HC Deb 04 February 1954 vol 523 c58W
Mr. Woodburn

asked the Chancellor of the Exchequer what additional Exchequer revenue would result if Income and Surtaxes were increased to leave a maximum net income of £2,000 and £1,000, respectively.

Mr. Boyd-Carpenter

In theory, about £75 million and £400 million, respectively, at present levels of taxation and income. The disincentive effects of taxation at such rates, however, would very much reduce both these yields and those of other taxes if the change were actually made.
