There’s a key principle of economics that’s not widely realised. Economists believe anything that looks like a duck and quacks like a duck must be a duck. Q: When is something that isn’t government spending still government spending? A: when it’s a tax break.
A government can impose taxes and spend the proceeds on achieving some objective – say, helping the retired with their living expenses – or it can achieve the same objective by charging those people less tax than they’d otherwise pay.
Whichever way the government chooses to do it, the effect on the budget balance is the same. And the effect on the people the government’s trying to help should be the same.
The only difference is that the two ways of assisting people appear on opposite sides of the budget. One adds to government spending while the other subtracts from government tax revenue. But, reason economists, this is a distinction without a difference. In principle, it doesn’t really matter.
Which is why economists have long sought to highlight the lack of difference between the two ways of assisting particular people or businesses by referring to special tax concessions as “tax expenditures”.
But though there may be no difference between the two in principle, in practice there’s an important difference. Government spending – on the age pension, for instance – is highly visible. It’s “salient” as psychologists and behavioural economists say.
By contrast, tax concessions – such as those applying to income that’s saved in a superannuation scheme, for instance – are much harder to see.
The practical consequence of this big difference in visibility is that actual government spending is examined carefully each year by the bureaucrats and by the Expenditure Review Committee of Cabinet, whereas all the spending on tax concessions tends to be ignored until someone decides to play around with a few of them.
This relative lack of attention paid to our many tax breaks prompted Treasury many years ago to begin estimating the value of the most important of them and publishing an annual Tax Expenditures Statement.
In 2019, however, the statement’s name was changed to the snappier, more enticing and informative Tax Benchmarks and Variations Statement. What a page-turner.
When the latest statement, for 2021, was published a few weeks ago, Dr John Hawkins, of the University of Canberra – in an earlier life, a senior Treasury official – used an article on the universities’ The Conversation website to explain that the name change reflects the truth that the amount of tax the government forgoes by granting a certain tax concession isn’t necessarily the same as the amount of tax it would regain if it abolished the concession.
Why not? Because when you make certain actions “tax-preferred”, people become more likely to take those actions, whereas when those actions cease to be tax-preferred people become less likely to take them.
But there’s another, less-defensible reason for switching to a title that will make tax expenditures even less visible than they already are. In the main, when governments want to help people in the bottom half of the distribution of incomes, they pay them money or buy things for them. But when governments want to help people in the top half of the distribution, they give them tax breaks.
(Hawkins points to one exception to that rule: the exemption of fresh food from the goods and services tax favours the poor over the rich because fresh food accounts for a higher proportion of the spending of the poor.)
If you’re well-off, and so have to pay proportionately more tax to support government spending to help those not doing as well as you are, it suits you for government spending to be highly visible and regularly scrutinised by politicians looking for ways to save money.
Conversely, it suits you for the support you get from the government to come in the form of tax concessions and thus be hidden from the public’s and the politicians’ view.
Hawkins notes that the biggest annual tax expenditures are: $64 billion because private homes are exempt from tax on any capital gain when they’re sold; $23 billion because the earnings on money in superannuation funds are taxed at a concessional rate; $21 billion because contributions to super funds are taxed at a concessional rate; and $12 billion because capital gains are taxed at only half the rate that income from “personal exertion” (work) is taxed.
Last financial year, the top 10 tax expenditures totalled just under $120 billion, which compares with total actual tax collections by the federal government of $460 billion. This year, 2021-22, the cost’s expected to be $150 billion. That increase of almost a quarter is explained mainly by the boom in house prices and share prices.
While tax expenditures primarily benefit the individual taxpayers who receive them, there’s a flow-on benefit to the industries conducting the economic activity that’s getting favourable tax treatment.
One stand-out is the property industry – developers, builders and real estate agents – which sees itself as benefiting from negative gearing and the 50 per cent discount on capital gains tax.
Another stand-out is the superannuation industry. It’s selling a product that’s heavily subsidised by the government – apart from the small fact that the government compels employers to buy its product on behalf of their employees.
The super industry has led claims that Treasury’s estimates of the value of tax expenditures are overstated. But Hawkins notes that its estimates of the revenue gained by canning a tax break don’t differ greatly from its estimates of revenue forgone.
A final “benefit” from the near invisibility of tax expenditures is that it allows recipients to delude themselves – and others – that they’re not dependent on government handouts.
John Roskam, boss of the Institute of Public Affairs, has written to correct my memory of an exchange between us more than a decade ago, as recounted in earlier editions of this column. I had written that the institute was “taxpayer-subsidised”. He wrote denying my claim. I replied that, since its donations were tax-deductible, this amounted to a subsidy from the taxpayer. He objected that I didn’t describe other government-supported organisations in this way.
