Western Australia Land Tax: 2026 Rates & Thresholds Explained

Western Australia Land Tax: 2026 Rates & Thresholds Explained

Western Australia land tax is levied on the unimproved value of land (not including buildings). It applies to investment properties and vacant land above certain thresholds. Your principal place of residence (PPOR) is exempt. Unlike Victoria, WA does not have separate residential vs commercial land tax rates—the same progressive scale applies to all non-exempt land. This calculator estimates your WA land tax for 2025-26 based on the latest thresholds from the Department of Finance.

WA Land Tax Thresholds and Rates (2025-26)

Land tax in WA is progressive. The total tax is the sum of base amounts plus percentages on the excess within each tier. The thresholds below are for the taxable value (unimproved land value):

Residential vs Commercial Land in WA

WA does not differentiate land tax rates based on land use classification. Whether the land is residential, commercial, industrial, or agricultural, the same progressive scale applies to the unimproved value. However, there are important differences in how land is valued and what exemptions may apply:

• Residential land: Usually has a lower unimproved value per square meter than commercial CBD land. The land value assessment by the Valuer-General determines your tax. Improvements (the building) are excluded from the land value calculation.
• Commercial land: Often has higher unimproved values, especially in prime locations like Perth CBD, Fremantle, or major towns. This pushes owners into higher tax brackets more easily. Commercial land tax can be a significant holding cost.
• Mixed-use properties: If a property has both residential and commercial components, the land is typically valued as a single parcel. You may need to apportion if part is exempt (PPOR) and part is commercial.
• Rural/agricultural land: May qualify for different valuation methods or concessions. Check with the Department of Finance for specific farm land exemptions.

Primary Place of Residence (PPOR) Exemption

Your principal place of residence is completely exempt from WA land tax, regardless of land value. To claim the exemption:

• You must occupy the property as your main home for at least 6 months of the year (with some exceptions for temporary absences).
• You must be an Australian resident for tax purposes (citizen, permanent resident, or certain visa holders).
• The land must be used primarily for residential accommodation (e.g., a house, unit, or apartment).
• If you own multiple properties, only one can be designated as your PPOR. The others are subject to land tax if above threshold.
• You need to apply for the exemption through the Department of Finance or indicate it in your land tax assessment notice.

The PPOR exemption is valuable. A $1,000,000 residential property in Perth could otherwise owe around $6,600 + 1.75% on the next portion—totaling ~$15,000–$20,000 depending on exact value. Keeping it as your main home eliminates this cost entirely.

Example Calculation

Let's calculate WA land tax for an investment property with an unimproved land value of $1,500,000:

• Tier 1 ($0–$300k): $0
• Tier 2 ($300k–$1M): $300 + (0.9% × $700,000) = $300 + $6,300 = $6,600
• Tier 3 ($1M–$1.5M): $6,600 + (1.75% × $500,000) = $6,600 + $8,750 = $15,350
• Total WA Land Tax = $15,350
• Effective average rate: $15,350 ÷ $1,500,000 = ~1.02%

Frequently Asked Questions

Q1: Does WA land tax include the value of my house?

No. WA land tax is based on the unimproved land value (site value), which excludes the value of any buildings or improvements. The Valuer-General determines this value separately from the total property value you might see on a real estate listing (which includes the dwelling). For a typical house, the land value might be 20–40% of the total property value depending on location and dwelling condition. However, vacant land is taxed on its full unimproved value.

Q2: How often is land tax paid in WA?

Land tax is an annual assessment. The Department of Finance issues assessment notices each year (usually around June–July) for the upcoming financial year. Payment is typically due within 35 days of the assessment date, unless you elect to pay by instalments (four quarterly payments). You can also set up a direct debit or BPAY.

Q3: Can I appeal my land valuation?

Yes. If you believe the Valuer-General's land valuation is too high, you can lodge an objection with the Department of Finance within 60 days of the assessment notice. You'll need to provide evidence (recent sales of comparable vacant land, independent valuation, etc.). Many objections succeed in reducing the land value, which lowers your tax. However, the process can take months, and you must pay the tax based on the current assessment while awaiting the outcome (refundable if successful).

Q4: Are there any other exemptions besides PPOR?

Yes. WA provides land tax exemptions for:

• Charitable institutions (hospitals, schools, churches) used for charitable purposes.
• Public hospitals and certain health services.
• Native title lands held for the benefit of Aboriginal people.
• Mining tenements (subject to specific conditions).
• Land used for primary production (farm land) may qualify for a concession or exemption if it meets certain criteria (e.g.,持续使用, size thresholds).

Each exemption has specific eligibility criteria. If you think you qualify, apply to the Department of Finance with supporting documentation.
