TL;DR
A declaration of income letter is the primary document self-employed Australians use to prove income for a low doc home loan in 2026. Unlike full doc loans that require 2 years of tax returns and ATO notices of assessment, low doc loans allow you to state your gross income on an accountant‑certified declaration. This letter must be on the accountant’s letterhead, show your ABN, confirm your business is trading and solvent, and state your total gross income for the last two financial years. According to the Reserve Bank of Australia’s (RBA) 2026 Financial Stability Review, the low doc segment now accounts for 18% of new housing loan approvals, up from 12% in 2023, driven by gig economy workers and sole traders. The average loan size for low doc borrowers is $640,000, and lenders typically cap LVR at 70% (or 80% with LMI). By using the correct declaration format — and the right words — you can avoid delays, reduce your interest rate loading, and improve your approval odds by up to 40%.
2026 Landscape: Why Income Declaration Letters Matter More Than Ever
The ATO estimates that over 2.4 million Australians are now self-employed (sole traders, partnerships, and company directors). Post-pandemic, the gig economy expanded by 9% year‑on‑year, producing a wave of borrowers with irregular but strong cash flows that tax returns may not fully reflect. Low doc loans exist precisely for this group. APRA’s latest lending data shows the sector processed $34.2 billion in low doc mortgages in FY2025, with an average default rate of 0.92% — only 28 basis points higher than full doc loans. The declaration of income letter is the gatekeeper: a well‑structured letter signed by a CPA/CA can compress your rate premium from 1.8% down to 0.6% above full doc.
Current low doc interest rates (as of June 2026, source: Canstar and lender websites):
| Lender Type | Average Variable Rate | Typical Rate Loading | Max LVR |
|---|---|---|---|
| Major banks (Westpac, CBA) | 7.50% – 7.90% | 1.20% – 1.60% | 70% |
| Non-bank specialists (Pepper, Liberty, Resimac) | 7.00% – 7.50% | 0.70% – 1.20% | 75% – 80% |
| Private lenders & small ADIs | 7.80% – 8.50% | 1.50% – 2.20% | 65% – 70% |
These rates assume a clean credit file and a properly executed income declaration letter. Incomplete or vague declarations may push you into the highest risk tier, increasing your rate by a further 0.50% – 0.80%.
Core Elements Every Income Declaration Letter Must Include
Based on a review of 10 major low doc lender policies in 2026, a compliant declaration must contain:
- Accountant’s details – Full name, practice name, ABN, phone number, email, and professional membership number (CPA, CA, or IPA).
- Borrower’s identification – Your full legal name, ABN, trading name, business structure (sole trader, company, trust).
- Income statement – Total gross income for each of the last two financial years. Some lenders require it broken down between Director’s fees, salary, and dividends. Always provide a combined total if in doubt.
- Solvency declaration – A sentence confirming the business is trading and able to pay its debts as they fall due.
- Responsibility disclaimer – The accountant must state they prepared the information based on management accounts reviewed for the purpose of the loan application.
- Date and wet/digital signature – Dated within 30 days of loan submission. Most lenders now accept digital signatures via DocuSign.
3 Declaration of Income Letter Samples (Adaptable for Any Low Doc Loan)
Below are three ready‑to‑customise samples. Each has been drafted to satisfy the verification checklists of Australia’s top 6 low doc lenders in 2026. Critical rule: Never include the words “estimated” or “projected” in the income figure without an explicit note that these are based on actual management accounts. Lenders and the Australian Securities and Investments Commission (ASIC) interpret those words as “not verified”, which can trigger a full doc request.

[Phone & Email]Lender-Specific Income Declaration Requirements in 2026
Not all lenders treat these letters identically. Based on public credit manuals and broker submission guidelines as of Q2 2026:
- Westpac Low Doc – Requires the borrower to also provide BAS statements for the last 12 months plus the accountant’s declaration. The letter must be no older than 30 days at the time of application.
- ANZ Low Doc – Accepts a declaration of income but cross‑references it with Bank Statements (12 months) to support declared income. If the declared income exceeds 120% of average bank credits, the broker must provide a reconciliation note.
- Pepper Money – One of the most flexible; allows income declaration without BAS or bank statements but charges a risk fee of 1.25% of the loan amount. The declaration must specifically say “based on management accounts reviewed.”
- Liberty Financial – Uses a proprietary “Self‑Employed Income Form” that the accountant must sign. It has a tick‑box for low doc vs full doc, and the accountant must confirm that the income would be likely to be accepted by the ATO if audited.
What Not to Put in an Income Declaration Letter
Avoid these common errors that cause immediate rejection:
- Using the word “estimated” – Unless paired with “as per management accounts.” Instead use “self‑assessed gross income based on bank credits and expenses.”
- Leaving out the accountant’s professional membership number – Nearly 90% of rejections are due to missing CPA/CA/IPA verification.
- Declaring net income instead of gross – Lenders invariably want gross income before tax and expenses. Net profit figures result in a borrowing capacity reduction of up to 50%.
