Home Loans for Sole Traders in Perth, WA, Self-Employed Lending Explained
Running your own business means your income looks different on paper, and lenders know it. If you've been lodging tax returns showing modest drawings while reinvesting the rest, or if your first year's profit was low and your second strong, you're not a bad borrower. You're just one a bank's standard form wasn't built for.
Sole traders in Perth, WA can absolutely get a home loan, and many do. What changes is which lender you choose, how your financials are presented, and whether your broker knows which policies apply to your structure. A registered ABN, two years of trading history and a decent deposit puts most sole traders in a workable position. The question is which lender on a wide panel reads your numbers most favourably.
At Launch Finance, we help sole traders and self-employed buyers across Perth compare options across 60+ lenders. The self-employed home loan side of it is where lender choice makes the biggest difference, because the gap between the most and least generous assessments of the same income can be substantial.
Key takeaways
- Two years of tax returns is standard; some lenders accept one.
- Lenders add back depreciation and some expenses to lift your assessed income.
- Low doc options exist at lower LVRs where returns aren't available yet.
Can sole traders in Perth, WA get a home loan on their business income?
Yes, sole traders can get a home loan using business income, and the same serviceability rules apply as for any other borrower. What differs is the evidence required. Lenders want to see that your income is real, consistent and sustainable, and for a sole trader that means tax returns rather than payslips. Most lenders want two full years of returns, and they'll use your net profit, not your turnover, as the starting figure. REIWA data shows Perth house medians ranging from $700,000 in Armadale to over $2.3 million in Subiaco, so the loan size you're targeting will shape which lenders and which structures suit you best.
How do lenders assess a sole trader's income?
Your net profit after tax is the base, but it's rarely the number lenders use without adjustment. Most lenders apply a process called add-backs, where legitimate business expenses that reduced your taxable profit are added back to produce a higher assessable income. The most common add-backs are depreciation, one-off capital costs, and certain personal expenses run through the business. Whether a lender accepts a given add-back, and how much weight they give it, varies.
Whether you've been a sole trader for one year or ten also matters. Two years of returns is the standard requirement at most mainstream lenders, and they'll average the two years' net profit if income has fluctuated. Where the second year is meaningfully higher than the first, some lenders will use the most recent year only, which lifts your assessed income and your borrowing capacity.
GST registration and a minimum ABN tenure also come into the picture. Most lenders want to see that the ABN has been active for at least one to two years before they'll assess the income as stable. A sole trader who incorporated or changed structures recently may find fewer lenders willing to look at the full income picture.
A lot of sole traders come in thinking their income is the problem, when the real issue is how it's been presented. The tax return might show $65,000 net profit, but once we've worked through depreciation and legitimate add-backs with the right lender, we're looking at a genuinely different assessment figure.

What eligibility criteria apply to sole traders?
Lenders verify several things beyond income before they'll approve a self-employed application. Meeting these requirements is usually a matter of preparation rather than eligibility.
What lenders typically want to see:
- › ABN registration: an active ABN, usually for a minimum of one to two years before application.
- › Tax returns: two years of personal tax returns and accompanying notices of assessment, lodged and up to date with the ATO.
- › BAS statements: business activity statements for the past four to eight quarters, confirming ongoing trading activity.
- › Business bank statements: typically the last three to six months, showing consistent cash flow that supports the income declared.
- › Accountant's letter: some lenders, and most low doc products, require a letter from a registered accountant confirming the business is active and the income figure stated.
- › Credit position: standard credit checks apply, including any existing business liabilities, which are assessed as ongoing commitments against serviceability.
How much can a sole trader borrow in Perth?
Borrowing capacity for sole traders follows the same serviceability mechanics as for any employed borrower. The APRA serviceability buffer applies at 3.0 percentage points above your actual loan rate, so you're assessed at a meaningfully higher rate than the one you'll pay. What differs for sole traders is the income figure that goes into that calculation, and that's where lender choice moves the number the most.
The add-back process, the number of years averaged, and whether a lender accepts a single recent year can shift your assessed income by tens of thousands. At a typical LVR, that difference flows directly into your maximum loan size. The APRA DTI cap also applies at mainstream lenders, limiting how much high-debt-to-income lending a bank can write, and sole traders on variable income sometimes sit at higher DTI ratios than equivalent salaried borrowers.
REIWA data shows Perth house medians from $700,000 in Armadale and $710,000 in Midland through to over $2.2 million in Rossmoyne and beyond. Suburbs like Ellenbrook, Maddington or Cannington sit under or around the $850,000 Perth price cap for federal schemes, which matters for first-home sole traders in particular.

What government schemes can sole traders use?
Being self-employed doesn't exclude you from any of the major federal or WA schemes. Eligibility runs on your income, your deposit and the property price, not on your employment type.
The schemes worth knowing about:
- › First Home Guarantee: 5% deposit, no LMI, no income test. Perth price cap $850,000. First home buyers only.
- › WA First Home Owner Grant:$10,000 for new homes only, capped at $800,000 south of the 26th parallel. Not means-tested, but the property must be new or substantially renovated.
- › WA first home owner duty concession: nil duty on homes up to $600,000, concessional rate to $800,000. Applies to new and established homes for first buyers.
- › Help to Buy: federal shared equity, up to 30% for existing homes and 40% for new builds. Income cap $103,000 single or $165,000 joint from 1 July 2026. Perth price cap $850,000. Cannot be combined with Keystart shared equity.
- › Keystart Low Deposit Home Loan: from a 2% deposit, no LMI. Income limits $155,000 singles, $228,000 couples and families. Property limit $860,000 across WA.

