Member balance levels control how much your Self-Managed Super Fund can borrow when refinancing a loan.
A fund with a total balance of $400,000 refinancing a loan secured against a property valued at $500,000 has less capacity than the same fund with $600,000 in total balances. Lenders assess the fund's ability to service debt based on rental income and available member balances, not just the property value. When you refinance an SMSF loan, the lending criteria apply as if you were applying for the first time, and balance levels sit at the centre of that assessment.
The difference between a successful refinance and a declined application often comes down to whether the fund has sufficient liquid balances to support the borrowing, cover holding costs during vacancies, and meet lender reserve requirements.
Why Lenders Assess Total Member Balances During Refinance
Lenders use total member balances as a primary measure of the fund's financial capacity to support the loan. The fund must demonstrate it can meet loan repayments during rental vacancies, cover property expenses, and absorb rate increases without breaching the sole purpose test.
Consider a fund refinancing a $350,000 loan against a commercial property in Brisbane's Fortitude Valley precinct. The property generates $42,000 in annual rent, but the fund also holds $180,000 in cash and listed securities across member accounts. A lender will assess whether the fund can service repayments at a stressed interest rate using rental income alone, then consider the reserve position based on total balances. A fund with only $80,000 in reserves may not meet the lender's minimum buffer requirement, even though the loan-to-value ratio remains acceptable. The refinance stalls not because of equity, but because the balance structure does not support the loan size.
This calculation occurs independently of how much equity exists in the property. A property with 50 percent equity can still fail serviceability if member balances are too low to provide adequate reserves.
How Low Balances Limit Refinancing Options
Funds with low member balances relative to loan size face restricted access to lenders and higher interest rates. Most SMSF lenders require the fund to hold a minimum percentage of the loan amount in accessible reserves, typically between 10 and 20 percent depending on property type and tenancy status.
A fund with $220,000 in total balances seeking to refinance a $280,000 loan may find only one or two lenders willing to proceed, and those lenders may price the loan above the standard SMSF variable rate due to the elevated risk profile. The same fund with $400,000 in balances has access to a broader panel of lenders and lower rates because the balance coverage provides a stronger buffer.

Low balances also restrict the ability to access offset accounts or rate discounts that require higher balance thresholds. Some lenders link their most competitive SMSF rates to minimum fund balance levels, meaning a fund with marginal reserves not only has fewer options but pays more over the life of the loan.
The Effect of Balance Levels on Residential Refinancing After the 2026 Restriction
Refinancing an existing residential SMSF loan remains permissible under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, provided the arrangement does not constitute a new borrowing. The ATO has not yet published updated guidance on what changes might trigger a new arrangement, but the existing position under Practical Compliance Guideline PCG 2016/5 remains current.
A fund that entered into a residential limited recourse borrowing arrangement before the commencement date can refinance that loan without being caught by the restriction on new residential LRBAs. The refinance must relate to the same single acquirable asset, maintain the limited recourse character of the original arrangement, and meet arm's length terms. Member balance levels still determine whether the refinance proceeds, because lenders apply the same serviceability and reserve assessments regardless of whether the loan is classified as existing or new.
A fund refinancing a $420,000 loan against a Brisbane property in Paddington with total member balances of $480,000 will be assessed on whether those balances provide sufficient capacity to service the loan at stressed rates and hold required reserves. If the fund's balance has declined since the original loan was written, the refinance may be declined even though the loan-to-value ratio has improved due to capital growth.
Commercial Loan Refinancing and Balance Coverage Requirements
Commercial LRBA refinancing is not subject to the 2026 residential restriction and continues under the existing compliance framework. Lenders treating commercial property loans require higher reserve levels than residential loans due to longer vacancy periods and higher tenant risk.
A fund refinancing a loan secured against a small retail property in Brisbane's Newstead industrial area with annual rent of $55,000 and a loan amount of $400,000 would typically need total member balances of at least $500,000 to meet most lenders' reserve requirements. Commercial tenancies in Brisbane's inner-city industrial precincts can experience vacancy periods of three to six months, and lenders require the fund to demonstrate it can cover loan repayments, body corporate fees, council rates, and insurance during that period without relying on contributions.
