Australian self-employed borrowers face a distinct hurdle in 2025 that has little to do with their actual cash position and everything to do with how lenders read a tax return. The minimum net profit figure that opens the door to a home loan is not a single number — it is a moving target set by a patchwork of lender policies, the remaining effects of APRA’s buffer regime, and a rate cycle that has pushed serviceability calculators to their limits. As the official cash rate sits at 4.35 per cent and non-bank funders tighten their alt-doc nets, the question of “how much profit is enough” has become the decisive filter between approval and decline.
For a company director who draws a low salary but retains earnings inside the business, or a sole trader who applies every available deduction, the assessable net profit — as defined by an individual lender’s add-back policy — can easily fall $15,000 to $40,000 short of what a mainstream bank demands. In the low-doc and alt-doc space, where applicants verify income via BAS statements, accountant letters, or business activity declarations, the minimum profit threshold is not just a number; it is the difference between accessing a 70 per cent loan-to-value ratio (LVR) on a $1.2 million purchase and being knocked back entirely. This piece maps the actual profit benchmarks now in force across Australia’s primary specialist lenders, explains how buffers and debt-to-income (DTI) caps interact, and identifies where the policy margins lie for a self-employed borrower trying to turn business revenue into residential lending capacity.
How Lenders Assess Self-Employed Income
Lenders do not see profit the way a tax accountant does. They begin with the net profit before tax from the most recent two years’ financial statements — usually the figure on the tax return — then adjust it. The adjustments, or add-backs, are where capacity can swing materially. A borrower with $62,000 of tax profit might, after add-backs, show $95,000 of assessable income for a particular non-bank. Another lender using a different add-back matrix might allow only $72,000. The gap changes everything: it can add $150,000 to a borrowing power calculation.
The Net Profit Before Tax Benchmark
For low-doc and alt-doc submissions, the baseline remains net profit before tax averaged over the most recent two financial years, provided the latest year is not lower. If 2023–24 shows $58,000 and 2022–23 showed $63,000, most lenders will take the lower of the two, or an average of $60,500, depending on their policy. Pepper Money, for instance, will use 100 per cent of the most recent year’s net profit if it is supported by an accountant’s letter confirming ongoing viability. Liberty Financial’s low-doc option for self-employed borrowers with perfect credit takes the latest year at face value on a Prime Full Doc Lite product, but where a BAS-only pathway is used, it defaults to the most recent 12 months of BAS figures grossed up by a factor of 0.50 to 0.60. Brighten Home Loans, under its Easy Doc suite, assesses a single year of tax returns and business activity statements if the ABN has been registered for more than two years, with a minimum net profit of $30,000 required.
Add-Backs That Move the Dial
Add-backs are policy-specific. La Trobe Financial’s low-doc products, including the Super Doc and Lite Doc lines, allow depreciation, interest on business loans, non-cash expenses, and voluntary super contributions to be added back to the net profit before calculating serviceability. Bluestone Mortgages, on its full-doc and alt-doc tiers, permits add-backs for interest, depreciation, one-off expenses, and director’s fees if they are not drawn as cash. The effect can lift assessable income by 20 to 40 per cent. A borrower with a $70,000 net profit from a trading entity, after adding back $15,000 of depreciation and $7,500 of interest, might present $92,500 — crossing the threshold where a $600,000 loan becomes possible at a 6.5-times DTI cap.
Not all add-backs are automatic. Lenders require evidence: a depreciation schedule, loan statements, or an accountant’s verification letter. Where a BAS-only or accountant-letter pathway is used, add-backs are rarely allowed because there is no full financial decomposition. This is the key trade-off: simpler verification means less room to inflate the profit number.
Minimum Net Profit Thresholds by Lender Category
No single number defines “minimum net profit” across the market. The figure depends on whether the applicant is using full-doc, alt-doc, low-doc, or a BAS-only approach, and which lender’s credit appetite applies. Broadly, the market segments into three tiers.
