An interesting opinion piece from Geoff Simmons, former Treasury economist and TOP Party leader ….

The real winners of Labour’s tax policy are the wealthy. This might seem counterintuitive, given its plan to raise the top tax rate on those who earn more than $180,000 to 39c in the dollar. Bear with me.

IRD data shows that half of New Zealand’s wealthiest people don’t even pay the top tax rate as it stands. They will be completely unaffected by this new tax rate. In fact, they are likely to benefit from it.

They are unaffected because they can use tax planning – trusts, family foundations and especially property investments – to reduce their taxable income. Labour’s change will worsen that problem, because it increases the gap between income tax rates and trust and company tax rates.

Which brings us to the second set of winners from Wednesday’s announcement: accountants and lawyers. Anyone who can help rich people set up ways to reduce their taxable income is set to board the gravy train.

We saw this the last time we had a 39c tax rate. Under the Clark-Cullen Labour government there was a surprising number of people who earned just below the threshold. This is a clear sign of people gaming the system.

Our tax system generally sticks to the good practice of taxing lots of things a little bit, so that it doesn’t distort behaviour. PAYE earners already pay their fair share of tax. By lifting the top rate far above the company and trust rate, Labour’s change will add a lot of complexity to the tax system without generating much revenue.

But the real winners from Labour’s policy are real estate agents and wealthy people themselves. That is because the tax change is likely to send property prices even higher.

The real problem with our tax system is the different tax treatment of property compared with other investments.

People with money in other forms of investments – KiwiSaver, bank deposits and businesses – pay some of the highest tax rates in the world on the returns from those investments. Meanwhile, property investments – especially the family home – pay some of the lowest taxes in the world.This provides a massive incentive to speculate on property. That is why we put more of our money into property than any other country in the world. That means we put less into businesses (which actually create jobs and exports) than any other country. This is also one reason why we have some of the most unaffordable housing in the world.

Increasing the top tax rate to 39c will make the problem worse. If someone is earning more than $180,000, they would now pay 39c in the dollar on dividends from shares, for example. Whereas they will pay no tax on the returns from owner-occupied property, and only half the returns from rental property. This is an even bigger incentive to pile into property investment.

Again, this happened last time we had a 39c top tax rate. Remember that house price boom in the 2000s? Westpac research suggests house prices rose 17 per cent simply due to that 39c top tax rate. That will happen again.

This is important because leveraged property investors determine house prices. So, perversely, Labour’s tax policy will push house prices even higher – further locking young people out of the market and enriching those who are already wealthy.

When combined with quantitative easing and the Reserve Bank dropping restrictions on loan-to-value ratios, the property market is guaranteed to roll ever upwards under Labour’s next term. New Zealand’s wealthiest citizens will be laughing all the way to the bank.

Let’s keep moving … to another rental.
