HC Deb 19 December 1957 vol 580 c82W
Mr. McKay

asked the Chancellor of the Exchequer what he estimates will be the total Income Tax relief given to contributors to the National Insurance Schemes in 1958–59 arising from the increased contributions; and how much this will represent to the individual contributor who will be paying the standard rate of Income Tax.

Mr. Powell

Assuming that rates and allowances' remain the same, £50 million for all insured persons and £4 6s. for an adult male employee if his income is wholly subject to the two-ninths earned income relief.
