Families need to notify HMRC before 31 August if their 16 to 19-year-old children are staying in non-advanced approved education or training, or their Child Benefit payments will stop. This extension requirement ensures continued eligibility for families whose teenagers are not leaving education after age 16. The deadline applies to all parents receiving Child Benefit for young people in qualifying education or apprenticeships.
