Tell HMRC about a change to your personal details

Relationship or family changes

Tell HM Revenue and Customs (HMRC) if:

  • you get married or form a civil partnership
  • you divorce, separate or stop living with your husband, wife or partner

You can tell HMRC online if you’re paid a salary or pension through PAYE. If you submit a Self Assessment tax return as well, your details will be updated for both.

You’ll need to sign in to use this service - if you do not already have sign in details you’ll be able to create them.

You’ll also need a National Insurance number (a temporary reference number will not work).

Tell HMRC straight away – if you do not, you could pay too much tax, or get a tax bill at the end of the year.

If you get Child Benefit

Tell HMRC separately about changes to your relationship or family if you get Child Benefit.

If your spouse or civil partner dies
