How to Apply for a Mortgage as a Freelancer with Multiple ABNs

Freelance income derived through multiple Australian Business Numbers (ABNs) has long been a blind spot in Australia’s mortgage underwriting. The major banks’ serviceability calculators were built for a single employer–single ABN world; they break down when a sole trader shows three separate GST-registered entities covering consulting, e-commerce and a sporadic subcontracting gig. For years, the default industry response was to tell the borrower to consolidate entities or simply ignore secondary ABNs, which understated actual income and unfairly restricted borrowing capacity. That posture is now shifting. The trigger is not new regulation but a cascade of lender policy tweaks that began in late 2023, as non-bank funders moved to capture the growing pool of multi-entity sole traders and company directors abandoned by the Basel III–driven tightening of the major banks’ self-employed lending frameworks. APRA’s October 2024 quarterly property exposure statistics confirmed that non-ADI lenders lifted their owner-occupied loan books by 9.4% year-on-year, with alt-doc and low-doc originations accounting for the bulk of the growth. Meanwhile, the Reserve Bank of Australia’s cash rate target of 4.35% (held since November 2023) has kept serviceability buffers high, making the recognition of every dollar of verifiable income more critical than ever. For a freelancer running two ABNs who files quarterly Business Activity Statements (BAS), the difference between having one entity assessed versus both can translate to a borrowing capacity swing of $80,000–$150,000 depending on the net profit split. This article maps the precise lender policies — Pepper Money, La Trobe Financial, Liberty, Resimac, Bluestone and Brighten — that now allow multiple-ABN income aggregation under alt-doc and low-doc frameworks, sets out the documentation standards each demands, and provides the arithmetic an applicant needs to estimate a maximum loan size before filing a pre-assessment.

Why Multiple ABNs Create a Document Hang-up for Conventional Lenders

The core friction is evidentiary. A typical Prime full-doc application demands two years’ personal tax returns and Notice of Assessments. For a sole trader with three ABNs, the individual ATO tax return reports only the aggregated business income at the “Business and professional items” schedule; the separate GST-registered entities are invisible unless the applicant also supplies profit-and-loss statements for each ABN. Most major banks will not accept separate P&Ls as primary income evidence unless the accountant is an ASIC-registered tax agent and the documents are accompanied by an integrated tax return — and even then, credit assessors often average income over two years for each entity, penalising growth spikes. A freelancer who launched a second ABN 14 months ago and generated $52,000 of net profit in the most recent financial year will frequently be told that income is ineligible because two years’ history is unavailable. The consequence is a systemic under-counting of income that pushes many multiple-ABN borrowers toward the non-bank alt-doc channel.

The Serviceability Maths: Aggregation versus Averaging

Consider a freelancer operating ABN 1 (consulting, net profit $78,000 p.a. averaged over two years) and ABN 2 (e-commerce, net profit $44,000 in FY2024 only). Under a conservative two-year averaging rule, only $22,000 of the e-commerce profit is recognised, giving a total assessable income of $100,000. If a lender aggregates the most recent year’s figures for both entities and applies an alt-doc discount of 20% on non-PAYG income, the assessable income becomes ($78,000 + $44,000) × 0.80 = $97,600. While the raw number is slightly lower, the lender’s serviceability calculator is applied to a single-year snapshot that may better reflect current cash flow, and the secondary ABN’s full contribution is acknowledged. With an assessment rate of 9.5% (the typical alt-doc floor, incorporating a 3% buffer over the actual rate) and a $25,000 annual living expense allowance, the difference between $100,000 and $97,600 is trivial, but when the freelancer’s ABN 2 profit was instead $90,000 and ABN 1 averaged $60,000, the alt-doc approach yields assessable income of $120,000 versus $105,000 under conservative averaging — a $15,000 uplift that funds an additional $100,000 of debt at a 5.5 DTI cap.

Lender-by-Lender Policy on Multiple ABN Income Recognition

Non-bank lenders have each carved distinct positions on how many ABNs they will assess, what documents they require, and which LVR and DTI caps apply. The policies detailed below are current as of late 2024. All dollar figures are in Australian dollars, and all interest-rate references are to standard variable alt-doc rates unless otherwise noted.

