HC Deb 08 December 1986 vol 107 c85W
Sir Edward du Cann

asked the Chancellor of the Exchequer what estimate he has made of the effect on revenue which would follow from replacing the present 25 per cent, reducing balance method of depreciating investment for tax purposes by a 25 per cent, straight line system.

Mr. Lawson

[pursuant to his reply, 2 December 1986, c. 598]: The effect on revenue would build up over a number of years and estimates depend crucially upon future levels of investment. The direct revenue cost in the peak year is tentatively estimated at £3.5 billion.
