You’ve bought your investment property. You’ve sorted your mortgage, your property manager, your insurance. And then, a few months later, a bill arrives from the state revenue office.
Land tax.
For many first-time investors, it comes as a surprise. For experienced investors building a portfolio, it’s one of the most important holding costs to plan around — because it compounds as your portfolio grows, and the rules are different in every state.
Here’s everything you need to know.
What Is Land Tax?
Land tax is an annual state-based tax on the unimproved value of land you own — essentially, the value of the land itself, excluding any buildings or structures on it.
It’s charged by state and territory governments (not the federal government), which means the rates, thresholds, and exemptions vary significantly depending on where your property is.
The key thing to understand: land tax applies to the land value, not the total property value. A $900,000 house might sit on land valued at $550,000 — and it’s that $550,000 that land tax is calculated on.
Who Has to Pay It?
Land tax applies to investors. Your primary place of residence (PPOR) is exempt in all states and territories — so if you only own the home you live in, land tax doesn’t affect you.
Once you own investment property, vacant land, or a holiday home (in most states), land tax becomes relevant. You’re taxed on the total value of all the taxable land you own in that state — your primary residence excluded.
This means: the more investment properties you accumulate in the same state, the more land value stacks up, and the higher your land tax bill gets.
How Is Land Tax Calculated?
Each state sets its own threshold — a minimum land value below which no land tax is owed. Once you exceed that threshold, tax is charged on the amount above it, typically on a sliding scale.
Here’s a rough overview of thresholds and rates by state as of 2026 (check your state revenue office for current figures — these change):
- New South Wales: Threshold $1,075,000. Rate: 1.6% on value above threshold, plus a base amount. Premium rate applies above $6,571,000.
- Victoria: Threshold $300,000 (general). Rate: 0.2%–2.65% on value above threshold depending on total land value. Surcharge applies for foreign owners.
- Queensland: Threshold $600,000. Rate: 1%–2.75% on value above threshold. Aggregated across all QLD properties you own.
- Western Australia: Threshold $300,000. Rate: 0.25%–2.67% depending on total value.
- South Australia: Threshold $534,000. Rate: 0.5%–2.4% on value above threshold.
- Tasmania: Threshold $100,000. Rate: 0.45%–1.5%.
- ACT: Land tax applies differently — it’s calculated on Average Unimproved Value and charged quarterly to landlords renting out residential property.
Note: these figures shift regularly. Your state revenue office website is the definitive source.
A Real Example: NSW Investor
Let’s say you own two investment properties in Sydney. The land value of each (as determined by the NSW Valuer General) is $600,000 and $550,000.
Combined land value: $1,150,000.
NSW threshold: $1,075,000.
Taxable land value: $1,150,000 − $1,075,000 = $75,000.
At 1.6% plus a base amount of approximately $100, your land tax bill would be around $1,300 for the year.
Now imagine a third Sydney property with a land value of $700,000 joins the portfolio:
Combined land value: $1,850,000.
Taxable land value: $1,850,000 − $1,075,000 = $775,000.
Land tax: $100 + (1.6% × $775,000) = $12,500/year.
That’s a meaningful annual holding cost — and it comes entirely from the portfolio growing, not from any change in the properties themselves.
The Portfolio Scaling Problem
Land tax gets expensive fast in high-value markets — which is exactly where most investors want to buy.
The reason: land values are aggregated within each state. Every investment property you own in the same state adds to your cumulative land value. As you cross into higher tax brackets, each new property attracts land tax at a higher marginal rate — not just on that property’s land value, but potentially on your whole taxable holding.
This is why many experienced investors deliberately diversify across states — buying one property in NSW, one in Queensland, one in Victoria — rather than concentrating their portfolio in one state. Each state has its own threshold, so spreading your properties keeps you in lower tax brackets across the board.
It’s not purely a tax strategy — location selection should still be driven by growth fundamentals — but understanding land tax early can influence where you choose to build.
Is Land Tax Deductible?
Yes. Land tax paid on investment properties is a tax-deductible expense in your annual tax return.
