The self-employed lending segment has entered a period of quiet but consequential tightening around the single most basic metric on a borrower’s file: how long their Australian Business Number has been active. Since mid-2024, multiple non-bank and specialist lenders have recast their ABN duration minimums, not through headline product changes, but via revised credit guides and servicing overlays. The shift coincides with APRA’s July 2024 serviceability guidance, which nudged lenders to apply more rigorous expense floor assumptions to borrowers with less than two years of trading history. For sole traders, contractors, and company directors who structure income through an entity, the date an ABN was registered — and whether it has been continuously active — now determines not only which loan product is available but also the maximum loan-to-value ratio and the applicable interest rate loading. A six-month ABN can still unlock finance, but the path has become narrower, more document-intensive, and almost exclusively limited to asset-lend or private-label solutions. Meanwhile, the mainstream alt-doc and low-doc offerings from Pepper Money, La Trobe Financial, Liberty, Resimac, Bluestone, and Brighten each enforce distinct active-period thresholds, none of which align perfectly. The result is a credit market where a difference of 30 days in ABN registration can alter a borrower’s LVR from 80 per cent to 60 per cent, or disqualify them from prime-priced debt entirely.
The Baseline: What Lenders Count as ‘Active’
Continuous Active Period Versus GST Registration Date
Most lender credit assessors begin the clock from the ABN’s effective registration date listed on the Australian Business Register, not from the date an applicant started trading in practice. That distinction matters. The ABR records two key dates: the registration date and, separately, the GST registration date if applicable. Lenders in the low-doc space overwhelmingly use the ABN registration date to calculate the “time in business” because it is the only independently verifiable timestamp on the public register.
Pepper Money’s Alt-Doc Lending Policy v4.2, effective 1 October 2024, explicitly states that its 12-month minimum active period is measured from the ABN registration date, and any gap in registration — even a few weeks — resets the clock. La Trobe Financial’s Credit Guide, published November 2024, includes a similar continuity requirement but allows a bridging argument if the ABN was cancelled and reinstated within the same calendar year due to administrative error, provided a letter from the Australian Tax Office confirms no trading interruption.
The practical consequence: borrowers who registered an ABN years ago but only recently began earning revenue under that ABN cannot use their full registration history unless they can demonstrate the ABN was continuously used for business purposes. ATO portal screenshots, BAS lodgement histories, and tax return notices of assessment become the evidence. Liberty’s low-doc application checklist, updated 1 December 2024, requires a minimum two-year BAS lodgement trail for any borrower claiming more than 24 months of ABN activity. If only one year of BAS is available, the ABN is treated as having 12 months’ seasoning, irrespective of the registration date.
Why Two Years Is the Line Between Prime and Non-Prime
Two years of continuous ABN activity remains the unofficial threshold separating full-doc-like low-doc pricing from true risk-premium lending. Prime-variant low-doc products — where pricing falls within 30 to 40 basis points of equivalent full-doc loans — are almost universally conditional on an ABN active for at least 24 months. Liberty’s Prime Low Doc product requires two years of ABN and GST registration, plus the most recent notice of assessment matching declared income. Resimac’s Specialist Alt Doc tier, per its product note effective 15 September 2024, accepts 24 months of ABN registration with only one year of tax returns, but the LVR cap rises to 70 per cent from 60 per cent for shorter histories.
At the sub-24-month mark, the buffer rate servicing calculation shifts. APRA’s letter to ADIs dated 15 July 2024 advised that for borrowers with less than two years of self-employment income evidence, lenders should apply a minimum 2.0 percentage point serviceability buffer above the loan product rate — up from the standard 1.0 point — when using the household expenditure measure floor. Non-ADIs are not strictly bound by APRA, but specialist lenders have adopted similar overlays to manage warehouse and aggregator risk appetites. Bluestone’s near-prime alt-doc credit guide, version 7.0, issued February 2024, embeds a 2.25-point buffer for ABN histories under 24 months, which pares maximum borrowing capacity by roughly 12 to 15 per cent compared with a full-doc assessment.
State-Based Exceptions for Certain Industries
A small carve-out exists for specific geographies and sectors, although it rarely appears in advertised product sheets. Brighten’s mortgage manager policy memo, circulated 30 January 2025, notes that applicants with ABNs registered in regional postcodes for agricultural, medical, or aged-care businesses may have the two-year requirement relaxed to 18 months on a case-by-case basis, subject to an LVR reduction to 55 per cent. The concession reflects a long-standing view among credit risk teams that these sectors generate steadier cash flows even during the establishment phase, but it is not underwritten consistently across all aggregators.
