First Home Buyer Stamp Duty NSW: Does a Partner’s Past Property Count?

Yes, in most cases it does. Under the First Home Buyers Assistance Scheme, Revenue NSW treats you as ineligible if your spouse or de facto partner has ever owned residential property in Australia, or has already received the concession, even if they will not be on the contract. Sydney buyers should therefore check both partners’ ownership history before budgeting for a transfer duty exemption, not after exchange.

The Rule That Reaches Beyond the Contract

Most first home buyers assume eligibility is decided by the names on the contract for sale. For transfer duty relief in NSW, that assumption is wrong. Revenue NSW’s eligibility criteria for the First Home Buyers Assistance Scheme define an eligible purchaser as someone who has not, and whose spouse has not, at any time owned residential land in Australia, either solely or with someone else.

The guide then removes any doubt: if the buyer’s spouse has previously owned a home in Australia or received a benefit under the scheme, the buyer “will not be eligible for benefits regardless of whether the spouse is a party to the contract.”

The practical consequence is simple. Putting the property in one partner’s name does not create eligibility that the couple does not have. Where the concession is built into the deposit plan, the loan amount or the renovation budget, a partner’s history can change the whole financial model of the purchase.

Why the Stakes Are Higher in Sydney

For contracts exchanged on or after 1 July 2023, the Revenue NSW scheme page sets out a full exemption from transfer duty for new or existing homes valued at or below $800,000, and a concessional rate for homes above $800,000 and below $1 million. For vacant land, the exemption applies up to $350,000, with a concession up to $450,000.

In Sydney, those thresholds put the scheme squarely in apartment and entry-level townhouse territory, where many first home buyers are operating at the limit of their borrowing capacity. Full transfer duty on a property near the $800,000 mark runs to tens of thousands of dollars. A household that discovers late in the process that the exemption is unavailable may need to find that sum before the duty deadline, which can fall before settlement.

Who Revenue NSW Treats as a Spouse

The definition is wider than many couples expect, and narrower in one important respect.

• Married couples: A person you are legally married to is a spouse.
• De facto couples: A person you are living with as a couple in a de facto relationship is a spouse. Revenue NSW applies the Family Law Act meaning and notes there is no minimum period of cohabitation required.
• Separated married couples: A legally married person is not treated as a spouse where the couple are not living together and have no intention of resuming cohabitation.

That last point matters for buyers who are separated but not yet divorced. Their former partner’s property history may fall outside the test, but the facts of the separation need to support that position, and the application declarations must be accurate.

What Counts as Previous Ownership

The test is not limited to a home the partner lived in. Revenue NSW’s wording refers to having owned residential land in Australia “at any time”, alone or with someone else.

In practice, the questions to ask each partner include:

• Have you ever been registered on title to residential property anywhere in Australia, including as a minority co-owner?
• Have you ever owned an investment apartment, including one sold years ago?
• Did you own property with a former partner, a sibling or a parent?
• Have you previously received a first home buyer duty exemption or concession in NSW?

The guide carves out property owned solely as trustee or executor. Property held overseas is not caught by the wording, which refers to residential land in Australia.

Three Schemes, Three Different Tests

Part of the confusion comes from the fact that first home buyers in Sydney may be dealing with three separate programs at once, each with its own ownership test and administrator.

First Home Buyers Assistance Scheme (Revenue NSW)

What It Provides

• Transfer duty exemption for new or existing homes valued up to $800,000.
• Concessional transfer duty for homes valued above $800,000 and below $1 million.

How Prior Ownership Is Treated

• The buyer and spouse must never have owned residential property in Australia.
• The rule applies whether or not the spouse is named on the contract.

First Home Owner (New Homes) Grant (Revenue NSW)

What It Provides

• A $10,000 grant for new or substantially renovated homes up to $600,000.
• A $10,000 grant for eligible land and build purchases up to $750,000.

How Prior Ownership Is Treated

• Ineligible if the buyer or spouse owned residential property before 1 July 2000.
• Ineligible if the buyer or spouse lived for six continuous months in a home they owned on or after that date.

