Stamp duty in Australian Capital Territory

The ACT is progressively abolishing stamp duty, replacing it with higher annual land rates (essentially a property tax). Duty rates are being reduced each year as part of a multi-decade transition. The ACT also offers an owner-occupier concession and has the Home Buyer Concession Scheme providing full stamp duty exemption for homes up to $1 million (income-tested).

Policy note: The ACT's stamp duty abolition means rates are already lower than comparable prices in NSW or VIC. The Home Buyer Concession Scheme (income threshold ~$170,000 for individuals, ~$250,000 for couples) can provide full duty exemption on properties up to $1 million. However, ongoing land rates are higher than in other jurisdictions.

Foreign buyer surcharge: The ACT does not currently impose a foreign buyer stamp duty surcharge, though foreign owners may face higher land tax rates.

Buying in this price range

Between $800,000 and $1.3 million, stamp duty becomes a major transaction cost — typically $30,000 to $60,000 depending on the state. First home buyer concessions are largely exhausted at this level (except NSW, which extends to $1 million). The NSW premium property surcharge starts at $1 million for certain foreign buyers. At this price, the choice of state has a significant financial impact: duty on a $1 million property ranges from about $18,000 in the ACT to $40,000 in NSW.

State comparison matters more

On a $1 million property, stamp duty ranges from approximately $18,000 (ACT, with ongoing higher rates) to $40,000 (NSW). If you are choosing between locations near a state border (e.g., Canberra vs Queanbeyan, Gold Coast vs Tweed Heads), the stamp duty difference can be significant.

Budget for total transaction costs

Stamp duty is the largest government cost, but add conveyancing ($1,500-$3,000), building and pest inspection ($500-$800), and loan establishment fees. On a $1 million purchase, total transaction costs including stamp duty can reach $50,000-$70,000.

Foreign buyer surcharges escalate

At $1 million, foreign buyer surcharges in NSW (9%), VIC (8%), and QLD (8%) add $80,000–$90,000 on top of standard duty. This makes the total duty for a foreign buyer over $120,000 in most eastern states.

Typical buyers: Established professionals upgrading, families in inner suburbs, investors purchasing houses, and interstate movers comparing markets.
