Stamp duty is a form of tax charged by state and territory governments during the sale and transfer of property purchases. The rate of tax charged varies between states and territories, as well as the type and cost of the property. Unfortunately, it is also a cost that often creeps up on many property buyers.

Our Stamp Duty Calculator provides a guide on how much stamp duty you could be charged on your property purchase in Western Australia (when the WA tab is selected along the top of the calculator); it is also designed to highlight certain stamp duty exemptions or grants for which you may be eligible.

This tool is particularly helpful when used in conjunction with some of our other calculators, like our Property Buying Cost Calculator, Loan Comparison Calculator, and our Borrowing Power Calculator.

How is stamp duty calculated in Western Australia?

In WA, stamp duty is charged on a sliding scale based on the greater of the property’s purchase price, or its unencumbered value.

Click our “rates and thresholds” button towards the bottom left of our calculator to see the current stamp duty rates and thresholds for WA. The information within this pop-up menu includes:

  • general rate
  • residential rate
  • concessional rate
  • First Home Owner rate – established homes
  • First Home Owner rate – vacant land
  • stamp duty: vacant land
  • mortgage registration fee, which is a set amount in WA and therefore doesn’t change on our stamp duty calculator
  • land transfer fee
  • First Home Owner Grant.

Take a look at a detailed breakdown of the information you’re required to input into our calculator.

1. Enter your details

  • Value of property: In this field, type in the value of the property you’re planning to purchase.
  • Are you a first home buyer? Click either “yes” or “no”. If you are a first home buyer, you may be eligible to receive certain grants and concessions. You may be eligible for the:
    • First Home Owner Grant. This one-off payment of $10,000 is applicable to eligible purchasers who buy a new residential dwelling. The grant is applicable if the total value of the home stays below these cap amounts:

– $750,000 if the property is located south of the 26th parallel of south latitude (from Kalbarri 6536);

– $1,000,000 if the property is located north of the 26th parallel of south latitude (from Denham 6537).

  • Property type: Select whether you’re purchasing your property as your primary residence or as an investment. To qualify for the First Home Owner Grant, you must occupy your home as your principal place of residence for a continuous period of at least six months, starting within 12 months of the eligible transaction.
  • Are you purchasing? Click on either “established home”, “new home”, or “vacant land”. For vacant land purchase, stamp duty is levied on both the land value and building cost. If you purchase vacant land, you will be charged stamp duty at the general rate. Once a house is built on the land that is eligible for the First Home Owner Grant, a refund may be available on application. Otherwise, the grant does not apply to vacant land or established homes.
  • Property location: Select whether your property is located south of the 26th parallel (from Kalbarri 6536), or north of the 26th parallel (from Denham 6537).

2. Government fees

The results in this field include:

  • Stamp duty on property: This is the cost of duty you would be required to pay for your property based on the information provided.
  • Mortgage registration: WA charges $168.70 for mortgage registration.
  • Transfer fee: WA calculates the transfer fee against the value of the property. Further information on transfer fees can be found by clicking the “rates and thresholds” button on the bottom left of our calculator.

The total amount of these costs appears next to “total government fees”.
