Quick Answer
Your last pay stub year-to-date totals should match your W-2 boxes within $1-2, but timing differences can create discrepancies. Box 1 (wages) may be lower due to pre-tax deductions like 401(k) contributions, while Box 3 (Social Security wages) caps at $176,100 for 2026. Compare each box systematically to identify legitimate differences versus errors.

W-2 employees who want to verify their tax documents are accurate before filing
How to match your pay stub with your W-2
Your final pay stub's year-to-date totals should closely match your W-2, but they won't be identical due to timing and calculation differences. The key is knowing which numbers to compare and why differences occur.
Step-by-step reconciliation process
Step 1: Compare gross wages
Step 2: Check federal tax withheld
Step 3: Verify Social Security wages
Example: $85,000 salary employee reconciliation
Common legitimate differences
Pre-tax deductions reduce W-2 Box 1:
Social Security wage cap:
If you earned over $176,100 in 2026, your pay stub might show $200,000 in gross wages, but W-2 Box 3 will cap at $176,100. This is correct.
Timing differences:

What you should do
1. Use our paystub explainer tool to upload both documents for automated comparison
2. Document any discrepancies with dollar amounts and which boxes are affected
3. Contact HR or payroll immediately if you find errors - W-2 corrections require Form W-2c
4. Don't file your taxes until discrepancies are resolved
5. Keep both documents together in your tax files
Key takeaway: Most differences between pay stubs and W-2s are legitimate due to pre-tax deductions and timing, but federal tax withheld should match within $1-2. Always verify before filing.
