Yes. Most low doc and alt doc lenders require 24 months of continuous GST registration as proof of ongoing business activity. GST registration signals turnover above $75,000 per annum and is used alongside your ABN registration date to establish borrowing eligibility. Some specialist lenders accept 12 months in strong cases.
If you’re self-employed and GST registered, you have a significant advantage when applying for a home loan — one most borrowers don’t know about.

Most people assume that GST registration is purely an ATO tax obligation. But for self-employed Australians applying for a low doc home loan, it’s also a powerful piece of income evidence that specialist lenders take seriously.
Here’s exactly what GST registration means for your home loan application — and why it works in your favour.
You must register for GST once your business turnover exceeds $75,000 per year. That means GST registration is an ATO-verified signal that your business earns above this threshold.
For a lender assessing a self-employed borrower, this matters for two reasons:
Standard home loans require two years of personal tax returns to prove income. For self-employed borrowers, this is often the problem — tax returns show taxable income after deductions, which is frequently much lower than actual cash flow.
Low doc home loans work differently. Instead of tax returns, specialist lenders accept:
Because your BAS statements are lodged directly with the ATO, they carry real weight. A lender can see your actual business turnover — the number before you’ve claimed every possible deduction — and assess your true capacity to repay a loan.
When a specialist lender reviews your BAS statements, they’re looking at:
They annualise your turnover (adding up 12 months of BAS totals) and use that figure — adjusted for estimated business expenses — to calculate your borrowing capacity. This is a fundamentally different calculation from what a major bank does with your tax return, and for most self-employed borrowers it produces a significantly higher result.
No — but it does limit your options. If your turnover is below $75,000 and you’re not GST registered, you still have access to low doc lending, but lenders will rely more heavily on business bank statements and an accountant’s declaration rather than BAS statements.
GST registration simply gives lenders more confidence and more documentation to work with. It’s an advantage, not a requirement.
Lenders want to see that your business is established, not a recent setup. Most specialist low doc lenders require at least 24 months of ABN registration — two full years of trading — before they’ll lend based on BAS statements alone.
If you have 24 months ABN and GST registration, you sit in the strongest possible position for a low doc home loan application:
Consider a self-employed plumber — sole trader, 3 years ABN, GST registered. His tax return shows $58,000 taxable income after deductions. His BAS statements show $280,000 in annual turnover.
At a major bank, he gets assessed on $58,000. The bank says no.
At a specialist lender via Outlook Finance, he gets assessed on $280,000 turnover. After applying standard expense ratios for his industry, his assessed income is approximately $140,000–$168,000. He qualifies for a loan of up to $850,000 — on the same income, with the same business.
The difference isn’t his income. It’s the documentation — and who looks at it.
If you’re GST registered, have 24 months ABN, and want to buy or refinance a property, you likely have more borrowing capacity than you think. The key is finding the right lender — one who knows how to read BAS statements and assess self-employed income properly.