Pepper Money: Aggregation through an Alt-Doc Master Declaration

Pepper Money’s Advantage Plus alt-doc product allows a single borrower to list multiple ABNs within the one application provided the entity structure is identical across all ABNs (e.g., all sole trader, or all single-director private company). As of November 2024, Pepper’s underwriting guidelines specify:

• Document requirement: Quarterly BAS lodged within six months of the current quarter for every ABN, plus an accountant’s letter confirming gross income and net operating profit for each entity for the most recent financial year. No tax returns are mandatory if the borrower is GST-registered for 12 months or more.
• Income calculation: The annualised liable revenue from the most recent four quarterly BAS statements (or two half-yearly statements) for all ABNs is summed, then multiplied by the profit margin declared in the accountant’s letter. If an ABN is less than 12 months old, Pepper accepts a minimum six months’ BAS history and will annualise on that basis with a 10% income haircut.
• LVR and DTI: Maximum loan-to-value ratio 80% without LMI (owner-occupied) and 75% for investment. The debt-to-income ratio is capped at 6.0x for borrowers with a clean credit file; 5.0x where there is a prior paid default more than two years old.
• Assessment rate: 9.00% p.a. (product rate + 2.50% buffer).

A practical example: A freelancer with ABN 1 (registered 2019, accountant letter net profit 55%) and ABN 2 (registered January 2024, accountant letter net profit 40%) has trailing BAS turnover of $143,000 and $68,000 respectively. The summed liable revenue is $211,000. Pepper applies a blended profit margin of (0.55 × $143,000 + 0.40 × $68,000) / $211,000 ≈ 49.8%, yielding an annualised profit of $105,078. The 10% haircut on ABN 2’s contribution reduces the marginal income to $100,600 before the alt-doc discount of 20%, leaving an assessable income of $80,480. Even after the discount, that figure is often superior to the alternative of dropping the second ABN entirely.

La Trobe Financial: The “Self-Employed Extra” Tier for Multi-Entity Borrowers

La Trobe Financial introduced its “Self-Employed Extra” tier in March 2024, designed explicitly for borrowers with multiple active ABNs or complex trust structures. Key parameters:

• Eligible entities: Sole traders, partnerships, companies and unit trusts — but each entity must have a distinct ABN and be trading in the same core industry sector. La Trobe will not aggregate crossing industries without a commercial letter from a qualified accountant explaining the synergy (e.g., a photographer with separate ABNs for wedding and real estate photography is typically acceptable; a plumber who also runs a café is not).
• Evidence: Six consecutive weekly or fortnightly bank statements showing the deposit of gross revenue for each ABN, plus the most recent individual tax return (only the front-page summary is required; no detailed P&L). An accountant declaration is compulsory, certifying that all ABNs are current, their GST registration status, and the borrower’s ownership percentage.
• Income calculation: The lower of the bank-statement-verified average monthly deposits (annualised) and the accountant-declared gross profit, with a standardised expense ratio of 35% applied to the gross unless a higher ratio is justified by the accountant. For instance, if bank statements show $15,000/month total deposits across two ABNs and the accountant declares total gross revenue of $190,000 p.a., the lower figure is $180,000 annualised from bank statements. La Trobe then deducts 35% for expenses, leaving $117,000 before the alt-doc discount of 20%, yielding $93,600 assessable.
• LVR and rate: Up to 75% LVR on a standard variable rate of 6.99% p.a. (comparison rate 7.32% p.a.) for loans up to $1,500,000. The assessment rate is the product rate plus 2.25%, i.e., 9.24% p.a. La Trobe imposes no explicit DTI cap on Self-Employed Extra loans, instead relying on a net surplus test with a 1.25x coverage ratio.
• Dated change: On 1 March 2024, La Trobe raised the maximum loan size for this tier from $1,000,000 to $1,500,000 and reduced the expense ratio from 40% to 35% for metropolitan postcodes.

Liberty Financial: Multiple ABNs under the Liberty Sharp Alt-Doc

Liberty’s Sharp alt-doc suite, refreshed in July 2024, caters to self-employed applicants who can demonstrate consistent revenue but lack two years’ tax history. For multiple ABNs, Liberty’s approach is to treat each ABN as a separate income stream and allow the borrower to “stack” them.

• Documentation: BAS for the most recent four quarters for each ABN, or, if an ABN has traded for less than four quarters, a minimum of two quarterly BAS plus a projected year-to-date P&L signed by a registered tax agent. Liberty does not accept bank statements alone for alt-doc income verification; BAS is compulsory.
• Aggregation rule: Income from each ABN is calculated as annualised liable revenue from the BAS times the profit margin declared in the tax agent’s letter. If the aggregate liable revenue across all ABNs exceeds $500,000 p.a., Liberty requires the applicant to switch to a full-doc application with two-year returns; the alt-doc pathway is only available for total GST turnover under $500,000.
• LVR and assessment: Maximum LVR 80% (no LMI) for owner-occupied principal-and-interest loans. Investment loans cap at 70% LVR. The assessment rate is 8.75% p.a. (rate + 2.50% buffer). DTI cap: 7.0x, calculated against the total alt-doc-assessed income.
• Important nuance: Liberty’s sharp alt-doc does not automatically apply a blanket 20% income haircut; instead, the assessable income is the lesser of the BAS-annualised profit and the tax agent’s declared net profit, without a further ad hoc discount. That yields a higher income figure for a freelancer whose BAS already reflect strong cash flow.

