Child Benefit Tax Charge Explained UK (2026/27 Complete Guide)

A family with two children where one parent earns £70,000 loses over £1,100 in Child Benefit every year through a tax charge that many parents don't fully understand — and some don't even know exists.

The High Income Child Benefit Charge (HICBC) is one of the most disliked parts of the UK tax system. It's complex, it requires Self Assessment filing, and it can create an effective marginal tax rate of over 50% for parents in the affected income range.

But it's also one of the most avoidable charges in the UK tax system. Salary sacrifice can eliminate it entirely for many families.

This guide explains everything you need to know. If you also earn over £60,000 and want a broader tax reduction strategy, see our guide on how to reduce tax if you earn £60k.

What is Child Benefit?

Child Benefit is a government payment to parents or guardians responsible for a child under 16 (or under 20 if in approved education or training).

2026/27 rates:

• £26.05/week for the eldest or only child (£1,354/year)
• £17.25/week for each additional child (£897/year)

Child Benefit is paid regardless of income — but if either parent's Adjusted Net Income (ANI) exceeds £60,000, HMRC claws it back through the HICBC.

What is the High Income Child Benefit Charge?

The HICBC is a tax charge that reduces or eliminates the value of Child Benefit for higher earners. It was introduced in 2013 and reformed in 2024 to raise the threshold from £50,000 to £60,000.

How the taper works in 2026/27:

• Below £60,000 ANI: no charge, keep all Child Benefit
• £60,000 to £80,000 ANI: repay 1% of Child Benefit for every £200 above £60,000
• Above £80,000 ANI: repay 100% — effectively no Child Benefit

The charge is based on the higher earner's ANI, not household income. This means a couple where one partner earns £75,000 and the other earns £0 pays the charge, while a couple where both earn £59,000 (household income £118,000) pays nothing.

How much does the charge cost?

Example 1: One child, £70,000 income

• Child Benefit: £1,354/year
• Income above £60,000: £10,000
• Charge: £10,000 ÷ £200 × 1% × £1,354 = £677/year
• Net Child Benefit kept: £677

Example 2: Two children, £70,000 income

• Child Benefit: £2,251/year
• Income above £60,000: £10,000
• Charge: £10,000 ÷ £200 × 1% × £2,251 = £1,126/year
• Net Child Benefit kept: £1,125

Example 3: Two children, £80,000 income

• Child Benefit: £2,251/year
• Income above £60,000: £20,000
• Charge: £20,000 ÷ £200 × 1% × £2,251 = £2,251/year
• Net Child Benefit kept: £0

At £80,000 or above, you repay 100% of Child Benefit. You receive the payments but pay them all back through your tax return.

The effective marginal rate trap

For parents with children earning between £60,000 and £80,000, the effective marginal tax rate is significantly higher than the headline 40%.

For a parent with two children earning in this band:

• 40% income tax
• 2% National Insurance
• Approximately 11.3% effective HICBC rate (£2,251 over a £20,000 range)
• Total: approximately 53% effective marginal rate

Every £1 of salary sacrifice in this band saves approximately 53p — making it one of the most valuable tax planning opportunities available to UK employees.

How salary sacrifice eliminates the charge

The HICBC is based on your Adjusted Net Income — your gross income minus pension contributions made via salary sacrifice (and certain other deductions).

This means salary sacrifice directly reduces your ANI, potentially bringing you below the £60,000 threshold and eliminating the charge entirely.

Example: £68,000 salary, two children

The £8,000 sacrifice costs approximately £4,640 in take-home pay (after tax and NI savings) but delivers £5,002 in combined tax, NI, and Child Benefit savings. The sacrifice effectively pays for itself.

Example: £75,000 salary, two children

This parent wants to eliminate the HICBC entirely by bringing ANI to £60,000.

Required sacrifice: £15,000

The £15,000 sacrifice costs approximately £8,700 in take-home pay and delivers £8,551 in savings — plus £15,000 going into the pension. The effective cost of building a £15,000 pension pot is just £149.

The £80,000 cliff edge — a common mistake

Above £80,000, you repay 100% of Child Benefit. At this point, many parents choose to simply opt out of receiving Child Benefit payments. This is often a mistake.

Why you should still register for Child Benefit even if you opt out of payments:

1. NI credits — if you're not working, Child Benefit registration provides NI credits that count towards your State Pension. Without these, you may have gaps in your NI record.

2. Your child's NI number — registering for Child Benefit ensures your child automatically receives a National Insurance number at age 16.

