How NT stamp duty is calculated (2026-27)
Rates checked 15 Oct 2026 against the Territory Revenue Office and NT Treasury Budget Paper 2.
Northern Territory stamp duty on a property transfer is charged on the dutiable value, the higher of the price and the unencumbered value. Up to $525,000 it's worked out with a formula from the Territory Revenue Office; above that it's a flat percentage of the whole value. The same rates apply to homes and investments.
| Dutiable value | Stamp duty |
|---|---|
| Up to $525,000 | (0.06571441 × V²) + 15V, where V is the value ÷ 1,000 |
| $525,001 – under $3 million | 4.95% of the value |
| $3 million – under $5 million | 5.75% of the value |
| $5 million and over | 5.95% of the value |
Worked example: a $500,000 home: V = 500, so (0.06571441 × 250,000) + (15 × 500) = 16,428.60 + 7,500 = $23,929. A $750,000 home is 4.95% × $750,000 = $37,125.
House and land package exemption: buy a new detached home and its land from a building contractor in one contract, signed between 1 July 2022 and 30 June 2027, and you pay no stamp duty. It isn't means tested, there's no price cap and you don't need to be a first home buyer, but at least one buyer must live in it for 6 continuous months, starting within 12 months of completion. The NT has no other first home buyer duty concession and no foreign buyer surcharge.

$23,929, from the Territory Revenue Office formula (0.06571441 × V²) + 15V with V = 500. It's the same for a first home buyer, unless it's a house and land package, which pays $0.

Yes, on an established home: $23,929 on $500,000 and $37,125 on $750,000. The only home buyer exemption is for a house and land package bought from a builder in one contract, signed by 30 June 2027, which any buyer who lives in it can use.
