This tool is designed to assist in calculating your land tax based on the taxable value of your land. However, it should not be considered a comprehensive assessment of your total income tax obligations. The calculator is tailored exclusively for Australian resident taxpayers. If you have complex financial situations or are uncertain about certain aspects of your taxes, it is recommended to consult with a qualified tax professional or accountant for personalized advice and verification of your calculations. Should you require further assistance, please consider reaching out to Investax for a professional assessment of your calculation.
SA Land Tax Calculator
Owning investment property, vacant land, commercial property or multiple taxable landholdings in South Australia can create an annual land tax obligation. For property investors, land tax is an important holding cost that can affect rental yield, cash flow, portfolio growth and long-term investment planning.
The Investax SA Land Tax Calculator helps South Australian property owners estimate potential land tax based on taxable site value and the applicable South Australian land tax rates. The calculator is designed for individuals, companies and trusts, making it useful for investors who want to understand possible land tax exposure before receiving an assessment or buying another property.
In South Australia, land tax is calculated using different thresholds and rates depending on how the land is held. General thresholds and rates apply to non-trust land ownerships and some trusts that meet specific criteria, while trust thresholds and rates apply to trusts that do not meet the criteria for general rates.
This calculator provides an estimate only. The final land tax result can depend on site value, ownership type, aggregation rules, joint ownership, related corporations, trust ownership, exemptions, RevenueSA records and the official land tax assessment.
For property investors who need more than a calculator estimate, Investax provides investment property tax advice and strategic property tax planning support.
Land tax is a state-based tax charged on taxable land owned in South Australia. It is separate from income tax, council rates, emergency services levy, stamp duty and capital gains tax.
SA land tax may apply to:
-
Investment residential properties
-
Vacant land
-
Commercial properties
-
Holiday homes
-
Land held by companies
-
Land held by trusts
-
Multiple landholdings
-
Jointly owned land
-
Land held by related corporations
-
Some mixed-use properties
Land tax is generally based on the site value of taxable land, not the full market value of the property including buildings. RevenueSA states that taxpayers need the site value of taxable land for the relevant financial year when estimating land tax.
The SA Land Tax Calculator estimates land tax using the taxable site value of land and the relevant South Australian land tax rate. It helps property owners quickly estimate possible land tax before reviewing a formal assessment.
To use the calculator:
1. Select the Ownership Type
Choose whether the land tax calculation relates to an individual, company or trust. This is important because trust land may be assessed using different thresholds and rates from general land ownership.
2. Enter the Land Value
Enter the total taxable site value of the South Australian land. If more than one taxable property is owned, the combined value may need to be considered.
3. Review the Land Tax Rate
The calculator applies the relevant rate based on the entered land value and ownership type. South Australian land tax rates are progressive, meaning higher taxable site values generally attract higher tax amounts.
4. Calculate the Estimated Land Tax
After entering the details, the calculator provides an estimated land tax result. This should be used as a planning guide only and should not replace a formal RevenueSA assessment or professional advice.
For the 2025–26 land tax year, RevenueSA lists the general tax threshold as $833,000 and the trust tax threshold as $25,000. RevenueSA also explains that land tax thresholds are adjusted each year based on changes in property site values, as determined by the Valuer-General.
This means South Australian property investors should review updated thresholds each year before relying on an old estimate.
The 2025–26 general land tax rates apply to non-trust land ownerships and some trusts that meet specific criteria. RevenueSA lists the general rates as follows:
| Total Taxable Site Value | Amount of Tax |
|---|---|
| Does not exceed $833,000 | Nil |
| Exceeds $833,000 but not $1,338,000 | $0.50 for every $100 or part of $100 above $833,000 |
| Exceeds $1,338,000 but not $1,946,000 | $2,525 plus $1.00 for every $100 or part of $100 above $1,338,000 |
| Exceeds $1,946,000 but not $3,116,000 | $8,605 plus $2.00 for every $100 or part of $100 above $1,946,000 |
| Exceeds $3,116,000 | $32,005 plus $2.40 for every $100 or part of $100 above $3,116,000 |
For official guidance, visit the RevenueSA land tax rates and thresholds page.
