§ Mr. Campbell-Savoursasked the Chancellor of the Exchequer what is his estimate of the effect on revenue accruing to the Exchequer of changes in income tax paid at above basic rate, arising only from the change in the tax threshold in each year since 1979.
§ Mr. Moore[pursuant to his reply, 7 February 1985, c. 673]: If in 1984–85 the main personal allowances had each been replaced by the corresponding 1978–79 allowances, indexed to 1984–85 levels by reference to the statutory formula, there would have been an additional liability to tax at rates in excess of the basic rate of about £30 million in a full year.
