(1)M1In this section references to a company’s final year are references to the financial year in which the affairs of the company are completely wound up, and references to a company’s penultimate year are references to the last financial year preceding its final year.
(2)M2Subject to subsection (3) below—
(a)corporation tax shall be charged on the profits of the company arising in the winding-up in its final year at the rate of corporation tax fixed or proposed for the penultimate year; but
(b)where the corporation tax charged on the company’s income included in those profits falls to be calculated or reduced in accordance with section 13, it shall be so calculated or reduced in accordance with such rate or fraction fixed or proposed for the penultimate year as is applicable under that section.
(3)If, before the affairs of the company are completely wound up, any of the rates or fractions mentioned in subsection (2) above has been fixed or proposed for the final year, that subsection shall have effect in relation to that rate or fraction as if for the references to the penultimate year there were substituted references to the final year.
(4)M3An assessment on the company’s profits for an accounting period which falls after the commencement of the winding-up shall not be invalid because made before the end of the accounting period.
(5)In making an assessment after the commencement of the winding-up of the company but before the date when its affairs are completely wound up, the inspector may, with the concurrence of the liquidator, act on an assumption as to when that date will fall, so far as it governs section 12(7).
(6)The assumption of the wrong date shall not alter the company’s final and penultimate year, and, if the right date is later, an accounting period shall end on the date assumed, and a new accounting period shall begin and section 12(7) shall thereafter apply as if that new accounting period began with the commencement of the winding-up.
(7)M4References in this section to a rate or fraction fixed or proposed are references to a rate or fraction fixed by an Act passed before the completion of the winding-up or, if not so fixed, proposed by a Budget resolution (and without regard to any subsequent Act); except that if a rate or fraction so fixed is proposed to be altered by a Budget resolution any such reference to it is a reference to it as proposed to be so altered.
In this subsection “Budget resolution” means a resolution of the House of Commons for fixing any such rate or fraction as is mentioned in this section.
(8)Where the winding-up commenced before the company’s final year, paragraphs (a) and (b) of subsection (2) (but not subsection (3)) above shall apply in relation to the company’s profits arising at any time in its penultimate year.
(9)Any assessment made by virtue of section 8(4) shall be subject to any such adjustment by discharge or repayment of tax or by a further assessment as may be required to give effect to this section.
