Tax codes
Overview
Your tax code is used by your employer or pension provider to work out how much Income Tax to take from your pay or pension. HM Revenue and Customs (HMRC) will tell them which code to use.
This guide is also available in Welsh (Cymraeg).
Find your tax code
You can find your tax code:
-
by checking your tax code for the current year online - you’ll need to sign in to or create an online account
-
on the HMRC app
-
on your payslip
-
on a ‘Tax Code Notice’ letter from HMRC if you get one
If you check your tax code online or in the HMRC app, you can also:
- find your tax code for previous tax years
- sign up for paperless notifications - this means HMRC will email you when your tax code changes
