How to claim Child Benefit

This advice applies to Scotland. See advice for See advice for England, See advice for Northern Ireland, See advice for Wales

You can claim Child Benefit at any time, but it's best to do it as soon as your child is born or comes to live with you.

If you've just had a baby you need to register the birth before you claim.

Your Child Benefit will be backdated to when the child was born - up to a maximum of 3 months - so you won't miss out on payments.

Get your personal information ready

You'll need the following personal details and documents:

  • your and your partner's National Insurance (NI) number - if you don't have one you can apply for an NI number on GOV.UK

  • your average annual income before tax

  • your bank, building society or Post Office account details

  • your child's birth certificate or adoption certificate - if you've lost their certificate, you can order a copy

  • your other children's Child Benefit numbers if you're claiming for an additional child - these will be on your benefit letters from HMRC

  • your child's passport - if your child was born outside the UK

Claiming Child Benefit

You can make a claim for Child Benefit online on GOV.UK.

You can also make a claim using the HMRC app:

You can make a claim for someone else in some circumstances - for example if they're severely disabled.

If you can’t make a claim online or using the app, you’ll need to download and fill out the claim form on GOV.UK. Post the form to HM Revenue and Customs (HMRC) with your documents. When you send your claim form, certificates or passport, ask the post office for proof of postage - you might need to prove when you sent them.

HMRC might contact you if they need more information about your claim. For example, if you don't live with the child they might ask you for evidence that you pay to support them.

Getting paid

If you apply for Child Benefit online or using the app, you could get your first payment within 3 days.

If you apply by post, it could be 3 months until you get your first payment.

If you were eligible for Child Benefit before HMRC got your claim, it will be automatically backdated - up to a maximum of 3 months. This means you'll get an extra 1, 2 or 3 months' of Child Benefit included in your first payment.

Child Benefit will be paid into your bank account every 4 weeks.

You can ask to be paid weekly on the claim form if you're a single parent or if you or your partner gets either:

  • Income Support

  • income-based Jobseeker's Allowance

  • income-based Employment and Support Allowance

  • Universal Credit

  • Pension Credit

If you don't have a bank account

To get paid, you'll need to open a bank, building society or post office account.

If you've tried to open an account but your application was refused, you should get help from your nearest Citizens Advice.

What happens next

You can keep getting Child Benefit until the 31 August after your child becomes 16 - or until they turn 20 if they stay in education or training.

When your child turns 16, HMRC will send you a letter asking whether your child will stay in education or training. You must reply to this letter to keep getting Child Benefit.

If your family circumstances change, you should report it to HMRC - for example, if your child moves out or you separate from your partner.

If you or your partner earns over £60,000 a year you might have to pay more tax. This would only start from the April after you claim. You can find out more about the tax charge and how you pay it on GOV.UK.

If your claim is refused and you disagree with HMRC's decision, you can ask them to think again - this is called 'mandatory reconsideration'.
