HC Deb 06 December 1979 vol 975 c337W
Mr. David Price

asked the Chancellor of the Exchequer what would be the increased revenue to the Exchequer, on the basis of current income levels, if all personal incomes above £10,000, £15,000, £20,000, £25,000 and £30,000 a year, respectively, were taxed at the marginal rate of 100 per cent.

Mr. Peter Rees

The readily available information relates to taxable incomes, rather than gross incomes.

At 1979–80 income levels the estimated amounts would be:

Yield £ million
Taxable income above £10,000 1,950
Taxable income above £15,000 910
Taxable income above £20,000 530
Taxable income above £25,000 350
Taxable income above £30,000 250
