You can authorise a tax adviser (for example, an accountant) to act
on your behalf to deal with any issues with your High Income Child Benefit Charge.
After they’re authorised, they’ll be able to contact the Child Benefit Office:
- about any Child Benefit payments you’ve had
- if you decide to stop or restart your Child Benefit payments
- to discuss issues relating to your Child Benefit for you
The person who claimed Child Benefit must fill in the form.
You must tell the Child Benefit Office immediately if you want to remove or change your nominated tax adviser and cancel this authorisation.
Use the online form service (sign-in to, or set up a Government Gateway account)
Once you’ve used the online form service you’ll also need to fill in and send a form 64-8 if you haven’t already, send the form 64-8 to us by post.
You’ll be given a reference number when you submit the online form. Include this number with the form 64-8 you send by post to the address below.
You can track the progress of the form online using the same reference number.
Fill in the form on-screen then print and post it to the Child Benefit Office
Instead of applying online, you can fill in the form on screen, print it off and send it to us along with the form 64-8 if you haven’t sent us one already.
If you submit the form this way, you can’t track its progress online.
Send your form and 64-8 to:
Child Benefit Office
PO Box 1
NEWCASTLE UPON TYNE
You’ll need to fully fill in the form before you can print it off. You can’t save a partly completed form so have all your information with you before you start to fill it in.
- your National Insurance number (you’ll find this on your payslip, P60 and tax return)
- your Child Benefit number (you’ll find this on your Child Benefit award notice and on any letters sent by the Child Benefit Office)
- your child’s first name, last name and date of birth
- your tax adviser’s name or business name, and address
If you can’t use the online service or fill in the form on screen you can print it off, fill it in by hand and post it to the address above.

If you’re using a mobile device, for example, a smart phone, an iPad or other tablet, make sure you’re set up to print from your device before you start.
