Frequently asked questions

How is NT stamp duty calculated?

Under $525,000 the Territory Revenue Office applies a quadratic formula rather than bracket tables, which produces effective rates climbing toward 5.9% at the cap. Above $525,000 duty is a flat 5.95% of the whole value.

What is the Territory Home Owner Discount?

The THOD waives stamp duty completely on homes up to $500,000 for buyers who do not currently own NT residential property and intend to occupy the home. It is not limited to first home buyers, but investors who already hold NT property miss out.

Is there a foreign buyer surcharge in the NT?

No. The NT is the only jurisdiction with neither a foreign purchaser surcharge on duty nor an annual land tax, which keeps holding costs comparatively simple even though acquisition duty is steep.

When is NT conveyance duty payable?

Duty must be paid within 30 days of the liability date, generally settlement. The Territory Revenue Office charges interest on late lodgement.
