(1)References in this Chapter to a deduction being allowed to a company are to be read in accordance with this section (and references to a deduction being made are to be read in that light).
(2)If a deduction is allowed to a company, the deduction is made in calculating for corporation tax purposes the profits of a trade or property business carried on by the company.
This is subject to subsections (3) and (4).
(3)If the company is a company with investment business (as defined in section 1218), the amount of the deduction is treated as expenses of management of the company.
But this subsection does not apply if the company's business is a property business (in which case subsection (2) applies instead).
(4)If the company is a company in relation to which section 76 of ICTA (expenses of insurance companies) applies, the amount of the deduction is treated as expenses payable falling to be brought into account at Step 1 in subsection (7) of that section.
(5)So far as this Chapter provides for a deduction to be allowed, it has effect despite section 53 (no deduction for items of a capital nature in calculating trading profits), including that section as applied by section 210 to the calculation of profits of a property business.
