The Inland Revenue Department has spelled out its final view on what constitutes tax avoidance for the first time since 1990 in a 135 page document that the accounting profession and taxpayers have waited years to see.
The last time a final determination on tax avoidance was released was in 1990, and the publication of new finalised guidelines has been delayed in the last five years by a string of wins in the courts for the tax department, which have fundamentally changed the way tax avoidance is defined.
At its most basic, tax avoidance in the 1990 guidelines was judged on the basis of whether the arrangements in question met the letter of the law.
However, the court victories in the last few years have created a new bedrock question for tax avoidance. That is: was the arrangement in line with what Parliament intended when it passed the law.
The most celebrated case in which this principle was applied was in a series of cases involving tax avoidance by foreign-owned, mainly Australian, registered banks, which used complex cross-border arrangements to avoid tax.