Specialist Non-Bank Lenders
Pepper Money’s Near Prime and Specialist low-doc options require a minimum annual income of $30,000 from self-employment, which can be evidenced with six months of business bank statements showing consistent revenue, an accountant’s letter, and a declaration of financial position. Liberty Financial’s Super Credit low-doc demands a minimum net profit of $35,000 if using an accountant’s letter, rising to $45,000 where only BAS statements are supplied. Resimac’s Prime and Specialist alt-doc loans set the floor at $40,000 of declared income from the business, with the most recent year’s tax return accepted provided the business has been trading for a minimum of two years. Bluestone’s Crystal Clear low-doc does not publish a rigid minimum but internal credit guidelines indicate $45,000 is the usual threshold below which an asset-lend or equity-release structure becomes the alternative.
La Trobe Financial adopts a different calibration. Its Lite Doc product, which requires only an accountant’s declaration and 12 months of BAS, sets a minimum net profit of $50,000 for metropolitan postcodes and $40,000 for regional areas. This split reflects La Trobe’s risk-weighting of location and the lower property liquidity outside capital cities.
Prime Alt-Doc Options
Brighten’s Easy Doc Alt Doc line, aimed at near-prime borrowers with clean credit, sets a minimum net profit of $30,000 where the applicant provides one year’s tax return and notice of assessment, and the LVR does not exceed 70 per cent. If the LVR moves above 70 per cent, Brighten’s minimum required income rises to $50,000. A similar LVR-linked income floor operates inside select credit unions. For example, Police Bank’s alt-doc product for self-employed members (available through brokers) requires a minimum of $40,000 assessable income when the LVR is 80 per cent, dropping to no explicit minimum at 60 per cent LVR where the loan falls under its asset-based lending policy.
BAS-Only and Accountant Letter Pathways
When the applicant cannot produce full financials, the minimum profit requirement often climbs because the lender builds in an income haircut. BAS-only calculations typically take the total sales from the last 12 months of BAS statements, apply a fixed industry margin (for example, 20 per cent for a professional services firm), and then apply a further 80 per cent conversion to arrive at an annual income figure. If a sole trader declares $200,000 in total sales, a 20 per cent margin yields $40,000, and the 80 per cent haircut leaves $32,000 — enough for some lenders, but not for La Trobe’s Lite Doc metro floor. Accountant-letter pathways, where the accountant attests to the applicant’s income based on management accounts, generally command a minimum of $45,000 to $60,000, depending on the lender and the LVR. Resimac’s Accountant’s Letter Variation, for example, accepts a letter with a figure no lower than $45,000, provided the letter confirms the income is sustainable and the applicant has been trading for two years.
Serviceability Buffers and Net Profit Calculations
Even when the declared net profit clears the lender’s minimum, the real test is whether that profit generates enough borrowing capacity after the serviceability buffer and DTI cap are applied.
The 3% Buffer and Your Bottom Line
APRA’s July 2024 decision to remove the 3 per cent serviceability buffer for standard residential lending (APRA letter to ADIs, 6 July 2024) did not fully erase the buffer for non-bank and low-doc originators. Many specialist lenders, including Pepper, La Trobe, and Resimac, retained an internal assessment rate of at least 2.5 per cent above the product rate or the floor rate, whichever is higher. For a low-doc loan priced at 8.39 per cent, the assessment rate can be 10.89 per cent. A net profit of $70,000, after deducting estimated living expenses of $24,000 (the Household Expenditure Measure for a single borrower), leaves $46,000 a year to service debt. At a 10.89 per cent assessment rate over a 30-year term, that profit supports roughly $425,000 of borrowing, not the $600,000 a casual glance at the DTI cap might suggest. This is the pinch point: the buffer eats into the capacity before the DTI limit bites.
Liberty Financial applies a variable buffer depending on credit score and product tier. On its Prime Full Doc Lite for self-employed, the assessment rate is typically 1.50 per cent above the product rate for LVRs up to 70 per cent, rising to 2.00 per cent for higher LVRs. This makes Liberty one of the more generous calculators for a borrower who can meet the full-documentation standard.
