§ Mr. Dobsonasked the Chancellor of the Exchequer what proportion of central Government tax review has been met by direct taxation of the corporate sector in each 726W of the last five years; and what is his estimate for this year and next year in each case excluding income from petroleum revenue tax.
§ Mr. Ridley[pursuant to his reply, 25 July 1983, c.311]: The available estimates are as follows:
per cent. 1978–79 12.0 1979–80 11.9 1980–81 9.8 1981–82 9.6 1982–83 8.5 1983–84 8.1 (forecast) The figures for the corporate sector exclude tax paid by public corporations. They also exclude petroleum revenue tax and supplementary petroleum duty, but include the national insurance surcharge. Central Government tax revenue includes all taxation and miscellaneous receipts; but excludes national insurance contributions. The estimated percentages are tentative.
