For self-employed borrowers, 2026 presents a tighter but still navigable lending environment. The Reserve Bank of Australia (RBA) holds the cash rate at 4.35%, keeping variable mortgage rates near 5.69% for new customers. Meanwhile, the Australian Prudential Regulation Authority (APRA) maintains a 3% serviceability buffer and, from February 2026, enforces a debt-to-income (DTI) cap of 6x for standard loans.
These conditions demand that self-employed applicants understand exactly how lenders calculate their assessable income. Unlike salaried workers with a single payslip, your borrowing power depends on tax returns, add-backs, and the documents you present.
This guide explains what lenders look for in 2026, how to maximise your assessed income, and which government schemes can help you get approved with a smaller deposit.
How lenders assess self-employed income in 2026
Australian lenders evaluate self-employed income by averaging your net profit over the most recent one to two financial years. They use tax returns, Notices of Assessment (from the ATO), and often business financial statements.
The two-year rule
Most lenders require at least two consecutive years of self-employment to demonstrate stability. In 2026, a sole trader or company director with less than two years of returns may still qualify through “low doc” loans, but those products typically carry interest rates 1% to 2% higher than standard variable rates. For maximum borrowing power, banks prefer to see a consistent or growing income stream.
Add-backs: The key to higher assessable income
Your tax return shows net profit after deductions. Lenders recognise that some deductions are non-cash or non-recurring and allow you to “add back” those amounts to increase your assessable income. Common add-backs include:
· Depreciation and amortisation · Interest on business loans (if separately disclosed) · Non-essential personal super contributions · One-off legal or accounting fees · Motor vehicle expenses (if not already capitalised)
For example, if your net profit is $80,000 and you claim $15,000 in depreciation, $5,000 in interest, and $10,000 in personal super contributions, your assessable income could rise to $110,000. That extra $30,000 can significantly boost your borrowing power.
Gross profit vs. net profit
Some lenders, particularly non-bank lenders, use gross profit minus a fixed “living expense” percentage. This is common for sole traders with high revenue but low net profit due to wages or other costs. The formula varies, but a typical approach is to take 70% of gross profit as assessable income. In 2026, this method can benefit borrowers whose net profit appears depressed due to large dividend payments or wage costs to family members.
Document checklist for maximum assessed income
Presenting the right documents upfront reduces processing delays and improves your chance of approval. Lenders in 2026 typically ask for:
· Last two years of personal tax returns and Notices of Assessment · Business tax returns and financial statements (profit & loss, balance sheet) for the same period · Two recent BAS (Business Activity Statements) – usually the last two quarters · A letter from your accountant confirming the business is ongoing and the figures are accurate · Bank statements for the business and personal accounts showing transaction history (often 3–6 months) · For company directors: ASIC company extract and proof of shareholding
Some lenders now accept digital income verification through your accounting software (Xero, MYOB). This can speed up assessment if you grant read-only access to the loan assessor.
Tip: If your net profit fluctuates, ask your accountant to prepare an “add-back schedule” that clearly lists all non-cash and non-recurring deductions. Banks like Westpac, NAB, and Commonwealth Bank accept well-documented add-backs from a qualified accountant.
The impact of APRA’s DTI cap and serviceability buffer
From February 2026, APRA’s DTI cap of 6x limits how much you can borrow relative to your assessable income. For a self-employed borrower with assessable income of $120,000, the maximum loan is $720,000 – even if serviceability calculations show you can afford more.
The 3% serviceability buffer also applies, meaning lenders must assess your ability to repay at a rate of 5.69% + 3% = 8.69%. This rate is used to calculate monthly mortgage repayments for the serviceability test.
How self-employed borrowers are affected
Self-employed borrowers often have higher non-mortgage expenses for business operations (e.g., vehicle costs, insurance, super). Lenders apply a base living expense (HEM, or Household Expenditure Measure) or use the actual expenses you report. In 2026, the HEM for a single person is around $20,000 per year, while a family of four may have a base of $40,000 to $50,000.
