HC Deb 25 July 1989 vol 157 c635W
Mr. Austin Mitchell

To ask the Chancellor of the Exchequer what is his estimate of the gross and taxable income of the self-employed in the current financial year as(a) declared for tax and (b) not so declared; and if he will provide comparable figures for 1978–79.

Mr. Norman Lamont

The latest information is for 1986–87. The estimates cover married couples and single people whose main source of income is from self-employment.

£ billion
Gross Income Taxable Income
1978–79 9.1 4.5
1986–87 26.4 15.4

By their very nature, estimates of amounts of income not declared for tax are not available.
