Child Benefit Tax Trap — How to Avoid the High Income Child Benefit Charge (2025)
Child Benefit is worth up to £1,331 per year for a first child — but if either parent earns above £60,000, you face a tax charge that claws it all back. Get it wrong and you can find yourself with an unexpected HMRC bill, penalties for missing a Self Assessment return, and years of back-payments to make. This guide explains the rules clearly, including the significant April 2024 changes, and the legitimate ways to reduce or eliminate the charge.
What Is Child Benefit?
Child Benefit is a government payment made to the person responsible for bringing up a child under 16, or under 20 if the child is in approved full-time education or training. It is paid by HMRC directly to the claimant — usually the higher-earning parent elects the other to claim — and can be paid for any number of children. There is no means test to receive Child Benefit itself; anyone can claim it regardless of income.
Child Benefit rates from April 2025 are:
| Child | Weekly Rate | Annual Amount |
|---|---|---|
| Eldest or only child | £25.60 | £1,331.20 |
| Each additional child | £16.95 | £881.40 |
For a family with two children, that is £2,212.60 per year — a meaningful sum, particularly for families where one parent is not working or earns less. But if either parent has an "adjusted net income" above £60,000, the High Income Child Benefit Charge begins to claw it back.
What Is the High Income Child Benefit Charge?
The High Income Child Benefit Charge (HICBC) is a tax charge imposed on the higher earner in a household where Child Benefit is received, if that person's adjusted net income exceeds £60,000 (from 6 April 2024 — previously £50,000). The charge is calculated as a percentage of the Child Benefit received, rising gradually until it equals 100% of the benefit at £80,000 income (previously £60,000).
How the Charge Is Calculated
For every £200 of adjusted net income above £60,000, 1% of the Child Benefit received is clawed back. So:
- At £60,000 — no charge. Keep all Child Benefit.
- At £65,000 — 25% clawback (£65,000 − £60,000 = £5,000 ÷ £200 = 25%)
- At £70,000 — 50% clawback
- At £75,000 — 75% clawback
- At £80,000 or above — 100% clawback. You effectively keep nothing from Child Benefit.
The April 2024 Threshold Increase — What Changed
Until 5 April 2024, the HICBC began at £50,000 and reached 100% clawback at £60,000. This threshold had not been increased since the charge was introduced in 2013, meaning that millions more families had been drawn into paying it due to wage growth and fiscal drag. In the 2024 Spring Budget, the government raised the lower threshold to £60,000 and the upper (full clawback) threshold to £80,000.
This change benefited an estimated 485,000 families who were previously subject to a partial or full clawback but are now unaffected. Families where the higher earner earns between £60,000 and £80,000 now receive some benefit where previously they received none, or see a reduced charge. Families where the higher earner earns £80,000 or more continue to face a full 100% clawback.
The government has also announced plans to move to a household-based system — where the HICBC is calculated on both partners' combined income rather than the single higher earner — but no implementation date has been confirmed as of May 2025. The current individual-income system continues to apply.
What Is "Adjusted Net Income"?
The charge is based on "adjusted net income" — not gross salary. This is a specific HMRC definition and understanding it is key to managing the charge. Adjusted net income starts with total income (salary, self-employment profits, rental income, dividends, savings interest) and then deducts:
- Pension contributions paid to a personal or workplace pension (gross amount — including tax relief if using relief at source)
- Gift Aid donations (grossed up at basic rate)
- Trading losses
- Some business expenditure for employees
This means a person with a gross salary of £68,000 who pays £10,000 per year into a pension has an adjusted net income of £58,000 — below the £60,000 threshold — and avoids the charge entirely. This is the most powerful legitimate strategy for avoiding HICBC.
The "Trap" — Why Families Get Caught Out
Several features of the HICBC catch families by surprise:
It Applies to the Individual Earner, Not the Household
The HICBC bites on the income of the higher earner in the household — even if the claimant is the other parent. A couple where one partner earns £75,000 and the other earns £30,000 face the charge based on the £75,000 income, even though the £30,000-earning partner claims the benefit. A couple where both partners earn £55,000 each — total household income £110,000 — pay no charge at all.
It Creates a Tax Rate Above 60% at the Margin
For higher-rate taxpayers earning between £60,000 and £80,000 with children, the combined effect of 40% income tax, 2% National Insurance, and the HICBC can create a marginal tax rate of over 60% on earnings in that band. Every additional £100 of income above £60,000 costs not only tax and NI but also 50p per week of Child Benefit for each child — creating a strong disincentive to earn slightly over the threshold.