To pass the serviceability test at 8.69%, your total debt repayments plus living expenses must not exceed your assessable income. If your net profit is low after add-backs, you may struggle to meet the buffer. This is why maximising add-backs is critical.
First Home Buyer Guarantee changes from July 2026
Self-employed first home buyers can benefit from the First Home Buyer Guarantee (FHBG), which allows a 5% deposit without paying Lenders Mortgage Insurance (LMI). From July 2026, the scheme has two key changes:
· No income cap – Previously there were income limits ($125,000 for singles, $200,000 for couples). These are removed, allowing high-earning self-employed applicants to qualify. · Updated price caps – Maximum property prices increase to align with market values: · Sydney: $1.5 million · Brisbane: $1 million · Melbourne: $950,000 · Perth: $850,000 · Adelaide: $750,000 · Other capital cities and regional areas: varies
This is significant for self-employed borrowers who may have irregular income but a solid deposit. Because the FHBG uses your total income (including add-backs) for eligibility, a well-prepared application can secure a spot in the scheme.
Important: The FHBG is limited to 35,000 places per year, and demand is high. If you meet the criteria, apply early in the financial year.
Strategies to maximise borrowing power
Beyond add-backs, several strategies can raise your assessable income or reduce expenses to improve serviceability.
Reduce personal expenses
Lenders use the higher of HEM or actual living expenses. By minimising discretionary spending in the 3–6 months before application, you can lower the living expense figure that appears on your bank statements. For example, if you normally spend $80,000 a year on lifestyle, reducing to $60,000 for a few months can help.
Structure your business efficiently
If you operate as a company, consider taking a smaller director’s fee and retaining profits within the business. Some lenders treat retained profits as available income, but only if they are declared on your personal tax return. A company retaining $50,000 after paying you a $60,000 salary may result in a lower assessable income than if you paid yourself the full $110,000. Work with an accountant to find the right balance.
Use a mortgage broker
A broker can compare up to 40 lenders and identify those with the most favorable add-back policies or gross profit calculation methods. In 2026, brokers also know which lenders are more flexible with the DTI cap – some non-bank lenders offer up to 7x DTI for self-employed borrowers with strong credit.
Consider a joint application
Adding a partner with stable PAYG income can lift your combined serviceability and reduce the impact of income fluctuations. Even if the partner earns modestly, every dollar counts under the DTI cap.
Common mistakes self-employed borrowers make
· Not providing BAS statements – Lenders often require BAS to verify ongoing income beyond tax returns. Missing BAS can lead to a lower assessment or outright decline.
· Switching accountants or business structures too soon – Changing from sole trader to company just before applying can trigger a “less than two years” review, forcing you into a higher-rate loan.
· Claiming maximum deductions – While tax-efficient, heavy deductions (e.g., new equipment, large super contributions) reduce net profit. If you plan to borrow within 12 months, consider deferring large deductions.
· Ignoring the DTI cap – Even with a high income, exceeding a 6x DTI will cap your borrowing. Plan your purchase price accordingly.
FAQ
Q: If my net profit is $70,000 but I have $20,000 in add-backs, what is my assessable income?
A: Typically $90,000. Most lenders accept common add-backs like depreciation, interest, and non-essential super contributions. Always provide an accountant’s letter to support the add-backs.
Q: Can I use the First Home Buyer Guarantee with a 5% deposit if my income is irregular?
A: Yes. The FHBG uses your total assessable income (including add-backs) and has removed income caps from July 2026. As long as you meet the price cap (e.g., $1.5M in Sydney) and have not owned property in Australia before, you are eligible.
Q: How does the 3% serviceability buffer affect my borrowing power?
A: Lenders assess your ability to repay at a rate of 8.69% (current variable rate of 5.69% plus 3%). For a $500,000 loan over 30 years, the monthly repayment at 8.69% is about $3,900. Your total debts plus living expenses must be less than your assessable income.
Q: What if I have only one year of tax returns? Can I still get a home loan?
A: Yes, but you may be limited to low doc loans with higher rates (around 6.5%–7.5%). Some lenders accept one year of returns if you have a strong accountant reference and a history of consistent income from previous employment in the same industry.
