HC Deb 07 February 1966 vol 724 c15W
Mr. Barnett

asked the Chancellor of the Exchequer if he will estimate the cost of exempting from Income Tax the first £500 per annum of earned income of all men aged 65 years and over and women aged 60 years and over.

Mr. MacDermot

If the first £500 of earnings (but not pensions) were completely ignored for tax purposes the full year cost might be of the order of £100 million.
