Actually this is one of the most common questions Intuit’s Payroll support receives, and it is also such a common request by QuickBooks ProAdvisors that there is a special telephone prompt on the ProAdvisor Support Hot Line.
While QuickBooks cannot track more than 1 Employer Identification Number (EIN) for any single Company File, it is possible to use your desktop Payroll Subscription for more than one Company file and EIN. In fact you can have up to three Company files, each with their own unique EIN, on one Payroll Subscription. (Note: Enhanced Payroll for Accountants can support up to 50 Company file based EINs.)
- From the Menu bar, select Employees, and then Payroll and then Use My Existing Payroll Service.
- In the Account Maintenance window, choose Add File.
- Now select the Add to Subscription Number radio button. (Note: If you do not see the Add to Subscription Number radio button, a payroll service has already been validated in the company file.)
- If you do not see your own subscription in the list, select Other: I have an existing subscription and a Zip Code and enter your information.
- Click Next. When the Review Information window opens, click Next to add the company EIN.
- Click Print, or Return to QuickBooks. A Validating Payroll Subscription window opens and the service is added automatically.
- Verify the Service Key;. From the Menu bar, select Employees, then My Payroll Service, then Manage Service Keys. Click View to display the new Active Status Service Key.
You should be ready to go with payroll for this 2nd Company file. Best of luck.
