5(1)This paragraph has effect for allowing deductions by reference to those which would have fallen to be made if section 136 of the [1952 c. 10.] Income Tax Act 1952 had applied for the years 1963-64 and 1964-65.
(2)Subject to the provisions of this paragraph, an allowance under this paragraph shall be made to the person (“the occupier”) carrying on a trade where land which was occupied by him at any time before the end of the year 1962-63 for the purposes of the trade permanently ceases to be occupied by him for those purposes.
(3)The amount of the allowance shall be the excess of—
(a)the aggregate of any deductions in respect of the annual value of the land which, by virtue of section 136, would have been made in computing the profits or gains of the trade for the [1963 c. 25.] years 1963-64 and 1964-65 but for section 29(1) of the Finance Act 1963 and the repeal by that Act of section 136;
over
(b)the aggregate of any deductions relating to the land made in computing the profits or gains of the trade for those years, being—
(i)deductions permitted by section 29(2) of the Finance Act 1963, so far as made in respect of the period in respect of which the deductions mentioned in paragraph (a) above would have been made; or
(ii)deductions in respect of rent from which an amount representing tax was deducted under section 173 of the Income Tax Act 1952, so far as made in respect of that period.
(4)The allowance shall be made by—
(a)treating the amount of it as rent paid for the land by the occupier (in addition to any actual rent), becoming due from day to day during the period defined in sub-paragraph (5) below; and
(b)allowing deductions accordingly in computing the profits or gains of the trade chargeable under Case I of Schedule D for any chargeable period the profits or gains for which fall to be computed by reference to a period including the period defined in sub-paragraph (5) below or any part thereof.
(5)The period referred to in sub-paragraph (4) above is that ending when the land permanently ceases to be occupied by the occupier for the purposes of the trade, and of a duration, equal to the aggregate of—
(a)the number of months and fractions of months during which the land was occupied by him for the purposes of the trade in so much of the period by reference to which the profits or gains of the trade for the year 1963-64 fell to be computed as fell before the beginning of that year; and
(b)the number of months and fractions of months during which the land was so occupied in so much of the period by reference to which the profits or gains of the trade for the year 1964-65 fell to be computed as fell before the beginning of the year 1963-64.
(6)No allowance shall be made under this paragraph where the date on which the land permanently ceases to be occupied by the occupier for the purposes of the trade—
(a)falls within a chargeable period in which he permanently ceases to carry on the trade; or
(b)where the occupier is not a company, falls within a year of assessment and also within a period by reference to which the profits or gains of the trade for that year of assessment fall to be computed.
(7)Where, by reason of a change in the persons carrying on the trade, the trade falls to be treated for any of the purposes of the Income Tax Acts as permanently discontinued, a person engaged in carrying on the trade immediately before the change occurred who continues to be so engaged immediately after it occurred shall be treated for the purposes of this paragraph as not having been in occupation of the land at any time before it occurred.
(8)Where there has been a change in the persons carrying on the trade, but by virtue of section 113 of this Act or section 17(1) of the [1954 c. 44.] Finance Act 1954 (company reconstructions before introduction of corporation tax), the trade does not by reason of the change fall to be treated for any of the purposes of the Income Tax Acts as permanently discontinued, this paragraph (including this sub-paragraph) shall apply as if any occupation of the land before the change occurred by the persons carrying on the trade immediately before it occurred were occupation by the persons carrying on the trade immediately after it occurred.
(9)Where section 343(1) applies, then for the purposes of this paragraph any occupation of land for the purposes of the trade by the predecessor shall be treated as having been the occupation of the successor.
Subsection (6) of that section shall apply to this sub-paragraph as it applies to subsections (2) to (5) of that section, and in this paragraph “predecessor” and “successor” have the same meaning as in that section.
(10)Where section 518 has effect, then for the purposes of this paragraph any occupation of land for the purposes of the trade by the transferor shall be treated as having been the occupation of the transferee.
This sub-paragraph shall be construed as one with section 518.
(11)Sub-paragraphs (1) to (10) above shall apply in relation to a profession or vocation as they apply in relation to a trade, but as if the reference in sub-paragraph (4) to Case I of Schedule D were a reference to Case II of that Schedule.
(12)For the purposes of this paragraph, any occupation of land by the London Transport Board which was by virtue of paragraph 6 of Schedule 3 to the [1970 c. 24.] Finance Act 1970 immediately before the commencement of this Act treated as occupation by another body, shall continue to be so treated by virtue of this sub-paragraph.
