The rate table
Department of Treasury and Finance (WA)'s table, exactly as published (current rates (page updated 30 July 2026)):
| Dutiable value | Duty |
|---|---|
| $0 – $120,000 | 1.9% for every $100 |
| $120,001 – $150,000 | $2,280.00 plus 2.85% for every $100 over $120,000 |
| $150,001 – $360,000 | $3,135.00 plus 3.8% for every $100 over $150,000 |
| $360,001 – $725,000 | $11,115.00 plus 4.75% for every $100 over $360,000 |
| Over $725,000 | $28,453.00 plus 5.15% for every $100 over $725,000 |
How the maths works
Duty = the base for your band + the rate × the value above that band's floor
Worked example: a $700,000 established home at $700,000 falls in the band starting at $360,000. Duty is $11,115.00 + 4.75% of $340,000 = $27,265.00 — an effective rate of 3.9% of the price.
What to watch
- WA publishes three tables: the general rate (used here), a concessional rate for a principal place of residence or a business asset worth $200,000 or less, and a residential rate for homes and land below $1 million. Check which one your transaction falls under.
- The rate is charged for every $100 "or part thereof", so the duty is rounded up to the next full $100 of value.
- 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 Western Australia?
On a $700,000 established home it is $27,265.00. The rate is not one flat percentage — the table has 5 tiers. It is marginal: the first band is charged at its own rate, then the next, and so on, so only the part of the value inside each band is charged at that band's rate. Put your own figure into the calculator above for the exact number.
What is stamp duty called here?
In Western Australia 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?
First home buyers pay no duty up to $450,000 and a reduced amount between $450,000 and $600,000 under the first home owner rate of duty. This calculator uses the general rate. 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.
