§ Mr. Austin MitchellTo ask the Chancellor of the Exchequer if, pursuant to his reply of 19 October,Official Report, columns 927–28, relating to the number of tax units and tax liability, he will revise the table to include lower limits at £1,000 intervals to £15,000 and at £17,500, £25,000 and £40,000.
§ Mr. Norman LamontThe estimates in the table referred to by the hon. Member are based on a projection of the 1985–86 survey of personal incomes, a survey in tax offices of about 70,000 taxpayer records. As estimates for 1988–89 are based on sample data projected forward three years they are subject to uncertainty. Further disaggregation of the information in the earlier reply would lead to estimates that were subject to a large degree of uncertainty and possibly misleading.
