Why has my tax code changed?

Tax codes are issued by HMRC directly. If there is a change in your working situation, or maybe you have multiple incomes, you might see a change in your tax code.

HMRC may update your tax code if:

  • you start to get income from an additional job or pension

  • your employer tells HMRC you have started or stopped getting benefits from your job

  • you get taxable state benefits

  • you claim Marriage Allowance

  • you claim expenses that you get tax relief on

  • You may also be put on an emergency tax code if you change jobs

If you think your tax code is incorrect, you are best to contact HMRC directly. 

If there is an update required for your code, they will issue this to us electronically. You can contact them using the following details:
