What documents do self-employed borrowers need for a low-doc home loan?

Two self-employed borrowers can earn similar incomes and still have completely different home loan experiences. The difference rarely comes down to how much they earn. More often, it comes down to how ready their paperwork is.

Lenders look for a clear, consistent picture across your ID, business registration, BAS (if you are GST-registered), bank statements, and accountant's letter. Present a clean file, and your application can move quickly. Leave gaps or inconsistencies, and it can stall for weeks.

In this blog post, we cover the exact low doc documents lenders typically ask for, how to prepare them, and the common mistakes that delay approval.

List of documents self-employed borrowers need for a low-doc home loan

Every lender has its own policy, and requirements vary between banks and specialist non-bank lenders. The number of BAS or months of bank statements required, in particular, can differ a lot from one lender to the next. The documents below are the ones most commonly requested. Treat this as your master checklist.

1. Identification documents

Every home loan application starts with proving you are who you say you are. This is a legal requirement for lenders under Australian anti-money laundering rules.

What you will typically need:

• Current Australian driver’s licence (front and back)
• Passport
• Medicare card
• Birth certificate or citizenship certificate (if requested)
• Proof of address, such as a recent utility bill or council rates notice

For visa holders, lenders will also ask for your visa details and passport, and some will want evidence of your work rights and residency status.

Tip: Make sure your documents are up to date and that the name on each one matches exactly. A middle name that appears on one but not the other can cause delays.

2. Business registration and structure documents

BAS only applies to GST-registered businesses. GST registration is generally required once your turnover reaches $75,000 a year, so if you are below that threshold and not registered, you won’t have BAS. In that case, lenders will usually rely more heavily on your business bank statements and accountant’s letter.

What you will typically need:

• ABN registration details: An ABN lookup printout showing your business name, status, and the date it became active
• ACN and ASIC company extract: If you operate through a company, this shows directors, shareholders, and the registration date
• Business name registration: If you trade under a name that differs from your own
• GST registration evidence: Many lenders look at how long you have been registered for GST, as it is a useful indicator of trading history
• Trust deed and any variations: If your business or investments sit within a family or unit trust
• Partnership agreement: If you operate in partnership with others
• Company constitution: Sometimes requested for more complex structures

Why it matters: The length of time your ABN has been active is often the first filter. If it hasn’t been active long enough (typically 12 to 24 months, depending on the lender), lenders may not consider your application, regardless of your income.

3. Business Activity Statements (BAS)

For most low-doc applications, BAS is the primary document lenders rely on. Because these statements are already lodged with the Australian Taxation Office (ATO) throughout the year, they give lenders lodged evidence of your business turnover without waiting for finalised tax returns.

BAS only applies to GST-registered businesses. GST registration is generally required once your turnover reaches $75,000 a year, so if you are below that threshold and not registered, you won’t have BAS. In that case, lenders will usually rely more heavily on your business bank statements and accountant’s letter.

What you will typically need:

• 12 months of lodged BAS (four quarterly statements or twelve monthly statements), though some lenders accept as few as 6 months while others ask for up to eight quarters
• Proof of lodgement, such as official ATO lodgement receipts or records downloaded from your ATO portal

How lenders assess it: Lenders focus on your total sales figure in the G1 field (which includes GST, so some lenders remove it first), then apply an industry-based expense ratio, which varies widely between lenders and industries, to estimate your net income. Consistent quarterly turnover with no sudden drops gives your application the strongest footing.

4. Business bank statements

Bank statements show the real flow of money through your business. They back up what your BAS says and show how your cash flow behaves day to day.

What you will typically need:

• 3 to 12 months of business transaction account statements, depending on the lender
• Statements for all business accounts, not just the main one
• In some cases, statements for any accounts linked to your sole trader or trust activity

Lenders examine these statements for:

• Regular, consistent deposits that line up with the turnover on your BAS
• Evidence that the business is actively trading
• Overdrawn balances, dishonoured payments or irregular patterns
• Large unexplained transfers

Tip: Where you can, run business income through a dedicated business account. Mixing personal and business transactions makes your income harder to verify.

5. Personal bank statements

Personal statements help lenders understand your living expenses, spending habits, and how your income reaches you.

What you will typically need:

• 3 to 6 months of personal transaction and savings account statements
• Statements for any offset accounts or joint accounts
• Evidence of regular transfers from the business to yourself, such as drawings or salary

Lenders use these to assess your living expenses and your financial conduct. Regular gambling transactions, frequent overdrafts, or buy-now-pay-later activity can all affect the outcome.

