In most states, your principal place of residence is exempt from land tax. Investment and secondary properties are generally taxable.

Do thresholds change each year?

States review thresholds and rates periodically, often annually. Always check current thresholds for the relevant year.

How do companies and trusts differ?

Companies and trusts are not interchangeable. Victoria and South Australia apply separate trust schedules, while NSW special trusts receive no tax-free threshold. Some trust types qualify for general rates, so confirm the trust classification before relying on the estimate.

Why can South Australian land above the threshold still show no tax?

RevenueSA says no assessment is issued where the calculated total is under $20. For 2026-27 general-rate ownership, this creates a short range above the $936,000 threshold where the payable estimate remains zero.

Is land tax deductible?

For investment properties, land tax is generally deductible against rental income. Seek professional tax advice for your circumstances.

Land Tax by State Comparison

Important assumption

This estimate applies published land-tax brackets to the taxable land value entered. It does not calculate foreign-owner surcharge land tax, Victorian absentee-owner surcharge, WA Metropolitan Region Improvement Tax, vacant residential land tax, settlement adjustments, exemptions or concessional land classes.

The state bars are not like-for-like liabilities. Valuation dates, aggregation rules and ownership definitions differ. ACT uses each property's five-year average unimproved value and has separate unit-title apportionment, so do not compare its bar with an aggregate holding value entered for another state.

Check the relevant revenue office before relying on an estimate: Revenue NSW, SRO Victoria, Queensland Revenue Office, RevenueWA, RevenueSA and ACT Revenue Office.
