Yes. For example, a block of land worth $250,000 will attract around $6935 in stamp duty. First-home buyers purchasing land to build their home will pay the general rate upfront but may be eligible for a refund once the home is built and the First Home Owner Grant is issued.

Investors and upgraders pay the full rate. For example, on a $1,000,000 home, the estimated stamp duty is around $42,615. While no exemptions apply, the right loan structure may help reduce upfront costs. For example, certain professions are eligible for waived LMI.

Stamp duty must usually be paid within one month of the assessment notice for property purchases or within 12 months of the transaction date for land.

A certificate of duty is only issued after payment, and it’s required to register documents such as a transfer of land. Late payment penalties apply.

You could be exempt from paying stamp duty in WA if:

• You’re an eligible first-home buyer
• The property is a transfer between spouses or de facto partners
• It’s a charitable transaction
• It’s a family farm transfer

• Transfer fees
• Mortgage registration fees
• Conveyancing or legal costs
• Lender's mortgage insurance (if your deposit is less than 20%)
