• What is a Stamp Duty Calculator?

  A Stamp Duty (also called transfer duty or conveyance duty) calculator estimates the one-off state/territory tax payable when you buy property. It factors in purchase price/market value, location, property type and your buyer status (e.g., first-home buyer). Stamp duty is a state/territory tax, not an ATO tax.

• How does a Stamp Duty Calculator work in Australia?

  It applies your state/territory’s rules to the dutiable value (generally the greater of the price paid or market value), then layers on any relevant surcharges or concessions (e.g., first-home, principal place of residence, off-the-plan, foreign purchaser).

• What information do I need to use a Stamp Duty Calculator?

  • Property details: price/estimated market value, address/state, new vs established, off-the-plan vs completed, land vs home.

  • Buyer details: first-home status, intended occupancy (home vs investment), Australian citizen/PR vs foreign purchaser, buying entity (individual, company, trust).

  • Timing: contract date (some concessions depend on it).

• Why should I use a Stamp Duty Calculator?

  To budget for one of the largest upfront purchase costs and see if concessions might reduce it. (You’ll also pay separate government registration/transfer fees.)

• When is stamp duty payable?

  Timeframes vary by state. As one example, in NSW you must pay within 3 months of signing (sooner for settlement). Other states have their own deadlines.

• What concessions or exemptions might apply?

  These are state-based and change over time. Examples:

  • QLD: first-home transfer duty concessions (thresholds and partial concessions apply).

  • VIC: off-the-plan duty concession (eligibility and scope depend on contract date and occupancy).SA: stamp duty abolished for eligible first-home buyers who buy/build new homes (no property value cap). 
    Always check your state revenue office for the latest rules.

• Do foreign buyers pay extra duty?

  Most states/territories impose a foreign purchaser surcharge on top of standard duty (rates and rules differ; ACT currently has no surcharge). Check the state’s criteria and any trust/company rules.

• Is stamp duty the same as land tax?

  No. Stamp duty is a one-off tax when you acquire property. Land tax/rates are ongoing. The ACT is mid-way through a long transition away from stamp duty toward higher general rates.

• How is stamp duty calculated?

  Duty scales are tiered/progressive and differ by state. Some states also have premium brackets for higher-value residential land. Calculators use the state’s scale applicable to your contract date and buyer type.

• What about buying off-the-plan?

  Some jurisdictions reduce dutiable value for eligible off-the-plan purchases used as a home, lowering duty. Rules hinge on contract date and occupancy requirements.

• What if I buy through a company or trust?

  Different rules can apply (including for foreign purchaser surcharges and concessions eligibility). Get advice before exchanging contracts.
