Stamp duty in the NT at a glance
The Northern Territory works out duty on properties up to $525,000 with a formula rather than brackets: duty = 0.06571441 × V² + 15 × V, where V is the value divided by 1,000. Above $525,000, duty is a flat percentage of the whole value: 4.95% below $3 million, 5.75% from $3 million and 5.95% from $5 million. The rates haven't changed since 2017-18.
The NT's home buyer concessions only apply to contracts signed by 30 June 2021, so there is no first home duty concession now. Instead the HomeGrown Territory Grant pays $50,000 to first home buyers of a new home (contracts to 30 September 2027), and a house and land package exemption removes duty on the land in eligible packages until 30 June 2027. The NT has no foreign buyer surcharge. Registration fees are a fixed $181.
How duty is worked out
Duty is charged on the dutiable value: usually the price, or the market value if that is higher (for example a transfer between family members). Each state publishes a sliding scale of brackets. Within a bracket, you pay a fixed amount for the value up to the bracket's lower limit, plus a percentage of the amount above it. Several states charge "per $100 or part of $100", which rounds the excess up to the next $100. The calculator shows the bracket it used and the arithmetic, so you can check it against the revenue office's own figures.
Concessions then reduce the duty: full exemptions up to a price limit, phase-outs that taper the saving to nil, lower rates for owner-occupiers, or a fixed reduction. Each has conditions, usually about living in the property and not having owned one before; the calculator asks them as yes/no questions.

For values up to $525,000, duty is worked out with a formula: duty = 0.06571441 × V² + 15 × V, where V is the value divided by 1,000.

When duty is due
Within 60 days of signing the contract, usually at settlement. Your conveyancer or solicitor usually lodges and pays it at settlement from your funds.
Checking the figures
These rules were last checked on 2026-10-29 against Territory Revenue Office (Department of Treasury and Finance). Before you sign, confirm the duty with the official calculator. 6 items could not be confirmed on an official page and are marked unverified:
- The $140,000 to $3,388 example comes from a WebSearch snippet of TRO I-SD-002 (PDF blocked). It matches the Act formula.
- The LTO pages ($181) give no financial year. 2026-27 is inferred from the 115 revenue units (WebSearch summary of the Registration Regulations) x $1.49 + $10 levy.
- The 2025-26 LTO fee ($176) is derived, not read.
- A TRO I-SD-003 sheet (seen only in a WebSearch snippet) gives 5.45% for $3m and above. This conflicts with the Act and the calculator (5.75% for $3m to <$5m, 5.95% for $5m and above) and is treated as outdated.
- When duty is due is described from general knowledge of each office's rules and was not re-checked for this calculator.
- At exactly $3,000,000 and $5,000,000 the higher rate applies; the calculator applies it from the next dollar.
