Who do I contact for changes to my tax code?
Answer
In most cases, HMRC will automatically update your tax code when your income changes.
If HMRC has the wrong information about your income, you may be given an incorrect tax code.
To correct your tax code, make sure HMRC has up-to-date details about your income.
