What are the stamp duty rates in the Northern Territory?
These are the rate tables published by the Territory Revenue Office and the legislation behind them, set out as data with the date of each source page. The calculator above and every worked figure on this page use these scales, so you can check any result against them by hand.
Stamp duty on a conveyance of land, Stamp Duty Act 1978 (NT), Schedule 1, consolidated version read on 28 October 2026. The page shows no separate effective date. V is the value divided by 1,000. Duty keeps the cents the formula gives.
| Value of the property | Stamp duty |
|---|---|
| Up to $525,000 | D = (0.06571441 × V × V) + (15 × V), where D is the duty in dollars |
| Over $525,000 to under $3,000,000 | 4.95% of the value |
| $3,000,000 or more but less than $5,000,000 | 5.75% of the value |
| $5,000,000 or more | 5.95% of the value |

How much is stamp duty on a home in the Northern Territory?
On a $500,000 property, Northern Territory stamp duty is $23,928.60. On $700,000 it is $34,650, and on $1,000,000 it is $49,500. The amount comes from the scale in Schedule 1 of the Stamp Duty Act 1978. A first home buyer pays the same, unless the purchase qualifies for the house and land package exemption.
The common prices table above runs nine prices through the same engine as the calculator.

How is stamp duty calculated in the Northern Territory?
Up to $525,000 the Act uses a formula: divide the value by 1,000 to get V, then duty is 0.06571441 times V times V, plus 15 times V. For $500,000, V is 500 and duty is $23,928.60. Above $525,000 duty is a flat percentage of the whole value.
The formula is built so the two parts meet. Duty rises smoothly up to $525,000, then switches to 4.95% of the value, rising to 5.75% from $3,000,000 and 5.95% from $5,000,000. There are no bands with base amounts, as in most other states.

Why does Northern Territory stamp duty become a flat percentage above $525,000?
Because Schedule 1 of the Stamp Duty Act sets 4.95% of the whole value for properties over $525,000 and under $3,000,000. A $600,000 property pays $29,700, and $800,000 pays $39,600. Duty goes up by 4.95% of each extra dollar, so the percentage on the whole price stays level.

Do first home buyers pay stamp duty in the Northern Territory?
Yes. The Northern Territory has no first home buyer stamp duty concession, so a first home buyer pays the same duty as anyone else: $29,700 on $600,000. The only duty relief is the house and land package exemption, which is not limited to first home buyers and has strict conditions.
Our calculator shows $0 only when you confirm the purchase is a qualifying house and land package. It never assumes that a new home qualifies.

What is the Northern Territory house and land package exemption?
It removes stamp duty on a qualifying new detached home, with no value cap and no means test. The buyer signs one transaction with a building contractor for the land and the home, the contract falls between 1 July 2022 and 30 June 2027, and a buyer must live in the home within 12 months.
On a $700,000 package, the exemption means the $34,650 of duty is not payable. Ask the Territory Revenue Office to confirm that your contract qualifies before you sign.
- One single transaction with a building contractor covers both the land and the build.
- The home is a new detached home.
- The builder bought the land from a developer and paid duty on it.
- The contract is dated from 1 July 2022 to 30 June 2027.
- There is no value cap and no means test.
- You must live in the home within 12 months, for at least 6 continuous months.

What does not qualify for the Northern Territory house and land exemption?
Anything that is not a single transaction for a new detached home with a building contractor. An apartment is not a detached home. Buying a block and then signing a separate build contract is two transactions. Contracts outside 1 July 2022 to 30 June 2027 are also outside the exemption.
The exemption page says the builder must have bought the land from a developer and paid duty on it. A purchase that does not match every condition on the Territory page may be charged full duty, so check the page and the Territory Revenue Office before you sign.

Is stamp duty different for a new home, an established home or vacant land in the Northern Territory?
The rate scale is the same. Duty depends on the value of the property, and we found no separate scale for new homes, established homes or vacant land. The difference is the exemption: only a qualifying house and land package from a building contractor can have the duty removed.
For an established home at $800,000 the duty is $39,600. For a qualifying new house and land package at the same price the duty payable is nil.

Do investors pay more stamp duty than home buyers in the Northern Territory?
We found no separate investor scale in Schedule 1. The scale on this page applies to the value of the property, so a $900,000 purchase costs $44,550 whether you live in it or rent it out. The house and land exemption does need you to live in the home.

When do I have to pay stamp duty in the Northern Territory?
As a general rule, within 60 days of the date the contract is first signed. The Territory Revenue Office lodgement form says documents must be lodged and the duty paid within 60 days of the date of first execution. Ask the Territory Revenue Office or your conveyancer about the date that applies to your contract.
Duty is assessed on the value of the property, so the figure you owe is the one in the calculator above for your price.

Can stamp duty be added to the loan in the Northern Territory?
The Territory Revenue Office assesses duty. It does not say how a buyer funds it. Whether a lender will lend towards duty is the lender's decision, based on its own policy and your application. The duty is still owed to the Territory by its due date.

Is there a first home owner grant in the Northern Territory?
Yes. HomeGrown Territory pays $50,000 to first home buyers who buy or build a new home, on contracts from 1 October 2024 to 30 September 2027. It is a grant, so it does not change the stamp duty on this page. The NT Government page says there is no cap on the build or purchase price.
The home must never have been lived in or sold as a place of residence, and you must live in it for at least 12 months. Other conditions are on the NT Government page, so read it before you sign.

What else should I check with the Territory Revenue Office?
Check the Territory Revenue Office for anything this page does not list. This page covers the Schedule 1 scale, the house and land package exemption and the HomeGrown Territory grant. It does not list any other general home buyer concession or a foreign buyer surcharge, because we did not read a Territory page for either.

What are the common mistakes with Northern Territory stamp duty?
The main one is assuming a first home buyer concession exists, because most other states have one. Others are assuming any new home gets the exemption, and signing separate land and build contracts, which leaves two transactions and can put the purchase outside the exemption.
- The exemption is for a single transaction with a building contractor, not for any new home.
- An apartment is not a detached home.
- The contract date must fall between 1 July 2022 and 30 June 2027.
- You must live in the home within 12 months, for at least 6 continuous months.
