Land tax is one of the costs that catches property investors by surprise, especially first-time investors and those starting to build a portfolio. It does not apply to your home. It does not show up when you buy. And the threshold works differently depending on which state your property is in.

Here is a plain-English explanation of how land tax works in Australia, what the current thresholds are by state, and what you need to think about as your portfolio grows.

What is land tax?

Land tax is an annual state government tax on the unimproved value of land you own. That means it is based on the land value only, not the house or improvements on top of it. Each state has its own rules, thresholds, and rates.

Importantly, land tax generally does not apply to your principal place of residence. The home you live in is typically exempt. It applies to investment properties, holiday homes, and land you own but do not live in.

Most states calculate land tax based on the total value of all taxable land you own within that state, not each property individually. That is a detail worth understanding before you buy a second or third investment property.

How the threshold and aggregation work

Each state sets a tax-free threshold. If your total taxable land value in that state falls below the threshold, no land tax is payable. Once you cross it, tax applies to the amount above the threshold at the applicable rate.

Here is where investors can be caught out. Because the threshold applies to the combined land value of all your properties in that state, adding a second or third property can push your total above the threshold even if each individual property seems modest.

For example, if three investment properties each have a land value of $400,000 in New South Wales, each one alone would sit below the threshold. But combined, they total $1,200,000, which puts you $125,000 above the NSW threshold. You now owe land tax on that $125,000.

Thresholds by state (2026)

Land tax rules differ significantly across Australia. Here is a general overview of how each state sits:

  • New South Wales: General threshold of $1,075,000. One of the higher thresholds nationally, but once you cross it the rates increase steeply. Trusts receive no threshold in NSW, so land tax applies from the first dollar of land value for trust-held property.
  • Victoria: Threshold of just $50,000, meaning almost every investment property in Victoria attracts land tax. Victoria also applies a temporary COVID-19 debt surcharge running through to 2033, adding to the annual cost.
  • Queensland: Individual threshold of $750,000. This drops to $350,000 for trusts and companies, which is an important consideration if you are thinking about holding Queensland property in a trust structure.
  • Western Australia: Threshold of $300,000 with a low starting rate of 0.25%. The cost on a single investment property with modest land value is often a few hundred to a couple of thousand dollars per year.
  • South Australia: Threshold of $783,000. Above that, the rate starts at 0.50% and rises progressively.
  • Tasmania: Low threshold of $87,000, making it relevant for almost all investment properties in the state.
  • Northern Territory: The only jurisdiction in Australia with no land tax. This is worth noting if you are comparing investment locations.

These thresholds and rates are reviewed periodically. Always check the relevant state revenue office for the most current figures before making a decision.

What land tax means for your cash flow

Land tax is an annual cost, and it needs to be factored into your cash flow projections when you are assessing whether an investment property stacks up. Many investors run the numbers on a property without including land tax, especially if their current portfolio sits below the threshold. But as the portfolio grows, land tax can become a meaningful expense.

When you are modelling the return on a new investment property, include land tax from the start. Ask: will this property push my total land value above the threshold? What does that mean for my annual holding costs?

Your accountant or a property tax specialist is the right person to help you calculate your current and projected land tax liability based on your portfolio and the states you are investing in.

How ownership structure affects land tax

The structure you use to hold investment property can significantly affect your land tax exposure, particularly in NSW and Queensland where trusts receive less favourable treatment.

This is one of the reasons why the structure conversation matters before you buy. Choosing to hold a property in a trust without understanding the land tax implications can result in a larger annual tax bill than holding in your personal name.

If you are considering investing across multiple states, each state operates independently for land tax purposes. You are assessed separately in each jurisdiction, which can work in your favour if you are building a geographically diversified portfolio.

Getting the full picture before you invest

Land tax is just one part of the total cost of holding an investment property. Mortgage repayments, council rates, insurance, maintenance, property management fees, and potential vacancy also need to go into the numbers.
