HC Deb 12 February 1980 vol 978 c598W
Mr. Horam

asked the Chancellor of the Exchequer what would be the cost to the Exchequer of abolishing the 25 per cent. income tax rate; and what is the cost of reducing the standard rate by 1p.

Mr. Peter Rees

At 1979–80 income levels the full year figures are estimated as follows:

£ million
Abolition of the lower rate band 895(yield)
Reduction of basic rate by 1p 495(cost)

These are alternatives and cannot be taken in combination: abolishing the lower rate band would increase the cost of reducing the basic rate.
