UK welfare · HICBC FY 2026/27
Model the High Income Child Benefit Charge under the active HMRC framework. Drop in your gross income and the calculator will surface your Adjusted Net Income, the applied tax-charge percentage against your annual benefit, the net cash retained, and whether you can collect the bill via your PAYE tax code instead of Self Assessment.
Engine note · HICBC clawback walked in 1% per £200 increments in integer pence — no rounding drift across the £60k–£80k taper, no telemetry.
Project your High Income Child Benefit Charge exposure under the active HMRC framework. Drop in a monthly pension or salary sacrifice figure to compress your Adjusted Net Income back below the trigger threshold and watch the clawback evaporate in real time.
2024/25 onwards uses the £60k–£80k taper at £200/1%. 2023/24 still uses the legacy £50k–£60k taper at £100/1%.
Eldest uses the higher weekly rate; siblings drop to the additional-child rate.
= 52 × £44.95 per week.
ANI = gross − sacrifice − Gift Aid.
Below threshold = 0% charge · above cap = 100% charge.
Annualises to £0 — pulled straight off your ANI before the taper is applied.
Child Benefit serves as a vital welfare baseline for millions of families across the United Kingdom, delivering flat weekly cash allocations to assist with the structural costs of raising children. Under the High Income Child Benefit Charge (HICBC) provisions, however, this universal benefit transforms into a highly targeted tax clawback the moment the highest-earning partner in a household crosses specific income boundaries.
Understanding how your individual Adjusted Net Income interacts with the statutory taper framework is essential for preventing unexpected end-of-year tax bills and optimising your household's overall financial efficiency.
A critical aspect of the HICBC is that it operates purely on an individual income basis, completely independent of combined household earnings. While prior legislative plans aimed to shift the entire framework to a combined household-income assessment, the government formally cancelled those proposed reforms.
This baseline structure creates a distinct financial paradox across the UK tax code. A dual-income household where both partners earn £59,500 each (combined £119,000) retains 100% of their Child Benefit completely tax-free, as neither individual crosses the statutory trigger point. Conversely, a single-earner household where one parent earns £80,000 while the other has zero income faces a full 100% tax clawback. The charge is always legally levied against the partner with the highest individual ANI, regardless of who physically submits the claim or receives the cash into their account.
For the active 2026/27 tax year, the clawback threshold begins at an individual Adjusted Net Income of £60,000. Below this line, your benefit is completely safe. The moment your ANI moves past the threshold, the benefit is systematically withdrawn using a flat taper formula:
Tax charge percentage = (Adjusted Net Income − £60,000) ÷ £200 × 1%.
This slower taper means that Child Benefit is completely wiped out once individual income reaches £80,000. For a family claiming for two children, the statutory annual entitlement is £27.05 × 52 (eldest) + £17.90 × 52 (second) = £2,337.40. If the higher earner reaches a gross ANI of £70,000, they sit exactly halfway through the taper window, triggering a 50% clawback charge equal to a £1,168.70 tax bill.
Historically, paying back the HICBC was a highly bureaucratic process, forcing hundreds of thousands of standard PAYE employees to register for and file an annual Self Assessment tax return solely to pay back their benefit cash.
To streamline this system, HMRC operates a digital collection alternative that is fully active for the current cycle. If you are a standard employed individual whose income crosses the threshold, you can opt to pay the charge directly through adjustments to your PAYE tax code using the HMRC digital portal. By decreasing your personal allowance code parameters dynamically, your company's payroll department automatically subtracts the required HICBC tax liability across your standard monthly pay packets, completely removing the legal obligation to complete an end-of-year self-assessment return — provided you have no other non-PAYE revenue streams. The summary card highlights when you sit inside this eligibility band.
If your individual salary comfortably exceeds the upper limit, it can be tempting to ignore the Child Benefit framework entirely to bypass the admin. Financial planners warn, however, that failing to complete the form can permanently damage your future State Pension entitlement.
Submitting a Child Benefit application secures vital National Insurance credits for the parent who stays at home or works reduced hours to care for a child under the age of 12. These credits count directly toward the 35 qualifying years required to claim the full UK State Pension. To protect these credits without getting trapped in a cycle of receiving cash only to pay it back at tax time, parents can tick the “no payments” box on the statutory form to opt out of physical cash payments while keeping the claim itself open and the NI credits flowing.
HMRC calculates HICBC liability against your Adjusted Net Income, not your top-line gross. ANI is computed after subtracting gross workplace pension contributions (salary sacrifice or net pay) and grossed-up Gift Aid donations — which makes pension sacrifice the single most powerful HICBC mitigation lever available to working parents. The slider in Block 03 above annualises a monthly sacrifice figure and feeds the result straight into the ANI line; drag it upward until the “Net benefit retained” figure on the summary card hits the full annual entitlement to see exactly how much you need to route through your pension to wipe out the charge.
The bonus: every pound you route through salary sacrifice also lands inside your pension pot free of Income Tax and Class 1 NI — the HICBC saving is layered on top of the standard tax-efficient pension build-up.

Compliance walkthrough of the 2026/27 HICBC: individual income basis (the household-reform was scrapped), the £60k–£80k taper at 1% per £200, and how to skip Self Assessment by paying the charge through your PAYE tax code.
The Adjusted Net Income loophole that lets you escape the HICBC entirely. How routing £4,000/yr through salary sacrifice can wipe a £467 charge off a £64,000 earner — and double-dip as a tax- and NI-free pension build-up.
Three pipes that all deposit into the same pension. Only one saves you NI; only one gives higher-rate relief automatically.
Every £1 between £100k and £125,140 costs 62p in tax + NI because Personal Allowance tapers away. The escape is salary sacrifice — and the math is generous.
