Borrowing inside a self managed super fund is legal — but it is one of the most tightly regulated areas of SMSF compliance in Australia. The ATO scrutinises these arrangements closely, the documentation requirements are non-negotiable, and the consequences of getting the structure wrong range from costly rectification to the fund losing its concessional tax status entirely.
This post explains exactly how SMSF borrowing works, what the rules require, and where the hard limits sit — so you can go into any conversation with a lender or adviser with a clear understanding of the framework.
Can an SMSF Borrow Money?
Yes — but only through one specific structure: a Limited Recourse Borrowing Arrangement (LRBA). This is the only form of borrowing permitted inside a superannuation fund under the Superannuation Industry (Supervision) Act 1993 (SIS Act).
Outside of an LRBA, an SMSF cannot take on debt. It cannot overdraw its bank account as a borrowing mechanism, cannot use margin loans in the traditional sense, and cannot enter into standard mortgage arrangements where the fund’s entire asset pool is exposed as security.
The LRBA structure exists precisely to contain the risk — both to the fund and to the broader superannuation system.

What Is an LRBA? (Limited Recourse Borrowing Arrangement Explained)
An LRBA is a borrowing structure specifically designed for superannuation funds. The name tells you the most important thing about it: the lender’s recourse is limited to the single asset purchased with the borrowed funds. If the fund defaults, the lender can seize that asset — but cannot pursue the fund’s other investments to recover any shortfall.
This protection exists to prevent a borrowing gone wrong from wiping out a member’s entire retirement savings. It’s a meaningful safeguard, but it comes with a structurally complex setup that must be done correctly from the outset.
Three parties are involved in every LRBA:
- The SMSF — the borrower, which makes loan repayments from its income (contributions and investment returns)
- The bare trust — a separate legal structure that holds the asset on behalf of the SMSF until the loan is repaid
- The lender — either a bank, non-bank lender, or related party (such as a member)
Until the loan is fully repaid, the SMSF holds a beneficial interest in the asset — meaning it receives the income and capital growth — but legal title sits in the bare trust. Once the final repayment is made, the asset transfers into the SMSF directly.
What Is a Bare Trust and How Does It Work in an SMSF?
A bare trust is a simple legal holding structure with one purpose: to hold the LRBA asset on behalf of the SMSF during the loan period. It is not a trading entity and has no function beyond asset custody.
The bare trustee — the person or company that acts as trustee of the bare trust — holds legal title to the asset but has no discretion over it. They act purely on the instructions of the SMSF trustees. In practice, the bare trustee is commonly a corporate trustee set up specifically for this purpose, though individual trustees can also act.
Setting up a bare trust for an SMSF requires:
- A formal bare trust deed, correctly drafted and executed
- The asset to be purchased and registered in the bare trustee’s name
- A written loan agreement between the lender and the SMSF
- The bare trust to be established before the property is purchased — it cannot be backdated
This is where many DIY LRBA attempts go wrong. The sequencing matters. If the property is purchased in the wrong name, or the bare trust is established after the fact, the entire structure may be non-compliant — and unwinding it is expensive.
Once the loan is repaid in full, the asset is transferred from the bare trust into the SMSF. This transfer attracts stamp duty in most states, though some jurisdictions offer concessions for LRBA asset transfers — your accountant should confirm the applicable treatment in your state before you reach this point.
Who Can an SMSF Borrow From?
Third-Party Lenders (Banks and Non-Bank Lenders)
The most straightforward option is borrowing from a commercial lender — a bank or non-bank financial institution that offers SMSF loans. The lender assesses the fund’s ability to service the loan, typically based on rental income from the property and member contributions.
Key differences from a standard property loan:
- LVR limits are generally lower — typically 70–80% for residential property and lower for commercial
- The loan is in the fund’s name, not the member’s personal name
- Serviceability is assessed against the fund’s income, not the member’s personal income (though some lenders consider both)
- The bare trust structure must be in place and accepted by the lender before settlement
Related Party Loans
A member, relative, or associated entity can lend money to the SMSF to fund an LRBA — this is called a related party loan. It is entirely permissible, but the ATO imposes strict conditions to prevent these arrangements from being used to circumvent arm’s length requirements.
Related party loans must comply with the ATO’s safe harbour terms, which specify:
- Interest rate: The ATO publishes safe harbour interest rates annually — separate rates apply for real property loans and loans over listed shares or units. For the current rates, refer to the ATO’s website directly, as these are updated each financial year.
- Loan-to-value ratio: Maximum 70% LVR for real property; 50% for listed shares and units
- Loan term: Maximum 15 years for real property; 7 years for listed shares and units
- Repayment structure: Principal and interest repayments required — interest-only arrangements do not meet safe harbour requirements
A written loan agreement is mandatory. A verbal arrangement — even between family members who trust each other completely — does not satisfy the ATO’s requirements and will be flagged immediately at audit. The agreement must be in place before the first repayment is made.
One tax consideration worth noting: interest paid by the fund to a related party lender is assessable income in the hands of that lender. This has personal tax implications for the member providing the loan and should be factored into the overall structure assessment.
How Much Can an SMSF Borrow to Buy Property?
There is no legislated cap on the amount an SMSF can borrow. The practical limit is determined by the fund’s ability to service the loan from its income — primarily rental income from the property and ongoing member contributions.
The ATO and SMSF auditors assess two things:
Serviceability: Can the fund meet loan repayments from its regular income without relying on the forced sale of other assets? If contributions and rental income don’t comfortably cover repayments, the fund is over-leveraged.
Liquidity: Does the fund maintain enough cash to meet its other obligations — tax liabilities, expenses, benefit payments — while servicing the loan? A fund that is entirely illiquid because all cash is consumed by LRBA repayments presents a compliance risk and will attract auditor commentary.
Over-leveraging an SMSF through property is one of the most common structural mistakes trustees make. The fund’s investment strategy must specifically address how it will manage loan repayments and maintain liquidity — and the strategy must be realistic, not aspirational.
Can I Lend Money to My SMSF?
Yes — this is a related party loan, and as outlined above, it is permissible provided it strictly follows the ATO’s safe harbour terms. The loan must be documented in a formal written agreement, structured with the correct interest rate and LVR, and repaid via principal and interest instalments over the permitted loan term.
Where trustees get into trouble is treating a related party loan informally — depositing money into the fund without a loan agreement, charging a below-market interest rate, or allowing repayments to lapse. Each of these constitutes a breach, and none of them are difficult for an auditor to identify.
If you’re considering lending money to your SMSF, have the loan agreement prepared by a specialist before any funds are transferred. Fixing a non-compliant related party loan after the fact is significantly more complex than setting it up correctly in the first place.

