Add another Employer Identification Number (EIN) to your Company File
You have both an old and new EIN, but QuickBooks cannot process separate W-2s for each EIN within the same company file.
When a company changes EINs, the old EIN and new EIN are considered two separate entities. Because QuickBooks is designed to handle only one EIN per company file, it cannot separate the information for the old EIN from the new EIN.
To generate two sets of W-2 forms for employees, you must create a new company file for the new EIN. At the end of the year, you can print a set of W-2s for each company file, one set for the old EIN, and the other set for the new EIN.
