The rate table
NT Territory Revenue Office's table, exactly as published (conveyances on or after 1 July 2017):
| Dutiable value | Duty |
|---|---|
| $0 – $525,000 | A formula, not a rate: duty = 0.06571441 × (value ÷ 1,000)² ÷ 1,000 + 1.5% of the value — about 1.5% on $100,000, rising to 4.95% at $525,000 |
| $525,001 – $2,999,999 | A flat 4.95% of the whole dutiable value |
| $3,000,001 – $4,999,999 | A flat 5.75% of the whole dutiable value |
| Over $5,000,000 | A flat 5.95% of the whole dutiable value |
How the maths works
Duty = the base for your band + the rate × the value above that band's floor
Worked example: a $650,000 home at $650,000 is charged at the flat rate for its tier: 4.95% of the whole $650,000 = $32,175.00 — an effective rate of 4.95% of the price.
What to watch
- The table we read is the Territory's own Ready Reckoner for Stamp Duty on Conveyances (document I-SD-006), listed first under "Information (I)" on the publications page in the link above — the document whose wording the formula below is quoted from.
- Duty below $525,000 is not a flat percentage — the Territory charges a formula, so the effective rate climbs with the price: about 1.5% on a $100,000 block, and 4.95% at $525,000. This calculator applies the formula to the dollar, then rounds the answer to the nearest 5 cents, which is what the Territory's own Ready Reckoner table does (its covering note says "rounded down", but the published figures are the nearest 5 cents).
- Above the threshold there are no intermediate bands — the whole dutiable value is charged at 4.95%, and the rate itself steps at $3 million and $5 million. Those are the two cliffs: at exactly $3,000,000 the rate goes from 4.95% to 5.75%, which is about $24,000 more than a dollar less would cost, and at $5,000,000 it goes to 5.95%.
- The Ready Reckoner the Territory publishes is the general conveyance rate. It does not include the home buyer concessions above, so a first home buyer (or a pensioner, or someone buying their own home) pays less than the figure here.
- Duty is charged on the dutiable value, which is the greater of the price paid and the market value of the property.
- Duty is not deductible for an investment property — it is added to the cost base instead, which reduces the capital gain when you sell.
Frequently asked questions
How much is stamp duty in Northern Territory?
On a $650,000 home it is $32,175.00. The rate is not one flat percentage — the table has 4 tiers. The Territory does not use marginal bands up the whole range: below $525,000 duty comes from the formula above, and above it the rate is charged on the whole dutiable value — so a more expensive home is charged at the higher rate all the way down. Put your own figure into the calculator above for the exact number.
What is stamp duty called here?
In Northern Territory the tax is called transfer duty. "Stamp duty" is the everyday name for the same thing.
Is it charged on the whole price or just above a threshold?
Just above. Duty is marginal: the first band is charged at its own rate, then the next, and so on. That is why the difference between a $790,000 and an $810,000 property is a few hundred dollars rather than tens of thousands.
Do first home buyers pay it?
The Ready Reckoner lists three duty concessions — the First Home Owner Discount (up to $23,928.60 off, on an established home of $650,000 or less), the Senior, Pensioner and Carer Concession (up to $8,500) and the Principal Place of Residence Rebate (up to $7,000) — and only one of them can be used on a purchase. Check the current rules — concessions change more often than the rate table does, and this calculator applies the standard rate to everyone.
What else is added to the bill?
Duty is only one line. Settlement also carries registration fees, your conveyancer's fee, and adjustment of rates and water at settlement. If the property is an investment, duty becomes part of your cost base for capital gains tax rather than a deduction.
Why does the figure here sometimes differ from the revenue office by a few dollars?
Because some jurisdictions charge the rate for every $100, or part of $100, which rounds the taxable amount up to the next full $100. This page applies that rounding where the official wording says so, and says which states do it in the notes above. The Northern Territory is the odd one out: its published table is rounded to the nearest 5 cents, and this calculator rounds the same way.
