Form 941 The quarterly payroll tax return

What Form 941 is

Form 941 is the Employer’s Quarterly Federal Tax Return. Each quarter it adds up three things for all your employees together:

• Wages, tips, and other pay
• Federal income tax you withheld from that pay
• Social Security and Medicare tax, both the worker’s share and yours

It is a report, not the payment. You pay most of these taxes during the quarter through deposits. Form 941 shows the IRS what you owed and what you already sent. How to run payroll is where these numbers start, one payday at a time.

Federal unemployment tax is not on Form 941. That is Form 940, a yearly return. State taxes are not on it either.

Who files Form 941

The IRS Instructions for Form 941 (March 2026 revision) say that if you pay wages subject to federal income tax withholding, or to Social Security and Medicare tax, you generally file Form 941 every quarter.

After you file your first one, you must file every quarter, even a quarter with no taxes to report. That rule ends only when you file a final return or one of these exceptions fits you:

• Form 944 filers. If the IRS sent you a notice to file Form 944, you file once a year instead.
• Seasonal employers. You do not file for a quarter with no wages. Check the seasonal box on line 18 each quarter you do file.
• Household employers. A family that pays a nanny or other household worker usually reports on Schedule H with the personal return.
• Farm employers. Wages for farm work go on Form 943.

Contractors are not on Form 941. You do not withhold from their pay. How to file a 1099-NEC covers the form they get.

Form 941 due dates

The return is due at the end of the month after each quarter.

There is a 10-day grace for people who paid on time. The instructions say that if you made all your deposits on time and in full, you may file by the 10th day of the second month after the quarter. For the first quarter, that is May 10.

What goes on the form, line by line

Most small employers fill in a short set of lines. The instructions describe each one.

• Line 1 is the number of employees who got pay for the pay period that includes the 12th day of the third month of the quarter. For the first quarter, that is the pay period that includes March 12.
• Line 2 is wages, tips, and other pay. Across the year it generally matches box 1 of your Forms W-2.
• Line 3 is federal income tax withheld.
• Lines 5a through 5d are the wages and tips subject to Social Security and Medicare, and the wages subject to the extra Medicare tax. Line 5e is the total tax on them.
• Line 6 is total taxes before adjustments.
• Line 7 adjusts for fractions of cents. Rounding each paycheck leaves small gaps, and this line fixes them.
• Lines 8 and 9 adjust for third-party sick pay, and for tips and group-term life insurance where you could not collect the worker’s tax.
• Line 12 is total taxes after adjustments and credits. This is the number the deposit rules key off.
• Line 16 is your tax by month, or Schedule B. The next section explains which.

The instructions set 2026 rates on lines 5a and 5c. Social Security is 6.2 percent each for the worker and for you, on wages up to $184,500 per worker. Medicare is 1.45 percent each, with no wage cap. That is why line 5 multiplies by 12.4 percent and 2.9 percent: both shares together. Employer payroll taxes percentage covers your share.

Deposits, and when you can pay with the return

The instructions give a small-employer rule. If line 12 is less than $2,500 for this quarter or for the prior quarter, and you did not hit the $100,000 next-day deposit rule, you do not have to make deposits. You may pay the full amount with a Form 941 filed on time.

If line 12 is $2,500 or more for both this quarter and the prior one, you deposit on your schedule. A semiweekly depositor also fills in Schedule B, which lists the tax by payday. A monthly depositor fills in the three months on line 16.

The instructions say every federal tax deposit must be made by electronic funds transfer. Can I do my own payroll? covers the monthly and semiweekly schedules and how the IRS assigns them.

How to file and pay

The IRS encourages filing Form 941 electronically. Payroll software and tax professionals file it through the IRS e-file system. A fee may apply. You can also mail it. The IRS address depends on your state and on whether you include a payment, and the instructions list both.

If you owe a balance with the return, the instructions name these ways to pay: electronic funds transfer, a credit or debit card, a check or money order, or an electronic withdrawal through e-file software. Card and withdrawal payments are for a balance due with the return, not for deposits. Card processors charge a fee.

A worked example

Say you have one employee. In the first quarter of 2026 you paid $12,000 in wages and withheld $900 in federal income tax. These figures are an example you can redo. They are not IRS amounts.

• Line 2, wages: $12,000
• Line 3, income tax withheld: $900
• Social Security: $12,000 times 12.4 percent is $1,488
• Medicare: $12,000 times 2.9 percent is $348
• Total for the quarter: $900 plus $1,488 plus $348 is $2,736

Half of the Social Security and Medicare, $918, came out of the worker’s checks. The other $918 is your share. The $2,736 total is $2,500 or more, so if the prior quarter was too, you deposit it on your schedule instead of paying with the return.

Fixing a filed Form 941

You do not file a second Form 941 to fix one. The instructions say to use Form 941-X, the adjusted return, filed on its own. It can be filed electronically.

Late returns and late payments cost money. The instructions say penalties and interest apply to late returns and late payments, at rates set by law, and point to sections 11 and 12 of Publication 15, the IRS Employer’s Tax Guide.

The state returns that run alongside

Form 941 covers federal taxes only. Most states have their own quarterly filing for unemployment tax, and states with an income tax have their own withholding return.

In Illinois, you file Form IL-941 each quarter for state withholding. Texas takes no state income tax, but you still file the quarterly unemployment report with the Texas Workforce Commission. In California and New York, the state pages cover the state returns and the accounts behind them. Pennsylvania adds local earned income tax on top.

The methodology page grades how much of that state work software takes off your desk. Gusto is one plain link. Patriot is the other service on this site.
