NT stamp duty calculator

The Northern Territory has one duty scale for everyone -- no separate owner-occupier/investor split, and the rate doesn't vary by property type. Up to $525,000 duty follows a quadratic formula; above that it is a flat percentage of the whole dutiable value.

No rounding rule is stated for the duty result itself -- it is an exact dollar-and-cent figure, not rounded to the dollar or the next $100 band. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

No. All of the Act's first-home-buyer duty concessions sunset no later than 30 June 2021. The only duty relief currently available in the NT is a narrow exemption for a specific house-and-land-package structure, open to any buyer, not just first home buyers.

HomeGrown Territory Grant

First home buyers of a new home get a flat $50,000 HomeGrown Territory Grant, for contracts from 1 October 2025 to 30 September 2027, with no property-value cap. Established homes are not an eligible transaction at all in this window. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

House and land package exemption

A buyer of a house-and-land package pays no duty at all, whatever the price, where a building contractor bought the land (and already paid duty on it), then built or is building a new home on it for the buyer. Not limited to first home buyers and not means-tested, but it is a narrow, structure-specific exemption -- an ordinary new home or vacant land purchase does not qualify.

No. The Northern Territory and the ACT are the only two Australian jurisdictions researched with no foreign-purchaser or surcharge-purchaser additional duty on residential conveyances. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

The Land Titles Office charges a flat $181.00 (115 revenue units, rounded down to the whole dollar, plus a $10 levy) to register a transfer, whatever the price. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

Registering a mortgage costs the same flat $181.00 (115 revenue units plus a $10 levy). (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

Lenders mortgage insurance (LMI) usually applies when you borrow more than 80% of the property’s value. It is not a government charge: premiums vary by lender and insurer, and there is no public schedule of them, so this page gives no figure. See deposit, LVR and LMI. Conveyancing, inspections and loan fees are quote-based: see complete buying costs. To add your deposit, loan repayments and the yearly cost of owning, use the true cost to buy and own calculator.

Duty is charged on whichever is greater: the consideration given, or the property's unencumbered value. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

A dutiable instrument must be lodged with the Commissioner, and duty paid, within 60 days of first execution -- one combined deadline, unlike most other states' separate lodgement/payment rules. (Parliamentary Counsel, Northern Territory, verified 1 Oct 2026)

The calculator and every figure on this page come from the same encoded rules, each transcribed from the Territory Revenue Office’s published rates or the legislation and linked to it. They apply by contract date: for a contract outside 1 July 2026 to 30 June 2027 the calculator says the date is not encoded rather than guess. It does not cover companies or trusts, transfers between relatives or spouses, deceased estates, other exemptions and concessions not listed here, or the eligibility conditions each concession carries (residence, prior ownership, income). Confirm your own position with the Territory Revenue Office calculator or a conveyancer before you rely on it.
