One Doc Home Loans for Manufacturers (2026): How Factory Owners Use One Accountant's Letter Instead of Two Years of Tax Returns
The Misconception — Tax Returns Must Reflect Reality
Most manufacturers think their tax returns need to match reality for a home loan. They don't. In fact, many factory owners are caught in a trap: they earn strong cash, but their tax returns look thin because they reinvest profits back into equipment, staff, or stock. A lender looks at the bottom line — taxable profit — and sees a number that doesn't reflect the business's ability to service a home loan.
One Doc sidesteps this entirely. Instead of relying on tax returns alone, lenders accept an accountant's letter that verifies actual income — often much closer to reality than a tax return.
One Doc Path
Cleaner. Single accountant's letter. No need for two years of returns. Timeline: 2–3 weeks. Income verified by qualified CPA. Works for manufacturers with strong cash but thin tax returns.
Traditional Full-Doc Path
Messier. Two years of tax returns required. Limited to taxable profit only. Timeline: 4–6 weeks. Disadvantages factory owners who reinvest.
How the Accountant's Letter Works
The accountant's letter is a formal document from your CPA that states your income based on the business's financial records. It's not a guess — it's a professional verification. Lenders use it alongside your bank statements to confirm the income figure is real.
| What's in the Letter | What the Lender Checks Against It |
|---|---|
| Business income (verified by CPA) | Bank deposits and transaction history |
| Director / shareholder drawings | Personal bank account and lifestyle |
| Employment history and ABN duration | ABN lookup and business registration |
| Trading conditions (stable, declining, growing) | Comparison to prior year and forward outlook |
| Accountant qualifications (CPA/CA) | Professional register (ASIC / CA ANZ) |
The letter must be written by a qualified accountant — typically a CPA or Chartered Accountant. Some lenders accept tax agents, but most prefer the higher credential. The letter should be dated within the last three months and signed by the accountant (no templates from you).

What Lenders Actually Check — Four Keys
Lenders don't blindly accept the letter. They cross-check four critical areas to verify the income is sustainable and your serviceability is solid.
| Check | What Lenders Look For |
|---|---|
| Income Stability | Is income growing, flat, or declining? Manufacturers in tight margin zones (like now, with wages up 5.2% and sales growth at 4.2%) face tighter serviceability. Lenders scrutinize downtrends. |
| Bank Statement Match | Do deposits match the letter? Large discrepancies raise red flags. Lenders pull 3–6 months of statements to spot patterns. |
| Accountant Credibility | Is the accountant on the professional register? Lenders verify credentials and may contact the accountant directly. |
| Serviceability | Can you afford the loan repayment? With recent RBA rate hikes in early 2026, lenders are tightening servicing ratios and applying higher LVR caps. |
This is where manufacturing industry conditions matter. The RBA's consecutive rate hikes in early 2026 have tightened serviceability standards across the board. Manufacturers with declining margins are particularly affected. Your income statement needs to be strong enough to absorb both the rate environment and your borrowing costs.

Who One Doc Fits and Where It Stalls
One Doc is designed for manufacturers with a clear income profile: strong cash earnings, but tax returns that don't reflect that strength. It's not a magic fix — it still requires stable income, a qualified accountant, and solid manufacturing cashflow management.
One Doc stalls when:
- Your accountant won't sign the letter (or isn't qualified)
- Bank statements don't match the claimed income
- Income is declining or unstable
- ABN is under 2 years old
- Serviceability fails even at stated income
If One Doc doesn't fit, alternatives exist — equipment financing, working capital facilities, or even traditional full-doc if your tax returns are strong. Read more on managing cashflow pressure during tight margin periods.
Frequently Asked Questions
Not exactly — there's no mandated template — but the letter needs to include specific elements: your business income (verified from financial records), any director or shareholder drawings, employment history, ABN duration, and trading conditions (stable, growing, declining). The accountant must be a qualified CPA or Chartered Accountant, and the letter must be dated, signed, and on the accountant's letterhead. Some lenders have a preferred format; ask your broker for a template before your accountant writes it. This saves a rewrite.
Some accountants are uncomfortable with One Doc letters because they're wary of lender compliance or unsure of the format. Have a conversation first — ask if they're willing to provide a letter if you supply a lender template. If not, you may need to switch accountants or fall back to traditional full-doc lending. A broker can often convince a hesitant accountant by explaining lender requirements, or they can recommend an accountant who regularly provides these letters for manufacturers.
Very closely. Lenders pull 3–6 months of bank statements and look for deposits that align with the income figure in the letter. Minor variance is expected (timing differences, GST refunds, loans drawn), but large unrelated deposits or a pattern of deposits that don't match the letter will raise red flags. If your business income is significant, lenders expect to see consistent monthly deposits adding up to that figure, adjusted for seasonality in your manufacturing process.
Unlikely. Most lenders require a minimum 2-year trading history to assess income stability. If your ABN is newer, you may still apply for a full-doc home loan if you have solid tax returns (even one year can work with strong financials), or you could explore alternative lending such as equipment finance to build cashflow history. Talk to a broker about your options; some lenders are more flexible than others.
Not inherently, but it depends on the lender and your risk profile. Some lenders price One Doc the same as full-doc; others may apply a small premium due to reduced documentation. The bigger factor is your low-doc status and BAS history. If you have strong income, solid servicing, and good credit, most lenders will compete hard on rate regardless of whether you're One Doc or full-doc.