This softens the blow — if you’re in the 37% tax bracket, the ATO effectively covers 37 cents of every dollar of land tax you pay. But you’re still paying 63 cents in the dollar yourself, so it’s not a reason to ignore the cost.
Include land tax in your annual holding cost calculations alongside mortgage interest, property management fees, insurance, and maintenance. It’s a real cost that affects your cash flow position.
Common Exemptions and Concessions
Beyond the PPOR exemption, most states offer additional concessions worth checking:
- Primary production land: Land used for farming or primary production is often exempt or concessionally taxed.
- Charitable organisations: Land owned by registered charities is typically exempt.
- Retirement villages and aged care: Specific exemptions apply in most states.
- Land under construction: Some states allow exemptions or concessions while a property is being built and cannot be rented.
- Affordable housing / build-to-rent: Several states have introduced specific concessions to encourage affordable rental housing — worth checking if this applies to your investment type.
If you own property through a trust or company structure, different rules apply in most states — sometimes unfavourably (trusts often lose access to the tax-free threshold in NSW, for example). Always get specific advice if your ownership structure involves anything other than individual names.
Trusts and Land Tax: A Common Trap
Buying investment property in a discretionary trust (family trust) is common for asset protection and estate planning. But it comes with a land tax cost that catches many investors off guard.
In New South Wales, discretionary trusts don’t get the general threshold — they pay land tax from the first dollar of land value. In Victoria, trusts also face a surcharge in some circumstances.
This doesn’t make trust ownership a bad choice — but it needs to be factored into your analysis before you buy. The land tax cost of trust ownership over a 10–20 year holding period can add up to tens of thousands of dollars. Get advice from a property-savvy accountant or solicitor before choosing your ownership structure.
How to Find Out Your Land Tax Position
The process is straightforward:
- Get your land valuation. Each state’s valuer general publishes land values annually. Your council rates notice or the state revenue office portal will show the assessed land value of your property.
- Add up all taxable land you own in each state. Include investment properties, vacant land, and holiday homes. Exclude your PPOR.
- Compare to the state threshold. If your total is above the threshold, you’re liable for land tax.
- Register if required. In most states, you need to register for land tax yourself — the state revenue office won’t always find you automatically. NSW, VIC, and QLD have online portals for this.
If you don’t register and you’re liable, you’ll still owe the tax — plus potential interest and penalties. Don’t assume the system will contact you.
Land Tax vs Stamp Duty: What’s the Difference?
Two common points of confusion:
Stamp duty (also called transfer duty) is a one-off tax paid when you buy a property. It’s based on the purchase price and is paid at settlement.
Land tax is an annual tax on the ongoing value of land you own. It keeps coming every year for as long as you hold the property.
Both are state-based. Some states — the ACT most notably — have been shifting away from stamp duty towards higher ongoing land tax, arguing it’s a more efficient tax. It’s a direction other states may eventually follow, though most haven’t moved yet.
What This Means for Your Investment Strategy
Land tax is not a reason to avoid investing in property. But it’s a cost that must be modelled honestly — especially as your portfolio grows.
A few things to build into your planning:
- Include land tax in your holding cost spreadsheet from day one. Don’t treat it as a surprise — it’s predictable once you know the rules.
- Review your land values annually. If values have risen, your land tax bill may increase even if you haven’t bought anything new.
- Consider state diversification as a deliberate strategy when scaling beyond two or three properties.
- Get advice on ownership structure before you buy — especially if you’re considering trusts or companies.
- Factor it into your yield calculations. A 4.5% gross yield looks different when land tax adds another $3,000–$8,000/year to your holding costs.
Final Thoughts
Land tax is one of those costs that feels abstract until it lands in your letterbox. At one property, it might be zero or minimal. At three properties, it can be a significant annual expense. At five or more, it becomes a major planning consideration.
The investors who handle it best are the ones who understand it early — before they’ve accumulated properties in a single state and found themselves in an expensive bracket. Know the rules, model the costs, and make decisions with the full picture in front of you.
Land tax is an increasingly significant cost as you focus on building a property portfolio in Australia — understanding state thresholds early saves you surprises later.
