Understanding Commercial Property Stamp Duty in Australia

What You Need to Know Before You Buy

Stamp duty represents one of the largest upfront costs when purchasing commercial property in Australia, yet it’s also one of the most misunderstood.

Whether you’re buying your first business premises or adding another investment property to your portfolio, it’s essential for you to understand these costs so you can accurately budget and avoid unwelcome surprises at settlement.

Why Stamp Duty Varies So Much Between States

Each Australian state and territory has set its own stamp duty rates and structures for commercial property transactions. So what might cost you $50,000 in stamp duty in Queensland could be $70,000 for the same property value in New South Wales. These differences can significantly impact your total acquisition costs and investment returns.

Our calculator above shows you exactly what to expect based on your state’s current rates. But here’s what else you should know: some states offer exemptions or concessions for certain commercial property types. South Australia, for example, abolished stamp duty on qualifying commercial land back in 2018—potentially saving investors tens of thousands of dollars.

Commercial vs Residential: The Key Differences

Many business owners assume commercial real estate stamp duty works the same as residential. It doesn’t. Commercial property generally attracts higher rates and fewer concessions than residential property. There are typically no first-home buyer benefits or primary place of residence exemptions when purchasing commercial premises.

However, the good news is that commercial property stamp duty can often be tax-deductible over five years when you’re purchasing as an investment. For owner-occupiers, different tax treatments apply. This is where speaking with both a specialist commercial finance broker and accountant becomes invaluable.

Foreign Buyer Surcharges: What Applies to You?

If you’re purchasing as a foreign buyer (whether an individual, company, or trust) most states apply additional surcharges ranging from 7% to 9% of the property value. That’s on top of the standard stamp duty rates. These surcharges were primarily designed for residential property markets but often extend to commercial transactions as well.

Not sure if you qualify as a foreign buyer? The rules are more nuanced than you might think. Australian citizens living overseas may or may not be caught by these provisions depending on your residency status and state regulations.

Planning Your Total Purchase Costs

Stamp duty is just one component of your total acquisition costs. When budgeting for commercial property purchase, you’ll also need to consider:

• Legal and conveyancing fees (typically $8,000–$15,000)
• Building and pest inspections
• Loan establishment fees
• Valuation costs
• Insurance

In total, your upfront costs typically range from 5% to 8% of the purchase price, with stamp duty usually representing the most significant share.
