First home buyer stamp duty and grants: what usually matters

First home is a legal status, not a vibe

Australian first-home pathways generally care about whether you (and sometimes your spouse or partner) have owned residential property before, whether you will live in the home as your principal place of residence, and whether the contract and property type sit inside published caps.

If you have owned before, many concession and grant paths are closed even if this is “your first purchase in years.” Always check the current state definition rather than assuming.

Co-purchasers are not decorative. A partner who owned previously, a parent on title “for the loan,” or a trust structure can change eligibility. Get the ownership map right before you tell yourself duty is zero.

Living in it is usually non-negotiable

Duty concessions and the Commonwealth 5% Deposit Scheme are built around owner-occupation. Selecting investment / not living in it typically removes those paths. In Queensland, first-home duty concessions also require the live-in setting — first-home buyer alone is not enough.

That is why DutyStack surfaces purpose and first-home status together. Conflicting ticks should change the estimate. If the screen does not move when you flip purpose in QLD, something is wrong with the inputs — not with the policy.

Living-in periods are enforced after settlement. Planning to “rent it for a year then move in” is how people create assessment risk. If the path requires you to occupy, plan to occupy.

Price caps kill eligibility quietly

Many FHB duty concessions and the 5% Deposit Scheme use price or dutiable-value caps that differ by state and sometimes by metro vs regional. Crossing the cap by a small amount can move you from a full exemption to full standard duty.

Run the actual offer price, not a rounded aspiration price, before you treat a concession as locked in. Auction bids that “just go a bit more” are a common way to lose a concession after emotional commitment.

Metro vs regional caps are easy to mis-apply. Confirm which cap your property sits under before you use a 5% deposit as the base case.

FHOG is separate from duty

The First Home Owner Grant is administered under state rules and often favours new homes or vacant land over established dwellings. A buyer can receive a grant and still pay duty, or receive a duty concession with little or no grant.

DutyStack shows grant credit where the inputs match the modelled path. Contract dates and temporary boost periods can change grant amounts — confirm with the administering body for your state.

Established-home buyers who budget a new-home grant invent a cash surplus that never arrives. Model established purchases with grant = $0 unless your conveyancer confirms otherwise.

State habits that matter

Queensland: purpose changes duty; FHB without Live in it is a false comfort. New South Wales and Victoria: watch price caps and scheme eligibility closely; established FHOG is often weak. South Australia and Western Australia: new vs established can rewrite both grant and duty stories. Territories: read the local duty concession mechanics rather than importing mainland grant assumptions.

Use the state FHB calculator pages and worked scenarios for the decision you are actually making. Generic national advice is how people quote the wrong table.

How couples and co-purchasers get this wrong

Many pathways look through every adult on title. One prior ownership can end the first-home story for the contract. Putting a parent on title just for serviceability can also change eligibility and surcharge exposure.

If the loan needs a guarantor, ask your broker and conveyancer how title will be structured. Guarantee without ownership is different from co-ownership. Do not improvise on the contract night.

Married and de facto status can matter for prior ownership tests. If your personal circumstances are complex, get a written view from the conveyancer before you treat a concession as certain.

Name every intended purchaser early. Adding a person later to “help the loan” can silently rewrite duty and grant eligibility.

New home, vacant land, and established stock

New homes and vacant land often sit on different grant settings to established houses. A duty concession can still exist on established stock while the grant is nil. That is normal, not a calculator bug.

House-and-land packages can split timing between land settlement and build. Cash planning must cover the land duty event you actually face, not a blended fantasy of the finished home price alone. Confirm the dutiable transaction with your conveyancer.

Off-the-plan contracts can change dutiable value treatment. If you are buying off the plan, do not rely on an established-home mental model.

After settlement: living-in evidence

Concessions that require occupation are not decorative. Revenue offices can ask for evidence later. If you claim a live-in path, plan utilities, enrolment, and actual residence accordingly.

If your life plan is to rent the property immediately, do not claim an owner-occupier concession to win the purchase. The short-term cash win is not worth an assessment dispute.

Tell your broker and conveyancer the same occupancy story. Mismatched stories create delayed settlements and messy credit files.

A state-by-state mental model

Queensland: purpose can rewrite duty; FHB without Live in it is a false comfort. New South Wales: watch scheme and duty caps; established grants are often weak. Victoria: price and eligibility move outcomes quickly — stretch carefully.

Western Australia and South Australia: new versus established can change both grant and duty stories. Territories: read local duty concession mechanics rather than importing mainland grant headlines.

This mental model is a starting map, not a substitute for the current revenue-office page for your contract date. Settings move with budgets.

Open the matching state FHB calculator page after you read this guide. The briefing on that page is there to stop generic national advice from running your bid.

Documents to gather before you claim anything

Have identity, residency or citizenship evidence, and a clear prior-ownership history ready. If a partner is involved, gather theirs too. Concessions die in incomplete files.

If you have owned before through a trust, company, or overseas, say so early. Hidden prior ownership is how assessments turn ugly after settlement.

Keep contract drafts aligned with the occupancy story you will claim. Last-minute purpose flips on the form are a red flag to everyone in the chain.

Putting concessions next to repayments

A duty concession that saves five figures can still leave a loan you cannot sleep with. After you confirm a concession path, run repayments on the real loan size including any capitalised LMI on non-scheme alternatives.

Couples sometimes win on duty and lose on serviceability because they stretched price to “use the concession.” The concession is not a reason to buy an unaffordable property.

If the concession requires living in the home, your medium-term life plan must support that. Career moves interstate six weeks after settlement are how people create compliance stress.

Concession math before you fall in love with a listing

Write three numbers before you book a second inspection: estimated duty with the concession path, estimated duty if the concession fails, and deposit cash at your intended LVR. If you can only fund the first number, you are not ready to bid near a cap.

Bring those three numbers to your broker meeting. Good brokers would rather kill a fantasy early than unwind an unconditional contract.

If a selling agent promises zero duty, ask which concession path and which cap they mean. Vague reassurance is marketing, not an assessment.

Revisit the numbers whenever the offer price moves by more than a small step. Caps and brackets are unforgiving at the edges.

Practical checklist before you exchange

Print this list and tick it with your conveyancer, not only in your head:

• Confirm prior ownership history for every purchaser on title
• Confirm you can meet the living-in period for any concession you claim
• Confirm the contract price is inside the relevant cap
• Confirm new vs established treatment for grant and duty
• Confirm foreign purchaser status for every person on title
• Have your conveyancer lodge the correct concession claim — calculators do not lodge
