It's great to have you back in this forum, HelenRPW. Let me provide information to help you add an employee's prior pay and taxes to their regular payroll.
With QuickBooks Online, adding your employee's previous pay and tax will depend on how their profile and pay details are set up, particularly if they have been paid by another company. Thus, you'll need to enter the total pay and tax paid to date upon setting up their profiles. Refer to the screenshot for visual reference.
However, if you've already run your payroll, this option will be unavailable from your employee's details. As a workaround, you can add additional earnings if these regular pay types are taxable.
If these are non-taxable, you may include these Other earnings in your employees' pay as a Commission. To do this:
- Go to Payroll and select Employees.
- Choose the applicable employee and select Additional Pay from the Actions icon (at the top right of the page).
- Select or search for the pay type you want to add. If you can’t find the pay type you’re looking for, you can add it by selecting the plus sign icon.
- Click Actions and choose Other Earnings.
- Then, select Add next to Commission.
- Edit the Name for the earnings if needed.
- Enter a Default amount if you pay the same amount each pay period. You can edit this amount when you run payroll.
- Save your changes, then close the window.
