How do I change the pay check deposit date?

It's great having you in the QuickBooks Community, @lizette1. 

You can set up a new pay schedule in QuickBooks Online (QBO) and choose it as the default to update your employees' paycheck deposit dates for the new pay periods. I can guide you through the steps. 

If you pay your employees via auto-payroll, I recommend turning it off first to add a new pay schedule. Kindly refer to the Turn off auto payroll section of this article for the steps: Set up and manage your Auto Payroll in QuickBooks Online Payroll. 

After this, add a new pay schedule with a different name to avoid confusion. Here are the steps: 

1. Go to Payroll, then Employees.
2. Select your employee.
3. From Employment details, select Edit.
4. From the Pay Schedule drop-down list, select + Add pay schedule.
5. Enter a distinguishable Pay schedule name.
6. Fill out the appropriate fields. Then select Save.
7. When done, click on Save.
8. Repeat the steps to for the rest of your employees if necessary.

If you're using direct deposit payroll, check out this article on when to send your payroll to pay your employees on time. 

For future reference, I'm adding this guide for running payroll reports to get helpful insights about your business and employees: Run payroll reports.
