I was instructed by the IRS to file an substitute W-2 but I don't have access to the employer EIN and the employer has ceased all communication.
If you don't know your Employer's EIN number, you can leave it blank and continue preparing your return as normal.
However, you will not be able to e-file your return without the EIN. You will need to print and mail it.
You can also contact the IRS at 1-800-829-1040. They can confirm the EIN for you. You'll need to give them the company name and address. There may be a 2-3 hold time before you speak to a representative.
Thanks a lot for your quick response! That's a great route to take!