- Stale dates – Letters older than 30–60 days (varies by lender) are considered invalid.
- Incorrect business structure – If you are a trust beneficiary, the letter must confirm distribution income and not mix it with company salary unless properly separated.
How Banks Verify a Declaration of Income Letter
Lenders don’t just file the letter. Their verification process (summarised from broker interviews and credit policy notes) in 2026 involves:
- Accountant Search – The lender checks the ASIC or ATO Tax Agent Register to confirm the accountant is licensed and currently active. If the accountant is deregistered, the letter is void.
- Income Plausibility Check – The declared income is compared against industry benchmarks. For example, a café owner in Sydney declaring $250,000 salary will likely trigger a request for additional documentation unless the ATO benchmarks for that area and turnover support it.
- Bank Statement Cross‑Check – Many lenders (especially the majors) will review 6–12 months of business and personal bank statements to ensure the declared income aligns with credits. A mismatch of more than 30% usually requires a substantial explanation.
- Accountant Confirmation Call – 15% of applications undergo a direct phone verification with the accountant (source: Pepper Money 2025 broker survey). The accountant may be asked, “Did you prepare the income declaration?” and “Would you stand by these figures if questioned by the ATO?”
Q: Can I write my own declaration of income letter?
No. All Australian low doc lenders require a qualified, independent accountant to sign the declaration. Self‑declared income statements have zero value and will lead to an automatic decline. The only exception is some basic “alt doc” products that accept a statutory declaration plus 12 months of bank statements, but the maximum LVR is typically 60%.
Q: What if my accountant refuses to sign the letter?
Accountants may refuse if their professional indemnity insurance or practice standards prevent them from providing forward‑looking statements. Advice: shop around for an accountant who specialises in lending; a specialist mortgage broker can point you to an accommodating practitioner. You can also use a CPA‑minded service that reviews your management accounts for a fee (usually between $300 and $600) and issues a compliant income declaration letter.
Q: How much can I borrow with a low doc loan in 2026 based on an income declaration?
Lenders calculate borrowing capacity like full doc, but often apply a 20–30% haircut to declared income as a safety margin. For example, if you declare $150,000 gross, a non‑bank lender may assess your serviceability on $120,000. Using current interest rate buffers of 3%, the typical borrowing capacity for a single self‑employed borrower with no dependents is approximately 4.5 times the assessed income, minus existing liabilities. Thus, a $120,000 assessed income could support a loan of around $540,000. Banks generally cap low doc borrowing at 70% LVR, meaning you need a 30% deposit plus costs (e.g., a $770,000 property requires a $231,000 deposit plus stamp duty).
5 Critical Tips to Strengthen Your Income Declaration Letter
- Attach a management accounts summary – If you can, have the accountant attach a one‑page profit & loss and balance sheet. Pepper Money data shows that applications with attached management accounts have a 37% higher approval rate.
- Align declared income with bank cash flow – Ensure the gross income corresponds to at least 80% of total credits seen in your business bank statements.
- Use precise, non‑capped language – “The client’s gross income for 2025–26 from trading activities was $X” is far stronger than “The client earned approximately $X.”
- Include a solvency confirmation – It’s a required ASIC‑driven element since 2024; omit it and your letter will be aged out.
- Get a pre‑assessment from a broker – A broker can submit the declaration to their BDM before full application, avoiding a credit enquiry on your file.
Frequently Asked Questions (Q&A Format)
Q: Is a declaration of income letter the same as a CPA comfort letter?
Yes, they are often used interchangeably. A CPA comfort letter is a broader term, but in the context of low doc loans, it must contain the same income declaration, solvency statement, and accountant’s credentials.
Q: Can I use one declaration for multiple lenders?
Yes, provided the letter is not lender‑specific (i.e., not addressed to a particular bank). Most accountants will issue a “To Whom It May Concern” letter that works universally.
Q: What if my income dropped in the current year but was high in prior years?
You must declare the most recent two years. If FY2025–26 was lower, adjust your loan expectations downward. Most lenders use the lower of the two years or an average, depending on policy. Lying about the current year to inflate income is fraud.
Q: Do I need a new income declaration letter for every property purchase?
Yes, each application requires a fresh letter dated within the lender’s validity window (usually 30 days). Old letters will not be accepted.
Q: Are there any no‑doc loans in Australia in 2026 that don’t need this letter?
No‑doc loans (without income documentation) are virtually extinct due to ASIC’s responsible lending obligations. The closest you’ll find is an asset‑based loan or a caveat loan, where the lender relies solely on property equity. Interest rates for these are typically 9%–12% with a maximum LVR of 50%–60%.
Q: How does the income declaration affect my interest rate?
Lenders tier risk by income verification quality. A perfect declaration backed by management accounts may place you in Tier 1 (rate around 7.00%). A minimal declaration without attachments may land in Tier 2 or 3, adding 0.50%–1.20% to your rate. Over a 30‑year loan of $500,000, a 0.80% rate difference costs an extra $88,000 in total interest.
