Migrated payroll on 28th february and now stuck with 28th of the month as pay date, how do I change to end of month?

Hi there, john.waits.

I'm glad to have you here and share some information about changing the pay date in QuickBooks Payroll.
 

Can you share what payroll are you using is it QuickBooks Online Standard payroll or Advanced? I want to make sure that you get the right information. I can see you're using one of them. I'll provide both answers for the standard and advanced.
 

For standard payroll, if we haven't submitted yet as well as deleted your first submitted payroll, we can change the pay date in the Account and Settings. 

1. Go to the Gear icon.
2. Select Account and Settings under Your Company.
3. Select Payroll.
4. Click the Pay schedule button.
5. Edit the pay date. Them, Save.

On the other hand, you can follow these steps for QuickBooks Online Advanced:

1. Go to Employees on the left side.
2. Click the New Pay run button at the upper-right corner.
3. Enter what date you want the pay run.
4. Hit the Create button. Afterward, it'll run that period for you.
