The SMSF property loan door is closing: what the 2026 LRBA ban means for your fund

12 July 2026 · SMSF lending · 6 min read

For almost two decades, buying a residential investment property through a self-managed super fund and borrowing to do it has been a well-worn strategy for trustees wanting to build retirement wealth in a concessionally taxed environment. That strategy is now closing. As part of a deal to secure Senate passage of the government's broader tax reform package, the Treasury Laws Amendment (Tax Reform No. 1) Bill 2026 will ban new limited recourse borrowing arrangements (LRBAs) for residential property, with the change commencing around 10 August 2026 — 45 days after the Bill received Royal Assent on 26 June 2026. If you have an existing SMSF property loan, or were weighing one up, this is the moment to understand exactly where you stand.

What actually changed

The mechanism is narrow but decisive. The amendment inserts a new condition into the Superannuation Industry (Supervision) Act 1993 so that an LRBA can only be used to acquire real property if that property qualifies as business real property — commercial premises, effectively. Residential property no longer meets that test. In practice, once the ban commences, an SMSF will no longer be able to enter a new borrowing arrangement to buy a house, unit or apartment, whether newly built or established.

Importantly, this is a change to borrowing, not to property ownership itself. A fund can still hold residential property outright, and existing arrangements are largely left alone.

What's grandfathered — and what isn't

If your SMSF already has a residential LRBA in place, the reform is not retrospective. Existing borrowing arrangements are expected to continue under grandfathering provisions, and the same protection generally extends to a purchase where contracts were exchanged before the ban commenced, even if settlement or loan approval happens afterwards. What the transition period does not do is open a new window to start a fresh purchase from scratch — it exists to let deals already in motion finish, not to invite new ones.

Commercial and other business real property LRBAs are unaffected altogether, which matters for business owners who use their fund to hold the premises their own business operates from.

If you're mid-purchase right now

Anyone actively part-way through establishing an SMSF, rolling over super, setting up a bare trust or negotiating a residential contract with borrowed funds is working against a genuinely tight clock. Whether a signed contract, a finance approval, or something else is the trigger for protection matters — and given how recently this legislation landed, some of that detail is still being worked through by lenders and advisers. If this applies to you, get specific advice on your exact timeline before assuming anything is safe.

What still works for SMSF property strategies

For funds not caught up in a live purchase, the practical options going forward look like this:

• Unleveraged residential purchases — buying property inside the fund using existing cash, without borrowing, remains available and unaffected by the change.
• Commercial and business real property LRBAs — borrowing to hold a warehouse, office or shop, including one leased back to a related business at arm's length rent, continues under the existing rules.
• Reviewing an existing LRBA — if your fund already holds a geared residential property, this is a sensible time to check your loan structure, offset arrangements and refinance options with your accountant and a broker who understands SMSF lending, given how few lenders remain active in this space.

None of this replaces advice from a licensed SMSF specialist or your accountant — the rules around related-party terms, the sole purpose test and fund liquidity are unforgiving if you get them wrong, and that hasn't changed.

A worked example (illustrative only)

Say an SMSF with a $220,000 balance had been planning to use an LRBA to buy a $500,000 investment unit, borrowing the remaining balance after a 20% deposit from fund assets. If contracts are not exchanged before the commencement date, that plan cannot proceed as a geared purchase inside the fund — the trustees would instead need to consider buying a lower-value property outright with existing fund cash, holding off and building the balance further, or exploring a commercial property strategy if it suits the members' broader retirement objectives. This is a simplified, illustrative scenario only — every fund's position depends on its own balance, liquidity, member objectives and existing arrangements, and should be worked through with a qualified adviser.

Common questions

Does this affect SMSFs that already own a geared residential property?
Existing residential LRBAs are expected to be grandfathered and continue as normal — the ban applies to new arrangements from the commencement date, not to arrangements already in place.

Can my SMSF still buy commercial property with a loan?
Yes. Borrowing arrangements for business real property fall outside the ban and continue under the existing superannuation rules.

Can my fund still buy a residential property at all?
Yes, but only without borrowing — an SMSF can still acquire residential property using existing fund assets, provided it fits the fund's investment strategy and the usual superannuation rules.

What if I've already started the process but haven't exchanged contracts?
This is exactly the situation where timing is critical and advice is non-negotiable. Speak to your accountant, SMSF specialist and broker without delay to understand what, if anything, can still be protected before commencement.
