What this means
  • 50% of Child Benefit is charged backThe charge rises by 1% for each complete £200 of adjusted net income above £60,000, reaching 100% at £80,000.
  • Pension contributions can lower adjusted net incomeA £10,000 gross contribution would reduce the modelled adjusted income to the threshold, subject to pension limits and your actual tax position.
  • Claiming can preserve National Insurance creditsEven when payments are opted out, keeping the Child Benefit claim can protect State Pension credits and issue a National Insurance number to the child.

Adjusted net income has detailed rules, including benefits, savings, dividends and reliefs. Confirm the figure with HMRC guidance or an adviser. Not tax advice.

Method

How this calculation works

The 2026/27 weekly Child Benefit rates are multiplied by eligible weeks. The charge is 1% of benefit for every complete £200 of adjusted net income above £60,000, capped at 100% from £80,000. Gross pension and grossed-up Gift Aid entered are deducted for this estimate.
