Self-employed income and the banks.
William Sun · May 2026
Self-employed borrowers consistently overestimate how hard it is to get a loan, and consistently underestimate how much the lender choice matters. The first misconception delays applications that would have succeeded. The second puts people with serviceable income into products that don't fit them — or keeps them at a lender that assessed their income most conservatively when a better option existed.
The underlying issue is that lenders don't take a business owner's income at face value. They can't — business income is structurally different from a salary. It can vary year to year, it can be drawn from the business in different ways, and tax minimisation strategies that are entirely legitimate can make income look lower than it actually is. Each lender has its own methodology for interpreting that income, and those methodologies produce meaningfully different borrowing capacity assessments from the same set of documents.
How lenders read self-employed income
The standard requirement is two years of personal tax returns and notices of assessment, plus two years of business financials — profit and loss statements and balance sheets, either prepared by an accountant or extracted from the business's tax returns. The lender uses these to construct an assessable income figure.
How they construct it varies. Some lenders average the two years of net profit. Some take the lower of the two years. Some add back certain non-cash deductions — depreciation, amortisation — to arrive at a more accurate picture of actual cash available for loan servicing. Some will accept one year of strong returns if the trend is improving and the business has been operating for longer than two years. Some won't.
The treatment of company structures adds another layer. A borrower who pays themselves a modest salary from a company they own but retains significant profit in the business may have an income assessment that looks very different from what they actually draw. Some lenders will recognise retained profit; others assess only the salary. This single variable can shift borrowing capacity by hundreds of thousands of dollars.
What the documents need to show
ABN and GST registration
The ABN must have been active for at least 12 months — most lenders require 24. GST registration is typically required for businesses turning over $75,000 or more. The registration date matters; lenders will verify it independently.
Two years of personal tax returns and NOAs
The notice of assessment confirms what was lodged with the ATO. Lenders cross-reference the figures. If there's a discrepancy between the tax return and the NOA, it raises questions. If the most recent year's return hasn't been lodged, some lenders won't proceed — others will, with conditions.
Business financials
Profit and loss statements prepared by a registered accountant carry more weight than internally produced documents. If your accountant produces financials specifically for the loan application, they need to be consistent with the tax returns — any variance creates a documentation problem that slows or stops the application.
Business bank statements
Six months of business transaction account statements are typically required. Lenders are looking for consistent revenue, no unexplained large withdrawals, and a pattern of inflows that supports the income figure in the financials. Seasonal businesses should be prepared to explain seasonality; a nine-month revenue drought followed by a strong quarter can look like instability to an assessor who doesn't know the industry.
When the full-doc path isn't available
Some self-employed borrowers can't provide two years of financials — a business that's 14 months old, a recent change in structure, a period of significant one-off expenditure that depresses the profit figure. In these situations, the full-doc path either closes or produces a poor income assessment.
Alternative documentation loans — sometimes called alt-doc — allow the borrower to evidence income using different documentation: 12 months of business bank statements, a signed accountant's letter, BAS statements. The trade-off is typically a higher interest rate and a lower maximum LVR. The lender is accepting more documentation risk and pricing accordingly.
Alt-doc is not a workaround for borrowers who can't service the loan. The income still needs to be real. What it addresses is the documentation gap between real income and the income a standard two-year tax assessment would recognise — which, for a growing business in its early years, can be substantial.
The lender that assesses your income most fairly is not always the one with the lowest rate. For self-employed borrowers, the lender choice — and the structuring of the application — often matters more than the margin difference between the top few products on the panel. A lender that recognises add-backs and retained profits may assess your borrowing capacity at $300,000 more than one that doesn't. That's the conversation to have before you apply anywhere.
