Alt-Doc Lending: What Your Accountant's Letter Actually Does

If you are self-employed and have applied for a home loan through a bank, you already know the problem. Banks assess your income based on your tax returns - the same returns your accountant has carefully structured to minimise your taxable income. The result is a borrowing capacity that bears no resemblance to your actual financial position. Alt-doc lending solves this by using different evidence of income. But the quality of that evidence - particularly your accountant's letter - determines whether your application succeeds or fails.

What the accountant's declaration must contain

An accountant's declaration is not a casual reference letter. It is a formal document that non-bank lenders rely on to verify income in the absence of tax returns. To be accepted, the declaration must typically include the borrower's full legal name and ABN, the name and structure of the business, the period of income being declared (usually the current or most recent financial year), the gross and net income figures, confirmation that the accountant has access to the business's financial records, and the accountant's registration details including their CPA or CA membership number and ASIC registration.

The declaration must be signed on the accounting firm's letterhead. Most lenders require the accountant to be a registered CPA, CA, or IPA member - a bookkeeper's letter will not be accepted. Some lenders also require the accountant to have been acting for the borrower for a minimum period, typically 12 months.

Income shading and what it means for your borrowing capacity

Non-bank lenders do not take the declared income figure at face value. They apply income shading - a discount to the declared figure that reflects the inherent uncertainty of self-employed income. Shading rates vary by lender but typically range from 10% to 20%. If your accountant declares income of $180,000, a lender applying a 15% shade will assess you on $153,000. This is still dramatically better than the $95,000 a bank might assess based on your tax return - but it means the declared figure needs to be accurate and defensible.

BAS statements as supporting evidence

Most non-bank lenders require the last four quarters of Business Activity Statements as supporting documentation alongside the accountant's declaration. BAS statements serve as an independent cross-check - if your accountant declares income of $200,000 but your BAS statements show GST turnover consistent with revenue of $120,000, the lender will question the discrepancy. The BAS and the declaration need to tell a consistent story. Your accountant should review both documents together before you submit your application.

Common mistakes that delay or kill applications

• Vague income figures: Declaring income as a range ("between $150,000 and $200,000") is not acceptable. Lenders require a specific figure for a specific period.
• Mismatched periods: The accountant's declaration covers the 2025 financial year, but the BAS statements are from a different period. Every document needs to align.
• Unregistered accountant: The declaration is signed by a bookkeeper or an accountant who is not a current CPA, CA, or IPA member. The application will be returned immediately.
• Undisclosed liabilities: The borrower has ATO debt, director guarantees, or business lending that was not disclosed upfront. These surface during credit assessment and can result in a decline after weeks of processing.
• Insufficient ABN history: Most lenders require a minimum of 12 months ABN registration. Some require 24 months. Applying before you meet the threshold wastes time.

The difference between a good application and a rejected one

Alt-doc lending is not a shortcut. It is a different documentation pathway that requires precision. The accountant's declaration is the centrepiece of the application, and it needs to be prepared with the lender's specific requirements in mind - not as a generic letter. Different lenders have different templates, different shading policies, and different thresholds for what they will accept.

Anbi works with your accountant to ensure the declaration meets the specific lender's requirements before submission. This coordination between broker, borrower, and accountant is what separates applications that settle from applications that stall.

If you are self-employed and your bank has told you that your borrowing capacity is too low, alt-doc is likely the solution. But executing it properly requires understanding which lender suits your profile, what documentation they need, and how to prepare your accountant for what is required. That is where professional guidance makes the difference between a smooth approval and months of frustration.
