Worker has been over-taxed

This article explains what to do if you have a worker that's been over-taxed, and your own calculations confirm this.

Written by Terence Cassidy

When you're running manual payroll calculations, if the calculations show that the worker was over-taxed, you need to run the following checks:

📌 Note: If the worker in question is on a cumulative tax code be sure to use the pay adjustment tables from HMRC.

  • That the employee has the correct tax code.

  • Check the tax year-to-date values.

  • Check your current process date, which tax period you're in.


Once you've reviewed the above, if your payroll calculation still shows that the employee has been over-taxed, please contact us via the MyAccess portal and reference the title of this article. So that we can progress your case, please include the following:

  • Screenshots of the affected payslip alongside the last three payslips for this worker.

  • Screenshot of payroll details for this worker.

  • Your own calculations for this worker.

  • A screenshot of the HMRC calculator results.

  • If the worker is non-cumulative, please still provide the above.
