NT stamp duty rates (2026–2027)
For a dutiable value up to $525,000, the NT uses a formula rather than rate bands:
D = 0.06571441 × V² + 15V
where D is the duty and V is the dutiable value divided by 1,000. Above $525,000, flat rates apply to the whole value:
| Dutiable value | Duty payable |
|---|---|
| $525,000 – $3,000,000 | 4.95% of the total value |
| $3,000,000 – $5,000,000 | 5.75% of the total value |
| $5,000,000 and above | 5.95% of the total value |

NT Stamp Duty FAQs
How much is stamp duty on a $700,000 home in NT?
Standard stamp duty on a $700,000 established home in NT is $34,650. First home buyers and owner-occupiers usually pay less — set those options in the calculator above for your figure.
When do you pay stamp duty in NT?
Stamp duty is a one-off cost paid around settlement, not an annual tax. Your conveyancer usually pays it to Territory Revenue Office as part of settlement, so budget for it on top of your deposit.
Is stamp duty charged on the price or the property value in NT?
On the dutiable value — the greater of the purchase price and the property's market value. For a normal arm's-length sale that's just the contract price; a below-market or gifted transfer is assessed at market value.
How is stamp duty calculated in the Northern Territory?
For a dutiable value up to $525,000, the NT uses a formula — D = 0.06571441 × V² + 15V, where V is the price divided by 1,000 — rather than rate bands. Above $525,000, flat rates of 4.95% to 5.95% apply to the whole value.
What help is there for first home buyers in the NT?
The House and Land Package Exemption removes stamp duty entirely, with no value cap or means test — but it requires a contract with a registered building practitioner covering the land and a detached new home. Plain vacant land and new apartments do not qualify, and neither do established homes. First home buyers of a new home may also receive the $50,000 HomeGrown Territory Grant for an eligible new-home transaction.

Each state charges its own duty on the property within its borders — compare them all on the stamp duty calculator hub.
