Off-the-Plan Duty Concession WA What Buyers Need to Know Before Signing

What Is the Off-the-Plan Duty Concession?

The off-the-plan duty concession in Western Australia is designed to encourage property investment and support the construction industry.

In simple terms, it allows eligible buyers to pay reduced transfer duty (stamp duty) when purchasing certain properties before or during construction.

This can lead to substantial savings, particularly for buyers entering the market with limited cash flow.

 

Why This Matters for Property Buyers

For many buyers — especially first-home buyers — upfront costs are the biggest barrier to entry.

Between deposit requirements, legal fees, and stamp duty, the total cost can quickly become overwhelming.

That’s why concessions like this, combined with schemes such as those discussed in our guide on the 5% Deposit Home Loan Scheme NSW: What You Really Need to Know, are becoming increasingly important.

But while the savings are real, so are the risks — particularly if the contract isn’t structured correctly.

 

Key Changes to the Off-the-Plan Duty Concession (2026 Update)

Recent updates introduced in March 2026 have expanded the concession and made it more accessible.

Key changes include:

• Increased property value thresholds (up to $800,000)
• Phased concession rates above that threshold
• Extension of the scheme for an additional two years
• Expansion to include certain strata and community title developments

These changes apply to transactions entered into from 12 March 2026, with implementation expected once legislation and system updates are completed.

 

Who Is Eligible?

Eligibility depends on several factors, including:

• The type of property (typically apartments, townhouses, or strata developments)
• The stage of construction (pre-construction or under construction)
• The contract date
• The purchase price relative to thresholds

Because these criteria can change and vary depending on timing, buyers should not rely on assumptions.

“We regularly see buyers assume they qualify for concessions — only to find out later that one contract detail made them ineligible.”

 

Where Buyers Go Wrong

While the concession sounds straightforward, the reality is more complex.

Common mistakes include:

• Signing contracts outside eligible timeframes
• Purchasing properties that don’t meet scheme criteria
• Failing to structure contracts correctly
• Not understanding how concessions phase out above certain values

These issues are rarely picked up by banks or conveyancers, because they sit at the intersection of legal interpretation and transaction structure.

 

Why Legal Review Before Signing Is Critical

A property lawyer doesn’t just review your contract — they ensure your purchase aligns with government concessions, lender requirements, and long-term risk.

This includes:

• Confirming eligibility for the duty concession
• Reviewing contract timing and clauses
• Ensuring no terms invalidate your entitlement
• Advising on structure (especially for off-the-plan purchases)

This becomes even more important for buyers also relying on structured entry strategies, such as those outlined in How Specialist Property Lawyers Help You Secure the 5% Deposit Scheme (When Banks and Conveyancers Can’t).

 

The Risk with Off-the-Plan Purchases

Off-the-plan purchases come with additional layers of complexity beyond standard property transactions.

These include:

• Long settlement timeframes
• Developer-driven contract terms
• Potential delays in construction
• Variations in final property specifications

If these factors are not properly accounted for, they can impact both:

• Your eligibility for concessions
• Your ability to settle

“Off-the-plan contracts are drafted to protect developers — not buyers. That’s why legal oversight is essential.”

 

Real Scenario: Saving vs Losing the Concession

Scenario 1: Proper Legal Review

A buyer entered into an off-the-plan contract with legal advice early.

The contract was reviewed and adjusted to align with concession eligibility requirements.

The outcome:

• Buyer qualified for the concession
• Saved thousands in stamp duty
• Completed settlement without issue

Scenario 2: No Legal Review

Another buyer signed an off-the-plan contract relying only on the agent’s advice.

The contract fell outside eligibility timing requirements.

The outcome:

• Buyer did not qualify for the concession
• Paid significantly higher duty
• No recourse after signing

“The difference wasn’t the property — it was the legal advice before signing.”

 

How This Fits Into Your Overall Property Strategy

The off-the-plan duty concession should not be viewed in isolation.

It works best when combined with a broader strategy that includes:

• Deposit structuring (e.g. 5% schemes)
• Loan approval alignment
• Contract timing
• Legal protection

When these elements are aligned, buyers can significantly reduce both upfront costs and long-term risk.

 

When Should You Speak to a Lawyer?

You should speak to a property lawyer:

• Before signing any off-the-plan contract
• When relying on concessions or grants
• When timelines are unclear or complex
• When the purchase involves multiple conditions

Waiting until after signing limits your options significantly.

 

My Final Thoughts

The off-the-plan duty concession is a valuable opportunity for buyers — but only if it’s applied correctly.

Without proper legal oversight, what looks like a saving can quickly become a costly mistake.

“In property transactions, small details in the contract often determine whether you save money — or lose it.”

If you’re considering an off-the-plan purchase or relying on a duty concession, make sure your contract, timing, and eligibility are aligned before you commit.

Who qualifies for the off-the-plan duty concession in WA?
Eligibility depends on factors such as the contract date, property type (usually apartments or strata developments), construction stage, and purchase price thresholds. Buyers must ensure their contract meets all current requirements at the time of signing.

How much can you save with the off-the-plan duty concession?
Savings vary depending on the purchase price and timing, but many buyers can save thousands to tens of thousands of dollars in stamp duty compared to standard property purchases.

Do I need a lawyer for an off-the-plan purchase?
Yes. Off-the-plan contracts are complex and often drafted in favour of the developer. A property lawyer ensures the contract aligns with concession eligibility, protects your rights, and prevents costly mistakes.

Can I lose the off-the-plan duty concession after signing?
Yes. If your contract does not meet eligibility criteria — including timing, structure, or property type — you may lose the concession and be required to pay full stamp duty. This is why legal review before signing is critical.

What are the risks of buying off-the-plan?
Common risks include construction delays, contract terms favouring the developer, changes to the final property, and potential loss of eligibility for concessions. These risks should be carefully reviewed before committing.

How does the off-the-plan concession work with other property schemes?
The concession can be used alongside broader property strategies, including low-deposit entry pathways. However, all elements — finance, contract, and eligibility — must align correctly to avoid issues at settlement.

When should I get a building inspection for an off-the-plan property?
Inspections should be carried out at key stages, including construction milestones, practical completion, and during the defects liability period.

For buyers in Western Australia, engaging a qualified expert early — such as those providing building dispute expert witness services in Perth — can help identify defects and prevent disputes before they escalate.

Can defects still occur in new builds?
Yes. Even newly constructed properties can have structural issues, waterproofing failures, or workmanship defects. Independent inspections are essential to identify these issues early.

What happens if there is a dispute with the builder?
If defects are not resolved, disputes may escalate to the State Administrative Tribunal (SAT). In these cases, having a properly prepared expert report can significantly strengthen your position and improve your outcome.
