“What you need to show is not just income. It is consistency, stability, and the ability to service a loan even if revenue fluctuates.” [cite: 806]
A self-employed mortgage application is fundamentally about demonstrating to the lender that your income is genuine, consistent, and likely to continue. [cite: 807] The documents are the mechanism for doing that, but the underlying story your financials tell is what actually drives approval. [cite: 808]
Income evidence
- For full-doc: two years of personal tax returns with ATO Notices of Assessment, business financial statements, and business tax returns. [cite: 810]
- For alt-doc: four consecutive BAS statements, supported by an accountant’s letter and six to twelve months of business bank statements. [cite: 811]
How lenders calculate your income
Lenders typically take an average of your last two years of net income from the tax returns. [cite: 813] If income is growing, some lenders will use the most recent year. [cite: 814] If income has declined, most lenders will use the lower figure or the two-year average. [cite: 815] Legitimate tax deductions reduce your taxable income and therefore the income figure lenders will accept. [cite: 816] Some lenders add back certain non-cash deductions like depreciation to arrive at a higher assessable income. [cite: 817]
Business stability and tenure
Most major banks require a minimum of two years of ABN registration and two full financial years of trading before assessing a self-employed application under standard criteria. [cite: 819] Some non-bank lenders will consider applications with one year of ABN history where supporting documentation is strong and the deposit is sufficient. [cite: 820]
Clean credit and a manageable DTI
A clean credit history and a manageable Debt-to-Income ratio matter here as much as for PAYG borrowers. [cite: 822] Outstanding business debts, ATO payment plans, or high business liabilities all affect the assessment. [cite: 823] Clearing or restructuring business debts before applying is often worthwhile. [cite: 824]
You may consider seeking independent advice from a licensed mortgage broker or financial professional to assess your personal circumstances. [cite: 825] This is general information only. This information is general in nature and does not take into account your objectives, financial situation or needs. [cite: 826] Self-employed mortgage assessment criteria and add-back policies vary by lender. Speak with a licensed mortgage broker experienced in self-employed lending. [cite: 827] All loans are subject to lender approval. [cite: 828]
