Your ATO BAS Proves Your True Cash Flow. Use It to Get Approved in 48 Hours
Every Australian business owner knows the quarterly ritual of preparing Business Activity Statements (BAS). Your BAS statement represents verified, statutory truth submitted directly to the ATO: exact gross sales (Box G1), GST collected, and export sales. It reflects what your trade business is earning right now—not what happened 18 months ago.
Yet standard retail bank branches refuse to look at BAS statements in isolation. They demand full company financials, balance sheets, and depreciation schedules that take months for accountants to compile.
Wholesale non-bank lenders use a streamlined 6-Month BAS calculation model. By analyzing your last 2 consecutive quarterly BAS returns, underwriters calculate your annualized turnover and apply established trade expense margins to determine your borrowing capacity in under 48 hours.
Here is our strategy: We ask you a few quick questions about your situation, then match you directly with an accredited specialist who will fight for your approval, cut through bank red tape, and deliver your loan with zero stress. Get matched directly with an accredited specialist in 60 seconds via the Mortgage Matcher.

1. How Non-Banks Calculate 6-Month BAS Servicing Income
The underwriting formula for a 6-Month BAS mortgage is completely standardized across top-tier non-bank lenders:
Formula: (Quarter 1 G1 + Quarter 2 G1) × 2 = Annualized Gross Turnover. The underwriter then multiplies this figure by your trade's net profit margin (typically 40% to 60% depending on whether you employ staff or work as a solo subcontractor).
2. Documentation Required for 6-Month BAS Pre-Approval
To secure a 48-hour formal pre-approval under a 6-Month BAS policy, you only need four documents:
- Last 2 Quarters of Lodged BAS: Sourced directly from your myGov or ATO Business Portal showing Box G1 (Total Sales).
- ATO Client Communication Statement / Portal Summary: Confirming your BAS statements were received and lodged.
- 6 Months Business Bank Statements: Proving that cash deposits match or exceed the gross sales reported on your BAS.
- Current Driver Licence & ID: Standard 100-point identity check.
3. Combining BAS with 10% Deposits and Up to 90% LVR
While standard low-doc policies cap at 80% LVR, select wholesale non-bank desks approve 6-Month BAS applications up to 85% to 90% LVR with specialized risk assessment.
This allows tradies to buy property with just a 10% to 15% deposit plus stamp duty, keeping substantial liquid capital inside their trade operating accounts.
