What is HICBC?
Child Benefit is a flat weekly amount paid to every parent regardless of income. £26.05 for the eldest child and £17.25 for each younger child in 2026/27. Since 2013, HMRC has clawed it back from higher-earning households via a separate income-tax charge: the High Income Child Benefit Charge.
From April 2024, the thresholds were doubled. The charge now starts at £60,000 of adjusted net income and reaches 100% (full clawback) at £80,000. So the £20,000 band between those two figures is where you progressively lose the benefit at 1% per £200 of income above £60,000.
The maths in detail
The clawback is 1% of the year's Child Benefit for every £200 of adjusted net income between £60,000 and £80,000. So:
- £60,000 or below. No charge. You keep all the Child Benefit.
- £70,000. 50% clawback. You keep half.
- £80,000 or above. 100% clawback. The charge equals the entire annual Child Benefit.
Above £80,000 the charge plateaus. Earning more does not make the charge bigger. So the £60k to £80k band is the painful zone where every extra £1 of income costs you 1/200th of your annual Child Benefit on top of normal income tax and NIC.
What is “adjusted net income”?
This is the tax-tech term that does all the work. It is roughly: total taxable income, minus pension contributions, minus Gift Aid donations (grossed up). What it includes:
- Salary, bonuses and any taxable benefits-in-kind.
- Self-employment profit.
- Rental income, dividends, savings interest above the allowance.
- Most pensions (state and private).
What it does not include:
- Gross personal pension contributions (relief at source or net pay).
- Salary sacrificed into a pension. It never hits taxable pay in the first place.
- Charitable donations (Gift Aid grossed up at 25%).
- Trading losses brought forward.
The escape: pension contributions
Adjusted net income is what triggers the charge. Anything that reduces ANI saves the charge. The single most powerful lever is a pension contribution.
- If you earn £72,000 and want to escape the charge entirely, you need to bring ANI to £60,000 or below. That is a £12,000 gross pension contribution.
- If salary sacrifice is available, that £12,000 goes in tax-free and NIC-free. Costs you about £6,960 of net pay.
- The £12,000 lands in your pension. The £1,350.96 of HICBC is wiped out. You also keep the value of any personal allowance you might have lost separately if you are heading towards £100k.
For a parent of two earning anywhere in the £60k to £80k zone, the effective marginal rate on the slice between £60k and £80k is roughly 40% (income tax) + 2% (NIC) + 5 to 6% (HICBC clawback). Somewhere around 47% to 48%. Not as brutal as the 60% trap, but a real penalty that pension contributions erase entirely.
Should I just stop claiming Child Benefit?
You can opt out of the cash payment but still register your child for Child Benefit. That is the right move if your income is going to be persistently above £80,000. You avoid the admin of paying the charge each year via Self Assessment.
But register for the benefit regardless. Registering protects:
- Your State Pension qualifying years (Class 3 NIC credits attach to the parent at home with the child).
- Your child's automatic enrolment in the National Insurance number system at age 16.
Failing to register costs more than the charge in the long run. Tick the “don't pay me” box, not the “don't register” box.
Common mistakes
- Assuming household income matters. It does not. Two earners on £55k each pay nothing. One earner on £80k pays the lot.
- Forgetting to register Self Assessment. If you owe HICBC, you must file Self Assessment by 31 January after the tax year. HMRC are increasingly aggressive about late-filing penalties for missed HICBC.
- Paying salary sacrifice but not telling HMRC. If your code still reflects pre-sacrifice salary, you might trigger the charge on paper. Update your personal tax account.
- Stacking with the 60% trap. If your income is heading towards £100k, you face HICBC and the personal allowance taper. The cumulative marginal rate between £100k and £125k for parents can exceed 70%. Pension sacrifice is even more valuable here.
Bottom line
HICBC is a clawback dressed up as a tax. It hits the highest earner's adjusted net income, not household income, and it is mostly avoidable with pension contributions. If your income lives between £60k and £80k and you have kids, redirecting some of your salary into pension is rarely not worth it. You keep the Child Benefit, you save income tax, you save NIC if you sacrifice, and the money grows tax-free until retirement.
