SA Stamp Duty 2026: New Home Full Relief, First Home Rules & Foreign Surcharge

In South Australia during the 2026-27 financial year, standard conveyance duty on an $800,000 established home is $37,830. First-home buyers purchasing a new home, off-the-plan property, or vacant land to build on receive full stamp duty relief with no price cap under rules effective from 13 February 2025. Existing homes are not eligible for first-home buyer stamp duty relief in SA. Foreign purchasers face a 7% surcharge, and the First Home Owner Grant is up to $15,000.

This article draws exclusively on the latest South Australian conveyance duty rates, first-home buyer relief measures, and foreign surcharge rules as published by RevenueSA, current for the 2026-27 financial year. SA's approach of restricting stamp duty relief to new homes and off-the-plan purchases only is distinct from most other states and reflects a deliberate policy focus on stimulating new housing construction.

South Australia Conveyance Duty Rates 2026-27

South Australia uses a nine-bracket progressive scale for residential and primary production property, making it one of the more granular duty structures in the country. The rates for 2026-27 are:

1. $0 to $12,000 · 1% of dutiable value
2. $12,001 to $30,000 · $120 plus 2% of amount over $12,000
3. $30,001 to $50,000 · $480 plus 3% of amount over $30,000
4. $50,001 to $100,000 · $1,080 plus 3.5% of amount over $50,000
5. $100,001 to $200,000 · $2,830 plus 4% of amount over $100,000
6. $200,001 to $250,000 · $6,830 plus 4.25% of amount over $200,000
7. $250,001 to $300,000 · $8,955 plus 4.75% of amount over $250,000
8. $300,001 to $500,000 · $11,330 plus 5% of amount over $300,000
9. $500,001 and above · $21,330 plus 5.5% of amount over $500,000

The nine-bracket structure means duty increases in relatively small increments throughout the lower and mid-range, with the final bracket's 5.5% marginal rate applying to all value above $500,000. For a $600,000 property, standard duty is $26,830. For a $1,000,000 property, the duty reaches $48,830.

First Home Buyer Stamp Duty Relief in SA

From 13 February 2025, South Australia restructured its first-home buyer stamp duty arrangements to focus exclusively on new housing supply. The key elements are:

Full stamp duty relief (no transfer duty payable, no price cap):

1. Newly built homes that have never been occupied or sold as a residence
2. Off-the-plan apartments, townhouses, and houses where the contract is entered into before construction is completed
3. Vacant land purchased with the intention of building a new home
4. House and land packages where the land and construction contract form part of a single transaction

No stamp duty relief: 5. Existing or established homes are not eligible for any first-home buyer stamp duty relief in South Australia, regardless of the purchase price

This is a deliberate policy distinction from states like NSW and Victoria, where existing homes are included in first-home buyer stamp duty concessions. In SA, the policy intent is to channel first-home buyer demand toward new construction and stimulate housing supply. A first-home buyer purchasing an existing home in Adelaide priced at $600,000 pays the full standard duty of $26,830 with no concession available.

The relief applies only to the standard conveyance duty component. It does not cover any foreign surcharge that may be payable. Eligibility requires that the purchaser be an Australian citizen or permanent resident aged 18 or over and not have previously owned residential property in Australia.

SA First Home Owner Grant

South Australia offers a First Home Owner Grant of up to $15,000 for eligible first-home buyers constructing or purchasing a new home. Key conditions include:

1. The grant of $15,000 is available for new homes where the construction or purchase contract is entered into within the eligibility period
2. At least one applicant must be an Australian citizen or permanent resident
3. The home must not have been previously occupied or sold as a place of residence
4. The home must be occupied as a principal place of residence for at least six continuous months within 12 months of completion or settlement
5. The grant can be received alongside the full stamp duty relief for new homes, meaning a first-home buyer purchasing an off-the-plan apartment valued at $550,000 receives $15,000 from the FHOG and pays zero conveyance duty, for a combined benefit of approximately $39,080 compared with a non-concessional buyer

Foreign Purchaser Surcharge in SA

South Australia imposes a foreign purchaser surcharge of 7% on the dutiable value of residential property acquired by foreign persons. This surcharge is payable in addition to the standard conveyance duty. The key aspects are:

1. The 7% surcharge rate applies to foreign natural persons, foreign corporations, and trustees of foreign trusts that acquire residential land
2. For a foreign purchaser buying an $800,000 property in Adelaide, the total conveyance cost reaches approximately $93,830: $37,830 standard duty plus $56,000 in foreign surcharge
3. The surcharge is calculated on the full dutiable value of the property
4. The first-home buyer stamp duty relief does not extend to the foreign surcharge. A foreign first-home buyer purchasing a new home would still pay the 7% surcharge even though the standard duty is relieved
5. A foreign person is defined under the Stamp Duties Act 1923 (SA) by reference to the Foreign Acquisitions and Takeovers Act

FAQ

Q: How much stamp duty do I pay on an $800,000 home in South Australia? A: Standard conveyance duty on an $800,000 property in SA for 2026-27 is $37,830. First-home buyers purchasing a new home or off-the-plan property pay zero duty with no price cap, but first-home buyers purchasing an established home pay the full standard rate with no concession available.

Q: Do existing homes qualify for any first-home buyer stamp duty relief in SA? A: No. South Australia does not offer stamp duty relief for first-home buyers purchasing an established home. Relief is restricted to new homes, off-the-plan purchases, and vacant land for building, with no price cap on those categories.

Q: What is the foreign surcharge rate in South Australia? A: SA imposes a 7% foreign purchaser surcharge on the dutiable value of residential property. This is additional to the standard conveyance duty.

Q: Can I receive both the SA FHOG and the first-home buyer stamp duty relief? A: Yes. The up-to-$15,000 First Home Owner Grant for new homes and the full stamp duty relief for new homes or off-the-plan purchases are separate entitlements that can be received together, provided the eligibility criteria for each are met independently.

Q: Why does SA restrict stamp duty relief to new homes only? A: The policy, introduced from 13 February 2025, is designed to stimulate new housing construction and increase supply. By directing first-home buyer benefits exclusively toward newly built homes and off-the-plan purchases, SA aims to accelerate housing delivery rather than subsidise purchases of existing stock.
