Via Revenue & Customs Brief 11 (2022) HMRC now accepts that face masks should properly be considered to be items of clothing.
This means that face masks designed and marketed as suitable for young children (under the age of 14) qualify for zero rating.(VAT Act 1994 Schedule 8 Group 16).
VAT Notice 714 – Young children’s clothing and footwear has been updated.
Businesses which have been treating these sales as standard rated will be due a refund, subject to the unjust enrichment rules.
