How Your Rates Are Calculated

Your rates are calculated in two parts: first, Landgate sets the value of your property, and then the City applies a rate in the dollar to that value. This page explains how property valuations work, how the rate in the dollar is applied, why there is a minimum payment, and what you can do if you think your property has been valued incorrectly.

How your property is valued

The Valuer General at Landgate sets the value of all properties in WA. The City has no role in this process.
  • Gross Rental Value (GRV) applies to most homes. It is the rent your property could earn in a year if it was rented out. Factors like location, size, and features such as a pool or carport are considered. Even if you do not rent your home, Landgate still uses this estimate.
  • Unimproved Value (UV) applies mainly to rural land. It reflects the value of the land itself, without buildings or other improvements.
Valuations are updated regularly: GRV is reviewed every three years in metro areas, and UV is revalued each financial year.

What to do if you think your valuation is wrong

If you think your property valuation is incorrectly valued, you can lodge an objection with Landgate.

Please note:
  • Objections must be lodged within 60 days of receiving your rates notice 
  • The changes only can apply upon advise from Landgate Valuer General Office.
Visit Landgate to learn more about lodging an objection.

How your rates are worked out

Each year, the City sets a rate in the dollar as part of the budget process. Your property’s valuation is multiplied by this figure.

For example:
  • Landgate values your home (GRV) at $20,000
  • The City sets the rate in the dollar at $0.072
  • $20,000 × $0.072 = $1,440 in rates
If your calculated amount is less than the City’s minimum charge, you will pay the minimum instead.

Every property must contribute a minimum amount, even if its valuation is low. This ensures all ratepayers share the cost of community services.

Frequently asked questions

What happens if property values across the City go up?
When values rise or fall, the City may adjust the rate in the dollar to make sure overall rate revenue is balanced. Your rates will not necessarily increase or decrease by the same percentage as your property valuation.
What if my valuation appeal is successful?
If Landgate changes your valuation, the City will adjust your rates and issue an updated notice.
