Tax Avoidance - Government and Judicial Response

Government and Judicial Response

Tax avoidance reduces government revenue and brings the tax system into disrepute, so governments need to prevent tax avoidance or keep it within limits. The obvious way to do this is to frame tax rules so that there is no scope for avoidance. In practice this has not proved achievable and has led to an ongoing battle between governments amending legislation and tax advisors' finding new scope for tax avoidance in the amended rules.

To allow prompter response to tax avoidance schemes, the US Tax Disclosure Regulations (2003) require prompter and fuller disclosure than previously required, a tactic which was applied in the UK in 2004.

Some countries such as Canada, Australia and New Zealand have introduced a statutory General Anti-Avoidance Rule (or General Anti-Abuse Rule, GAAR). Canada also uses Foreign Accrual Property Income rules to obviate certain types of tax avoidance. In the United Kingdom, there is no GAAR, but many provisions of the tax legislation (known as "anti-avoidance" provisions) apply to prevent tax avoidance where the main object (or purpose), or one of the main objects (or purposes), of a transaction is to enable tax advantages to be obtained.

In the United States, the Internal Revenue Service distinguishes some schemes as "abusive" and therefore illegal.

In the UK, judicial doctrines to prevent tax avoidance began in IRC v Ramsay (1981) followed by Furniss v. Dawson (1984). This approach has been rejected in most commonwealth jurisdictions even in those where UK cases are generally regarded as persuasive. After two decades, there have been numerous decisions, with inconsistent approaches, and both the Revenue authorities and professional advisors remain quite unable to predict outcomes. For this reason this approach can be seen as a failure or at best only partly successful.

In the judiciary, different judges have taken different attitudes. As a generalisation, for example, judges in the United Kingdom before the 1970s regarded tax avoidance with neutrality; but nowadays they may regard aggressive tax avoidance with increasing hostility.

In the UK in 2004, the Labour government announced that it would use retrospective legislation to counteract some tax avoidance schemes, and it has subsequently done so on a few occasions, notably BN66. Initiatives announced in 2010 suggest an increasing willingness on the part of HMRC to use retrospective action to counter avoidance schemes, even when no warning has been given.
