Section 17: Effect of becoming or ceasing to be a UK resident
106.This section deals with the consequence of an individual trader moving to or from the United Kingdom. It is based on section 110A of ICTA.
107.Subsection (1) sets out the circumstances in which the section applies. In accordance with section 6 of this Act a non-resident individual who carries on a trade at least partly outside the United Kingdom is charged to tax only on the profits of any part of the trade carried on in the United Kingdom. Without this section it would be possible for a taxpayer to be charged to tax on profits which accrue in part of a basis period when the taxpayer is not resident in the United Kingdom.
108.If the trade is carried on in partnership and one of the partners changes residence, the rule in this section does not apply. But there is a special rule that applies only to the partner. See sections 852(6) and 854(5) of this Act.
109.Subsection (2) sets out the consequences of a change of residence. The trade is treated as ceasing and, if appropriate, a new one is treated as starting. There is no explicit rule in section 110A of ICTA to say when the trade is treated as ceasing or starting. The only sensible inference is that it is the date of the change of residence. The section makes this clear.
110.Subsection (3) ensures that losses are still available to be carried forward.
