Quick answer: NT stamp duty on a $500,000 property is approximately $23,929. The NT does not offer first home buyer stamp duty exemptions (unique in Australia). Instead, first home buyers get $80,000 in cash grants ($50K HomeGrown + $30K FreshStart) — the highest in Australia. The House and Land Package Exemption (HLPE) gives full stamp duty exemption for packages bought as a single contract. Building separately saves $20,000–$30,000 in stamp duty. NT has no foreign buyer surcharge and no land tax. Updated April 2026 based on Territory Revenue Office data.
“Northern Territory takes a completely different approach — no stamp duty concessions, but $80,000 in cash grants for first home buyers building new. That’s more cash in hand than any other state offers. The maths works strongly in favour of building rather than buying established.” — Emma Whitfield, Property Finance Analyst at BuildBudget
Northern Territory is the only state that replaced its first home buyer stamp duty concession with cash grants instead. The previous First Home Owner Discount (FHOD) ended June 30, 2021. Now first home buyers get $50,000 HomeGrown Territory Grant + $30,000 FreshStart Grant = $80,000 in cash. But you pay standard stamp duty rates on the property.
The trade-off works if you’re building. You get $80K in grants (highest in Australia) and only pay stamp duty on the land, not the construction cost. If you’re buying a house-and-land package as a single contract, you pay zero stamp duty (HLPE exemption). Plus Northern Territory has no foreign buyer surcharge and no land tax—the only jurisdiction in Australia with both.
What Are the Northern Territory Stamp Duty Rates?
Standard Rates (All Buyers)
Northern Territory uses a quadratic formula for properties up to $525,000, then switches to percentage rates above that threshold (source: Feasly).
Properties up to $525,000:
- Formula: D = (0.06571441 × V²) + (15 × V)
- Where V = property value in thousands
- Example: $500,000 property = ~$23,929 stamp duty
Properties above $525,000:
| Property Value | Stamp Duty Rate |
|---|---|
| $525,001 – $2,999,999 | 4.95% of entire value |
| $3,000,000 – $4,999,999 | 5.75% of entire value |
| $5,000,000+ | 5.95% of entire value |
Examples:
- $400,000 property: ~$15,000
- $500,000 property: ~$23,929
- $700,000 property: ~$34,650
- $1,000,000 property: ~$49,500
Every buyer pays these rates—there’s no first home buyer discount or concession. The previous First Home Owner Discount (FHOD) ended June 30, 2021.
Why Doesn’t NT Offer First Home Buyer Stamp Duty Relief?
Northern Territory does not offer stamp duty concessions for first home buyers. This is unique in Australia. Every other state offers some form of first home buyer stamp duty relief (source: Home Loan Experts).
What happened: The First Home Owner Discount (FHOD) ended June 30, 2021. It was replaced with higher cash grants instead:
- HomeGrown Territory Grant: $50,000 (new homes)
- FreshStart New Home Grant: $30,000 (new homes, all buyers)
You get $80,000 in cash grants (highest in Australia), but you pay standard stamp duty rates. The math works if you’re building new (land-only duty is cheaper + you get $80K in grants). The math hurts if you’re buying established (full duty + only $10K grant).
How Much Do You Save By Building Instead of Buying?
This is where building pulls ahead. Look at the actual numbers:
Example 1: Building in Palmerston
| Buying Established | Building New | |
|---|---|---|
| Total value | $700,000 | $700,000 |
| What stamp duty is calculated on | $700,000 (full price) | $280,000 (land only) |
| Stamp duty payable | ~$34,650 | ~$9,000 |
| You save | — | $25,650 |
Example 2: Building in Darwin Suburbs
| Buying Established $600K | Building (Land $220K + Build $380K) | |
|---|---|---|
| Stamp duty on | $600,000 | $220,000 |
| First home buyer relief? | No (NT has no FHB exemption) | No (NT has no FHB exemption) |
| Stamp duty payable | ~$29,700 | ~$6,000 |
| You save | — | $23,700 |
Both scenarios pay standard rates (no FHB discount). But building means you’re not paying stamp duty on the $380,000 construction cost—ever.
