High Income Child Benefit Charge: adjusted net income and pension planning
By GrowThenDraw Editorial Team · Updated August 10, 2026 · 12 min read · Editorial policy
The High Income Child Benefit Charge is an Income Tax charge linked to Child Benefit received by a family. It does not reduce each weekly payment at source: the higher-income partner can receive or repay some or all of the award through HMRC.
The linked calculator focuses on the two error-prone parts: adjusted net income and the higher-partner switch. It estimates current 2026/27 rules but does not decide entitlement, filing duties or whether a pension contribution is suitable.
The 2026/27 threshold and taper
HICBC starts when an individual's adjusted net income is above £60,000. For each full £200 above the threshold, one per cent of the Child Benefit award is charged. At £80,000 or more, the charge equals the full whole-pound award.
Finance Act rounding matters at the edges: a non-whole percentage is rounded down, and a non-whole-pound charge is rounded down. A smooth percentage graph can therefore differ by a few pounds from the statutory staircase.
2026/27 Child Benefit amounts
From 6 April 2026 the weekly rate is £27.05 for the eldest or only child and £17.90 for each additional child. A full 52-week year is £1,406.60 for one child and £930.80 for each additional child.
Actual entitlement can start or stop during the year and children can have different qualifying periods. The calculator uses one entered number of weeks for all children, so use HMRC's actual award when dates differ.
How to build adjusted net income
Begin with total taxable income before Personal Allowance. This can include employment and taxable benefits, self-employment profit, taxable pensions and state benefits, property income, savings interest, dividends and foreign income. Net salary arriving in the bank is not the starting point.
Deduct eligible items once. Relief-at-source pension payments and Gift Aid donations are grossed up: £800 paid is normally a £1,000 deduction. Contributions paid gross and certain trading losses can also reduce the figure. A salary-sacrifice contribution should not be deducted again if taxable salary is already reported after the sacrifice.
The higher-partner rule
HICBC is based on individual rather than combined income. If both partners exceed the threshold, the one with higher adjusted net income is responsible. Partner includes a spouse, civil partner or a person living with the claimant as if married, unless permanently separated.
Planning can change who is higher. If Person A falls from £72,000 to £62,000 after a pension payment while Person B remains at £68,000, Person B becomes the relevant higher earner and the charge is based on £68,000. Reducing only Person A to £60,000 cannot restore the full award in that example.
Worked example: two children and a pension payment
Two children produce £2,337.40 of Child Benefit for 52 weeks in 2026/27. With £70,000 adjusted net income and a partner on £55,000, the charge percentage is 50%. The whole-pound estimate is £1,168, leaving £1,169.40 after the charge.
A £4,000 net relief-at-source pension payment is grossed to £5,000 and reduces adjusted net income to £65,000. The charge percentage falls to 25%, the whole-pound charge to £584 and the retained award to £1,753.40. Another £4,000 net payment would be the relief-at-source equivalent of the remaining £5,000 gross reduction to £60,000, subject to pension limits and affordability.
Pension limits and wider tax are separate
The HICBC saving is not the complete return from a pension contribution. Higher-rate tax relief, salary-sacrifice Income Tax and NI, Scottish rates, savings and dividends can change the cash cost. Conversely, relevant earnings and pension annual-allowance rules can prevent the simple contribution shown from receiving the expected relief.
Use the pension salary-sacrifice tool for payroll tax and NI, then the carry-forward tool for the standard allowance, taper, MPAA and unused prior-year capacity. Scheme records and HMRC remain authoritative.
Keep the claim even when payments stop
A claimant can choose to receive Child Benefit and pay HICBC, or opt out of payments. Opting out is different from abandoning the claim. GOV.UK highlights National Insurance credits and automatic National Insurance numbers for children as reasons the underlying claim can still matter.
Current GOV.UK guidance allows eligible people to pay HICBC through PAYE or Self Assessment, with conditions. Use HMRC's service to confirm the route and deadlines rather than treating a calculator estimate as a filing instruction.
