Key points The Labour party’s CGT would not be a good addition to New Zealand’s tax mix. The way that CGT is both promoted and protested in the media it sounds like a game changer. It isn’t. The CGT would do little to improve the efficiency and effectiveness of New Zealand’s tax system. The main reason for this is that it would be riddled with exceptions and unresolvable design problems and for all this it would raise very little revenue. In principle, it appears to broaden the tax base. Thus it could make for a more efficient tax system if additional revenue was used to lower other tax rates. However there are no current proposals for such an offset and the tax will not raise much revenue. While the Labour party expects the CGT would bring in over $3.7 billion (or 3% of total tax revenue) in 2026 the real number is likely to be half that amount. Labour expects to raise at least $1.3 billion from the farm sector. A more realistic estimate is that the tax would raise a nominal $590 million in revenue in 15 years’ time. Labour’s numbers don’t take account of ‘lock-in’ – that people will choose not to sell to avoid taxable gains. While the tax would take time to ramp up, it would reduce current farm values. We estimate the loss in value will be between $2.4 billion and $7.6 billion (-1% to -5%). Other asset owners would not face tax on their capital gains – chief amongst them are people who own their own home. This is politically predictable but economically costly as it retains a key distortion between asset types. Home affordability is unlikely to improve. Housing costs rise and fall with the relative costs of land, construction and transport (supply-side costs). These would not fall with a CGT. There is no such thing as a perfect CGT and design choices bring both costs and benefits. Victoria University’s Tax Working Group consider these costs and benefits and concluded that a CGT of the kind proposed by the Labour Party would not be an efficient and effective option going forward.

NZIER report -Capital gains tax ii1. Labour’s Capital Gains Tax
The New Zealand Labour party has a policy of introducing a capital gains tax (CGT).
The CGT would involve a 15% tax on gains in asset values, paid when the asset is sold.
Gains would be measured from the date the tax is introduced.
The tax would not apply to gains realised on:
family homes
including an allowance for land around a home on a farm
retirement savings
including sale of small business assets if the purpose is to fund
retirement income
Capital losses could be used to offset tax on current and future capital gains but not
on other types of income.
The policy should be thought of as an extension of the existing tax system. Many
capital gains are already taxable in New Zealand.1 Labour’s CGT extends the scope of
assets and entities subject to capital gains.
1.1. Purpose
The main objectives of the tax are:2
improve the efficiency of current tax system (“removing the tax bias
towards investment property”)
raise more revenue (“keep our assets, pay down debt”)
fund transfers or targeted tax reductions (“give hard working families a tax
break”).3
1.2. Sound in principle
These are sound objectives for any tax system. Ideal tax systems raise enough
revenue to pay for spending or benefits while imposing as small a cost as possible.
1
This is true when the purpose of owning assets is to make money from selling rather than holding or using the assets. E.g.
managed funds are generally taxed on realisation of profits from sales of equity investments as this is assumed to be a key
part of their business. Capital gains from real estate can similarly be taxed if a seller purchased had purchased a property
with intent to profit from selling it.

