Do you know if you can correct already corrected W-2C Forms?

ANSWER

The BIDaWIZ Team's Answer:

Technically, you could file W-2c Form to correct a W-2c as detailed on page 22 of the 2014 W-2 and W-3 Form instructions.

However, the IRS statute of limitations of 3 years, 3 months as 15 days after the tax year has passed. Thus, if the intention is to reduce taxes, it has expired. They will accept it though if it's to increase taxes.
