The WA first home owner rate now has a $600,000 no-duty threshold and an $800,000 concessional ceiling for eligible homes. If you're close to settlement, don't rely on an old calculator or a rule your friend used last year. The revised thresholds apply to eligible transactions entered into on or after 7 May 2026.
For an eligible first-home buyer, that date can matter more than the settlement date. The same is true for vacant land: no duty up to $450,000, then a concessional rate up to $550,000. Check the contract date, the property type and the approval route before money moves.
WA first home owner rate: the new thresholds
The Western Australian Government has increased the first home owner rate of duty thresholds. For newly built and established homes, no duty is payable up to a dutiable value of $600,000. A concessional rate applies above that level up to $800,000. Above the upper threshold, this first-home rate does not apply.
For vacant land, the no-duty threshold is $450,000 and the concessional band reaches $550,000. These are not minor changes for buyers building their first home. They can change the funds you need at settlement and the offer range you can sensibly consider.
| Eligible purchase | No-duty threshold | Concessional-rate ceiling |
|---|---|---|
| Newly built or established home | $600,000 | $800,000 |
| Vacant land | $450,000 | $550,000 |
The government material says the thresholds apply to the dutiable value of the whole property or land, not simply your share of it. You'll need to read the contract and speak with your settlement agent where ownership is more complicated. It isn't something a buyer can safely guess from a deposit split.
The contract date is the first date to check
The WA changes apply to transactions entered into on or after 7 May 2026. That's the transaction date, not automatically settlement day. A buyer settling in August under a contract signed before the relevant date should not assume the new rate applies. A buyer who signed on or after 7 May should check it has been used.
This is where people make a costly mental shortcut. Settlement feels like the big day, but the legislation and RevenueWA process look to when the agreement was entered into. Save the signed contract, any variation and the settlement statement in the same folder. You may need them if the assessment needs to be revisited.
For off-the-plan, option or unusual transactions, get transaction-specific advice. The ordinary headline thresholds are helpful, but the documents and the legal form still matter. You don't want a late discovery that your deal has a different treatment.
Do you qualify for the WA first home owner rate?
The first home owner rate is a concessional rate of duty, not an automatic price discount. RevenueWA aligns eligibility with the first home owner grant requirements, while its guidance also covers circumstances where a purchaser may qualify for the rate even though they are buying an established home.
That means you'll need to test eligibility as well as value. You can't rely on the sale listing to do that work for you. The property must fit the relevant category, your transaction needs to meet the conditions, and the application or pre-approval process must be handled correctly. Don't assume being a first-time buyer in everyday terms settles the question.
The July package also removed the link between the first home owner grant value caps and eligibility for the first home owner rate. So an eligible buyer may be able to access the duty concession even where the transaction value exceeds the grant cap. It doesn't mean every buyer will qualify, but it does mean you shouldn't abandon the check too soon. They are related programs, but they are not interchangeable.
A quick threshold checklist before settlement
- Identify the transaction date. Is the agreement entered into on or after 7 May 2026?
- Classify the purchase. Is it a newly built or established home, or vacant land to build on?
- Check the whole dutiable value. Compare it with $600,000 and $800,000 for homes, or $450,000 and $550,000 for vacant land.
- Check your eligibility. Use the current RevenueWA first home owner rate requirements, not a general first-buyer checklist.
- Ask who is lodging the application. Confirm whether your lender, settlement agent or you will apply or seek pre-approval.
- Keep the evidence. Retain the contract, duty certificate and approval correspondence.
What a threshold boundary looks like in practice
Say an eligible buyer signs for an established home at $595,000 on 10 May 2026. The value is within the new no-duty threshold, subject to the other eligibility conditions. If the agreed value is $640,000, the purchase is above the no-duty point but still inside the concessional band. It is not the same result as paying duty at the ordinary rate.
The same logic applies to land. A $445,000 eligible vacant-land purchase sits below the no-duty point, while a $500,000 purchase may still access the concessional rate. But don't base an offer on a rough online figure. Ask your settlement agent to confirm the dutiable value and the current assessment before you commit.
Thresholds create cliffs. A modest price movement can change the duty treatment, so give yourself enough room in the budget for the actual contract price, not just the advertised guide.
What happens if duty was assessed at the old rate?
RevenueWA says that eligible transactions entered into between the announcement date and 28 July 2026 can be self-assessed or modified in Online Duties if they have not settled. Where those transactions had already settled, they can be reassessed and a refund issued through the Online Services Portal via RevenueWA connect.
The practical lesson applies more widely: don't assume the first assessment is the final word if a new rule covers your contract date. You won't get the benefit by waiting for someone else to spot it. Ask the settlement agent what rate was applied and request the duty evidence. If it is eligible and the rate is wrong, follow RevenueWA's reassessment process instead of hoping the system will find the issue by itself.
Timing still matters. RevenueWA guidance says first home owner grant and/or rate applications must be made within the stated application period, and late applications are not accepted. Put the date in your settlement checklist now.
Use the calculator, then test the paperwork
RevenueWA provides an online calculator for transactions entered into on or after 7 May 2026. It is a useful cross-check of the estimated duty. It doesn't replace an eligibility decision or the documents that support it. You'll still need the supporting records.
Use it in two stages. First, run the likely contract price so you can budget the cash required. Second, after the contract is signed, compare the output with the duty shown by your settlement agent. If the figures are different, ask why before settlement. The right question is not just "what do I pay?" It is "which rate and value have been used, and do they match this transaction?"
My view: buyers should confirm the duty position before they go unconditional, not treat it as a settlement-day surprise. A few emails early can protect your cash buffer and your negotiation position.
