Stamp Duty Calculator (Australia)

It estimates the property transfer duty payable when buying real estate in Australia, using indicative state-based rates, thresholds, and common concessions to give a quick scenario-based estimate. Results aren't official and should be treated as guidance only, since final duty is assessed by the relevant state revenue office.

Yes — it's designed for Australian buyers and reflects how stamp duty is commonly structured across states and territories. Rates and concessions vary by location, so it provides an estimate rather than a final figure. Always cross-check with your state revenue authority before making financial decisions.

It provides a close estimate based on publicly available duty frameworks and typical thresholds. Accuracy depends on correct inputs such as property value, buyer type, and concessions, and it doesn't replace official assessments, which may include additional rules or updates.

Yes. Stamp duty can differ significantly between Sydney (NSW) and Melbourne (VIC) because each state sets its own rates and concessions. You can compare scenarios by adjusting property values and buyer details, which helps you understand metro-specific cost differences before committing.

Stamp duty rates are usually state-based rather than metro-specific, but property prices in metro areas are often higher, so city buyers may pay more in dollar terms. Comparing metro versus regional scenarios makes this realistic.

A common one is assuming stamp duty is a flat percentage across Australia. Another is forgetting to factor in buyer type, concessions, or surcharges that may apply. The tool reduces these errors, but validate your assumptions carefully.

No — that's a common myth. First-home buyer concessions depend on the state, property value, and eligibility criteria. The tool helps estimate potential concessions, but outcomes vary and are subject to state rules.

The results show an indicative stamp duty range based on your inputs. Reviewing low, base, and high scenarios helps you understand sensitivity to price changes, so use the estimate as a planning tool rather than a guaranteed payable amount.

It can indicate higher duty outcomes where foreign buyer surcharges may apply. These surcharges vary by state and can change, so confirm your final liability with the relevant state authority or a qualified advisor.

ASIC and MoneySmart encourage consumers to compare costs and run multiple scenarios before major financial decisions. Using this tool aligns with that guidance by helping you understand upfront property costs, though it doesn't replace professional or official advice.

Stamp duty itself is set by states, but ATO, ABS, and RBA data often influence broader property and economic assumptions. This tool uses common market frameworks rather than official datasets, so it's designed for estimation, not compliance or reporting.

Yes. If you're buying from overseas, you can plan property purchases and estimate duty in AUD even when your income is in another currency. Actual payable amounts may change because of foreign buyer rules and exchange rate movements.

Account for AUD exchange rate fluctuations when budgeting for stamp duty. The estimate is in AUD, but remittance timing can affect the final cost, so planning a buffer helps you manage currency risk responsibly.

Yes. Special cases like off-the-plan purchases, transfers between family members, or complex ownership structures can affect duty and may not be fully captured by a general calculator. Professional advice is recommended for non-standard transactions.

Yes. It's advisable to recalculate regularly because thresholds, concessions, and property prices change. Updating your assumptions before making an offer reduces surprises at settlement.

Understanding stamp duty upfront lets you plan your savings, deposit size, and total purchase costs more confidently. Use the estimate alongside loan repayments and ongoing costs to assess affordability and support informed, low-stress property decisions.

First-home buyer exemptions and concessions vary significantly by state (2026 estimates): NSW typically exempts up to ~$650k, VIC ~$600k, QLD ~$500k, WA ~$430k, SA ~$450k, with ACT and NT offering full or partial exemptions. These thresholds change annually, so verify with your state's Office of State Revenue or the ATO for current rates.

Most Australian states apply a foreign buyer surcharge of 7–15% on top of the regular duty — for example, NSW adds an 8% surcharge on purchases by non-Australian residents. Some states offer exemptions for permanent residents, so clarify your residency status with your state revenue authority before calculating.

The ATO provides general tax guidance, but state-specific stamp duty is administered by each state's Office of State Revenue (for example, Revenue NSW or the State Revenue Office Victoria), with final assessment at settlement. This tool provides estimates, so always cross-check with your conveyancer or state authority for official duty amounts.
