High Income Child Benefit Charge (HICBC) Calculator

Updated for the 2026/27 tax year
Work out how much of your Child Benefit you'll repay through the High Income Child Benefit Charge in 2026/27. Unlike calculators that look at the charge alone, this figure is calculated as part of your whole tax position — so it reflects how pension contributions, Gift Aid and your adjusted net income actually interact to raise or lower what you owe, not the charge in isolation.

How the charge is worked out

The High Income Child Benefit Charge claws back Child Benefit once the higher earner in a household has an adjusted net income above £60,000. It is charged on the higher earner's income individually — not on household income — so two partners each earning £55,000 pay nothing, while a single earner on £75,000 pays a substantial charge.

Between £60,000 and £80,000 the charge tapers: you repay 1% of your Child Benefit for every £200 of income over £60,000. At £80,000 the taper reaches 100% and the entire benefit is clawed back. Below £60,000 there is no charge; above £80,000 the charge equals the full Child Benefit you received.

Pension contributions and Gift Aid reduce the charge — the bit most tools miss

Because the charge is based on adjusted net income, not gross salary, you can reduce or even eliminate it. Two reliefs lower adjusted net income directly:

In the £60,000–£80,000 taper, this cuts the charge pound-for-pound — and contributing enough to get back under £60,000 removes it entirely. The calculator above shows exactly how much a pension contribution or Gift Aid donation saves you, because it models the interaction between your income, these reliefs and the charge in one place. That's the angle almost no dedicated HICBC calculator handles.

MyTaxReality runs the charge through the same engine that knows your Income Tax, Personal Allowance taper and pension — so the figure reflects your real position, and the reliefs that change it, rather than the charge on its own.

Paying the charge from 2026

Historically the only way to pay the High Income Child Benefit Charge was to register for Self Assessment. From 2026, employed taxpayers can instead have the charge collected through their PAYE tax code, without a Self Assessment return. The amount owed is exactly the same — this is a change to how it's collected, not how much you pay.

The charge is only one part of your position — pensions and Gift Aid ripple through the rest of it too.
