What is stamp duty?
Long story short
Stamp duty in NT can cost tens of thousands
It’s a one-off tax on property purchases calculated based on the value of the home.
First-home buyers don’t get a stamp duty concession in NT, but as at January 2026, they can score a grant of up to $50,000
Eligible first-home buyers may access the HomeGrown Territory grant of $50,000 for buying or building a new home, or $10,000 for buying an established home (for eligible contracts).
Homebuying can hit you with extra costs
And they can add up fast! Think $1,800 for conveyancing, around $600 for building and pest checks, and $100–200 for mortgage registration fees.
What is stamp duty?
Stamp duty – a tax you have to cough up when you’re sealing the deal on a home in the Northern Territory (and pretty much everywhere else).
Stamp duty is just one of the considerations when diving into the home-buying game. It’s not a fixed percentage or a straight-up flat fee; it’s a sliding-scale kind of deal. The big player here is the ‘dutiable value’, which is just a fancy way of saying the property’s worth – be it the purchase price or its market value, whichever hits heavier on the wallet.
Where your place is planted and what you’re planning to do with it can also throw some extra spice into the mix, shaping up how much of that stamp duty cash you’ll be forking over.
If you want to find out how much stamp duty you might need to pay for a property, you can use our calculator below.
How much is stamp duty in the NT?
In the NT, they keep things relatively simple by splitting their stamp duty game into four price brackets.
- If your dream house falls under $525,000, there’s a formula to figure out your stamp duty.
- If your spot is rocking a price tag higher than $525,000, they’re ditching the formula and pulling out the percentage calculator. Your stamp duty bill is a percentage of your property.
To make life a bit easier, we’ve got the details neatly wrapped up in a table below. It’s the cheat sheet for stamp duty in the NT – showing you the lowdown on how the dollars stack up based on the government’s script.
Stamp duty thresholds and amounts in the NT
| Property value | Stamp duty payable |
| Up to $525,000 | D = (0.06571441 x V2) + 15V where: D is the duty (expressed in dollars) V is 1/1,000 of the dutiable value (expressed in dollars) |
| $525,001 to $2,999,999 | 4.95% of the dutiable value |
| $3,000,000 to $4,999,999 | 5.75% of the dutiable value |
| $5 million or more | 5.95% of the dutiable value |

Say you’re eyeing a property valued at $500,000. Based on the table, the stamp duty is $23,928.60.
How to calculate stamp duty for a $500,000 property
V is $500,000 x 0.001 = $500
15V = $7,500
V2 = $250,000
D is (0.06571441 x $250,000) + $7,500 = $23,928.60
What property types does stamp duty apply to in NT?
In the top end, you’ll have to pay for stamp duty if you’re buying:
- a home
- a block of land
- a business property.
Some leases may also attract duty if a premium is paid in addition to, or instead of, rent.
Helpful tip
It’s worth having a chat with your mortgage broker, conveyancer, or solicitor about how much stamp duty you might need to pay – and whether you’re eligible for any exemptions or grants. Stamp duty is no pocket change, so when you’re planning to buy a property, it’s a good idea to factor it into your budget to make sure you’re not caught off guard when it’s time to sign the dotted line.

Do first home buyers have to pay stamp duty in NT?
Most Aussies wanting to buy a property in the Northern Territory generally have to pay stamp duty. However, you might be eligible for some exemptions and grants in the Territory.
House and Land Package Exemption (HLPE)
You may be eligible for this stamp duty exemption if you’re buying a house and land package from a builder in one single deal, and you sign the contract until 30 June 2027.
The contract needs to say that the building contractor will either:
- build a brand‑new detached home on the land
- finish building one that’s already partly done
- transfer the ownership of a completed detached new home sitting on that land to you.
The builder also has to have bought the land from a developer and already paid stamp duty on it.
HomeGrown Territory Grant
The HomeGrown Territory Grant provides financial support to eligible first-home buyers in the Northern Territory.
Eligible buyers can receive $50,000 when buying or building a new home, or $10,000 when buying an established home, subject to eligibility criteria and contract dates.
The grant builds on the existing First Home Owner Grant, increasing the available support during the HomeGrown Territory period.
There are a few other requirements that must be met:
- You’re an individual buying a property for the first time in Australia.
- You’ve signed a purchase contract sometime between 1 October 2024 and 30 September 2026.
- At least one of the applicants is over 18 years old.
- At least one of the applicants is either an Australian citizen or permanent resident.
- You’ll live in your property for at least 12 months after settlement.
FreshStart New Home grant
If you’re planning to buy or build a new home in the NT, then you could get a windfall of $30,000 through the FreshStart New Home Grant. Applicants who are owner–builders or planning to buy off the plan are eligible for this grant.
There are other eligibility requirements to keep in mind:
- You’ve signed a purchase contract anytime from 1 October 2024 to 30 September 2026.
- You’re an individual (no companies or trusts).
- One of the applicants is at least 18 years old.
- One of the applicants is an Aussie citizen or permanent resident.
- You’re going to nest in your new home for at least 12 months within a year of purchase or once your home’s completely built.
- You’ll apply by 31 December 2026.
While this grant isn’t just for first-time homebuyers, it’s worth keeping in mind. Because let’s face it, who doesn’t love a bit of extra cash in the back pocket!
Are there other stamp duty exemptions or concessions in the NT?
There are a few instances when you can also be exempt from paying stamp duty in the Territory, including:
- inheriting a property from a deceased estate
- transferring to joint names of spouses
- transferring an interest in farm from one family member to another.
What other fees might I need to pay besides stamp duty in the NT?
Aside from stamp duty, it’s worth putting a bit extra aside for the other bits and pieces so you’re not blindsided with other admin-related expenses.
- Conveyancing and legal fees: You’ll need a conveyancer or solicitor to sort out all the legal stuff – contracts, lodging documents, the works. Definitely not a DIY job. You might be looking at about $1,800, but it can change depending on how tricky things are and who you go with.
- Building and pest inspection: Before you sign on the dotted line, it’s a good idea to get the place checked for structural issues and nasties like termites. Doing this could save you a heap later. A combined building and pest inspection can cost a few hundred dollars, depending on the property and provider.
- Mortgage registration fee: This one’s a government charge for registering your lender’s mortgage on the property title. The land titles office collects it, and it varies by state. It’s worth budgeting roughly $100–200, depending on where you live.
- Loan application fee: Banks often slug you with a fee to set up your home loan. Some lenders charge a loan application/establishment fee. Some waive it, but not always.
Frequently asked questions
When is stamp duty payable in the NT?
Your stamp duty payment will be due within 60 days of your property purchase. One thing to keep in mind – don’t snooze on the payment. If you’re late to the party, they might hit you with penalty tax and interest. Nobody wants that extra bill baggage!
Do foreign buyers pay more stamp duty in the NT?
Unlike many states, the NT does not currently publish a foreign purchaser stamp duty surcharge — foreign purchasers generally pay the same stamp duty rates (check with the Territory Revenue Office for your circumstances).
Can I get a home loan that covers stamp duty?
This might sound like the ideal way to start your new mortgage, but whether this is possible all depends on the lender. Check with your lender to see if they’re willing to increase the amount of your loan to cover it.
Is stamp duty tax deductible in the NT?
Stamp duty isn’t something you can claim back at tax time – bit of a bummer, we know. But here’s the silver lining: when you eventually sell, that stamp duty counts towards what you paid for the place. So if you make a profit and your sale is not exempt from capital gains tax, it can help shave down the CGT you’d otherwise cop.
