An employee whose salary crosses £60,000 gets a letter. Their tax code changes, HMRC writes to them about the High Income Child Benefit Charge, and the payroll deals with it.
A freelancer whose profit crosses £60,000 gets nothing at all. There is no coding notice, no trigger, and no point in the year at which anybody tells you. The charge simply appears in the tax calculation when the return is prepared, months after the money it relates to has been spent.
What the charge actually is
The High Income Child Benefit Charge is an income tax charge on the higher-earning partner in a household that receives child benefit, where that partner's adjusted net income exceeds £60,000. It claws the benefit back gradually:
- Below £60,000 — no charge.
- Between £60,000 and £80,000 — 1% of the child benefit received for every £200 of income above £60,000.
- At £80,000 and above — the charge equals the full amount of child benefit received.
For 2026/27 the child benefit rates are £27.05 a week for the eldest or only child, which is £1,406.60 a year, and £17.90 a week for each additional child, which is £930.80 a year. Two children is therefore £2,337.40 a year at stake, and three children is £3,268.20.
Adjusted net income is not your profit
This is where most of the useful decisions live. Adjusted net income is your total taxable income from every source — trading profit, employment, rental, savings, dividends — less certain reliefs, of which two matter to almost everyone:
- Gross personal pension contributions. A payment into a personal pension or SIPP is grossed up by basic rate relief, and the grossed-up figure comes off adjusted net income.
- Gift Aid donations, grossed up. A £80 donation is £100 of gross giving and reduces adjusted net income by £100.
Trading losses relieved against total income reduce it too. What does not reduce it is the money you left in the business, because sole traders and partners are taxed on profit rather than on drawings. A good year on paper produces the charge even when the cash went straight back into equipment.
Worked example: the freelancer at £68,000
Illustrative figures. A freelance designer has a trading profit of £68,000 in 2026/27 and no other income. Their partner earns £24,000, so the charge falls on the designer as the higher earner. They have two children and receive child benefit of £2,337.40.
Adjusted net income: £68,000
Excess over £60,000: £8,000
£8,000 ÷ £200 = 40, so 40% of the child benefit is clawed back
40% × £2,337.40 = £934, payable through self assessment
Now look at the marginal rate inside the band. The whole £2,337.40 is withdrawn across £20,000 of income, which is 11.7p in every extra pound. On top of 40% income tax and 2% Class 4 National Insurance, this designer is losing 53.7% of every additional pound earned between £60,000 and £80,000. With three children the withdrawal is 16.3p in the pound and the marginal rate is 58.3% — higher than anything an additional rate taxpayer faces.
The move that pays for itself
Because pension contributions reduce adjusted net income, they work twice inside this band. Take the same designer and a personal pension contribution of £8,000 net:
Grossed up at basic rate: £10,000 lands in the pension
Adjusted net income falls to £58,000, so the charge drops from £934 to nil
The basic rate band extends by £10,000, moving £10,000 of profit from 40% to 20% — £2,000 claimed through the tax return
Net cost: £8,000 − £2,000 − £934 = £5,066 for £10,000 in the pension
That is 49.3% effective relief on the contribution. One honest caveat: pension contributions do not reduce Class 4 National Insurance, because relief is given at source and through the tax return rather than as a deduction from trading profit. The saving is income tax and the child benefit charge, not National Insurance.
Gift Aid works the same way on adjusted net income. Our guide to pensions for the self-employed covers the contribution limits and the annual allowance that sit around this.
Who pays it, and who claims it
The charge falls on whichever partner has the higher adjusted net income, whether or not that is the person who claims the child benefit. "Partner" is wider than spouse: it covers a civil partner and anyone you live with as though you were married or civil partners. Two people each earning £59,000 pay nothing. One person on £85,000 with a partner earning nothing loses the lot.
That produces a decision, and the wrong answer to it is common. If your income is comfortably above £80,000 and the whole benefit will be clawed back, you can opt out of receiving the payments while staying registered for child benefit. Do not simply never claim. Registering gives the parent at home National Insurance credits towards the state pension while a child is under 12, and the child is automatically issued a National Insurance number before they turn 16. Those are worth having, and they are free.
Paying it: the self-employed have fewer options
From 2025/26 employees have been able to pay the charge through PAYE without filing a return. That route is closed to you if you are already required to file for another reason, and self-employment is exactly such a reason. So for a sole trader the charge is assessed through the tax return and paid with the rest of the self assessment liability.
If the charge applies and you are not already registered for self assessment, you must notify HMRC by 5 October following the end of the tax year. Missing that is a failure to notify, and it carries its own penalty separate from anything due on the tax itself.
The problem with irregular income
The awkwardness for freelancers and contractors is that adjusted net income is not knowable until the year has ended, and by then the two levers that move it — pension contributions and Gift Aid — must already have been pulled. A contribution made on 6 April is a contribution in the wrong tax year.
The workable habit is two estimates a year. Around the end of September, take the profit to date, project the rest of the year, and see where adjusted net income is heading. Around the middle of February, do it again with nine or ten months of real figures, decide the pension contribution, and make it before 5 April. Our post on managing irregular income covers the wider cashflow version of the same discipline, and the self-employed tax calendar has the dates.
What to do this week
- Establish whether anybody in the household receives child benefit and, if so, who claims it. A surprising number of people are not sure.
- Work out which partner has the higher adjusted net income. That is the person the charge attaches to, regardless of who claims.
- Project your trading profit for 2026/27 and add every other source of taxable income to it.
- Subtract gross pension contributions already made this tax year and grossed-up Gift Aid donations. That number is your adjusted net income.
- If it lands between £60,000 and £80,000, calculate the pension contribution that would bring it to £60,000 and price it properly — the effective relief in this band is far higher than the headline rate.
- If it is above £80,000 and likely to stay there, decide whether to opt out of receiving the payments. Stay registered either way.
- If a charge arises for a year you have not yet reported and you are not in self assessment, register now rather than waiting for the 5 October deadline to pass.
If your income comes from more than one place, the calculation gets harder before it gets easier — our post on side income and the trading allowance covers the smaller end of the same question.
