Tier 3 of 3
Low doc
The least documentary evidence a lender will accept while still meeting its responsible lending obligations — typically a self-declaration supported by one corroborating source rather than several.
You land here when
- Shorter trading history, or a genuinely irregular income pattern
- Income that can be corroborated but not fully documented
- Borrowers who have exhausted the tiers above rather than skipped them
Documents to assemble
- A signed income self-declaration
- At least one corroborating source: BAS, an accountant's letter, or business bank statements
- Evidence the ABN is active and how long it has been
- Full disclosure of existing debts and commitments
What this tier costs you
The highest pricing of the three, the tightest loan-to-value ratio, often a risk fee, and the smallest lender panel. It is a route, not a shortcut — and a lender still has to reasonably verify your position, so "no documents at all" is not a thing that exists.
Where the rules come from
General information about how Australian lenders assess self-employed income. Lender policy differs and changes, and tax and lodgement rules are set by the ATO; each page links to the body that sets the rule. Reviewed 17 August 2026.
The other tiers
Full doc Your income proven from lodged tax returns and the ATO notices of assessment that confirm them, for two financial years. Alt doc Your income evidenced from business activity statements and business bank statements instead of lodged returns, usually with a declaration you sign and an accountant confirms.
