Change your Federal Employer Identification Number (EIN)
Your Employer Identification Number (EIN) is a 9-digit number issued by the IRS. It identifies your business to the IRS and is used by QuickBooks Desktop Payroll services to validate your subscription. This article explains how to update your EIN when the organization or ownership of your business changes.
Make sure you consult your accountant or IRS on whether or not you need to submit separate W-2s for the new and the old EIN. If you do need to submit separate W-2s then you need to create a new company file for the new EIN.

To change your EIN in QuickBooks Desktop:
Go to Company > My Company. Click the edit icon at the upper right.

When prompted to save the new EIN, click Yes.
Choose Employees > My Payroll Service.
Select Change Payroll Service Options.
Click Add to My Subscription and follow the onscreen instructions for adding a new EIN to your payroll subscription.
