Three investor companies in the Trinity tax scheme have been put into liquidation by the High Court this month on the back of about $6 million of claims from Inland Revenue.
The Trinity scheme in 2004 was ruled to be a tax avoidance arrangement - a decision upheld by the Supreme Court four years later.
The IRD at the time claimed the scheme would have cost taxpayers up to $3.7 billion over its 50-year lifespan.
The scheme was a forestry investment allowing each participant to license land from the Trinity Foundation for 50 years to plant a crop of Douglas fir. The fee was $2 million, or about $40,000 per year.
Although the $2 million was not to be paid until 2048, it was immediately tax deductible to the investors. So the investors effectively claimed a deduction of $40,000 each year.