Australian Government 5% Deposit Scheme (Housing Australia)

What It Provides

• A government guarantee allowing eligible buyers to purchase with a 5% deposit.
• No lenders mortgage insurance through a participating lender.

How Prior Ownership Is Treated

• Eligibility is assessed by the participating lender.
• Housing Australia's guidance also covers buyers who have not owned property in Australia in the previous 10 years.

The distinction is significant. The grant tolerates some past investment ownership. The federal guarantee looks back ten years. The NSW duty scheme looks back indefinitely and extends to the spouse.

A couple can qualify for one, two or none of these, and a lender’s pre-approval under the federal scheme says nothing about duty eligibility.

Elyment’s guide to what a conveyancer should check before exchange on a new build covers the grant side of that picture in more detail.

Why Shared Equity Does Not Solve It

The scheme does allow eligible first home buyers to purchase with an ineligible co-buyer, provided the eligible buyers acquire at least half of the property. Revenue NSW calls this a shared equity arrangement, and the ineligible buyer pays duty on their share.

However, Revenue NSW states that shared equity does not apply where the ineligible buyer is a spouse.

The guide adds that an equity partner cannot be a spouse of an eligible purchaser.

A partner who has owned before cannot simply be recast as a minority co-owner to preserve the concession.

Where the Process Usually Breaks Down

The eligibility question is rarely difficult once it is asked. The risk lies in the sequence.

Common points of failure include:

1. Budgeting on assumption: The buyer’s broker or calculator models a full exemption because the buyer, on their own, has never owned.
2. Late disclosure: A partner’s earlier investment unit, or a share in a family property, only surfaces when the application declarations are being completed after exchange.
3. Relationship timing: A de facto relationship that has only recently become a shared household is still a de facto relationship for the test, given there is no minimum cohabitation period.
4. Duty timing: Duty is generally payable within three months of exchange, and an ineligible buyer may need to fund it at the same time as finalising the loan. Elyment explains this in its article on why the transfer duty deadline may arrive before settlement.
5. Declarations and compliance: Revenue NSW states that it checks applications against data from other government agencies and businesses, and that substantial penalties apply to false or misleading information.

A Practical Sequence Before Exchange

For couples buying a first home in Sydney, the duty question is best handled as an early project step rather than a settlement formality.

1. Map both ownership histories: List every Australian property either partner has been registered on, including sold, inherited, investment and minority interests.
2. Confirm relationship status as at the liability date: Married, de facto, or separated with no intention of resuming cohabitation.
3. Test each program separately: Duty scheme, grant and federal guarantee, against their own rules.
4. Budget for full duty where eligibility is uncertain: Treat any exemption as an upside until it is confirmed.
5. Check the residence requirement: For contracts from 1 July 2023, one eligible buyer must move in within 12 months of settlement and live there for at least 12 continuous months.
6. Brief the conveyancer before signing: Application forms and proof of identity are lodged through the solicitor or conveyancer, and the spouse’s identity documents are also required.

Elyment’s first home buyer conveyancing service and stamp duty conveyancing support are structured around confirming these points before contracts are exchanged.

Buyers relying on family funds should also read the analysis of buying a Sydney home with a gifted deposit, where the same early sequencing applies.

The Knock-On Effect on the First Year of Ownership

For many Sydney first home buyers, the money saved through the duty exemption is the money earmarked for the first round of works: replacing worn carpet, repainting a tired apartment or levelling a floor before new flooring goes down.

When the concession falls away, those plans are usually the first to be deferred.

Settling eligibility early allows the purchase budget and the post-settlement works budget to be planned together, rather than one being sacrificed for the other at short notice.

The Broader Picture

The NSW first home buyer duty concession is a household test, not a contract test.

A partner’s past ownership, even of an investment property sold long before the relationship began, can remove the exemption entirely, and neither naming one partner on title nor using a shared equity structure changes that.

Couples who examine both histories before exchange can budget with confidence and avoid funding an unexpected duty bill at the most financially stretched point of the purchase.
