Confidentiality is a fundamental concept at the heart of the modern taxation system. The need to strike a balance between the taxpayer's right to privacy and the requirement of HMRC to carry out its functions has been the subject of much legislation and litigation.1 There has been an explosion in the exchange of information between revenue authorities of different countries and British politicians have for years been under pressure to emulate the tradition of American presidents publishing their tax returns.

The system of self-assessment here, too, was designed to ensure secrecy: any person or company engaged in any trade or manufacture could be assessed to tax, either as to their entire income or as to that part arising from trade, declared in a sealed statement in a prescribed form which meant that the Commissioners would not know what...
