Tips For Reconciling Payroll Forms W-2, W-3, And 941

8/15/2026

When there are discrepancies between Forms 941 filed with the IRS and Forms W-2 and W-3 filed with the SSA, the IRS must contact the employer to resolve the discrepancies. This costs time and money for the Government and for the employer.

To help reduce discrepancies:

• Report bonuses as wages and as social security and Medicare wages on Forms W-2 and 941
• Report both social security and Medicare wages and taxes separately on Forms W-2, W-3, and 941
• Report employee portion of social security taxes on Form W-2 in the Box for social security tax withheld (Box 4), not as social security wages
• Report employee portion of Medicare taxes on Form W-2 in the Box for Medicare tax withheld (Box 6), not as Medicare wages
• Make sure the social security wage amount for each employee does not exceed the annual social security wage base limit
• Do not report noncash wages that are not subject to social security or Medicare taxes as social security or Medicare wages
• If an EIN is used on any Form 941 for the year that is different from the EIN reported on Form W-3, enter the other EIN on Form W-3 in the Box for "Other EIN used this year"
• Be sure that the amounts on Form W-3 are the total of amounts from Forms W-2, and
• Reconcile Form W-3 with the four quarterly Forms 941 by comparing amounts reported for:
  • Federal income tax withholding
  • Social security wages, social security tips, and Medicare wages and tips. Form W-3 should include Form 941 adjustments only for the current year (that is, if the Form 941 adjustments include amounts for a prior year, do not report those prior year adjustments on the current-year Forms W-2 and W-3)
  • Social security and Medicare taxes. The amounts shown on the four quarterly Forms 941, including current-year adjustments should be approximately twice the amounts shown on Form W-3. This is because Form 941 includes both the employer and employee portions of social security and Medicare taxes

Do not report on Form 941 backup withholding or federal income tax withholding on nonpayroll payments such as pensions, annuities, and gambling winnings. Nonpayroll withholding must be reported on Form 945, Annual Return of Withheld Federal Income Tax. See the separate Instructions for Form 945 for details.

Federal income tax withholding required to be reported on Forms 1099 or W-2G must be reported on Form 945. Only taxes and withholding properly reported on Form W-2 should be reported on Form 941.

Amounts reported on Forms W-2, W-3, and 941 may not match for valid reasons. If they do not match, the employer should determine that the reasons are valid. Retain the reconciliation so that a record exists of why amounts did not match in case there are inquiries from the IRS or the SSA.

See the Instructions for Schedule D (Form 941) if there is a need to explain any discrepancies that were caused by an acquisition, statutory merger, or consolidation.

Completing The Form 941-X Use a separate Form 941-X for each Form 941 that is being corrected. For example, if an error is discovered on the Forms 941 for the third and fourth quarters, file one Form 941-X to correct the third quarter Form 941 and file a second Form 941-X to correct the fourth quarter Form 941.

Following the guidelines below when completing Form 941-X will assist the IRS in processing Form 941-X timely and accurately:

• Type or print all entries
• Use courier font, if possible, for all typed or computer-generated entries
• Do not enter dollar signs. Commas and decimal points may be used. Enter dollar amounts to the left of any preprinted decimal point and cents to the right
• Always show an amount for cents. Do not round entries to whole dollars
• Complete all three pages of the Form and sign the Form on page 3
• Staple multiple sheets in the upper-left corner

EIN, Name, and Address
Enter the company’s EIN, name, and address in the spaces provided. Also enter the company name and EIN on the top of pages 2 and 3, and on any attachments. If the company’s address has changed since Form 941 was filed, enter the corrected information and the IRS will update the company’s address of record.

Return That is Being Corrected
In the box at the top of page 1 of Form 941-X, check the type of return (Form 941 or Form 941-SS) that is being corrected. Check the appropriate box for the one quarter being corrected. Enter the calendar year of the Form 941 being corrected. Enter the quarter and calendar year on pages 2 and 3, and any attachments.

Enter the Date Errors are Discovered
The date the error was discovered must be entered. If several errors are being reported that were discovered at different times, enter the earliest date an error was discovered. On Line 20 report any subsequent dates and related errors.

An Entry Must be Made on Each Line
All of the information requested must be provided at the top of page 1 of Form 941-X. One box must be checked (but not both) in Part 1. Check the box on Line 3 and any applicable boxes on Lines 4 and 5. In Part 3, if any line does not apply, leave it blank. Complete Parts 4 and 5 as instructed.

How Negative Amounts Should be Reported
Form 941-X uses negative numbers to show reductions in tax (credits) and positive numbers to show additional tax (amounts owed). When reporting a negative amount in columns 3 and 4, use a minus sign instead of parentheses.

For example, enter -10.59 instead of (10.59). However, if you are completing the return on a computer and the software only allows parentheses to be used to report negative amounts, use parentheses.
