Hi,I underpaid an hourly, monthly paid employee and need to make an additional payment before the usual payrun. How do I do that in standard payroll please?

Hi heathersalt78-gm, thanks for joining the Community 🙂 - to do this, you can rollback the payroll to correct the previous pay (navigate to payroll > pay history > select relevant period > actions > delete payroll) - from here, return to the payroll homepage and click 'run payroll' to re-run; you can then add the correction as a separate earnings line on the payslip or edit their regular earnings amount. Once complete, go to taxes > payroll tax and resubmit the FPS as 'option H - correction to earlier submission' to over-write the existing submission to HMRC.
