Stamp Duty in Australia: A Guide for High-Value Property Purchases
Stamp duty is a state-levied tax imposed on real estate transactions in Australia. It’s calculated using the purchase price or the property’s market value—whichever is higher. Depending on the jurisdiction, rates generally range from 3% to 6% of the property’s value, but steep surcharges apply once you move into the multi-million-dollar brackets.
Premium Rates for Luxury Homes
- New South Wales (NSW): Properties over $3 million incur a special “premium transfer duty.” For a $5 million home, the stamp duty bill can be dramatically higher than for a $1 million purchase.
- Victoria: Above threshold values, rates climb to 6.5%. On a $5 million residence, this equates to roughly $325 000 in stamp duty alone.
- Queensland & Other States: All jurisdictions use progressive scales, with top bands affecting high-end transactions.
Foreign Buyer Surcharges
Non-resident purchasers face an extra 7–8% surcharge in NSW, Victoria, Queensland, South Australia and Western Australia. On a $5 million deal, that’s an additional ~\$400 000 on top of standard stamp duty.
Limited Exemptions & Concessions
Most relief schemes—first-home buyer concessions, spouse transfers, pensioner discounts—are geared toward owner-occupiers in lower value brackets. They rarely apply to luxury property acquisitions.
Investment Property Considerations
Investment purchases in high-value segments may attract stepped-up rates, especially in NSW and Victoria. Note that stamp duty isn’t a deductible expense, but it can form part of your cost base for capital gains tax calculations.
State-By-State Cost Examples
- $500 000 Purchase: Stamp duty ranges from approximately $8 750 in Queensland to $23 928 in the Northern Territory.
- $10 million Purchase: Stamp duty can reach about $611 830 in NSW or $650 000 in Victoria—excluding foreign purchaser surcharges.
Payment Deadlines & Deferral Options
Stamp duty is typically due within 30–90 days of settlement. Some off-the-plan contracts allow you to push payment out for up to 12 months. Many conveyancers handle lodgement and settlement, and certain lenders even let you roll stamp duty into your mortgage.
