HICBC Explained: Child Benefit, the £60,000 Threshold and the Hidden Marginal Rate

Child Benefit is paid to the main carer, free of income tax at the point of receipt. For 2026/27:

If you or your partner has "adjusted net income" above £60,000, you pay back Child Benefit through the tax system. It's 1% of the benefit for every £200 of income over £60,000. At £80,000+ you lose 100% of it.

Only the higher earner in the couple is tested — if you earn £120k and your partner earns £20k, you're at full claw-back. If you each earn £59k (total £118k household), no HICBC applies.

The test isn't your gross salary — it's adjusted net income:

• Start with taxable income (employment, self-employment, rental, dividend, interest).
• Deduct: grossed-up pension contributions (non-relief-at-source), Gift Aid donations grossed up.
• Do NOT deduct: personal pension contributions that already got higher-rate relief via PAYE.
• Salary sacrifice for pension reduces gross income before this test — one of the most effective HICBC mitigations.

Between £60,000 and £80,000, a one-child family faces:

• Higher-rate income tax at 40%
• Employee NI at 2%
• HICBC claw-back of 1% of the annual benefit for every £200 of income, about 7 percentage points for one child

That adds up to about 49% on each extra pound across the £60k–£80k band for one child. The claw-back is about 12 percentage points for two children (about 54% in total) and about 16 points for three children (about 58% in total), and 9% more if you also repay a student loan. Each extra pound of earnings keeps much less than a pound.

Layering on the £100,000–£125,140 Personal Allowance taper creates one of the most distorted tax structures in the UK. Salary sacrifice into a pension often looks like the best single financial decision a family in this range can make. See our full salary sacrifice guide for the mechanics.

Yes — even if you'll pay it all back via HICBC. Two reasons:

1. State pension credits — claiming Child Benefit grants National Insurance credits for the non-working parent. Missing these can reduce your State Pension.
2. Automatic NI number for the child — claim triggers the child's NI number being issued at age 16 automatically.

You can tick "do not pay the benefit" while still submitting the claim. That avoids paying and clawing back while preserving the NI credit.

The higher-earning partner is responsible for paying the charge. You can pay it through Self Assessment, or ask HMRC to collect it through PAYE instead. You must use Self Assessment if you already need to file a return for another reason, such as self-employed income or savings and dividends, or if it is after 31 January following the tax year.

• UK pension allowances guide — the contribution limits that can help reduce adjusted income.
• GOV.UK: Child Benefit tax charge — the official HICBC guidance.
• GOV.UK: claim Child Benefit — the claim route even when you repay it.
• GOV.UK: Self Assessment returns — useful for reporting HICBC in the older collection method.

• Pension salary sacrifice — most effective. Reduces gross income, saves on tax+NI+HICBC simultaneously (see pension allowances).
• Gift Aid — charity donations get grossed up and reduce ANI.
• EV salary sacrifice — lowers gross salary, also dodges HICBC proportionally.
• Income splitting between spouses — if one earns £150k and the other £10k, restructuring income towards the lower earner (dividends, rental ownership) reduces HICBC.
• Top-slicing with bonus timing — agreeing with employer to defer bonus into a future tax year helps only if that year will be lower.
