If you work for yourself, proving a regular income for a home loan can feel like a hurdle. Alt-doc loans—short for alternative-documentation loans—are designed to help self-employed borrowers demonstrate their financial position using records that go beyond traditional payslips and employer tax returns. Think of them as a flexible pathway, and knowing which documents are available makes the journey clearer.
What Are Alt-Doc Loans?
An alt-doc loan lets you support your borrowing application with documents that reflect the way your business actually runs. Instead of a single group certificate, you might show a mix of business activity statements (BAS), bank statements, accountant letters, or tax returns. Lenders use these to build a picture of your capacity to repay, while still applying their own credit criteria.
Which Alternative Documents Are Commonly Accepted?
When you explore an alt-doc loan, you will generally see four main document types. Not every lender wants the same blend, but most will consider some combination of the following.
1. Business Activity Statements (BAS)
BAS records are lodged quarterly (or monthly) with the ATO and show your gross income, GST collected, and taxes payable. Lenders often look at a series of BAS—say, the most recent four quarters—to gauge your revenue trend. If your income fluctuates, a rolling set of BAS can smooth out seasonal peaks.
2. Business Bank Statements
Regular bank statements give a real-time view of your cash flow. Lenders typically ask for the last six to twelve months and focus on consistent credits coming into your business account. They might annotate large irregular deposits so the assessment isn’t skewed by a one-off payment.
3. Accountant Letters
A signed letter from your registered accountant or tax agent can verify your income and confirm that your business is trading viably. This is useful when your business structure makes it hard to isolate personal drawings, or when your tax returns contain write-offs that don’t reflect your actual spending power. Bear in mind that lenders still cross-check these letters with other documents.
4. Tax Returns
Even under an alt-doc pathway, two years of personal and business tax returns are often requested. Returns show your taxable income after deductions, so if you legitimately claim many expenses, the figure on paper may feel lower than your real cash flow. That’s where pairing returns with bank statements or BAS can help.
Which Combination Works Best?
There is no single perfect bundle. The right mix depends on how your income is structured and what the lender asks for. Some scenarios to consider:
- Steady revenue with clear BAS history: BAS plus bank statements often give a reliable picture for a sole trader or small partnership.
- Complex business structure: Tax returns accompanied by an accountant letter can explain trusts, companies, or distributions that don’t show up neatly on personal returns.
- High turnover but low taxable profit: Bank statements paired with an accountant letter may demonstrate serviceability that a tax return alone would hide.
When you compare options, small differences in interest rates, fees, and repayment structures can add up over the life of the loan. Using resources like Moneysmart’s home loan guides can help you weigh what matters, from the features of an offset account to the trade-offs of an interest-only period. Their step-by-step pages cover everything from choosing a loan to what to do if repayments become difficult—worth reading before committing.
Working Through an Alt-Doc Application
Approaching an alt-doc loan is about preparation. Start by gathering at least the last couple of years of financial records, even if the lender only asks for one. Having extra data can speed up the conversation. Because different institutions have different appetites for self-employed lending, comparing policies and rates across several lenders is important. A mortgage broker can explain what various lenders look for and help you present your documents clearly, although the ultimate decision always rests with the credit provider.
Remember that no one can guarantee approval, a specific rate, or a set saving just by submitting alternative documents. Lenders take into account your overall financial position, the property itself, and market conditions at the time of assessment.
Getting Started