3. Future changes — if your income drops below £80,000 in a future year, you can restart payments without reapplying.

You can opt out of receiving payments while keeping the registration active. This avoids the HICBC while preserving the other benefits.

The Self Assessment requirement

If your ANI exceeds £60,000 and you or your partner received Child Benefit, you must:

1. Register for Self Assessment
2. File a tax return each year
3. Pay the HICBC through your tax return

If you've been unaware of this requirement, HMRC can go back up to four years. It's better to come forward voluntarily — HMRC's Let Property Campaign and similar disclosure facilities offer reduced penalties for voluntary disclosure.

If you use salary sacrifice to bring your ANI to £60,000 or below, you may no longer need to file Self Assessment (unless you have other reasons to do so). See our Self Assessment guide for deadlines and what to include.

How to calculate how much to sacrifice

The target is to bring your ANI to £60,000 (or as close as possible).

Step 1: Identify your current ANI. This is your gross salary plus any other income (bonuses, savings interest, rental income) minus any existing pension contributions via salary sacrifice.

Step 2: Calculate the gap. If your ANI is £72,000, you need to sacrifice £12,000 to reach £60,000.

Step 3: Check the Annual Allowance. Your total pension contributions (employee + employer) cannot exceed £60,000/year. If you're already contributing significantly, check you have room.

Step 4: Use the TaxCal UK calculator to model the exact impact. Enter your salary, existing pension %, Child Benefit details, and adjust the sacrifice amount to see the combined effect.

What about the other parent?

The HICBC applies to the higher earner in the household. If both parents earn above £60,000, the charge applies to the one with the higher ANI.

If the lower earner's ANI is below £60,000 and the higher earner's is above, only the higher earner's ANI matters for the charge.

This creates an interesting planning opportunity: if both parents earn similar amounts and one is just above £60,000, a relatively small sacrifice can eliminate the charge entirely.

What this means for you

The HICBC is one of the most avoidable taxes in the UK system. Unlike income tax, which applies to all earnings, the HICBC only applies if your ANI exceeds a specific threshold — and salary sacrifice directly reduces that threshold.

For many families, the combination of income tax savings, NI savings, and HICBC elimination makes salary sacrifice the single most valuable financial decision they can make.

The TaxCal UK calculator includes a full Child Benefit module. Tick the Child Benefit box, enter the number of children, and the calculator shows your exact HICBC position and how sacrifice affects it.

Step-by-step action plan

1. Check your ANI — use the calculator to see your current Adjusted Net Income
2. Calculate the charge — see how much HICBC you're currently paying
3. Model the sacrifice — adjust the sacrifice amount to see the combined savings
4. Contact HR — request an increase in salary sacrifice pension contributions
5. Register for Self Assessment — if you haven't already and your ANI exceeds £60,000
6. Review annually — your ANI changes each year; review your sacrifice amount at the start of each tax year

Frequently asked questions

Does the HICBC apply if my partner earns over £60,000 but I don't?

Yes. The charge applies to whichever partner has the higher ANI. If your partner earns £70,000 and you earn £30,000, the charge is based on your partner's income. Your partner would need to sacrifice salary to reduce their ANI.

Can I claim Child Benefit for a child who lives with me but isn't mine?

Yes, if you're responsible for the child. The rules are based on who is responsible for the child, not biological parenthood.

What if I only recently started earning over £60,000?

The charge applies from the tax year in which your ANI first exceeds £60,000. If this is your first year above the threshold, register for Self Assessment and pay the charge for that year. Going forward, use salary sacrifice to manage your ANI.

Is the £60,000 threshold going to change?

The threshold was raised from £50,000 to £60,000 in April 2024. There are no announced plans to change it further, but it's worth checking at the start of each tax year.

FAQ

What if both partners earn over £60,000?

The charge applies to the partner with the higher ANI. If both earn over £60,000, only the higher earner's income determines the charge amount.

Is the £60,000 threshold based on gross salary or Adjusted Net Income?

Adjusted Net Income. Salary sacrifice pension contributions reduce ANI, so your gross salary can be above £60,000 while your ANI is below it — eliminating the charge.

Do I need to register for Child Benefit even if I won't receive payments?

Yes. Registering protects your NI record if you are not working, and ensures your child automatically receives a National Insurance number at age 16.

Can I claim back HICBC I've already paid if I now use salary sacrifice?

No. The charge applies to each tax year based on that year's ANI. Salary sacrifice reduces future charges but does not affect past years.

What is the maximum Child Benefit for 2026/27?

£1,354/year for one child, £2,251/year for two children, £3,148/year for three children.
