High Income Child Benefit Tax Charge

Overview

You may have to pay a tax charge, known as the ‘High Income Child Benefit Charge’, if you have an individual income over £50,000 and either:

you or your partner get Child Benefit
someone else gets Child Benefit for a child living with you and they contribute at least an equal amount towards the child’s upkeep

It does not matter if the child living with you is not your own child.

This guide is also available in Welsh (Cymraeg).

What counts as income

To work out if your income is over the threshold, you’ll need to work out your ‘adjusted net income’.

Your adjusted net income is your total taxable income before any personal allowances and less things like Gift Aid.

Use the Child Benefit tax calculator to get an estimate of your adjusted net income.

Who pays the tax charge

If your individual income is over £50,000 and so is your partner’s, then whoever has the higher income is responsible for paying the tax charge.

‘Partner’ means someone you’re not permanently separated from who you’re married to, in a civil partnership with or living with as if you were.

If your income is over the threshold

You can choose to either:

get Child Benefit payments, and pay any tax charge at the end of each tax year
not get Child Benefit payments, and not pay the tax charge

If you choose to not get Child Benefit

You can still fill in the Child Benefit claim form. You need to state on the form that you do not want to get payments.

You need to fill in the claim form if you want to:

get National Insurance credits, which count towards your State Pension
ensure your child gets their National Insurance number automatically before they’re 16 - otherwise they need to apply for one themselves

Already getting Child Benefit

You can choose to either:

stop getting Child Benefit - sometimes known as ‘opting out’
carry on getting Child Benefit and pay any tax charge at the end of each tax year
