The pool of self-employed home buyers who cannot produce a consecutive run of PAYG payslips has spent much of 2024 watching their borrowing options narrow. Non-bank lenders that dominated the low-doc segment through the cheap-money years have, since the Reserve Bank began lifting the cash rate in May 2022, closed or capped the pathways that did not demand rigorous third-party verification. At the same time, APRA’s February 2023 letter to authorised deposit-taking institutions, confirming the 3% serviceability buffer would stay while the interest-rate floor moved to 0%, forced even unregulated credit providers to re-weight how they treat declared income. In that tightening, a document many applicants once considered interchangeable—a letter of employment—has split from a document that has become the gatekeeper for self-employed lending: the accountant’s letter. The distinction is no longer cosmetic. A letter of employment, typically issued by a third-party business to confirm a person’s role, tenure, and salary, carries weight only when the borrower can also supply two consecutive years of PAYG income statements or tax returns. An accountant’s letter, drafted according to a lender’s prescribed format, can unlock a low-doc or alt-doc loan when the applicant’s business structure, irregular cash flow, and tax minimisation strategies make standard verification impossible. In a market where Pepper Money adjusted its low-doc DTI cap to 6x on 1 May 2024 and Resimac hardened its alt-doc policy on 1 March 2024, confusing the two documents can cost a self-employed borrower a pre-approval before the full application is lodged.
What a Letter of Employment Actually Verifies—and What It Can’t
A letter of employment is a creditor-side document issued by an employer. Its value lies in confirming that an individual is employed, the nature of that employment (permanent, part-time, casual), the gross annual salary or hourly rate, and the length of the engagement. The letter must appear on the employer’s letterhead and be signed by a person with authority to attest to the facts, typically a director, HR officer, or direct manager. Lenders such as Liberty Financial will accept a letter of employment as a primary verification tool for PAYG borrowers only when it is accompanied by two most recent consecutive payslips and, in some scenarios, the corresponding year-to-date income statement. Without the payslips, the letter alone has no standalone contracting force under the NCCP Act’s responsible lending provisions [ASIC Regulatory Guide 209, last revised March 2023, paragraph 209.67]. It does not prove income actually arrived in the borrower’s account, and no mainstream lender will assess serviceability solely from a signed statement that describes an employment relationship.
Where an Employment Letter Fits in a Full-Doc File
For a full-documentation PAYG borrower, the letter of employment is a subordinate piece. Resimac’s Prime Full Doc policy (effective 1 July 2023) ranks it below payslips and the most recent PAYG summary in the hierarchy of acceptable income evidence. The lender uses the letter to cross-check the salary stated on the payslips and to confirm the borrower has passed any probation period. If the letter states a remuneration different from the payslips, Resimac will use the lower of the two figures. Liberty goes a step further: where income includes regular overtime or allowances, Liberty’s credit guide requires the employment letter to explicitly itemise each component, otherwise those amounts are excluded from the serviceability calculation. The letter therefore acts as a cap rather than a floor.
Why Self-Employed Borrowers Cannot Use One
The self-employed cannot obtain a letter of employment from their own structure that meets lender definition. A sole trader operating under an ABN cannot issue a letter to themselves that a credit assessor would treat as independent. A company director who owns all the shares might draft a director’s confirmation, but that document would fall under accountant’s letter or self-certification rules, not the employment letter pathway. La Trobe Financial’s self-employed credit manual (Version 5.3, November 2023) states explicitly that any document signed by a person with a beneficial interest in the borrowing entity is not an “employer letter” and must be treated as a borrower declaration. That classification immediately pushes the file into alt-doc territory where LVR ceilings and rate loadings apply.
The Accountant’s Letter as a Low-Doc Instrument
An accountant’s letter is a third-party declaration prepared by a qualified professional—a registered tax agent, CPA, or chartered accountant—who has a continuing client relationship with the borrower. Its purpose is not to confirm employment but to attest to the financial sustainability of a self-employed income stream. Lenders in the low-doc and alt-doc segment require the letter to state the borrower’s gross annual income from business operations, confirm that the figure is consistent with the lodged or draft tax returns and BAS statements, and verify that the borrower’s business is solvent and has been trading for a prescribed period, typically two years. The letter must include the accountant’s registration number, details of the professional indemnity insurance held, and a declaration that the accountant has reviewed the financial records. Brighten’s Low Doc Home Loans Product Guide (effective 1 July 2023, updated 15 January 2024) lays out a mandatory template: any deviation voids the document.
