Form 941: The Employer’s Quarterly Payroll Tax Return
Form 941, the Employer’s Quarterly Federal Tax Return, is the form most U.S. employers use to report the payroll taxes they withhold and owe each calendar quarter. It reconciles federal income tax withheld from wages plus the employee and employer shares of Social Security and Medicare (FICA) against what was deposited during the quarter. It is due four times a year: April 30, July 31, October 31, and January 31.
If you pay wages subject to employment taxes, you generally file Form 941 unless the IRS has specifically told you to file the annual Form 944 instead. The form does not, by itself, pay the tax. Most of the money moves through separate electronic deposits during the quarter, and Form 941 is the quarterly reconciliation.
What Form 941 reports
Form 941 reports three federal payroll taxes for the quarter: federal income tax withheld from employee wages, Social Security tax, and Medicare tax (together, FICA), plus any Additional Medicare Tax withheld. It sums wages paid, the tax withheld and matched, and the deposits already made, then shows a balance due or an overpayment.
The FICA piece has two components with different rules for 2026:
| Tax | Employee rate | Employer rate | 2026 wage base / threshold |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | First $184,500 of wages |
| Medicare | 1.45% | 1.45% | No wage cap |
| Additional Medicare Tax | 0.9% | none | Wages over $200,000 (per employee) |
Federal income tax withholding is not a flat rate. It is calculated per employee from Form W-4 elections and the IRS withholding tables. Additional Medicare Tax is withheld from an employee once that person’s wages pass $200,000 in the calendar year, and the employer does not match it. The employer share of Social Security and Medicare is a real cost on top of the amounts withheld from employees.
Quarterly deadlines and the 10-day extension
Form 941 is due by the last day of the month after each quarter ends. The four quarters are January to March, April to June, July to September, and October to December. If you deposited all taxes for the quarter on time and in full, you may get 10 extra calendar days to file the return.
When a due date lands on a Saturday, Sunday, or federal holiday, the deadline shifts to the next business day. The table below shows the standard dates and the extended dates for a 2026 filing cycle.
| Quarter | Period covered | Standard filing deadline | Deadline if all deposits were timely |
|---|---|---|---|
| Q1 2026 | Jan 1 to Mar 31 | April 30, 2026 | May 11, 2026 |
| Q2 2026 | Apr 1 to Jun 30 | July 31, 2026 | August 10, 2026 |
| Q3 2026 | Jul 1 to Sep 30 | November 2, 2026 (Oct 31 is a Saturday) | November 10, 2026 |
| Q4 2026 | Oct 1 to Dec 31 | February 1, 2027 (Jan 31 is a Sunday) | February 10, 2027 |
You generally must file every quarter once you have an employer identification number and are on the Form 941 schedule, even in a quarter with no wages, unless you are a seasonal employer, file final returns after closing, or employ only household or farm workers. Seasonal employers check a box on the form so the IRS does not expect a return in idle quarters.
Form 941 vs Form 944
Form 941 is quarterly; Form 944 is annual. The dividing line is expected annual employment tax liability: employers who owe more than $1,000 in total federal employment tax for the year file Form 941 four times, while very small employers whose annual liability is $1,000 or less may be assigned Form 944 to file just once. You cannot pick Form 944 on your own.
Only employers the IRS has notified in writing may file Form 944, and eligibility often traces back to what you indicated on Form SS-4 when you got your EIN. The threshold works out to roughly $4,000 or less in annual wages for a typical business, since FICA alone runs about 15.3% combined before income tax withholding.
| Feature | Form 941 | Form 944 |
|---|---|---|
| Filing frequency | Quarterly (4x/year) | Annually (1x/year) |
| Who files | Most employers | Small employers, by IRS notice only |
| Liability threshold | More than $1,000/year | $1,000 or less/year |
| Standard due date | Last day of month after quarter | January 31 of following year |
| Can you self-select | No (default) | No (IRS must assign) |
If you currently file Form 941 but expect annual liability of $1,000 or less, you can ask to switch. Send a written request postmarked by March 15, or call the IRS by April 1, and wait for confirmation before changing what you file.
