How stamp duty works in South Australia

SA has one rate scale for dutiable land, from $1.00 per $100 up to $12,000, rising to $5.50 per $100 above $500,000. Rates are charged per $100 or part of $100. SA has no general owner-occupier concession, so homes and investments pay the same.

From 15 September 2026 the Stamp Duties (Residential Purposes and Residential Land) Amendment Act 2026 clarified what counts as residential and qualifying land. Vacant land zoned to allow housing is residential, and hotels, motels, purpose-built student accommodation and nursing homes are excluded from residential treatment. The rates did not change.

First home buyers in SA

For contracts from 6 June 2024, eligible first home buyers pay no stamp duty on a new home, an off-the-plan apartment or vacant land to build a home on, whatever the value. Established homes, including knock-down-rebuilds, don't qualify.

For contracts from 13 February 2025 the relief doesn't cover the foreign ownership surcharge. Contracts between 15 June 2023 and 5 June 2024 had value caps of $650,000 to $700,000 for new homes and $400,000 to $450,000 for vacant land.
