Update your employees' tax codes

Created on  | Last modified on 


This article explains how to update your employee's tax codes if you receive a P9 or P6 from HMRC in Sage 50cloud Payroll.


For the 2022/23 tax year, the personal allowance remains at £12,570. This means that the emergency tax code also remains at 1257L and you don't need to update employees tax codes.

However, if you receive a P9 or P6 from HMRC, you need to update an individual employee's tax code. You should also clear any week 1 / month 1 flags for the employee too.

Let's take a look at the steps!


TIP: There are no separate increases for Scottish and Welsh tax codes and the following steps apply.