In this brief we do not evaluate specific targeted tax reductions or potential increases in transfers because Labour policy on
these is not now explicitly linked to revenue from a CGT. When first announced the CGT was to be used to fund cuts to GST
and a proposed tax free threshold for income below $5,000. These policies have since been dropped because they are not
sufficiently well targeted to those on low incomes (“we believe there are better ways to help struggling Kiwi families”,
Dominion Post 22 January 2014). The CGT will nonetheless implicitly be used to fund other policies such as a proposed R&D
tax credit.
NZIER report -Capital gains tax 11.2.1. Improves efficiency of the tax system
‘Cost’ in this context is not so much about dollars paid in tax but ‘distortions’ which
make people worse off.
General principles for minimising costs while raising enough revenue to fund
spending include making sure that the tax system is:
broad based
low rate
administratively simple
based on ability to pay.
Broadens the tax base
The broader the tax base the better because people can’t dodge the tax by doing
things they otherwise wouldn’t want to do. Consider the costs of excluding people
with pony-tails from any income tax. In principle, a CGT contributes to base
broadening by extending coverage of the current tax system to include a currently
untaxed source of income.
Based on a ‘low’ rate
Low tax rates are also generally more efficient than higher rates. Consider the
impacts on investment and unemployment of a 99% corporate tax rate. In this
respect, a 15% CGT seems reasonable – on the face of it.
Tends to be progressive
CGT tends by its nature to be a progressive tax.4 Progressivity is a desirable property
of tax systems to the extent that it is efficient to tax people based on ability to pay –
although the degree of progressivity is a matter of considerable debate in terms of
both equity and efficiency.
Gives greater clarity to tax rules
An explicit CGT could, in principle, have the benefit of providing greater clarity over
what a capital gain is and when capital gains are taxable or not. Tax law is always
open to a degree of interpretation but the tax treatment of capital gains in New
Zealand is an area that may benefit from less vague rules.
Reduce tax avoidance
Widening the scope of capital gains could also reduce incentives to shuffle income
from taxed income to untaxed gains. This, in principle, would improve the efficiency
of the tax system by reducing time and money spent on negotiating the line between
income and capital gains. It could also reduce time and money spent on enforcement
of rules against evasion.
4
Wealthier and higher income households are more likely to face CGT and thus face higher overall tax rates compared to
households with lower income and wealth.
NZIER report -Capital gains tax 21.3. Less sound in practice
While sound in principle, problems with CGTs begin to become apparent when
practical cost effectiveness and administrative simplicity are considered.
Most OECD countries have a CGT and in all of these of countries the tax comes with
complicated calculations and extensive exemptions. For all this complexity the tax
raises very little revenue (see the next section).
1.3.1. Imprecise measurement of gains
To introduce a CGT tax a number of pragmatic design choices have to be made which
undermine its in-principle appeal. For example, to calculate a gain, an initial or ‘book’
value has to be used. Actual cost of purchase is fine over the long term but this is not
a reasonable basis for valuation when the tax is first introduced so an alternative
valuation method is needed. This can become very complicated when, for example,
assets have not been traded for a very long time. Inevitably, averages of one sort or
another are applied. This means some assets will be under-taxed and others over-
taxed.
1.3.2. Inevitable exclusions
The family home
The ‘family home’ is commonly excluded from CGT – as it is in Labour’s proposal. This
significantly undermines the in-principle value of a CGT.5 Exempting the family home
has the effect of:
reducing the revenue that can be raised
introducing distortions in behaviour by tipping prices in favour of e.g.
owning one large house instead of a small house and a small bach
spending on home renovations instead of investing in a small business.
The average tax-payer might think reduced CGT tax is a benefit but it isn’t. Lower tax
revenue reduces the efficiency of the tax and limits scope for offsetting changes to
other tax rates (e.g. GST). This really matters as the efficiency of taxes falls
exponentially as the tax rate increases.6 Thus there are efficiency gains to having low
rates of tax on as many tax bases as possible and therefore benefits from using CGT
revenue to reduce tax rates elsewhere.
Sizable exceptions also make the tax system more complicated and increase
administrative and compliance costs.
5
Exclusion of the family home also means a CGT would be contrary to the principle of “horizontal equity” – the idea that
individuals with similar income or assets pay the same amount in taxes.
6
The rule of thumb is that a doubling of the tax rate quadruples the efficiency cost of the tax system. See Creedy, J. (2003)
‘The Excess Burden of Taxation and Why it (Approximately) Quadruples When the Tax Rate Doubles’, NZ Treasury Working
Paper 03/29, http://www.treasury.govt.nz/publications/research-policy/wp/2003/03-29.
NZIER report -Capital gains tax 3Retirement savings and small business assets
The Labour party policy also includes an exception for retirement savings
withdrawals and for sale of ‘small’ business assets – up to a value of $250,000 – if
they are being sold for retirement purposes. It is unclear whether this is intended to
apply to farmers or not – although the examples provided Labour’s policy documents
suggest that farms do not qualify for the proposed $250,000 exemption on ‘small
business assets.
Alignment with other policy goals
Exceptions are not exclusively political – although the non-political exceptions are
technically the ones which are most (though not always) difficult to know how to
deal with (i.e. whether the exceptions will increase or reduce the costs of the tax
system). The Labour party has set aside a number of these issues to be considered by
an expert panel.
Key issues to be addressed are whether to tax venture capital and whether (and how)
to allow for rollover of investment from one asset to another. The issue of rollover is
considered important for not discouraging investment in cases where investors use
their capital gains to back new business ventures including highly risky start-ups and
similar entrepreneurial ventures.
This issue is of particular importance for policy-makers who pursue policies aimed at
encouraging R&D and high-growth enterprises. In general, it is unwise to conflate
spending and promotional policies with tax policies, but gauging the extent to which
a new tax will undermine existing subsidies or similar initiatives – and adjusting them
accordingly – is hard to do. This makes exemption an expedient and seemingly cost-
effective CGT design choice.
1.3.3. Not as progressive as you’d think
While CGTs are generally progressive, they are less progressive than one might think.
This is partly because people with large portfolios of investment can manage the sale
of their assets to maximise assessed losses and hold onto assets to reduce assessed
(realised) gains. As a rule of thumb, the larger a person’s wealth the greater their
ability to manage their investments in this way and the smaller their overall tax rate.7
Modelling of the impacts of CGT on property markets also suggests that capital gains
taxes lead to higher rents. This effect would be felt most strongly by people on low
incomes.8
1.3.4. Homes won’t become more affordable
CGT on investment property is likely to cause home ownership rates to rise over the
long term, principally because the cost of renting will rise relative to the cost of
7
The same can be said for other forms of income tax but it is likely to be more extreme when tax is only assessed on
‘realisation’ of a gain. In principle, tax avoidance could be reduced by taxing gains as they accrue instead of when they are
realised but this is generally considered practically and politically infeasible.

