Do SA first home buyers pay stamp duty?+
No — South Australia completely exempts first home buyers from stamp duty on properties valued up to $650,000. Unlike NSW and VIC, there is no partial concession — if your property exceeds $650,000, full stamp duty applies at standard rates from the first dollar.
Does SA have a first home owner grant?+
SA offers a $15,000 First Home Owner Grant for people building or buying a new home as their principal place of residence, provided the total value does not exceed $650,000. The grant is separate from and cumulative with the stamp duty exemption.
How much stamp duty would I pay on a $500,000 property in SA?+
A $500,000 residential property in SA attracts approximately $19,205 in stamp duty for a standard buyer (not first home buyer). This falls in the $300,001–$500,000 bracket at a rate of $9,705 plus 4.75% on the amount over $300,000.
Are there stamp duty concessions for SA investors?+
No specific stamp duty concession exists for investors in SA — they pay standard rates. The first home buyer exemption only applies to owner-occupiers. Investors can, however, add stamp duty to the cost base of their property for CGT purposes when they eventually sell.
Does SA charge stamp duty on commercial property?+
Yes — commercial property in SA attracts stamp duty at the same rate structure as residential property. The first home buyer exemption does not apply to commercial purchases. Stamp duty on commercial property is generally deductible over time via depreciation.
