Register with HMRC and file Self Assessment (or Corporation Tax return)
Enforced by:
HMRC
Taxes Management Act 1970
Anyone trading — including production that has moved beyond genuine own-use into selling goods or services — must notify HMRC of chargeability to tax. A sole trader registers for Self Assessment and files an annual return; a company registers for Corporation Tax and files a Company Tax Return (CT600) instead. Purely subsistence production for the household's own consumption, with no sale or exchange, does not itself trigger this duty.