6. Accountant’s letter or declaration

This document often makes a low-doc loan possible by providing the lender with independent confirmation of your income from a qualified professional.

What it typically includes:

• Confirmation that the accountant has prepared your tax returns or financial statements (or has been your accountant for a set period)
• A statement of your estimated annual income for the business and for you personally
• Confirmation that your tax obligations are up to date
• The accountant’s registration details, such as their membership of CPA Australia, Chartered Accountants ANZ, or the Institute of Public Accountants (IPA), or their registration as a tax agent

Lenders usually accept a letter from a CPA, CA, IPA-qualified accountant or registered tax agent. Some also accept one from a registered BAS agent, and policies on this differ.

Be aware that some accountants are reluctant to provide these letters because of professional liability concerns, so confirm early that yours is willing to. Many lenders also have their own template or required wording, so ask your lender or broker for it first.

7. ATO documents

The ATO is the official record of your tax position, so lenders often ask for proof that you are in good standing.

What you will typically need:

• ATO integrated client account statement: Shows your income tax, GST, and PAYG balances
• ATO notices of assessment: For the last one or two years, if available
• ATO payment arrangement details: If you have a payment plan, lenders will want to see that it is current and being met

An ATO debt does not automatically rule you out, but an unmanaged or growing one is a serious concern for lenders. Policies vary, and some lenders will decline outright if the debt is large or not being managed. If you owe tax, it is better to be upfront and bring evidence of how you are managing it.

Behind on BAS or owe the ATO? Our accountants bring your lodgements up to date and structure a payment plan, ensuring your tax position is lender-ready before our lending team compare loans.

8. Tax returns and financial statements (if available)

One of the main attractions of a low-doc loan is that you don’t need to produce these. If you do have them, though, they can strengthen your application and may open up more lender options.

What you might provide:

• Personal tax returns for the last 1 to 2 years
• Company or trust tax returns
• Profit and loss statements
• Balance sheets

Even if the lender doesn’t require them, providing recent financials can sometimes get you a better outcome than the standard low-doc path. Where your returns are not yet lodged, an accountant-prepared profit and loss statement can often fill the gap.

9. Proof of deposit and genuine savings

Low-doc loans usually require a larger deposit than standard loans, and lenders want to see that the money is really yours.

What you will typically need:

• Savings account statements covering the past 3 to 6 months (or longer for some lenders)
• Evidence of funds from the sale of an asset, such as a contract of sale or settlement statement
• Gift letters if a family member is contributing, along with their bank statements
• Proof of equity in an existing property, if you plan to use it towards the purchase, such as a valuation and a current loan statement
• Records of any shares or other investments you intend to liquidate

Lenders also want to see enough funds to cover costs beyond the deposit, such as stamp duty, legal fees, and lender charges.

10. Assets and liabilities documentation

A lender needs a full picture of what you own and owe in order to assess your borrowing capacity.

Liabilities (money you owe):

• Credit card statements, plus the limits on each card (limits count even when the balance is zero)
• Personal loan, car loan for used and new cars, and equipment finance statements
• Existing home loan statements
• Buy-now-pay-later account details
• HECS/HELP debt balance
• Small business loans and overdraft facilities
• Any guarantor obligations you hold

Assets (what you own):

• Property ownership details
• Vehicle registration
• Superannuation statements
• Share portfolio statements
• Business assets and equipment lists

11. Property and purchase documents

Once you have found a property, the lender will need documents that relate to it. On a low-doc loan, lenders can’t lean on full financials to reassure them, so they pay extra attention to the property itself. It has to be a sound security for the loan.

What you will typically need:

• Contract of sale: Or a section 32 vendor’s statement in Victoria. Other states have their own disclosure documents, which usually come with the contract.
• Details of the property address and type: Such as a house, unit or townhouse. Some lenders limit lending on small apartments or rural land.
• Purchase price and deposit details: So the lender can confirm the loan amount and loan-to-value ratio (LVR). Low-doc loans often have a lower maximum LVR than standard loans.
• Refinance documents: Your current loan statement, most recent rates notice, and repayment history if you want to refinance your home loan. Your new lender will also arrange for the old loan to be discharged.
• For investment properties: A rental appraisal from a real estate agent or an existing lease agreement. Some lenders also want a recent rates notice and strata details for units.
• Construction documents: For construction home loans, lenders want a signed fixed-price building contract, council-approved plans and specifications, the builder’s licence and insurance details, and a schedule of progress payments. Funds are often released in stages as each stage of the build is completed.
• Building and landlord insurance: Most lenders want a certificate of currency before settlement.

