SMSF Property Borrowing Checker — the 10 August 2026 LRBA Ban

What is the actual deadline for an SMSF property purchase?

The new rules commence on Monday 10 August 2026 — the 45th day after the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on Friday 26 June 2026. To rely on transitional relief the fund must have exchanged a binding contract to acquire the property before that date. The last day under the old rules is therefore Sunday 9 August 2026, and because conveyancing does not happen on a weekend the practical deadline is Friday 7 August 2026. An accepted offer, a heads of agreement or a paid holding deposit is not an exchange. Trustees in the Northern Territory should also note that Monday 3 August 2026 is Picnic Day, a Territory-wide public holiday, which removes a working day from an already short window.

Do you have to settle before the deadline?

No — and this is where most of the advice circulating in June and July 2026 is now out of date. ATO guidance released on 28 July 2026 confirmed that transitional relief turns on the exchange of a binding contract before 10 August 2026, and that settlement may occur on or after that date. It went further: the LRBA itself may be entered into on or after 10 August, so loan approval, loan documentation and drawdown can all follow the deadline. Off-the-plan purchases are assessed the same way, which matters because their completion may be years off. The bare trust is a separate question — it is not the ban’s test, but it is normally required before exchange so that the correct entity is named as purchaser and any state stamp-duty concession is preserved. The flexibility the ATO granted is about the loan, not about the structure.

Why “residential property ban” understates what changed

The Act does not work by defining residential property and prohibiting it. It works by limiting the real property an SMSF may acquire under a new LRBA to business real property — an eligible interest in land used wholly and exclusively in one or more businesses. Everything that is not business real property falls out, which is a wider net than “houses and units”. Vacant land that is not being used in a business fails. A lifestyle block fails. A single title carrying a genuine residential component — the classic office or shop with an occupied flat above — fails, because the land is then no longer used wholly and exclusively in a business. Farmland keeps a carve-out: a private dwelling such as a farm manager’s homestead does not break the test where the residential footprint is no more than 2 hectares and the dominant use remains primary production. Acquirable assets that are not real property, such as listed shares or units in a widely held trust, are untouched by any of this.

What happens to loans that already exist?

They continue. LRBAs entered into before 10 August 2026 are grandfathered under the current rules, with no sunset date and no wind-up requirement — the Government was explicit that existing arrangements would not be unwound. A fund is not required to sell the property or repay the loan early, and the arrangement can run to natural completion. Refinancing is also protected: the ATO confirmed that refinancing a pre-ban LRBA after 10 August 2026 does not give rise to a new LRBA subject to the ban, because it does not create a new contract date for the underlying acquisition, and that where the financed asset is real property it does not need to be business real property in order to be refinanced. The ordinary LRBA requirements still apply to the new borrowing, and a restructure substantial enough to be a new arrangement rather than a refinance sits outside this relief.

What can an SMSF still do after 10 August 2026?

The ban is on borrowing, not on ownership. An SMSF can still acquire residential property outright with the fund’s own cash, and it keeps every residential property it already holds. It can still enter a new LRBA over business real property — commercial premises leased to a business, including an unrelated tenant, remain available, and a temporary vacancy while the owner looks for a new tenant does not by itself break the test. Non-real-property acquirable assets are unaffected. The one durable trap is timing: the ATO stated that the asset must be business real property both when the LRBA is entered into and for the entire life of the LRBA, so a commercial property later converted to residential use, or a redevelopment that introduces a dwelling onto the title, can put an originally compliant borrowing offside years after settlement. Check the intended use across the whole loan term. Every purchase also remains subject to the ordinary superannuation rules — the sole purpose test, arm’s length dealing, and the prohibition on acquiring residential property from a related party.

Assumptions and limits of this checker

Labelled so you can judge the output. (1) It applies the commencement date of 10 August 2026, calculated as the 45th day after Royal Assent on 26 June 2026. (2) It treats the exchange of a binding contract as the transitional test, per the ATO guidance released 28 July 2026. (3) The business real property outcome is driven by the property type you select; the real test is actual use, which only an adviser looking at the specific title and tenancy can confirm — a property described as commercial may still fail, and a property described as mixed use may pass if the residential part is genuinely not used privately. (4) It does not assess whether the borrowing satisfies the other LRBA requirements, the sole purpose test, related-party acquisition rules, in-house asset rules or state stamp duty. (5) The treatment of significant post-exchange contract variations is unsettled — the ATO has said a contract changed so fundamentally that its original terms no longer exist may be a new arrangement, and the SMSF Association has asked for further clarity. This is general information, not tax, legal or financial advice; an SMSF property decision of this size should be checked with a licensed adviser before you act.