Example 3: Buying House-and-Land Package
| Buying Established $650K | House-and-Land Package $650K | |
|---|---|---|
| Stamp duty on | $650,000 | $650,000 |
| HLPE exemption applies? | No (established homes don’t qualify) | Yes (single contract, new home) |
| Stamp duty payable | ~$32,175 | $0 |
| You save | — | $32,175 |
The House and Land Package Exemption (HLPE) gives full stamp duty exemption for house-and-land packages purchased as a single contract from a registered builder (Territory Revenue Office). This is the workaround for NT’s lack of first home buyer stamp duty relief.
“The HLPE plus $80,000 in grants means a first home buyer purchasing a $650K house-and-land package saves over $110,000 compared to buying an established home. That’s an extraordinary incentive to build new in Darwin.” — James Thornton, Construction Cost Analyst at BuildBudget
You may also qualify for the First Home Owner Grant in the Northern Territory. See our Darwin building costs guide for what you’ll spend on the build itself.

How It Works
Not complicated, but you need to get the paperwork right.
- Buy the land first — you pay stamp duty on the land value only
- Sign a building contract separately — the building contract is NOT subject to stamp duty
- Important: The land and build must be separate contracts. If you buy a “house and land package” as a single contract, stamp duty may apply to the full amount (but HLPE exemption available—see below)
The Two-Contract Rule
For the land-only stamp duty saving to work:
- You need one contract for the land purchase
- You need a separate building contract with your builder
- The land settlement has to happen before construction starts (or at least, land and build are contracted separately)
- If a developer is selling you the land and building the home as a bundled deal in one contract, you may qualify for HLPE (full exemption) instead
Talk to your conveyancer if you’re unsure whether your contracts are properly separated.
What Is the House and Land Package Exemption (HLPE)?
This is the workaround for NT’s lack of first home buyer stamp duty relief.
Full stamp duty exemption for house-and-land packages purchased as a single contract from a registered building contractor (source: Feasly).
Requirements:
- Single contract for house + land (not separate purchases)
- New, detached home (never occupied)
- Must be principal place of residence for 6 months within 12 months
- Available until June 30, 2027
Not restricted to first home buyers. Anyone buying a house-and-land package gets the exemption—first home buyers, second-time buyers, investors (if they occupy it for 6 months).
This saves $20K–$30K on a typical $500K–$700K package. Combined with the $80K in grants (if you’re a first home buyer), you’re looking at $100K–$110K in total savings.
The catch: You lose design flexibility. House-and-land packages are standard layouts with fixed specifications. If you want custom design, you buy land separately and build—but then you pay stamp duty on the land.
Building saves stamp duty in NT
Separate land and build contracts = duty on land only, or HLPE for house-and-land packages
Do Foreign Buyers Pay More Stamp Duty in NT?
Northern Territory is one of only two jurisdictions (along with ACT) that does not impose a foreign buyer stamp duty surcharge (source: Feasly).
NSW, VIC, QLD, WA, SA all charge 7–8% additional stamp duty for foreign buyers. NT charges standard rates only.
If you’re a foreign buyer purchasing a $700,000 property in Darwin, you pay the same stamp duty as an Australian citizen (~$34,650). If you’re buying a house-and-land package, you pay $0 stamp duty (HLPE exemption)—the same as an Australian citizen.
This makes NT one of the most attractive jurisdictions in Australia for international property investment.
Does Northern Territory Have Land Tax?
Northern Territory is the only jurisdiction in Australia with no land tax (source: Feasly).
Every other state charges annual land tax on investment properties. NT charges nothing. Zero. No land tax, ever.
What this means:
- If you live in the property: No land tax (same as every other state for principal residences)
- If you rent it out: Still no land tax (unique to NT)
ACT has no land tax for principal residences but charges land tax on investments. NT has no land tax on anything.
This makes NT attractive for investors building new rental properties—$30K FreshStart Grant (not FHB-restricted) + full HLPE exemption on house-and-land packages + no land tax + no foreign surcharge.
