For the 2025/26 tax year, Child Benefit is £26.05 a week for your eldest or only child, plus £17.25 a week for each additional child. The rates can change each tax year, so check the latest figures on GOV.UK. If you or your partner has adjusted net income above £60,000, the High Income Child Benefit Charge may reduce the amount you keep, and income above £80,000 can potentially repay it in full.
