Middle New Zealand in the Firing Line of Green Tax Changes
The Green Party is promoting a new tax package it says will cut income tax for most New Zealanders by introducing a $10,000 tax-free threshold and reshaping the tax brackets. The difficulty for many clients is that the package also increases tax pressure on higher earners, property investors, and larger businesses, while broadening the range of situations in which gains and profits can be taxed more heavily.
For clients earning around $100,000 to $150,000, the PAYE position may improve modestly on paper. But once investment income, property sales, total income above $160,000, or business exposure are added to the mix, the policy becomes much less attractive.
PAYE changes
Under the Greens’ proposal, the first $10,000 of income would be tax-free and lower and middle income bands would be reshaped. At the same time, the marginal rate on income between $80,000 and $159,999 would rise from 33% to 33.5%, and a new 45% rate would apply to income over $160,000, compared with the current 39% rate over $180,000.
For someone on a steady salary between $100,000 and $150,000, the lower tax on the first slice of income may still produce a net saving. The weakness in the policy is that it becomes much harsher where income is not steady, especially where bonuses, shareholder salaries, business profits, or taxable property gains are added into the same tax year.
Comparative tax table
Income band | Current system | Proposed Green policy |
|---|---|---|
$0–$10,000 | Taxed from first dollar at 10.5% | 0% tax-free threshold |
$10,001–$19,999 | Mainly 10.5% | 10% |
$20,000–$39,999 | 17.5% | 17.5% |
$40,000–$59,999 | 17.5% / 30% crossover | 25.5% |
$60,000–$79,999 | 30% | 30.5% |
$80,000–$159,999 | 33% | 33.5% |
$160,000–$180,000 | 33% | 45% |
$180,001+ | 39% | 45% |
For incomes in the $100,000 to $150,000 range, the reshaped lower brackets are expected to outweigh the slight increase in the 33.5% band. Once income rises materially above $160,000, that benefit narrows quickly, and above $180,000 the proposal becomes clearly more expensive for some taxpayers.
Income above $180,000
A client earning $200,000 shows where the policy starts to bite.
Under the current tax scale, total income tax on $200,000 is about $57,077, while under the Green proposal it would be about $58,950, creating an extra annual tax cost of approximately $1,873.
That extra liability arises because the Green proposal applies the 45% top rate from $160,000 rather than the current 39% top rate from $180,000. In practical terms, the benefit of the lower tax on the bottom part of income is eventually overtaken by the earlier and steeper top rate.
Investment property owners
The bigger downside of the Green package is for clients with residential investment property. The party has said it would reverse the current Government’s landlord tax changes by removing interest deductibility for residential investment property and restoring the bright-line test period to 10 years.
That would have two direct effects:
Mortgage interest on residential rentals would no longer be deductible in calculating taxable rental income.
A sale of residential property within 10 years would be more likely to fall within the bright-line rules and result in a taxable gain.
This matters most for clients with one or two leveraged rentals, because they may be taxed on paper profits even when their real cash flow is under strain. Interest is often one of the largest holding costs, so removing deductibility can materially distort the true after-tax return.
Capital gains tax – or something close to it
The Greens have not announced a full, broad capital gains tax applying to all assets. New Zealand would still not have a general CGT in the way Australia does.
However, that does not mean property investors are unaffected. Instead, the Greens are proposing a tougher form of tax on gains through existing income tax rules by:
Restoring the bright-line period to 10 years.
Taxing gains on sale within that period as ordinary income.
Removing interest deductibility on residential rentals.
For many clients, that will feel very similar to a capital gains tax in practice. More sales will fall into a taxable window, and the gain will be taxed at full marginal tax rates rather than under a separate concessional CGT regime.
That is an important distinction from Australia. Australia generally taxes capital gains on investment property, but individuals and trusts may qualify for a 50% CGT discount on assets held for more than 12 months. The Green proposal offers no equivalent discount. Instead, if a gain is taxable, the full gain is added to income and taxed at normal marginal rates.
Property sale profits
The tax cost becomes much more significant when a rental property is sold for a profit. If a sale falls within the relevant bright-line period, the gain is generally treated as taxable income rather than a tax-free capital gain.
Under the Green proposal, restoring the bright-line period to 10 years means more sales would fall inside that taxable window. For a client already earning $100,000 to $150,000, a taxable gain on sale could push total annual income above $160,000, causing part of that gain to be taxed at 45%.
For example:
Salary income of $130,000
Bright-line gain on rental sale of $200,000
That produces total taxable income of $330,000. Under the Green proposal, all income above $160,000 would be taxed at 45%, so a large part of the property gain would be taxed at the new top rate.
Higher-income property example
The position is even more severe where the client is already earning above $180,000 before the property is sold.
For example, a client on $200,000 salary who also realises a taxable property gain of $150,000 would have total taxable income of $350,000.
Under current rules, income above $180,000 is taxed at 39%. Under the Green proposal, income above $160,000 is taxed at 45%, meaning the top slice of income in the year of sale is taxed much more heavily. That can lead to a substantial one-off tax bill at exactly the time the client may be repaying debt, exiting an investment, or reallocating capital.
Corporate tax changes
The Greens have also announced changes aimed at large corporates. At present, most New Zealand companies are taxed at 28%.
Under the new policy, the company tax rate would increase from 28% to 33% for big companies with annual turnover exceeding $30 million. The Greens say this would apply to roughly the largest 0.7% of companies, including large banks, major energy companies, and the supermarket duopoly.
For most small and medium privately owned companies, the 28% rate would remain unchanged. That means the typical closely held business is unlikely to be directly caught by the higher corporate rate.
Even so, the wider direction is clear. The Greens are prepared to impose more tax on larger business profits, and those costs may ultimately feed through into prices, borrowing costs, investment decisions, and business confidence.
The party has also proposed a bank levy and a withholding tax on large offshore tech profits, reinforcing the broader theme that larger institutions and capital are expected to bear more of the tax burden.
Why this matters
For many clients, the Green package offers a modest PAYE benefit but significantly worsens the tax treatment of residential investment property, increases the burden on higher incomes, and signals a more aggressive tax approach to capital and large business.
It increases the risk that ordinary investors are taxed at top marginal rates on property gains, while also reducing deductibility for one of their key holding costs. For business owners, even if their own company is not directly caught by the higher corporate rate, the policy points to a tax system moving further against investment, retained earnings, and capital accumulation.
In practical terms, the package may sound attractive at first glance, but it makes long-term property investment less stable, less predictable, and more heavily taxed. For clients with one or two rentals, higher incomes, or exposure to business and investment structures, the downside may be more significant than the initial income tax saving.
