Child Benefit High Income Tax Charge (HICBC) Calculator 2025/26

From April 2024, the High Income Child Benefit Tax Charge threshold rose from £50,000 to £60,000. The charge is fully tapered away by £80,000. This calculator shows whether you owe the charge — and whether it's worth claiming Child Benefit at all.

Child Benefit and the High Income Child Benefit Charge 2025

Child Benefit is a universal payment for families with children under 16 (or under 20 if in approved education or training). For 2025/26, rates are £26.05 per week for the eldest child and £17.25 per week for each additional child. A family with two children receives £2,246.60 per year. The High Income Child Benefit Charge (HICBC) claws back this benefit when the higher earner in the household exceeds the income threshold.

HICBC Thresholds — April 2024 Changes

The HICBC underwent its most significant reform since introduction in 2013. From April 2024:

  • Below £60,000: No HICBC — keep the full Child Benefit amount
  • £60,001–£80,000: HICBC at 1% of Child Benefit for every £200 above £60,000
  • Over £80,000: Full HICBC — the charge equals the full Child Benefit (no net benefit from claiming)

The threshold increase from £50,000 to £60,000 brought approximately 170,000 families back into eligibility. A family with two children where the higher earner earns £65,000 (£5,000 above the new threshold) faces a 25% charge — keeping 75% of Child Benefit, a net annual benefit of approximately £1,685.

Household Income Assessment from April 2026

The government announced that from April 2026, the HICBC will be assessed on combined household income rather than individual income. This ends the significant unfairness where two earners at £59,000 each (£118,000 combined) paid no charge, while a single earner at £80,000 lost all benefit. The reform will benefit single-earner households but may increase the charge for some dual-income couples above the combined household threshold.

Why You Should Claim Child Benefit Even If You Pay the Full Charge

For most families facing the full HICBC, claiming remains worthwhile:

  • NI credits: The claiming parent receives NI credits counting toward their State Pension — particularly valuable for a non-working or part-time parent who would otherwise have NI gaps
  • Child's NI number: HMRC automatically issues a National Insurance number when children registered for Child Benefit turn 16
  • Administrative simplicity: Easier to claim and pay the charge via Self Assessment than to retrospectively register for NI credits

Using Pension Contributions to Reduce the HICBC

Pension contributions reduce adjusted net income — the figure used to calculate the HICBC. If you earn £65,000 and make £6,000 personal pension contributions, your adjusted net income falls to £59,000 (below the £60,000 threshold), eliminating the charge entirely. This is one of the most effective ways to reduce HICBC for those earning just above the threshold. Salary sacrifice pension contributions are even more efficient as they reduce gross pay before tax and NI are calculated.

Child Benefit Rates and the Two-Child Limit

No additional Child Benefit is paid for a third or subsequent child born on or after 6 April 2017, unless a limited exception applies (multiple births, adoption, non-consensual conception). This two-child limit also applies to the child element of Universal Credit and Child Tax Credit. Claims are made by completing Form CH2 online or by post — claims for newborns cannot be backdated more than three months, so apply promptly after birth.

Child Benefit and Universal Credit Interaction

Child Benefit and Universal Credit are assessed completely separately. Receiving Child Benefit does not reduce your Universal Credit entitlement — they do not interact in the way that some legacy benefits did. You should claim both if eligible for both. However, the HICBC only applies to Child Benefit, not to the child element of Universal Credit. A household receiving Universal Credit with a child element faces no HICBC-style clawback from UC regardless of income — though UC itself phases out under the earnings taper.

Future Household Assessment from April 2026

The planned shift to household income assessment for the HICBC from April 2026 will require HMRC to assess both partners' incomes together. The exact mechanism is still being developed but will likely require both partners to file information via Self Assessment or a new digital service. Currently, only the higher earner files a Self Assessment return for HICBC purposes. From 2026, couples with combined income above the household threshold will need to consider how they manage information reporting together. HMRC has indicated it will provide guidance and a new process before the change takes effect.

The HICBC can often be legitimately reduced through careful income planning. Salary sacrifice into a workplace pension, Gift Aid donations, and trading losses from self-employment can all reduce adjusted net income toward or below the £60,000 threshold. For couples where both partners work, ensuring the lower earner claims Child Benefit (not the higher earner) ensures the HICBC is assessed on the lower of the two incomes, minimising the overall charge.

Frequently Asked Questions

Do I need to register for Self Assessment to pay the HICBC?+
Yes. The higher earner must register for Self Assessment and complete a tax return each year if the household is claiming Child Benefit and either partner earns over £60,000. HMRC does not collect the HICBC through the PAYE tax code — it must be declared and paid via Self Assessment. Failure to register can result in penalties in addition to the HICBC itself.
What if both partners earn between £60,000 and £80,000?+
Currently the HICBC is assessed on the higher earner's individual income only. If both partners earn £65,000, the HICBC is calculated based on the higher earner's £65,000. From April 2026, the planned household income assessment will change this — both incomes will be combined, which will benefit single-earner households at the same total income.
Can I opt out of Child Benefit to avoid the HICBC?+
You can choose not to receive Child Benefit payments while still registering for it (a "zero payment claim"). This protects the NI credits and ensures your child gets their NI number automatically at 16. You can restart payments at any time by contacting HMRC. This approach is recommended for families where the higher earner is above £80,000 — they gain the NI credit protection without the administrative burden of paying back the full charge via Self Assessment.
Does Child Benefit affect mortgage affordability assessments?+
Some mortgage lenders will include Child Benefit as income when assessing mortgage affordability, while others exclude it or treat it as temporary income. Lenders who include it may increase the mortgage amount available to you. If your Child Benefit is being reduced by the HICBC, some lenders use the net benefit (after HICBC) rather than the gross amount. Check with your mortgage broker or lender directly about how they treat Child Benefit income in affordability calculations.
