Stamp Duty on Investment Property in Australia 2026: What Investors Need to Know

Stamp duty on an investment property purchase works differently from an owner-occupied purchase in one critical way: you don’t get any of the concessions. No first home buyer exemption, no concessional rates, no off-the-plan discounts tied to owner-occupier status. On top of that, if you’re a foreign investor, every mainland state levies a substantial foreign buyer surcharge on top of the base duty. Here’s what property investors need to know about stamp duty in 2026.

Base stamp duty rates for investors

The base transfer duty rates are the same for everyone — investor or owner-occupier. What changes is your access to the reductions and exemptions that owner-occupiers can tap into. Here’s how the base duty works on a $700,000 investment property across the mainland states in 2026:

In New South Wales, stamp duty on a $700,000 residential purchase runs approximately $28,000-29,000. The NSW tiered system charges $10,530 on the first $351,000 plus $4.50 per $100 on the amount between $351,001 and $1,168,000. An investor pays the full amount — no first home buyer exemption (available up to $800,000 for owner-occupiers) and no concessional rate applies.

In Victoria, the bill is substantially higher. A $700,000 property attracts roughly $39,000-40,000 in stamp duty under the current rates. Victoria’s duty schedule is the steepest in the country, with the $6.00 per $100 rate kicking in above $130,000 of dutiable value. An owner-occupier first home buyer would be exempt up to $600,000 and receive a concession to $750,000 — the investor pays the full freight.

In Queensland, a $700,000 property attracts approximately $16,000-17,000 in transfer duty. Queensland has the lowest rates of the mainland states, and while the differential between investor and first home buyer owner-occupier is smaller (the first home concession applies only up to $700,000 for established homes), the investor still pays meaningfully more than a qualifying owner-occupier.

In Western Australia, duty on $700,000 runs approximately $27,000-28,000 — comparable to NSW. WA’s first home buyer exemption (full exemption up to $500,000, partial to $700,000 in metro areas) is unavailable to investors. In South Australia, duty on $700,000 is approximately $32,000-33,000, placing it between NSW and Victoria in cost.

Foreign buyer surcharges: the real investor cost

If you’re a foreign person — a non-resident individual, a foreign company, or a trustee of a foreign trust — every mainland state adds a surcharge on top of the base duty. These surcharges are material:

• NSW: 8% surcharge on the dutiable value (increased from 4% in recent years). On a $700,000 purchase, that’s an additional $56,000 — bringing total stamp duty to roughly $85,000.
• Victoria: 8% surcharge (increased from 7%). On $700,000, the surcharge adds $56,000 to an already high base duty of ~$40,000 — total approximately $96,000.
• Queensland: 8% additional foreign acquirer duty (AFAD). On $700,000, the surcharge adds $56,000 to the ~$17,000 base — total approximately $73,000.
• Western Australia: 7% foreign buyer surcharge. On $700,000, an additional $49,000 brings the total to roughly $77,000.
• South Australia: 7% surcharge. On $700,000, the surcharge adds $49,000 to the base ~$33,000 — total approximately $82,000.
• Tasmania and ACT: Both apply foreign investor surcharges at different rates. The Northern Territory does not currently impose a foreign buyer surcharge.

These surcharges apply regardless of whether the property is new or established, and they’re in addition to any land tax surcharges that may apply to foreign owners during the holding period.

Stamp duty and capital gains tax

Stamp duty paid on purchase is not an immediate tax deduction for rental property investors. Instead, it becomes part of the property’s cost base for CGT calculation. When you sell, the cost base is:

• Purchase price
• Plus stamp duty paid on purchase
• Plus legal fees on purchase
• Plus capital improvements (renovations, extensions — not repairs)
• Plus selling costs (agent commission, legal fees, advertising)

If you bought a $700,000 investment property, paid $28,000 in stamp duty, $2,000 in legal fees, and spent $40,000 on a renovation over the holding period, your cost base would be $770,000. If you sell for $900,000 (net of selling costs), your capital gain is $130,000. After the 50% CGT discount (held more than 12 months as an individual), the taxable gain is $65,000, taxed at your marginal rate.

The stamp duty effectively reduces your taxable capital gain dollar-for-dollar at sale time, but you pay it upfront and wait years — potentially decades — for the benefit. This timing mismatch is a real cashflow consideration for investors.

