The charge applies if you or your partner have adjusted net income over £50,000 while receiving Child Benefit.

It's 1% of the Child Benefit received for every £100 of income over £50,000, up to 100% if income is £60,000 or more.

If both partners earn over £50,000, the higher earner is responsible for paying the charge.

You must register for Self Assessment with HMRC if you're liable for the charge.

The charge is calculated on the Child Benefit received in the tax year, not on future payments.

Payment is made through your Self Assessment tax return, typically due by January 31st after the tax year ends.

Failure to pay or report accurately can result in penalties, interest, and potential HMRC investigations.

You can opt out of receiving Child Benefit to avoid the charge, but this may affect state pension credits.

The income threshold of £50,000 hasn't changed since introduction, so inflation can increase liability over time.

Keep detailed records of Child Benefit payments and all income sources for accurate reporting and to support your tax return.
