on line 10 state that the EIN is invalid reject code FW2-505
when you paper file be sure to use a method where you're notified of delivery. be sure to attach all W-2s and any other forms required.
Problem: The IRS has rejected your Federal Tax Return because your EIN or Employer Identification Number on one of your W-2s is issued after the tax year.
Solution: Contact your employer and ask for the correct EIN for the current tax year you are filing.
the employer should issue a w-2c if you can contact them
if you are due a refund, it could take the IRS more than 6 months to issue it since they will first have to get to your return and then try to contact the employer.
you should make every effort to get hold of the employer and get a corrected w-2 (w-2c)
