Submit evidence to support your Child Benefit application
Use the online form to send evidence to support your Child Benefit application, if you've been asked for it by HMRC.
If you’ve applied for Child Benefit, you might get a letter asking you to give evidence to show that you’re eligible.
The letter will tell you what evidence you need to send. It might also include a form for you to complete.
When to send evidence
You need to send evidence within 14 days of getting the letter asking for it.
For example, if you got the letter on 12 February, you’d need to submit your evidence on or before 25 February.
If you do not send evidence within 14 days, we’ll make a decision based on the information we already have.
Who can send evidence
Only the person who applied for Child Benefit can send evidence.
Before you start
You’ll need:
- your National Insurance number
- a digital copy of the evidence we asked for
- a photo or scan of the completed form, if we sent you one
Send evidence online
You’ll need to sign in to send evidence. If you do not have sign in details, you’ll be able to create them.
What happens next
We’ll send you a letter within 15 working days, telling you whether you’re eligible. We might also ask you to send original versions of the evidence.
If you’re not eligible, we’ll explain how you can challenge the decision.
