The Reserve Bank of Australia has held the cash rate at 4.35 per cent since November 2023, and APRA removed its standardised 3‑percentage‑point serviceability buffer on 25 June 2024, returning assessment floor discretion to lenders. In the same window, Australian Business Register data shows more than 2.5 million active ABNs, with sole traders the fastest‑growing cohort. For a sole trader who registered an ABN less than 24 months ago, the intersection of these forces is sharp: while a handful of specialist lenders now accept six‑month business activity statements or an accountant‑declared income figure, credit teams are mapping short trading histories against higher default probability, lower LVR ceilings and punitive risk margins.
Major banks typically enforce a 24‑month ABN and tax‑return rule, a practice that shut out early‑stage sole traders throughout the rate‑tightening cycle. Non‑bank lenders — Pepper Money, La Trobe Financial, Liberty, Resimac, Bluestone and Brighten — have stepped into the vacuum, but their policy manuals are granular. A sole trader who crossed $75,000 in GST turnover may be able to borrow up to 80 per cent of a property’s value under a full‑alt‑doc pathway; a sub‑$75,000 trader might be capped at 70 per cent LVR and face a rate premium of 80 to 120 basis points above a standard variable rate. The deal is workable, but it demands a document set that proves income consistency before the application lands in a credit analyst’s queue.
These dynamics make the sub‑two‑year ABN mortgage a live negotiation, not a product‑off‑the‑shelf, and the outcomes are dictated as much by the nature of the income stream as by the calendar age of the ABN.
The two‑year rule — myth, origin and where it still applies
What the NCCP Act says (and doesn’t say)
The National Consumer Credit Protection Act 2009 and its responsible‑lending obligations do not prescribe a minimum ABN age. ASIC’s Regulatory Guide 209 makes clear that a licensee must take reasonable steps to verify a borrower’s financial situation, but the form of verification is left open. The 24‑month convention originated in lender risk appetite, not statute. After the banking royal commission, major banks codified the two‑year tax‑return requirement as a safe‑harbour threshold, and it hardened into an industry norm.
Major banks and the 24‑month ABN policy wall
The big four, along with most mutuals, will not entertain a sole trader application without two full years of lodged tax returns and corresponding ATO notices of assessment. CBA, NAB, Westpac and ANZ all reference the 24‑month test in their self‑employed credit guides as at October 2024. Even where a borrower has a 12‑month ABN and a single tax return, frontline assessors are instructed to decline unless a clear exception exists — for example, a contractor moving from a PAYG role into an ABN structure with an identical industry, where prior PAYG income can be blended. That exception is narrow and rarely granted.
When a shorter ABN history can work via alt‑doc
Alt‑doc lending is the primary bypass. In this market, a lender accepts non‑traditional income verification: BAS statements, business bank account transaction histories, accountant‑prepared profit‑and‑loss declarations, or a combination. The key is that the lender is willing to accept an ABN registration date of six months or more instead of two years. Nearly all alt‑doc lenders — the ones mentioned above — floor the ABN requirement at six months, though a few will consider three months on an exception basis with additional deposit strength.
How specialist lenders assess ABNs under two years
BAS‑only pathways
Pepper Money’s Near Prime Self‑Employed product allows a six‑month ABN with lodging of two quarterly BAS statements (or six months of monthly IAS). Liberty Financial’s Freedom Low‑Doc range similarly asks for six months of BAS or an accountant‑certified income statement for an ABN aged six months. In both cases, the income used for serviceability is the annualised gross business income shown in the BAS, less a default expense ratio — usually 20 per cent for a service‑based sole trader and up to 50 per cent for a trade business with high costs of goods sold. No tax returns are required, and the ATO portal will be checked to confirm the BAS were lodged.
Accountant letter loans and early‑stage income testing
When BAS figures are lumpy or the sole trader has been operating for only a single quarter, an accountant‑certified declaration is the alternative. La Trobe Financial’s Specialist Alt‑Doc product and Resimac’s Alt‑Doc offering both accept an accountant’s letter that states a corroborated net profit before tax for the most recent trading period, provided the period is at least six months. The accountant must be registered and the letter must show a derived annualised income figure. Lenders will apply a haircut — 10 to 15 per cent — to that figure to account for early‑stage volatility.
LVR and rate differentials for sub‑24‑month files
Pricing and maximal leverage are tied directly to the length of the ABN and the quality of the document set:
- ABN 6‑11 months + BAS only: maximum LVR 70 per cent. Rates from 7.14 per cent p.a. (comparison 7.48 per cent p.a.). A risk fee of 1.5 per cent of the loan amount is common.
- ABN 12‑23 months + BAS or accountant letter: LVR up to 80 per cent. Rates from 6.99 per cent p.a. (comparison 7.33 per cent p.a.). Risk fee drops to 0.75–1.0 per cent.
- ABN 24+ months but no tax returns: LVR may reach 85 per cent at prime‑adjacent pricing, e.g. 6.79 per cent p.a.
These figures are based on indicative rate sheets from specialist non‑bank lenders as at October 2024 and assume a loan amount above $150,000 with principal‑and‑interest repayments on an owner‑occupied security.
