Section 6: Territorial scope of charge to tax
45.This section sets out the territorial limits of the charge on trade profits. It is based on section 18(1)(a)(i) and (ii) of ICTA.
46.Trades within Schedule D Case I are those “carried on in the United Kingdom or elsewhere”. That expression appears wide enough to include trades carried on wholly abroad. But Colquhoun v Brooks (1889), 2 TC 490 HL explained that the charge under Schedule D Case I covers only trades carried on at least partly in the United Kingdom. Trades carried on wholly abroad are within Schedule D Case V.
47.The distinction between Schedule D Cases I and V is important because only a person who is resident in the United Kingdom is chargeable on trade profits under both Cases. A person who is not resident in the United Kingdom is chargeable on trade profits only under Schedule D Case I. The abbreviated descriptions “UK resident” and “non-UK resident” are defined in section 878(1) of this Act.
48.Subsection (1) sets out the position for a person resident in the United Kingdom: the charge to tax covers all trade profits, wherever the trade is carried on.
49.Subsection (2) sets out the position for a person not resident in the United Kingdom: the charge to tax is restricted to profits from a trade carried on at least partly in the United Kingdom. In the case of a trade carried on partly in the United Kingdom, the charge is further restricted to the profits from the part of the trade carried on in the United Kingdom.
