Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if she will make an estimate of the potential revenue that could be raised through (a) equalising capital gains tax with income tax rates and (b) applying a 2 per cent tax for people with assets over £10 million, to be paid on the excess amount over £10 million.

The Government continually keeps the tax system under review.

Published estimates for illustrative tax changes can be found in HMRC’s Direct effects of illustrative tax changes bulletin including changes to Capital Gains Tax [1]
