HC Deb 19 January 1965 vol 705 c5W
37. Mr. Ridley

asked the Chancellor of the Exchequer how much will be paid in Income Tax and National Insurance contributions in a full year by a married man with no children earning £18 per week in 1963–64 and 1964–65, respectively.

Mr. Callaghan

Such an adult male employee would pay £162 2s. 6d., or £163 13s. 10d. in the years 1963–64 and 1964–65, respectively, if his employer had not contracted out of the graduated scheme of national insurance, but if his employer had contracted out, the corresponding figures are £149 3s. 6d. and £150 0s. 10d.
