To ask Her Majesty's Government what would be (a) the revenue implications, and (b) the additional number of people who would pay tax, if the capital gains tax threshold were reduced to (1) £1,000, (2) £2,500 and (3) £5,000 for individuals and trustees in 2009–10, 2010–11 and 2011–12. [HL1357]

To ask Her Majesty's Government what would be the revenue implications of applying capital gains tax at the marginal rate of income tax in 2009–10, 2010–11 and 2011–12. [HL1358]

To ask Her Majesty's Government what would be (a) the revenue implications, and (b) the additional number of people who would pay tax, if the capital gains tax threshold were reduced to (1) £1,000, (2) £2,500 and (3) £5,000 for individuals and trustees and capital gains were charged at the marginal rate of income tax in 2009–10, 2010–11 and 2011–12. [HL1359]

HMRC holds limited data on the number of individuals and trustees using all or part of their annual exempt amount (AEA) and therefore it is currently not possible to estimate the revenue implications from the proposed reductions to the AEA.

Due to the difficulties of assessing the large behavioural responses which would result from a change of this kind, a reliable estimate of the revenue implications of applying capital gains tax at the marginal rate of income tax can be determined only at disproportionate cost.
