How much of your child benefit the £60k–£80k charge claws back — and the exact pension contribution that makes it disappear. Computes the High Income Child Benefit Charge on the higher earner’s adjusted net income (ANI): 1% of the household’s child benefit per £200 of ANI above £60,000, reaching 100% at £80,000. Then it computes the lever most people miss — relief-at-source pension contributions are grossed up ×1.25 before they reduce ANI, so a precise net contribution can zero the charge while collecting higher-rate relief on top. General AI still quotes the old £50,000 threshold, cites the household-income reform that was announced and then dropped, and tells you Self Assessment is required when PAYE collection has been live since September 2025.
