HM Revenue & Customs (HMRC) issued a consultation document (including draft legislation) on 20 November 2007 which proposes a number of changes to the tax avoidance disclosure regime relating to notification of scheme reference numbers (see HMRC: Tax Avoidance Disclosure Regime: Improving the Scheme Reference Number System). The consultation period ends on 12 February 2008.

The proposals would, in particular, impose notification obligations on co-promoters of tax avoidance schemes and on intermediaries who do not themselves derive a tax benefit from a scheme.