Self Assessment Is Required — And Often Missed
The HICBC must be declared and paid through Self Assessment. If you are employed and have never filed a tax return, you need to register for Self Assessment and file a return for every tax year you were subject to the charge — going back up to four years. Thousands of families have received unexpected HMRC demands, plus penalties and interest, because they were not aware of this obligation.
Strategies to Reduce or Eliminate the HICBC
Increase Pension Contributions
The single most effective strategy is to increase pension contributions until adjusted net income falls below the relevant threshold. Every £1 contributed to a pension reduces adjusted net income by £1. For someone earning £70,000, contributions of £10,000 per year reduce adjusted net income to £60,000, eliminating the charge entirely. The pension contribution also attracts 40% tax relief (for a higher-rate taxpayer), making it extremely tax-efficient.
Contributions can be made as employee contributions through payroll (which may also save National Insurance via salary sacrifice — see below), as personal contributions to a SIPP, or as employer contributions. All reduce adjusted net income equally.
Use Gift Aid
Charitable donations made through Gift Aid reduce adjusted net income by the grossed-up amount. A £800 cash Gift Aid donation reduces adjusted net income by £1,000. For those close to the £60,000 threshold, this can tip the balance — and the charity also benefits from a meaningful donation.
Salary Sacrifice Arrangements
Salary sacrifice — arranging for your employer to pay pension contributions or other benefits (childcare vouchers, cycle to work, electric vehicles) from your pre-tax salary — reduces your gross pay and therefore your adjusted net income. For someone earning £63,000, salary-sacrificing £4,000 into a pension brings adjusted net income to £59,000, below the threshold. Unlike personal pension contributions, salary sacrifice also saves National Insurance contributions.
The "Opt Out" Strategy — Stop Claiming, Keep NI Credits
If the higher earner in the household earns significantly above £80,000, the entire Child Benefit is clawed back in tax. In this case, there is no financial benefit to continuing to receive Child Benefit — but there are two reasons to continue claiming:
- National Insurance credits — a parent who is not in paid employment and claims Child Benefit receives National Insurance credits that protect their State Pension entitlement. If Child Benefit is simply not claimed, these NI credits are lost.
- Child's NI number — children of Child Benefit claimants automatically receive a National Insurance number shortly before their 16th birthday. Children whose parents did not claim Child Benefit may need to apply separately.
The solution is to claim Child Benefit but elect to receive zero payments — this is done on the Child Benefit claim form or by contacting HMRC. Electing to receive no payments preserves the NI credits and the NI number without creating a HICBC obligation.
Claiming Back Overpaid HICBC
Following the April 2024 threshold increase, some families who were paying HICBC in 2023/24 (on incomes between £50,000 and £60,000) found they had overpaid for part of the tax year. HMRC adjusted the calculation for 2023/24 pro-rata to reflect the new thresholds applying from 6 April 2024. Families who had previously opted out of receiving Child Benefit entirely, due to earning above £50,000, may now wish to restart their claim if their income is below £80,000.
HMRC automatically adjusts Self Assessment calculations to reflect the new thresholds. If you have not yet filed your 2023/24 or 2024/25 Self Assessment return, include the correct Child Benefit income and HICBC calculation based on the new thresholds. If you overpaid in prior years, a correction or repayment claim may be possible within the relevant time limits.
Step-by-Step: Managing the HICBC
- Calculate your adjusted net income — start with your gross income and deduct pension contributions, Gift Aid, and other allowable deductions to see whether you are above or below £60,000.
- Work out your charge — if above £60,000, use the calculator to determine what percentage of your Child Benefit will be clawed back.
- Consider pension top-up — if you are within £10,000–£20,000 of the £60,000 threshold, consider whether increasing pension contributions could bring you below it.
- Register for Self Assessment if needed — if you are subject to the charge, register at gov.uk. Do this promptly — penalties for late registration apply.
- File your return and pay the charge — HICBC must be declared on your Self Assessment return each year and paid by 31 January following the end of the tax year.
- Opt out of payments if above £80,000 — if your income is above the full clawback threshold and is unlikely to fall below it, elect to receive zero payments while preserving your NI credits.
