Northern Territory stamp duty on property is worked out with a formula for homes under A$525,000 and a flat 4.95% of the whole price from A$525,000 to under A$3 million, then 5.75% from A$3 million and 5.95% from A$5 million. That makes the duty A$29,700 on a A$600,000 home and A$44,550 on a A$900,000 home. The NT has no general first home buyer stamp duty concession, but first home buyers of new homes can get the A$50,000 HomeGrown Territory Grant and some house and land packages are exempt.
Stamp duty is one of the largest upfront costs of buying in Darwin, Palmerston or Alice Springs, and the Territory’s formula is less intuitive than the bracket tables used in most states. This guide sets out the current rates, shows the arithmetic a stamp duty calculator NT buyers use would run, explains the grants and the one remaining duty exemption, and covers when duty is paid and what else you pay the Land Titles Office.
Stamp duty, also called transfer duty or conveyance duty, is a one-off tax the buyer pays when land or a home changes hands. In the Territory it is charged under the Stamp Duty Act 1978 and administered by the Territory Revenue Office. The version of the Stamp Duty Act in force at 1 July 2025 sets the dutiable value as the greater of the price paid and the unencumbered value of the property, so buying below market value from a relative does not reduce the duty.
Unlike the ACT or Queensland, the NT does not run a separate cheaper scale for owner-occupiers. Investors, owner-occupiers and first home buyers all start from the same rates, and help for first home buyers comes mainly through grants paid after settlement rather than through a reduction in duty.
The Territory Revenue Office publishes the conveyance duty formula and percentage bands in its information sheet on stamp duty on business property (I-SD-002), which uses the same rate schedule. That sheet was last updated in 2019, so we cross-checked it against two current comparison sites, Money.com.au and Compare the Market, both of which list the same figures. A review of the 2026-27 state and territory budgets by King and Wood Mallesons lists no NT stamp duty changes, so these rates continue to apply in 2026.
| Dutiable value | Duty payable |
| Less than A$525,000 | D = (0.06571441 x V squared) + 15V, where V is the dutiable value divided by 1,000 and D is the duty in dollars |
| A$525,000 to A$2,999,999 | 4.95% of the total dutiable value |
| A$3,000,000 to A$4,999,999 | 5.75% of the total dutiable value |
| A$5,000,000 or more | 5.95% of the total dutiable value |
Two features stand out. Above A$525,000 the percentage applies to the whole price, not just the part above the threshold. And because the formula and the 4.95% rate meet at exactly the same figure (A$25,987.50 at A$525,000), there is no jump at that point. There is a jump at A$3 million: on our calculation, duty on A$2,999,999 is A$148,499.95, while duty on A$3,000,000 is A$172,500.
The formula looks intimidating, but it is only three steps. Divide the price by 1,000 to get V. Square V and multiply the result by 0.06571441. Then add 15 times V. The squared term means the effective rate climbs smoothly as the price rises, from roughly 3.5% at A$300,000 to just under 5% near A$525,000.
| Price | V | 0.06571441 x V squared | 15 x V | Duty | Effective rate |
| A$300,000 | 300 | A$5,914.30 | A$4,500.00 | A$10,414.30 | 3.47% |
| A$450,000 | 450 | A$13,307.17 | A$6,750.00 | A$20,057.17 | 4.46% |
| A$500,000 | 500 | A$16,428.60 | A$7,500.00 | A$23,928.60 | 4.79% |
These figures were calculated with a script from the published formula and are shown to the cent. The Territory Revenue Office assessment is the final word on any rounding.