When Is Stamp Duty Due in Northern Territory?
Stamp duty is due within a certain period after settlement (check with NT Revenue Office for exact timeframe). In practice, your conveyancer handles it as part of the settlement process.
Frequently Asked Questions
Do I pay stamp duty on the construction cost?
No. As long as you have separate contracts for the land purchase and the build, the building contract isn’t dutiable. That’s the whole reason building saves you so much upfront in NT.
If you’re buying a house-and-land package as a single contract, you may pay stamp duty on the full amount—but HLPE exemption gives you full exemption (until June 30, 2027).
Why doesn’t NT offer first home buyer stamp duty exemptions?
Policy decision. From October 1, 2024, NT replaced the First Home Owner Discount (FHOD) with higher cash grants instead. The HomeGrown Territory Grant ($50K) and FreshStart Grant ($30K) give you $80,000 upfront—significantly more generous than the old FHOD, which only saved ~$7K–$15K in stamp duty.
The trade-off: You get a bigger cash injection, but you pay standard stamp duty rates. The math works if you’re building new (land-only duty is cheaper + you get $80K in grants). The math hurts if you’re buying established (full duty + only $10K grant).
Can I get the HLPE exemption if I’m a first home buyer?
Yes. HLPE is not restricted to first home buyers. Anyone buying a house-and-land package as a single contract from a registered builder gets the exemption.
If you’re a first home buyer buying a house-and-land package, you get:
- Full stamp duty exemption (HLPE) — saves $20K–$30K
- HomeGrown Territory Grant ($50K)
- FreshStart New Home Grant ($30K)
- Total savings: $100K–$110K
How does NT compare to other states?
Stamp duty exemptions for first home buyers:
- Northern Territory: $0 (no concession, but HLPE for house-and-land packages)
- Tasmania: $750,000 (100% exemption, new AND established, until June 2026)
- ACT: $1,020,000 (highest threshold, income-tested)
- NSW: $800,000 (phases out)
- VIC: $600,000
- QLD: $700,000 (established), unlimited (new homes/vacant land from May 2025)
- WA: $500,000
- SA: Unlimited for new homes, $0 for established
NT is unique—no first home buyer stamp duty exemption at all. Every other state offers some form of relief. But NT gives the biggest cash grants ($80K) and has HLPE as a workaround.
Foreign buyer surcharges:
- Northern Territory: $0 (no surcharge)
- ACT: $0 (no surcharge)
- NSW, VIC, QLD, WA, SA: 7–8% additional duty
Land tax:
- Northern Territory: $0 (no land tax—only jurisdiction in Australia)
- All other states: Annual land tax on investment properties
Can I claim HLPE if I’m buying land to build on?
No. HLPE only applies to house-and-land packages purchased as a single contract from a registered building contractor. If you’re buying land separately and engaging your own builder, you don’t qualify for HLPE.
But you still save money: You pay stamp duty on the land only ($220K land = ~$6,000 duty), not on the construction cost ($380K build = $0 duty) (Territory Revenue Office). That’s $23,700 saved compared to buying an established $600K home.
“Darwin’s combination of no foreign buyer surcharge, no land tax, and the HLPE exemption makes it the most investor-friendly jurisdiction in Australia for new residential builds. No other capital can match that trifecta.” — David Park, Housing Market Researcher at BuildBudget

What if I’ve owned property overseas?
NT only looks at Australian property ownership for the HomeGrown Territory Grant (first home buyer requirement). But stamp duty rates don’t care—everyone pays standard rates in NT regardless of prior ownership.
If you owned a flat in London or a house in Auckland, that doesn’t affect your NT stamp duty. You pay the same rates as everyone else. And if you’re buying a house-and-land package, you get full HLPE exemption regardless of prior overseas ownership.
Rates current as of April 2026, based on Feasly, iSelect, and Home Loan Experts data. Your situation will have details we can’t cover here—talk to a conveyancer or solicitor before making decisions based on these numbers.
