I should begin by pointing out that the capital gains tax (CGT) code already contains special measures to ensure that those who realise gains on development land pay a significant proportion of the gain to the Exchequer. As the Deputy is no doubt aware, gains are generally chargeable to CGT at a rate of 40 per cent after indexation relief, and, following the alignment of the CGT rate with the standard rate of corporation tax, a similar tax treatment applies to gains made by a company in the course of its trade. However, in the case of gains made on development land, the application of indexation relief is restricted. It applies only to the portion of the value of the land at the time of acquisition that reflected the land's "current use value", i.e. the value of the land calculated on the assumption that it was at that time, and would remain, unlawful to carry out development on the land, other than development of a minor nature. As a general rule, these special provisions apply where the land is sold for over £15,000. Accordingly, the effective rate of tax for development land gains can be appreciably greater than for other assets.