NZIER report -Capital gains tax 4owning. This does not mean that places to live – i.e. homes – have become more
affordable.
There is a perception that the absence of capital gains stimulates speculative
investment in the property sector and that this causes prices to rise and homes to
become unaffordable. This overlooks the fact that speculative investment is already
subject to income tax on capital gains.9 It also overlooks the fact that developers
(including builders) are already subject to income tax on capital gains in New Zealand
(the law is specific on this point). If anything, the supply of housing is constrained by
existing taxes on property development.
Home affordability, in terms of cost relative to income, rises and falls with the
relative costs of land, construction and transport (supply-side costs). These would not
fall with a CGT. Countries with capital gains taxes have certainly not been immune
from rising house prices (see Figure 1)
Land prices would be expected to fall if a CGT caused reduced returns to buyers but
returns to development are already taxed according to capital gains.

1.3.5. Damned if you do and if you don’t
There is no such thing as a perfect CGT and design choices will bring both cost and
benefits. For example:
a low tax rate on CGT encourages people to shelter their savings in assets
which accrue capital gains instead of interest income or wage income
9
Whether or not these are being paid is another matter but not an issue that is peculiar to the property sector.
NZIER report -Capital gains tax 5 the ‘progressivity’ of CGT can create distortions by taxing ‘high yield’
investment more than capital in ‘low yield’ investment – in other words
reducing the relative returns to good decisions
CGT doesn’t affect risk-taking if taxes are levied on gains as they accrue and
losses can be offset against all forms of income, but there is no single
‘correct’ way to value assets which have not been sold in the market
CGT can be levied on ‘realisation’ of gains but this causes ‘lock-in’ where
people avoid selling assets in order to avoid taxes
problems with valuing existing assets, when a scheme is introduced, can be
avoided by exempting existing assets from CGT but this would increase
lock-in
a tax on realised asset gains can unnecessarily force dissolution of family
businesses which would otherwise be passed through the family and while
this can be solved by ‘rolling over’ the gain this exacerbates ‘lock-in’ and
reduces the size of the tax base.
These kinds of issues are some of the reasons why the most recent thorough
consideration of New Zealand’s tax options, by Victoria University’s Tax Working
Group, concluded that a CGT of the kind proposed by the Labour Party would not an
efficient and effective option going forward.
NZIER report -Capital gains tax 62. Not a large revenue spinner
In 2011 the Labour party estimated that its 15% capital gains tax would raise $17.5
million in its first year rising to $3.7 billion in 2026 as the scope of assets captured by
the policy grows over time.10 This is 3% of projected crown tax revenue and 1% of
nominal GDP in 2026.11
These estimates are high. The revenue potential of the tax is likely to be half that
estimated by Labour – if not smaller.
By way of example, Australia’s CGT averages around 1% of Australia’s GDP. However
Australian capital gains tax rates average 25% rather than the 15% proposed by
Labour.
Labour’s proposed policy is similar to the CGT applied in Australia. If New Zealand
collected CGT from the same sources as the Australian Federal government, but at a
lower 15% rate, revenue in 2026 would be $1.7 billion as opposed to the $3.7 billion
estimated by Labour.12
It is possible that a CGT in New Zealand would capture proportionately more revenue
than in Australia, though this is unlikely.
The estimated components of the revenue captured by a CGT also do not match with
a detailed bottom-up assessment of revenue. Individual investment property yielded
an estimated $1.7 billion in realised capital gains in 2012, on $7.2 billion of sales. This
equates to $253 million in revenue under a 15% CGT and 0.04% of the value of the
housing stock. Assuming the value of the housing stock grows at 5.25% p.a. this
suggests that CGT from investment property in 2026 would be $541 million – as
opposed to the $1.34 billion estimated for the Labour party.13
The estimated revenue gained from property is generally suspect because it:
does not account for negative impacts on the value of properties from
introduction of a CGT
assumes monotonically increasing prices, even though, for example:
growth trends in, for example, rural property prices have undergone
major step changes with 20 years of flat prices (1980 to 2000) to rapid
appreciation (2000 to 2009)
only Auckland and Canterbury have exhibited growth in residential
prices since 2007.
overlooks spatial variation in the level of property prices and turnover
overstates the average price of and rate of appreciation for rental
properties (lower than for owner-occupied properties).

