Quick answer
A full doc loan proves income with standard documents such as payslips or two years of tax returns. A low doc loan uses alternative evidence, such as business bank statements, BAS or an accountant's letter, and suits self-employed borrowers whose tax returns do not show their true cash flow. Both still require lenders to be satisfied you can repay.
Key points
- Full doc relies on payslips, tax returns and notices of assessment.
- Low doc relies on alternative evidence such as bank statements, BAS and accountant letters.
- Low doc loans are not no-questions loans; lenders still assess ability to repay.
- Which suits you depends on your income type, paperwork and how recent your business is.
What is the difference between low doc and full doc?
Both types of loan answer the same question: can you repay? The difference is how you prove it.
A full doc loan uses the standard documents lenders know best. For an employee, that means payslips and a notice of assessment or group certificate equivalent. For a self-employed borrower, it generally means two years of personal and business tax returns and notices of assessment.
A low doc loan, short for low documentation, accepts alternative evidence when the standard papers do not tell the full story. Those alternatives vary by lender but commonly include business activity statements, business bank statements, an accountant’s letter and a declaration of income.
Neither route skips the lender’s assessment. Lenders still look at your credit file, existing commitments, living costs and the property. Low doc is about how income is evidenced, not whether it is assessed.
How do they compare?
| Feature | Full doc | Low doc |
|---|---|---|
| Main income evidence | Payslips, tax returns, notices of assessment | BAS, bank statements, accountant letter, declaration |
| Best suited to | Employees and established self-employed with clear returns | Newly self-employed, contractors, owners with complex returns |
| Paperwork effort | Often lower if your files are in order | Depends on how available alternative evidence is |
| Lender choice | Broad | Narrower, more specialist |
| Assessment | Reasonable inquiries and verification | Reasonable inquiries and verification |
| Typical issue | Returns may understate real cash flow | Lenders may want a longer trading history or strong bank data |
Note that we do not give any pricing comparison here. Pricing varies with the borrower, the security and the lender, and it is not appropriate to generalise.
Why would someone choose low doc?
Self-employed income often looks different on paper than in the bank account. Legitimate deductions can lower taxable income. A business may be young, with only one return. Returns may be lodged late. A contractor may have changed clients mid-year. None of this means the borrower cannot afford the loan, but a rigid full doc assessment can struggle to see it.
Low doc lets the lender consider other evidence. A year of consistent business bank deposits, regular BAS lodgements and a letter from the accountant can paint a convincing picture. See our pages on low doc loans, bank statement business loans and low doc business loans for how this plays out in different loan types.
What are the downsides of low doc?
- Fewer lenders offer it, so there is less choice.
- Stricter conditions can apply, such as a minimum trading history or a lower maximum loan to value ratio.
- Cost differences may apply, since lenders see a different risk profile.
- Evidence still matters. Poorly organised bank statements or lapsed BAS lodgements can weaken a file.
- It is not for everyone. If you can provide full doc paperwork easily, that route may be simpler.
A good broker will check whether a full doc option exists before moving to low doc, and will tell you honestly if it does.
What documents might I need for low doc?
Lenders differ, but commonly requested items include:
- Business activity statements, which the ATO explains how to lodge and obtain through its online services or your registered tax agent. Our guide on BAS and financial statements covers it.
- Business and personal bank statements. See how to get bank statements for a loan.
- An accountant’s letter confirming your income and trading history, explained in our guide on accountant’s letters.
- ABN registration details and proof of how long you have operated.
- Identification and details of your assets and liabilities.

Does low doc apply beyond home loans?
Yes. The idea of alternative evidence shows up across several areas:
- Business loans: bank statement and BAS-based assessments. See low doc business loans.
- Rural loans: farm income can be seasonal or lumpy, so low doc farm loans look at different evidence.
- Private mortgages: private lenders often focus on the security and exit, which is covered under low doc private mortgages.
- Alternative documentation more broadly: see no doc and alt doc home loans for how lenders treat applications with minimal paperwork.
The principle is consistent. Whatever the evidence, lenders must still be satisfied about repayment.
An illustrative example
This is an illustrative scenario only.
A graphic designer has been self-employed for about eighteen months. Her first tax return shows modest taxable income because she claimed equipment and home office deductions. Her bank statements, however, show steady client payments, and her BAS lodgements are up to date. A full doc lender sees the return and hesitates. A low doc lender looks at the bank data, the BAS and a letter from her accountant and sees reliable cash flow.
Her broker explains both options, checks whether any full doc lender would consider her and then submits to a lender whose low doc policy fits. No outcome is guaranteed, but the right evidence helped the right lender see the right picture.
What mistakes should I avoid?
- Assuming low doc means a loan without checks.
- Skipping lodgement of BAS or tax returns, then trying to catch up at the last minute.
- Mixing personal and business spending in one account.
- Submitting statements from several accounts without explaining them.
- Choosing low doc when full doc was available and simpler.
- Overstating income on any declaration. Accuracy matters.

Frequently asked questions
What is a full doc loan?
It is a loan where you prove your income with standard documents, typically payslips, tax returns and notices of assessment for employees, or two years of personal and business tax returns for self-employed borrowers. It is the standard route and suits people whose paperwork clearly shows their earnings.
What is a low doc loan?
It is a loan for borrowers who cannot easily provide the standard documents, often self-employed or contractors. Instead of full tax returns, the lender may accept other evidence such as business activity statements, business bank statements or an accountant's declaration. The borrower still has to show they can afford repayments.
Do low doc loans mean no checks?
No. Lenders still make inquiries and look at your credit file, existing debts, living expenses and the security. Low doc changes the type of income evidence, not the need for the lender to be satisfied about repayment. Be wary of anyone promising approval with no questions.
Who should consider a low doc loan?
Common examples include newly self-employed people, business owners whose tax returns are lodged late or show low taxable income after deductions, contractors and gig workers. It can also suit anyone whose paperwork is incomplete. A broker can tell you whether a full doc option exists before you choose low doc.
How do I get the documents for a low doc loan?
Business activity statements can be obtained through your ATO online services or your registered tax agent, bank statements through your bank and accountant letters from your accountant. Our guides on BAS, bank statements and accountant letters walk through each step so you can have them ready before you apply.
