The federal government does not use GREs for tax purposes. At implementation, however, you must at least enter a unique GRE number for the business group.

   To enter the unique identification number for the GRE:

1. In the Organization window, query the GRE if it does not already appear there. In the Organization Classifications region, select Government Reporting Entity, choose the Others button, and select Employer Identification.

2. Click a field of the Additional Organization Information window to open the Employer Identification window.

3. Enter a number for the GRE. You can use any sequence of numbers for this field.

   Note: If required, a Retirement Organization may have the same Employer Identification Number as an existing GRE.
