About land tax

Land tax is an annual tax on land not used as your principal place of residence. You will receive a notice of assessment for land you owned at midnight on 30 June.

We impose land tax based on the total unimproved value of all land held by the same owners. The unimproved value of the land is determined by the Valuer-General.

If you are liable to pay land tax, you may also be required to pay metropolitan region improvement tax.

Pay your land tax or find out if you are eligible for an exemption.

Calculation of land tax

Show more
Land tax and MRIT are calculated on the aggregated taxable value of all land held in the same ownership (excluding exempt land) at midnight on 30 June.

The taxable value for land is the lesser of the current unimproved value of the land or 150% of the previous year’s unimproved value.

We calculate the amount of land tax by applying the appropriate rate of tax to the aggregated taxable value of the land. For example, if you owned two properties in WA with taxable values of $200,000 and $300,000, we will combine these values and assess tax on $500,000.

Use the online calculator to calculate your land tax liability.

Generally, we only aggregate land owned by the same owners. For example, the value of land that is owned solely by you is not usually combined with the value of land you own jointly with another person or with land that you have an interest in through a company or trust.

Metropolitan region improvement tax

MRIT is imposed on property with a land tax liability at a rate of 0.14 cent for every dollar of the aggregated taxable value of the land in excess of $300,000.

MRIT is a special purpose tax used to finance the cost of providing land for roads, open spaces, parks and similar public facilities. It is payable in addition to land tax on property located in the metropolitan area. See a map of the metropolitan region.

Contact us to formally advise us of the management of a property.

Use the land tax enquiry and select the subcategory 'Managing Agent'.

Attach a copy of the management authority to each request.

You will receive an email confirming that your information has been received and another email once your address details have been updated.

You can see the single ownership figure by inserting the unimproved valuation of the land and the relevant assessment year into the land tax calculator.

If a taxpayer owns more than one taxable property and you are not the managing agent for all of those landholdings, provide a signed letter from the owners confirming that you have been appointed as their managing agent for the specific landholdings. The letter must also authorise the Office of State Revenue to send all future land tax notices for that land and any other land held in the same ownership directly to your office.