These qualitative allowances are documented in internal credit manuals rather than public marketing material, so brokers must interrogate individual lender BDMs. A self-employed grain farmer in the Wimmera who has held an ABN for 20 months but has already lodged two BAS cycles and one full-year tax return stands a far better chance at a policy exception than an inner-city marketing consultant with the same timeline.
The 12-Month Tier: Alt-Doc and BAS-Only Pathways
Pepper Money and Resimac: The 12-Month Floor
The 12-month ABN active period has become the practical floor for nationally available, risk-rated low-doc loans with LVRs above 60 per cent. Pepper Money’s Alt-Doc product accepts ABN registration of 12 months, evidenced by the ABN lookup and one full-year tax return or BAS statement covering at least one June quarter. The maximum LVR under Pepper’s policy, effective 1 October 2024, is 75 per cent for purchases and 70 per cent for refinances, with pricing margins starting at 2.95 per cent p.a. above the applicable Pepper reference rate. For loans above 70 per cent LVR, Pepper also requires a mortgage insurer file note, which effectively imposes a back-end credit check that can filter out borderline applications.
Resimac’s Alt Doc Lite, detailed in its Product Parameter Sheet dated 15 September 2024, also settles at a 12-month ABN minimum, but the documentation suite is narrower: a letter from a registered tax agent verifying income derived from the business, plus the latest BAS, is sufficient. Resimac caps LVR at 65 per cent for metropolitan properties and 55 per cent for regional, postcode-dependent. This product class suits borrowers whose income is stable but not fully reflected in a single tax return — for example, a subcontractor whose construction income spiked only in the most recent six months after a slow start.
La Trobe and Liberty: The Documentary Overlays
La Trobe Financial’s Low Doc Light product, as described in its November 2024 Credit Guide, expects an ABN active for a minimum of 12 months but will also accept an accountant’s declaration of income in lieu of BAS if the accountant is a registered tax agent and the declaration is dated within 30 days of application. The interest rate loading for that declaration pathway is an additional 0.45 per cent p.a. above the standard Low Doc rate, reflecting the weaker verifiability. Borrowers who can supply a full year’s tax return avoid the loading.
Liberty’s Alt-Doc variable rate loan, per its December 2024 update, takes a different approach. It requires an ABN active for 12 months but compels the applicant to complete a self-certified income declaration that is cross-checked against industry benchmarks derived from ATO small-business benchmarks. If the declared income exceeds the benchmark’s top quartile, Liberty requests a tax agent statement regardless of LVR, adding three to five business days to the assessment timeline.
These overlays illustrate an operating principle: at the 12-month mark, credit teams accept thinner income evidence but compensate with higher pricing, lower LVRs, or extra documentation triggers that can slow approval when the deal looks atypical.
The Six-Month Hard Edge: When It Is Still Possible
Asset-Lend and Private Funders
A six-month ABN history now sits almost entirely outside regulated low-doc products with LVRs above 50 per cent. The exception is the asset-lend channel, where loan serviceability is not assessed on income at all and the primary underwriting basis is the property’s value and the borrower’s exit strategy. Bluestone’s near-prime asset-doc loan, policy version 7.0 issued February 2024, allows six months of ABN registration provided the loan-to-value ratio does not exceed 50 per cent and the borrower can demonstrate six months of loan repayments in a dedicated savings account. The interest rate sits around 7.45 per cent p.a. variable, roughly 300 basis points above standard near-prime variable rates.
Private funders — unrated credit funds and high-net-worth syndicates — occasionally write loans at 45 to 50 per cent LVR for ABNs active for as little as three months, but the pricing breaks into double-digit territory. These loans are typically six to 12-month bridge facilities with an upfront establishment fee of 2.0 to 2.5 per cent of the loan amount and a yield north of 9.5 per cent p.a. They are appropriate only for borrowers with a clear liquidity event in sight, such as the sale of a business or property completion.
Fresh ABN With Seasoned Industry Experience
A narrow door remains open at the regulated lender level when an applicant has just registered an ABN but can demonstrate multiple years of prior experience in the same trade as an employee. Brighten’s policy memo of 30 January 2025 introduces a “Priors Recognition” addendum for medical and trade professionals, where a registered ABN of six months can be paired with at least two years of PAYG payslips, references, or licences proving the same occupation. The maximum LVR under this concession is 55 per cent, and the loan must be assessed at a floor interest rate of the current lender variable rate plus 1.50 per cent for buffer purposes, compressing borrowing capacity.
Brighten will only accept this pathway for applicants holding an ABN in the health, construction, or IT sectors, where skill portability is validated by external credentials. A self-employed electrician who spent four years as a subcontractor on wages before registering an ABN to contract directly therefore qualifies, whereas a former marketing manager starting a consulting firm in a different sector does not. This distinction means the ABN date alone is insufficient; the narrative must be pre-packaged with documentary proof of industry continuity.
