Sole Trader Home Loan · Requirements · Documents
Say you have traded under your own name for a few years and the business is going well. Then a lender asks for documents you have never had to think about. Here is what goes on a sole trader's home loan file, how the income is read, and what to fix before you apply.
Quick Answer
Lenders want a sole trader to show an active ABN, usually two lodged tax returns with notices of assessment, and recent BAS or bank statements, though low doc lenders can work with less. If your returns are behind or show less than you really earn, a one doc home loan can work from a single income document, and the sole trader structure itself is never the problem.
Also called: sole trader home loan, home loan for sole traders, sole trader mortgage. They describe the same thing: a standard home loan, assessed on income you earn through your own ABN.
Can a sole trader get a home loan in Australia?
A sole trader can get a home loan in Australia, from banks and non-bank lenders alike, as long as the file shows a real business, a steady income and the documents to prove both. What changes is where the income comes from. There is no payslip and no employer to call, so the lender reads your income from your own tax return.
That works because a sole trader and the business are the same legal person. Your personal return is the business's income. The profit you made under your ABN lands on your individual return, and that line is the number the lender starts from when it tests serviceability.
From there, sole traders take one of two routes. A full doc loan uses lodged returns and notices of assessment, and usually gets the sharpest pricing and highest LVR. A low doc home loan uses BAS, business bank statements or an accountant letter where the returns are behind or understate the business. Both sit under the wider self-employed home loan umbrella, and the Business Owners Hub links the rest of the lane.
What documents does a sole trader need for a home loan?
A sole trader needs proof the business is active, proof of the income it produces, and the standard personal documents every borrower provides. The table below is the sole trader file checklist, split by what a full doc lender and a low doc lender typically ask for. Exact lists vary by lender.
| Document | Full doc lender | Low doc lender |
|---|---|---|
| ABN | Required, active, with a minimum trading history that varies by lender | Required, active; some lenders accept a shorter history |
| GST registration | Not required; checked against your turnover | Often expected where BAS is the income evidence |
| Personal tax returns | Two lodged returns, typically | Not always required; may be replaced by other evidence |
| Notices of assessment | Required to match each return | Asked for where a return is used |
| BAS | Sometimes asked for to show current trading | Often the main income evidence, recent quarters |
| Bank statements | Personal statements for savings and conduct | Business and personal statements, often a longer run |
| Accountant letter | Rarely needed | Accepted by some lenders in place of returns |
On top of the income documents, every file carries photo ID, evidence of your deposit and a full list of your debts and limits. In our own files, the documents that hold things up are rarely the hard ones. It is usually a missing notice of assessment or a quarter of BAS that was lodged late.
If you want to see how the full doc list grows for different structures, the full doc documents for self-employed borrowers insight walks through it. For the low doc side, what lenders look for in business bank statements explains what a statement-based file has to show.
How do lenders work out sole trader income from your tax return?
Lenders work out sole trader income from the net business income on your personal tax return, then adjust it for a short list of items that reduce tax without reducing cash. They are not reading your turnover. A business that turns over a large amount but shows a small profit is assessed on the profit.
The lender takes the business income line from the return, checks it against the BAS and bank statements for consistency, and confirms the return was processed by the ATO. The notice of assessment proves it was lodged. A return with no matching notice is usually treated as a draft, however accurate it is.
Which add backs can lenders put back into sole trader income?
Some lenders add back expenses that lowered your taxable profit but did not cost you cash in that year, such as depreciation, and sometimes interest on a business loan that is being refinanced or paid out. One-off costs can also be considered with evidence. Which add backs are accepted varies by lender, and the detail is covered in the sole trader business loans insight, because the same logic applies to business lending.

What happens if your income went up or down between years?
If your income moved between years, the lender decides which year to rely on, and the lower year often wins. A full doc lender reading two returns will typically average them when income is rising, and use the lower figure when income has dropped.
- Income rising. Many lenders average the two years. Some will use the latest year alone when the rise is well explained and supported by current BAS.
- Income falling. Most lenders use the lower, more recent year, and may ask why it fell and whether it has recovered.
- One unusual year. A large one-off job or a slow year from illness or a move can be explained, but the explanation needs evidence, not just a note.
What if your latest year is much stronger than the one before?
If your latest year is much stronger, the right lender matters more than anything else. In deals I've seen, the same two returns can produce quite different income figures depending on whether the lender averages or takes the latest year. That gap is often the difference between the loan working and not.
How long does your ABN need to be active, and does GST registration matter?
Most full doc lenders want your ABN active for around two years, though some accept 18 months to 2 years depending on your industry history, and some low doc lenders accept less. ABN age is a proxy for stability: the lender wants to see the business has been through at least one full tax year and kept going.
Time in the same line of work before you went out on your own can help. A lender may weigh a newer ABN more kindly if you did the same job as an employee beforehand. Policy on this varies by lender.
Does GST registration help a sole trader's application?
