Parents of teens reminded to extend Child Benefit claim online 16 May 2025Parents of 16 to 19-year-olds will receive reminders from HMRC to extend their Child Benefit claim by 31 August if their child is staying in education or training or payments will automatically stop. Child Benefit will automatically stop on 31 August on or after a child's 16th birthday if it's not extended. Between May and July, letters will be sent to parents reminding them to go online to confirm if their teenager is staying in full time education or approved training after they finish their GCSEs to continue receiving their Child Benefit. Parents can extend their claim via the HMRC app or online on GOV.UK. The letters also contain a QR code which takes parents straight to the digital service on GOV.UK. Child Benefit is currently worth £26.05 per week - or £1,354.60 a year - for the eldest or only child and £17.25 per week - or £897 a year - for each additional child. Myrtle Lloyd, HMRC's Director General for Customer Services, said: 'Child Benefit is an important boost to families. As soon as you know what your teenager is planning to do, extend your claim in minutes to guarantee your payments continue in September. Simply go to GOV.UK or the HMRC app to confirm today.'
