Yes, self-managed super funds can borrow, but only within a narrow set of exceptions, and limited recourse borrowing arrangements remain the main lawful pathway for buying property or other assets with debt. From 10 August 2026, any new LRBA used to purchase real property must be business real property, closing off the door on new residential LRBAs. The Australian Taxation Office (ATO) enforces these limits directly under superannuation law, and trustees carry personal responsibility for getting the structure right.
TL;DR:
- New limited recourse borrowing arrangements used to acquire real property must be for business real property from August 2026, eliminating residential property as an eligible asset.
- Borrowing for cash flow timing, such as benefit payments or surcharge liabilities, remains limited to 90 days and 10% of total assets, not for building investment positions.
- An LRBA requires a separate holding trust, funding a single asset, with legal and beneficial ownership split, and the lender cannot access the fund’s other assets if the loan defaults.
- Borrowed funds can only finance new assets or permitted replacements; using debt to fund improvements or refinance existing assets breaches the rules.
- Related-party loans must have arm’s-length terms with proper documentation, valuation, and interest rate benchmarks, or risk severe tax and compliance penalties.

What are the smsf borrowing rules that actually apply?
Superannuation law starts from a position of “no” and carves out three narrow exceptions. Outside these, and outside a properly structured LRBA, an SMSF trustee simply cannot borrow money or maintain an existing borrowing.
The ATO’s SMSF borrowing restrictions guidance sets out the exact caps trustees need to memorise:
- Member benefit payments: a fund can borrow for up to 90 days to pay a benefit that’s due to a member, capped at 10% of the fund’s total assets.
- Surcharge liabilities: the same 90 day limit and 10% cap apply where the fund needs to cover an outstanding superannuation surcharge liability.
- Settlement of security transactions: a fund can borrow for up to 7 days to cover settlement, again capped at 10% of total assets, provided the trustee held enough funds to make the acquisition without borrowing at the time the investment decision was made.
These exceptions exist for cash flow timing, not for building an investment position. A fund short on liquidity when a pension payment falls due, for example, might use the 90 day exception rather than force an untimely asset sale. None of them substitute for a genuine LRBA when the goal is acquiring property.
How does a limited recourse borrowing arrangement work?
An LRBA is the structure that makes borrowing to invest actually work inside an SMSF, and it hinges on separating legal ownership from beneficial ownership. The ATO’s LRBA guidance and SMSFR 2012/1 both describe the same core mechanics.
- Holding trust: a separate trustee holds legal title to the asset on trust for the SMSF, while the SMSF trustee retains all the beneficial rights, including rental income and capital growth.
- Single acquirable asset: the borrowed money must fund one asset, or a collection of identical assets with the same market value (such as a parcel of shares), never a mixed bundle of unrelated assets.
- Limited recourse: if the loan defaults, the lender’s rights are limited to the asset inside the holding trust. The rest of the SMSF’s assets, including members’ other super balances, stay protected.
That last point is what separates an LRBA from an ordinary mortgage. A commercial lender financing a personal investment property can chase a borrower’s other assets if things go wrong; an LRBA lender legally cannot touch the rest of the fund. SMSFR 2012/1 sets out the legal tests under sections 67A and 67B of the Superannuation Industry (Supervision) Act that determine whether an arrangement genuinely qualifies for this protection, so getting the documentation wrong at the outset isn’t a technicality; it can unwind the entire arrangement’s compliance status.
What assets can an SMSF buy with a loan?
Borrowed funds can only go toward acquiring a new asset or a permitted replacement asset, never toward propping up something the fund already owns. The ATO’s rules on assets under an LRBA are unambiguous on this point, and trustees who miss it are among the most common contravention cases the regulator sees.
- No existing assets. A fund cannot take an asset it already owns and put it into an LRBA structure retrospectively to raise finance against it.
- No improvements funded by borrowed money. Repairs and maintenance are fine; borrowing to fundamentally change or improve the asset is not, under the replacement asset rules in section 67B.
- Replacement assets must stay substantially the same. Swapping a borrowed-against asset for something fundamentally different can breach the arrangement entirely.
- From 10 August 2026, real property acquired under a new LRBA must be business real property. The asset needs to meet that definition when the LRBA starts, and the fund must keep it in business use for the entire life of the loan.
That last change is the one every trustee weighing a property purchase inside their fund needs to understand before signing anything. A warehouse leased to a trading business or a set of consulting rooms qualifies. A standard residential rental property, purchased under a new LRBA after that date, does not. Contracts exchanged before 10 August 2026 retain transitional protection under the old rules, but anything signed after loses access to residential property as an LRBA target entirely. The ATO frames this as tightening eligibility so the limited recourse protection can’t be stretched onto arrangements it was never designed for, and trustees need to monitor business use continuously, not just at settlement.
What are the rules for related-party SMSF loans?
An SMSF can borrow from a related party, including a member or their family trust, but the terms have to look exactly like what an arm’s-length commercial lender would offer. This is where the ATO sees the most documentation failures, and where the consequences can be the most expensive to unwind.
- Keep a written, signed loan agreement setting out the interest rate, repayment schedule and security, executed before or at the time the money changes hands.
