To ask the Chancellor of the Exchequer what would be the revenue raised from a 9 per cent. charge on unearned income for those below state retirement age with a (a) £3,000 exemption, (b) £3,500 exemption, (c) £4,000 exemption, (d) £4,500 exemption and (e) £5,000 exemption, giving both full year and first year revenues for 1991–92 and 1992–93, specifying the numbers affected in each case, for the United Kingdom.

[holding answer 9 March 1992]: Latest estimates for 1991–92 are as follows:

Threshold £	Yield in a full year £ million	Numbers affected Thousands
3,000	870	1,130
3,500	820	970
4,000	780	840
4,500	750	750
5,000	720	660

The amount of revenue collected in the first year would depend on the administrative arrangements for collecting such a charge. The yield in 1992–93 would depend on the levels of investment income for that year.These estimates take no account of any possible behavioural changes following the introduction of such a charge.
