Form 941 and W-2 reconciliation comes down to one rule: the wages and withholding on your four quarterly Forms 941 have to agree with the totals on the Forms W-2 you file with the Social Security Administration (SSA). The IRS and the SSA compare them, and for tax year 2026 the Q4 Form 941 and the W-2s are due on the same day, February 1, 2027.
A mismatch you find in January is a mismatch you fix with no room to spare. This guide covers what the IRS compares, why the totals can legitimately differ, what changes on the 2026 W-2, and how to fix a mismatch before and after you file.
Do Form 941 and W-2 totals have to match?
The short answer
They have to reconcile. The IRS matches your four quarterly Forms 941 against the W-2 amounts totaled on Form W-3 for federal income tax withholding, Social Security wages, Social Security tips, and Medicare wages and tips.
Some differences are expected. Adjustments on Form 941 lines 7 through 9, and income tax withheld by a third-party sick pay payer, can explain a gap. If the amounts don't agree, the IRS or the SSA may contact you.
What each form reports and when it's due for 2026
Form 941 reports payroll taxes to the IRS each quarter. The W-2 reports each employee's annual wages and withholding to the SSA and to the employee, and Form W-3 transmits the W-2s. For how the 2026 Form 941 itself changed, see our guide to quarter-end Form 941 reporting.
| Form | Frequency | Filed with | What it reports | Due date |
|---|---|---|---|---|
| Form 941 | Quarterly | IRS | Wages, tips, and other compensation; federal income tax withheld; employer and employee Social Security and Medicare tax | Q4 2026: February 1, 2027 (January 31 is a Sunday) |
| Form W-2 | Annually | SSA (Copy A), plus a copy to each employee | Each employee's annual wages, tips, and taxes withheld | February 1, 2027, to file and to furnish |
| Form W-3 | Annually | SSA | Transmits Forms W-2 and totals their amounts | February 1, 2027 |
February 1, 2027
Due date for 2026 Forms W-2, Form W-3, and the Q4 Form 941, because January 31 falls on a Sunday.
An employer that made every deposit on time and in full may file the Q4 Form 941 by February 10, 2027 instead. There is no equivalent for W-2s: extensions to file are not automatic, and the IRS grants one 30-day extension on Form 8809 only for extraordinary circumstances or catastrophe. The Q3 2026 Form 941 is due November 2, 2026, since October 31 falls on a Saturday.
Failure-to-file and failure-to-furnish penalty amounts also increase for returns required to be filed after December 31, 2026, which includes these W-2s. Our guide to 2026 W-2 changes covers the penalty tiers and filing rules.

The IRS names four items in the Form 941 instructions. Add each line across all four quarters, including current-year adjustments, and compare the result with the W-2 amounts totaled on Form W-3, as described in the General Instructions for Forms W-2 and W-3.
| What the IRS compares | Form 941 | Form W-3 and W-2 |
|---|---|---|
| Federal income tax withheld | Line 3 | Box 2 |
| Social Security wages | Line 5a, column 1 | Box 3 |
| Social Security tips | Line 5b, column 1 | Box 7 |
| Medicare wages and tips | Line 5c, column 1 | Box 5 |
Line 2 reports amounts that are also included in W-2 box 1, but box 1 is not one of the four amounts the IRS lists for the match. Form 941 also reports both the employer and employee shares of Social Security and Medicare tax, while W-2 boxes 4 and 6 show tax withheld from employees, so those compare to the employee share only.
Why the totals can differ, and what causes real mismatches
These are the adjustments the Form 941 instructions describe, and each one can explain a gap between the 941 and the W-2s:
- Third-party sick pay. Line 3 excludes income tax withheld by a third-party sick pay payer, and the IRS says you reconcile that difference on Form W-3.
- Fractions of cents. Line 7 adjusts for rounding in the employee share of Social Security and Medicare tax.
- Sick pay liability transferred to you. Line 8 adjusts for the employee share that a third-party payer withheld and deposited.
- Uncollected tax on tips and group-term life insurance. Line 9 adjusts for employee tax you could not collect on tips, and on group-term life insurance premiums for former employees.
