Tax is topical right now. The Tax Working Group reports have made headline news around the country. Should a new land tax be introduced? Should GST be increased? Is it time for a comprehensive CGT?
Whether we like a tax, however it is imposed, is largely irrelevant. If a tax is imposed we’re stuck with it. That said, it is generally accepted that a “good” tax is one that is seen to be fair (so that less effort goes into evasion) and one that is not so expensive to administer that it contributes little to the tax base.
In the interests of generating some debate I’m happy to state a preference for an increased GST in exchange for a reduction in income tax. GST is a relatively inexpensive tax to collect and administer, is difficult to avoid, and as a consumption tax, taxpayers have a choice as to their level of participation.
Accordingly, GST should be accepted as a “good” tax.
In contrast, in my view a land tax cannot be considered a good tax. The fact that it is limited to a single form of capital means that distortion is inevitable. Further, given the consequent loss in capital value and the subsequent economic cost bring the real return from a land tax into question.
A middle ground position such as a comprehensive capital gains tax would provide a less distorting tax and for this reason deserves consideration.
However, an option not put out by the tax working group, but perhaps worth debate is the option to abandon the income capital dichotomy and tax all realised gains regardless of source.


While I am not against a well thought out CGT regime in New Zealand, I agree that increasing GST may give the most immediate and fair results. The administrative framework is already in place for both the IRD and those persons registered for GST.
Those opposed to increasing GST often cite financial hardships to those in lower income brackets. I feel that if different rates were introduced for different goods and supplies this problem may be preventable. If goods that were classified as “necessities of life”, e.g. bread and milk were zero-rated, and luxury items like cigarettes, alcohol and motor vehicles were taxed at a higher rate than 15%, then government could ensure increased revenue without impacting negatively on the lower socio-economic groups.
This approach would also assist other govenment organisations which are trying to make New Zealanders aware of their health issues.
At the end of the day nobody wants to pay more tax, but the reality is that for continued first-world infrustructure and benefits more revenue is needed.
