Year-End Pay Stub: Why Your Last Paycheck Matters for Taxes
Key Takeaway
Your final pay stub is your W-2 verification tool
The YTD totals on your last pay stub of the year should closely match your W-2. Comparing them before you file catches errors that could cost you money or trigger an IRS notice.
Most people toss their pay stubs without a second thought. But your year-end pay stub is the single most valuable document for verifying your tax forms and catching payroll errors before they become tax problems.

Year-End Pay Stub vs. W-2: Field-by-Field Comparison
Here's how your final pay stub YTD totals map to your W-2 boxes:
| Pay Stub (YTD) | W-2 Box | Note |
|---|---|---|
| YTD Gross Earnings | Box 1 (Wages, tips, other compensation) | May differ slightly due to pre-tax deductions |
| YTD Federal Tax Withheld | Box 2 (Federal income tax withheld) | Should match exactly |
| YTD Social Security Wages | Box 3 (Social Security wages) | Capped at $176,100 for 2026 |
| YTD Social Security Tax | Box 4 (Social Security tax withheld) | Should be 6.2% of Box 3 |
| YTD Medicare Wages | Box 5 (Medicare wages and tips) | No wage cap—all earnings included |
| YTD Medicare Tax | Box 6 (Medicare tax withheld) | Should be 1.45% of Box 5 |
| YTD State Tax Withheld | Box 17 (State income tax) | Should match exactly |
| YTD 401(k) Contributions | Box 12 (Code D, E, etc.) | Pre-tax retirement deferrals |
Why W-2 Box 1 Is Lower Than Your YTD Gross Pay
This is the most common point of confusion. Your pay stub's YTD gross earnings includes everything, while W-2 Box 1 only shows taxable wages:
The $11,300 difference is your pre-tax benefit deductions. This is normal and expected.
Common Discrepancies and What to Do
YTD gross pay ≠ W-2 Box 1
Why: Box 1 excludes pre-tax deductions (401k, health insurance, HSA). Your pay stub YTD gross is your total earnings, while Box 1 is taxable wages.
Action: Subtract pre-tax deductions from YTD gross—it should equal Box 1.
Federal tax withheld doesn't match
Why: Payroll system error, mid-year W-4 change processed incorrectly, or supplemental wage withholding discrepancy.
Action: Contact payroll/HR immediately. This directly affects your tax return and could cause an unexpected bill or delayed refund.
Social Security wages exceed $176,100
Why: If you earned above the annual wage base, SS wages should cap at $176,100 for 2026.
Action: Verify your employer stopped withholding Social Security tax after you hit the cap.
State tax withheld is wrong
Why: Incorrect state withholding form, or you moved states mid-year.
Action: Contact payroll. You may need to file returns in multiple states.
401(k) contributions don't match
Why: Employer match is not reported the same as employee deferrals. Only your contributions appear in Box 12.
Action: Compare only your contributions (not the employer match) to Box 12.

Frequently Asked Questions
Why is my year-end pay stub important for taxes?
Your final pay stub of the year contains year-to-date (YTD) totals for earnings, taxes withheld, and deductions. These numbers should match your W-2 form. By comparing them, you can catch errors before filing your tax return—errors that could lead to an incorrect refund, unexpected tax bill, or even an IRS audit.
Should my last pay stub match my W-2?
Mostly, but not exactly. Your YTD federal tax withheld, state tax withheld, and Social Security/Medicare taxes should match the W-2 precisely. However, Box 1 (taxable wages) on your W-2 will typically be lower than your YTD gross pay because Box 1 excludes pre-tax deductions like 401(k) contributions and health insurance premiums.
When should I receive my year-end pay stub?
Your final pay stub comes with your last paycheck of the year, which depends on your pay schedule. If paid biweekly, your last 2026 pay stub would arrive in late December or early January (for a pay period ending in December). Your W-2 must arrive by January 31, 2027.
How long should I keep my year-end pay stub?
The IRS recommends keeping tax-related documents for at least 3 years from your filing date. However, many financial advisors suggest 7 years, as the IRS can audit up to 6 years back in cases of significant underreporting. Keep your year-end pay stubs with your tax records.
What if my W-2 is different from my year-end pay stub?
Small differences in taxable wages (Box 1 vs. YTD gross) are normal due to pre-tax deductions. However, if federal/state taxes withheld, Social Security, or Medicare amounts don't match, contact your employer's payroll department immediately. They must issue a corrected W-2 (W-2c) if there's an error.
Can I file taxes with my pay stub if I don't have my W-2?
You can use your year-end pay stub to file your return using IRS Form 4852 (Substitute for W-2) if your employer fails to provide a W-2 by the deadline. However, this may delay processing. Try to get your actual W-2 first by contacting your employer or using the IRS Get Transcript tool.
What is the Social Security wage cap for 2026?
The Social Security wage base for 2026 is $176,100. You only pay the 6.2% Social Security tax on earnings up to this amount. If you earn more, your year-end pay stub should show Social Security wages capped at $176,100, even if your total gross pay is higher.
