Land Tax Calculator for Australian Property Investors

Land tax is an annual tax charged by each state and territory on the land you own, based on its unimproved value, meaning the value of the land itself without the house or other buildings on it. It is assessed once a year on the total taxable land you hold in that state, not property by property.

Your home is generally exempt. Land tax usually falls on investment properties, holiday homes, vacant land and commercial property. Because it is an ongoing holding cost rather than a one-off, it eats into your rental return every year you own the property, so it is worth factoring in before you buy.

There is no national land tax. Each state and territory sets its own tax-free threshold and its own sliding scale of rates, and the tax is progressive, so a higher land value is charged at a higher rate. That is why the same parcel of land can attract very different tax depending on the border it sits inside.

The thresholds vary widely. New South Wales gives individuals a high general threshold, while Victoria's threshold is much lower, so Victorian investors tend to start paying on more modest holdings. The Northern Territory has no land tax, and the ACT charges from the first dollar. Switch states in the calculator to see how much the location alone changes the figure.

Land tax is assessed on the combined value of all the taxable land you own in a single state, a process called aggregation. As you buy more property in the same state, the total land value climbs into higher brackets, so your land tax can rise faster than you might expect from each property on its own.

This is one reason some investors spread holdings across different states or consider different ownership structures, since each state assesses your land separately. Structures have their own costs and tax consequences, so this is a question for a qualified accountant rather than a calculator, but it helps to understand why the bill grows the way it does.

Land tax is a deductible expense on an income-producing property, so you can generally claim it against your rental income, which softens the blow at tax time. It still reduces your net return, though, because the deduction only refunds part of the cost at your marginal rate, not the whole amount.

Treat land tax as one of the recurring holding costs alongside council rates, insurance, management fees and loan interest when you work out whether a property pays its way. A property that looks positively geared on rent alone can tip into a shortfall once land tax is added, so it belongs in your numbers from the start.