How Lenders Use the Letter to Build a Serviceability Picture
When an accountant’s letter is supplied, the originating lender does not simply adopt the stated figure as the borrowing capacity. Most non-banks apply a discount to reflect the uncertainty of self-employed income. Pepper Money, in its Low Doc Self-Employed Loans policy (dated 1 May 2024), permits the letter to support a declared income figure, but the credit assessment applies an 80% haircut to that number if the loan is an 80% LVR product and the borrower cannot also provide 12 months of BAS. The rationale is that BAS contains GST turnover data that can be cross-referenced against the accountant’s assertion. Without BAS, the declared income is treated the same as a borrower statement, carrying a full 100% verification discount, which pushes the effective DTI ratio far higher. Bluestone Mortgages’ Self-Employed Full Doc and Alt Doc policy (effective 4 September 2023) requires the accountant’s letter to contain a statement that “the income declared is sufficient to support the loan repayments” and will scale the accepted income to the lower of the accountant’s figure or the average net profit from the most recent two years’ financials. If both are absent, the loan is rated as near-prime and LVR is capped at 70%.
The Hard Requirements That Trip a File
The formal requirements for the accountant’s letter have hardened since 2022, largely because lenders identified a pattern of short-form letters that offered no verifiable detail. Resimac’s Alt Doc Product Guide (1 March 2024 refresh) now specifies that the accountant must state the basis of income calculation—whether cash, accruals, or director’s fees only—and declare that the business has not suffered a material reduction in revenue in the period since the last lodged return. The letter must be dated within 30 days of application. A file with a stale letter, or one that uses ambiguous phrasing like “the borrower has the capacity to earn” rather than a definite income number, will be declined by Resimac’s automated pre-assessment. Liberty’s self-employed pathway under its Freedom prime product (credit guide April 2024) allows an accountant’s letter as a sole income verification only if the borrower has held an ABN for more than two years and the loan purpose is not construction. Even then, Liberty will cap the LVR at 75% and apply a 2.5% loading to the standard variable rate unless the borrower provides the most recent year’s tax return and notice of assessment. The market price for the convenience of an accountant’s letter is a permanent premium in rate and a lower LVR.
The LVR, DTI, and Buffer Math That Sits Behind the Letters
The choice between a full-doc employment letter and an alt-doc accountant’s letter determines the three critical numbers in any credit decision: maximum LVR, debt-to-income cap, and serviceability buffer. Where a PAYG borrower with a clean credit file might access a 90% LVR loan at a buffer of 3% over the product rate (as required by APRA’s February 2023 directive), the self-employed applicant presenting an accountant’s letter will be constrained to a lower LVR, a lower DTI ceiling, and often a higher effective assessment rate.
LVR Caps Across the Non-Bank Tier
The LVR ceiling is the first gate. Resimac’s alt-doc product set: up to 75% LVR if the sole income verification is an accountant’s letter and the loan amount is below $1 million; the cap drops to 70% for loans between $1 million and $2 million. With two years’ tax returns and an accountant’s letter, that rises to 85% LVR, but the letter then becomes supplementary. Pepper’s low-doc range permits 80% LVR for loans up to $1 million provided the security is a standard residential property in a metropolitan postcode, the borrower has a clean credit history, and both an accountant’s letter and six months of BAS are lodged. Without BAS, the maximum LVR is 65%. Bluestone goes to 75% LVR for self-employed borrowers supplying an accountant’s letter plus 12 months of business bank statements; 70% without. Brighten caps low-doc at 75% LVR for purchases and 70% for refinances, and that cap applies irrespective of whether the file includes BAS, making the accountant’s letter the necessary but not always sufficient condition.
DTI Limits That Kill Peak Borrowing
DTI limits among low-doc lenders have been wound back sharply. Pepper published a debt-to-income ratio cap of 7x in its mid-2023 policy guide; that was reduced to 6x on 1 May 2024 for all low-doc applications. The cap is applied to the gross annual income derived from the accountant’s letter after the lender’s haircut. A self-employed applicant whose accountant’s letter states a gross business income of $150,000 but who supplies no BAS will be assessed on $75,000 of effective income (50% discount), creating a maximum borrowing of $450,000 at a 6x DTI ceiling. Before the May 2024 reset, that same income profile would have allowed $525,000. Bluestone applies a hard 6.5x DTI limit to near-prime alt-doc but also overlays a floor on net monthly surplus of $800 after all commitments, which cuts borrowing capacity below the DTI ceiling in many middle-income cases. La Trobe Financial’s self-employed matrix (v5.3) uses a debt-service-coverage ratio (DSCR) layer: the loan proposal must show a projected DSCR of at least 1.25x on the actual product rate plus a buffer of 2%, which often gets the effective buffer to 10% in a market where variable rates sit around 8% p.a. for low-doc.
Serviceability Buffers and the APRA Overhang
APRA’s serviceability guidance applies only to ADIs, but the major non-banks and warehouse-funded lenders have followed it voluntarily to maintain secondary-market acceptability. The February 2023 APRA letter confirmed that ADIs must assess new borrowers at the higher of the product rate plus 3% or a floor rate of 0%—in practice, the floor is negligible. Non-bank lenders in the low-doc space, however, often apply a lower headline buffer (2%) but compensate with the income haircut. Resimac’s servicing calculator for alt-doc loans uses the product rate plus 2% and then adds the income discount derived from the verification tier. The effect is that an alt-doc loan at 70% LVR with an accountant’s letter carries a total servicing threshold that is approximately equivalent to a 5% buffer on the gross declared income, because only 60% of that income is fed into the calculator. A PAYG borrower with an employment letter and full payslips enjoys 100% income recognition at a 3% buffer. The gap is substantial: for a $100,000 declared income, the effective income entering servicing is $100,000 versus $60,000, before the buffer differential is even applied.
