Hi renetyler,
To add the payroll service key, you’ll want to add the client’s EIN to your subscription first.
Here’s how:
- Select Employees, then Payroll.
- Choose to Use My Existing Payroll Service.
- Under Identify Subscription, choose Use Subscription Number XXXXXXX (Payroll Subscription Version).
- Hit Next.
- Select Next to add the company EIN.
- Click Print or Return to QuickBooks Desktop. The Validating Payroll Subscription window opens, and the service is added automatically.
- Verify the Service Key.
You can refer to this article for additional information about adding EIN: Add an EIN to existing Payroll Subscription.
I also added helpful articles for your future reference in case you need some information about managing QuickBooks.
I’m always here if you need additional help.
