WA land tax calculator

Your WA land tax for 2026-27 from the total unimproved value of your taxable land, with Perth’s metro region tax.

FY 2026-27 rates · verified against the official sources.

The combined unimproved value of all your taxable WA land at 30 June (from Landgate, not market prices) — your home and any primary production land are exempt and don’t count.

Where is the land?

Land on both sides of the boundary? This applies one answer to all the land entered; how MRIT treats a split holding is not modelled here, so ask RevenueWA.

Western Australia adds all your taxable land together before the threshold, so the values are summed.

The scale hasn’t moved since 2015-16 — and that’s the catch.

WA’s bands have stood still since 2015-16: nil to $300,000, a flat $300 to $420,000, then marginal rates. When land values rise and the bands do not, the same holding is taxed further up the scale without the owner buying anything.

How Western Australia land tax works

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.

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. One protection worth knowing: the taxable value is capped at 150% of last year’s, so a sharp revaluation can raise it by at most 50% in one year.

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.

Frequently asked questions

What is the land tax threshold in WA?
Land tax starts once your aggregated unimproved value exceeds $300,000 — but the first taxed band is a flat $300, not a percentage: $300,001 to $420,000 all pay exactly $300. Marginal rates only begin above $420,000. The scale has been unchanged since 2015-16.
How is land tax calculated in WA?
Add up the unimproved values of all your taxable WA land at 30 June, then apply the scale: nil to $300,000; $300 flat to $420,000; $300 + 0.25% of the excess to $1m; $1,750 + 0.9% to $1.8m; $8,950 + 1.8% to $5m; $66,550 + 2% to $11m; then $186,550 + 2.67%. Example: $800,000 costs $300 + 0.25% × $380,000 = $1,250.
What is the metropolitan region improvement tax (MRIT)?
An extra 0.14% of the value above $300,000 for land that is both liable for land tax and inside the Perth metropolitan region. On $800,000 of metro land it adds $700 to a $1,250 land tax bill. Land outside the metropolitan region never pays it.
Does WA have a foreign owner or trust surcharge?
No — WA is the outlier. There is no foreign surcharge on land tax and no separate trust scale: individuals, companies and trusts all pay the same rates. (Foreign buyers do pay a 7% duty surcharge when purchasing residential property, but that’s stamp duty, not land tax.)
Is my home exempt from WA land tax?
Yes — land you own and use as your principal place of residence at 30 June is exempt, whatever it’s worth, and primary production land is too. Land tax lands on rentals, holiday homes, commercial property and vacant blocks.
What is the 150% valuation cap?
The taxable value is the lesser of the current unimproved value and 150% of the previous year’s. Say a block valued at $400,000 last year is revalued to $700,000: it is taxed on $600,000 this year, not $700,000.
