Calculate Northern Territory stamp duty on conveyances for owner-occupiers, investors, and first home buyers using current Territory Revenue Office rates.
NT stamp duty on conveyances is administered by the Territory Revenue Office under the Stamp Duty Act 1978. The NT uses a single graduated formula rather than discrete brackets: rates rise smoothly with the dutiable value, capping out at 5.95% above $5 million. The duty is charged on the dutiable value — usually the contract price.
NT uses the following bracket structure for the standard duty rate:
| Dutiable value | Standard rate |
|---|---|
| $0 – $525,000 | D = (0.06571441 × V²) + 15V (V in thousands) |
| $525,001 – $3,000,000 | 4.95% of dutiable value |
| $3,000,001 – $5,000,000 | 5.75% of dutiable value |
| Above $5,000,000 | 5.95% of dutiable value |
The Northern Territory does not offer a separate owner-occupier "home concession" — owner-occupiers and investors pay the same standard rates on established dwellings. The only owner-occupier relief is the first home buyer discount on new builds (capped at $50,000) and the First Home Owner Grant (separate cash grant). Like Tasmania, the NT does not currently levy a foreign buyer surcharge.
The Northern Territory currently offers a stamp duty discount of up to $50,000 for first home buyers purchasing a new home, a house and land package, or vacant land where a new home will be built. There is no full exemption — the discount reduces the duty payable by up to $50,000 (capped at the actual duty liability). For established homes there is no first home buyer concession; first home buyers pay full standard rates. To qualify you must be eligible for the First Home Owner Grant and lodge the discount claim through your conveyancer.

Northern Territory does not currently levy a foreign buyer surcharge on residential property purchases. Foreign buyers pay only the standard stamp duty on conveyances rates with no additional surcharge — making Northern Territory one of the few Australian jurisdictions where overseas buyers pay no extra duty.
| Scenario | Investor | Owner-occupier | First home buyer |
|---|---|---|---|
| $520,000 property | $9,478 | $9,478 | $0 (FHB exemption) |
| $700,000 property | $13,978 | $13,978 | $13,978 (established) |
| $1,000,000 property | $21,478 | $21,478 | $21,478 (established) |
Estimates use Territory Revenue Office 2025–26 stamp duty on conveyances rates. Always confirm the exact figure with your solicitor or conveyancer before settlement — these calculations do not account for off-the-plan concessions, pensioner concessions, or other state-specific reliefs that may apply to your situation.
Need to calculate stamp duty for another state? Use our all-states stamp duty calculator, which covers NSW, VIC, QLD, SA, WA, TAS, ACT, and NT in a single tool. Each state has different rates, thresholds, and concessions — Northern Territory is one of the few jurisdictions without a foreign buyer surcharge.
NT stamp duty on conveyances is charged by the Territory Revenue Office on the dutiable value of any property purchase. The NT uses a single graduated formula rather than discrete brackets — rates rise smoothly with the dutiable value, capping out at 5.95% above $5 million. Owner-occupiers and investors pay the same standard rates on established dwellings.
First home buyers buying new homes, house and land packages, or vacant land where a new home will be built can claim a stamp duty discount of up to $50,000. There is no full exemption — the discount reduces the duty payable by up to $50,000. For established homes there is no first home buyer concession.
NT stamp duty is payable within 60 days of the dutiable transaction. Your conveyancer normally pays the Territory Revenue Office at settlement using funds drawn from your loan and deposit. Late payment attracts interest and penalty tax under the Taxation Administration Act (NT).
No. The Northern Territory does not currently levy a foreign buyer surcharge on residential property purchases. Like Tasmania, this makes the NT notably cheaper for foreign buyers than NSW, VIC, QLD, SA, WA, or the ACT.
The NT formula (D = 0.06571441 × V² + 15V for purchases under $525,000) produces a smooth graduated curve rather than the bracket-based steps used in other states. The practical effect is similar to a tiered system, but the duty changes by cents (not dollars) as the price changes — eliminating the small jumps at bracket boundaries that other states have.
No. Stamp duty paid on an investment property in the NT is not immediately deductible against rental income. It is added to the cost base of the property and reduces capital gains tax when the property is later sold. Owner-occupiers cannot deduct stamp duty at all.