Off-the-plan investment properties

Off-the-plan purchases can offer stamp duty advantages even for investors, though the benefits are narrower than for owner-occupiers. The key mechanism is that duty is calculated on the dutiable value at the date of the contract, which for off-the-plan purchases typically means the land value plus construction costs incurred to date — not the completed value. If you contract to buy an apartment for $650,000 when only the slab has been poured, the dutiable value might be $150,000 (land value only), and stamp duty is calculated on that lower amount.

NSW offers an off-the-plan concession that allows the construction costs incurred after the contract date to be deducted from the dutiable value. This applies to all purchasers, including investors, for residential property intended for occupation (not necessarily by the purchaser — it can be rented out). Victoria’s off-the-plan concession is narrower and primarily available to owner-occupiers purchasing homes up to $1,000,000 (for the construction cost deduction). Queensland’s off-the-plan concession applies to homes valued under $550,000, which prices out most investment-grade apartments in Brisbane’s current market.

The catch with off-the-plan investment purchases is the valuation risk. If the market softens between contract date and settlement (typically 2-3 years for apartment projects), the bank may value the completed property below the contract price, requiring you to make up the difference in cash. This risk is higher for investment purchases because you don’t have the same emotional attachment to the specific property and can’t offset a valuation shortfall with first home buyer grants.

Trust and company structures

Purchasing through a discretionary trust or company adds complexity to stamp duty. Several states charge additional duty or treat the transaction differently:

In NSW, a discretionary trust purchasing residential property may be deemed a foreign person if any potential beneficiary (including unborn or unascertained beneficiaries) is a foreign person. This triggers the 8% foreign surcharge even if all current beneficiaries are Australian residents. The fix is to amend the trust deed to exclude foreign beneficiaries — something that must be done before exchange, not after stamp duty has been assessed.

In Queensland, the additional foreign acquirer duty applies to trusts with foreign trustees or beneficiaries. Corporate trustees with foreign directors or shareholders are also captured if more than 50% of the shares are held by foreign persons.

Victoria’s absentee owner provisions apply a land tax surcharge (currently 4% of the taxable value of the land) in addition to the 8% foreign purchaser additional duty on acquisition. A trust may be deemed an absentee owner if any beneficiary with a substantial interest is an absentee person.

The stamp duty implications of different ownership structures should be modelled before the entity is established — restructuring after purchase typically triggers another stamp duty event on the transfer of the property to the new entity.

When stamp duty might be deductible (the exceptions)

While purchase stamp duty is a capital cost, there are some related scenarios where stamp duty may be deductible or amortised:

Refinancing an investment loan may trigger a small stamp duty component on the new mortgage. This is treated as a borrowing expense and amortised over the shorter of the loan term or 5 years. It’s typically a few hundred dollars at most.

If you’re in the business of property development or trading — where properties are treated as trading stock — stamp duty may be deductible as a business expense in the year incurred. This is the exception, not the rule, and requires clear evidence that you’re carrying on a property business (volume, frequency, organisational structure, profit intention).

Lease stamp duty (where applicable — most states have abolished duty on commercial leases) may also be deductible. However, purchase stamp duty on the underlying property remains a capital cost regardless of how the property is used.

Planning around stamp duty as an investor

The most effective stamp duty strategy for investors is straightforward: treat it as a known, calculable cost and budget accordingly. Unlike an owner-occupier who can access concessions and exemptions, the investor’s stamp duty bill is fairly predictable: base rate plus surcharge if foreign.

The primary planning lever is purchase price. Because stamp duty is tiered and progressive, the effective rate increases with the property value. A $700,000 property in NSW attracts roughly $28,000 in duty (4.0% effective rate), while a $1,200,000 property attracts approximately $52,000 (4.3% effective rate). If you’re comparing two investment properties at different price points, factor the stamp duty differential into the total acquisition cost, not just the purchase price.

Off-the-plan purchases can reduce the upfront duty cost if the project timeline works for your investment horizon, but the development and settlement risks must be factored in. Regional properties in some states attract lower duty rates or concessional treatment — for example, regional property purchases in Victoria may qualify for a 50% duty concession for purchases under $750,000 if certain conditions are met, though this is primarily aimed at owner-occupiers.

Use the Stamp Duty calculator to run exact numbers for any property value and state combination. If you’re weighing up different investment locations, compare the total upfront cost (purchase price plus stamp duty) rather than just the headline price.
