Important Things to Remember When Adding an EIN to QuickBooks
There are certain things you need to ensure before adding the EIN to QuickBooks. Let’s go through them individually.
- You are requested to use the same device and the same QBDT payroll account to process the payroll for multiple companies under Payroll Subscription.
- Don’t use more than one company file associated with the Employer Identification Number (EIN) for the same QuickBooks Payroll account. Using multiple files for the EIN can cause errors since it allows only one company file per EIN.
- Ensure that you maintain details such as contact information and the payroll administrator across all the companies around the payroll subscription.
- QuickBooks allows limited users of companies for payroll subscription. For example: a subscription to QuickBooks Enhanced Payroll allows adding up to only three companies.
- Ensure to keep your privacy with your service key. Sharing the key can allow unauthorized users access to payroll subscription information.
- Check if your QuickBooks Payroll subscription is active; if it is inactive, here’s how you can reactivate it:
- Go to the Employees tab, then move to the My Payroll Service section.

- Move to the Account/Billing Info.
- Now, sign in to your Intuit Account with the correct details.
- Under the Status section, choose the Re-subscribe option and follow the on-screen instructions.
- Enable the manual payroll under the Edit tab in QBDT to update the EIN.
- Use the same registered copy of QuickBooks Desktop on the same PC to process payroll for all users under one subscription.
- QBDT Payroll allows only one company data file per EIN.
- The contact details and payroll administrator must be the same for all companies under a single subscription.
- When you are using Direct Deposit, you can process payroll for multiple companies under the same subscription.
- Only a limited number of companies are allowed, as per the subscription, depending on the company data files:
- Payroll Basic: Standard, or Enhanced: up to 3 EINs
- Payroll Enhanced for Accountants: up to 50 EINs
- Payroll Assisted: Every EIN is billed separately, with applicable discounts for companies.
The above-mentioned points are to be followed and verified when you are changing or modifying the EIN in QuickBooks.
