Child Benefit Rules and Guide

Being responsible for one or more children means you could qualify to claim Child Benefit. In some cases, you do not need to be the actual parent to receive Child Benefit support. This overview section answers the common questions about Child Benefit rules in United Kingdom. Discover how to get and manage CHB, the eligibility criteria, and the current rates.


There are several reasons to sign up, even if you decide not to get the payments – due to a ‘high income’. Using the Child Benefit tax calculator will help you make the decision.

You will find current information on Child Benefit rates and how to check your next family allowance payments.

For example, claimants want to know:

What happens with payments if the due dates fall on UK bank holidays or during festive seasons (e.g. Christmas and Easter)?

This category overview also explains how to find out your Child Benefit Number (CHB) and how you can make a complaint. Check what happens when children are in hospital or your Child Benefit stops without notice.

Use the Child Benefit online services telephone contact number during their weekly opening hours. You can use HMRC Child Benefit Office mailing address if you prefer to send your enquiry by post.

So, let’s take a closer look:

As you might expect, this is quite a big section. So, to make things simple we have divided the information you need into three main categories:

  1. Advice and information about claiming Child Benefit as a parent or on behalf of someone else.
  2. A section explaining how the payments work and the tax implications for high earners.
  3. Key information on managing your Child Benefit including when it stops and how to report changes.

Child Benefit Number

There may be situations when you need to know how to find your HMRC Child Benefit Number UK. As a rule, the number (aka proof of qualification) proves you qualify.

Proving You Qualify

You cannot get written proof of Child Benefit at their office. But other methods include your Child Benefit award notice, the latest tax credits award notice, or a Child Benefit entitlement letter from HMRC in your Personal Tax Account.

Often, the Child Benefit number on bank statement will suffice. The number starts with ‘CHB’ followed by eight (8) numbers and 2 letters (e.g. CHB12345678 AB).

Note: Having a baby can result in a search for financial support. The Childcare and Parenting section covers all the topics about motherhood that matter the most, including childcare and schooling.
