HC Deb 11 February 1975 vol 886 c89W
Mr. George

asked the Chancellor of the Exchequer what is his estimate of the amount of revenue lost to the Exchequer by tax evasion for each year since 1964; and if he will list the number of prosecutions for tax fraud over the same period.

Mr. Robert Sheldon

I regret that it is impossible to make any estimate of the revenue lost through tax evasion.

Details of the under-assessments to tax uncovered by the Board of Inland Revenue and the criminal proceedings taken over the last 10 years are given at Tables 25 and 26 in the 117th Report of the Commissioners of Inland Revenue (Cmnd. 5804).
