Report a change of circumstances online for Child Benefit or Guardian's Allowance

You can report a number of changes online that may affect your Child Benefit. You need to report each change separately.

Make sure you use the correct form below for the specific changes you want to report. If there isn't a specific form for your change, you can use the general enquiry form in the section below 'Reporting other changes of circumstances'.

Information to get together before you start

You won't be able to save any information that you type into the online form, so have the following information handy:

  • the date of the change and any relevant facts you want to report
  • your full name
  • your email address
  • your full postal address including postcode
  • your date of birth
  • your National Insurance number
  • the full name and date of birth of any children you receive Child Benefit for

This is important as it helps the Child Benefit Office to confirm your identity. They have a duty of care to protect you and will not reply where they think that confidentiality may be breached. If you don't have your National Insurance number, you can still send in an online query.

Security of your information

By emailing from the HM Revenue & Customs website your email is more secure. But the reply won't be so it will not include confidential information. The Child Benefit Office will email you if necessary to explain that they will be replying fully by letter or phone.