The CGT estimates were produced by the consultancy BERL for the Office of the Leader of the Opposition in 2011.

This is based on average Australian CGT per dollar of GDP between 2000 and 2009 (the period for which we have data)
multiplied by Treasury’s projected nominal GDP for 2026 and by the ratio of the intended New Zealand CGT tax rate against
the average Australian CGT tax rate (15%/25%).

of the analytical basis for those revisions so our detailed comments above are

NZIER report -Capital gains tax 83. Impact on the farming sector
A CGT will raise the effective tax rate imposed on the farming sector. Exactly how
much it will rise is another matter.
Some of the impact will be factored into land prices – which will fall by as much as 7%
in the year the tax is introduced. This would reduce the apparent change in tax rate.
The effective tax rate and change in land value will both depend on whether the rate
of farm sales falls.
A large reduction in farm sales would mean a $2.4 billion decline in land values, a
1.4% change in tax rates, for a sum total additional crown revenue of $190 million
(0.4%).
3.1. At first glance tax rates would increase
by up to 25%
On the face of it, farmers could face a material impact from a CGT with a CGT
increasing tax rates from 28% to 34% - once the tax is at full effect and assuming no
offsetting change in other tax rates.14 This is an increase in tax rates of close to 25%.
This assessment is based on agricultural land worth an estimated $170 billion dollars
in 2011.15 A rate of appreciation of 3.75% p.a. used in Labour’s analysis of a GGT
implies this land will be worth $290 billion in 2026. With 1-in-20 farms traded each
year and a 15% CGT this implies an additional $940 million in tax – once the tax is at
full effect.16 This compares to an estimated $3.8 billion tax paid on projected
operating surpluses of $13.6 billion.
This increase in tax rates is larger than is likely to be experienced by other industries
because agriculture is capital intensive. Around three-quarters of value added in
agriculture is from capital (land and plant and equipment and machinery). This is
higher than the economy-wide average of around 50% although smaller than the
79% and 83% shares of value added found in the utilities and mining sectors.
3.2. Lower land prices mean lower tax
revenue
The importance of land to the farming sector also means that future capital gains tax
liabilities will be factored into prices which people are willing to pay for farms. Sector
wide, a 15% CGT would reduce the (present) value of projected cash-flows by $11.5
14
We focus on changes to taxes on capital income and assume farm profits are all taxed at the current corporate tax rate of
28%.
15
This is an estimate for 2011. This is used as the base year for our analysis for comparability with the Labour party’s analysis.
Different choices of base year would change the dollar values we use but does not alter the overall findings of our analysis
which is best assessed in terms of tax as a share of other numbers such as total tax revenue, land value or sector operating
surplus.
16
For sake of comparability we use the same appreciation assumption used in the Labour party’s analysis. We also follow the
assumption that the policy reaches full effect in 15 years.
NZIER report -Capital gains tax 9billion and this value would come off the current value of farm land.17 For those who
are looking to exit the industry – e.g. to retire – this cost would be immediate. If
nothing else changes, this amounts to a 7% reduction in land values.
This reduction in land values means that the CGT will raise $870 million instead of the
$940 million suggested above and considerably less than the $1.3 billion estimated
by Labour.
3.3. Falling farm sales further reduce fiscal
gain
Farm sales are likely to fall in response to the CGT. In the short term, some farmers
who are faced with a fall in land prices would hold onto their farms for longer – if
they can. Longer term, those who are faced with the prospect of capital gains tax will
be able to structure their affairs so as to reduce or delay tax liability.
International research suggests asset turnover can fall by more than 10% for every