The balance level directly affects the maximum loan size the fund can support. A fund with $700,000 in balances refinancing the same property may be able to increase the loan to $450,000 to fund improvements or other fund expenses, whereas a fund with $350,000 in balances may be required to reduce the loan size on refinance to meet the lender's reserve ratio.
Fixed Rate Expiry and Balance Position at Refinance
When a fixed rate term expires and the loan reverts to a higher variable rate, the fund's balance position determines whether refinancing to a new fixed term or lower variable rate is viable. Funds that have drawn down balances to fund pensions or cover expenses during the fixed term may no longer meet the reserve requirements that applied at the original loan approval.
A fund that borrowed $320,000 three years ago with total balances of $450,000 may now hold only $380,000 in balances after paying a pension and covering property holding costs. If the fund seeks to refinance to avoid the revert rate, the lender reassesses capacity based on current balances, not the balance level at the original approval. The reduction in reserve coverage may result in a lower maximum loan amount or a requirement to inject additional funds into member accounts before the refinance can proceed.
This dynamic is particularly relevant for funds with members approaching pension phase, where balance levels decline over time due to minimum pension drawdowns. Refinancing capacity contracts as balances reduce, even when the property value remains stable or increases.
Arm's Length Terms and Member Balance Documentation
PCG 2016/5 sets out safe harbour terms for SMSF LRBAs, including interest rate benchmarks that apply regardless of when the arrangement commenced. A refinanced loan must meet arm's length terms to avoid having income assessed as non-arm's length income taxed at 45 percent.
Lenders document the fund's member balances through audited financial statements, member statements, and contribution records. The balance level used in the serviceability assessment must be verifiable and net of any pending withdrawals or pension payments. A fund with $500,000 in nominal balances but a pending pension payment of $80,000 will be assessed on the post-payment balance of $420,000.
Funds using related party guarantees to support the refinance must ensure the guarantee maintains the limited recourse character of the arrangement. The guarantor's recourse must be limited to the asset under the arrangement and cannot extend to other fund assets. Balance levels remain relevant even where a guarantee is provided, because the lender will still require the fund to demonstrate capacity independent of the guarantee.
Offset Accounts and Their Treatment in Balance Calculations
Genuine offset accounts offered by an authorised deposit-taking institution are not treated as a borrowing or a charge over fund assets under current ATO guidance. Funds refinancing to access an offset account can place reserve balances into the offset to reduce interest costs without affecting compliance.
An offset account linked to an SMSF loan allows the fund to hold reserves in a structure that reduces the effective interest rate on the loan while maintaining liquidity for fund expenses. A fund refinancing a $380,000 loan with $200,000 in accessible reserves can place those reserves into an offset account and reduce interest charges on $200,000 of the loan balance, lowering the effective rate and improving cashflow.
Not all SMSF lenders offer offset accounts, and those that do may require higher balance levels or limit offset access to variable rate loans. A fund with marginal balance coverage may not qualify for an offset account even where one is available, because the lender requires a minimum reserve level held outside the offset structure.

Frequently Asked Questions
How do member balances affect SMSF loan refinancing?
Lenders assess total member balances to determine if the fund has sufficient reserves to service the loan during vacancies and rate increases. Low balances relative to loan size can limit refinancing options and result in higher interest rates, even when equity in the property is adequate.
Can I refinance a residential SMSF loan after the 2026 restriction?
Refinancing an existing residential LRBA entered into before the commencement date remains permissible under the 2026 legislation, provided the refinance relates to the same asset and maintains the limited recourse character. Member balance levels still determine whether the refinance is approved based on serviceability and reserve requirements.
What reserve levels do lenders require for commercial SMSF loan refinancing?
Commercial SMSF loans typically require higher reserve levels than residential loans due to longer vacancy periods and tenant risk. Most lenders expect total member balances to be at least 20 to 30 percent above the loan amount, depending on property type and location.
Do offset accounts affect SMSF loan refinancing compliance?
Genuine offset accounts offered by authorised deposit-taking institutions are not treated as a borrowing or charge over fund assets under current ATO guidance. Funds can use offset accounts to reduce interest costs while maintaining liquidity, but not all lenders offer them and balance requirements may apply.
What happens if my fund balances have declined since the original loan?
If member balances have reduced due to pension payments or fund expenses, the refinance may be declined or require a lower loan amount to meet current reserve requirements. Lenders reassess capacity based on current balances, not the balance level at original approval.
