HMRC has published details of its “yields” following the requirement since August 2004 to disclose certain arrangements giving rise to a tax advantage.

The disclosure regime has evolved since its inception; initially, schemes concerning investment vehicles and remuneration strategies had to be disclosed. Since 1 August 2006, the regime was broadened to the whole of income tax, corporation tax and capital gains tax, subject to “hallmarks”. Hallmarks operate so as to limit disclosure to only those schemes that are new, innovative, or of specific concern.

Disclosure rules also operate for Stamp Duty Land Tax (since 2005) and VAT (since 2004) but are subject to specific conditions and de minimis limits.

In total, some 1,200 direct tax schemes have been disclosed to date, along with some 800 indirect tax schemes. It is notable that the bulk of the schemes were disclosed in the initial year of the avoidance disclosure rules.

The full details, which HMRC are at pains to stress are provisional, can be found at http://www.hmrc.gov.uk/avoidance/disclosure-statistics.xls.
