Meet government requirements! All businesses must submit a W-3C Transmittal with their W-2Cs.
Paper Filing Due Date: As soon as possible after an error is discovered.
Use to Transmit: Form W-2C, Corrected Wage and Tax Statement
If you have identified errors in the W-2S filed by you, you need to take corrective measures and go through the entire process all over again. This is done by filing Corrected Wage and Tax Statements in W-3 tax forms and also a W-3c transmittal as well. Like the W-2 transmittal, this too is a compiled statement of corrected amounts paid as salary, wage and other compensation. The format is that the corrected amounts are mentioned side-by-side the previously reported figures.
