Stamp Duty on Investment Property - State by State

What this calculator does

Run this scenario in DocketMath using the Stamp Duty calculator.

DocketMath’s stamp-duty calculator helps you estimate stamp duty and other related, transfer-based government charges when you buy an investment property in Australia. Because stamp duty rules are set by each state and territory, the calculator is built to support state-by-state variations rather than a single national rate.

In practical terms, the tool helps you answer questions like:

• “If I buy an investment property for $650,000, what stamp duty might apply in NSW vs VIC vs QLD?”
• “How does the estimate change if the purchase price increases by $50,000?”
• “What happens to the estimate if I buy in a different state, or if my situation includes common investment-related conditions?”

What you’ll typically input (and why it matters)

Your inputs generally affect the output through:

• Jurisdiction (state/territory): stamp duty is state/territory-based, so rates, thresholds, and categories can differ.
• Purchase price: duty often scales with the value, using that state/territory’s banding or rate rules.
• Investment / non-owner-occupied classification: many jurisdictions apply higher duty or surcharges/premium rates depending on how the property is classified.
• Transaction type and structure: the tool may ask about the type of transfer (and, in some cases, other transaction features) because they can influence how duty is assessed.
• Timing or contract type (where relevant): in some jurisdictions, off-the-plan or other contract timing can change assessment timing and sometimes the calculation approach.

When to use it

Use DocketMath’s /tools/stamp-duty calculator when you need a practical planning number for a property purchase involving investment purposes, such as:

• You’re checking upfront costs before signing a contract for an investment property.
• You’re comparing buying in different locations (e.g., ACT vs NSW or SA vs WA) to understand duty differences.
• You’re stress-testing your budget by changing inputs (for example, how duty scales when purchase price rises).
• You’re modelling common transaction situations where duty treatment may differ by jurisdiction (including scenarios like off-the-plan—depending on what the calculator supports).

Timing checkpoints

You’ll usually get the most value from the estimate at stages like:

• Before conveyancing: to sanity-check affordability and total cash required.
• During negotiations: to understand whether price adjustments or special terms might offset upfront duty costs.
• Before settlement: to confirm your working estimate, then reconcile against the final assessment your conveyancer/solicitor receives from the revenue office.

Step-by-step example

Below is a practical example showing how the results can shift when you change state. Use DocketMath: /tools/stamp-duty and adjust the assumptions to match your situation.

Scenario

• You’re buying an investment property
• Purchase price: $650,000
• Buying as an individual (not a company or trust)
• Treated as a standard transfer of land (the exact available selections vary by jurisdiction within the tool)

Step 1: Choose jurisdiction

In /tools/stamp-duty, select the AU state/territory where the property is located.

For this example, compare NSW and VIC.

Step 2: Enter the purchase price

Enter $650,000.

• If you increase the purchase price (e.g., to $700,000), the estimated duty should rise (often not perfectly linearly because of banding/thresholds).
• If you reduce it (e.g., to $600,000), the estimate should fall.

Step 3: Confirm investment classification inputs

Many calculators ask you to indicate whether the purchase is investment / non-owner-occupied (or similar wording).

This matters because some jurisdictions apply one or more of the following:

• Different duty rates
• Surcharges/premium duty for non-owner-occupied acquisitions
• Different treatment for categories compared with owner-occupied property

Step 4: Review the output and what it includes

DocketMath will return an estimated duty figure for your selected jurisdiction.

Depending on the calculator’s design for your inputs, you may also see a breakdown (for example, how it applies rate bands and category effects).

What changes state-to-state?

At a high level:

• Some states impose higher duty for investment or non-owner-occupied acquisitions.
• Thresholds and banding differ, so the same purchase price (like $650,000) can produce meaningfully different outcomes across states.

Common scenarios

Investment property purchases aren’t one-size-fits-all. The scenarios below are common and often change either what inputs you’ll select in the tool, or how your results should be interpreted.

1) Buying an investment property vs buying to live in first

Stamp duty assessments typically look at the transaction facts at transfer, not what happens years later. If you rent out from day one, it’s often treated as an investment acquisition.

Checklist

2) Off-the-plan purchases

Some jurisdictions treat off-the-plan differently—sometimes due to assessment timing and contract features.

Checklist

3) Buying in a different state (relocation or investing from afar)

Comparing jurisdictions is one of the biggest reasons people use this tool.

Checklist

4) Transfers involving entities (trusts/companies)

If the purchase involves structures beyond an individual (for example, a trust or company), duty can be affected by the transfer mechanism or the instrument being transferred.

Checklist

5) Exemptions, concessions, and special relief

Even for investment property, certain reliefs can exist but are highly state-specific and often strict.

A practical approach is:

1. run a baseline estimate using standard inputs, then
2. adjust only if you’re confident the relief applies and the tool supports the required category.

Checklist

Tips for accuracy

You’ll usually get the most reliable estimate if your inputs reflect the figures and classifications that appear in your contract.

1) Use the correct purchase price figure

Stamp duty is generally based on the consideration (price). Contracts can include components that affect what should be entered.

Practical approach

2) Match jurisdiction to property location

Stamp duty generally follows the location of the property.

3) Treat investment classification carefully

Choosing the wrong category can materially change the estimate.

4) Don’t confuse stamp duty with other property costs

This calculator focuses on stamp duty-type charges. But purchases also commonly involve other costs like:

• Conveyancing and legal fees
• Lender fees and settlement costs
• Possible land tax impacts (different from stamp duty)
• Council rates and utility adjustments at settlement

Budgeting tip

5) Re-run the estimate when key numbers change

Use the tool for scenario testing, for example:

6) Save your assumptions

If you need to discuss the result with your conveyancer, accountant, or partner, having your assumptions makes reconciliation easier.
