Child Benefit - How do I claim Child Benefit?

You should claim Child Benefit as soon as you have registered the birth of your child or if a child comes to live with you.

You can apply for Child Benefit online or download a claim form or phone the Child Benefit Office for a claim form:

Telephone: 0300 200 3100
Textphone: 0300 200 3103
Welsh Language: 0300 200 1900

Use the Relay UK service if you can’t hear on the phone - dial 18001 then 0300 200 3100.

What documents will I need to claim Child Benefit?

You must give evidence of your child, for example, a birth or adoption certificate. You should also give your national insurance number . If you do not have a national insurance number , send in the claim form anyway to save delays. You may also be asked for proof of your identity such as a birth certificate, passport or driving licence.

When will my Child Benefit claim begin?

Child Benefit can be backdated for up to three months if you would have been entitled to it earlier. It does not matter why your claim is late. Request this when claiming.

Change of circumstances

You must report changes in your circumstances which might affect your entitlement to this benefit.

When your child turns 16, you should tell HMRC if your child stays in or leaves approved education. You can report online.

You can also use the HMRC app to manage your Child Benefit claim online.
