Compare Land Tax Across States
Land holdings in this value range
At $5 million and above, you are in the premium or top rate brackets in all states. Annual land tax can exceed $100,000-$300,000. At this level, land tax is a material drag on investment returns and often becomes the largest recurring government cost on the portfolio. Foreign ownership at this value adds six figures in surcharges. Active portfolio management — including state diversification, structure optimisation, and periodic review of land valuations — is standard practice.
Challenge land valuations
Land valuations are issued by state Valuer Generals and can be objected to. At $5M+ total land value, a 5% reduction in assessed value saves thousands in annual land tax. Lodge objections within 60 days of receiving your land valuation notice. Professional valuers can support your case.
Land tax vs stamp duty trade-off
The ACT's shift from stamp duty to ongoing land tax illustrates a broader policy trend. For large portfolios with infrequent transactions, stamp duty (paid once) may be preferable to high annual land tax. For active investors who buy and sell frequently, lower stamp duty and higher land tax (like the ACT model) reduces transaction friction.
Typical owners: High-net-worth individuals, property syndicates, developers holding land banks, institutional investors, and large family offices with diversified property portfolios.