Serviceability and buffer arithmetic for a fledgling sole trader
Applying the post‑APRA buffer landscape
Since APRA’s June 2024 decision, lenders may set their own residential mortgage serviceability floors. Most non‑bank alt‑doc lenders have adopted a buffer of 1.0 to 2.5 percentage points above the loan’s actual rate. Brighten’s Alt‑Doc product, for instance, applies a 2.0‑per‑cent buffer; Bluestone’s Lite Doc range uses a flat 1.5‑per‑cent buffer. This is significantly more generous than the old 3‑per‑cent mandate, improving borrowing power by as much as 15 to 20 per cent for the same gross income.
Real‑world example: $120,000 declared net profit, DTI limits
Consider a sole trader with a $120,000 annual net profit stated on an accountant’s letter, operating 10 months under an ABN. After a 15‑per‑cent haircut, the lender assesses $102,000. Adding a 2‑per‑cent buffer to a product rate of 6.99 per cent, the qualifying rate is 8.99 per cent. With a loan term of 30 years, that borrower might qualify for a maximum loan size around $480,000 under most commonly used calculators, assuming no other liabilities and standard living expenses. The DTI cap enforced by many alt‑doc lenders — often 6.0 times gross income — limits the borrowing ceiling further: 6 × $102,000 = $612,000, but serviceability usually bites before DTI.
Living expenses: the HEM‑plus‑adder effect
Low‑doc applications are scrutinised for declared living expenses. If the borrower’s business bank account shows personal drawings, lenders will cross‑reference the sole trader’s stated household spending with the Household Expenditure Measure benchmark. Where a six‑month bank statement shows an average monthly personal expenditure higher than the HEM figure, the higher number will be used. This can shrink borrowing power by tens of thousands of dollars if not pre‑analysed.
Risk pricing and the documents that move the needle
The six‑month BAS pack — what gets accepted
A compliant BAS‑only submission typically requires: GST‑registered ABN (or evidence of voluntary registration if turnover is under $75,000); the two most recent quarterly BAS lodged via the ATO business portal; and ATO integrated client account transcripts showing those lodgements. Lenders will annualise total sales (G1) and compare the income trend — a rising quarterly pattern adds weight, a flat or declining one invites an expense‑ratio override.
Bank statements as alternative income evidence
Resimac and Bluestone accept six months of business transaction account statements as the primary or supplementary income document for some alt‑doc offerings. The loan assessor will isolate inflows that have the characteristics of trading revenue — regular client payments, contract proceeds, sale of stock — and exclude lumpy non‑recurring transfers. The average monthly trading income is then annualised, with a scaled expense deduction based on ANZSIC industry benchmarks. This pathway benefits sole traders with irregular BAS lodgements but a clean, steady bank record.
GST registration and ATO portal verification
Where the sole trader is GST‑registered, the lender will verify registration status via the ABN Lookup and ATO portal. If the trader is below the $75,000 registration threshold and chooses not to register, the lender will typically treat the income as GST‑exclusive and may apply a higher expense ratio (often 30 per cent rather than 20 per cent) because of the assumed absence of systematic record‑keeping. Voluntary GST registration is a clear signalling mechanism to a credit assessor.
Steps to take before applying with a sub‑two‑year ABN
Clean business account separation
A sole trader who operates out of a single mixed‑use account is more likely to be declined or receive a lower LVR offer. Separating business and personal banking at least three months before application allows the lender to isolate trading income and GST components without the noise of grocery transactions. It also makes the BAS pack cleaner and reduces expense‑ratio disputes.
Lodging BAS on time and showing consistency
Every late‑lodged BAS creates a data gap that alt‑doc lenders treat as a negative indicator. Lodging quarterly BAS by the due date — typically 28 days after quarter‑end — and ensuring the ATO integrated client account shows zero outstanding debt at the time of application improves the file rating. Consistency in quarterly sales (within a 10 to 15 per cent band) is valued higher than a spike‑and‑trough pattern.
Pre‑assessment through a specialist broker
Given the policy variation across Pepper, Liberty, La Trobe, Resimac, Bluestone and Brighten — and the frequent pricing adjustments — a credit‑savvy broker who maintains live product matrices will identify the lowest‑cost lender that can accept the specific ABN age, document mix and LVR requirement. A pre‑assessment that includes a full living‑expense review and a desktop valuation of the security before a full application is filed reduces the risk of a credit‑file‑damaging decline.
Three moves to make before lodging a loan application
A sole trader with an ABN of less than two years should focus on actions that directly shift the pricing and LVR outcome. First, segment the business bank account at least 90 days ahead of the application; a dedicated trading account with six months of clean history lifts the document credibility across all alt‑doc programmes. Second, lodge every BAS on time and clear any ATO debt — a zero‑balance integrated client account is the single fastest way to remove an early‑stage risk flag. Third, run a borrowing‑capacity calculation using the actual buffers of short‑ABN lenders (1.5 to 2.0 per cent above the product rate) rather than the old 3‑per‑cent benchmark, so the pre‑approval figure matches what a specialist lender will actually offer.
Where the declared net profit is between $90,000 and $120,000, targeting an LVR of 70 per cent will open the deepest pool of rate options. Above that, a risk fee of 1.5 per cent becomes the norm unless the ABN has passed the 12‑month mark. With APRA’s buffer handbrake now removed, the funding gap for early‑stage sole traders is narrower than it has been since 2018, but the premium for a short history remains real and must be priced into the property search.