Resimac: The “Near-Prime” Alt-Doc Path for Multiple Entites

Resimac’s near-prime offering (SmartSuite Alt-Doc) underwent a material policy update on 15 August 2024, expanding the acceptance of multiple ABNs. The revised guidelines state:

• ABN rule: A maximum of three active ABNs may be declared. All ABNs must have been GST-registered for at least 12 months, with no exceptions for newer entities.
• Income verification: 12 months’ BAS (four quarterly statements) for each ABN, plus an accountant’s letter. Resimac calculates net assessable income by taking the lower of: (a) the sum of BAS-derived annualised total revenue for all ABNs multiplied by the accountant-declared aggregate profit margin; or (b) the sum of the accountant’s stated net profit for each ABN. That figure is then discounted by 20% to arrive at the alt-doc assessable income.
• LVR: 70% for owner-occupied, 65% for investment, with a maximum loan amount of $1,000,000 per security. LMI is required above 60% LVR, but Resimac’s commission-free LMI arrangement can keep the cost below $3,500 for a $700,000 loan.
• Rates and buffer: As of November 2024, the SmartSuite Alt-Doc variable rate is 7.29% p.a. (comparison rate 7.51% p.a.). The serviceability buffer is 2.00%, giving an assessment rate of 9.29% p.a. Resimac applies a hard DTI limit of 6.5x regardless of credit score.
• Practical restriction: Because all ABNs must have 12 months’ GST registration, a freelancer who just started a second ABN will either need to wait or fund that income stream through a separate asset-lend application.

Bluestone Mortgages: Asset-Lend and Low-Doc Hybrid for Complex Income

Bluestone does not offer a traditional alt-doc product with BAS aggregation. Instead, its low-doc pathway (Cignifi Low Doc) relies on an accountant’s declaration of income without requiring tax returns or BAS, making it inherently agnostic to the number of ABNs. However, Bluestone caps low-doc LVR at 60% and charges a premium rate. For a freelancer with multiple ABNs, the more relevant option is often Bluestone’s asset-based loan: the Prime Asset Line, which assesses serviceability purely on the income derived from the borrower’s asset pool (typically liquid assets or property equity). As of December 2024:

• Asset-lend LVR: Up to 70% on a prime residential security, with a loan size up to $2,000,000. Serviceability is calculated on a deeming rate of 5.50% p.a. applied to the asset value; no other income documentation is required.
• Low-doc component: If the asset pool is insufficient but the borrower wants a higher LVR, Bluestone allows a split-structure loan: up to 60% LVR via low-doc using an accountant’s income declaration (any number of ABNs, gross income declared in a single letter) and the balance via asset-lend up to 70% LVR blended. The blended LVR cap is 65% overall.
• Cost: Variable rate from 7.14% p.a. (comparison rate 7.42% p.a.) with a 2.25% buffer for serviceability, leading to an assessment rate of 9.39% p.a. No DTI limit on asset-lend; low-doc portion subject to a 6.0x DTI cap on the declared income.

Bluestone’s framework is advantageous for a freelancer whose multiple ABNs generate irregular or lumpy income that cannot be neatly annualised from BAS, because the asset-lend component bypasses income verification altogether.

Brighten: Alt-Doc for “Parallel” ABNs with Lender’s Own CRM Data

Brighten Home Loans launched its “MultiStream” alt-doc product on 1 May 2024, targeting freelancers with parallel ABNs. The product is not publicly available through all aggregators; it is distributed via Brighten’s proprietary broker portal and requires pre-assessment using Brighten’s internal customer relationship management data. Key attributes:

• Document standard: 12 months’ bank statements from a single business transaction account that consolidates revenue from all ABNs, plus an accountant’s letter itemising the net profit contribution of each ABN for the last financial year. Brighten will not accept separate bank accounts for each ABN — a consolidated account is mandatory because the lender uses machine-learning models to analyse cash flow consistency across streams.
• Income calculation: The average monthly deposit of the consolidated account over 12 months, annualised, with deductions of 30% for expenses (or the actual expense ratio from the accountant’s letter if higher). The resulting net figure is reduced by a 15% alt-doc discount. There is no manual exclusion of any ABN, because the model is trained to detect and classify income from distinct source patterns.
• LVR, rate, DTI: 75% LVR owner-occupied, 70% investment. Interest rate for loans under $800,000 is 6.79% p.a. (comparison rate 7.05% p.a.); above $800,000, 7.09% p.a. (comparison rate 7.38% p.a.). Assessment rate is the product rate plus 2.50%. DTI cap: 5.5x for loans over $500,000, 6.0x for loans below.
• Eligibility trigger: The applicant must have at least two ABNs that have been active for 18 months and must show at least $80,000 in combined annualised net income after the 30% deduction. Brighten’s July 2024 pricing update reduced the rate by 20 basis points for applicants with a credit score above 680 (Equifax).

