A Capital Gains Tax is Not the Answer
Former Prime Minister David Lange is reputed to have described a capital gains tax as the sort of tax you introduce if
you want to lose not just one election, but the next three! And he should know since the Fourth Labour Government
considered a capital gains tax back in 1988, eventually rejecting it as being too difficult. Sadly, they also rejected
the flat tax proposed by then Finance Minister Roger Douglas, which would have aligned personal income and company tax
at around 23 percent. The introduction of a low flat tax - in conjunction with a low GST consumption tax - would have
transformed New Zealand into a first world economy instead of the third world economy with first world spending habits
that we are today.
As a result of the present economic recession – and reckless spending by the Labour administration– the government’s
income and expenditure are now seriously out of kilter. Income taxes, which make up almost a half of the government’s
tax revenue, are falling as wages come under pressure and unemployment rises. GST, which accounts for around 22 percent
of government tax revenue is also down as families tighten their belts and spend less. And company tax, which
contributes around 15 percent of government tax revenues, has had its bottom line squeezed between rising costs and
However, instead of reducing spending to match their lower income (as most households and businesses are having to do),
the government is looking for new ways to increase tax revenue. They started by cancelling our promised tax cuts, saving
an estimated $1 billion. And the proposed emissions trading scheme, which puts a price on carbon across the economy, is
being described by many as yet another tax grab.
Earlier this year a high level group of private and public sector tax experts were appointed by the government to a Tax
Working Group to review New Zealand’s tax system. Their principle objective is to find ways of broadening the tax base
so the government can meet its medium term objective of aligning the top rate of income tax, trustee tax, and company
tax at no more than 30 percent.
It is most unfortunate that the mandate of the Tax Working Group excludes examining the quality of government spending.
This is especially the case since the Secretary of the Treasury has been so outspoken about the fact that around $40
billion of the Government’s $62 billion budget could be better spent. The fact that 65 percent of all government
spending is deemed to be of poor quality is a disgrace, especially as total government spending (which includes local
government) is forecast to rise from 40.3 percent of GDP in 2007 to 46.4 percent in 2010. In other words, almost half
of the country’s wealth created each year is consumed by the government sector. This places New Zealand in the upper
echelon of state controlled economies.
In comparison, public expenditure in Hong Kong is expected to be only 19.4 percent of GDP in 2010, falling to 18.9
percent in 2014. The small size of their government is the key reason why Hong Kong is now a very wealthy country, while
New Zealand, with its ever-expanding government, is so poor.
In fact, convention places a 20 percent of GDP cap on government spending in Hong Kong. Article 107 of the Hong Kong
Basic Law requires the Hong Kong government to "keep the budget commensurate with the growth rate of its gross domestic
product". Over the years this has been interpreted as meaning that public spending should remain at 20 percent of GDP -
a figure has now assumed de facto constitutional status.
Given the excessive rate of growth of the public sector in New Zealand, surely a cap on government spending is the sort
of restriction on the administration that needs to be considered here? It is unfortunate that such initiatives are
outside the scope of the Tax Working Group, whose brief is instead limited to various tax gathering possibilities.
One such scheme that is presently being considered is a capital gains tax. Although the Tax Working Group is looking at
the proposal as a means of broadening the tax collection base, the Labour and Green parties are using it as an
opportunity to push for higher taxes by claiming it will make housing more affordable.
This week’s Guest Commentator, property investment specialist Frank Newman, points out the fallacy of that argument,
explaining that New Zealand already has a capital gains tax for investment traders - including property investors - and
that homes have become less affordable, largely because of local and central government policy:
“It may come as a surprise to many that there is in fact a capital gains tax regime in New Zealand; its application is
far from clear and therefore not widely understood. Put very simply, a taxpayer is liable for income tax on capital
gains if they are a dealer or trader, or if they bought the investment with the intention of reselling at a profit. It’s
the latter that causes the difficulty. The IRD as the all-powerful arbiters must look at the circumstances of each case
to come to a view on the investor’s intention at the time the purchase was made. With the onus on the taxpayer to prove
their innocence, that lack of legal clarity puts the taxpayer at risk of an unexpected and potentially ruinous tax
“Property investors face further challenges because there are additional and more specific rules applying to gains on
the sale of property. These include for example a minimum ten year holding rule for a builder’s private home and onerous
rules about “tainting”. The tainting rules state that should a long-term property investor with an existing portfolio of
properties buy another property with the intention of selling it for a quick profit, then the capital gains on ALL of
their properties in their portfolio would become taxable. They all become “tainted” by the one transaction. This is not
the case for sharemarket investors who can own shares in a trading account and shares in a portfolio account, without
one tainting the other.
“It is therefore incorrect to say New Zealand does not have a capital gains regime, (but fair to say it lacks the
clarity of capital gains regimes in other countries). It’s also bogus to claim property is New Zealanders most preferred
investment because of tax advantages. It is popular for a number of other reasons”. To read Frank’s full article, click

Although the government’s objective of aligning income, trust and property taxes at 30 percent is commendable,
unfortunately for New Zealand the world has already progressed beyond that target. At the present time, the OECD average
company tax is under 27 percent and falling, with South Korea, one of our key trading partners planning to introduce a
company tax of 20 percent by 2010, and another of our trading partners, Canada, intending to implement a federal
corporate tax of 15.9 percent by 2012. If New Zealand is to remain competitive in the global marketplace, aligning the
tax rate nearer to 20 percent – not 30 percent - would seem the prudent way to go, especially as it is now well known
that lower, flatter taxes drive faster economic growth, generating extra tax revenue from higher wages and greater
Dr Daniel J. Mitchell, a Senior Fellow with the Cato Institute and a top international tax reform expert believes that
the benefits of lower, flatter taxes cannot be over-stated: “Thanks largely to tax competition, governments are
dramatically improving tax policy. Over the past 30 years, tax rates on productive activity have been sharply reduced.
Personal and corporate income tax rates have been slashed. Capital gains tax rates, wealth taxes, and death taxes have
been lowered or eliminated. These pro-growth reforms have boosted the global economy, lowered poverty, and improved
He believes that the “flat tax revolution” is the most exciting of all tax reforms with some 24 countries having adopted
some form of single-rate tax regime – many of the more recent ‘conversions’ opting for flat 15 percent or 10 percent tax
rates. The result has been faster growth, more jobs, and increased competitiveness. And while politicians are usually
extremely concerned about losing their tax revenue, the results show that flat tax systems invariably generate higher
tax revenues because of more income and better compliance.
Dr Mitchell also makes a point that is especially relevant to New Zealand, and that is that because labour and capital
can cross national borders to escape punitive tax rates, it no longer makes sense to discriminate against
highly-productive taxpayers. With an astonishing 24 percent of New Zealanders living overseas (compared with only 4
percent of Australians who live overseas) finding ways to improve the incentives to work, invest and save in New Zealand
has to be a critical objective of the Tax Working Group.
The OECD estimates that a 5 percent fall in people’s marginal tax rate increases GDP by 1 percent over the medium term
as taxpayers respond to incentive effects. Imagine the boost to the economy if the government changed the tax mix by
collecting more of its revenue from the non-distortionary consumption tax (if GST was raised to 15 percent, it would
bring in an additional $2.15 billion in revenue), so it could reduce income and company tax rates to levels that would
stimulate entrepreneurial activity, boost productivity and economic growth, and significantly raise living standards. By
carefully managing transitional issues to prevent hardship, a prosperous future could be the reality for all New
Whether this government has the vision, the commitment, and the courage to do what would be needed, will be a crucial