The schemes themselves don't assess income any differently for sole traders. The lending product underneath them does, which is why getting the application structure right matters as much as scheme eligibility.

How do mortgage brokers improve outcomes for sole traders in Perth, WA?
The lender choice decides the outcome here, not the rate alone. Three policy differences move the number for sole traders, and they're not published side by side anywhere.
- › Add-backs: which lenders include depreciation and one-off expenses when calculating your assessable income, and which only take the net profit figure from the return.
- › One-year assessment: whether a lender will use your most recent year's income where it's meaningfully higher than the year before, rather than averaging the two.
- › Accountant's letter in lieu of a second return: some lenders accept a letter from your registered accountant confirming current income where a second full year of returns isn't yet available.
Comparing across a wide panel finds which combination of these policies gives your application the strongest footing before a single lender sees it.
When does a full-doc loan not make sense for a sole trader?
If your tax returns are up to date, your income is consistent, and your ABN has been active for two or more years, a full-doc loan is almost always the right path. The rate is lower, the LVR can go higher, and the lender pool is wider.
A low doc loan becomes worth considering where your returns aren't yet filed for the second year, where your income structure is genuinely difficult to document under a standard assessment, or where you've recently changed business structures. Low doc products typically require a larger deposit and carry a rate premium over full-doc equivalents. For most sole traders with a clean file and current returns, the documents are the better option even where they're inconvenient to pull together.
The situation where it genuinely doesn't work is when taxable income has been deliberately minimised over both years. A lender assesses what the tax return shows, and if that figure won't service the loan even with add-backs, the conversation is usually better delayed until the next return better reflects what the business actually earns. Applying early and being declined costs you a credit enquiry and doesn't change the underlying picture.
Where a client's returns have been structured to minimise tax, the honest conversation is usually about timing. Getting the next return lodged first, then applying, is nearly always the cleaner path than trying to work around what the paperwork shows.

What approval challenges do sole traders face?
Where applications lose ground:
- › Returns not yet lodged: a lender can only assess what's on file with the ATO. If your most recent return is overdue, getting it lodged before applying opens up the full lender pool and often the better income figure.
- › Income declining between years: where year two is lower than year one, most lenders average the two and some will use the lower. This is the reverse of the one-year-assessment advantage, and it's worth knowing before you apply.
- › Business liabilities on the personal file: sole traders often carry equipment finance, a business overdraft or a credit card in their own name. Each one is assessed as a personal commitment and reduces borrowing capacity, even where the business services it entirely.
- › GST registration gap: some lenders require GST registration for a minimum period, not just ABN registration. A sole trader below the GST threshold who's never registered can find the lender pool narrower than expected.
- › Applying to the wrong lender first: a decline at one lender leaves an enquiry on the credit file. Identifying which lenders' policies suit your income structure before any application goes in is where a broker does the most useful work.
Frequently Asked Questions
Do sole traders need a bigger deposit than employed borrowers?
Not necessarily. Sole traders can borrow to the same LVRs as employed borrowers with the right lender. A larger deposit does widen the lender pool and reduces the scrutiny on income documentation, but it isn't a requirement across the board.
Can I use one year of tax returns instead of two?
Some lenders accept one year, usually paired with an accountant's letter confirming the business is active and the income sustainable. The pool of lenders willing to do this is narrower, and the rate may reflect that, but it's a genuine option where the second return isn't yet available.
Do add-backs apply to every sole trader application?
Add-backs depend on which lender assesses your application. Not every lender applies them, and the items they'll accept vary. Depreciation is the most commonly accepted; one-off personal expenses run through the business are more contested. Whether the right lender for your situation offers add-backs depends on which lenders your broker has access to and your specific financials.
How does a low doc loan differ from a standard sole trader loan?
A low doc loan substitutes the accountant's letter and BAS for tax returns. It typically comes with a lower maximum LVR and a rate premium over a full-doc loan. It suits sole traders who can't yet produce two years of returns, not those who simply prefer not to.
Can I use the First Home Guarantee as a sole trader?
Yes. The First Home Guarantee has no income test and is available to first home buyers regardless of employment type. The $850,000 Perth price cap and the 5% deposit requirement apply in the same way as for any other buyer.
Should I use a mortgage broker or go directly to my bank?
A mortgage broker, every time. Self-employed income assessment varies significantly between lenders, and your own bank has one policy. A broker compares that policy against a wider panel and finds the lender whose add-back rules and income-averaging approach give your application the strongest position.
Your Next Steps
For sole traders, the home loan outcome is determined before the application goes anywhere near a lender. The income figure, the add-backs, the document structure and the lender selection all happen in the preparation stage, and getting those right is what separates an approval from a decline or a weaker offer than you deserved.
The right lender for your situation depends on your income structure, and that's a conversation worth having before you apply. Talk to the Launch Finance team or call 08 9367 4222, and we'll compare your options across 60+ lenders.
