IRS Form 941 - Employer's Quarterly Federal Tax Return

IRS Form 941 – In the world of payroll and tax compliance, few forms are as essential for U.S. employers as IRS Form 941. This quarterly federal tax return helps businesses report and reconcile employment taxes, ensuring the government receives accurate information on withheld income taxes, Social Security, and Medicare contributions. Whether you’re a small business owner, HR professional, or accountant, staying on top of Form 941 requirements is crucial to avoid penalties and maintain smooth operations. In this comprehensive guide, we’ll break down everything you need to know about IRS Form 941 for 2026, including due dates, filing instructions, recent updates, and more. We’ll draw from official IRS resources to provide reliable, up-to-date information.

What Is IRS Form 941?

IRS Form 941, officially known as the Employer’s Quarterly Federal Tax Return, is a key document used by employers to report federal income taxes withheld from employees’ wages, as well as the employer’s and employees’ portions of Social Security and Medicare taxes. It serves as a quarterly summary of payroll taxes, helping the IRS track compliance with employment tax laws. The form does not cover state taxes or unemployment taxes (those are handled by other forms like Form 940 for federal unemployment tax).

Essentially, Form 941 reports:

Total wages, tips, and other compensation paid.
Federal income tax withheld.
Taxable Social Security and Medicare wages.
Adjustments for items like sick pay, tips, and fractions of cents.
Total tax liability and deposits made.

This form ensures that employers are accurately withholding and depositing taxes throughout the year, which later reconciles with annual Forms W-2 and W-3. It’s revised periodically, with the March 2025 revision applicable for all quarters in 2025 and expected to extend into 2026 with potential updates.

Who Needs to File IRS Form 941?

Not every business is required to file Form 941, but most employers with employees must do so if they withhold federal income taxes or pay wages subject to Social Security and Medicare taxes. This includes corporations, partnerships, sole proprietorships, and nonprofits. Even if no taxes are due for a quarter (e.g., due to low wages), you may still need to file unless you qualify for an exception.

Key groups that must file:

Employers who pay wages to non-farm, non-household employees.
Businesses with employees subject to federal withholding.
Semiweekly or monthly depositors of employment taxes.

Exceptions include:

Seasonal employers, who only file for quarters with wages and check Line 18 on the form.
Household employers (use Schedule H with Form 1040 instead).
Agricultural employers (file Form 943 annually).
Tax-exempt organizations may have special rules but often still file if they have taxable wages.

If your business has closed or stopped paying wages, you must file a final return by checking Line 17 and providing the final wage payment date. Always use your Employer Identification Number (EIN) when filing—apply for one at IRS.gov/EIN if needed.

IRS Form 941 Due Dates for 2026

Filing Form 941 on time is critical to avoid penalties. The standard due date is the last day of the month following the end of the quarter. However, if you make timely, full deposits of all taxes due, you get an extension to the 10th day of the second month after the quarter ends. If a due date falls on a weekend or holiday, it shifts to the next business day.

For 2026, the due dates are:

First Quarter (January 1 – March 31): April 30, 2026 (or May 11, 2026, with timely deposits).
Second Quarter (April 1 – June 30): July 31, 2026 (or August 10, 2026, with timely deposits).
Third Quarter (July 1 – September 30): October 31, 2026 (falls on a Saturday, so November 2, 2026; or November 10, 2026, with timely deposits).
Fourth Quarter (October 1 – December 31): January 31, 2027 (falls on a Sunday, so February 1, 2027; or February 10, 2027, with timely deposits).

These dates align with general IRS guidelines, but always check for any adjustments due to holidays or extensions. For businesses in U.S. territories like Puerto Rico, additional rules may apply.

How to Fill Out IRS Form 941: Step-by-Step Instructions?

Filling out Form 941 requires careful attention to detail. The form is divided into five parts, and you’ll need payroll records, including wages paid, taxes withheld, and deposits made. Use the separate Instructions for Form 941 (available on IRS.gov) for line-by-line guidance.

Header and Basic Information

Enter your EIN, business name, address, and trade name (if applicable).
Check the box for the quarter you’re reporting (e.g., Quarter 1 for January-March).

Part 1: Report Your Tax Liability

This is the core of the form, where you calculate taxes:

Line 1: Number of employees who received wages for the specified pay period (e.g., March 12 for Q1).
Line 2: Total wages, tips, and compensation.
Line 3: Federal income tax withheld.
Lines 5a-5d: Taxable Social Security wages (x 0.124), tips (x 0.124), Medicare wages (x 0.029), and Additional Medicare Tax (x 0.009 for wages over $200,000).
Line 5e: Total Social Security and Medicare taxes.
Line 6: Total taxes before adjustments.
Lines 7-9: Adjustments for fractions of cents, sick pay, and tips/insurance.
Line 10: Total after adjustments.
Line 11: Qualified small business payroll tax credit (attach Form 8974 if claiming).
Line 12: Total taxes after credits.
Lines 13-15: Deposits, balance due, or overpayment (request refund or apply to next quarter).

If no wages are subject to Social Security or Medicare, check Line 4 and skip to Line 6.

Part 2: Deposit Schedule

Indicate if you’re a monthly or semiweekly depositor based on your lookback period (prior four quarters’ tax liability).
For monthly: Enter liability by month.
For semiweekly: Attach Schedule B (Form 941).

Part 3: Business Details

Check if your business closed (Line 17) or if you’re a seasonal employer (Line 18).

Part 4: Third-Party Designee

Optional: Authorize someone to discuss the return with the IRS.

Part 5: Signature

Sign under penalties of perjury, including date, title, and contact info. Paid preparers must also sign.

Use Pub. 15 for withholding tables and rates (e.g., Social Security wage base is $176,100 for 2025, subject to updates). For complex scenarios like aggregate filers or CPEOs, attach Schedule R.

Recent Changes to IRS Form 941 in 2026

The IRS regularly updates Form 941 to reflect tax law changes. For 2026, key updates stem from the One Big Beautiful Bill Act (OBBBA), which introduces deductions for qualified tips (up to $25,000) and overtime compensation (up to $12,500, or $25,000 for married filing jointly). These affect withholding but not Social Security/Medicare taxes—employers must adjust using updated Form W-4 and Pub. 15-T.

Other changes:

New “Aggregate Return Filers Only” section for agents, CPEOs, or third parties.
Expanded bank info on Line 15 for direct deposit refunds.
No more COVID-19 credits (expired after 2021).
Increased dependent care assistance limits to $7,500 starting 2026.

The March 2026 revision is expected to apply to all quarters, with drafts emphasizing these withholding rules. Employers should review IRS drafts for Form 941-X corrections, which now clarify OBBBA impacts.

How to File IRS Form 941?

Electronic filing (e-file) is recommended and required for many employers—it’s faster and reduces errors. Use IRS-approved software or the EFTPS system for deposits. Paper filing is allowed if your tax liability is low, mailed to addresses based on your state (e.g., Ogden, UT for western states). Include Form 941-V if making a payment.

For corrections, use Form 941-X. Reconcile quarterly filings with annual W-2 totals.

Penalties for Late Filing or Non-Compliance

Failing to file on time can result in penalties, including failure-to-file (up to 5% per month) and failure-to-deposit charges. Interest accrues on unpaid balances. To avoid this, make deposits via EFT and file promptly. The IRS offers relief for reasonable cause, but prevention is key.
