INHERITANCE TAX
By this Order, made under the provisions of section 8 of the Inheritance Tax Act 1984 (formerly the Capital Transfer Tax Act 1984) a new Table of rate bands and rates is substituted in Schedule 1 to that Act for the Table which was substituted by the Finance Act 1988. The figures in the first and second columns of the new Table are the amounts specified in the Table in Schedule 1 to the Inheritance Tax Act 1984 (as so substituted) increased by the amount of the percentage increase (6.8%) in the retail prices index for December 1988 over that for December 1987. The figures are rounded upward to the nearest £1,000 in accordance with section 8(2). The “retail prices index” is defined in section 8(3) as “the general index of retail prices (for all items) published by the Department of Employment”. The retail prices index for December 1987 is 103.3 and for December 1988 is 110.3 (based on January 1987 as 100). (Table 6.4 on pages S60 and S61 of the February 1989 number of the Employment Gazette, the official journal of the Department of Employment.)
