Who should use this calculator

Important

  • This calculator does not include any deductions for shared ownership or trust beneficiaries or unitholders. If these apply to you, the calculation is an estimate only and may not reflect your actual liability.
  • If your total land tax liability is less than $20, no assessment will be issued.
  • If you need a calculator for a previous financial year, jump to calculators for previous financial years.

Before you start

  • You will need the site value of your taxable land for the 2025-26 financial year.
  • This can be found on your Land Tax Assessment or requested through South Australian Land Information System (SAILIS), an online platform for land and property information maintained by Land Services SA. A fee may apply.

  • Estimate land tax for a single property

    If you only own one taxable property, you can estimate the land tax payable for that property.

    To calculate the  land tax of a single taxable property:

    1. Enter the site value of the property in the Estimate land tax for a single property section.
    2. Click on the Submit button.
    3. The Estimated land tax payable is shown.

  • Estimate land tax for multiple properties

    • If you own more than one taxable property, you can estimate the total land tax payable across all properties. You can also estimate the apportioned land tax for each individual property.

    To calculate the total estimated land tax of all the taxable properties:

    1. Add together the site values of all the taxable properties and enter that figure into the Estimate land tax for multiple properties section.
    2. Click on the Submit button.
    3. The Estimated land tax payable is shown.

    To calculate land tax apportioned to an individual property:

    1. Without refreshing the page or clearing the value you submitted in the Estimate land tax for multiple properties section, enter the site value of an individual property in the calculate land tax apportioned to an individual property section.
    2. Click on the Submit button.
    3. The Estimate of land tax apportioned to the individual property is shown.
    4. Repeat steps 4 and 5 for each of the individual properties you own. You do not need to start again each time - you can simply type over the last individual property value and press Submit.

    Calculators for previous financial years

    Use the calculator that applies to the land ownership and financial year you are estimating for.

    From the 2020-21 financial year, amendments to the Land Tax Act 1936 resulted in separate assessment of land held on trust, with a higher rate of land tax and a lower land tax threshold being applied to land owned by trusts under certain conditions.

    No calculators are available prior to the 2015-16 financial year.
