Do I need to be proactive about telling the tax man (HMRC) I earn more than the child benefit threshold?
unregister for child benefit but apparently If I do that then my wife will stop getting the automatic national insurance stamp each year and will lose years of state pension You probably got this wrong according to Citizen's Advice. You can choose not to receive any Child Benefit, if you don't want to pay the extra tax. However, HMRC is encouraging you to still fill out a Child Benefit claim form even if you choose not to actually receive any Child Benefit payments from them. This is because filling your claim form for Child Benefit can help you build up national insurance credits which can help protect your future state pension. This is particularly important if you've stopped work to look after children full time. It can also help protect your entitlement to other benefits such as Guardian's Allowance, and ensure your child is automatically issued with a National Insurance number before their 16th birthday. Completing a Child Benefit claim form will make it easier for payments to start again if your circumstances change and your income falls below the £50,000 limit. As for Self Assessment If you decide to continue getting Child Benefit, you'll have to fill in a self-assessment tax return. This is when you'll have to declare you were getting Child Benefit and pay the extra tax, known as the High Income Child Benefit Charge. You'll have to register for self-assessment if you are not already registered. You can choose to pay the tax charge either: The following is important though:-   It is your responsibility to pay the extra tax, even if you don't hear from HMRC. SOURCE
