Who pays the High Income Child Benefit Charge if my partner claims?
Who counts as my partner for the charge?
GOV.UK’s High Income Child Benefit Charge overview defines a partner as someone you are not permanently separated from and who you are married to, in a civil partnership with, or living with as if you were. The Low Incomes Tax Reform Group (LITRG) uses the same couple test. A boyfriend or girlfriend who lives elsewhere is not a partner for this charge. Two people who share a home as if they were married are treated as partners even if they have never married.

| Your situation | Partner for HICBC? | What that means |
|---|---|---|
| Married or in a civil partnership, still together | Yes | The higher earner’s adjusted net income is the one that matters |
| Living together as if married or in a civil partnership | Yes | Same test — the claim name does not move the charge |
| Permanently separated | No | GOV.UK’s wording takes that person out of the partner definition |
| Separated during the tax year | Ask HMRC in writing if you cannot agree the facts | HMRC replies yes or no on who had Child Benefit or the higher income; it does not share the other person’s figures |
GOV.UK also says the charge may apply if someone else gets Child Benefit for a child living with you and they contribute at least an equal amount towards the child’s upkeep. The child does not have to be your own child.
Does it matter who is named on the Child Benefit claim?
Not for who pays the tax. LITRG’s High income child benefit charge page states the charge is calculated on the adjusted net income of the higher-income partner, regardless of who claims or receives the benefit, the other partner’s income, or whose child the payments are for. The parent who claims still holds the Child Benefit award and the National Insurance credits that go with it. The higher earner is the person who may have to pay the charge to HMRC.
That split is why a P60 or an HMRC letter can land on the higher earner even though the Child Benefit payment goes into the other parent’s account. The payment and the tax are two different systems.
What if we both earn over the threshold?
GOV.UK says that if your adjusted net income is over the threshold and so is your partner’s, then whoever has the higher income is responsible for paying the tax charge. The live thresholds on that page, matching contracts/tax-year-2026-27.json, are: over £60,000 from tax year 2024 to 2025 onwards, with the charge reaching the full Child Benefit amount from £80,000. For tax years up to 2023 to 2024 the start point was £50,000 and the full clawback was £60,000.

| Higher earner’s adjusted net income | Other partner’s adjusted net income | Who pays |
|---|---|---|
| £59,000 | £40,000 | Neither — nobody is over the £60,000 start point used from 2024–25 |
| £72,000 | £25,000 | The £72,000 earner, even if they never touch the Child Benefit payment |
| £72,000 | £68,000 | The £72,000 earner — both are over the threshold, so the higher figure pays |
| £85,000 | £82,000 | The £85,000 earner — the charge can equal the full Child Benefit for the year |
How does the higher earner tell HMRC?
The person with the higher adjusted net income is the one who uses PAYE or Self Assessment. The parent who only receives the payment does not file the charge on the higher earner’s behalf.
- Work out each person’s adjusted net income Follow GOV.UK’s adjusted net income steps. The figure is not the same as a P60 salary. It includes savings interest, dividends and taxable benefits such as a company car, then takes off listed reliefs such as Gift Aid and certain pension contributions.
- Confirm who is the higher earner If only one of you is over the threshold, that person is in scope. If both of you are over it, GOV.UK assigns the charge to whoever has the higher income.
- Estimate the charge on the official calculator Use the Child Benefit tax calculator. You need the dates the claim started and, if relevant, when payments stopped or you opted out.
- Pay through PAYE or Self Assessment GOV.UK’s overview lists both routes. Self Assessment is required if you need a tax return for another reason, or if it is later than 31 January in the year after the tax year you need to pay for. Otherwise the higher earner may be able to pay through PAYE.
What if I cannot get figures from my partner or ex-partner?
GOV.UK’s Self Assessment and PAYE pages both say you can write to HMRC to ask whether your partner or ex-partner gets Child Benefit or has a higher income than you. HMRC replies yes or no. It does not give you their financial information or their National Insurance number.
You can only ask for that yes/no reply if you and your partner either live together, or separated within the tax year you want information for. The letter needs the tax year, your name, address, date of birth, National Insurance number, Unique Taxpayer Reference if you have one, your adjusted net income, and your partner or ex-partner’s name. Send it to Pay As You Earn and Self Assessment, HM Revenue and Customs, BX9 1AS — the address printed on those GOV.UK pages.
In shortIn short: the claim name does not decide who pays. GOV.UK looks at the higher earner’s adjusted net income in a couple who are married, in a civil partnership, or living together as if they were, and who are not permanently separated. Estimate on the official calculator, then the higher earner uses PAYE or Self Assessment.
Questions parents ask
- My partner claims Child Benefit. Do I still have to tell HMRC if I am the higher earner?
- Yes, if your adjusted net income is over the threshold used for that tax year. GOV.UK puts the charge on the higher earner, not on the parent named on the claim. The official calculator estimates the charge; PAYE or Self Assessment is how that person pays it.
- We live together but we are not married. Does the charge still look at both of us?
- Yes, if you live together as if you were married or in a civil partnership and you are not permanently separated. GOV.UK’s partner definition includes that living-together test.
- What if our adjusted net incomes look about the same?
- GOV.UK assigns the charge to whoever has the higher income once both of you are over the threshold. Work each figure from the official adjusted net income steps rather than from a single payslip. If you cannot agree the facts, HMRC’s yes/no letter route is on the PAYE and Self Assessment pages.
- Does opting out of payments move the charge onto my partner?
- No. Opting out stops the Child Benefit payment, so there is no charge on money that is not paid. The partner definition does not change. The claimant stays registered and keeps the National Insurance-credit side of Child Benefit, as GOV.UK sets out on the overview page.