Above A$525,000 the sum is simple: multiply the full dutiable value by the band’s percentage. That is exactly what any online stamp duty calculator NT buyers use does.
| Purchase price | Band | Arithmetic | Stamp duty |
| A$600,000 | A$525,000 to A$2,999,999 | A$600,000 x 4.95% | A$29,700 |
| A$900,000 | A$525,000 to A$2,999,999 | A$900,000 x 4.95% | A$44,550 |
| A$1,500,000 | A$525,000 to A$2,999,999 | A$1,500,000 x 4.95% | A$74,250 |
The same amounts apply whether you are a first home buyer, an owner-occupier or an investor, unless the purchase qualifies for the house and land package exemption described below. If you are buying a new home as a first home buyer, the A$50,000 HomeGrown Territory Grant would more than cover the duty on the A$600,000 and A$900,000 examples, although the grant is paid separately and does not reduce the duty itself.
First home buyer stamp duty NT rules are simple: there is currently no general stamp duty concession or exemption for first home buyers in the Territory. Both Money.com.au and Compare the Market state that first home owners pay the full duty, and the government’s home owner assistance page lists grants and a single house and land exemption rather than a first home duty discount. Help comes through the HomeGrown Territory Grants instead.
According to the NT Government grant page, the HomeGrown Territory Grant offers A$50,000 to first home buyers who buy or build a new home. Key rules:
The government’s established home page explains that the HomeGrown Territory Grant extended the First Home Owner Grant to A$10,000 for established homes, but only for contracts signed between 1 October 2024 and 30 September 2025. That window has closed, so first home buyers of established homes signing in 2026 receive neither a grant nor a duty concession. Buyers who signed in the window can still apply within 12 months of settlement.
Existing home owners who buy or build a new home can apply for the A$30,000 FreshStart New Home Grant, which runs alongside the HomeGrown grant until 30 September 2027 (applications until 31 December 2027). The two grants cannot be combined. A good mortgage broker in Darwin can tell you whether a lender will release a grant early to help with your deposit, which the government page says is possible subject to normal approval.
| Scheme | Amount | Who it is for | Contract window |
| HomeGrown Territory Grant | A$50,000 | First home buyers of a new home | 1 Oct 2024 to 30 Sep 2027 |
| FreshStart New Home Grant | A$30,000 | Existing owners buying or building new | Until 30 Sep 2027 |
| Established home grant (FHOG extension) | A$10,000 | First home buyers of an established home | 1 Oct 2024 to 30 Sep 2025 (closed) |
| House and Land Package Exemption | Full duty exemption | Any eligible owner-occupier buying a qualifying package | 1 Jul 2022 to 30 Jun 2027 |
The only current stamp duty exemption for home buyers is the House and Land Package Exemption. The NT Government exemption page sets these conditions:
You apply by completing the form and emailing it with supporting documents to the Territory Revenue Office, or giving it to your conveyancer or lawyer. Because the exemption ends with contracts signed on 30 June 2027, timing matters for anyone planning a package build.
Several states charge foreign purchasers an extra duty surcharge: NSW’s surcharge purchaser duty is 9% and Queensland’s additional foreign acquirer duty is 8%. Compare the Market states that the NT does not impose an additional stamp duty surcharge on foreign buyers, and the 2026-27 budget review cited above lists no new NT surcharge. Foreign buyers therefore pay the same Northern Territory stamp duty as locals, although Commonwealth foreign investment rules may still apply. Investors also pay the standard rates, as there is no separate investor scale.
Under section 9 of the Stamp Duty Act (as in force at 1 July 2025), a dutiable instrument such as a transfer must be lodged within 60 days after it is first executed, and duty must be paid on or before the last day allowed for lodgement unless a notice of assessment sets a later date. In practice, most purchases are handled by a conveyancer or lawyer.
| Step | Timing | Who does it |
| Contract signed | Exchange | Buyer and seller |
| Transfer executed and lodged for assessment | Within 60 days of first execution | Your conveyancer or lawyer |
| Duty paid | By the lodgement deadline, or under Conveyance by Return by the 15th of the following month | Usually your conveyancer from settlement funds |
| Transfer registered | After duty is paid | Land Titles Office |
The Territory Revenue Office’s stamp duty page explains that approved conveyancers and solicitors can use Conveyance by Return, paying duty monthly with payment due by the 15th of the following month. The government’s guide to transferring land lists assessing and paying duty as the step before lodging the transfer with the Land Titles Office. Your conveyancer in Darwin will normally handle the assessment, payment and any exemption application for you.
