IRS Tax:
Double Check the employer Identification Number (eIN)
When submitting Employer Reports (W-2s/W-3s), verify that you are submitting under the Employer's EIN.
When Employer Reports process under the Submitter's EIN, a Report Correction will have to be prepared to place wages under the correct EIN. In some cases, companies are receiving penalty letters from IRS as if the wages were never sent, which causes problems. Please be careful and double check that the right EIN is in the correct space.
See instructions in the Specifications for Filing Forms W-2 and Forms W-2c Electronically (EFW2 and EFW2C).
