How it’s calculated

The method behind your estimate

How this estimate works

This page starts with NT selected. If you change the state in the calculator, the result follows your selected state, not this page title. Choose the state or territory, purchase date and buyer circumstances. The estimate uses the selected rules release and shows the assumptions used. Standard NT conveyance duty uses a formula through $525,000, then whole-value rates of 4.95% below $3 million, 5.75% from $3 million below $5 million, and 5.95% from $5 million. Results round down to five cents, matching the official calculator checked 23 October 2026.

What to check before you act

Duty is state or territory tax. Special exemptions, foreign purchasers and unsupported eligibility cases may require an official assessment.

General information only. Check the calculator workings, selected rules date and supported scope. Not financial, credit, tax, legal or valuation advice.

FAQ

Questions people ask

Short answers about the method, the rules and what HtAG data adds.

Still have a question? Contact us

Is stamp duty based on the purchase price?

The dutiable value can be the greater of the price paid and unencumbered market value. Confirm the relevant state's valuation rules.

Are first-home concessions automatic?

No. Eligibility depends on the jurisdiction, dates, property and buyer circumstances. Use the supported options and confirm with the revenue authority.

Is the stamp duty calculator free to use?

Yes. Every HtAG calculator is free to use with your own figures, and you do not need an account. An HtAG plan adds property and suburb data to the calculators that support it.

What does an HtAG plan add to this calculator?