GST registration helps mostly because it gives you BAS, and BAS gives a lender a recent, ATO-lodged view of your turnover. GST registration is not a lending requirement, and plenty of smaller sole traders are not registered. Without it, expect a low doc lender to rely more heavily on business bank statements.
What if you have only lodged one tax return as a sole trader?
If you have only lodged one tax return as a sole trader, you are not locked out; some lenders will assess a single strong year, and low doc and one doc paths can fill the gap. The trade-off is usually a lower maximum LVR or a higher price than a two-return full doc file.
Two posts cover this in depth. Using one strong tax year explains how a single return is read, and ABN age milestones sets out what changes as your ABN gets older. If you are buying your first place on a young ABN, the self-employed first home insight is the closer fit.
If most of your income comes from one client on a contract, the assessment can follow different rules, and the contractor and PSI home loans insight covers that case.
Does being a sole trader rather than a company owner change the assessment?
Being a sole trader rather than a company owner changes the assessment in two ways: all the income is on one personal return, and every business debt is yours personally. A sole trader has no separate entity between them and the business, which business.gov.au sets out plainly.
The first part makes the income simpler to read. There are no company financials, no wages from a company to reconcile and no retained profits to argue about. The second part cuts the other way. A sole trader's business debt is personal debt, so a business loan, an overdraft or a car on finance through the business is counted in full against your home loan, with no guarantee question to work through. Your credit file also carries the business accounts, which small business credit reports explains by structure.
Whether you should stay a sole trader or move to a company is a tax and structure question, not a home loan one. If you already run a company, the company director mortgage options insight covers how your income is read instead.
Why do sole traders get declined for home loans, and what can you fix first?
Sole traders usually get declined because of the file, not the business: late returns, income on paper lower than the real business, mixed personal and business accounts, or debts that were not disclosed. Most of these can be fixed, which is why the rule is fix the file before the application. A declined application leaves an enquiry on your credit file, so the second attempt starts from a weaker place.
A file that moves
- Returns lodged and assessed
- BAS current, matching the bank deposits
- Business and personal accounts kept apart
- Every debt and limit listed upfront
A file that stalls
- Latest return still with the accountant
- Income figure well below what the business earns
- Personal spending through the business account
- A business card or car loan left off the list
- Lodge what is outstanding. Get any late returns lodged and wait for the notices of assessment.
- Check the income figure. Ask your accountant which add backs apply, so you know the number a lender is likely to use.
- Tidy the accounts. Run business income and spending through one account for the months before you apply.
- List every debt. Include business limits, cards and finance in your own name.
- Pick the path. Decide between full doc and low doc before you choose a lender, not after a decline.
The self-employed home loan declined guide covers each decline reason in detail. If an accountant letter was part of the problem, why accountant letters get rejected shows what lenders need it to say.
A sole trader's home loan rests on one personal tax return line: the net business income. Full doc lenders want that line proven by lodged returns and notices of assessment, usually two years of them, and they will often take the lower year when income moves. Low doc lenders work from BAS, statements or an accountant letter instead, at a different price and LVR. Every business debt counts in full because it is yours personally. When returns are behind or understate the business, a one doc home loan can carry the file on a single income document.
Key takeaway: lodge, tidy and list everything before you apply, then choose the full doc or low doc path that fits the documents you actually have.Frequently Asked Questions
How much a sole trader can borrow depends on the income the lender accepts, not the turnover: usually the net business income on your return, plus the add backs that lender allows, less your existing commitments, tested at a buffered rate. Low doc lenders start from the income you declare and check it against BAS or bank statements, often at a lower maximum LVR. A broker can run the same figures through several lenders' rules before you apply.
You can get a home loan with a one year ABN with some lenders, especially if you worked in the same industry before you started trading. Some will assess a single lodged return, and low doc or one doc lenders may work from BAS or an accountant letter instead, usually at a lower maximum LVR or a higher price. A one doc home loan suits files where one strong document tells the story.
Getting a home loan as a sole trader is not hard when the file is complete, but it is harder than it needs to be when returns are late or the income figure on paper is lower than the real business. Most declines trace back to timing and paperwork rather than the business itself. Lodging returns, keeping business and personal accounts apart and knowing which year the lender will read all make a large difference. The self-employed decline guide covers the common reasons in detail.
You do not need to be registered for GST to get a home loan as a sole trader, because GST registration depends on your turnover and is not a lending rule in itself. It matters more on low doc loans, where many lenders use your BAS to verify the income you declare, and you only lodge BAS if you are registered. Without GST registration, a lender will usually lean on your tax returns or business bank statements instead.
A sole trader can often use BAS instead of tax returns for a home loan, but only with a low doc or alt doc lender, not a full doc one. The lender reads the turnover in your recent BAS, often alongside business bank statements or an accountant letter, and works out a conservative income from it. Expect a lower maximum LVR and a higher price than full doc. The BAS home loan insight explains how lenders read the statements.
