Commercial Property Stamp Duty Calculator

It produces an indicative estimate of the stamp duty payable on a commercial property purchase based on the state's rate schedule, the purchase price, and whether you're buying as a foreign acquirer. Toggle the all-states comparison to see the same purchase price across every Australian jurisdiction side by side, which is especially useful for investors who are flexible on location.

The figures are for budgeting and comparison purposes only. Your conveyancer will calculate the definitive amount at lodgement based on the specifics of your transaction. Use this calculator before you make an offer to factor stamp duty into the price you're willing to pay, then rely on your conveyancer's quote to settle. Running the numbers early helps you avoid unwelcome surprises at settlement.

No, and this trips up a lot of first-time commercial buyers. Commercial and residential stamp duty use different rules. Residential buyers get access to first-home buyer concessions, primary residence exemptions and various discounts that simply don't exist on the commercial side. What you get instead is actually simpler: there's no complicated means-testing or eligibility criteria to navigate. You pay the rate for your state, full stop. The trade-off is that commercial rates are often higher than residential at the same price point, which is exactly why running the numbers through this calculator before you make an offer matters.

Not directly, no. Stamp duty has to be paid in cash at settlement. It goes straight to the state revenue office and isn't part of the purchase price your lender funds. This catches first-time commercial buyers off guard. On a $1.5M purchase you could be looking at $60,000 to $80,000 in stamp duty that needs to be liquid and available on settlement day, on top of your deposit.

What I do sometimes see is buyers using equity in an existing property to cover the stamp duty, essentially borrowing against something they already own. Others bridge the cash flow gap with a short-term business loan if their position is strong enough to service it. It's worth a conversation about your full picture before you commit to a purchase price. Book a call with our team and we'll run through the numbers with you.

Stamp duty is a state tax, not a federal one. Every state and territory sets its own rates, thresholds, and exemptions. The result is genuinely material. The same $1.5M industrial property could attract roughly $80,000 in NSW, $63,000 in Victoria, and zero in South Australia. That's a 5% swing on the total acquisition cost, just based on which side of a state border you're buying. For commercial property investors running on tight yield margins, the gap matters more than most realise.

Recent reform has widened the gap further. South Australia abolished stamp duty on most qualifying commercial land in July 2018. The ACT is gradually phasing out stamp duty entirely in favour of an annual land tax. NSW now offers an optional annual property tax for some buyers as an alternative to upfront duty. None of these reforms apply uniformly across all commercial property types or buyer profiles, so always verify your specific scenario with the relevant state revenue office or your conveyancer.

It varies by state, but most jurisdictions require payment within 30 days to 3 months of the dutiable transaction. NSW gives you 3 months from contract date. Victoria typically 30 days from settlement. Queensland 30 days from the dutiable transaction date. In practice, stamp duty is almost always settled at the same time as the property purchase itself. Your conveyancer will calculate the duty, lodge the documents, and arrange payment as part of the settlement process. You just need the cash sitting ready in your trust account at settlement. Late payment attracts penalty interest and in some states a tax default, so it's not something worth getting wrong.

Yes, in most states. Foreign acquirer surcharges typically range from 7% to 9% of the property value, on top of standard stamp duty. So a foreign buyer purchasing a $2M commercial property could pay an extra $140,000 to $180,000 in surcharge alone.

The rules around who counts as a foreign buyer are more nuanced than you might expect. Australian citizens living overseas may or may not be caught depending on residency status and state-specific definitions. Companies and trusts have their own foreign-ownership thresholds. If your purchase has any cross-border element to it, always confirm with your conveyancer before committing. The surcharge can shift the deal economics significantly.

The short answer is yes, but not in the way most people expect. You don't get to claim it all in the year you pay it. For investment properties, the ATO generally treats stamp duty as a capital cost. It's either deducted over five years under the blackhole expenditure provisions, or added to your cost base and factored into any capital gain when you eventually sell. For owner-occupiers using the property in their business, there's a slightly different treatment again. It's one of those areas where working with both a specialist commercial finance broker and your accountant before you buy is genuinely worth doing, not after. The right loan structure and ownership entity from day one make a real difference to your tax outcome over the life of the property.

Yes. Your SMSF pays stamp duty just like any other buyer. There's no super-specific exemption here. The fund is the purchasing entity so the duty applies at the standard commercial rate for your state.

That said, the reason so many people buy commercial property through their SMSF isn't to avoid stamp duty. It's everything that happens inside the fund after settlement: concessional tax on rental income, potential capital gains exemption once the fund moves into pension phase, and the ability to lease the property back to your own business. The stamp duty is a one-off cost; the tax advantages run for decades. If you want the full picture on how SMSF commercial property finance actually works, our SMSF guide walks through it in detail.

It depends, and it can be significantly cheaper than buying the property directly. The rules aren't what most people assume. Most states apply landholder duty rules to substantial share acquisitions in companies whose primary asset is land. The threshold varies by state, typically around 50% interest acquired in a company holding more than $2 million of land. Below the threshold, the transaction may attract only standard share transfer duty, which is much lower. Above the threshold, landholder duty applies at rates that are sometimes still lower than direct property duty.

The catch is that share purchases come with everything else the company owns or owes, including liabilities, tax history, and contractual obligations. It's not a structure to use casually. If you're seriously considering it, engage a commercial property lawyer and tax advisor early. The savings can be material, but the due diligence required is meaningfully different from a straight property purchase.

South Australia wins this one convincingly. Most commercial properties classified as qualifying land (offices, retail and industrial) have paid zero stamp duty in SA since July 2018. It's a genuine advantage and we've seen it shift decisions for investors who were tossing up between states. For everywhere else, Queensland tends to come out ahead of NSW and Victoria at most commercial price points, but the gap narrows as the purchase price goes up. Run your figures through the state-by-state comparison in the calculator above. It'll show you the exact dollar difference for your purchase price, which is often more persuasive than any general rule of thumb.

There's no magic trick, but there are a few legitimate levers worth knowing. State choice matters more than most buyers realise. The same $1.5M industrial property could attract roughly $80,000 in NSW versus zero in SA. If you're flexible on location, the all-states comparison in the calculator above shows you the difference instantly.

State-specific exemptions and concessions apply to particular situations: primary production land, charity ownership, corporate restructures, and off-the-plan purchases in some states. Owner-occupier buyers sometimes qualify for small business concessions that pure investors don't. These won't apply universally, but they're worth checking with your conveyancer if your circumstances suggest one might fit.

Transaction structure can sometimes change the equation too, particularly buying shares in a company that owns the property rather than the property directly (covered separately above). For a deal complex enough to warrant any of these strategies, the savings from professional advice from a property lawyer or tax advisor pay for themselves many times over.

Stamp duty is usually the largest single upfront cost, but it's not the only one. A typical commercial property purchase includes legal and conveyancing fees of $3,000 to $8,000 depending on transaction complexity, building and pest inspections of $800 to $1,500 for most properties (more for industrial or specialised assets), and loan establishment and valuation fees of $1,000 to $2,500. Insurance also needs to be in place from settlement day.

In total, upfront costs typically run 5% to 8% of the purchase price, with stamp duty as the biggest line item. For first-time commercial buyers, our first-time buyers guide walks through the full process and what to plan for.

Once you've got a feel for the upfront cost, the next step is confirming you can borrow what you need. Use our borrowing capacity calculator to test your serviceability, the repayment calculator to model monthly outgoings, and the buy vs rent calculator to confirm whether buying stacks up over your holding period.
