In short

  • Costs you had to pay to do your job and were not repaid for, where HMRC agrees the category.
  • The big five: mileage, uniform laundering, tools, professional fees, working from home.
  • Plus subsistence, specialist clothing and, rarely, training.
  • Not: commuting, ordinary clothes, DBS checks or an ordinary driving licence, food at your normal workplace. Some licence fees do count, such as the SIA licence and LGV or PCV licence renewals.
