Are You Paying the High Income Child Benefit Charge — and Do You Even Know It?

HMRC is expecting around 35,000 more families to become liable for the High Income Child Benefit Charge (HICBC) over the next three years. The reason isn't complicated — frozen tax thresholds combined with rising household incomes is quietly dragging more people into scope without them realising it. Salaries go up, thresholds stay still, and suddenly you're liable for a charge you didn't even know existed.

If you or your partner claim Child Benefit and one of you earns over £60,000, this affects you. Here's a straightforward breakdown of how it works, what you need to do, and how to avoid getting caught out.

What is the High Income Child Benefit Charge?

Child Benefit is a payment made to families responsible for raising a child. As of 2024/25, the standard rate is £25.60 per week for the eldest child, with additional amounts for any further children.

The High Income Child Benefit Charge is HMRC's way of clawing that benefit back from households where one partner earns above a certain threshold. It's been around since 2013, but the threshold has changed over the years and many people don't realise they've crossed it.

A few things are worth being clear on from the outset. First, it's a household charge — it doesn't matter whose name the benefit is claimed in, or which bank account the money goes into. If one partner earns above the threshold, that person is responsible for repaying the charge. Second, it applies to both married couples and couples living together as if married. And third, it's based on individual income, not combined household income — so a couple where both partners earn £55,000 would face no charge at all, while a couple where one earns £80,000 and the other earns nothing would face a full repayment.

What are the current thresholds?

For 2024/25 onwards, the threshold is £60,000. Once one partner's income exceeds that, the higher earner begins repaying 1% of the household's Child Benefit for every £200 earned above it. By the time income reaches £80,000, the charge equals 100% of the benefit received — meaning the family effectively gets nothing.

It's worth noting that the rules were different before April 2024. In 2023/24 and earlier years, the threshold was £50,000, and the taper was steeper — 1% per £100 over the threshold, meaning the full clawback kicked in at £60,000. If you were earning between £50,000 and £60,000 in those earlier years, you may have been liable without realising it.

How much will you actually pay?

Let's put some numbers on it to make it concrete.

In 2024/25, Child Benefit for one child is worth approximately £1,331 for the full year. If your income is £65,000 — that's £5,000 over the £60,000 threshold — you'd divide that £5,000 by £200, giving you 25. You'd therefore repay 25% of your Child Benefit, which works out at around £333.

If your income is £70,000, you'd repay 50% — around £666. At £75,000, 75% — around £998. At £80,000 or above, you repay the full amount.

If you have more than one child, the benefit amounts are higher, so the repayment amounts scale accordingly. For two children, the annual benefit is worth around £2,212 in 2024/25, so the numbers involved become more significant.

How and when do you pay it?

The vast majority of people pay the HICBC through their Self Assessment tax return. If you've crossed the threshold for the first time, you'll need to register for Self Assessment for that tax year by 5 October the year after it ends. Your return and any tax due must then be filed and paid by 31 January following the end of the tax year.

So if you first exceeded £60,000 in the 2025/26 tax year, you'd need to register for Self Assessment by 5 October 2026, and file and pay by 31 January 2027.

In certain circumstances it's possible to have the charge collected through your PAYE tax code instead, which can make it simpler to manage, but this isn't an option for everyone and specific conditions need to be met.

Should you just opt out of Child Benefit?

You can opt out of receiving Child Benefit payments at any time — and for some people, it makes sense to do so.

If your income is already above £80,000, you're repaying 100% of the benefit anyway. In that situation, continuing to claim just creates extra admin — you receive the money, then pay it all back through Self Assessment. Opting out removes that back-and-forth entirely.

If your income is between £60,000 and £80,000, the decision is less clear-cut because you're only repaying part of the benefit, so you're still better off overall than if you hadn't claimed at all. But it's worth weighing that against the hassle of registering for Self Assessment if you wouldn't otherwise need to be.

One important thing to flag — even if you opt out of receiving payments, it's worth keeping the Child Benefit claim open in name. Claiming Child Benefit (even if payments are paused) protects your National Insurance record and can count towards your State Pension entitlement. This matters particularly for a partner who isn't working or is on a lower income.

What if you've separated from your partner?

This is where things can get genuinely complicated, and it's an area where a lot of people get caught out.

HICBC applies to couples who are married or living together as if married. If you separate partway through a tax year, you can apportion the charge — meaning you'd only be liable for the Child Benefit received between the start of the tax year and the date of separation, not the full year's worth.

However, HMRC doesn't apply a straightforward legal test for when separation occurred. In practice, the date of separation is generally treated as the point at which both parties accepted the relationship was permanently over. Supporting evidence — such as separation of finances, changes to living arrangements, or telling friends and family — can help establish the date if it's ever questioned.

There's also a situation that many people find genuinely unfair. If a higher earner separates from their partner but continues to financially support the household where the child lives — even contributing more than the value of the Child Benefit itself — they can still be liable for the HICBC. The fact that the couple no longer share a home, or that the higher earner is already contributing to the child's upbringing, makes no difference to HMRC's calculation. It's a frustrating aspect of the rules, and one worth being aware of if your circumstances have changed.

What if you've missed this in previous years?

This is more common than people realise. The HICBC has been in place since 2013, the threshold has changed over time, and plenty of people have simply never known they were caught by it — particularly if they weren't already filing Self Assessment returns for any other reason.

HMRC has been increasingly active in this area and has been sending out nudge letters to taxpayers who they believe may owe the charge. If you've received one of these letters, take it seriously. You should respond within the timeframe given and, ideally, seek professional advice before you do so — especially if there are historic years involved or the position is complex.

If you think you may have underpaid over several years, it's possible to come forward voluntarily using HMRC's Digital Disclosure Service. Making a voluntary disclosure is nearly always the better outcome compared to HMRC opening an enquiry into your affairs. It typically results in lower penalties and demonstrates good faith. The window for going back and amending past returns is limited — generally one year from the 31 January following the end of the relevant tax year — so if you've been non-compliant for some time, a formal disclosure may be the only route available.

What should you do if you've just hit the threshold?

If this is the first year your income has exceeded £60,000, here's what you need to do:

Register for Self Assessment for the tax year in which you first crossed the threshold. You must do this by 5 October following the end of that tax year. File your Self Assessment return and pay any HICBC due by 31 January the year after that. If your income is consistently above £80,000 and you're still claiming Child Benefit, consider opting out to simplify things going forward — but as noted above, keep the claim open if it's protecting your NI record.
