Tell HMRC about a change to your personal details

3. 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 also tell HMRC about your marriage, civil partnership, divorce or separation at the same time as changing your name.

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

If you get tax credits or Child Benefit

Tell HMRC separately about changes to your relationship or family if you get:

• tax credits
• Child Benefit

If your spouse or civil partner dies

Contact HMRC to report:

• the death of your husband, wife or civil partner
• changes to your income after their death
