South Australia Stamp Duty Calculator 2026

SA abolished stamp duty entirely for first home buyers building or buying new — no price cap. Established homes still cost full duty for everyone, so the new/established choice matters more here than anywhere else.

$30,001 – $50,000$480 + 3% over $30,000

New home? First home buyers pay nothing

SA was the first state to completely abolish stamp duty for first home buyers who buy or build new — a new house, unit, townhouse, off-the-plan apartment, house-and-land package, or vacant land to build on. There is no price cap. Combined with the First Home Owner Grant for new builds, the up-front saving on a $600,000 build is around $30,000.

The catch: established homes get zero relief. A first home buyer purchasing a $550,000 existing house pays the full $24,080. If you're torn between an older house and a new build at similar prices in SA, the duty difference alone can cover a lot of landscaping.

Downsizers join the club in 2026

From 25 March 2026, South Australians aged 60+ who sell their home and buy a newly built home or off-the-plan apartment up to $2,000,000 are also exempt — a deliberate push to free up family homes. Eligibility conditions apply, so check RevenueSA's criteria before contracting.

Investors and everyone else

There's no owner-occupier concession for non-first-home buyers — the standard scale applies whether you live in the property or rent it out. Foreign purchasers add a 7% surcharge. Duty is payable at settlement via your conveyancer.