The Land Titles Office charges a flat fee to register each document. The NT Government pages for registering a transfer and lodging a mortgage or discharge currently list these fees:
| Land Titles Office item | Fee |
| Registration of a transfer | A$181 |
| Registration of a mortgage | A$181 |
| Discharge of a mortgage (usually a seller cost) | A$181 |
A buyer with a home loan therefore pays A$362 in registration fees on top of duty. The mortgage page notes that other fees may apply when lodging online through eConveyancing, and lenders charge their own fees. Moving costs are worth budgeting early too, especially for interstate moves into the Top End: the removalists in Darwin list is a useful place to start.
Queensland publishes a general transfer duty scale on the Queensland Revenue Office rates page, with separate home and first home concession rates for owner-occupiers. The figures below compare NT duty with Queensland’s general rate (the rate investors pay) and were calculated from each jurisdiction’s published rates.
| Purchase price | NT stamp duty | Queensland general rate |
| A$450,000 | A$20,057.17 | A$14,175 |
| A$600,000 | A$29,700 | A$20,025 |
| A$900,000 | A$44,550 | A$33,525 |
| A$1,500,000 | A$74,250 | A$66,775 |
| Foreign buyer surcharge | None reported | 8% additional foreign acquirer duty |
The NT is dearer than Queensland’s general scale at every price shown, and Queensland owner-occupiers can pay less again through home concessions. The NT’s offset is its grants and the absence of a foreign buyer surcharge.
A$500,000 is under A$525,000, so the formula applies. V is 500. Squaring 500 gives 250,000, multiplied by 0.06571441 that is A$16,428.60. Add 15 x 500, which is A$7,500, and the duty is A$23,928.60, an effective rate of about 4.79%. The same figure applies to first home buyers, owner-occupiers and investors unless the house and land package exemption applies.
Yes, in most cases. The Territory has no general first home buyer stamp duty concession, so first home buyers pay the standard rates. The main help is the A$50,000 HomeGrown Territory Grant for new homes contracted between 1 October 2024 and 30 September 2027. A buyer of a qualifying house and land package from a builder can also be exempt from duty, regardless of whether it is their first home.
Yes. The NT Government publishes a land or property transfer stamp duty calculator on nt.gov.au, and banks and comparison sites offer their own. You enter the purchase price or unencumbered value, whichever is greater. The official calculator estimates duty for buyers who are not eligible for a concession, so if you are buying a house and land package, check the exemption separately.
The transfer duty NT buyers pay is simply another name for stamp duty on property. In the Territory the tax is charged under the Stamp Duty Act 1978 on the conveyance of land, using a formula below A$525,000 and flat rates of 4.95%, 5.75% and 5.95% of the whole value above that. The buyer pays it, normally through their conveyancer, before the transfer is registered.
According to Compare the Market, the NT does not impose an additional stamp duty surcharge on foreign buyers, which sets it apart from NSW and Queensland. Foreign buyers pay the standard Northern Territory stamp duty rates. They may still need Commonwealth foreign investment approval, and should confirm the current position with the Territory Revenue Office before signing.
The Stamp Duty Act requires a dutiable instrument to be lodged within 60 days after it is first executed, with duty paid by that deadline unless an assessment notice sets a later date. Conveyancers using Conveyance by Return pay duty to the Territory Revenue Office by the 15th of the following month. Duty must be paid before the Land Titles Office registers the transfer.
Multiply the full dutiable value by the rate for its band: 4.95% from A$525,000 to under A$3 million, 5.75% from A$3 million to under A$5 million and 5.95% from A$5 million. A A$750,000 home therefore attracts A$37,125 in duty. Unlike the NSW and Queensland scales, the rate applies to the whole price rather than only the amount above the threshold.
