Can previous payroll be added to quickbooks?

Hi there, emcllcja.

If you haven't run your first payroll in QuickBooks Online, then yes, you can add the payroll information through prior payrolls.

Here are the steps:

1. On the left panel, click Workers.
2. From the Employees tab, click the employee's name.
3. In the employee's profile, click the Enter 2018 prior pay details button. Note: Make sure to enter the employee's pay schedule and pay rate so you can see this option.
4. Follow the on-screen instructions and enter the payroll history.
5. Click Done.

Otherwise, contact one of our Payroll Support Specialists if you no longer have the option, or if it affects multiple paychecks.
