SMSF lending rules explained: can you lend money to your own SMSF?
Yes, a member can lend money to their own self-managed super fund, but only under strict, arm’s length conditions. Most trustees borrowing to buy property do not use a member loan at all. They borrow externally through a Limited Recourse Borrowing Arrangement, because the rules around member loans are unforgiving and the tax penalty for getting them wrong is severe.
This guide explains how SMSF borrowing actually works in Australia: when you can lend to your own fund, why most trustees borrow externally through an LRBA, and the core rules that govern the structure. It is written for trustees who are still working out whether a purchase inside super is even possible.
Windsor Finance is a finance broker, not a lender. We hold no capital of our own and approve nothing. We arrange SMSF property finance through a panel of bank and non-bank lenders that lend under compliant LRBA structures. We do not give superannuation, tax, or financial advice. The rules below are general information. Your licensed financial adviser, accountant, and SMSF auditor handle the structuring and compliance for your fund.
Can you lend money to your own SMSF?
A member or related party can lend to an SMSF, but the loan must be on arm’s length terms. That means the interest rate, the loan-to-value ratio, the term, the repayment schedule, and the security all have to match what a genuine commercial lender would offer for the same asset. The Australian Taxation Office watches related-party loans closely. If the terms are too generous to the fund, for example a zero-interest or below-market loan, the income and capital gains from the borrowed asset can be taxed as non-arm’s length income at 45%, which wipes out the tax advantage of holding the asset in super.
There are two further traps. A loan from a member counts toward the fund’s in-house asset and related-party rules, and the sole purpose test still applies: every dollar the fund borrows and invests has to be for the retirement benefit of members, not for a member’s present-day use. Get the structure wrong and the fund can be made non-complying, which carries its own heavy tax consequence.
This is why the practical answer for most trustees is different from the technical one. You can lend to your fund. Most people do not, because an external LRBA removes the arm’s length argument entirely and the lender prices the loan commercially by default.
What is a Limited Recourse Borrowing Arrangement (LRBA)?
An LRBA is the only way an SMSF is permitted to borrow to buy an investment asset. The fund borrows to acquire a single asset, the asset is held in a separate trust, and the lender’s recourse if the loan defaults is limited to that one asset. The rest of the fund is protected.
The SMSF borrows under the LRBA to acquire one asset. For property that means one title. You cannot bundle several properties under one LRBA.
The asset sits in a separate bare trust (holding or custodian trust), usually with its own corporate trustee. The SMSF holds the beneficial interest and receives the rent and capital growth.
Once the loan is fully repaid, the SMSF has the right to take legal ownership of the asset and the bare trust is wound up.
If the loan defaults, the lender can only pursue the single asset in the bare trust. It cannot touch the fund’s other investments. This is why SMSF loans price above standard investment loans.
Because the lender carries more risk and the lender pool is smaller, SMSF loans cost more. Indicative pricing runs roughly 6.5% to 9% per annum, above a comparable standard investment loan.* Every rate here is indicative; the lender confirms on application.
The single acquirable asset rule
An LRBA can fund one asset, or a collection of identical assets treated as one for the purpose of the rule, such as a parcel of the same class of shares. For property, this means one title under one arrangement. A block of two units on two separate titles needs two LRBAs.
This rule shapes what you can and cannot do during the life of the loan. You cannot use borrowed money to change the character of the asset. Repairs and maintenance are allowed: you can fix a roof, replace a kitchen, or repaint. A capital improvement that turns the asset into something materially different is not allowed if it is funded by the borrowing, and even if funded from the fund’s own cash, it must not create a different asset while the LRBA is in place. Knocking down a house and building units on the same title, for instance, changes the asset and breaches the arrangement.
For trustees, the practical message is simple. An LRBA is for buying and holding, not for developing. If your plan involves a build or a subdivision, that is a different conversation and usually a different structure entirely.
Who you can buy from and who can use the property
The related-party rules are where many SMSF property plans come unstuck, so it is worth being precise.
Residential property
Residential property bought by an SMSF generally cannot be acquired from a related party, and cannot be lived in or rented by a related party.
- A related party means a fund member, their relatives, and entities they control.
- You cannot buy your own existing home into your fund, and you cannot buy your sister’s investment unit.
- No member or relative can rent the property, even at a market rate.
- Residential SMSF property has to be a genuine arm’s length investment.
Business real property
Business real property is treated differently. The fund can acquire it from a related party, and can lease it back to a related party, provided the dealing is at arm’s length and on market terms.
- A common, compliant purchase is a business owner buying their commercial premises into their fund.
- The trading business pays rent to the fund at a market rate.
- The rent flows into super, the business stops paying a third-party landlord, and the asset builds equity inside the fund.
Indicative LVR reflects the asset type. Lenders go to around 70% for residential SMSF security and around 65% for commercial SMSF security,* and they set conservative limits because the loan is limited recourse. The lender confirms the final position on application.
Who oversees SMSF borrowing?
SMSF lending sits under superannuation law and the Australian Taxation Office, not consumer credit. The ATO regulates SMSFs and enforces the Superannuation Industry (Supervision) Act, the sole purpose test, the in-house asset rules, and the LRBA conditions. This is a different framework from the National Consumer Credit Protection Act that governs ordinary home loans.
That distinction matters when you choose advisers. The finance side, arranging the loan, is what a broker like Windsor handles. The compliance side, whether the fund can borrow, how the bare trust is set up, and whether the deal passes the sole purpose and related-party tests, sits with your licensed financial adviser, your accountant, and your SMSF auditor. The fund’s annual audit checks the LRBA stays compliant for its whole life, not just at purchase.
Why most trustees use an external lender rather than a member loan
A member loan can work, but it puts the burden of proof on you. You have to show the ATO that every term is commercial, document it, and hold that line at every annual audit. An external LRBA removes that argument. The lender sets a commercial rate because that is its business, the loan is documented to the lender’s standard, and the arm’s length question largely answers itself.
There is a real cost difference. SMSF loans price above standard investment loans, and the lender pool is smaller than for ordinary property. The trade-off is certainty. For most trustees, paying a commercial rate to an external lender is cheaper than the risk of a member loan being challenged and the fund’s income taxed at 45%.
If you have the cash to lend your fund and want to weigh a member loan against an external LRBA, that is a question for your SMSF adviser and accountant first, then a broker once the structure is settled.
Windsor arranges the finance, not the fund and not the advice
The process works best when the structure is already settled with your adviser. We then take the deal to the lenders on our panel that lend under compliant LRBAs, compare them on rate, LVR, and appetite for the asset type, and package the application.
We are paid on a deal that settles. Indicative structuring and lender shortlisting cost nothing. Our fee model is disclosed in writing before you commit to anything; every cost is disclosed in writing, up front, before you commit. Windsor Finance is a finance broker. The purpose of each deal is confirmed in writing before it proceeds.
If you have advice in place and a property in mind, the fastest next step is a short call with one of our brokers. They will look at the asset, talk through the lenders likely to fit, and come back with indicative structures inside 24 to 48 hours.
