Can I enter paychecks from May that were by check?

Welcome to the Community, @info-sunrisepreg.

I'll help you create a backdated paycheck in QuickBooks Online.

Yes, you can enter a backdated paycheck as long as it is not direct deposit and not after the tax period due date to pay the taxes or file forms for that period.

Here's how:

1. Go to Payroll, then Employees.
2. Select Run payroll.
3. If asked, select a payroll schedule.
4. Change the Pay date and Pay period.
5. Choose your employee and then add their salary or hours worked.
6. Pay method should be Paper check.
7. Preview and submit payroll.

If you get an error message to choose a more recent pay, you can reach our Customer Care team to help you further.
