To ask the Chancellor of the Exchequer if he will publish a table showing (a) the total cost of mortgage interest tax relief in 1988–89, (b) the average value of relief per mortgagor, (c) the numbers receiving mortgage relief broken down into the following income ranges: under £4,000, £4,000 to £5,000, £5,000 to £6,000, £6,000 to £7,000, £7,000 to £8,000, £ £8,000 to £9,000, £9,000 to £10,000, £10,000 to £12,000, £12,000 to £15,000, £15,000 to £20,000, £20,000 to £25,000, £25,000 to £30,000, over £30,000.

[holding answer 30 March 1988]: Provisional estimates based on the proposed rates of ax for 1988–89 are given in the table. They are derived from projections of data from the 1985–86 survey of personal incomes and the 1985 family expenditure survey. The estimates include mortgages formerly under the option mortgage scheme, which are now subsumed within MIRAS.

1 Average manual earnings are for full-time males aged over 21 working a full week.
2 Tax-free income is defined as the tax threshold plus child benefit.
3 Break-even point is the level of income at which income tax liability is equal to the money received through child benefit. It therefore gives the level of income above which the family pays more income tax than it obtains in benefits for children.
4 On the basis of the 1988 Budget proposals. Estimates of thresholds and break-even points as a percentage of earnings are provisional.
5 Both children aged under 11.
6 Two children aged under 11, one aged between 11 and 15 and one aged 16 or over.
