The Income Tax (Indexation) Order 1989
Sections 1(6) and 257(11) of the Income and Corporation Taxes Act 1988 (“the Act”) provide that the Treasury shall by order made by statutory instrument before 6th April 1989 specify the amounts which by virtue of those sections shall, unless Parliament otherwise determines, be treated as specified for the year 1989–90. These are the basic rate limit (section 1 of the Act) and the personal reliefs (section 257 of the Act) respectively. The higher rate bands were abolished by the Finance Act 1988 with effect from 6th April 1988. The amounts of the basic rate limit and the personal reliefs for the year 1988–89 were fixed by sections 24(2) and 25(1) respectively of the Finance Act 1988. Those amounts are increased by this order in accordance with the percentage increase (6.8%) in the retail prices index for December 1988 over that for December 1987. Certain of the amounts have been rounded to the nearest £100 in accordance with sections 1(4) and 257(9)(a) of the Act and, in the case of the other amounts, the increases have been rounded to the nearest £10 in accordance with section 257(9)(b) of the Act.