The lender will also arrange a valuation to confirm the property is worth what you are paying for it, or, for a build, what it will be worth once complete. If the valuation comes in lower than the price, you may need a larger deposit or a different lender.

Lenders must also assess that a loan is suitable for you under Australian responsible lending laws. This is why they verify both your income documents and the property documents before approval.

12. Documents for specific situations

Depending on your circumstances, a lender might ask for additional paperwork:

• Company directors: Director guarantees, company financials and ASIC records
• Trust structures: Trust deed, trustee details and distribution statements
• Contractors and freelancers: Contracts, invoices or a letter from your principal clients
• New business owners: Evidence of your previous industry experience, a business plan, and any prior employment records. Options are usually limited to specialist non-bank lenders if you have been trading for less than 12 months.
• Sole traders not registered for GST: Business bank statements and an accountant’s letter, as you won’t have BAS to provide
• Foreign income earners: Overseas bank statements and income evidence, which may require certified translation
• Joint applicants: Full documentation for each applicant, including their income evidence

Use this as a quick reference before you apply:

Common documentation mistakes that delay low-doc home loan approvals

Many low-doc applications stall because of paperwork issues rather than low income, and most of these issues could have been avoided. Here are the seven most common ones.

1. Applying with unlodged BAS or tax returns

Lenders rely on your BAS to confirm your income, so a missing quarter leaves a gap in your 12-month history. Many lenders will pause or decline an application until that gap is filled, and unlodged returns can make your finances look disorganised.

Check your ATO online account for overdue lodgements before you speak to a lender. If you’re behind, ask your accountant to lodge everything first, then apply.

2. Figures that don’t match across documents

If your BAS shows one level of turnover, your bank statements show another, and your accountant’s letter states a third, lenders will notice. They cross-check everything, and even innocent differences, such as GST timing or income received in a different period, can appear to be inconsistencies.

Before submitting, line up your BAS, bank statements and accountant’s letter side by side. If the figures differ for a genuine reason, ask your accountant to write a short explanation and include it with your application.

3. Submitting out-of-date documents

Lenders want a current picture of your finances, so bank statements that are several months old or an accountant’s letter written long before you applied will usually be sent back. Many lenders only accept statements dated within the last 30 to 90 days.

Gather your documents close to the date you apply, and ask your lender or broker what “recent” means for them. If your application takes a while to process, be ready to supply updated copies.

4. Sending incomplete bank statements

Missing pages, blacked-out transactions, or summaries in place of full statements make lenders suspicious, even when you have nothing to hide. They need to see every transaction to assess your cash flow and spending habits. Download full statements directly from your internet banking as PDFs, with every page and every account included, and don’t edit or crop them.

5. Having unexplained deposits or transfers

A large amount appearing in your account just before you apply raises questions. It could be a loan, a gift, or a one-off payment, and lenders treat each differently when checking that your deposit is genuine savings and your income is real. Keep a paper trail for any large transaction, such as a sale contract, gift letter, invoice or tax refund notice. Where possible, avoid moving large sums around in the months before applying.

6. Applying before you meet the minimum trading period

Most low-doc lenders require that your ABN or GST registration has been active for a minimum period, commonly 12 months, but sometimes longer. This is often an automatic filter, so even a high income won’t help if your trading history falls short, and a declined application leaves an enquiry on your credit file.

Check your ABN and GST start dates on the ABN Lookup website, then confirm the lender’s minimum before you apply. If you’re only a few weeks short, waiting is usually smarter than applying early.

7. Leaving out debts or liabilities

Forgetting a credit card, a buy-now-pay-later account, a business loan, or a guarantee you gave someone else is a common slip-up. Lenders run a credit check and will find these anyway, so leaving them out damages trust and can slow or sink your application.

Even unused credit card limits count against your borrowing power. List every debt, including small ones, and include each card’s limit. It also helps to get a free copy of your credit report in advance so you know exactly what lenders will see.

Conclusion: Secure your low-doc home loan with ZedPlus

A low-doc home loan lets self-employed borrowers apply without full tax returns, provided the paperwork tells a clear, consistent story. When your ABN and GST registrations are active, your BAS (where applicable) is lodged, your bank statements match your turnover, and your ATO position is in order, lenders can see the real strength of your business.

Because low-doc loans generally carry higher rates, many borrowers use them as a stepping stone and refinance to a standard loan once their full tax returns are lodged. Mapping out that exit strategy with your broker from day one keeps your loan working for you over the long term.
