Form W-2C, Corrected Wage and Tax Statement is issued by an employer when a mistake is discovered on Form W-2. In TaxAct, you enter your wage information the same way, whether you receive Form W-2 or Form W-2C.
To enter the corrected W-2, see Form W-2 - Entering in Program
Note. If you receive Form W-2C after you have submitted your return to the IRS (and it has been accepted), then you will need to amend your return.
