To avoid the High Income Child Benefit Charge, you either bring your adjusted net income below £60,000 through pension contributions or Gift Aid donations, or you opt out of receiving Child Benefit payments while keeping the claim itself active. Which route makes sense depends on how far above the threshold your income sits and whether you have room to shift money into a pension.
What Actually Triggers the Charge
The charge applies when the highest earner in a household has an adjusted net income above £60,000. Between £60,000 and £80,000 it tapers; at £80,000 or above, 100% of the Child Benefit received is clawed back through Self Assessment.1GOV.UK. The High Income Child Benefit Charge Threshold For every £200 of adjusted net income above £60,000, you owe 1% of the household’s Child Benefit for that tax year.
Two features of that formula matter for planning. First, the figure is adjusted net income, not gross salary. Adjusted net income starts with your total taxable income and then subtracts certain reliefs, including grossed-up Gift Aid donations and pension contributions.2HM Revenue & Customs. Personal Allowances: Adjusted Net Income Someone on £65,000 who pays enough into a pension can drop below £60,000 and owe nothing. Second, only the higher earner is liable, and it does not matter which partner receives the Child Benefit payments.3GOV.UK. Child Benefit Tax Calculator Marriage, civil partnership, and cohabiting are all treated the same way.
There is no pro-rata calculation if your income only crosses the threshold late in the year because of a bonus or a raise. If your full-year adjusted net income lands above £60,000, the charge applies to all Child Benefit received during that year.4GOV.UK. High Income Child Benefit Charge
Reducing Your Adjusted Net Income With Pension Contributions
Pension contributions are the most flexible lever. If you pay into a personal pension where the provider adds basic-rate tax relief, every £1 you contribute reduces your adjusted net income by £1.25. If you contribute gross, the full amount is deducted.2HM Revenue & Customs. Personal Allowances: Adjusted Net Income A gross pension contribution of £5,000 takes someone earning £65,000 down to £60,000 and eliminates the charge entirely.
Salary sacrifice is simpler still. Money sacrificed into a workplace pension never counts as employment income in the first place, so your P60 already reflects the lower figure and no further adjustment is needed. For people whose income sits in the £60,000 to £80,000 taper band, this is usually where the biggest saving comes from, because a modest increase in monthly pension contributions can cancel the charge outright while also boosting retirement savings.
Reducing It With Gift Aid Donations
Charitable donations made through Gift Aid are grossed up and then deducted from your net income. A £1,000 Gift Aid donation grosses up to £1,250, and the full £1,250 comes off your adjusted net income.2HM Revenue & Customs. Personal Allowances: Adjusted Net Income Few people give money away purely to escape the charge, but if you already donate, making sure those donations run through Gift Aid rather than as untagged transfers has a direct effect on what you owe.
Opting Out of the Payments Instead
If your income clearly sits at £80,000 or above and pension planning is not going to close the gap, you can stop the Child Benefit payments themselves. Opting out through the Child Benefit online service, by phone, or by post to the Child Benefit Office stops the payments, and because no benefit is received, no charge is due and you do not need to file a Self Assessment return solely for HICBC.5GOV.UK. High Income Child Benefit Charge – Opt Out of Child Benefit Payments
Keep the underlying claim open. Staying registered for Child Benefit does two things that matter. The claimant (typically the lower-earning parent) continues to receive National Insurance credits that count toward their State Pension, and your child automatically gets a National Insurance number before turning 16 without having to apply separately.5GOV.UK. High Income Child Benefit Charge – Opt Out of Child Benefit Payments Those NI credits are especially valuable for a parent who is not working or is working part-time, because gaps in contributions can permanently reduce the State Pension.
If your income later drops below £60,000, you can restart payments by contacting the Child Benefit Office, and HMRC will confirm whether any backdated payments apply.6GOV.UK. High Income Child Benefit Charge – Restart Your Child Benefit Payments Opting out is a switch, not a one-way door.
Why Opting Out Isn’t Always the Right Answer
From April 2026, Child Benefit pays £27.05 per week for the eldest or only child and £17.90 per week for each additional child.7GOV.UK. Child Benefit, Guardian’s Allowance and Tax Credits Over a full year, that is roughly £1,407 for one child or £2,338 for two.
For a household with two children and a higher earner on £70,000, the charge is 50% of the benefit received, or about £1,169 for the year. The other £1,169 stays with the family. Stopping payments the moment income clears £60,000 is a common instinct and often the wrong one, particularly when you sit in the lower half of the taper. Run the calculation before you switch payments off.
If You Do Owe the Charge, File Through Self Assessment
The charge is settled through Self Assessment. If you were not already in the system, register with HMRC by 5 October following the end of the tax year the charge applies to. For a charge arising in 2025/26, that means registering by 5 October 2026.8GOV.UK. High Income Child Benefit Charge – Pay the Tax Charge Through Self Assessment
You will need a Government Gateway user ID, a Unique Taxpayer Reference, your P60, and any P11D forms showing benefits like a company car or private health insurance.9GOV.UK. Your P45, P60 and P11D Form Records of pension contributions and Gift Aid donations matter too, because these directly affect your adjusted net income. The return has a specific Child Benefit section where you enter the total received in the tax year. Online returns and payment are due by 31 January following the end of the tax year.10GOV.UK.

What Happens If You Ignore It
Missing the filing deadline triggers an automatic £100 penalty, with daily penalties of £10 kicking in after three months up to a maximum of £900, and further percentage-based penalties at six and twelve months.11GOV.UK. Self Assessment Tax Returns: Penalties
A separate and often larger penalty applies if you fail to tell HMRC you are liable at all. This “failure to notify” penalty is calculated as a percentage of the unpaid tax: 0% to 30% for a non-deliberate failure disclosed within 12 months, up to 70% for deliberate failures, and up to 100% for deliberate concealment.12HM Revenue & Customs. Compliance Checks – Penalties for Failure to Notify – CC/FS11 Coming forward before HMRC contacts you significantly reduces the range. Interest on overdue income tax currently runs at 7.75%.13GOV.UK.

Watch for Changes in Your Household
Moving in with a new partner can make you liable for the charge even though the children are not yours and the payments go to someone else. HMRC assesses unmarried couples on a week-by-week basis, and from the week you move in, your income counts. If you become the highest earner in the household and your adjusted net income is above £60,000, the charge falls on you for Child Benefit received from that point.
This is where people most commonly get caught out, because the person who owes the tax may not know Child Benefit is being claimed in the household at all. If you move in with a partner who has children, have a direct conversation about whether they claim Child Benefit and what your combined income looks like. Separation works in the opposite direction: once you stop living together, the charge only applies to the weeks of the tax year you shared a household.
