The Child Benefit Tax Charge — formally known as the High Income Child Benefit Charge, or HICBC — is one of those areas of tax that genuinely surprises people. Not because it is complicated in principle, but because it arrives unexpectedly. A salary increase, a change in household circumstances, or simply not knowing that your partner claimed Child Benefit: any of these can land you with a bill from HMRC that you were not expecting.

The rules changed meaningfully from 6 April 2024, with the threshold rising to £60,000. That is good news for many families. But the charge still applies, the taper still bites, and thousands of people are still being penalised each year for missing their Self Assessment obligation. We see this come up regularly with clients, and in almost every case the problem was avoidable.

This post explains how the charge works under the current rules, what changed in 2024, and what you can actually do about it.

Child Benefit is a government payment made to families responsible for a child under 16 (or under 20 if they are in approved education or training). For the 2025-26 tax year, it is worth £25.60 per week for the eldest child and £16.95 per week for each additional child — so for a family with two children, that is over £2,200 a year.

The High Income Child Benefit Charge is effectively a clawback mechanism. If the higher earner in your household has an adjusted net income above £60,000, HMRC requires you to pay back some or all of that Child Benefit through the tax system. It is not a fine or a penalty — it is just how the policy is designed. But because it runs through Self Assessment rather than PAYE automatically, many people miss it entirely.

The charge falls on the higher earner in the household, even if it was their partner who claimed Child Benefit and received the payments. That asymmetry is where a lot of the confusion — and a lot of the unexpected bills — comes from. One partner may not even know the other’s income in detail, particularly if both are employees.

Adjusted net income is the figure that matters here, not your gross salary. It includes all taxable income — employment income, self-employment profits, rental income, savings interest, dividends — minus certain reliefs such as gift aid donations and pension contributions made outside of a workplace scheme.

The charge tapers in at a rate of 1% of the Child Benefit received for every £200 of adjusted net income above the £60,000 threshold. That means by the time adjusted net income reaches £80,000, the full amount of Child Benefit has been clawed back.

Here is what that looks like in practice:

• Adjusted net income of £60,000 — no charge applies
• Adjusted net income of £65,000 — charge equals 25% of Child Benefit received
• Adjusted net income of £70,000 — charge equals 50%
• Adjusted net income of £80,000 or above — charge equals 100% (all of it)

So a family with two children receiving around £2,200 in Child Benefit, where the higher earner has an adjusted net income of £70,000, would owe roughly £1,100 back to HMRC. That is a meaningful sum — and if they have not registered for Self Assessment, interest and penalties can be added on top.

It is also worth noting that if both partners have adjusted net income above £60,000, only the higher earner is responsible for paying the charge. You do not pay it twice.

The calculation uses adjusted net income for the tax year in question — so if your income fluctuates, your liability will too. A bonus in one year could push you into the charge unexpectedly, even if you have been safely below the threshold for the previous few years.

Before 6 April 2024, the HICBC threshold was £50,000 — and it had sat there, frozen, since the charge was introduced back in 2013. Over that period, wage growth and fiscal drag pulled a large number of families into scope who would never have been affected when the policy launched.

From 2024-25 onwards, the threshold was raised to £60,000, and the taper rate was halved — meaning the charge now phases out over a £20,000 range (from £60,000 to £80,000) rather than the previous £10,000 range. Both changes were welcome. Families earning between £50,000 and £60,000 no longer have a Child Benefit liability at all, and those earning between £60,000 and £80,000 face a smaller and more gradual charge than before.

The government has also consulted on eventually administering the charge on a household basis rather than an individual income basis, which would address the fundamental unfairness of two people each earning £59,000 having no charge, while one person earning £65,000 in the same type of household does. That reform has not been legislated as of the date of this post, so the individual income rules remain in force.

Following the 2024 changes, the number of families opting out of Child Benefit payments fell — suggesting many households that had previously stopped claiming have returned to take payments again. If you opted out and your income has since dropped below £80,000, it is worth reviewing whether you should opt back in.

Despite the threshold change, thousands of families continue to receive unexpected bills and penalties from HMRC each year. The reasons are fairly consistent when we look at the cases that come across our desk.

Not registering for Self Assessment

If you are employed and all your income is taxed through PAYE, you may never have filed a Self Assessment return. But the HICBC is not collected through PAYE automatically — it requires a return. HMRC will often catch up with you eventually through its data matching, but by then there may be interest on late payment and penalties for late filing on top of the original charge. Penalties for HICBC failures typically range from 10% to 30% of the tax due.

Not knowing your partner claimed

This is more common than people expect. One partner claims Child Benefit — which is entirely their right — while the other partner’s income is rising. If the higher earner does not know a claim is active, they may have no idea they have a tax liability.

A pay rise that tips you over the threshold

A promotion, a one-off bonus, or additional freelance income can push adjusted net income above £60,000 in a year where you assumed you were fine. Income in the form of benefits in kind can also count.

The common thread in all of these is that the charge requires proactive attention. It does not look after itself.

If your adjusted net income is above £60,000, there are legitimate steps you can take to reduce or eliminate the HICBC — and none of them involve anything unusual.

Pension contributions

This is the most straightforward lever. Personal pension contributions made outside of a workplace salary sacrifice arrangement are deducted from adjusted net income. So if your gross income is £68,000 and you make an £8,000 personal pension contribution, your adjusted net income falls to £60,000 — and your HICBC liability drops to nil. You also receive pension tax relief at your marginal rate. It is one of those genuinely win-win tax planning moves.

Gift Aid donations

Charitable donations made under Gift Aid are also deducted from adjusted net income when calculating the charge. If you donate to charity regularly, make sure those donations are properly recorded.

Opting out of Child Benefit payments

If your adjusted net income is reliably above £80,000, opting out of receiving the payments avoids the charge altogether. Crucially, you can still claim Child Benefit without receiving payments — this preserves your child’s National Insurance record and any entitlement to future state pension credits. Many families are unaware they can do this.

If your income is between £60,000 and £80,000, opting out means you lose the payment without gaining any net benefit — the right answer is usually to receive the payments, plan for the charge, and file a Self Assessment return.
