Which Australian state has the lowest stamp duty?

It depends on the price, because the scales cross at different points. Around the middle of the market Queensland tends to be cheaper than New South Wales, which in turn is cheaper than Victoria. The only reliable answer is to compare your actual price across every jurisdiction, which the stamp duty calculator does directly.

Can stamp duty be added to my home loan?

Usually not. Lenders lend against the property's value and duty is not part of that value, so it must come from your own funds. A small number of lenders allow it to be capitalised, but doing so raises the loan-to-value ratio, which often triggers lenders mortgage insurance and costs more overall.

Do I pay stamp duty on a new build or off the plan?

Generally yes, though several states offer concessions that assess duty on the land value at the contract date rather than the finished value, which can reduce it substantially. South Australia exempts new homes entirely for eligible first home buyers. The rules differ by state and change frequently. Confirm with the revenue office before signing.

Is stamp duty tax deductible?

Not as an immediate deduction. On an investment property it forms part of the cost base and reduces your capital gain on sale, so the benefit arrives whenever you sell. On an owner-occupied home there is no tax benefit at all. The ACT is a partial exception because of its transition away from duty.

What happens if I claim a first home concession and then rent the property out?

The revenue office reassesses the duty at the full rate and charges interest, and in some states a penalty. Residence requirements are specific, typically moving in within twelve months and staying for six or twelve, and compliance is checked. If your circumstances change, contact the revenue office rather than waiting to be found.

Stamp Duty Across Australia: What Each State Charges

Why the same house costs different amounts to buy

Transfer duty, universally called stamp duty, is a state tax. There is no national rate, no national threshold and no national concession. The Commonwealth has no role in it, which is why the same $850,000 purchase attracts markedly different duty depending on which side of a border it sits.

Every jurisdiction uses a progressive scale of marginal bands: a fixed amount at the bottom of each band plus a rate on the excess above it. New South Wales charges $11,602 plus $4.50 per $100 above $387,000, up to $1,290,000. Victoria charges $2,870 plus 6% above $130,000, then switches to a flat 5.5% of the whole value between $960,000 and $2 million. Queensland is comparatively light in the middle of the market.

Two jurisdictions break the pattern entirely. The Northern Territory uses a quadratic formula below $525,000. The ACT has been progressively replacing conveyance duty with higher general rates over a twenty-year transition, so its scale falls each year while land rates rise.

First home buyer concessions and their cliffs

Most states exempt eligible first home buyers below a threshold and phase the concession out above it. New South Wales exempts purchases at or below $800,000 with a sliding concession to $1,000,000. Victoria exempts to $600,000 with a concession to $750,000. Queensland exempts to $700,000 with a concession to $800,000. Western Australia exempts to $500,000 in Perth and Peel, with a concessional rate to $700,000, or $750,000 in regional areas.

South Australia takes a different approach: eligible first home buyers of a new home pay no duty at any price, while established homes receive nothing. That makes the new-build decision far more consequential there than anywhere else.

These thresholds are cliffs rather than slopes at the bottom end, and they shape the market around them. A property listed just above a threshold loses a pool of eligible buyers, which is why negotiating under the line is sometimes worth more than the price reduction itself.

What eligibility actually requires

Concessions are narrower than the headline suggests. You generally must never have owned residential property anywhere in Australia. Not just in that state, and not just as an owner-occupier. Buying with a partner who has previously owned a home can disqualify the entire purchase in some jurisdictions rather than just their share.

Most states also require you to move in within a set period after settlement, commonly twelve months, and to live there continuously for six or twelve months. Claiming a concession and then renting the property out triggers reassessment plus interest, and revenue offices do check.

The ACT uses an income test rather than a price threshold, so household income determines eligibility regardless of what you buy. Anyone buying there should check the current income cap before assuming anything.

Budgeting for it properly

Duty is payable in cash at or shortly after settlement and cannot be added to most loans. Lenders size a loan against the property's value, and duty is not part of that value, so it has to come from your own funds alongside the deposit.

That makes duty part of your savings target, not an afterthought. On an $850,000 purchase in New South Wales a non-first-home buyer needs roughly $33,000 for duty on top of the deposit, plus conveyancing, searches, building and pest inspections, loan fees and moving costs.

Foreign purchasers pay substantial surcharge duty on top of the general rate in most states, often another seven or eight per cent, which changes the arithmetic of a purchase entirely and is assessed on residency status at the time of the contract.

Duty and how long you hold

Transaction costs are the strongest financial argument against buying for a short stay. Paying $35,000 of duty means the property must appreciate by at least that much, plus selling costs of two to three per cent, before you break even against having rented.

At typical growth rates that break-even sits somewhere between two and four years. It is the single number most worth calculating before buying somewhere you might leave, and it is why job mobility and home ownership pull against each other in a way that is often framed as a lifestyle question but is really an arithmetic one.

For investors, duty is not immediately deductible but forms part of the cost base, reducing the capital gain when the property is eventually sold. With the fifty per cent discount that recovers roughly a quarter of it in tax terms, decades later.
