About the Land Tax Western Australia Calculator
A land tax Western Australia calculator helps property owners estimate the annual land tax payable on investment properties and commercial land in WA. Administered by the Department of Finance (RevenueWA), land tax in Western Australia is calculated on the total unimproved value of land holdings. Understanding your WA land tax liability is essential for accurate property budgeting.
What is the Land Tax Western Australia Calculator?
This calculator estimates the land tax payable to RevenueWA for the current financial year. Land tax in Western Australia applies to all taxable land you own as at 30 June each year, excluding your principal place of residence. WA uses a progressive tax scale with a tax-free threshold of $300,000 for general landholders and $300,000 for special arrangements. The rates for 2025-26 range from 0.15% for land valued between $300,000 and $420,000 up to 2.5% for land valued over $11,000,000. The calculator inputs the total unimproved value of your WA land holdings, exempts your main residence, and applies the appropriate marginal rate. It also accounts for any joint ownership or trust holdings, as different thresholds may apply. The tool provides a clear breakdown of the tax-free amount, the taxable value in each bracket, and the total land tax payable. WA property investors use this calculator to plan for their annual tax obligations and compare the land tax burden with other states such as VIC and NSW.

Worked Australian Example
Practical Example
Jennifer owns two investment properties in Western Australia: a unit in Fremantle valued at $350,000 (land component $180,000) and a house in Mandurah valued at $520,000 (land component $280,000). Her total unimproved land value is $460,000. She lives in a separate home in Subiaco which is exempt as her main residence. Using the calculator, Jennifer enters $460,000 as total unimproved land value, selects individual ownership, and confirms no trust or exempt land. The calculator applies the $300,000 threshold, leaving $160,000 in taxable land value. The land tax is calculated as $250 plus 0.15% on the amount between $300,000 and $420,000, and 0.55% on the amount between $420,000 and $460,000. Her land tax is $250 plus $180 (0.15% of $120,000) plus $220 (0.55% of $40,000), totalling $650 for the year. Jennifer budgets this amount into her property holding costs and notes that WA land tax is significantly lower than the equivalent land tax on similar values in Victoria.
How Our Land Tax Western Australia Calculator Works
Western Australian land tax is an annual tax on the **unimproved value** of taxable land you own in WA, assessed by RevenueWA on a progressive scale: 1. **Use the unimproved (land-only) value** — WA land tax is based on the land's value excluding buildings and improvements, as valued by the Valuer-General, not the market price of the house on it. 2. **Aggregate your WA landholdings** — the taxable values of all your WA land (except exempt land like your home) are combined, then assessed together. 3. **Apply the threshold and brackets** — below the tax-free threshold no land tax is due; above it, progressively higher marginal rates apply to the value in each band. **Land tax = fixed bracket amount + (marginal rate × aggregated value above the threshold).** Because it uses *unimproved* value and aggregates holdings, WA land tax can differ markedly from what a property's sale price would suggest, and adding land raises the tax across your whole WA portfolio. Your principal place of residence is generally exempt, and residential versus commercial use can affect exemptions. Thresholds and rates are set by RevenueWA and change, so treat the output as an estimate and confirm current figures.
When to Use This Calculator
Use this if you hold or plan to buy investment land in Western Australia. **Before purchasing additional WA land**, to see how aggregation and the unimproved-value basis affect land tax across your holdings. **At assessment time**, to check RevenueWA's figure and budget the annual cost. **When distinguishing land value from property price**, since WA taxes the unimproved value — useful for understanding why the bill may look different from what you expect. **When reviewing exemptions**, to confirm your principal residence is excluded and how residential versus commercial use applies. It suits WA property investors and advisers. Because the tax rests on aggregated unimproved values and excludes your home, confirm current thresholds and rates with RevenueWA before relying on the estimate.
