Most self-employed borrowers assume low doc is the compromise option — the one you take when you can’t qualify for the real thing. That’s not quite right. For a lot of ABN holders, low doc produces a better outcome than full doc would have, and for some, full doc is genuinely the better choice.
Here is how to tell which camp you’re in.
The Core Difference
Full doc means the lender verifies your income from primary documents: two years of personal and business tax returns, notices of assessment, and usually financial statements. They calculate your capacity precisely and price accordingly.
Low doc means the lender substitutes other evidence — ABN and GST history, business bank statements or BAS, and the asset itself — for tax returns.
No doc, at the far end, means no income evidence at all, generally supported by property equity.
The lending itself is the same. What differs is how the lender satisfies itself that you can pay.
Side by Side
| Low doc | Full doc | |
|---|---|---|
| Tax returns required | No | Yes, usually two years |
| Financial statements | No | Usually |
| Typical documents | ABN, BAS or bank statements | Tax returns, NOAs, P&L, balance sheet |
| Time to approval | Often 24 hours | Days to weeks |
| Interest rate | Generally slightly higher | Generally slightly lower |
| Suits | Recent returns understate income; returns not yet lodged; speed matters | Returns show strong income; time is not pressing |
| Maximum | Up to $500,000 through CarFund | Varies by lender |
When Low Doc Is Genuinely the Better Choice
Your tax returns understate what you earn
This is the most common situation and the most important one. Good tax planning minimises taxable income. A full doc lender reads that minimised figure as your actual capacity, and lends accordingly.
If your last return shows $60,000 of taxable income on a business turning over $400,000, full doc will limit you to what $60,000 supports. Low doc looks at the business rather than the return, and frequently produces a larger approval — not a smaller one.
Borrowers are often surprised by this. Low doc isn’t always the lesser option; sometimes it’s the only one that sees your business accurately.
Your returns aren’t lodged yet
If you’re mid-year, or your accountant hasn’t finalised last year, full doc simply isn’t available until they are. Low doc doesn’t wait.
You need to move quickly
An EOFY purchase, an auction, a vehicle that won’t sit around, a truck that broke down on Tuesday. Full doc assessment takes as long as it takes. Low doc pre-approval is frequently within 24 hours.
Your income is lumpy or seasonal
Farming, construction milestones, project work. A single year’s return can look alarming out of context. Bank statements over six months tell a fairer story.
Your structure is complicated
Trusts, multiple entities, partnerships, related-party arrangements. Full doc assessment of a complex structure is slow and often ends conservatively. Low doc sidesteps much of it.
When Full Doc Is the Better Choice
Be honest about these — going low doc when full doc suits you costs money for no reason.
Your returns look strong
If your last two returns show healthy taxable income and you have the documents ready, full doc will generally price better. Take the cheaper option.
You’re borrowing a large amount
Above roughly $150,000, most lenders reintroduce income verification regardless. If you’re heading into that territory with good documents available, full doc from the start is cleaner than a low doc application that turns into a documented one anyway.
You have time and no urgency
If the purchase is three months away and your accountant can produce everything, use the time.
You want the absolute lowest rate
Full doc, clean credit, strong returns, mainstream vehicle. That combination gets the best pricing available, and no structuring trick beats it.
The Rate Difference in Context
Low doc pricing sits above full doc pricing. The margin is usually smaller than people assume, and it is frequently outweighed by two things:
- Approval size. A larger low doc approval that lets you buy the right vehicle beats a smaller full doc approval at a slightly better rate on the wrong one.
- Timing. A vehicle bought before 30 June, or an auction lot secured, can be worth more than the rate difference over the term.
Neither of those is an argument for ignoring the rate. They are an argument for comparing outcomes rather than comparing rates in isolation.
What Both Have in Common
Whichever you choose, the structure options are the same — chattel mortgage, finance lease or commercial hire purchase — and so is the tax treatment. A chattel mortgage on a business-use vehicle generally allows a GST claim on the purchase price for GST-registered businesses, with interest and depreciation deductible in proportion to business use. Your accountant should confirm your specific position.
Credit history matters equally in both. Vehicle age and type matter equally in both. Property equity helps in both.
Frequently Asked Questions
Can I start low doc and switch to full doc?
In practice you’d withdraw and reapply, which means a second enquiry on your file. Better to decide up front — which is exactly what a broker conversation is for.
Does low doc mean a smaller loan?
Not necessarily, and often the opposite for borrowers whose tax returns understate their income.
Is low doc harder to refinance later?
No. Plenty of our clients refinance into better pricing after two years of clean conduct.
Do I need to be GST-registered?
Not always, but GST registration and a longer ABN history put you in a better tier with most lenders.
Which will you recommend?
Whichever produces the better outcome for your file. If your returns are strong and you have them ready, we’ll say so.
Not Sure Which Applies to You?
That’s a five-minute conversation, not a research project. Tell us your ABN age, whether you own property, roughly what the returns show and what you’re buying, and we’ll tell you which route makes sense.
