HC Deb 19 December 1974 vol 883 c509W
45. Mr. Holland

asked the Chancellor of the Exchequer what proposals he has to modify those income tax procedures that currently discriminate between men and women on grounds of sex.

Mr. Robert Sheldon

Income tax procedures do not in general discriminate between individuals on grounds of sex. They do distinguish in certain respects between married and single women; these differences flow from the general rule that the income of a married woman is aggregated for tax purposes with that of her husband.
