§ Mr. Tim Smithasked the Chancellor of the Exchequer if he will estimate the annual revenue of a short term, 12 months capital gains tax levied at marginal income tax rates.
§ Mr. Moore[pursuant to his reply, 12 April 1984, c. 349]: Any estimate must be subject to a very wide margin of error and must depend very much on assumptions about the rest of the tax system and the behavioural response of taxpayers, but the annual revenue might be £20 million to £30 million.
