Welcome to the Community forum, Rochelle.
What you can do regarding payroll for that employee depends on how they were paid.
If the employee was paid by cheque, you can delete their pay cheque immediately in QuickBooks, which will allow the system to automatically recalculate your tax liabilities. Here’s how to do it:
1. Click on Payroll in the left navigation panel, then select Employees.
2. Click on the Paycheque list under the Run payroll button.

3. Filter by the employee and pay date, then locate the pay cheque. Click the dropdown arrow in the Action column and select Delete.

If the employee was paid via direct deposit and the cutoff has passed, or the deposit has already processed, you’ll need to contact our Live Payroll Support team to determine the best course of action.
Please note that reversals require employee authorization, are not guaranteed, and can take several business days. If a reversal isn’t possible, you'll have to recover the funds from the employee and then void or adjust the pay cheque in QuickBooks.
After you delete or void the pay cheque, please review the Payroll tax to confirm that your balances have been updated correctly. If a remittance has already been submitted for that period, you may need to make adjustments with CRA or Revenu Québec.