Can I Borrow Money From My SMSF?
No — categorically and without exception. Members cannot borrow from their own SMSF under any circumstances.
Lending fund money to a member — regardless of the amount, the interest rate offered, or the repayment terms — constitutes illegal early release of superannuation. It is one of the most serious breaches a trustee can commit, and the ATO treats it accordingly.
The consequences include:
- The fund losing its concessional tax status — all fund earnings taxed at 45%
- Significant administrative penalties applied to individual trustees
- Potential disqualification of trustees
- The illegal payment being included in the member’s assessable income and taxed at their marginal rate, plus a 20% tax offset clawback
This comes up regularly in practice — often framed as a “temporary loan” or a “short-term cash flow fix.” There is no compliant version of this transaction. If you are experiencing financial pressure and considering accessing your super early, speak to a licenced adviser about legitimate early release conditions rather than borrowing from the fund.
What Can an SMSF Borrow to Buy?
An LRBA can be used to purchase:
- Residential property — the most common use
- Commercial property — including premises used by a member’s own business
- Listed shares and units — permissible but less common due to volatility and LVR restrictions
An LRBA cannot be used to:
- Purchase vacant land (no income-producing asset to support the structure)
- Fund property development or improvements on an existing asset
- Cover fund expenses, tax liabilities, or other investments
- Purchase an asset and then substantially change it — the asset acquired must remain the same asset throughout the loan period
That last point — the “single acquirable asset” rule — is particularly relevant for property. Minor repairs and maintenance are fine. Structural renovations or developments that change the character of the asset are not permitted while the LRBA is in place.

SMSF LRBA Compliance — What the ATO Looks For
LRBAs are consistently one of the ATO’s top audit focus areas for SMSFs. The combination of large asset values, complex structures, and frequent related party involvement makes them a natural target.
Your SMSF auditor will check the following every year:
- Is there a written loan agreement in place?
- Is the interest rate consistent with ATO safe harbour rates (for related party loans)?
- Is the LVR within the permitted limits?
- Are principal and interest repayments being made on schedule?
- Is the asset held correctly in the bare trust?
- Does the fund’s investment strategy address the LRBA?
The most common compliance failure is a related party loan with no formal documentation — or documentation that was prepared after the fact and doesn’t reflect the actual terms under which the loan has been operating. Auditors are experienced at identifying retrospective paperwork.
A non-compliant LRBA doesn’t automatically trigger the worst-case outcome, but rectification is rarely straightforward. The ATO’s voluntary disclosure process offers some protection if issues are identified and reported proactively — another reason why annual accounting and audit by a specialist matters.
Frequently Asked Questions
Can an SMSF have more than one LRBA at a time?
Yes — there is no legislative limit on the number of LRBAs an SMSF can hold simultaneously. Each LRBA must be correctly structured as a separate arrangement, with its own bare trust and loan agreement. The fund’s overall liquidity and serviceability across all loans must be addressed in the investment strategy.
What happens to the bare trust if the SMSF defaults on the loan?
The lender’s recourse is limited to the asset held in the bare trust. They can take possession of and sell that asset to recover the outstanding debt — but they cannot pursue the SMSF’s other assets. This is the core protection the LRBA structure provides.
Can I refinance an existing SMSF LRBA?
Yes — refinancing is permissible, provided the replacement loan doesn’t increase the amount borrowed beyond the original loan balance. You cannot top up an LRBA through refinancing. The new loan must still comply with all LRBA requirements, and a new loan agreement must be put in place.
Does the ATO need to approve our LRBA?
No — there is no ATO approval process for LRBAs. Compliance is assessed retrospectively through the annual audit. This is precisely why getting the structure right from the start matters: there’s no pre-approval safety net.
What is the current ATO safe harbour interest rate for SMSF loans?
The ATO updates safe harbour interest rates annually. For the current applicable rates — which differ for real property loans and loans over listed shares or units — refer directly to the ATO’s website or speak with your SMSF accountant. Applying an outdated rate to a related party loan is a compliance breach regardless of intent.
Setting Up an LRBA? Get the Structure Right From Day One
An LRBA set up incorrectly is significantly more expensive to fix than to establish properly. The bare trust, the loan agreement, the interest rate, the repayment structure — every element must be in place before the first transaction occurs.
