Abstract:
All countries that have adopted Goods and Services Tax (GST) or Value Added Tax (VAT) employ a ‘change-in-use’ mechanism to distinguish consumption from the stages of production and distribution. New Zealand’s former change-in-use rules were unique. Unlike the ‘use’ based apportionment approaches employed in Australia, Canada and the United Kingdom, New Zealand employed an adjustment approach that utilised a ‘principal purpose’ test and deemed supply mechanism. While Canada has also employed an adjustment approach for capital property, the New Zealand rules have operated differently to those in Canada. In response to criticism for being overly complex and confusing, the New Zealand change-in-use rules will adopt a new ‘use’ based apportionment approach, together with a new mechanism to constrain the number of adjustments, from 1 April 2011 for a number of taxpayers. Applying criteria identified by the Tax Working Group the performance of New Zealand’s change-in-use rules are examined, in comparison to those applied in Australia and Canada. In addition, the comparative readability of the change-in-use provisions in all three jurisdictions is examined. The paper concludes that New Zealand should adopt an apportionment approach and that the Goods and Services Tax Act should be rewritten for improved readability.