Structuring a Multiple-ABN Application: Documentation and Timing

The common thread across all lenders is that separate ABNs must be independently verifiable. Submitting a single accountant letter that lumps all entities together without itemisation will cause the application to be declined or assessed on the lowest-confidence income stream only. A well-prepared file contains:

• A schedule of active ABNs with registration dates, GST status, and principal business activity codes.
• For each ABN, the most recent BAS lodged (or two if required) and, where applicable, a corresponding MYOB/Xero transaction summary.
• A single accountant letter that declares for each ABN: total sales, gross profit, net operating profit, and percentage of ownership. The letter must be on the accountant’s letterhead, dated within 30 days, and explicitly state that the ABNs are current and the GST registrations are active. Many lenders (La Trobe, Pepper, Resimac) will reject an accountant letter that says only “the client’s total income from all sources is $X.”
• Evidence of GST registration history. An ASIC or ABN Lookup extract is not sufficient on its own; the lender may require a screenshot of the ATO portal showing the registration start date.

Timing the Application around BAS Lodgement Cycles

Freelancers with multiple ABNs often lodge BAS at different frequencies — one quarterly, one monthly. The optimal moment to apply is within 30 days of lodging the most recent BAS for all entities, because lenders treat the latest BAS as the primary evidence of current turnover. If a freelancer applies two months after the last BAS was lodged and turnover has surged, that increase is invisible. Conversely, applying immediately after a seasonally weak quarter (e.g., January–March for a freelancer in events) can lower the annualised figure. The solution is to provide a letter from the accountant projecting year-to-date revenue based on bank transactions, but not all lenders accept projections. Liberty explicitly refuses projected P&Ls for alt-doc unless the ABN is new; Resimac requires a 12-month history, so projections are moot. For a Brighten or Pepper application, however, a well-documented projection can be used to supplement the most recent BAS if the bank statements corroborate the trend.

The Cost of Ignoring a Secondary ABN

Dropping a profitable second ABN from the application because the lender’s default calculator cannot handle it is arguably the most expensive mistake a freelancer can make. With an assessment rate of 9% p.a. and a typical $35,000 annual expense baseline, every $10,000 of additional assessable income translates to roughly $69,000 of borrowing capacity at a 6.0x DTI. For a freelancer whose secondary ABN net profit is $50,000, the borrower loses approximately $345,000 in loan size by not documenting it. At an 80% LVR, that means forgoing a $431,250 property purchase. In Sydney’s median dwelling price environment ($1,193,000 as of CoreLogic’s November 2024 Hedonic Home Value Index), that gap can be the difference between buying an apartment and remaining priced out.

Actionable Steps for Freelancers with Multiple ABNs

1. Itemise every active ABN in the initial loan submission. Provide a separate coversheet with registration date, GST status and accountant-verified net profit for the most recent fiscal year. Do not bury entities in the main application form.
2. Lodge the most recent BAS for all ABNs before applying, even if that means accelerating the lodgement cycle by a week. A lender’s credit analyst will not accept an un-lodged draft, and a stale BAS can understate turnover by months.
3. Choose the lender based on the age of the newest ABN. If an ABN is only six months old, Pepper Money or Brighten are the only candidates that will accept partial-year history with a haircut; La Trobe and Resimac require 12 months. If the total GST turnover exceeds $500,000, Liberty’s alt-doc is unavailable, so steer to La Trobe or Bluestone’s asset-lend.
4. If bank statements are cleaner than BAS, target La Trobe’s Self-Employed Extra or Brighten’s MultiStream, both of which rely on cash-flow data. But note the consolidated-account requirement for Brighten — separate business bank accounts will disqualify.
5. Use a blended structure when LVR needs are above 70%. A Bluestone split loan (low-doc 60% plus asset-lend 70% blended) can reach a 65% overall LVR without triggering LMI, while Brighten and Pepper offer up to 75%–80% without LMI on a pure alt-doc basis. Run the numbers on actual loan amount first, because LMI at Resimac’s 70% LVR might be cheaper than a higher rate on an uninsured product at a lower LVR, particularly for loans under $700,000.
