Transfer duty on an investment property in Northern Territory, 2026-27

Transfer duty (still called stamp duty by most buyers) is the state tax paid when a property changes hands. Northern Territory charges it on the dutiable value, which for an ordinary purchase is the price paid. The figures on this page use the 2026-27 investor / general rate scale published by the Northern Territory revenue office. Owner-occupier, first-home and other concessional rates are not applied.

Official source: Territory Revenue Office (NT Government), transfer duty rates (nt.gov.au), retrieved 2026-09-17. The calculator above prices the duty for any purchase price and adds it to the cash you need at settlement.

Worked example: $750,000 investment purchase in NT

A $750,000 purchase falls in the bracket for values $525,000 and above.
In this bracket duty is 4.95% of the entire $750,000, not of the excess: $37,125.
The result is rounded down to the nearest 5 cents: $37,125.

NT transfer duty rates 2026-27: the published scale

Find the bracket the purchase price falls in, take that bracket’s published base amount, then apply its marginal rule to the amount above the threshold. The published base is used as published, never rebuilt by adding up lower brackets. The result is rounded down to the nearest 5 cents.

Foreign purchaser surcharge in NT

This page does not include a foreign purchaser surcharge for Northern Territory. Where a surcharge rate has not been verified from the revenue office’s own publication, this calculator shows the domestic figure only and says so, rather than presenting a guess under a foreign-purchaser label. Foreign purchasers should confirm their position with the Northern Territory revenue office.

What this page does not cover

Owner-occupier, principal place of residence, first-home buyer, pensioner and off-the-plan concessions. This is an investment-purchase calculator and prices the investor scale only.
Land tax. It is assessed on all the land you hold in NT, so it cannot be calculated from one property; enter your own figure in the calculator.
Any income tax consequence of the purchase. Figures here are before personal tax.
Transactions where the dutiable value is not the price paid, such as related-party transfers or where the unencumbered value is higher.

Frequently asked questions

How much is stamp duty on a $750,000 investment property in NT?

At the 2026-27 investor rate, transfer duty on a $750,000 purchase in Northern Territory is $37,125. The worked example above shows each step.

Is stamp duty higher for an investment property in NT?

The figures here use the general scale that applies when no owner-occupier or first-home concession is claimed. Whether a concession would have reduced the duty on the same property depends on the buyer’s circumstances, which this calculator does not assess; it prices the investment purchase only.

Does stamp duty affect rental yield?

Gross yield on purchase price ignores duty, because that is how listings quote it. The calculator also reports yield on total acquisition cost, which includes duty and fees and is always lower. The gap is the effect of duty on your return. See the rental yield calculator.

Where do these rates come from?

From the Northern Territory revenue office’s own published rate page, linked above, transcribed on 2026-09-17. The methodology page lists every stored bracket, its source and the state of independent verification against the official calculator.

Is duty included in the cash I need at settlement?

Yes. The calculator adds duty to the purchase price and other costs, subtracts the loan, and shows the cash required. Duty is assumed to be paid in cash, not borrowed; raise the loan amount if you intend to borrow for it. See the guide on deposit versus cash at settlement.
