asked the Chancellor of the Exchequer (1) what he estimates to be the total annual tax revenue raised in respect of rental income from owner-occupiers who let off rooms in their own homes;(2) what would be the cost to the Inland Revenue if he were to exempt from income tax the first £500 and £1,000, respectively, of rental income received by owner-occupiers in respect of rooms let in their own homes.

I regret that the information on which to base an estimate is not available.
