HC Deb 22 May 1975 vol 892 c583W
Mr. George

asked the Secretary of State for Social Services what would be the gains to the National Insurance Fund if the ceiling on national insurance contributions were abolished.

Mr. O'Malley

If there were no ceiling in respect of Class 1 and Class 4 contributions, the additional income including Treasury Supplement in 1975–76 would be about £800 million on the basis of a full year's receipts at the rates of contributions introduced on 7th April 1975.
