calx.io/WA Land Tax Calculator
Calculate annual Western Australian land tax for 2026-27, including the metropolitan region improvement tax for Perth metro land.
Use the land (site) value from your valuation or assessment notice, not the property price. Add together the land values of every taxable property you own in this state. Your own home is generally exempt.
Estimates only, not financial or legal advice. Land tax rates, thresholds, exemptions, and aggregation and grouping rules change and vary with individual circumstances. Always confirm with the relevant state revenue office before relying on a figure.
Frequently asked questions
How is land tax calculated in WA?
WA land tax starts as a flat $300 once your aggregated unimproved land value passes $300,000, then climbs from 0.25% to 2.67% above $11 million. All land you own at midnight 30 June is aggregated before the scale is applied. The same scale applies to individuals, companies and trusts.
What is the metropolitan region improvement tax?
Land in the Perth metropolitan region also pays MRIT of 0.14% of the value above $300,000, collected with land tax to fund regional infrastructure. The calculator has a metro toggle that adds it.
Is my home exempt from WA land tax, and do foreign owners pay more?
Your principal place of residence is exempt. WA has no foreign owner land tax surcharge; its 7% foreign surcharge applies to transfer duty at purchase only.
