Fillable IRS Form W‑3C (Corrected Transmittal of Wage and Tax Statements)

Form W‑3C is the Corrected Transmittal of Wage and Tax Statements used by employers to correct errors on a previously filed Form W‑2 or Form W‑2C. The IRS requires a separate W‑3C for each batch of corrected W‑2/C forms you submit to the Social Security Administration (SSA). Our fillable PDF version lets you complete the form instantly, without installing any software.

What Is Form W‑3C and When Is It Required?

Employers must file Form W‑3C when any of the following items on a previously submitted W‑2 or W‑2C are changed:

• Employee’s name, Social Security number, or address
• Wage or tax amounts (e.g., federal income tax withheld)
• Employer identification number (EIN) or name

The form acts as a cover sheet for the corrected wage statements and must be sent to the SSA within 30 days of the correction.
