IRS Form 941, Employer’s Quarterly Federal Tax Return, is the form most U.S. employers use to report and pay federal employment taxes each quarter.
Employers use it to:
- Report federal income taxes withheld from employees’ wages
- Report both the employer and employee shares of Social Security and Medicare taxes (including Additional Medicare Tax)
- Report tips, adjustments, and certain credits
- Calculate the balance due or overpayment after accounting for tax deposits already made
Form 941 covers four quarters each year and is one of the most important ongoing tax obligations for businesses with employees. Filing and depositing correctly helps you avoid steep penalties for late filing, late payment, or failure to deposit.
Who Must File IRS Form 941?
You generally must file Form 941 quarterly if you:
- Paid wages subject to federal income tax withholding, or
- Paid wages subject to Social Security or Medicare taxes
This includes most businesses, nonprofits, government entities, and some tax-exempt organizations.
Exceptions and alternatives:
- Form 944 (Annual Return): Very small employers whose estimated annual employment tax liability is $1,000 or less may qualify to file annually instead of quarterly. You must request this (or be notified by the IRS). If your liability grows above the threshold, you still file Form 944 for that year but may need to switch later.
- Seasonal employers: File only for quarters with wage payments; check the seasonal employer box on each return you file.
- Household employers: Generally use Schedule H (Form 1040) instead.
- Agricultural employers: Use Form 943 for farmworkers.
- Final return: If you permanently stop paying wages, file a final Form 941 and check the final return box.
Even if you had no tax liability in a quarter, you usually must file unless you qualify as seasonal or have filed a final return.
IRS Form 941 Due Dates for 2026
Form 941 is due by the last day of the month following the end of the quarter. If you made all required deposits on time and in full, you get an extra 10 calendar days to file.
Here are the official 2026 due dates:
| Quarter | Period Covered | Quarter Ends | Normal Due Date | With Timely Deposits |
|---|---|---|---|---|
| 1 | January – March | March 31 | April 30, 2026 | May 10, 2026 |
| 2 | April – June | June 30 | July 31, 2026 | August 10, 2026 |
| 3 | July – September | September 30 | October 31, 2026 | November 10, 2026 |
| 4 | October – December | December 31 | January 31, 2027 | February 10, 2027 |
If the due date falls on a Saturday, Sunday, or legal holiday, file on the next business day. Use the March 2026 revision of Form 941 for all 2026 quarters.
Employment Tax Deposit Rules: Monthly vs. Semiweekly Schedule
You must deposit employment taxes electronically (usually via EFTPS) according to one of two schedules. Your schedule for 2026 depends on your lookback period taxes (July 1, 2024 – June 30, 2025 for most filers).
- Monthly schedule depositor: If you reported $50,000 or less in taxes during the lookback period. Deposit accumulated taxes for a month by the 15th of the following month.
- Semiweekly schedule depositor: If you reported more than $50,000 during the lookback period. Deposits are due on Wednesdays or Fridays depending on your payroll dates (see Schedule B instructions).
$100,000 One-Day Rule: If you accumulate $100,000 or more in tax liability on any single day, you generally become a semiweekly depositor for the next day and remain one for the rest of the year and the following year.
De minimis rule: If your total tax liability for the current quarter (and prior quarter) is less than $2,500 and you have no $100,000 next-day obligation, you can pay the taxes with your timely filed Form 941 instead of making deposits.
Semiweekly depositors must complete and attach Schedule B (Form 941) to report daily tax liabilities. Mismatches between Schedule B and your total tax can trigger averaged failure-to-deposit (FTD) penalties.
2026 Tax Rates Reported on Form 941
- Social Security (OASDI): 6.2% employee + 6.2% employer = 12.4% total on wages up to the 2026 wage base of $184,500.
- Medicare (HI): 1.45% employee + 1.45% employer = 2.9% total on all wages (no limit).
- Additional Medicare Tax: 0.9% withheld from employee wages exceeding $200,000 in a calendar year (employer matches only the regular 1.45%).
- Federal income tax withheld from wages, tips, and other compensation.
You also report tips, third-party sick pay adjustments, fractions-of-cents adjustments, and certain credits (such as the qualified small business payroll tax credit for increasing research activities via Form 8974).

Part 1 — Answer questions and report totals:
- Line 1: Number of employees paid wages/tips during the quarter (as of specific snapshot dates).

How and Where to File and Pay?
Strongly recommended: E-file Form 941 (and related forms like 941-X). Electronic filing is faster, more accurate, provides immediate confirmation, and is required for certain filers (e.g., CPEOs). You can e-file through IRS-authorized providers or software.
Deposits and payments:
- Use EFTPS (free) for required deposits and many balance-due payments.
- Credit/debit cards or direct pay options available for balance due (fees may apply).
- If paying by check, use Form 941-V payment voucher and mail to the correct IRS address.
Mailing addresses vary by state and whether you include a payment. Check the current instructions or IRS.gov for the exact address for your location (e.g., Kansas City or Ogden service centers for no-payment returns; Louisville for payments). Do not send to the Social Security Administration.
Penalties for Late Filing, Late Payment, or Failure to Deposit
Common penalties include:
- Failure to file on time
- Failure to pay on time
- Failure to deposit (FTD) — often the most expensive; can be “averaged” if your Schedule B does not match actual liabilities
- Trust fund recovery penalty (100% of unpaid trust-fund taxes) on responsible persons for willful failure to withhold/deposit/pay
Interest accrues on unpaid amounts. Reasonable cause may allow penalty abatement in some cases—respond promptly to IRS notices. E-filing and using EFTPS on time significantly reduces risk.
Amending a Return: Form 941-X
Use Form 941-X (Adjusted Employer’s Quarterly Federal Tax Return or Claim for Refund) to correct errors on a previously filed Form 941. File it separately (electronic options available). Corrections can affect your deposit history and may result in additional tax, refund, or penalty/interest adjustments. File before or with related returns to avoid processing issues.

Frequently Asked Questions (FAQs)
Can I file Form 941 electronically?
Yes — and it is strongly encouraged (and required for some filers). E-filing is available through IRS-approved providers.
What if I had no employees or wages this quarter?
You generally still need to file Form 941 (mark it appropriately) unless you are a seasonal employer who checked the box on prior returns or have filed a final return.
What is the difference between Form 941 and Form 944?
Form 941 is quarterly. Form 944 is annual and available only to very small employers with expected annual employment tax liability of $1,000 or less.
Do I need Schedule B?
Only if you are a semiweekly schedule depositor. Monthly depositors and de minimis filers generally do not.
How do I handle tips on Form 941?
Report tips on the appropriate lines (Social Security tips, Medicare wages/tips). Uncollected employee Social Security/Medicare tax on tips goes on line 9 as a negative adjustment.
When should I consult a tax professional?
For complex situations (third-party sick pay, aggregate returns, research credits, corrections, or large payrolls), work with a CPA or enrolled agent familiar with employment taxes.

Filing IRS Form 941 accurately and on time is essential for compliance and avoiding costly penalties. Use the official March 2026 revision, follow the current instructions, determine your correct deposit schedule using the lookback rules, and e-file + use EFTPS whenever possible.