Choosing the Right Letter for a Specific Loan Purpose
Borrowers and brokers who treat the accountant’s letter as a fallback rather than a deliberate strategy often end up with a rejected deal simply because the loan purpose or security type clashes with the lender’s low-doc appetite. An accountant’s letter does not work for every scenario, and an employment letter cannot be manufactured where no employer relationship exists.
Purchase Versus Refinance: Different Tolerance
Non-bank lenders impose tighter limits on refinance applications for self-employed borrowers using an accountant’s letter. Brighten’s low-doc policy draws a clear line: purchases can access 75% LVR with an accountant’s letter, while cash-out refinances are capped at 70% LVR and the maximum cash-out is $250,000. La Trobe’s self-employed range does not allow an accountant’s letter alone for an equity release unless the borrower can demonstrate six months of GST-inclusive BAS turnover that aligns with the declared income. If the purpose is business investment, Bluestone will accept the letter only when accompanied by a letter from a qualified financial planner or business advisor confirming the viability of the investment, a requirement that does not exist for a PAYG borrower using an employment letter for a similar purpose.
Loan Size Thresholds
An accountant’s letter becomes less effective as the loan size rises above $750,000 because most non-bank lenders increase their documentation requirements at that breakpoint. Resimac’s alt-doc product allows a straight accountant’s letter plus BAS for loans up to $750,000; for a $1 million loan, two years’ full financials are mandatory even if an accountant’s letter is also supplied. Pepper’s low-doc 80% LVR is available only for loans up to $1 million; above that, the maximum LVR drops to 70% and the accountant’s letter must be accompanied by the most recent year’s tax return and notice of assessment. Liberty’s self-employed low-doc pathway stops at $1.5 million and then only if the borrower submits the last two years’ tax returns; the accountant’s letter alone is acceptable only for loans of $750,000 or less.
Asset-Lend and Exceptions
The asset-lend pathway, where the borrowing capacity is determined by the borrower’s net asset position rather than income, largely removes the need for either letter. However, Brighten’s asset-lend product (effective 1 July 2023) still requires a letter of employment if the applicant also has PAYG salary income that is being used to support serviceability for the surplus test. La Trobe’s asset-based lending demands no income verification at all, which renders both documents irrelevant, but the LVR is limited to 60% and the maximum loan is $2 million. For a self-employed borrower who can show substantial assets but modest taxable income, this route can bypass the income verification problem entirely, at the cost of a higher interest rate and a lower LVR.
What a Self-Employed Borrower Should Do Right Now
Navigating the letter split is not a one-time document exercise; it is a sequence of pre-application decisions that lock in the available LVR and rate. Five specific steps can reduce the risk of a declined pre-assessment and avoid paying a low-doc premium when a full-doc pathway is accessible.
Map the income to the closest verification ladder. Before approaching a lender, check whether the most recent two years’ personal tax returns and notices of assessment show a taxable income that can support the required loan amount at a 3% buffer and 100% income recognition. If they do, a full-doc application with an employment letter (if any PAYG component exists) or the full tax return package for the self-employed will deliver a higher LVR and a lower rate than any alt-doc alternative.
Have the accountant draft the letter to the lender’s exact template and not a generic “to whom it may concern.” Each lender’s template contains specific wording about income being sufficient to meet the proposed repayments and being consistent with lodged financials. A generic letter will be rejected even if the numbers are identical, wasting the 30-day validity window that Resimac and others enforce.
Always pair the accountant’s letter with BAS where possible. A file with an accountant’s letter and no BAS will attract the highest income haircut—typically 50% or more—at every major low-doc lender. Six months of quarterly BAS (two quarters) lifts the effective income recognition at Pepper from 50% to 80%, and 12 months moves Bluestone from 70% LVR to 75% LVR. The effort is small relative to the borrowing power gain.
Know the DTI clock is running downward. Pepper’s move from 7x to 6x demonstrates that DTI caps are not stable. If a deal is marginal at a 6x DTI ceiling, a further lender-driven cut to 5.5x could extinguish it. Structure the application early, obtain a pre-approval that locks in current policy, and set a settlement date within the pre-approval validity period, which is typically 90 days for non-banks.
For loans above $750,000, prepare to supply two years’ financials. The accountant’s letter alone will not open the top LVR tiers at this loan size. Pre-lodging the tax returns, even if they show a modest taxable income, allows the lender to use the accountant’s letter as supplementary comfort rather than the sole income source, which changes the underwriting category from low-doc to a hybrid alt-doc where LVRs can still reach 80% with a lower rate premium.
