9 Computation of income: application of income tax principles.U.K.
(1)M1 Except as otherwise provided by the Tax Acts, the amount of any income shall for purposes of corporation tax be computed in accordance with income tax principles, all questions as to the amounts which are or are not to be taken into account as income, or in computing income, or charged to tax as a person’s income, or as to the time when any such amount is to be treated as arising, being determined in accordance with income tax law and practice as if accounting periods were years of assessment.
(2)For the purposes of this section “income tax law” means, in relation to any accounting period, the law applying, for the year of assessment in which the period ends, to the charge on individuals of income tax, except that it does not include such of the enactments of the Income Tax Acts as make special provision for individuals in relation to matters referred to in subsection (1) above.
(3)Accordingly, for purposes of corporation tax, income shall be computed, and the assessment shall be made, under the like Schedules and Cases as apply for purposes of income tax, and in accordance with the provisions applicable to those Schedules and Cases, but (subject to the provisions of the Corporation Tax Acts) the amounts so computed for the several sources of income, if more than one, together with any amount to be included in respect of chargeable gains, shall be aggregated to arrive at the total profits.
(4)Without prejudice to the generality of subsection (1) above, any provision of the Income Tax Acts which confers an exemption from income tax, or which provides for a person to be charged to income tax on any amount (whether expressed to be income or not, and whether an actual amount or not), shall, except as otherwise provided, have the like effect for purposes of corporation tax.
(5)Where, by virtue of this section or otherwise, any enactment applies both to income tax and to corporation tax—
(a)it shall not be affected in its operation by the fact that they are distinct taxes but, so far as is consistent with the Corporation Tax Acts, shall apply in relation to income tax and corporation tax as if they were one tax, so that, in particular, a matter which in a case involving two individuals is relevant for both of them in relation to income tax shall in a like case involving an individual and a company be relevant for him in relation to that tax and for it in relation to corporation tax; and
(b)for that purpose references in any such enactment to a relief from or charge to income tax, or to a specified provision of the Income Tax Acts shall, in the absence of or subject to any express adaptation, be construed as being or including a reference to any corresponding relief from or charge to corporation tax, or to any corresponding provision of the Corporation Tax Acts.
(6)The provisions of the Income Tax Acts applied by this section do not include sections 1 to 5, 60 to 69, Part VII or sections 348 to 350 of this Act; and nothing in this section shall be taken to mean that income arising in any period is to be computed by reference to any other period (except in so far as this results from apportioning to different parts of a period income of the whole period).
