Who Can Claim Child Benefit

You can claim Child Benefit if you are responsible for a child under 16 (or under 20 in approved education or training) and you live in the United Kingdom. There is no income limit for eligibility — even if you earn above £80,000, you can and should claim. Only one person can claim for each child.

A qualifying child includes your biological child, adopted child, stepchild, or any child living with you in a family arrangement such as a grandchild or a child placed with you through kinship care. The child must normally live with you, or you must be contributing at least the Child Benefit rate towards their upkeep each week. Fostered children do not qualify, as local authorities provide separate foster care allowances (per gov.uk eligibility rules).

There is no limit on the number of children you can claim for. Unlike Universal Credit, which restricts the child element to two children born after April 2017, Child Benefit pays out for every qualifying child in your household at the rates shown in the table above.

When Child Benefit Stops

Child Benefit stops on 31 August after your child turns 16, unless they remain in approved full-time education or training. If they do, payments continue until they turn 20. The course must involve more than 12 hours per week of supervised study or course-related practical work.

Approved education and training includes:

• A-levels, AS-levels, Scottish Highers, and the International Baccalaureate
• T-levels, BTECs, and NVQs up to Level 3
• Traineeships and apprenticeships at any level
• Other non-advanced college courses

University degrees, HNDs, foundation degrees, and other higher education courses do not count. When your child starts university or permanently leaves approved education, you must notify HMRC and payments will stop. During summer breaks between approved courses, payments continue automatically provided the child has been accepted onto a qualifying course starting the following term (per gov.uk 16-19 guidance).

Reducing the High Income Child Benefit Charge

If you or your partner earns between £60,000 and £80,000, pension contributions are the most effective way to reduce or eliminate the HICBC. The charge is based on your adjusted net income, which falls when you make pension contributions — particularly through salary sacrifice, where you also save National Insurance.

For example, a parent earning £65,000 with one child receives £1,406.60 per year in Child Benefit (per gov.uk 2025/26 rates). At that income, the HICBC claws back 25% — around £352. By putting an extra £5,000 into their workplace pension through salary sacrifice, their adjusted net income drops to £60,000 and the HICBC falls to zero. They keep the full Child Benefit and gain £5,000 in their pension pot.

Gift Aid donations also reduce adjusted net income. The key calculation is simple: every £200 you reduce your income saves 1% of your total Child Benefit. Use HMRC's Child Benefit tax calculator to model different contribution levels against your own income.

Protecting Your State Pension

Claiming Child Benefit provides Class 3 National Insurance credits towards your State Pension. This matters most if you are not working, work part-time, or earn below the National Insurance threshold. You need 35 qualifying years of NI contributions for the full new State Pension of £230.25 per week (per gov.uk 2025/26 rates). Each missing year permanently reduces your weekly pension.

If your income is above £80,000 and you would repay 100% of Child Benefit through the HICBC, you should still claim. Tick the box on the claim form that says "I do not want to receive Child Benefit payments." You will receive the NI credits without triggering any repayment obligation. This is especially valuable for the lower-earning partner in a couple — if they have gaps in their NI record from career breaks, part-time work, or time spent caring for children, they should be the one who claims to collect the credits.

Check your NI record at gov.uk/check-national-insurance-record to see whether you have gaps that Child Benefit credits could fill.

How to Claim

Claim online at gov.uk/child-benefit — it takes around 20 minutes. You will need your National Insurance number, your bank or building society details for payment, and the child's birth or adoption certificate. If the birth certificate is not yet available, you can submit the claim and send it later.

Child Benefit can be backdated up to 3 months from the date of your claim, but no further. Any payments before that 3-month window are lost permanently. Claim as soon as you register the birth or the child comes to live with you.

Payments are made every 4 weeks, usually on a Monday or Tuesday, directly into your bank account. Single parents can request weekly payments instead. The first payment typically arrives within 12 weeks of your claim being processed. You can also claim by post using form CH2, available on gov.uk.

Guardian's Allowance

If you are bringing up a child whose parents have both died, you may qualify for Guardian's Allowance of £22.10 per week on top of your Child Benefit (per gov.uk 2025/26 rates). You can also qualify in some cases where one parent survives — for example, if the surviving parent is in prison, detained in hospital, or their whereabouts are unknown. Guardian's Allowance is tax-free. Full details and how to apply are at gov.uk/guardians-allowance.

Changes You Must Report

You must tell the Child Benefit Office if any of the following happen:

• Your child leaves approved education or training, or starts working 24 or more hours per week
• Your child goes to live with someone else
• You or your child change address
• Your relationship status changes — you separate, divorce, or begin living with a new partner
• You or your partner's individual income rises above £60,000
• You change your name or bank details
• A child dies

Report changes through your Personal Tax Account on gov.uk or by calling the Child Benefit helpline on 0300 200 3100.