10% increase in changes to capital gains taxes. Most of these studies focus on equity
investment and changes in existing tax rates – meaning that the precise magnitude of
changes to farm sales is difficult to estimate with much precision. Table 1 provides a
range of possible impacts based on international estimates. The range is from no
change, which provides an upper estimate on the magnitude of impact of a CGT, to
reduction in sales of 79%, which we deem to be an upper bound on likely impacts.
The responsiveness of taxable sales to the introduction of the tax is referred to as
‘elasticity of realisation’ – in the last row of Table 1.
Aside from simply delaying sale, there would be significant opportunities to avoid
taxable ‘realisation’ events by keeping assets in the family. The CGT tax proposed by
labour would not treat transfers to family members as events where capital gains are
assessed.
Note that as turnover falls tax payments fall. This means the tax impact on cashflow
gets smaller. This then reduces the impact of the tax on land values which further
reduces tax revenue. In the case of the lower bound impact land values fall by only
1%, effective tax rates increase by only 1.4% and crown tax revenues rise by only
0.2%.18
17
The present valued reduction in cashflow is the discounted sum of tax as it rises over time towards a notional $940 million in
2015 – not adjusted for changes in turnover and lower land prices.
18
There would be limited wider or indirect effects of a capital gains tax on the farming sector. The CGT tax would principally
affect personal asset holdings and small business sectors. Moreover, if the farming sector can reduce its exposure to the
CGT tax we would expect similar adaptation in other sectors. This means that the overall size and impact on the economy
and on sectors supplying farms will be limited.
The only potentially material impacts are from reduced returns to R&D. Capital gains on patents and other intellectual
property is within scope of the Labour party’s CGT. This means that, other things being equal, rates of return to R&D will fall
and supply of new technical knowledge could fall. This is more a risk than an impact as changes in the supply of new
knowledge will depend crucially on other policies, such as subsidies to R&D.

NZIER report -Capital gains tax 114. Not worth the effort
Labour’s proposed CGT would not be a good addition to New Zealand’s tax mix.
While the policy has some in-principle appeal, in practice it adds a degree of
complication to the tax system for which it is hard to see much in the way of benefit.
The way that CGT is both promoted and protested in the media it sounds like a game
change. It isn’t.
The CGT would do little to improve the efficiency and effectiveness of New Zealand’s
tax system. The main reason for this is that it would be riddled with exceptions,
unresolvable design problems and for all this it would raise very little revenue.
New Zealand could do with innovation and improvement in its tax system and
enlarging the tax base to include more capital income is an option but only if it raises
sufficient revenue to lower other tax rates.
A CGT as proposed by labour would raise very little revenue so it cannot be used to
materially improve the efficiency of the tax system. There is also currently no explicit
policy to use the revenue to reduce other tax rates.20
The CGT would have much less impact on the farm sector than might appear at first
glance. While the direct tax impact might look large – according to Labour party
estimates – the tax reduces sales of farms. This reduces taxable gains and lowers the
impact of the tax. This reduces revenue from the CGT – although current farm
owners will still see a decline in the value of their farms. The most likely outcome in
our view is the tax would raise a nominal $590 million in revenue (+0.5%) in 15 years’
time and reduce current land values by $7.6 billion (-5%).

In 2011 the Labour party said it would use revenue from a CGT to offset lower tax revenue from removing GST on fruit and
vegetables. This policy was dropped this year. This change of policy is good as it amounts to broadening the tax base with
one hand while narrowing it on another.