South Australia has separate trust land tax rates for trusts that do not qualify for assessment at the general rates. RevenueSA lists the 2025–26 trust threshold as $25,000 and provides separate trust rates for taxable site values above that amount.
| Total Taxable Site Value | Amount of Tax |
|---|---|
| Does not exceed $25,000 | Nil |
| Exceeds $25,000 but not $833,000 | $125 plus $0.50 for every $100 or part of $100 above $25,000 |
| Exceeds $833,000 but not $1,338,000 | $4,165 plus $1.00 for every $100 or part of $100 above $833,000 |
| Exceeds $1,338,000 but not $1,946,000 | $9,215 plus $1.50 for every $100 or part of $100 above $1,338,000 |
| Exceeds $1,946,000 but not $3,116,000 | $18,335 plus $2.40 for every $100 or part of $100 above $1,946,000 |
| Exceeds $3,116,000 | $46,415 plus $2.40 for every $100 or part of $100 above $3,116,000 |
Because trust rates can create a different result from general rates, land held through a family trust, discretionary trust, unit trust or fixed trust should be reviewed carefully before purchase.
A South Australia land tax calculator can help property investors estimate possible land tax before making financial decisions. Many investors calculate loan repayments, rental income, insurance and council rates but forget to include land tax as an annual holding cost.
Using an SA land tax calculator can help:
-
Estimate annual land tax before receiving an assessment
-
Understand whether taxable site value may exceed the threshold
-
Compare general rates and trust rates
-
Review cash flow for investment property
-
Prepare before buying another SA property
-
Understand the effect of aggregation rules
-
Review trust or company ownership implications
-
Identify when professional property tax advice may be needed
For broader tax support, Investax provides property tax specialist services for Australian property investors.
Investment property is one of the most common reasons land tax applies in South Australia. A residential rental property may be taxable if it does not qualify for an exemption and the total taxable site value exceeds the relevant threshold.
Land tax can affect an investment property’s real return. A property may appear profitable when only rent, interest and council rates are considered, but annual land tax can reduce net cash flow.
Property investors should review land tax when considering:
-
Rental yield
-
Negative gearing position
-
Annual cash flow
-
Property holding costs
-
Purchase structure
-
Refinancing decisions
-
Portfolio growth
-
Future sale timing
-
Capital gains tax planning
-
Long-term investment strategy
For investors who also need to estimate tax on future property sales, Investax provides a capital gains tax calculator.
South Australian land tax is calculated using a tiered system based on the total taxable site value of all land held under an ownership. RevenueSA explains that even if individual properties have site values below the threshold, land tax may still apply if the combined value exceeds the threshold.
This is important for investors who own multiple SA properties. For example, one property may sit below the threshold, but two or three taxable properties together may create a land tax liability.
Investors should review the combined taxable value of:
-
Residential investment properties
-
Vacant land
-
Commercial land
-
Jointly owned land
-
Trust-held land
-
Company-owned land
-
Land held through related corporations
Joint ownership can affect how land tax is assessed. RevenueSA explains that where land is jointly owned, the taxable site values of land within the joint ownership are combined first, and an individual’s ownership may then be assessed separately with a deduction for their share of land tax assessed in the joint ownership.
This can be relevant where:
-
A couple jointly owns investment property
-
One owner also owns property separately
-
Family members jointly own land
-
Business partners own land together
-
Different ownership percentages apply across properties
Joint ownership should be reviewed before buying additional land, especially where one owner already holds other taxable land in South Australia.
Land held through a trust can create different land tax outcomes. RevenueSA states that land held on trust under a discretionary, fixed or unit trust is subject to a higher set of trust land tax rates and a lower land tax threshold, unless the trust meets criteria for the general rates.
Trust ownership may be used for:
-
Family wealth planning
-
Asset protection
-
Estate planning
-
Investment flexibility
-
Succession planning
-
Business structuring
However, the land tax cost should be reviewed before purchasing property through a trust. A structure that is useful for asset protection or income distribution may create a higher annual land tax obligation.
