HC Deb 06 February 1985 vol 72 c599W
Mrs. Beckett

asked the Secretary of State for Social Services if he will estimate what national insurance contributions would have to be levied to maintain the same income to the fund if the Treasury supplement to the national insurance fund were now at (a) 18 per cent. and (b) 15 per cent.

Mr. Whitney:

The Government Actuary calculates that in order to maintain the same income to the national insurance fund the total class I contribution rate could be reduced by (a) 1.05 percentage points and (b) 0.6 percentage points if the Treasury supplement were increased to 18 per cent. and 16 per cent. respectively. In each case it is assumed that there would be similar revisions to the other contribution rates. The other assumptions underlying the calculation are set out in the government Actuary's report on the draft of the Social Security (Contributions Rerating) (No. 2) Order 1984 (Cmnd. 9386).
