When to Use Contributions and Rental Income for SMSF Loans

Lenders assess SMSF loan serviceability using the rental income the property will generate and the contributions your fund receives.

Unlike a residential home loan where your salary underwrites the debt, an SMSF commercial loan or residential business property loan is serviced entirely from within the fund. The lender assesses whether the combination of rent and ongoing contributions can cover the loan repayment, with no recourse to your personal income if the fund cannot pay. The structure is called a Limited Recourse Borrowing Arrangement, and it dictates how the lender evaluates risk and what evidence you need to supply.

How Lenders Calculate SMSF Loan Serviceability

Serviceability is calculated by adding projected rental income to the member contributions the fund receives each year, then testing whether that total can cover the loan repayment at a stressed interest rate.

Lenders apply a shading factor to rental income, typically 80%, to account for vacancy and arrears. They also discount contributions if the member is approaching preservation age or if the contribution pattern has been irregular. Consider a scenario where your fund borrows to acquire a commercial warehouse in Newstead leased at $60,000 per year. The lender shades that to $48,000. Your fund receives $30,000 in annual concessional contributions. The lender adds those and tests the combined $78,000 against a loan repayment calculated at a floor rate, often 2% above the actual rate. If the annual repayment at the stressed rate is $70,000, the application meets the serviceability test. If the repayment is $82,000, it does not, and you need to increase contributions, reduce the loan amount, or find a property with higher rent.

The assessment is mechanical, but the inputs require documentation. Lenders want three years of fund financial statements showing contribution history, a signed lease with a market rent opinion from a registered valuer, and a letter from your accountant or financial adviser projecting future contributions based on your employment income and contribution capacity. Without consistent evidence, the lender applies heavier discounting or declines the application outright.

Contribution Capacity and the Concessional Cap

The concessional contributions cap is $32,500 per member for the current financial year, and lenders will not recognise contributions above that amount when assessing serviceability.

If you are employed and your employer makes superannuation guarantee contributions of $12,000 per year, you have $20,500 of unused cap available for salary sacrifice or personal deductible contributions. The lender will accept projected contributions up to the cap, provided your taxable income supports the deduction and your accountant confirms you intend to make those contributions for the term of the loan. If you exceed the cap, you trigger excess contributions tax at your marginal rate plus an interest charge, and the excess amount is not counted toward loan serviceability. Lenders also reduce the recognised contribution if you are within five years of age 60, on the basis that contributions typically reduce as members transition to pension phase.

Where a fund has multiple members, each member's contributions can be pooled for serviceability purposes, but only to the extent those contributions are genuinely quarantined to service the loan. If one member has a balance of $1.8 million and is drawing a pension, their contributions are nil and the lender assesses serviceability based on the contributing member's capacity alone.

Rental Income Shading and Lease Requirements

Lenders shade gross rental income to between 70% and 80% of the lease amount, and they will not recognise rent from a related party unless the lease is independently valued and meets arm's length criteria.

A lease to a related party of the fund, such as a business controlled by a member, is permitted under the super rules provided the leased property is business real property and the rent is set at market value. The lender, however, applies stricter scrutiny. They require a rental determination from a qualified valuer, a formal lease agreement reviewed by a solicitor, and evidence that the tenant business has the financial capacity to pay the rent. If the related party tenant has irregular cash flow or the lease contains a rent review clause linked to business performance rather than CPI, the lender may decline to recognise the income entirely.

For an arm's length commercial lease in a precinct like Newstead, where vacancy sits at 0.5% and tenant demand is strong, lenders are more comfortable shading to 80%. In a softer market or where the tenant is a start-up with no trading history, the shading factor drops to 70% or below, which reduces the amount you can borrow against the same income.

LRBA Rules From 10 August 2026 and Refinancing Existing Loans

An LRBA entered into on or after 10 August 2026 to purchase real property can only finance business real property, meaning land and buildings used wholly and exclusively in one or more businesses.

