Form 941 Quarterly Payroll Tax Return

Form 941, the Employer's Quarterly Federal Tax Return, is how most employers tell the IRS what they withheld and owe for payroll each quarter. It reports wages, tips, federal income tax withheld, and the employee and employer shares of Social Security and Medicare tax. It also reconciles the deposits you made during the quarter against the tax you actually owe.

Who files Form 941

Any employer who withholds federal income tax or Social Security and Medicare tax from employee pay files a 941 for every quarter, including quarters with no wages, until the business files a final return. Seasonal employers have a way to tell the IRS not to expect a return in quarters when they pay no wages. Household employers, agricultural employers and employers on the annual Form 944 follow different rules. See household employer rules for the first group.

Due dates through 2027

We work out the shifted dates with the IRS next-business-day rule. For the full year, including deposit dates, see our payroll deadlines calendar.

What the form shows

Form 941 starts with the number of employees and total wages, tips and other pay, then the federal income tax withheld. The middle lines break out Social Security and Medicare:

• Social Security wages and tips are taxed at a combined 12.4% (6.2% employee and 6.2% employer) up to the annual wage base, which is $184,500 for 2026. Once an employee reaches that limit, stop reporting that employee's wages on the Social Security line.
• Medicare wages and tips are taxed at a combined 2.9% (1.45% each), with no wage limit.
• Additional Medicare Tax is reported separately at 0.9% on wages over $200,000 and has no employer match.

Total tax after adjustments appears on line 12. That amount feeds your deposit-schedule test in future years. If you are a semiweekly depositor, Schedule B must show your liability by day, and the daily totals must match line 12.

Tips and overtime still appear in the wages you report here. The 2025 tax law created income tax deductions for qualified tips and qualified overtime, but those pay amounts remain subject to Social Security and Medicare tax and to income tax withholding. See tips and overtime reporting.

Changes to know for 2026

The 2026 instructions note that refunds on Form 941 are now issued by direct deposit, that any balance due must be paid electronically, that return transcripts are available through your IRS business tax account, and that aggregate filers must identify themselves in a new section.

The Form 944 option

Form 944 is an annual return for the smallest employers, generally those whose yearly liability for Social Security, Medicare and withheld income tax is $1,000 or less. You cannot just start filing it. You must receive written notice from the IRS first, and the IRS tells you to make the request during the first calendar quarter of the year. For 2026, the IRS allowed a phone request between January 1 and April 1, 2026, or a written request postmarked by March 16, 2026. To go back to quarterly filing you also need written IRS notice. Employers on Form 944 use a different lookback period for deposits, covered in our deposit guide.

Filing electronically

The IRS encourages e-filing Form 941, and a valid EIN is required to file or pay electronically. Certified professional employer organizations (CPEOs) generally must e-file. The separate rule that requires e-filing once you file 10 or more information returns applies to Forms W-2 and the 1099 series. See W-2 and W-3 filing.

Reconciling and correcting

Your Forms 941 for the year should tie to your Forms W-2 and W-3. The Social Security and Medicare tax on the 941s is roughly double the amount on the Form W-3, because the 941 includes both the employee and employer shares and the W-3 shows only the employee's.

To fix a mistake, you use Form 941-X, one form for each quarter you are correcting. If you underreported tax, the IRS says to file the 941-X by the due date of the return for the period in which you found the error and to pay what you owe when you file. Doing that generally keeps the correction free of interest and certain penalties. If you overreported, there are time limits on claiming a credit or refund, so do not wait.

Common mistakes

• Reporting deposits made, instead of tax owed, on the liability lines.
• Leaving off Schedule B as a semiweekly depositor.
• Not filing for quarters with no wages.
• Letting the 941 totals drift from payroll reports, W-2s and state returns.
• Paying a balance due with a card or paper check rather than electronically.
