Child Benefit will stop on the last day of August after your child’s 16th birthday, unless you tell the Child Benefit office that they’re staying in approved education or training.
If you have a Government Gateway account you can do this online (click on the change that applies to you and you’ll be taken to an online form) or by calling 0300 200 3100. Anyone can set up a Government Gateway account for free – this allows you to access lots of government services online.
You should get a letter or email from the Child Benefit office during the school year when your child turns 16. This will ask what they plan to do. If you don’t get the email or letter, contact Child Benefit.
