Our tax system is totally stuffed. Here's how we can fix it

The Real Estate Institute has just launched yet another campaign against stamp duty. The Queensland government has just enacted a crafty new land tax which other states will follow. A High Court challenge against electric-vehicle taxing looms. Federal Labor is sticking doggedly to the Coalition's Stage 3 tax cuts which will pour billions into the wallets of rich, middle-aged men. And is sticking with other policies which do the same thing: negative gearing, cash rebates for franked share dividends, capital-gains tax concessions and superannuation tax immunity.

In the meantime, one of the worst taxes imaginable - payroll tax - continues its corrosive effect on employment. The second worst - stamp duty - cruels first-home buyers and people seeking to move to housing better suited to their needs. And income tax remains a tax for suckers who don't have lawyers and accountants to dodge it.

If ever there was a time not just for a wholesale review of federal and state taxes but to ensure the review is acted upon, this is it. Because budgets are in massive deficits in every jurisdiction.

I will turn first to Queenland's new land-tax arrangements which display astonishing yet simple lateral thinking simple and will enable the Queensland Treasury to rake its croupier across the property gambling table and drop lots of extra chips into the public purse.

Land tax is a hotch-potch. All the states and territories have different rules. All exempt the principal residence, except NSW, which taxes mega mcMansions even if they are principal residences.

All but the ACT have thresholds. In the ACT every investment property is taxed and the rate increases if the individual property's value goes beyond a certain level. The ACT has the highest land tax in Australia.

Most other jurisdictions take the total value of all of an individual's holding in that jurisdiction, which then determines the rate of tax. In NSW, the unimproved total value of one's NSW property has to be more than around $800,000 before the tax kicks in. In WA, $300,000 and so on. Only the Northern Territory has no land tax. The federal government had imposed land tax from 1910 to 1952 when foolishly it abolished it because it was seen to be unfair to farmers.

In Queensland, until this year, if your unimproved total property value was less than $600,000, you paid no tax.

Then Queensland got infected with a combination of cunning and self-righteousness and changed the rules, in a way never done before.

Why, they asked, should someone with less than $600,000 unimproved property in Queensland pay no tax if they were a rich property-owning tycoon in other states?

So, from next month Queensland residents who own one or more investment properties will have to add the value of their interstate properties when determining land-tax liability in Queensland.

MORE CRISPIN HULL:

So, someone who had a modest (under $600,000 unimproved value) bolt hole in sunny Queensland who used to pay no land tax will suddenly get a big land-tax bill if they happen to own investment property in other states and territories. Ouch!

What if all the other jurisdictions followed suit? Ouch times seven.

What if the feds chimed in? Another ouch.

As it happens, I will have to pay land tax in Queensland for the first time. Nonetheless, I think it is a fair scheme and other states should apply it, provided they do it in the way Queensland has done.

Queensland does a notional assessment on total Australian unimproved property value, for example, $100,000 of Queensland property and $900,000 of NSW property.

That would result in a notional tax bill of about $10,000, But Queensland only levels the tax on the Queensland portion of the notional bill. In our example that is $100,000 of $1,000,000 or 10 per cent. So, our notional tax bill is reduced to 10 per cent of $10,000 or a fairly reasonable $1000. Before the change it was zero.

In short, the capacity to pay and level of tax is determined by a person's total Australian property holding, but only applied to the holding in the individual state, in this case Queensland.

It seems complicated, but to achieve fairness and better economic outcomes, you often need complex systems.

One of the great beauties of land tax is that land values cannot be hidden. Land tax is far superior from an economic and social-justice perspective than stamp duty.

There have been a few half-hearted attempts to replace the one-off barnacle of stamp duty with annual land taxes, but stamp duty remains appallingly high in all jurisdictions. State revenues that depend on it are subject to wild revenue fluctuations as property markets yo-yo.

Consumption taxes like the GST are also hard to avoid. If the government must go ahead with the madly unfair Stage 3 tax cuts, it should at least broaden the GST to capture a lot of things that mostly the wealthy spend money on: private-school fees, private health and a raft of GST-exempt semi-medicines found in pharmacies.

It should also apply the GST to all rates and land tax, with compensation for middle- and low-income families.

It should cut tax deductibility for state charges on investment property (a justifiable chink against negative gearing). It should restrict cash rebates for franked dividends to what the taxpayer got the previous year, as was done with hospital and medical spending without any song or dance.

And something has to be done about road-charging before the avalanche of electric vehicles turns the flood of fuel taxes into a trickle.

There are lots of little tweaks that can make the tax system fairer and help with the bottom line without scaring the horses by shouting big-ticket items from the rooftops as Labor did in 2019. The Queensland land-tax changes show the way, even if it makes a few people like me say "ouch!"
