Land tax on investment property is one of the most expensive and least understood holding costs in an Australian property portfolio. Unlike stamp duty, which you pay once, land tax arrives every single year - and if you own properties across multiple states, the bills can stack up fast. In over 20 years as a mortgage broker on Sydney's Northern Beaches, I've watched investors be genuinely blindsided by this tax, often because they never factored it into their numbers when they bought. The good news is that with some planning, interstate property investors can legally and significantly reduce their land tax exposure - without compromising on investment quality.
Before I go further: this article provides general information only and does not constitute financial or tax advice. Land tax laws are complex, differ between states, and change regularly. Always seek independent advice from a qualified accountant or tax advisor before making any decisions based on land tax considerations.
Why Land Tax Hits Harder When You Concentrate in One State
Land tax is an annual state government tax calculated on the unimproved value of investment land you own. Crucially, each state aggregates all your taxable land within its borders and taxes the combined total - so owning three properties in NSW or Victoria means their land values are added together before the rates are applied. This aggregation is what accelerates your exposure as your portfolio grows.
What most investors don't realise early enough is that interstate properties are assessed completely separately. A property in NSW and a property in Queensland are each only assessed against their own state's threshold and rates - they don't affect each other. That's the structural opportunity at the heart of any interstate land tax strategy.
The thresholds vary dramatically between states. In NSW, individuals aren't taxed until their combined land value hits $1,075,000 - the highest general threshold on the eastern seaboard. Victoria, by contrast, has the lowest threshold in Australia at just $50,000, meaning virtually every investment property in the state attracts land tax. Queensland sits at $600,000 for individuals. The Northern Territory is the only jurisdiction in Australia with no land tax at all.
The Numbers: What Interstate Diversification Actually Saves You
Let me walk through a practical example. An investor with $2 million in combined land value held entirely in NSW faces a land tax bill of approximately $14,900 per year - calculated as the taxable value above the $1,075,000 threshold (roughly $925,000), multiplied by the 1.6% rate, plus the $100 base charge.
Now split that same $2 million equally between NSW and Queensland. The NSW holding ($1,000,000) falls below the $1,075,000 threshold - zero land tax. The Queensland holding ($1,000,000) is above Queensland's $600,000 individual threshold and would attract approximately $5,500 per year. Total annual land tax: around $5,500 - a saving of roughly $9,400 compared to concentrating everything in NSW. At higher portfolio values, the savings compound significantly.
For Sydney and Northern Beaches investors in particular, this matters a lot. Sydney's strong capital growth means the land component of local investment properties has risen sharply over recent years, pushing more NSW investors above the threshold. Leveraging that Sydney equity to fund interstate acquisitions - in Brisbane, Perth, or Adelaide - is a strategy I discuss regularly with clients who want to grow their portfolios without the land tax bill growing at the same rate.
Land Tax Thresholds by State: What You Need to Know in 2026
NSW has frozen its general threshold at $1,075,000 from 1 January 2025, with no annual indexation until at least a government review in mid-2027. Given that Sydney land values are still rising in many areas, more NSW investors will gradually cross into taxable territory over time - without buying a single additional property. The premium threshold sits at $6,571,000.
Victoria made a dramatic change from 1 January 2024, cutting its individual threshold from $300,000 down to just $50,000. This swept approximately 360,000 additional Victorian landowners into the land tax system overnight. Victoria also carries a COVID-19 Debt Temporary Surcharge on top of standard rates, running from 2024 through to 2033. If you own investment property in Victoria, you are almost certainly paying land tax - and more than you would in any other state.
Queensland's individual threshold is $600,000, assessed as at 30 June each year, with assessment notices typically issued between August and October. For trusts and companies the threshold drops to $350,000. One important history note for interstate investors: Queensland proposed aggregating interstate land values for its land tax calculation in 2022, but abandoned the policy in 2023 following strong industry opposition. Queensland now assesses only Queensland land.
