Parents earning more than £60,000 a year are being urged to check whether they owe money to HM Revenue and Customs (HMRC) under the High Income Child Benefit Charge.HMRC issued the warning on X over the weekend, telling higher earners: “Earning over £60k? Check if you need to pay the High Income Child Benefit Charge.”The system operates on a sliding scale between £60,000 and £80,000.For every £200 earned above £60,000, one per cent of Child Benefit must be repaid.For example, someone earning £67,600 would be required to repay 38 per cent of their benefit.Once an individual’s income reaches £80,000, the full amount of Child Benefit must be repaid.’Earning over £60k?
