1439.This section applies only to companies and deems a commencement or cessation of a UK property business to take place in particular circumstances. It is based on section 337 of ICTA.
1440.Section 337 of ICTA is primarily a corporation tax rule. It applies only to companies and originates from the introduction of corporation tax. However it can be relevant to income tax.
1441.That is because non-resident companies are within the charge to income tax in respect of United Kingdom trade profits (when the trade is not carried on through a United Kingdom permanent establishment) and UK property business income. Section 337 of ICTA applies in cases of either inward or outward company migration. Where that involves a continuing trade or UK property business there will be a change of taxing regime from income tax to corporation tax or vice versa.
1442.Section 362 says what happens when a company enters or leaves the income tax regime: then its UK property business income is calculated as though it had commenced or discontinued the business.
