HC Deb 01 June 1961 vol 641 c33W
18. Dame Irene Ward

asked the Secretary to the Treasury what is the estimated cost to the Treasury of tax relief for 1961–62 in respect of the employer's contribution to the National Insurance Fund, exclusive of the National Health Service.

Sir E. Boyle

If employers who carry on a trade or business were prohibited from deducting their National Insurance contributions in respect of their employees as an ordinary business expense for tax purposes, and if other employers were denied relief on their contributions, the extra yield of Income Tax would be £170 million.
