HC Deb 23 February 1983 vol 37 c442W
Mr. Ralph Howell

asked the Chancellor of the Exchequer how much revenue would be lost if no income tax were deducted from persons earning less than the national average wage; and what percentage this represents of the personal income tax take.

Mr. Ridley

Provisional estimates for 1982–83 suggest that around £11.5 billion income tax is due in a full year from single people or married couples with income less than average male earnings for all occupations and around £8.5 billion from those with incomes less than average male manual earnings; these amounts represent respectively 37 per cent. and 28 per cent.—revised—of the total income tax due in a full year.
