Thanks for getting back to the thread, Ronnie.

Let me join in this conversation and provide you with further insights about your banking concerns for payroll.

With regard to your original query, you can only set up one bank account for direct deposit in QuickBooks Online Payroll. If you want to pay your employees using a separate bank, you'll have to update it in payroll settings . 

To answer your follow-up question, yes, you can't switch your direct deposit (DD bank) account not until you've completed your payroll processes. 

Let's make sure you don’t have any pending tax payments or payroll transactions. This is important to be sure your bank account change is successful and the payroll funds withdraw from the correct account.

Here's how to review your payroll transactions and tax payments status: 

Pending tax payments (QuickBooks Desktop Payroll Enhanced only)

1. Go to Employees menu and select Payroll Center. 
2. Click the Pay Liabilities tab.
3. Select the E-Payments tab to view any pending tax payments.

Pending payroll transactions

1. Select Employees and go to Payroll Center.
2. Click the Payroll tab to view any pending payroll transactions.

After that, you can now change your bank account and verify it with a test transaction. Once verified, the last step is to change it in your accounting preferences. This will ensure your payroll transactions and tax payments post to the correct account in your books.