If your fund entered into an LRBA before that date to acquire residential investment property, the new restriction does not apply, and you can maintain or refinance that loan without the property needing to meet the business real property definition. Refinancing in this context means entering into a new loan contract for the same asset, whether with the same lender or a new one. The original LRBA is grandfathered, and the property does not need to convert to commercial use.

For arrangements entered into from 10 August 2026, the property must be business real property when the loan is drawn and throughout its life. A commercial office leased to a third party tenant qualifies. A residential property leased to a tenant on a standard residential tenancy agreement does not, even if the SMSF treats it as an investment and the fund pays tax on the rental income. If the asset stops being business real property during the loan term, the fund breaches the prohibition on borrowing and compliance action may follow. This affects SMSF mortgage broker conversations from mid-August onward, because any new residential acquisition must be funded from cash or contributions without the use of an LRBA.

Loan-to-Value Ratios and Deposit Requirements

Most SMSF lenders cap loan LVR at 70% for commercial property and 80% for residential business property, meaning your fund needs a deposit of at least 20% to 30% of the purchase price plus settlement costs.

In a scenario where your fund is acquiring a commercial property at the Newstead precinct's commercial land value, with a contract price reflecting current market conditions, a 70% LVR loan requires the fund to hold 30% of the purchase price in cash or liquid assets before settlement. If the property is valued at $1 million, the fund needs $300,000 for the deposit, plus stamp duty, legal fees, and valuation costs, which in Queensland total approximately 5% to 6% of the purchase price. The total cash requirement is therefore around $350,000 to $360,000 before the lender will settle the loan.

Some lenders reduce the LVR to 60% where the borrowing fund holds illiquid assets such as unlisted shares, or where the member's total super balance is approaching the transfer balance cap and the lender perceives refinancing risk if the member moves to pension phase. Others increase LVR to 75% for established commercial buildings with long-term leases to investment-grade tenants, but those terms are rare and require the tenant's financials to be disclosed as part of the application.

Tax Treatment of Rental Income and Capital Gains

Rental income received by an SMSF in accumulation phase is taxed at 15%, and net capital gains on property held for more than 12 months are taxed at an effective rate of 10% after applying the one-third CGT discount.

If your fund acquires a commercial property and leases it for $60,000 per year, the fund pays $9,000 in tax on that income, assuming no deductible expenses. Loan interest is deductible, as are rates, insurance, repairs, and depreciation on the building and plant. A fund with $60,000 rental income and $40,000 in deductible outgoings, including interest, pays tax on $20,000 at 15%, which is $3,000. The tax liability reduces the net cash available to service the loan, and lenders factor this into the serviceability calculation by assessing whether the after-tax income and contributions can meet the repayment.

If the fund later sells the property and realises a capital gain, the gain is added to the fund's assessable income for that year, reduced by the one-third discount if the asset was held for at least 12 months, and taxed at 15%. A gain of $300,000 on an asset held for three years produces a discounted gain of $200,000 and a tax liability of $30,000. If the property was a segregated current pension asset at the time of sale, the gain is exempt and no tax is payable, but the asset can only be segregated to the extent its value does not exceed the pension account balances it supports.

When Contributions Alone Are Not Enough

Where projected contributions and shaded rental income fall short of the serviceability test, the options are to reduce the loan amount, increase the deposit, or find a property with higher rent relative to its price.

In our experience, this shortfall most often occurs where a member's concessional contributions are limited by a part-time employment arrangement or where the property is a commercial premises in a secondary location with rent below replacement cost. Lenders will not allow you to make up the gap with non-concessional contributions, because those contributions do not reduce your taxable income and the lender cannot rely on you maintaining them once the tax benefit disappears. The solution is to adjust the structure: contribute the maximum concessional amount, target a property where the rent covers a higher proportion of the loan repayment, or bring in a second contributing member to increase the fund's total recognised contribution capacity.