Mismatches that don't trace back to those adjustments usually come from one of three places:
- Corrections made on one side only. A Form 941-X correction with no matching Form W-2c, or the reverse.
- Different EINs. Forms W-2 and W-3 must carry the same payer name and EIN as the Form 941. If you used a different EIN on the 941, including a prior owner's, the Form W-3 instructions point you to box h, "Other EIN used this year." Employers with more than one EIN reconcile each one separately.
- Medicare wages below Social Security wages. The SSA rejects W-2 wage reports where Medicare wages and tips are less than the sum of Social Security wages and Social Security tips.
What's new on the 2026 W-2
None of the One Big Beautiful Bill Act (OBBBA) changes alter the four totals above. They change what you report on the W-2 itself, including new box 12 codes. Our walkthrough of the new box 12 codes for tips and overtime covers what to configure before year-end. The reference below covers the form changes.
OBBBA changes to W-2s and 1099s for tax year 2026
The One Big Beautiful Bill Act (P.L. 119-21) changed what employers and payers report on W-2s and 1099s, starting with tax year 2026. Workers claim the new deductions on their own tax returns. Employers and payers report the amounts.
- Tips. Workers can deduct up to $25,000 for tax years beginning after 2024 and ending before 2029. Qualified tips are voluntary cash or charged tips, including tips received through tip-sharing. Mandatory service charges don't count. Tips must be received in an occupation on the IRS list.
- Occupation codes. The IRS final regulations list more than 70 occupations in eight categories. Codes are on IRS.gov/TTOC. For a plain-language walkthrough, see our guide to the final qualifying occupation list.
- Overtime. Workers can deduct up to $12,500 ($25,000 if married filing jointly) of qualified overtime for the same tax years. Only the premium above the regular rate that the Fair Labor Standards Act (FLSA) requires qualifies.
- Payroll taxes don't change. Tips and overtime are generally still subject to federal income tax withholding, Social Security tax, and Medicare tax.
Changes to Form W-2
| Box | What changed |
|---|---|
| Box 12, code TP | Total cash tips reported to the employer. You must also list an occupation code in box 14b. |
| Box 12, code TT | Total qualified overtime compensation: the amount above the regular rate that the FLSA requires, such as the "half" in time-and-a-half. |
| Box 12, code TA | Employer contributions to the Trump account of an employee or an employee's dependent, paid under a section 128 Trump account contribution program. |
| Box 14a | "Other," the same use as the old box 14. |
| Box 14b | Treasury Tipped Occupation Code(s). Enter up to two codes. Required when box 12 code TP reports cash tips. |
- Trump account contributions. Beginning July 4, 2026, employers may contribute up to $2,500 a year, indexed for inflation after tax year 2027, to the Trump account of an employee or an employee's dependent. The amount is excluded from the employee's gross income if paid under a section 128 program. Learn more about Trump account contributions here.
- Territory W-2s. For Forms W-2AS, W-2CM, W-2GU, and W-2VI, check with the territory on whether codes TP, TT, and TA apply. The IRS W-2 instructions do not cover Puerto Rico.
How to fix a mismatch before and after you file
Run the comparison once Q4 payroll closes, before W-2s go to employees and the SSA:
- Total the four 941s. Add lines 3, 5a, 5b, and 5c across all four quarters, including current-year adjustments.
- Total the W-2s. Confirm Form W-3 equals the sum of your W-2s, then compare boxes 2, 3, 5, and 7 with the 941 totals.
- Trace each gap. Start with third-party sick pay and the adjustments on lines 7 through 9.
- Correct before you file. Fixing payroll records and forms before they're furnished and filed avoids a correction cycle.
- Correct after you file. Form 941-X corrects a filed Form 941. Forms W-2c and W-3c correct W-2s that were already filed.
A reconciliation that ties out in January is usually one someone started in October. Running the same comparison each quarter turns year-end into a confirmation instead of a cleanup.
Greenshades Tax & Compliance handles automated payroll taxes and year-end W-2 processing with automated checks and year-round compliance support, so the year-end comparison starts from numbers that already tie out.
