholding is calculated. This article picks up where those leave off.
Put the four filing dates and your deposit dates on a calendar today, with reminders two business days early. That single step prevents most failure-to-deposit penalties.
Frequently Asked Questions
When is Form 941 due each quarter?
The last day of the month after the quarter ends. For 2026 that's April 30, July 31, November 2 (Oct 31 is a Saturday), and February 1, 2027 (Jan 31 is a Sunday). If every deposit for the quarter was made on time and in full, you get until the 10th of the second month instead.
Am I a monthly or semiweekly depositor?
Add up Form 941 line 12 for the four quarters from July 1, 2024 through June 30, 2025. $50,000 or less makes you monthly for 2026; more than that makes you semiweekly. New employers with no history in the lookback are monthly.
What is the lookback period for 2026?
July 1, 2024 through June 30, 2025, the 12 months ending June 30 of the prior year. It's fixed for the whole calendar year, so your schedule doesn't change mid-year unless you trigger the $100,000 rule.
Do I have to deposit if my payroll taxes are under $2,500 for the quarter?
No. If your total liability is under $2,500 for the current or the preceding quarter and you never accumulated $100,000 in a single day, you can pay with your timely filed Form 941 instead of depositing.
What is the $100,000 next-day deposit rule?
If your accumulated employment tax liability reaches $100,000 on any single day, that amount is due the next business day no matter which schedule you're on. A monthly depositor who triggers it becomes semiweekly immediately, for the rest of that year and all of the next.
What happens if I deposit payroll taxes late?
The failure-to-deposit penalty is 2% for 1 to 5 calendar days late, 5% for 6 to 15 days, 10% beyond 15 days, and 15% if it's still unpaid more than 10 days after the IRS's first notice. The tiers don't stack, and interest runs from the original due date.
Is Form 940 on the same deposit schedule as Form 941?
No. FUTA has no lookback and no monthly or semiweekly split. You deposit only once your cumulative FUTA liability passes $500 in a quarter, by the last day of the following month, and you file Form 940 once a year.
