You don't "file" a Form W-2, you file a single tax return, which should include income and withholding reported on all W-2s.  You cannot file another tax return.  Since the information on your W-2 has been reported to the IRS, there is a very good chance the IRS will send you a letter proposing changes to your tax return to include the in come and withholding on the W-2 you didn't include.  If they don't, you will need to file an amended return. You need to wait until the return you filed has been processed by the IRS, and any refund you were expecting received before amending.  Note, the IRS will not start processing e-filed returns until February 12.  For more information on Amending your return, go to:
