NT stamp duty rates 2026
The Territory does not use bands with a base amount. Up to $525,000 the duty comes from a formula, so the effective rate climbs smoothly with the price. Above $525,000 a flat percentage applies to the whole value: 4.95% up to $3 million, then 5.75% and 5.95% (Territory Revenue Office). The formula and the flat rate meet at $525,000, so there is no jump at the line.
A $500,000 home is under $525,000, so the formula applies: V is 500, and 0.06571441 × 500² + 15 × 500 comes to $23,929. A $750,000 home is over $525,000, so 4.95% applies to the whole value: $37,125, an effective rate of 4.95%.
| Dutiable value | Duty |
|---|---|
| Up to $525,000 | (0.06571441 × V²) + 15V, where V is the value divided by 1,000 |
| $525,001 to under $3,000,000 | 4.95% of the whole value |
| $3,000,000 to under $5,000,000 | 5.75% of the whole value |
| $5,000,000 or more | 5.95% of the whole value |

First home buyer thresholds in the NT
The Northern Territory has no first home buyer stamp duty concession: a first home buyer pays $37,125 on a $750,000 home, the same as anyone else (Territory Revenue Office).
The help comes as a grant. The HomeGrown Territory grant pays $50,000 to an eligible first home buyer who buys or builds a new home, for contracts signed between 1 October 2024 and 30 September 2027. The $10,000 grant for an established home applied to contracts signed from 1 October 2024 to 30 September 2025 and has closed.
A grant does not reduce the duty; it arrives as cash toward the purchase. Our NT first home buyer guide covers the eligibility rules.
NT stamp duty concession rates
The Territory has no duty concessions for home buyers. Its first home help is paid as grants:
| Grant | Amount | Contracts signed |
|---|---|---|
| New home, bought or built | $50,000 | 1 October 2024 to 30 September 2027 |
| Established home | $10,000 | 1 October 2024 to 30 September 2025 (closed) |
Foreign buyer surcharge in the NT
The Northern Territory does not charge a foreign purchaser stamp duty surcharge. A foreign buyer pays the same duty as a local buyer at the same price, which sets the Territory apart from every state (Territory Revenue Office).
Exemptions: who pays less or nothing in the NT
- First home buyers. No duty concession. The HomeGrown Territory grant pays $50,000 toward a first new home instead.
- Everyone else. One schedule for all buyers: $37,125 on a $750,000 home.
Each one has its own eligibility test, set out by the Territory Revenue Office. A concession you are not entitled to can be reassessed with interest and penalties, so confirm it before settlement.
What is stamp duty in the NT?
Stamp duty, called conveyance duty in the legislation, is the tax the Northern Territory charges when property changes hands. For most buyers it is the largest upfront government cost after the deposit itself.
The buyer pays it, not the seller. It is calculated on the dutiable value, usually the purchase price, and it falls due at settlement. Because there is no first home concession and no owner-occupier rate, every buyer at a given price pays the same duty, so the rate table below is the whole story.
When do you pay stamp duty in the NT?
The buyer pays stamp duty, not the seller, and it is normally paid at settlement. Your conveyancer or solicitor works out the figure, lodges the transaction with the Territory Revenue Office and pays the duty from the settlement funds, so you rarely deal with the revenue office yourself.
Budget for it as cash on top of your deposit from the start: on a $750,000 home in the NT it is $37,125 for an owner-occupier. Late payment can attract interest, which is one more reason the timing sits with your conveyancer. Our conveyancing guide explains who does what at settlement.

Common questions
How much is stamp duty on a $800,000 house in the NT?
$39,600. Above $525,000 the Territory Revenue Office charges a flat 4.95% of the whole value, so an $800,000 home costs 4.95% of $800,000. First home buyers, owner-occupiers, investors and foreign buyers all pay that figure, because the NT has no concession and no foreign surcharge. A first home buyer building new may get the $50,000 HomeGrown Territory grant.
Do first home buyers pay stamp duty in the NT?
Yes, at the full rate: $23,929 on a $500,000 home and $37,125 on $750,000 (Territory Revenue Office). The NT helps first home buyers with grants instead: $50,000 toward a new home for contracts signed from 1 October 2024 to 30 September 2027. The $10,000 established-home grant closed to contracts after 30 September 2025.
How do I avoid paying stamp duty in the NT?
On a normal purchase you cannot: the Territory has no first home, owner-occupier or foreign-buyer variations, so everyone pays the same schedule, $37,125 on $750,000 (Territory Revenue Office). A first home buyer choosing a new home can offset most of it with the $50,000 HomeGrown Territory grant, for contracts signed by 30 September 2027.
When do you pay stamp duty in the NT?
Normally at settlement. Your conveyancer or solicitor calculates the stamp duty, lodges it with the Territory Revenue Office and pays it out of the settlement funds, so the money has to be ready on the day on top of your deposit. On a $750,000 home in the NT that is $37,125 for an owner-occupier. Pay late and interest can be charged, which is why the conveyancer handles the timing.
Does the NT charge a foreign buyer stamp duty surcharge?
No. The Northern Territory is one of only two places in Australia, with the ACT, that does not add a foreign purchaser surcharge to duty. A foreign buyer pays the same $37,125 on a $750,000 home as a local buyer, where NSW would add 9% and Victoria and Queensland 8% (Territory Revenue Office; state revenue offices, checked 30 September 2026).
