If discrepancies arise in tax figures or if corrections are needed after a payroll has been processed, users often need to submit an Additional Full Payment Submission (FPS). For example, if payslips were finalised with incorrect figures, reopen them, adjust the figures as necessary, and then submit an Additional FPS.

1. You can select to reopen the payslip by selecting the icon below.

2. Once this is done, you can make your change and then finalise as normal.

3. You can then create an addition FPS by selecting the RTI tab, selecting new, Selecting the additional FPS option and create.

This is pertinent when correcting mistakes like a wrong National Insurance number or year-to-date figures. An Additional FPS will update HMRC records without duplicating existing submissions. In cases of payroll transition from another software, using an Earlier Year Update (EYU) might be appropriate for rectifying previous tax submissions.
