NT first home buyer stamp duty

How first-home stamp duty works in the Northern Territory

At $500,000 the quadratic formula gives about $23,929, plus the $181 titles lodgement. That is not 4.95% of the price, and a first-home flag does not change it here.

Above $525,000 the general rate is a flat percentage of the whole dutiable value. Confirm current first-home and PPR rebates with the Territory Revenue Office before treating this figure as the amount you will pay.

NT first-home grant rules also require that applicants have not owned a home before anywhere in Australia. That is a grant test, not a duty calculation.

Common questions

How much stamp duty do first home buyers pay in the Northern Territory?

This calculator shows the general schedule. At $500,000 that is about $23,929, using the quadratic formula. Rebates are not applied. Confirm with the Territory Revenue Office.

Does ticking first home buyer change the NT stamp duty calculator?

No. First-home and PPR rebates are not modelled. The figure stays on the general Territory formula.

Is the NT first-home grant included in this duty figure?

No. The grant is a separate payment with its own never-owned-a-home test. This page is stamp duty only, and even then it is the unconcessed schedule.
