§ Mr. Nicholas Brown
To ask the Chancellor of the Exchequer what would be(a) the first year and (b) the full-year revenue effect, if all tax allowances and reliefs except the single person's allowance were restricted to the basic rate (i) in 1991–92, and (ii) in 1992–93, in (1) Great Britain, (2) Northern Ireland and (3) the United Kingdom.
§ Mr. Maude
It is estimated that, at 1991–92 levels of income, the yield in a full year from restricting all tax allowances and reliefs—except the personal allowance—to the basic rate of tax would be about £900 million. The corresponding figure for 1992–93 is £950 million.
The effect on receipts in the first year would depend on the administrative arrangements for such a change. I regret it is not possible to provide separate estimates for Northern Ireland.