DTI Caps That Constrain Borrowing
Debt-to-income ratios now operate as a hard ceiling at most lenders. Pepper Money’s low-doc products impose a maximum DTI of 9 times, as outlined in its September 2024 product guide, meaning a $70,000 net profit will not support a total debt beyond $630,000. La Trobe Financial applies a more conservative 7-times cap on its Lite Doc line for LVRs above 60 per cent, softening to 8-times at 60 per cent LVR or below. Bluestone’s alt-doc DTI limit sits at 6.5-times for borrowers with a credit score below 600, and 8-times for scores above that. Brighten’s alt-doc DTI cap is 8-times across the board, but where the LVR exceeds 80 per cent, the cap drops to 7-times. The practical result: a borrower earning $55,000 net profit who seeks an 85 per cent LVR under Brighten’s policy will hit the 7-times DTI cap at $385,000 total debt, which may not be enough to fund the purchase after allowing for existing liabilities.
The Interaction of LVR and Net Profit
Equity changes the profit conversation entirely. At lower LVRs, lenders shift their focus from income verification to asset security, and the minimum net profit requirement either drops or disappears.
How Equity Softens the Profit Requirement
At 60 per cent LVR or below, most specialist lenders offer some form of asset-lend or equity-release product where income is not verified beyond a declaration that the borrower can afford the repayments. La Trobe’s Super Doc, for LVRs up to 60 per cent, does not require a minimum net profit figure — the loan is assessed on the value of the security property and an exit strategy. Pepper Money’s Asset Lend operates similarly, with no minimum income requirement provided the applicant has a clear credit history and the loan purpose is acceptable. This is the pathway for a self-employed borrower with a property worth $1.5 million and seeking a $900,000 loan: zero assessed net profit is required, as long as the equity buffer is there. Liberty Financial’s Super Equity product works on the same principle for LVRs up to 55 per cent, focusing on net asset position rather than taxable income.
When a 60% LVR Opens Doors
Even where a full asset-lend product is not used, a 60 per cent LVR often triggers a lower income floor. Resimac’s alt-doc offering reduces the minimum net profit to $30,000 when the LVR is 60 per cent or less, compared with $45,000 at higher LVRs. Brighten’s Easy Doc floor drops to zero for LVRs at or below 60 per cent, provided the loan is not for business purposes and the borrower can demonstrate a clear saving history. This makes a well-timed refinance or a larger deposit a powerful lever for a self-employed applicant whose tax returns show a profit below the usual $45,000 marker. A borrower with $30,000 of net profit who can put down a 40 per cent deposit on an $800,000 property may find the door open at a lender that would otherwise decline the same application at 80 per cent LVR.
Closing: Five Actionable Takeaways
- Know your starting number. Obtain your latest two years’ tax returns and note the net profit before tax line. If the most recent year is lower than the previous, your assessable income for many lenders will be that lower figure — unless you add back qualifying items. Map out all available add-backs (depreciation, interest, one-off expenses) and have your accountant document them.
- Match the verification pathway to your profit. If your net profit sits between $30,000 and $45,000, avoid BAS-only products; use a full-doc or accountant-letter pathway with a lender like Liberty or Resimac that accepts a single year’s return and allows add-backs. If your profit is above $45,000 but below $60,000, Brighten or Pepper’s alt-doc may work, but check the LVR-DTI interaction first.
- Calculate serviceability before applying. Using an assessment rate of at least 2.5 per cent above the product rate, work out how much debt your profit supports after living expenses. Compare that figure with the lender’s DTI cap. The smaller number is your actual borrowing ceiling. If the gap between the profit-supported amount and the required loan is narrow, reduce the LVR or pay down existing debt.
- Use equity as an income substitute. At 60 per cent LVR or below, income verification becomes a secondary concern. If you hold sufficient equity but lack taxable profit, target La Trobe’s Super Doc, Pepper’s Asset Lend, or Liberty’s Super Equity before abandoning the application.
- Engage a broker who can price across the non-bank panel. The difference between a La Trobe Lite Doc at 7-times DTI and a Liberty Prime Full Doc Lite at a 1.50 per cent buffer can translate to an extra $120,000 of borrowing capacity on the same declared net profit. An experienced low-doc broker will run parallel scenarios and identify the intersection of LVR, DTI cap, and buffer that makes the application viable.
