HC Deb 25 April 1969 vol 782 c130W
Sir B. Rhys Williams

asked the Chancellor of the Exchequer what is the total number of taxpayers whose marginal rate of tax through the incidence of income tax or surtax is 6s. 6d. in the pound or higher.

Mr. Harold Lever

About 3⅓ million in 1966–67, the latest year for which an estimate can be made. This figure includes about two million taxpayers with mixed incomes whose marginal rate on their earnings is 6s. 5d. though the marginal rate on their investment income is 8s. 3d. or higher.