- Benchmark the interest rate against a genuine commercial reference point, such as the Reserve Bank of Australia’s indicator lending rates, and keep evidence showing how the rate was set.
- Retain repayment records and independent asset valuations that support the loan-to-value ratio (LVR) used at inception and through the life of the loan.
- Record exactly where settlement funds went and who received them, so the money trail matches the acquisition, not something else.
PCG 2016/5 gives trustees a practical safe harbour: structure a related-party LRBA within its terms, covering interest rate, LVR and loan term benchmarks, and the ATO won’t treat income from the asset as non-arm’s-length income purely because of the borrowing arrangement. Skip that safe harbour, and the trustee carries the burden of proving arm’s-length terms some other way.
Pro Tip: Don’t wait for an audit to build your interest rate evidence file. Screenshot the relevant RBA indicator rate on the day you set the related-party loan terms and save it with the loan agreement, so you’re not reconstructing a benchmark from memory two years later.
Inadequate documentation on a related-party LRBA isn’t a paperwork slap on the wrist. Auditors and the ATO can recharacterise underpriced loan terms as a contribution, trigger a non-arm’s-length income finding that taxes the asset’s earnings at the top marginal rate, or flag the whole arrangement as a contravention requiring rectification.
SMSF LRBA compliance checklist for trustees
Most LRBA problems trace back to a handful of avoidable mistakes made before or shortly after settlement. Working through a checklist before signing catches most of them.
- Identify the acquirable asset precisely in the LRBA documents, matching the contract of sale, before any money moves.
- Confirm settlement funds go to the vendor, not to refinance an existing fund asset or clear another liability.
- Verify the asset isn’t already fund property and that no borrowed money is earmarked for improvements rather than acquisition costs or genuine repairs.
- For business real property, collect tenancy or trading evidence at settlement and refresh it periodically, since the business-use test applies for the entire loan term, not just at the start.
- Get an independent valuation at acquisition and revisit it annually to support the LVR and satisfy audit requirements.
- Benchmark and document interest rates for any related-party loan against a commercial reference point, and keep repayment records current.
The most common trustee error we see is treating an LRBA like a standard bank refinance or construction loan, using the same mental model that applies to buying an investment property personally. It isn’t the same. Borrowed funds inside an LRBA cannot be topped up mid-project to fund renovations, and the vendor invoice trail has to be airtight. The minimum evidence set worth retaining indefinitely: the loan agreement, holding trust deed, vendor contract and invoices, valuation reports, and every rate-benchmarking document from the loan’s start date.
Pro Tip: Set a calendar reminder for annual valuations and business-use evidence collection the same week each year. LRBA compliance isn’t a one-off event at settlement; it’s an ongoing obligation for the life of the loan.
When does an LRBA actually make sense?
An LRBA suits a fund with a clearly identified single asset, a loan size the fund can service without straining liquidity, and a trustee genuinely equipped to handle the ongoing compliance load, valuations and business-use monitoring included. It doesn’t suit a trustee hoping to borrow their way into a diversified portfolio quickly.
Alternatives are worth weighing before defaulting to debt. Funding a purchase entirely from accumulated balances avoids the LRBA machinery altogether. Staged acquisition, buying a larger stake over time as balances grow, can work where cash flow allows it. The 2026 change pushes this decision further: trustees who’d previously used LRBAs for residential property now need to redirect that strategy toward business real property or reconsider whether debt belongs in the plan at all.

How a buyer’s agent helps SMSF trustees find the right asset
Once you know what your LRBA can lawfully hold, from an entirely new business real property acquisition to identifying a genuinely arm’s-length replacement asset, the next challenge is finding one that fits. A buyer’s agent can help SMSF trustees to locate off-market and pre-market opportunities that match business real property criteria, then handle the due diligence and negotiation.
We’re not a substitute for your accountant or SMSF lawyer, who still need to draft and review the LRBA documentation, holding trust deed and loan agreement. Our role sits earlier in the process: pinpointing suburbs and assets before the wider market catches on, verifying a property’s fundamentals, and negotiating the purchase price down rather than up, since the service provider may charge a transparent fixed fee rather than a percentage commission. If you’re weighing a property purchase inside your fund under the new rules, start with a free strategy session to work out whether the numbers and the asset actually stack up. Trustees searching further south can also reach our Gold Coast buyer’s agent team for local, on-the-ground support.
FAQ
What are the rules for borrowing money from an SMSF?
An SMSF can only borrow for three narrow exceptions (90-day member benefit payments, 90-day surcharge liabilities, and 7-day settlement of security transactions, each capped at 10% of total assets), or through a properly structured LRBA.
What are the new SMSF rules from 10 August 2026?
From 10 August 2026, new LRBAs used to buy real property must acquire business real property, and that business use must continue for the entire life of the loan.
How much can an SMSF borrow?
There’s no single dollar cap under an LRBA; the loan amount depends on the lender’s terms and the fund’s serviceability. The statutory exceptions, however, are capped at 10% of the fund’s total assets.
Is SMSF borrowing banned?
No. SMSF borrowing isn’t banned; it’s restricted to the specific exceptions and to LRBAs, and new real property LRBAs are now limited to business real property rather than residential property.
