How your rates are calculated
The rates calculation starts with determining the budget we need set to deliver our local services. This budget amount is then divided among ratepayers, although not everyone pays the same amount.
Rates are calculated by multiplying a property’s valuation by the differential rate in the dollar set by Council. This is subject to an annual minimum rate which is set each year by Council.
Your valuation is determined by the Valuer General at Landgate, a separate organisation. The Valuer General assigns non-rural properties a Gross Rental Value (GRV) and rural properties an Unimproved Value (UV).
The Gross Rental Value, or GRV, represents the gross annual rental that a property might reasonably be expected to earn annually if it were rented, including rates, taxes, insurance and other outgoings. For non-residential properties, GST is also included.
Your Gross Rental Value can be found on your rates notice. You can appeal your Gross Rental Valuation within 60 days from the date of issue of your Annual Rate Notice by completing an objection form on the Landgate website.
Unimproved Value, or UV, is the value of land only. It does not include the value of your home, other structures or improvements. For land within the metropolitan area, the UV does include merged improvements such as drainage, levelling and filling.
