What Is Child Benefit?

Child Benefit is one of the most familiar parts of the UK benefits system, paid to millions of families to help with the cost of raising children. Yet it has a few twists that catch people out, from a tax charge for higher earners to a quiet but important link with your State Pension. Understanding how it works, and why it is usually worth claiming even when you might have to pay some back, can make a real difference to your family's finances. This guide explains it all. This is general information, not financial or legal advice.

What it is

Child Benefit is a regular, tax-free payment from HM Revenue and Customs (HMRC) to people responsible for bringing up a child under 16, or under 20 if the child stays in approved education or training. It is paid to help with the costs of raising a child, and unlike many benefits it is not means-tested in the usual sense: most people responsible for a child can claim it, regardless of their savings.

Only one person can claim Child Benefit for a particular child. For couples, it usually makes sense for the claim to be in the name of the parent who is not working or earns less, for reasons explained below. Payments are normally made every four weeks, into a single bank account.

There is one important wrinkle for higher earners, the High Income Child Benefit Charge, which we come to shortly. But even where that applies, claiming can still be worthwhile.

Child Benefit is about more than the cash. Quietly, it protects the claimant's State Pension and registers a child for their National Insurance number, which is why even high earners are often advised to claim.

How much it pays

Child Benefit is paid at two rates:

• A higher weekly rate for your eldest or only child.
• A lower weekly rate for each additional child.

The exact figures are set by the government and reviewed periodically, so it is best to check the current amounts on GOV.UK rather than relying on a number that may have changed. There is no limit on the number of children you can claim for, and the payment continues as long as the eligibility conditions are met.

Who can claim

To claim Child Benefit you generally need to:

• Be responsible for a child under 16, or under 20 if they remain in approved education or training (such as A levels or certain apprenticeships, though not most university courses).
• Live in the UK and meet residence rules.

You do not have to be the child's parent to claim; what matters is that you are responsible for them, for example if you are a guardian or foster carer in certain circumstances. If two people could claim for the same child, only one can actually receive it, and there are rules to decide who has priority if there is a dispute.

The High Income Child Benefit Charge

This is the part that surprises people most. The High Income Child Benefit Charge (HICBC) is a tax charge that can claw back some or all of your Child Benefit if you, or your partner, have an individual income above a set threshold.

Two points are essential to understand:

1. It is based on individual income, not household income. This can produce results that feel unfair: a couple each earning just under the threshold keeps the full benefit, while a single earner over it may lose some or all of theirs.
2. It is tapered. Between the lower and upper income limits, the charge gradually increases, reclaiming a rising proportion of the benefit. Above the upper limit, the charge effectively cancels out the entire payment.

The charge is collected through Self Assessment, so if it applies to you, the higher earner usually has to register and file a tax return to pay it. Because this is a tax matter rather than a benefits one, our separate explainer on the High Income Child Benefit Charge goes into the detail, and you may also find our overview of PAYE useful for understanding how income is assessed.

Why claim even if you opt out of payments

Here is the advice that saves people from a costly mistake. If your income means the charge would wipe out the benefit, you might be tempted not to claim at all. There is a better option: claim, but choose not to receive the payments.

Doing this keeps two valuable, non-cash benefits:

• National Insurance credits. A parent who claims Child Benefit for a child under 12, and who is not in paid work or earns too little to pay National Insurance, receives NI credits that count towards their State Pension. Failing to claim can leave gaps in their record that reduce their pension years later.
• A National Insurance number for your child. When the child turns 16, they are issued an NI number automatically, without having to apply.

This is why the claim is often best made in the name of the parent who is not working, even in a high-earning household: it protects their State Pension. You can later opt back in to receiving payments if your circumstances change.

How to claim

You can claim Child Benefit as soon as you have registered the birth or a child comes to live with you. Apply through GOV.UK, where you can complete the claim online or download a form. You will need details such as the child's birth certificate and your bank and National Insurance information.

It is worth claiming promptly, because Child Benefit can only be backdated by up to three months. If you are unsure how the charge affects you, or whether to receive payments, free help is available from MoneyHelper and Citizens Advice, and HMRC's own guidance explains the current rates and rules. Families on a low income or with childcare costs should also check related support such as Tax-Free Childcare.

The bottom line

Child Benefit is a regular, tax-free payment for people responsible for a child under 16, or under 20 in approved education, with a higher rate for the eldest child and a lower rate for each other child. The High Income Child Benefit Charge can claw it back for higher earners, based on individual rather than household income, and is collected through Self Assessment. Crucially, even if the charge applies, it is usually worth claiming and opting out of payments, to protect the claiming parent's State Pension and secure a National Insurance number for the child. Claim promptly, check the current rates on GOV.UK, and get free advice if the charge leaves you unsure what to do.
