Frequently Asked Questions
Who pays stamp duty in Northern Territory?▾
The buyer pays stamp duty in Northern Territory — it's a one-off transfer tax. Payment is due within 30 days of settlement (some states allow 60-90 days). Your conveyancer handles it from your settlement funds. NT has the most complex calculation under $525k (using a polynomial formula). First home buyers building / buying new homes have generous exemptions.
Are first home buyers exempt from stamp duty in Northern Territory?▾
Northern Territory offers first home buyers full or partial exemption up to $650,000. The exact eligibility requires you to be an Australian citizen or permanent resident, never have owned residential property in Australia, and intend to occupy the home for 6-12 months as your principal place of residence.
What if I'm a foreign buyer purchasing in Northern Territory?▾
Northern Territory doesn't currently have a general foreign buyer surcharge. However, FIRB (Foreign Investment Review Board) approval and fees still apply for foreign purchasers.
When is stamp duty due in Northern Territory?▾
Generally within 30 days of settlement (the date the property changes hands). Late payment incurs interest. Your conveyancer/solicitor will calculate and pay the duty to the state Revenue Office from your settlement funds. You can't roll stamp duty into your mortgage — it must be paid in cash.
Can I include stamp duty in my mortgage?▾
No — stamp duty must be paid in cash and can't be borrowed via your mortgage. Your lender will factor stamp duty into your cash requirement at settlement when assessing the loan. On an $800,000 property in Northern Territory, you'd typically need your deposit (e.g. $160k) PLUS stamp duty PLUS conveyancing/inspections (~$2-3k) all in cash.
What if I buy off the plan in Northern Territory?▾
Several states offer off-the-plan duty concessions — most notably Victoria, where you can pay duty based on the land value at contract date (not the completed property value), saving thousands. NSW and ACT have less generous off-the-plan rules. Check the specific concession with your state Revenue Office before signing — eligibility depends on contract date and completion timeline.
