Frequently asked questions
How is stamp duty calculated in South Australia?
SA stamp duty is progressive from 1% up to 5.5% above $500,000, with no separate owner occupier scale. The calculator applies the current RevenueSA rate table to the purchase price.
Do first home buyers pay stamp duty in South Australia?
Only on established homes. First home buyers building or buying a new home or vacant land to build on pay no stamp duty, with no price cap. Established homes get no first home relief in SA, so full duty applies.
How much extra do foreign buyers pay in South Australia?
Foreign purchasers pay a 7% surcharge on residential land value in addition to standard duty. The calculator adds it when the foreign buyer toggle is on.
