Child Benefit Claw Back
If you or your spouse/partner claim child benefit, and at least one of you has adjusted net income of £50,000 or more for the year, the highest earner must declare the benefit on their tax return in order to pay back part or all of the child benefit as a tax charge.
HMRC is writing to taxpayers who it thinks should have paid the child benefit tax charge for 2013/14, but didn't. Unfortunately some people who have received such letters are childless, or haven't claimed child benefit for decades.
If you have received one of those letters by mistake, don't ignore it. HMRC can alter your tax return to collect the tax it thinks is due. You need to reject any such incorrect alteration to your tax assessment within 30 days, but we can help you do this.
