I understand that if you earn over £50k you need to repay the child benefit you get, the amount dependent on a sliding scale up to £60k (at £60k you pay it all back).
How is this done? If you only have one job do you still need to complete a tax return or can you just send a copy of your P60 (& details of any pension payments that can be deducted)?
And if you do need to complete a tax return does HMRC prompt you to do this?
Any insight would be appreciated
