WA’s New Stamp Duty Concessions (2026): What It Means for Home Buyers

The WA Government has just rolled out new stamp duty concessions, and it’s a big win for buyers, especially those considering off-the-plan or under-construction properties.

With rising property prices and cost-of-living pressures, these changes are designed to reduce upfront costs and make home ownership more accessible.

What’s New?

The biggest update is that stamp duty concessions now applies to off-the-plan multi-residence constructions (ie. Duplexes, triplexes, townhouses), with higher price thresholds and bigger savings.

1. No Stamp Duty Up to $800,000

If you purchase an eligible property off-the-plan, you could now pay $0 stamp duty on properties up to $800,000.

This means for an $800,000 property, buyers will now save more than $32,300 if they buy pre-construction.

2. Discounted Stamp Duty Up to $900,000

For properties above $800,000 concessions taper down to 50% at $900,000. So even if you're buying higher, you’re still getting meaningful savings.

3. Extra Savings During Construction

If you buy a property while it’s being built:

• 75% stamp duty concession up to $800,000

• Tapering to 37.5% beyond $900,000

Why This Matters

Stamp duty is one of the biggest barriers to entry. Reducing or eliminating it means less cash needed upfront and easier entry into the market.

There's also more buying options with these concessions now applying to apartments, townhouses, duplex/triplex-style developments. This opens the door for buyers who may have previously been priced out.

Could This Be The Right Time For You?

If you’ve been sitting on the fence about buying, this could be your window. With thresholds increasing, the government is acknowledging that property prices have risen, and adjusting support accordingly.

This is one of the most impactful updates we’ve seen for WA buyers in recent years.
