First home buyers in NT
None modelled. First home help in the NT is a grant (the HomeGrown Territory Grant on new homes), not a duty concession. A house and land package bought from a building contractor may be exempt.

How it works
Up to $525,000: duty = (0.06571441 x V x V) + 15V, where V is the value in thousands of dollars. Above that, 4.95% of the whole value (5.75% from $3 million, 5.95% from $5 million).
Each state and territory publishes a sliding scale. The calculator finds the band the value falls in, then adds the fixed amount for that band to the rate for each $100 above the start of the band.
Assumptions
- Rates as at 2026-10-29.
- Not included: House and Land Package Exemption; Grants.
- All buyers are Australian citizens or permanent residents. Foreign purchaser surcharges are not included.
- First home buyer concessions assume every buyer meets the rules, such as living in the home for the required time. Only the main concession for a home is modelled, not vacant land, off-the-plan or pensioner concessions.
- The First Home Owner Grant and other grants are paid separately and are not included.
- Other costs of buying, such as transfer and mortgage registration fees, conveyancing, inspections and lender fees, are not included.
