Stamp Duty in Australia — What You Need to Know
Stamp duty (also called transfer duty) is a state government tax charged when you buy a property. The amount varies significantly by state — a $750,000 home in NSW costs around $29,000 in duty, while the same home in QLD attracts around $15,750. Every state uses a progressive bracket system where higher-value properties attract a higher marginal rate.
For first home buyers, concessions can eliminate or significantly reduce the bill. NSW, VIC, QLD and WA all have exemption thresholds below which no duty is payable. Tasmania offers a 50% discount regardless of property value, and the ACT has an income-tested concession scheme.
Stamp duty is in addition to the purchase price and must be paid at settlement. Budget for conveyancing ($1,000–$2,500), building and pest inspections ($400–$800), and lender fees on top. Use this calculator to plan your full purchase cost before you make an offer.
Frequently Asked Questions
How is stamp duty calculated in Australia?
Stamp duty is calculated using progressive bracket rates that vary by state. Each state applies a fixed base amount plus a percentage of the property value above each bracket threshold. Use the calculator above to get the exact figure for your state.
Do first home buyers pay stamp duty in Australia?
Many states offer concessions or full exemptions for first home buyers. NSW exempts properties under $800,000; VIC under $600,000; QLD under $500,000; WA under $430,000. Tick the 'first home buyer' box in the calculator to see the rate that applies to you.
Which state has the highest stamp duty in Australia?
South Australia and NSW tend to have the highest stamp duty rates for mid-range properties. On a $750,000 home, NSW buyers pay around $29,000 and SA buyers around $30,000. QLD and WA are generally lower for the same price point.
When do you pay stamp duty?
Stamp duty is typically due within 30 days of settlement (the date you take legal ownership of the property). Your conveyancer or solicitor will arrange payment to the relevant state revenue authority on your behalf.
Is stamp duty tax deductible?
Stamp duty on your primary residence is not tax deductible. For investment properties, stamp duty is added to the cost base of the asset and reduces your capital gains tax liability when you eventually sell — but it cannot be claimed as an annual expense.
