How Rates Are Calculated

In the simplest terms, your rates are determined by multiplying a property’s valuation by a “rate in the dollar” that is set by the Shire Council. The formula is:

Property Valuation × Rate in the Dollar = Your Rates

 

Property Valuation

For most residents, your property is valued using one of two methods, which are determined by Landgate:

  • Gross Rental Value (GRV) The GRV represents the estimated gross annual rental income a property could reasonably earn. This value is used predominantly for townsite properties and is calculated regardless of whether the property is rented or owner-occupied. For non-residential properties, GST is also included. Vacant land is given a notional GRV equal to 3% of its Unimproved Value. New GRV valuations are made periodically, every 3 to 6 years.
  • Unimproved Value (UV) The UV is the value of the land only. It does not include the value of your house, other structures, or any improvements. This method is used for rural properties. For land within townsites, the UV does include merged improvements such as drainage, levelling, and filling. UV valuations are updated annually.

The 2025 Revaluation and how it affects Your Rates

Every six years, Landgate revalues properties in Bridgetown-Greenbushes, and this has occurred in 2025. This revaluation directly affects the rates you'll pay.

While the overall rates revenue is set to increase by 3.3%, this change won't be uniform for everyone. Some property owners may see their rates increase by more than 3.3%, some by less, and a few may even see a decrease compared to last year. This is because the new GRV for each property impacts the final amount.
