Sole traders face stricter documentation requirements when refinancing than salaried employees, but meeting those requirements is straightforward when you know what lenders assess and how they calculate your income.
The key difference is proof of consistent earnings. Where a PAYG employee provides recent payslips, you'll typically need two years of tax returns plus a recent profit and loss statement. Lenders use these to calculate your assessable income, which determines how much you can borrow and whether you meet their serviceability criteria. Most will average your declared income across the two most recent financial years, though some take your most recent year if it's higher. That calculation drives every other part of your refinancing application.
Why Lenders Assess Sole Trader Income Differently
Lenders view sole trader income as variable because it depends on ongoing business performance rather than a fixed salary. They average your net profit after business expenses, add back certain non-cash deductions like depreciation, and apply that figure to their serviceability calculator. This approach protects both you and the lender by ensuring repayments remain affordable even if your income fluctuates.
Consider a sole trader in Marrickville who runs a digital marketing consultancy. Their tax returns show $92,000 net profit in the first year and $108,000 in the second. The lender averages those figures to arrive at $100,000 assessable income, then applies their serviceability buffer to determine the maximum loan amount. If the current year profit and loss shows income tracking above the two-year average, some lenders will use the higher figure, but they'll still want evidence that the increase is sustainable rather than a one-off project.
Documents Required for a Sole Trader Refinance Application
You'll need two full years of individual tax returns including the ATO Notice of Assessment for each year. These prove your declared income and confirm the returns were lodged. A profit and loss statement for the current financial year, typically covering the most recent quarter or six months, shows lenders your business is still generating consistent revenue. If you're registered for GST, they'll also request your Business Activity Statements.
Most lenders ask for 12 months of business bank statements to verify the income declared in your tax returns and profit and loss. They're looking for regular deposits that align with your reported turnover, not hunting for minor discrepancies. If your business banking and personal banking are mixed, separate statements for both accounts will be required. The application will also include standard identification, a current property valuation, and details of your existing loan.
How Your ABN Age and Trading History Affect Approval
Lenders typically require your ABN to be registered for at least two years before they'll assess your sole trader income. This aligns with the two-year tax return requirement and demonstrates that your business has moved beyond the startup phase. If your ABN is newer than two years but you were previously employed in the same field, some lenders will consider a combination of your employed income and sole trader earnings, though this reduces your borrowing capacity compared to using two full years of self-employment.
A graphic designer in Newtown who left a salaried role to freelance 18 months ago won't yet meet the standard two-year requirement for most lenders. They could wait another six months and lodge their second tax return, or approach a lender willing to assess one year of sole trader income combined with their final year of PAYG employment. The second option usually results in a lower assessable income figure because lenders apply a heavier discount to single-year self-employment earnings.
Improving Your Serviceability Before You Apply
Reducing personal expenses on your bank statements improves how lenders assess your capacity to service a loan. Regular gambling transactions, frequent Afterpay or buy-now-pay-later commitments, and high discretionary spending all affect your application. Lenders apply a minimum living expense benchmark, but if your actual spending exceeds that figure, they'll use the higher amount in their calculations.
Paying down credit card limits or closing unused accounts increases your borrowing capacity even if you don't carry a balance. Lenders assume you could draw the full limit at any time and factor that potential debt into their assessment. A sole trader with two credit cards totalling $30,000 in available limits might see their maximum loan amount drop by $150,000 compared to having no cards at all, depending on the lender's assessment rate.
If you've recently lodged a tax return that shows lower income due to business deductions or a quieter year, waiting until the next return is lodged can improve your application. Lenders average the two most recent years, so a stronger second year lifts that average. You can review your current position and likely serviceability outcome with a loan health check before deciding whether to apply now or wait.
Equity Position and Loan-to-Value Ratio Requirements
Your equity position determines whether you'll pay Lenders Mortgage Insurance and affects which lenders will consider your application. Most lenders assess sole traders at a maximum LVR of 80% without LMI, meaning you need at least 20% equity in your property. Some will extend to 90% or 95% LVR for self-employed borrowers, but this usually requires a strong income history, excellent credit, and higher interest rates.
If you're refinancing to access equity for investment or business purposes, the amount you can release depends on your assessable income and the lender's maximum LVR for your borrowing purpose. Equity release for investment property purchases is generally assessed at 80% LVR, while cash out for business use might be capped lower depending on the lender's appetite for that scenario.
When a Fixed Rate Period Ending Creates Urgency
Sole traders coming off a fixed rate need to start their refinancing application at least eight to twelve weeks before expiry if their income structure requires full documentation. Leaving it until the final month rarely works because lender assessment timeframes stretch longer for self-employed applicants, particularly if they request additional documents or clarification on your profit and loss.
The risk of waiting is reverting to your lender's variable rate, which might sit well above the rates available through refinancing. A sole trader in Leichhardt whose fixed rate expired in late spring reverted to a variable rate of 6.8% when refinance rates were available from 6.1%. The delay in preparing their tax returns and profit and loss meant they paid the higher rate for three months while their application processed, costing roughly $1,400 in additional interest on a $600,000 loan.
Credit History and How Lenders Assess Risk
Your credit file affects your application regardless of employment type, but sole traders have less margin for error because lenders already view self-employment as higher risk. Late payments, defaults, or multiple credit enquiries in the past 12 months can result in a decline or a higher interest rate. Most lenders will accept a clear credit history with no defaults in the past five years and no more than one or two late payments in the past two years.
If you've had credit issues in the past, some lenders specialise in assessing applications outside the standard criteria, though their rates are higher. Addressing any outstanding defaults and ensuring your current commitments are paid on time for at least six months before applying improves your options. Lenders can request a copy of your credit file during the application, so reviewing it yourself first through a free service lets you identify and address issues before they delay your approval.

Frequently Asked Questions
How many years of tax returns do sole traders need to refinance?
Most lenders require two full years of individual tax returns with ATO Notices of Assessment. Some will accept one year of sole trader income combined with a final year of PAYG employment if your ABN is less than two years old, though this usually reduces your borrowing capacity.
Can I refinance if my most recent tax return shows lower income?
Lenders average your net profit across the two most recent financial years, so one lower year will reduce your assessable income. If your current year profit and loss shows income has recovered, some lenders will consider the higher figure, but waiting until your next return is lodged often improves your serviceability.
Do sole traders need a larger deposit to refinance?
Most lenders assess sole traders at a maximum 80% LVR without Lenders Mortgage Insurance, meaning you need at least 20% equity. Some lenders will extend to 90% or 95% LVR for self-employed borrowers, though this typically comes with higher interest rates and stricter income verification.
How long does a sole trader refinance application take?
Sole trader applications typically take eight to twelve weeks from submission to settlement because lenders require additional income verification. Starting your application well before a fixed rate expiry or target settlement date reduces the risk of delays that cost you money.
What happens if my business and personal banking are in the same account?
Lenders will accept statements from a mixed-use account, but you'll need to provide both business and personal transaction history. Separating your banking before applying makes the assessment clearer and faster, though it's not mandatory if your current setup has been consistent for the past two years.
