To ask the Chancellor of the Exchequer how many cases of evasion of payments of (a) income tax and (b) other tax have been discovered in each of the last five years; and what has been the value of the revenue recovered in both categories. [37922]

The information requested for taxes administered by the Inland Revenue is as follows:

Year	Income tax investigations	Other investigations	Yield from counter-evasion work (£ million)
1989–90	57,997	12,551	933
1990–91	61,755	13,219	1,091
1991–92	59,993	14,421	1,324
1992–93	55,611	12,952	1,361
1993–94	58,420	12,200	1,295
1994–95	57,701	10,643	1,378

The figure of yield for 1994–95 cannot be compiled on a basis exactly comparable with earlier years, owing to a change in the way these figures are maintained. Unlike previous years, it includes the yield from all employer compliance work.
