# Stamp Duty South Australia 2026

SA stamp duty rates and first home buyer relief. Full exemption for new homes (no cap), but zero relief for established homes. Building saves $15K-$30K+.

SA stamp duty rates and first home buyer relief. Full exemption for new homes (no cap), but zero relief for established homes. Building saves $15K-$30K+.

Quick answer: SA stamp duty on a $500,000 property is approximately $21,330. First home buyers building new pay zero stamp duty with no property value cap (from June 2024). However, SA offers zero relief for established homes — the only state with this policy. Building instead of buying saves $15,000–$30,000+ because you only pay duty on the land. Combined with the $15,000 FHOG, first home buyers building new save $36,000–$48,000+ total. Updated April 2026 based on RevenueSA data.

“South Australia’s stamp duty policy is the most polarised in Australia — best in the country for new builds, worst for established homes. If you’re a first home buyer in SA, building new isn’t just a preference, it’s a financial necessity.”
— Emma Whitfield, Property Finance Analyst at BuildBudget

This is the starkest difference in Australia. SA first home buyers building new pay zero stamp duty and get $15,000 FHOG (RevenueSA). SA first home buyers buying established pay full stamp duty (~$25,580 on a $650K property) but still get the $15,000 FHOG. The building advantage is $25,580 in stamp duty alone. You may also qualify for the $15,000 First Home Owner Grant in SA.

Not complicated, but you need to get the paperwork right.
