NT Stamp Duty FAQs

How much is stamp duty in the Northern Territory?
NT stamp duty uses a quadratic formula for properties up to $525,000 (effective rates around 2% to 4.5%) and a flat 4.95% rate above $525,000. For a typical $535,000 Darwin property, you would pay approximately $26,483 in duty.
Is there a first home buyer concession in the NT?
Yes. The Territory Home Owner Discount (THOD) provides up to $18,601 off stamp duty for eligible owner-occupier home buyers (not just first home buyers). The full discount is available for properties up to around $650,000; smaller property values may have the discount capped at the actual duty payable.
Does the NT have a foreign buyer surcharge?
No. The Northern Territory is the only Australian jurisdiction that does not currently impose a foreign buyer surcharge on residential property purchases. Foreign buyers pay the same standard stamp duty as Australian residents.
When is stamp duty paid in the NT?
NT stamp duty is payable within 60 days after the dutiable transaction (typically settlement). Your conveyancer or solicitor arranges payment to the Territory Revenue Office as part of the settlement process.
Why is the NT formula different to other states?
The NT uses a continuous quadratic formula for low-value properties rather than tiered brackets. This produces smoother duty figures across small price changes, but the effective rate at any given value is calculated rather than read off a bracket table. Above $525,000 the system reverts to a simple flat-rate model.
