There are no special rules for controlled foreign companies and
IRUs. The general controlled foreign companies rules will apply.
For more information about controlled foreign companies see
INTM200000 onwards.
If income from IRUs would form part of the chargeable profits
of a UK company, the income will form part of the chargeable
profits of a controlled foreign company that could be
apportioned.
The granting of an IRU is the leasing of a property or right and falls within the definition of investment business (INTM205070). The fact that the business, if carried on in the UK, would be taxed under Case I of Schedule D makes no difference. The controlled foreign company is still deemed to carry on an investment business outside the terms of the exempt activities test (INTM205010).