Investax provides investment structure services in Australia for investors considering personal, joint, trust, company or SMSF ownership.
RevenueSA states that general land tax rates may apply where a trust is an excluded trust, a fixed trust where all nominated beneficiaries have been notified, a unit trust where all nominated unitholders have been notified, or certain discretionary trust arrangements involving designated beneficiaries. Trust rates apply where the trust does not meet the criteria for assessment at general rates.
This means trust land tax treatment should not be guessed. The trust deed, acquisition date, beneficiary nomination status and RevenueSA notification history may all affect the land tax outcome.
For official guidance, visit the RevenueSA land held on trust guide.
Companies may hold South Australian land for investment, development, commercial or business purposes. However, company ownership can affect how land tax is assessed.
RevenueSA explains that where two or more corporations are related, the land they own is assessed for land tax as if the land were owned by one corporation.
This can be relevant where:
-
Multiple companies own different properties
-
A company owns investment land
-
Related entities hold commercial property
-
A corporate group owns development sites
-
A business structure includes land-rich entities
For business owners, Investax provides business structure services to support tax-effective planning.
Vacant land may be subject to land tax if it is taxable and does not qualify for an exemption. Investors sometimes assume land tax only applies to rental property, but vacant land can also be included in taxable site value calculations.
Vacant land may include:
-
Residential development land
-
Land held for future construction
-
Subdivision land
-
Commercial development sites
-
Land banking sites
-
Rural residential land not eligible for exemption
-
Land awaiting planning approval
Vacant land can create cash flow pressure because it may not produce rental income while still generating holding costs such as council rates, insurance, loan interest and land tax.
Commercial property may also be subject to South Australian land tax. This can include offices, shops, warehouses, mixed-use buildings, industrial land and business premises.
Commercial property owners should consider:
-
Taxable site value
-
Ownership structure
-
Lease terms
-
Whether land tax can be recovered from tenants
-
Company or trust ownership
-
Related corporation rules
-
Cash flow impact
-
Future capital gains tax planning
Commercial land tax can be more complex where the property is held through a trust, company or related-party structure.
A principal place of residence may not be subject to land tax where the relevant conditions are satisfied. However, property owners should not assume that every residential property is exempt.
Land tax exposure should be reviewed where:
-
A former home has become a rental property
-
A home is partly used to earn income
-
Multiple homes are owned
-
A holiday home is held
-
Land is vacant or being developed
-
Land is owned through a trust or company
-
Ownership has changed during the year
If a property has changed use, professional advice may help confirm whether the land should be included in the land tax calculation.
Land tax becomes more important as a property portfolio grows. A single South Australian property may not create a land tax liability, while multiple taxable properties may exceed the threshold when combined.
Property portfolio planning should consider:
-
Total SA taxable site value
-
Personal ownership
-
Joint ownership
-
Trust ownership
-
Company ownership
-
Related corporations
-
Future property purchases
-
Property sale timing
-
Capital gains tax exposure
-
Asset protection goals
-
Estate planning objectives
-
Cash flow after land tax
For investors who want to protect assets and plan long-term ownership, Investax provides asset protection services in Australia.
Land tax is an annual cost, so it should be included in property cash flow forecasts. This is especially important where interest rates, insurance, repairs and property management fees are already reducing net returns.
Annual property costs may include:
-
Loan interest
-
Council rates
-
Water charges
-
Insurance
-
Repairs and maintenance
-
Property management fees
-
Strata fees
-
Accounting fees
-
Land tax
-
Tax advice fees
A property that looks profitable before land tax may produce a weaker after-tax result once all annual holding costs are included.
Land tax and capital gains tax are different taxes, but both can affect property investment decisions. Land tax applies annually while a property is held. Capital gains tax may apply when the property is sold.
