High Income Child Benefit Charge Calculator UK 2025/26
Use our free High Income Child Benefit Charge (HICBC) Calculator to work out if you’ll have to repay some or all of your Child Benefit through this special tax charge. This tool applies the 2025/26 income thresholds and calculates your exact HICBC liability.
What is the High Income Child Benefit Charge?
The High Income Child Benefit Charge (HICBC) is a special tax charge that claws back Child Benefit from higher earners. Introduced in January 2013, it affects households where one partner earns over £50,000 per year.
The charge works by gradually reducing your effective Child Benefit until it’s completely recovered when the highest earner reaches £60,000. Unlike other taxes, it’s paid through Self Assessment rather than being deducted from your salary.
HICBC Income Thresholds 2025/26
| Highest Earner’s Income | HICBC Charge | Child Benefit Kept |
|---|---|---|
| Under £50,000 | £0 | 100% |
| £50,000 – £60,000 | 1% of benefit per £100 over £50k | 100% to 0% |
| £60,000 or more | 100% of Child Benefit | 0% |
Example: If the highest earner makes £55,000 and you receive £2,375 Child Benefit annually, the charge would be 50% (£1,187.50), leaving you with £1,187.50 net benefit.
How the HICBC Works
- Identify the highest earner: Compare both partners’ incomes — the one earning more triggers the charge
- Check the threshold: If income is under £50,000, no charge applies
- Calculate excess: Subtract £50,000 from the highest income
- Apply 1% rule: For every £100 over £50,000, you lose 1% of Child Benefit
- Register for Self Assessment: If charge applies, you must declare it to HMRC
Who Pays the Charge?
The HICBC is paid by the highest earner, not the person who claims Child Benefit. This matters significantly for couples where:
- One partner earns over £50,000 and the other doesn’t — the higher earner pays
- Both partners earn over £50,000 — the one earning more pays
- You’re a single parent earning over £50,000 — you pay the charge
- You’re separated but still living together — each partner’s income is assessed separately
Note: If your partner claims Child Benefit and you’re the higher earner, you’re responsible for paying the charge even though they receive the payments.
Should You Claim Child Benefit Anyway?
National Insurance Credits
Even if you don’t keep the money due to HICBC, claiming Child Benefit gives your partner National Insurance credits towards their State Pension. This is especially valuable if they’re not working or earning less than £12,570 annually. You can opt out of receiving payments while still registering a claim.
Automatic Childcare Support
Claiming Child Benefit ensures your children are automatically enrolled for their National Insurance number at age 16, making it easier for them to start working. It also helps establish parental responsibility for certain benefits and allowances later in life.
Partial Charges Might Be Worth It
If the charge is less than 100% (income between £50k-£60k), you still keep some money. For example, at £52,500 income you’d only pay 25% of the benefit back, keeping 75%. This might be worthwhile compared to losing everything by not claiming.
Self Assessment Registration
You must register for Self Assessment and file a tax return if:
- You receive Child Benefit AND the highest earner earns over £50,000
- You haven’t filed a Self Assessment return in the last 5 years
- Your HICBC charge is greater than £0 for any part of the tax year
Important deadline: Register by 5 October after the end of the tax year in which the charge arose. For 2025/26, register by 5 October 2026.
Worked Examples
Example 1: Income £50,000 exactly
Highest earner: £50,000. Child Benefit: £2,375. Excess over threshold: £0. Percentage charge: 0%. HICBC due: £0. Net benefit: £2,375. No Self Assessment required.
Example 2: Income £55,000
Highest earner: £55,000. Child Benefit: £2,375. Excess: £5,000. Percentage: 50% (£5,000 ÷ £100 × 1%). HICBC due: £1,187.50. Net benefit: £1,187.50. Self Assessment required.
Example 3: Income £60,000+
Highest earner: £65,000. Child Benefit: £2,375. Excess: £15,000. Percentage: 100% (capped). HICBC due: £2,375. Net benefit: £0. Effectively you keep nothing. Self Assessment required.
Example 4: Partners earning £48,000 and £52,000
Highest earner: £52,000. Child Benefit: £2,375. Excess: £2,000. Percentage: 20% (£2,000 ÷ £100 × 1%). HICBC due: £475. Net benefit: £1,900. The £52,000 earner pays the charge, not the £48,000 earner.
Opting Out vs Paying the Charge
You have three main options if HICBC applies:
| Option | Pros | Cons |
|---|---|---|
| Continue claiming and pay HICBC | Keep partial benefit, get NI credits | Must file Self Assessment |
| Opt out of receiving payments | Still get NI credits, no paperwork | Receive £0 benefit |
| Stop claiming entirely | No Self Assessment needed | Lose benefit and NI credits |
Adjustments and Allowances
Pension Contributions
Making pension contributions can reduce your adjusted net income below the £50,000 threshold. For example, contributing £2,000 gross to a workplace pension lowers your taxable income, potentially eliminating your HICBC liability.
Gift Aid Donations
Charitable donations under Gift Aid also reduce your adjusted net income. If you donate £1,000 gross to charity, this lowers your income for HICBC purposes by the same amount.
Trading Allowance
If you have side income, the £1,000 trading allowance means the first £1,000 of miscellaneous income isn’t counted towards HICBC thresholds.
Frequently Asked Questions
Does my partner’s Child Benefit claim affect my income tax band?
No. The HICBC is a separate charge and doesn’t change your Income Tax or National Insurance calculations. You still pay tax at your normal rates based on income bands. HICBC is reported separately through Self Assessment.
What income counts towards the £50,000 threshold?
It’s your “adjusted net income” — total taxable income before personal allowances, including salary, bonuses, pensions, rental income, savings interest, and dividends. It excludes Child Benefit itself, tax-free bonuses, and certain benefits like the State Pension.
Can I split Child Benefit between partners to avoid HICBC?
No. HMRC treats the highest earner as liable regardless of who receives the payments. Splitting claims or having your lower-earning partner claim doesn’t avoid the charge if you’re the highest earner.
Does the threshold change with inflation?
As of 2025/26, the thresholds remain frozen at £50,000 and £60,000. There have been no increases since the charge was introduced in 2013, meaning more families are caught by “fiscal drag” as salaries rise with inflation.
What if my income fluctuates during the year?
HICBC is calculated on your actual annual income for the tax year (6 April to 5 April). If you earn £48,000 most of the year but get a big bonus pushing you over £50,000, you’ll pay the charge for that year. Adjustments can be made in future returns.
How much Child Benefit do I get per child?
For 2025/26: First child receives £25.20 per week (£1,310.40 annually). Each additional child receives £16.70 per week (£868.40 annually). Maximum annual amounts: 1 child = £1,310.40, 2 children = £2,178.80, 3 children = £3,047.20, 4 children = £3,915.60.
Can I opt back into receiving payments later?
Yes. You can stop receiving Child Benefit now and restart later if your income drops below £50,000. Contact the Child Benefit Office to pause or resume payments. Your claim remains active throughout, preserving NI credits.
Do lone parents face different rules?
No. Single parents are treated the same as couples. If you’re a sole applicant earning over £50,000, the HICBC applies to your Child Benefit. There’s no higher threshold or exemption for lone parents.
What happens if I forget to declare HICBC?
HMRC receives data from employers about earnings. If you don’t register for Self Assessment, they may discover your income and contact you. Late registration penalties start at £100 and increase for each month overdue. Interest accrues on unpaid charges.
