W-2 Correction (W-2c): When You Need One and How to Get It

What Is a W-2c?

Form W-2c (Corrected Wage and Tax Statement) is the IRS form employers use to correct errors on a previously issued W-2. If your W-2 has an error — wrong Social Security number, incorrect wages, wrong employer EIN, wrong name — you need a W-2c before filing your taxes accurately.

Common Errors That Require a W-2c

• Wrong SSN: A single transposed digit means the IRS can't match your return to your earnings record — high priority to fix
• Incorrect Box 1 wages: Amount doesn't reconcile with your final pay stub YTD
• Wrong Box 2 withholding: Federal tax withheld doesn't match your records
• Employer EIN error: Wrong tax ID creates IRS matching problems
• Wrong name: Name doesn't match SSA records — can delay refund
• Missing state information: State wages or withholding omitted
• Incorrect Box 12 codes: Wrong retirement contribution amounts

How to Request a W-2c

1. Contact your employer's payroll department directly. Provide specific documentation — show them your final pay stub and point to the exact discrepancy. Payroll errors are often simple data entry mistakes that get corrected quickly.
2. Give the employer reasonable time. W-2c corrections involve filing with both the SSA and state agencies — it's not instant. Allow 2–4 weeks.
3. Get confirmation in writing that a W-2c is being issued and when to expect it.

What If Your Employer Won't Correct It?

If the employer is unresponsive, disputes the error, or has gone out of business:

1. Call the IRS at 800-829-1040 and explain the discrepancy
2. IRS will contact the employer on your behalf and give them 10 days to respond
3. If the employer still doesn't correct it, the IRS will advise you to file with Form 4852 (substitute W-2) reflecting the correct amounts

Filing Before the W-2c Arrives

The April 15 deadline doesn't wait for W-2c corrections. Options:

• File with the original W-2 if the error is minor and you're owed a refund — amend later with Form 1040-X when the W-2c arrives
• File an extension (Form 4868) to give time for the correction to arrive — but pay any estimated tax owed by April 15
• File with Form 4852 using your correct information if the employer won't issue a W-2c

After the W-2c: Do You Need to Amend?

If you already filed with the original (incorrect) W-2:

• If the correction changes your tax liability → file Form 1040-X (amended return)
• If the correction is to non-financial fields only (name, SSN) and doesn't change your tax → you may not need to amend, but should keep the W-2c with your records
