HM Revenue and Customs has issued a formal warning to parents of teenagers across the United Kingdom that Child Benefit payments worth up to £1,406.60 per year will cease automatically from 1 September unless eligible households extend their claims before the 31 August deadline. The instruction applies specifically to parents of 16 to 19-year-olds whose children are continuing into full-time education or approved unpaid training following their GCSEs or Scottish National 5 qualifications.
What Is at Stake
Child Benefit currently pays £27.05 per week for the eldest or only child, amounting to £1,406.60 annually, with an additional £17.90 per week — or £930.80 per year — payable for each subsequent child. There is no statutory cap on the number of children for whom a household may claim, subject to the broader Benefit Cap, making the payment a meaningful source of financial support for larger families in particular.
HMRC despatched approximately 1.5 million reminder letters to affected households earlier this year and opened its digital extension service on 1 April, giving parents ample opportunity to act in advance of the deadline. The letters include a QR code linking directly to the online portal. Despite this, the department has now issued a further reminder via its official X account, urging parents not to miss out.
Who Must Act and How
Parents are required to extend their claim only if their teenager is commencing a new course or qualifying training in September. Those whose children are already partway through a programme previously notified to HMRC need take no further action. The extension can be completed either through the HMRC app or via the GOV.UK website, and HMRC reports that more than half of the 874,000 parents who extended claims last year did so through one of these digital channels.
Qualifying education for the purposes of an extension is defined as full-time study in non-advanced education; approved training must be unpaid. Part-time courses and advanced qualifications — such as a first degree — do not qualify. Parents who fail to act before the 31 August cut-off will see payments halt immediately, with no further disbursements from 1 September onwards.
High Income Considerations
Households in which either the claimant or their partner earns between £60,000 and £80,000 should note that the High Income Child Benefit Charge applies. Under rules effective for the 2026/27 tax year, one per cent of the benefit must be repaid for every £200 of income above the £60,000 threshold. Where individual income reaches or exceeds £80,000, the entirety of Child Benefit received must be repaid to HMRC.
Myrtle Lloyd, HMRC’s Chief Customer Officer, has previously emphasised the straightforward nature of the process: “You can extend your Child Benefit claim today in minutes via the HMRC app or online at GOV.UK,” she noted, urging parents not to wait for a reminder letter if their teenager’s plans are already confirmed. The message is clear — the administrative burden is minimal, and the financial consequence of inaction is not.
