HC Deb 24 April 1986 vol 96 cc224-5W
Mr. Frank Field

asked the Chancellor of the Exchequer if he is yet able to reply to the question tabled by the hon. Member for Birkenhead for answer on 7 March 1986 on the share of tax paid by each decile group.

Mr. Brooke

I regret the delay in providing a reply to the hon. Member's question. It is being answered today.

Mr. Frank Field

asked the Chancellor of the Exchequer what extra revenue would result from allowing all tax allowances, both personal and non-structural, at the standard rate of tax only.

Mr. Moore

I shall let the hon. Member have a reply as soon as possible.

Mr. Frank Field

asked the Chancellor of the Exchequer if he will express the percentage shares of tax paid for each year since 1977–78 by the following income groups: the top 10 per cent., 10 to 20 per cent., 20 to 30 per cent., 30 to 40 per cent., 40 to 50 per cent., 50 to 60 per cent., 60 to 70 per cent., 70 to 80 per cent., 80 to 90 per cent., and bottom 10 per cent., respectively.

Mr. Moore

[pursuant to his reply, 7 March 1986, c. 284]: The available information is as follows. The analysis is of single people and married couples paying income tax in each year. The quantiles are determined by reference to tax liability. The figures are based on the surveys of personal incomes for years up to 1983–84. For subsequent years, they are based on projections from the 1983–84 survey and are therefore provisional.