Before selling a South Australian investment property, investors should consider:
-
Annual land tax cost
-
Expected capital gain
-
Selling costs
-
Ownership period
-
50% CGT discount eligibility
-
Capital losses
-
Depreciation and capital works adjustments
-
Ownership structure
-
After-tax sale proceeds
Investax can help investors review both annual holding costs and future CGT exposure as part of a broader property tax plan.
South Australian land tax mistakes can lead to unexpected assessments, cash flow pressure or poor investment decisions.
Common mistakes include:
-
Assuming land tax only applies to rental property
-
Forgetting vacant land
-
Ignoring commercial land
-
Reviewing each property separately instead of aggregated taxable value
-
Assuming the general threshold applies to all trusts
-
Buying through a trust without reviewing trust land tax rates
-
Not checking joint ownership rules
-
Ignoring related corporation aggregation
-
Confusing site value with full property market value
-
Forgetting land tax in cash flow forecasts
-
Not reviewing assessment details
-
Waiting until after purchase to get advice
A calculator is useful for early planning, but professional advice is recommended where ownership, trust status, exemption eligibility or aggregation rules are unclear.
Before seeking professional advice, property owners should prepare relevant documents and details.
Useful records may include:
-
RevenueSA land tax assessment notice
-
Site value details
-
Property title information
-
Purchase contracts
-
Settlement statements
-
Ownership percentage details
-
Trust deed, if applicable
-
Company structure details, if applicable
-
Beneficiary or unitholder details, where relevant
-
Rental property information
-
Principal residence evidence, where relevant
-
Prior year land tax assessments
-
Property portfolio summary
-
Loan and finance details
-
Council rate notices
Good records can help confirm whether an assessment appears correct and whether any trust, joint ownership, company or exemption issue should be reviewed.
Professional advice may be useful where:
-
Multiple SA properties are owned
-
Land is held through a trust
-
Land is held by a company
-
Related corporations own land
-
Land is jointly owned
-
A property portfolio is growing
-
Site values have increased
-
A land tax assessment appears incorrect
-
Vacant land is owned
-
Commercial property is owned
-
A new investment property is being purchased
-
Ownership is being restructured

The Investax SA Land Tax Calculator provides a helpful estimate, but land tax should not be reviewed in isolation. The final outcome may depend on total taxable site value, ownership type, aggregation rules, trust status, joint ownership, related corporations, exemptions and the official RevenueSA assessment.
Before buying another South Australian property, restructuring ownership or responding to a land tax assessment, professional advice can help reduce risk and improve planning.

What is an SA land tax calculator?
An SA land tax calculator estimates possible land tax payable in South Australia based on taxable site value and the relevant South Australian land tax rates. It can help property investors and landowners plan annual property holding costs.
Who pays land tax in South Australia?
Land tax may apply to owners of taxable land in South Australia, including investment property, vacant land, commercial land and some land held through trusts or companies.
What is the SA general land tax threshold?
For the 2025–26 land tax year, the South Australian general land tax threshold is $833,000.
What is the SA trust land tax threshold?
For the 2025–26 land tax year, the South Australian trust land tax threshold is $25,000.
Is SA land tax calculated on each property separately?
Not usually. RevenueSA explains that land tax is calculated using the total taxable site value of all land held under an ownership, so combined values can create a land tax liability even if individual property values are below the threshold.
Do trusts pay different land tax in South Australia?
Yes. Land held on trust may be taxed at trust land tax rates or general land tax rates depending on the circumstances. Trust land tax rates can apply where the trust does not meet the criteria for general rates.
Does SA land tax apply to vacant land?
Vacant land may be subject to land tax if it is taxable and does not qualify for an exemption. Investors holding vacant land should include it when reviewing their total taxable site value.
Does joint ownership affect SA land tax?
Yes. Joint ownership can affect how land tax is assessed. RevenueSA explains that jointly owned land can be assessed first in the joint ownership, with further assessment at the individual ownership level where relevant.
Should I get advice before buying another SA investment property?
Yes. Advice is recommended before buying another property, especially where multiple properties are owned, land is held through a trust or company, related corporations are involved, or site values are close to the threshold.
