Land tax and Metropolitan Region Improvement Tax (MRIT)

Land tax is an annual tax on land and is a source of general revenue for the Government of Western Australia. It assists in the funding of such services as education, health, and law and order.  It is based on land owned on 30 June and is calculated on the unimproved value of the land which is determined by the Valuer-General.

Land tax applies to the total unimproved value of all land held by the same owners. For example, if you own two properties in WA valued at $250,000 each, land tax would be charged on the total aggregated value of $500,000.

A land tax liability may exist within the Indian Ocean Territories as if they were Western Australia. See details of the arrangement between Western Australia and the Commonwealth.

Metropolitan Region Improvement Tax

is a special purpose tax used by the WA Planning Commission 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. The metropolitan region is defined by the following local government districts:

Armadale Bassendean Bayswater Belmont Cambridge
Canning Claremont Cockburn Cottesloe East Fremantle
Fremantle Gosnells Joondalup Kalamunda Kwinana
Melville Mosman Park Mundaring Nedlands Peppermint Grove
Perth Rockingham Serpentine-Jarrahdale South Perth Stirling
Subiaco Swan Victoria Park Vincent Wanneroo


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. If land is not subject to land tax, it will not be liable for MRIT.

The current MRIT rate will apply unless a different rate is confirmed in the State Budget.

Please refer to our online calculator to calculate your land tax and MRIT liability.

Calculation of land tax

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. Since July 2009, any increase in an unimproved valuation of an individual land item has been capped to a maximum of 50 per cent of the previous year’s valuation. This helps to reduce the volatility and unpredictability of growth in individual land tax and MRIT bills from significant land value increases. 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.

The amount of land tax payable is calculated by applying the appropriate rate of tax to the aggregated taxable value of land in the same ownership. Use the online calculator to calculate your land tax liability.


For example, if you owned two taxable properties in WA with taxable values of $200,000 and $300,000 respectively, the tax is assessed on $500,000 at the rate shown in the table above.

Generally, only land owned by the same owners is aggregated. For example, land that is owned solely by you is not usually aggregated with land you own jointly with another person or with land that you have an interest in through a company or trust. In such circumstances, a separate assessment notice is issued.

IMPORTANT: If all the land you owned under the same ownership at 30 June 2019 is not shown on one assessment, please notify the Office of State Revenue before the due date shown on your Notice of Assessment.
