Understanding W-2Cs
After you print the W-2 forms, you might need to make corrections to reported amounts. To make these corrections, you must issue a correction form (W-2C) that replaces or supplements the original W-2. Corrections can include:
Incorrectly reported amounts
Change in Social Security number
Change in employee name or address
You can rerun the W-2C workfile if you encounter errors on the W-2C forms. You can reprint W-2Cs for an entire version or for a selected group of employees, based on the data selections for the version.
When making corrections, you must send form W-3C to the Social Security Administration (SSA). The W-3C is the IRS-approved form for printing the corrected summarized amounts that are reported on the individual W-2Cs.
You can submit W-2C corrections to the federal government using the EFW2C electronic filing format.
Before you generate the Federal W-2C EFW2C workfile, you must first create W-2C records.
