NT Stamp Duty 2026: Low Duty, Big Grants, No Foreign Surcharge
The Northern Territory offers one of the most buyer-friendly property tax environments in Australia for the 2026–27 financial year. Stamp duty rates are calculated using a formula-based approach for properties up to $525,000 and a tiered scale above that threshold. First-home buyers building or purchasing a new home can access the HomeGrown Territory Grant of $50,000 — the largest first-home grant in the country — with no price cap. The NT, alongside the ACT, imposes no foreign purchaser conveyance duty surcharge, meaning overseas buyers pay the same transfer duty as Australian residents.
The old $10,000 First Home Owner Grant has been replaced by the HomeGrown scheme, and a separate FreshStart grant of $30,000 supports previous homeowners building or buying a new home. This article breaks down the NT duty formula, provides worked examples, explains the HomeGrown and FreshStart grants, and covers the absence of a foreign surcharge.
NT Transfer Duty Rates (2026–27)
The Northern Territory uses a two-part approach to calculating transfer duty. For properties with a dutiable value up to $525,000, duty is computed using a formula rather than fixed brackets. For values above $525,000, a tiered rate structure applies.
Properties valued at $525,000 or below:
The formula, sourced from the Stamp Duty Act 1978 and administered by the Territory Revenue Office, is:
D = (0.06571441 × V²) + 15V
Where V equals the dutiable value divided by 1,000.
To illustrate for a $400,000 property:
- V = 400
- D = (0.06571441 × 160,000) + (15 × 400)
- D = 10,514.31 + 6,000 = $16,514.31
This formula produces a progressive result — duty increases faster as the property value rises, though the effective rate remains modest compared to southern states.
Properties above $525,000:
For dutiable values exceeding $525,000, the NT applies tiered marginal rates that reach approximately 4.95% to 5.95% at the upper brackets. The effective rate on a $700,000 property works out to roughly 4.4%–4.6%, making NT duty competitive with South Australia and significantly cheaper than NSW or Victoria at the same price point.
Worked Examples
Example 1: $350,000 established home (Darwin suburb)
Using the formula: V = 350 D = (0.06571441 × 122,500) + (15 × 350) D = 8,050.02 + 5,250 = $13,300.02
A buyer of a $350,000 property in Darwin or Palmerston would pay approximately $13,300 in transfer duty. This is lower than the equivalent purchase in SA, NSW, or Victoria.
Example 2: $600,000 new home — first-home buyer
For the duty portion above $525,000, tiered rates apply. Total duty on a $600,000 property comes to approximately $27,000–$28,000. The first-home buyer would then receive the $50,000 HomeGrown grant, which more than offsets the entire stamp duty bill, leaving a net positive of roughly $22,000.
Example 3: Foreign buyer, $500,000 property
Formula: V = 500 D = (0.06571441 × 250,000) + (15 × 500) D = 16,428.60 + 7,500 = $23,928.60
Because the NT has no foreign conveyance surcharge, a foreign buyer pays the identical amount — $23,928.60 — with no additional levy.
HomeGrown Territory Grant: $50,000 with No Price Cap
The HomeGrown Territory Grant, replacing the previous $10,000 FHOG, provides $50,000 to first-home buyers building or purchasing a new home in the Northern Territory. Key details for 2026–27:
- Amount: $50,000 — the most generous first-home grant of any Australian jurisdiction.
- Eligibility: Available to first-home buyers who are Australian citizens or permanent residents, purchasing or building a new home. The home must not have been previously occupied or sold as a residence.
- No price cap: Unlike grants in some states that phase out above certain property values, the HomeGrown grant has no maximum purchase price. A first-home buyer purchasing a $1.5 million new home in Darwin would still receive the full $50,000.
- No stamp duty concession: The NT does not provide a separate first-home stamp duty concession or exemption. The HomeGrown grant effectively serves as the primary first-home incentive, and its size means it can fully cover or exceed the stamp duty on many purchases.
FreshStart Grant: For previous homeowners (not first-home buyers) building or purchasing a new home, the NT offers a $30,000 FreshStart grant under similar eligibility criteria. This supports existing residents upgrading or moving within the Territory.
The combined effect is that an NT first-home buyer purchasing a $500,000 new home might pay approximately $23,900 in stamp duty but receive $50,000 from HomeGrown — a net gain of over $26,000 toward their purchase costs.
No Foreign Purchaser Surcharge
The Northern Territory, like the ACT, imposes no foreign purchaser conveyance duty surcharge. When a foreign person, foreign corporation, or trustee of a foreign trust acquires residential property in the NT, the transfer duty payable is exactly the same as for an Australian resident buyer.
This makes the NT an outlier among the states, most of which charge 7%–9% on top of standard rates. For a foreign buyer purchasing a $700,000 Darwin property:
- NT total stamp duty: approximately $30,000 (no surcharge)
- NSW total stamp duty on a comparable purchase: standard duty (~$30,000) + 9% surcharge ($63,000) = ~$93,000
Foreign buyers must still comply with FIRB requirements and pay the federal FIRB application fee, which is separate from territory stamp duty. The FIRB fee starts at $14,100 for properties up to $1 million and increases on a sliding scale.
Frequently Asked Questions
How much is the HomeGrown Territory Grant?
$50,000 for eligible first-home buyers building or purchasing a new home. This is the largest first-home grant in Australia and has no maximum property price cap.
Is there a stamp duty concession for first-home buyers in the NT?
No separate stamp duty concession exists. However, the $50,000 HomeGrown grant exceeds the stamp duty on most purchases, effectively offsetting the duty and providing additional funds.
Do foreign buyers pay extra stamp duty in the NT?
No. The NT does not impose a foreign purchaser conveyance duty surcharge. Foreign and domestic buyers pay the same transfer duty under the same formula and tiered rates.
What is the FreshStart grant?
A $30,000 grant for previous homeowners (not first-home buyers) building or purchasing a new home in the Northern Territory. Eligibility criteria are similar to HomeGrown but targeted at existing residents.
How does NT stamp duty compare to the rest of Australia?
On a $500,000 property, NT duty of approximately $23,900 is comparable to Queensland and cheaper than NSW, Victoria, and SA. The combination of moderate duty rates, the $50,000 HomeGrown grant, and no foreign surcharge makes the NT one of the most attractive jurisdictions for both first-home buyers and foreign investors.
