HC Deb 29 October 1990 vol 178 c360W
Mr. Soley

To ask the Chancellor of the Exchequer what would be the cost of adjusting the maximum ceiling for mortgage interest tax relief to(a) £35,000, (b) £40,000, (c) £45,000 and (d) £50,000 on the assumption that (i) relief continues to be available at the higher marginal tax rate where applicable and (ii) that relief is restricted to the standard 25 per cent. rate of income tax.

Mr. Maude

Provisional estimates of the costs of increasing the ceiling are given in the table. The estimates exclude behavioural effects which would be substantial for the higher ceilings.
