If HMRC send you a P9 or P6 notification to change an employee's tax code, you need to apply it in your software.

 NOTE: If a tax code notice has an X after the code, this typically means you need to set the week 1 / month 1 flag. If you're not certain what tax code to enter, contact HMRC for advice. 

There are different steps depending on how HMRC contacted you. Follow the relevant steps below.

HMRC sent a letter

1. Select Payroll in the bottom left.
2. Double-click the required employee on your employee list.
3. Click the Employment tab.
4. In the Tax Code field, enter the tax code HMRC provided.
5. Click Save.

If HMRC specified a date that the tax code is effective from, you can enter this in your software. Select the + button and enter this date.
