Report changes that affect your Child Benefit

Skip to contents of guide

If your circumstances change or you need to update your details

Report any changes that could affect your Child Benefit. If you do not, you may not get all the money you’re entitled to, or you may be overpaid and have to pay money back.

Only the person claiming Child Benefit can tell HM Revenue and Customs (HMRC) about a change of circumstances.

If you’ve already reported a change and you’re waiting to hear back, check when you should expect a reply.

Report the change to your family circumstances if:

If you do not report a change to your address and HMRC is not able to contact you, your payments will stop.

If you start to earn more than £60,000

If you or your partner earn more than £60,000 you may have to pay the High Income Child Benefit Charge.

You must still report changes even if you’ve stopped getting Child Benefit because of the Child Benefit tax charge.

If your bank or building society account changes

Tell HMRC if your bank or building society account details have changed by signing in to Government Gateway. You’ll need your Government Gateway user ID and password.

You’ll be able to register for Government Gateway if you have not used it before.

You can also tell HMRC using the HMRC app.

If you change your name or gender

Tell HMRC if you change your name or change your gender.

If you start to care for another child

If you have a baby or start to care for a child you can make a new claim for Child Benefit.

If you’re paid to look after a child by a local council or agency (for example fostering) tell HMRC.

If you move abroad or to Northern Ireland

Report the change to your family circumstances if:

  • you intend to go abroad for more than 8 weeks
  • you or your partner intend to move abroad for more than a year
  • you’re a Crown servant leaving the UK for a posting abroad
  • you move to or from Northern Ireland

If a parent dies

Tell HMRC if either of the child’s parents have died.
