Details

Use form CH105 if you want an intermediary, such as Citizens Advice, to help you with your Child Benefit.

Do not use form CH105 to authorise a paid agent such as an accountant or other professional adviser to help you with your Child Benefit. You should use form 64-8 instead.

Email HMRC to ask for the form in Welsh.
