What Is a Low Doc Home Loan?
A low doc (low documentation) home loan is designed for borrowers who can't provide the standard income evidence required by mainstream lenders, typically self-employed people, contractors, sole traders and business owners whose taxable income doesn't reflect their true financial position. Instead of full tax returns, low doc loans accept alternative documentation to verify income.
The term "low doc" is slightly misleading, it's not low documentation overall, it's alternative documentation. You still prove your income; you just prove it differently. The key is matching your documentation type to the right lender's policy. Some lenders accept BAS statements; others accept accountant declarations; others self-certification with a statutory declaration. Knowing which lender to use for which documentation type is where the broker expertise lies.
Who Uses Low Doc Loans?
- Self-employed business owners whose taxable income is reduced by legitimate deductions
- Sole traders and contractors with variable income
- Investors with complex income structures
- People recently self-employed (less than 2 years ABN history)
- Those returning to self-employment after employment
Alternative Documentation Types
BAS Statements (Most Common)
Business Activity Statements for the last 12 months. Lenders use your declared GST turnover to estimate income. Most preferred by lenders, verifiable through the ATO.
Accountant Declaration
A letter from your accountant declaring your income for the current or most recent financial year. Acceptable at many lenders, the accountant's professional reputation backs the declaration.
Bank Statements
6–12 months of business bank statements showing deposits (turnover). Lenders apply a shading factor to determine net income. Most common for service-based businesses with clean deposit patterns.
Self-Certification
A statutory declaration from the borrower declaring their income. Higher risk for the lender, accepted by a smaller number of specialist lenders, typically with higher LVR restrictions and rate premiums.
Key Requirements for Low Doc Loans, 2026
- ABN history: Typically 2+ years registered (some lenders accept 1 year)
- GST registration: Required by most lenders if turnover exceeds $75,000
- Deposit: Typically 20–30% (LVR 70–80%), limited low doc products at 90%+
- Clean credit: Most low doc products require clean credit history, non-conforming low doc exists but carries higher rates
- Property type: Standard residential, non-standard properties further restrict options
Rate Premium for Low Doc
Low doc loans carry a rate premium of approximately 0.3–0.8% above equivalent full-doc loans from the same lender. The premium reflects the additional income verification risk. As your ABN history lengthens and your tax returns accumulate, transitioning to full-doc (and the lower rate) is usually achievable.
Transitioning from Low Doc to Full Doc
Once you have 2 years of full tax returns showing your actual income, you typically qualify for full-doc lending, at lower rates and with more lender options. Many clients start with low doc, build their documentation history over 2 years, then refinance to full-doc. We plan this transition from day one.
