Short answer
A couple can sometimes use both incomes even when only one person is on title. The right setup depends on the visas, relationship, lender, duty and legal advice.
Start by separating four decisions: who owns the home, who borrows, whether the purchase is permitted and what duty applies. A lower duty estimate is not enough to choose whose name goes on the title.
Do the owners and borrowers need to be the same people?
Title
Records who is the registered owner. Ownership affects legal rights, sale proceeds, estate planning, duty and tax questions.
Loan
Records who is responsible for repaying the debt. A borrower can be liable for the full loan even without the same registered ownership interest.
A mortgage broker can explain the credit structure a lender may assess. A solicitor or conveyancer should advise on ownership, the contract and each person's legal position. Tax and duty questions need the relevant adviser or revenue authority.
Can both incomes count if only one person is on title?
This may be an option when the household needs both incomes assessed but proposes one registered owner. It is not a standard shortcut that every lender accepts.
Here's what I'd check:
- Direct benefit: why the non-owner borrower receives a real benefit from the owner-occupied home and household arrangement.
- Loan liability: whether both borrowers understand that each can be responsible for the debt.
- Ownership advice: whether the couple has obtained independent advice on sole title and future changes.
- Lender policy: whether the selected lender accepts the exact spouse or de facto non-owner borrower structure.
- Visa and transaction rules: whether foreign-investment, duty or tax treatment changes the proposed option.
If asset protection or estate planning is part of your reason for choosing sole title, get legal and tax advice on those aims. A lender accepting the structure does not settle them.

Which visa, duty and legal questions matter?
Your visas can change the loan options, what you can buy and the duty you pay.
Confirm each person's status
Record citizenship, residency, visa subclass, expiry or pathway and relationship evidence. Use the actual visa subclass and expiry date.
Get legal advice on the proposed title
Joint ownership, sole ownership and a non-owner borrower create different legal positions.
Check foreign-investment and duty treatment
Use current official rules for the exact property, people and jurisdiction. Do not rely on a national percentage or an old exemption.
Test the complete loan
Check the accepted borrower structure, income, deposit, property, costs and evidence with the selected lender.
The visa home loan guide explains the wider lender assessment. Use the FIRB guide for the foreign-investment framework. If one of you is a Kiwi, the New Zealand citizen guide covers the finance questions and the 444 guide explains visa evidence. A partner on subclass 461 needs their own assessment; they do not inherit the NZ citizen's lender or duty treatment.
The purchase rules and duty rules do different jobs
The federal rules determine whether the purchase is permitted and whether approval is needed. State or territory rules determine duty. Meeting one set of rules does not settle the other.
Treasury's current guidance says foreign investors are generally prohibited from buying established dwellings from 1 April 2025 to 30 June 2029, with limited exceptions. A qualifying purchase as joint tenants with an Australian citizen, permanent resident or eligible New Zealand citizen spouse may be treated differently.

What a foreign ownership share can cost
In this hypothetical example, 8% Queensland additional foreign acquirer duty (AFAD) on a foreign purchaser's 50% share of a $1.5 million dutiable value is $60,000: $1,500,000 × 50% × 8%. Ordinary transfer duty is extra. The example assumes AFAD applies and no exemption or relief is available. Your conveyancer should confirm which buyers and interests are liable before you compare title options. Queensland Revenue Office: assessing AFAD.
Use our foreign buyer duty calculator to compare ownership proposals, then have your solicitor confirm the treatment. NSW duty and other state rules differ; do not apply the Queensland result nationally.
When sole title may not suit you
- Ownership rights: a non-owner borrower can owe the debt without a registered share of the home. Get independent advice about that position, including what could happen after separation.
- Permanent residency may be close: compare waiting with buying now. Use the likely grant timing and full purchase costs, rather than assuming a particular saving.
- Future tax: sole ownership may affect capital gains tax and land tax, particularly if the property later becomes an investment. Ask your accountant.
- The loan may cost more: lenders that accept the structure might not suit your deposit, income or property. Compare the full loan cost with any duty difference.
Compare the full cost and ownership rights
A sole-title option may change a duty calculation in some circumstances, but it also changes registered ownership. A joint-title option may be more important to the couple even if the transaction cost is different.
I'd pause before choosing sole title from an online duty estimate alone. Compare the full costs and lender options, then ask your solicitor what sole ownership would mean for each of you.
For Queensland numbers, the Queensland stamp duty calculator can provide a general estimate. It cannot confirm foreign purchaser treatment or an exemption.
