HC Deb 16 April 1957 vol 568 cc176-7W
Mrs. Jeger

asked the Chancellor of the Exchequer how much it would cost to abolish the aggregation of the incomes of husbands and wives for Surtax purposes, and treat the two incomes separately.

Mr. P. Thorneycroft

About £4½ million in a full year, on the assumption that the separation applied only to earned income. There is no information on which to estimate the effect of aggregation of investment income.

Mrs. Jeger

asked the Chancellor of the Exchequer how many working wives are paying Surtax on the whole of their incomes; and what yield in taxation this produces.

Mr. P. Thorneycroft

About 80,000, taking the wife's earned income as the top slice of the joint income. The Surtax payable on the wife's earned income on the same assumption is nearly £4 million.