Deposit schedules: monthly vs semiweekly
Form 941 reports tax, but the tax itself is usually deposited electronically during the quarter on one of two schedules: monthly or semiweekly. Your schedule for a calendar year is set by a lookback period, not by your current payroll size. Report $50,000 or less in the lookback period and you are a monthly depositor; report more and you are semiweekly.
The lookback period is the four quarters running July 1 of the second preceding year through June 30 of the prior year. For calendar year 2026, that window is July 1, 2024 through June 30, 2025. New employers with no lookback history start as monthly depositors.
The two schedules work differently:
- Monthly depositor. Deposit the employment taxes for a given month by the 15th day of the following month.
- Semiweekly depositor. For paydays on Wednesday, Thursday, or Friday, deposit by the following Wednesday. For paydays on Saturday, Sunday, Monday, or Tuesday, deposit by the following Friday.
Two rules can override your schedule. The $100,000 next-day deposit rule: if you accumulate $100,000 or more in employment tax liability on any single day, you must deposit it by the next business day, and a monthly depositor who triggers this becomes semiweekly for the rest of that year and the next. Semiweekly depositors also file Schedule B with Form 941 to report tax liability by day. Deposits generally must be made electronically through EFTPS.
Penalties for late filing and late deposits
Filing Form 941 late and depositing late are penalized separately. Late filing can run 5% of the unpaid tax per month or part of a month, up to 25%. Late deposits use a four-tier failure-to-deposit penalty that climbs the longer the deposit is overdue, so a missed deposit can cost far more than a missed form.
The failure-to-deposit penalty tiers under IRC Section 6656 are:
| Days late | Penalty on the deposit |
|---|---|
| 1 to 5 calendar days | 2% |
| 6 to 15 calendar days | 5% |
| More than 15 days | 10% |
| More than 10 days after first IRS notice | 15% |
Amounts still unpaid also accrue interest, and penalty relief may be available in some cases (for example, first-time abatement or reasonable cause), depending on your history and circumstances. Because payroll taxes include money withheld from employees, the IRS treats deposit failures seriously and can pursue responsible individuals through the trust fund recovery penalty.
Frequently asked questions
Who has to file Form 941?
Most U.S. employers that pay wages subject to federal income tax withholding or Social Security and Medicare taxes file Form 941 every quarter. Exceptions include employers the IRS has assigned to the annual Form 944, agricultural employers (Form 943), and household employers (Schedule H with Form 1040). Once you are on the Form 941 schedule, you generally file even in quarters with no wages.
When is Form 941 due?
Form 941 is due the last day of the month after each quarter: April 30, July 31, October 31, and January 31. If you deposited all taxes on time and in full for the quarter, you may have until the 10th day of the second month after the quarter to file. When a due date falls on a weekend or federal holiday, it moves to the next business day.
What is the difference between Form 941 and Form 944?
Form 941 is filed quarterly by most employers; Form 944 is filed once a year by very small employers whose annual employment tax liability is $1,000 or less. You cannot choose Form 944, the IRS must notify you in writing that you are eligible. Employers who owe more than $1,000 a year generally stay on the quarterly Form 941.
How do I know if I am a monthly or semiweekly depositor?
Your deposit schedule is set by a lookback period, the four quarters from July 1 two years back through June 30 of the prior year. If you reported $50,000 or less in that window, you are a monthly depositor and deposit by the 15th of the following month. If you reported more than $50,000, you are semiweekly and deposit within a few days of each payday.
What happens if I file Form 941 late?
A late Form 941 can draw a failure-to-file penalty of 5% of the unpaid tax for each month or part of a month it is late, capped at 25%. Late deposits are penalized separately, from 2% up to 15% depending on how late, plus interest. Penalty relief such as first-time abatement or reasonable cause may apply in some situations, depending on your compliance history.
Do I still file Form 941 if I paid no wages this quarter?
Usually yes. Once you are on the Form 941 schedule, the IRS expects a return each quarter even when you paid no wages, and you would file showing zeros. Exceptions include seasonal employers, who check a box so the IRS does not expect returns in off quarters, and businesses that have filed a final return after closing or ending payroll.
