WA land tax calculator
Work out your WA land tax for the 2026-27 assessment year — charged on the aggregated unimproved value of the taxable land you owned at midnight 30 June 2026 — plus the metro region improvement tax if your land sits inside Perth.
Rates verified against the official sources — how we check.
Your tally
That's an effective 0.16% of your taxable land value, each year.
Estimate for standard holdings. Exemptions (home, primary production and others), joint ownership and grouping rules change the result — confirm with WA Government.
The scale hasn’t moved since 2015-16 — and that’s the catch.
WA’s thresholds are fixed by rate, not indexed: nil to $300,000, a flat $300 to $420,000, then marginal rates. Perth land values have climbed hard while the bands stood still, so holdings that owed a few hundred dollars a decade ago now sit several bands higher without the owner buying anything.
How Western Australia land tax works
WA assesses land tax on the aggregated unimproved value of all taxable land you owned at midnight 30 June — the value of the dirt alone, set by the Valuer-General, with your home and primary production land exempt. Unusually, WA runs a single scale for every kind of owner: no trust surcharge, no absentee loading, and (also unusually) no foreign surcharge on land tax at all.
The scale opens with a step rather than a rate: nothing to $300,000, then a flat $300 for values to $420,000, then marginal rates from 0.25% up to 2.67% past $11 million. Land inside the Perth metropolitan region also pays the metro region improvement tax — 0.14% of the value above $300,000 — which funds the region’s open space and road reserves. One protection worth knowing: the taxable value is capped at 150% of last year’s, so a wild revaluation can’t more than double-and-a-half your base in one hit.

Unchanged since 2015-16. Perth metro land adds MRIT: 0.14% of the value above $300,000.

Worked examples
- A $400,000 block in Bunbury: inside the flat band, so the bill is exactly $300 — the same as it was at $310,000 or $419,000.
- An investor with $800,000 of unimproved value: $300 + 0.25% × $380,000 = $1,250. If that land is in metro Perth, MRIT adds $700 for $1,950 all up.
- A portfolio at $2,000,000: $8,950 + 1.8% × $200,000 = $12,550 — the 1.8% band bites quickly once you pass $1.8m.
Land tax is one line of the annual holding picture — the negative gearing calculator shows the after-tax cost of the whole thing, since land tax is generally deductible against rent. Buying? The LMI calculator covers mortgage insurance over 80% LVR, and the CGT calculator covers the day you eventually sell.
