Do bank‑statement and BAS‑based loans have lower maximum LVRs?

Often they do. Many lenders cap alt‑doc loans at lower LVRs than full‑doc loans to manage risk, especially above 80% where lenders mortgage insurance may apply. Exact limits vary by lender, product and your overall risk profile, so it’s important to check policy before you commit to a purchase or refinance.

Key Takeaway

This article explains that the choice between bank statement and BAS-based home loans for self-employed Australians depends on whether recent bank inflows or BAS figures best show stable, serviceable income. Bank-statement loans typically rely on 6–12 months’ business account credits, while BAS-based loans use 2–4 recent BAS quarters and assumed expense ratios. With mortgage stress affecting around 32.5% of borrowers, choosing the structure that aligns with real, sustainable cashflow and planning to refinance to full-doc later can materially reduce long-term risk and interest costs.

Bank statement vs BAS‑based home loans comes down to a simple rule: choose the method that best shows stable, realistic income without over‑stretching your cashflow or tax position. Bank‑statement loans lean on recent money flowing through your accounts. BAS‑based loans lean on your lodged BAS and implied turnover. Both are alt‑doc options for self‑employed borrowers whose tax returns don’t tell the full story.

In today’s tight lending environment (with APRA’s 3% buffer and rising mortgage stress), getting this choice wrong can cost you years of higher interest and extra risk.

1. Quick definitions: bank statement vs BAS‑based income

What is a bank‑statement home loan?

A bank‑statement home loan is an alt‑doc loan where the lender assesses your income using 6–12 months of bank statements instead of (or as well as) full financials.

They total eligible business credits, apply an income factor (for example, 40–70% of gross deposits), and treat that as your income for serviceability.

What is a BAS‑based home loan?

A BAS‑based home loan uses your Business Activity Statements (usually the last 2–4 quarters) to estimate turnover and net income.

Lenders start with your reported sales, then apply industry‑standard expense ratios or your actual expenses to derive an income figure.

Both options generally sit in the “low‑doc/alt‑doc” bucket, with higher rates and tighter LVRs than sharp full‑doc loans. For typical pricing differences, see /insights/interest-rates-fees-self-employed-low-doc-vs-full-doc.

2. Side‑by‑side: which suits which kind of business?

Here’s a practical comparison to anchor the decision.

Feature / Question	Bank‑statement home loan	BAS‑based home loan
Core documents used	6–12 months business (sometimes personal) bank statements	2–4 most recent BAS lodged with ATO
Best when…	Recent cashflow is strong and consistent	BAS shows stable or growing turnover and reasonable profit
Sensitive to tax planning?	Less – focuses on actual deposits	More – aggressive deductions can reduce inferred income
Time period emphasised	Recent 6–12 months	Last 6–12 months, but by quarters
Who it usually suits	Contractors, tradies, online businesses, seasonal with upswing	Established businesses with clean BAS and bookkeeping
Typical weaknesses	Large one‑offs, transfers, and refunds may be excluded	Irregular lodgements, ATO debt, low margins cause issues
Rate / fee level (indicative only)	Slightly higher or similar to BAS‑based alt‑doc	Similar to bank‑statement alt‑doc
Documentation discipline required	Moderate – clean statements, no chaos	Higher – on‑time BAS, reconciled accounts

3. How lenders actually crunch the numbers

Bank‑statement method: what they like and dislike Lenders download your statements and categorise credits: 1. Include: customer invoices, POS settlements, online sales, recurring contract income. 2. Exclude: transfers between your own accounts, loan proceeds, tax refunds, “round‑trip” shuffling. Then they apply an income factor (say 60%) to allow for expenses. Worked example – bank‑statement income - Business credits over 12 months: $360,000 (average $30,000 per month). - Lender income factor: 60%. - Assessed annual income: $360,000 × 60% = $216,000. - Monthly assessed income: $18,000. On that figure, many…

Frequently asked questions

Neither is automatically better; the right choice depends on where your numbers are strongest. If your bank accounts show steady recent cash inflows and fewer red flags, a bank‑statement loan can work best. If your BAS are clean, timely and show strong turnover and margins, BAS‑based may give clearer borrowing capacity.

Some lenders still ask for recent tax returns as a sense‑check, but they primarily rely on bank statements or BAS for the income figure. Others are more flexible, especially if you can show 6–12 months of strong deposits or multiple BAS quarters. A broker will match you to a lender whose documentation rules fit your situation.

The loan itself doesn’t change past BAS, but your ongoing tax planning should stay consistent with the income story shown to the lender. If we present higher sustainable income to support a loan, you may choose to declare more profit in future years, which can increase tax. Coordinating with your tax adviser is essential.

Yes, most borrowers use alt‑doc loans as a stepping stone until their financials catch up. Once you have one or two years of strong tax returns and clean accounts, you can usually refinance to full‑doc at sharper rates. Planning this shift early can save substantial interest over the life of the loan.
