HC Deb 27 October 1967 vol 751 cc595-6W
Sir J. Rodgers

asked the Chancellor of the Exchequer what he now estimates would be the cost to the revenue if Surtax payers were allowed to keep the last 7s. 6d. in the £ sterling earned.

Mr. Callaghan

If in cases of mixed incomes the earned income was treated as the bottom slice of total income the cost would be about £13 million for a full year.