For an investor with $500,000 in taxable land value, no land tax is payable in NSW, Queensland, South Australia, or the Northern Territory. The same investor would face approximately $1,950 in Victoria, over $1,700 in Tasmania, and over $6,000 in the ACT. These differences are why your choice of states matters to the long-term economics of a portfolio. I always recommend checking directly with each state's revenue office for current rates - they change, and the specifics matter when you're making real decisions.
Building a Multi-State Portfolio: Practical Strategy
The most effective interstate land tax strategy starts before you buy, not after. Once you understand your target portfolio size, you can map out which states make sense from both an investment fundamentals perspective and a land tax efficiency perspective. For a Sydney-based investor targeting a $3–4 million portfolio, splitting holdings across NSW, Queensland, and Western Australia is a common approach - each state threshold provides a buffer before tax kicks in, while exposure to different property markets also reduces concentration risk.
Perth, Brisbane, and Adelaide have delivered strong growth and higher rental yields than Sydney in recent years, making them genuinely attractive on investment fundamentals, not just tax grounds. That's important - a property with low land tax is no consolation if the underlying investment doesn't perform. The land tax saving should be the bonus, not the reason you buy.
From a finance perspective, interstate expansion works best when it's structured carefully. Lenders assess interstate investment portfolios differently, and using equity in your Sydney or Northern Beaches home to fund interstate purchases requires a clear understanding of your total borrowing capacity across your whole portfolio. A well-structured investment loan strategy will account for the ongoing holding costs - including land tax - in the serviceability modelling, so you're not caught short when those annual bills land.
Ownership Structure and Land Tax: Get This Right Before You Buy
How you hold the property has a major impact on land tax - and the rules differ meaningfully between states. In NSW, special and discretionary trusts receive no general tax-free threshold at all and are assessed from $0. In Victoria, trusts face a lower threshold of $25,000 with a surcharge rate applied. In Queensland, trusts and companies are assessed from $350,000 rather than the individual threshold of $600,000.
The interaction of trust structures across multiple states is genuinely complex. What's efficient in one state may create a worse outcome in another. Investors who set up a family trust for asset protection reasons - often sensible from an estate planning standpoint - can find themselves paying significantly more land tax across their portfolio than they would in individual names. This isn't a reason to avoid trusts, but it is a reason to model the land tax implications for every state you invest in before you commit to a structure.
This is one area where the cost of getting proper professional advice upfront almost always pays for itself many times over.
Cash Flow, Deductibility, and Timing
Land tax on investment property is generally deductible against rental income, which helps offset the cost. For an investor on the top marginal tax rate, a $5,000 land tax bill might result in a $2,350 tax saving - but that still leaves $2,650 coming out of pocket each year. Run the full numbers on your investment cash flow with land tax included from the start.
Assessment timing differs between states and matters for cash flow planning. NSW issues assessment notices from January each year. Victoria assesses land held at 31 December, with notices issued early in the following year. Queensland assesses as at 30 June, with notices typically arriving between August and October. If you hold properties in multiple states, you'll have land tax bills landing at different times throughout the year - building this into your cash reserve planning avoids unpleasant surprises.
The Risks of Getting It Wrong
The most common mistake I see is investors building up a significant multi-property portfolio in one state - often their home state - without ever modelling the compounding land tax liability. By the time the bills are meaningful, selling or restructuring the portfolio triggers stamp duty and potentially capital gains tax implications that make any restructure expensive.
The second most common mistake is choosing an ownership structure without understanding how it interacts with land tax across every state in the portfolio. The savings from asset protection or other trust benefits can be partially or fully offset by higher land tax bills that weren't factored in at the outset.
Land tax rules can and do change significantly - Victoria's threshold reduction from $300,000 to $50,000 in 2024, and Queensland's abandoned interstate aggregation proposal in 2022–23, both show how quickly the landscape can shift. Any strategy built on current rules needs to be reviewed regularly, ideally as part of an annual meeting with your accountant.
