Self Assessment guides by trade
What you can claim depends on what you do. A plumber and a Vinted seller fill in the same tax return, but almost none of the same figures. These guides set out the allowable expenses for one trade at a time, the HMRC forms that go with it, and the rule that catches people out most often.
All figures are for the 2025-26 tax year. The online filing deadline is 31 January 2027.
