Other ways to report changes
You can also call or write to the Child Benefit Office.
The Child Benefit tax charge
Changes in circumstances may mean you may have to pay the Child Benefit tax charge. The charge affects you if your income (or your partner’s) is £50,000 or more.
You must still report changes even if you’ve stopped getting Child Benefit because of the Child Benefit tax charge.
