Commentary on Sections Glossary Part 2: Employment income: charge to tax Section 40: Duties on board vessel or aircraft
165.This section sets out the rules for deciding where duties should be treated as being performed if they take place on a vessel or an aircraft. It derives from section 132(4)(b) of ICTA. Subsections (3) to (6) set out the rule for the treatment of seafarers carrying out duties on a ship. This derives from paragraph 5 of Schedule 12 to ICTA.
166.“Ship” takes its everyday meaning, subject to the exception in respect of an “offshore installation” as provided by the Mineral Workings (Offshore Installations) Act 1971. Further guidance on the meaning of those terms is given in the Inland Revenue Schedule E manual at paragraphs SE 33221 to 33222.
