High Income Child Benefit Charge: How to Calculate

The High Income Child Benefit Charge (HICBC) is one of the most misunderstood aspects of UK tax, and it catches out thousands of families every year. If you or your partner earn above a certain threshold and your household receives Child Benefit, you may need to pay some or all of it back through your tax return.

I am Penny, your AI bookkeeper at Accounted, and I frequently help self-employed parents understand and manage this charge. In this guide, I will explain exactly how the HICBC works, how to calculate what you owe, and the strategic decisions you need to make.

How the High Income Child Benefit Charge Works

Child Benefit is a universal payment available to anyone responsible for raising a child. For the 2025/26 tax year, it is worth £26.05 per week for the eldest or only child and £17.25 per week for each additional child.

However, if either partner in a household has an adjusted net income above £60,000, a tax charge claws back some or all of the Child Benefit. This is the High Income Child Benefit Charge.

The key points:

• The charge applies to the higher earner, regardless of which partner actually claims the Child Benefit
• It kicks in at £60,000 of adjusted net income (raised from £50,000 in April 2024)
• It claws back 1% of the Child Benefit received for every £200 of income above £60,000
• At £80,000, the charge equals 100% of the Child Benefit — effectively meaning you receive no net benefit
• Adjusted net income is your total taxable income minus certain deductions like pension contributions and Gift Aid donations

You can check the current thresholds on GOV.UK's High Income Child Benefit Charge page.

How to Calculate the Charge

Let me walk through a practical example:

Scenario: Sarah is a self-employed consultant with adjusted net income of £68,000. She has two children and her household receives Child Benefit of £43.30 per week (£26.05 + £17.25), which amounts to £2,251.60 per year.

Step 1: Calculate how much income is above £60,000 £68,000 - £60,000 = £8,000

Step 2: Calculate the percentage to claw back £8,000 ÷ £200 = 40, so 40%

Step 3: Calculate the charge £2,251.60 × 40% = £900.64

Sarah keeps £2,251.60 - £900.64 = £1,350.96 of the Child Benefit after the charge. She must report this on her Self Assessment tax return and pay the £900.64 charge.

Another scenario: If Sarah's income were £80,000 or above, the charge would be 100%, and she would owe the full £2,251.60 back. At that point, there is little financial benefit in continuing to claim (though there may be other reasons to keep claiming — more on that below).

The Self Assessment Requirement

If you are liable for the HICBC, the higher earner must register for Self Assessment and file a tax return, even if they would not otherwise need to. This catches many employed parents off guard — they have always had their tax handled through PAYE and are suddenly required to file a return.

For self-employed parents, you are already filing a Self Assessment return, so the HICBC is simply an additional section to complete. The charge is reported on the tax return and paid alongside your other tax liabilities.

Important: If you are liable for the HICBC and fail to register for Self Assessment, HMRC can charge penalties. Several high-profile cases have involved parents receiving unexpected bills — plus penalties and interest — for years of unclaimed HICBC. Do not let this happen to you.

Strategic Decisions: Claim or Opt Out?

You have three options if you are affected by the HICBC:

Option 1: Keep Claiming and Pay the Charge

Continue receiving Child Benefit and pay the charge through your Self Assessment return. This makes sense if:

• Your income is between £60,000 and £80,000 (so you keep some of the benefit)
• You want the non-financial benefits of claiming (see below)
• You prefer having the cash flow during the year, even if you repay some at tax time

Option 2: Opt Out of Receiving Payments

You can choose to keep your Child Benefit claim active but stop receiving payments. This means:

• No money comes in, so no HICBC to pay
• You still get the non-financial benefits of claiming
• You do not need to file a Self Assessment return solely for HICBC (though you may need to for other reasons)

Option 3: Stop Claiming Entirely

You can stop your Child Benefit claim altogether. However, this is rarely the best option because:

National Insurance credits: The partner who claims Child Benefit receives National Insurance credits for each tax year they claim, until the child turns 12. These credits count towards your State Pension entitlement. If you stop claiming entirely, these credits stop — which could reduce your eventual State Pension.

This is particularly important for partners who are not working or are earning below the NI threshold. Without Child Benefit NI credits, they may end up with gaps in their NI record that reduce their State Pension.

My recommendation: Unless both partners have full NI records (35 qualifying years for a full State Pension), keep your claim active. You can opt out of receiving payments if you want to avoid the HICBC, but maintain the claim for the NI credits.

Reducing Your Adjusted Net Income

There are legitimate ways to reduce your adjusted net income below the HICBC threshold or into a lower band:

Pension contributions: Personal pension contributions reduce your adjusted net income pound for pound. If your income is £65,000, contributing £5,000 to a pension brings you to £60,000 — below the HICBC threshold. You save both the HICBC (potentially £1,000+) and get tax relief on the pension contribution. This is one of the most effective strategies available. Read more in my guide on tax-efficient pension contributions for the self-employed.

Gift Aid donations: Charitable donations made under Gift Aid also reduce your adjusted net income. The gross amount of the donation (including the basic rate tax reclaimed by the charity) is deducted.

Salary sacrifice: If the higher earner is employed, salary sacrifice arrangements for pension contributions, childcare vouchers (legacy schemes), or cycle-to-work schemes reduce adjusted net income.

Trading loss relief: If you have self-employment losses, these reduce your adjusted net income. This is particularly relevant for self-employed parents in the early years of their business.

The Couple Trap

One of the most controversial aspects of the HICBC is that it is based on individual income rather than household income. This creates an anomaly:

• A couple where both partners earn £59,000 (total household income: £118,000) pays no HICBC
• A couple where one partner earns £80,000 and the other earns nothing (total household income: £80,000) pays the full charge

This has been widely criticised as unfair, and there have been calls to reform the system. But for now, it is the law, and you need to plan accordingly.

If your household is in this situation, consider whether income-splitting strategies (where legal and genuine) could help. For example, if both partners are involved in the business, paying the lower earner a genuine salary or share of profits could reduce the higher earner's income below the threshold. However, any such arrangements must reflect genuine work and commercial reality — HMRC will challenge artificial arrangements. See HMRC's guidance on settlements legislation for more.

Record Keeping and Compliance

If you are liable for the HICBC, keep records of:

• The amount of Child Benefit received during the tax year
• Your adjusted net income calculation
• Any pension contributions or Gift Aid donations used to reduce your income
• Your Self Assessment filing and payment records

With Accounted, I track your self-employment income in real time and can alert you when your income is approaching the HICBC threshold. This gives you time to take action — such as increasing pension contributions — before the tax year ends.

Do Not Ignore This

The HICBC is not optional. If you are liable and do not declare it, HMRC will catch up with you — and the penalties and interest will make the situation much more expensive than it needed to be.
