Stamp Duty in Northern Territory
The Northern Territory uses a unique formula-based calculation for properties up to $525,000, then flat rates on the whole value: 4.95% above $525,000 and below $3M, 5.75% from $3M to below $5M, and 5.95% from $5M. The NT does not charge a foreign buyer surcharge.
First Home Buyer Concessions — NT
The NT's first home buyer support is structured differently from other states. There is no first home stamp duty concession. Instead the HomeGrown Territory Grant pays $50,000 to first home buyers who buy or build a new home, with no price cap, for contracts signed between 1 October 2024 and 30 September 2027. It replaced the old $10,000 First Home Owner Grant, and the $10,000 HomeGrown grant for established homes closed to contracts after 30 September 2025.
Additional Information
The $50,000 HomeGrown Territory Grant makes the NT the most generous jurisdiction for first home buyers building new homes. Separately, a house-and-land package bought from a building contractor in a single transaction can be exempt from stamp duty for contracts signed to 30 June 2027 — that exemption is not limited to first home buyers. Otherwise full duty applies.
Property Market
Darwin's median house price of around $550,000–$600,000 means stamp duty costs are lower in absolute terms than most capital cities.
