In this age of internationally mobile capital, we are repeatedly told that if we want to attract and retain investment, we must make our tax system more “competitive”. Very conveniently for the investors, competitive taxes are taken to mean low taxes, in which case governments must engage in a “race to the bottom” — competitively cutting taxes and public expenditure, sacrificing their schools, hospitals, transport systems and other essential services on the altar of global finance.

Fortunately this is bunk. In fact the attractiveness of the tax system to investors has more to do with the type of tax than with the amount of tax collected. “Taxes ain’t taxes!”

SPIN: The Family Home is exempt from land tax. (And all the people shall say: Amen.)

FACT: If home buyers don’t have to pay land tax, they can afford higher mortgage repayments, hence higher prices. While the price of a house is limited by the cost of construction and by competition among builders, a home is not just a house; it also includes land, which is a limited natural resource, and whose price is therefore determined by what people are willing and able to pay for it. So there is nothing to stop higher land prices from absorbing the entire benefit of the tax “exemption”, in which case the buyer still pays the tax — to the seller instead of the government!

Since the Howard government gained control of the Senate, we have been hearing numerous proposals for reducing the top marginal rate of income tax. The excuse is that high marginal rates reduce the incentive for wealth creation and encourage tax minimization. Let’s put this excuse to the test.

A holding tax is a tax of so many percent of the value of an asset per year, payable by the owner of the asset. If income tax were replaced by holding taxes, the top marginal rate of income tax would be zero. Beat that! And if those holding taxes were confined to assets that taxpayers can neither create nor destroy nor move out of the taxing jurisdiction — assets such as land and monopolies — the taxes would cause zero reduction in the stock of assets and zero discouragement to the production of new assets. That takes care of wealth creation.

In every marginal electorate, politicians promise to take revenue raised by nationwide or statewide taxes and spend it on projects that confer purely local economic benefits. This practice is corrupt and unnecessary — corrupt because a minority of taxpayers are bribed at the expense of the majority, and unnecessary because, if a project is economically justified, it can be funded out of the benefit that it confers — and, by implication, from within the area that gets the benefit.

If a project confers a benefit on a limited area, you can’t share in the benefit unless you live or do business in the area; and for that purpose you need access to real estate in the area. Therefore the market value of the benefit is manifested as uplifts in land values in the affected area. If the project satisfies a cost-benefit test, the total uplift will exceed the cost, so the project can be funded by clawing back only a fraction of the uplift through the tax system, leaving the rest of the uplift as an unearned windfall for owners of property in the affected area — and without burdening the taxpayers outside that area.

The flat tax fanatics are back. They say that if there were only one rate of income tax, the system would be simpler, and the rich couldn’t reduce their tax by converting one kind of income into another kind taxed at a lower rate. In the case of a pure flat tax — that is, a tax with one rate and no tax-free threshold — the tax rate could be lower, and the rich couldn’t claim multiple thresholds by splitting income between persons or between financial years.

But of course such reforms would make the tax system less progressive — a “progressive” tax being a tax that takes a higher fraction of income as income increases.
