HC Deb 15 April 1975 vol 890 c72W
Mr. Richard Wainwright

asked the Chancellor of the Exchequer what was the percentage paid in income tax and surtax in 1972–73 by the following income recipients: (i) top 1 per cent.; (ii) top 10 per cent.; (iii) top 40 per cent.; (iv) bottom 30 per cent.; (v) bottom 10 per cent. and (vi) all incomes compared with the latest figures for 1973–74.

Mr. Robert Sheldon

The information for 1972–73 is as follows:

Group Income Tax ana Surtax as a percentage of income
(i) Top 1 per cent. 43
(ii) Top 10 per cent. 26½
(iii) Top 40 per cent. 19½
(iv) Bottom 30 per cent.
(v) Bottom 10 per cent
(vi) All incomes* 16½

* These figures are derived from the Inland Revenue's Survey of Personal Incomes. The numbers relate only to individuals—counting married couples as one—with total incomes above the effective tax exemption limit.

I regret that information for 1973–74 is not available.
