From 10 August 2026, the rules for how a self-managed super fund can borrow to buy property change. The headlines have called it a ban. The Australian Taxation Office has now published the detail, and the detail is where the useful part sits.
This is a plain-English read of what the ATO actually said, taken from its own guidance rather than the coverage of it. If you are weighing an SMSF property decision right now, one date and one distinction will matter more than anything else you read this month.
What Changed
Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, from 10 August 2026 a self-managed super fund can only use a limited recourse borrowing arrangement to buy real property if that property is business real property. In the ATO’s words, the asset must be “wholly and exclusively used in one or more businesses.”
In practice that means an ordinary residential investment property can no longer be bought inside super using borrowed money. The change sits in the borrowing rules, so it does not stop a fund from buying property. A fund can still purchase residential property outright with its own cash, exactly as before. What it can no longer do is borrow to do it.
The ATO also made clear the change does not care who the lender is. It applies “regardless of whether the lender is a bank, non-bank lender or related party.” There is no workaround in the choice of lender.
The Line Most People Read Past
Two details in the guidance decide whether a fund is affected, and both are easy to miss.
The first is the deadline, and it is not the deadline most people assume. Transitional relief does not turn on when finance is approved, or when a loan is drawn, or when the property settles. It turns on one thing: whether a binding contract to buy the property was exchanged before 10 August 2026.
The contract exchange is the line. Everything else can happen afterwards.
The ATO spells this out with an example. A fund that exchanges a binding contract before 10 August, has its finance approved after that date, and settles twelve months later is not caught by the change. Off-the-plan purchases are protected on exactly the same basis.
The second detail is quieter and it runs the other way. For a commercial property bought with borrowing, business use is not a one-off test at purchase. The ATO says the asset “must continue to be business real property for the entire life of the LRBA.” If a borrowed commercial property stops being used in a business partway through the loan, the fund has, in the ATO’s words, “breached the law against borrowing and compliance action may apply.”
There is a sensible limit on that. A property does not fail simply because it is between tenants. The guidance says it “will not stop being business real property only because the owner is looking for a new tenant.” It is abandoning the plan to lease, not an ordinary vacancy, that causes the problem.
What This Means
Read together, the guidance leaves four things standing, and takes one common assumption away.
Still available. A fund can buy residential property outright with cash. A fund can complete a purchase where the contract was exchanged before 10 August, even if finance and settlement come later. A fund can borrow to buy genuine business real property, most often commercial premises. And an existing borrowing arrangement can be kept or refinanced after the date, provided it is the same asset, with the same or a new lender.
Taken away. The idea that a fund can keep borrowing to buy standard residential property, including a new residential build, after 10 August. That route closes.
For anyone relying on the transitional relief, the practical message is narrow and time-sensitive. The thing to protect is a binding contract exchange before 10 August. Finance and settlement timing are secondary. And once a grandfathered contract is exchanged, ordinary commercial variations are fine, but a change significant enough that the fundamental terms no longer exist can be treated as a new arrangement, which would then be tested under the new rule.
For anyone holding, or considering, commercial property inside super with a loan, the continuous business-use requirement is the part worth building a habit around. Borrowing inside super has never been set-and-forget, and this makes that plainer. The question is no longer only “did it qualify when we bought it,” but “does it still qualify, and can we show it does.”
The Move
If an SMSF property decision is live for you, one question is worth answering before the date rather than after it: is your position resting on being able to borrow for residential property inside super past 10 August? If it is, the structure needs to change, and the window to act on the transitional path is measured in days, not weeks.
The structure question, which side of the change you sit on and how to position for it, is the part worth getting right early. The tax and suitability questions belong with your accountant.
You can talk any of this through in plain English with the assistant on this site, any time, and it will point you to a conversation when a question needs a person. If structure is where you are stuck, book a discovery session and you will leave it knowing where you actually stand.
