(1)Sections 94 to 97 above shall have effect, subject to the following provisions of this section, in relation to every chargeable period ending on or after 21st April 1994.
(2)Those sections do not apply for the purposes of income tax in relation to a chargeable period if—
(a)that period is a year of assessment as respects which Chapter IV of Part IV of the M1Finance Act 1994 (changes for facilitating self-assessment) does not apply to the shipowner’s actual trade (“a transitional year”); and
(b)the basis period for that chargeable period ended before 21st April 1994.
(3)Where the relevant period is a transitional year the references in paragraphs (b) and (c) of section 33A(1) of the M2Capital Allowances Act 1990 (“the 1990 Act”) to the relevant period shall have effect for the purposes of income tax as if they were references to the basis period for the relevant period.
(4)Where the relevant period is a transitional year or any other year of assessment as respects which section 140 of the 1990 Act has effect without the substitution made by section 211 of the Finance Act 1994, section 33A(3)(d) and (7) of the 1990 Act shall have effect for the purposes of income tax—
(a)subject to the assumption for which subsection (5) below provides; and
(b)as if the reference to the shipowner incurring a loss in his actual trade for the relevant period were a reference to his incurring a loss in that trade for the period (“the assessment period”) any profits or gains of which would have been the profits or gains on which income tax chargeable for the relevant period in respect of that trade would finally have fallen to be computed.
(5)That assumption is that in computing the profits or gains of the assessment period which arise from the shipowner’s actual trade, and in computing whether he has incurred a loss in that trade for that period, all such deductions and additions were to be made as would have to be made if—
(a)allowances falling to be made under the 1990 Act for the relevant period in taxing that trade (excluding any allowances carried forward to the relevant period by virtue of section 140(4) of the 1990 Act) were trading expenses of the trade for the assessment period; and
(b)charges falling to be so made (apart from any allowances so carried forward) were charges on amounts falling to be treated as trading receipts of that trade for the assessment period.
(6)In relation to expenditure incurred in the basis period for a transitional year—
(a)the reference in section 33C(2)(a) of the 1990 Act to the chargeable period in which the expenditure is incurred shall have effect as a reference to the chargeable period in the basis period for which it was incurred; and
(b)the reference in section 33F(4) of the 1990 Act to a chargeable period shall include a reference to a basis period.
(7)Section 33F(2) of the 1990 Act shall not apply to any claim under section 33A for the deferment of the whole or any part of any charge for a transitional year, but no such claim shall be allowed for the purposes of income tax unless it is made—
(a)within two years of the end of the relevant period; and
(b)in a case where the shipowner’s actual trade is carried on by two or more persons jointly, by the person required under section 9 of the Management Act (partnership return) to make a return for that period in respect of that trade.
(8)Expressions used in this section and in the provisions inserted by sections 94 to 97 above in the 1990 Act shall have the same meanings in this section as in those provisions.
