Quick answer
You can still get a low doc business loan with only one or two BAS lodged, but your options are narrower. Many low doc lenders prefer several quarters of BAS, so with fewer they lean harder on business bank statements, how long the ABN has traded, an accountant's letter and any property security. A business that recently crossed the $75,000 GST threshold often has a longer trading story than its BAS shows.
Key points
- GST registration is required within 21 days once GST turnover reaches $75,000.
- Many low doc lenders prefer several quarters of lodged BAS; one or two narrows the field.
- Bank statements covering the period before GST registration can show the longer trading story.
- An accountant's letter can bridge the gap between registration and a full year of BAS.
- Property security makes a short BAS history matter much less.
Yes, but with fewer lenders to choose from. Low doc lending usually leans on several quarters of lodged BAS. With only one or two, lenders shift their attention to your business bank statements, how long the ABN has been trading, an accountant’s letter and any property you can offer. A business that has only just crossed the GST threshold often has a much longer story than its BAS shows.
That’s the key point for most readers of this guide. Your BAS history may be short because you only recently registered for GST, not because you only recently started. Showing a lender the difference is most of the job.
Why does a short BAS history matter to a low doc lender?
Low doc lending replaces up-to-date tax returns and full financial statements with lighter evidence. The most common substitute is lodged BAS, because it’s a regular, ATO-lodged record of sales. Our page on low doc business loans explains the full set of alternatives.
Quarterly BAS gives a lender a picture of turnover every three months. With several quarters, they can see trends, seasonality and whether sales are steady. With one or two, they can’t tell whether a strong quarter is normal or a spike. That uncertainty is what narrows your options, not the short history itself.
Why might a well-established business have only one or two BAS?
More often than you’d think. Common reasons include:
- Crossing the GST threshold. The ATO requires you to register for GST once GST turnover reaches $75,000, and you must do so within 21 days. A business that traded for years below that line will have no BAS history from that period.
- Moving from annual to quarterly reporting. Some voluntarily registered businesses under the threshold lodge an annual GST return. Once they grow past $75,000, they move to regular BAS.
- A change of structure. Moving from sole trader to a company or trust usually means a new ABN and a fresh BAS history, even though the business itself is the same.
- A late start on lodgements. Some owners register but fall behind, then catch up all at once.
In each case, the business may have a solid trading record. It just isn’t in BAS form yet.
What can fill the gap?
Think of it as building a bridge from the business’s real history to the few BAS you have.
| Evidence | What it shows the lender |
|---|---|
| Your one or two lodged BAS | Current turnover since GST registration |
| Business bank statements, ideally 6 to 12 months or more | Actual deposits, including the period before registration |
| ABN registration history | How long you’ve actually been trading |
| Accountant’s letter | Confirms turnover, structure and that lodgements are current |
| Invoices or contracts | Shows where future revenue is coming from |
| Property details, if any | Security that reduces reliance on trading history |
Bank statements carry the most weight. Statements covering the months before GST registration show the growth that pushed you over the threshold. That turns “only one BAS” into “a steadily growing business that recently registered for GST”.
An accountant’s letter fills context. A short letter confirming turnover for the past year, the reason for the short BAS history and that the business is up to date with its obligations helps a lot.
If you’re not sure whether what you have is enough, send a quick enquiry and let a real person look at it before you chase more paperwork.
How does timing affect your application?
BAS has to be lodged before a lender can use it. Quarterly BAS is due 28 October, 28 February, 28 April and 28 July, with extra time often available when lodging online or through an agent. Voluntarily registered businesses under the threshold that lodge annually have a 31 October due date for their annual GST return.
If you’re a few weeks from the end of a quarter and don’t need funds urgently, waiting to lodge one more BAS can widen your options. If the need is now, don’t wait: apply with what you have and let the bank statements do more of the work.
A practical tip: lodge promptly, but accurately. A rushed BAS that needs amending later creates more questions than a short history ever would.
It also pays to look at your BAS the way a lender will. Does the sales figure line up with the deposits in your bank statements for the same quarter, allowing for timing? If you’re on the cash basis, the two should sit fairly close. If you’re on the non-cash basis, invoices raised late in the quarter may not be in the bank yet, and a one-line note explaining that saves a question. Lenders working from only one or two BAS lean on that match even more heavily than usual, because they have so little else to cross-check.
Finally, keep the first quarter in perspective. A first BAS after registration sometimes covers only part of a quarter, or includes a burst of equipment purchases with GST credits that make the net position look unusual. Point that out up front rather than leaving the lender to puzzle over it.
Which loans suit a short BAS history?
Unsecured and cash-flow loans. These typically run from $5k to $500k, sized on turnover and bank statements. With a short BAS history, expect a more conservative amount at first. A lender who sees strong statements may still lend comfortably; one who relies mainly on BAS may want to wait. See unsecured business loans.
Property-secured loans. Once there’s property behind the deal, the number of BAS on file matters far less. Property-backed business lending runs from $20k up to $5m, using first or second mortgages or a caveat. Owners borrowing against the family home can read how that’s structured on our home equity business loans page.
New business loans. If your business genuinely is new, rather than newly registered, new business loans covers how lenders approach start-ups.
Whichever route, the general documents still apply. The official checklist on applying for a business loan lists proof of identity, financial reports where available, forecasts and personal financial information.
What does this look like in practice?
Illustrative example only. A café owner traded as a small coffee cart for three years, well below the GST threshold. After moving into a shopfront, turnover climbed quickly and she registered for GST. Six months later, she has two BAS lodged and wants $60k for a second espresso machine, a display fridge and a bigger fit-out at the counter.
Her first lender declines because it wants four quarters. She tries again with twelve months of bank statements showing the cart income and the jump after the move, her ABN record showing three years of trading, the two BAS, and a short letter from her accountant explaining the timing.
A low doc lender sees a three-year business that recently grew past the threshold, not a six-month start-up, and offers an unsecured loan sized on her bank statements. Our business loan for a café page covers how lenders read cafés more broadly.
Short BAS history, longer story? Let’s tell it properly
A short run of BAS doesn’t mean a short-lived business. If you’ve been trading for a while and only recently crossed into GST, you’ve got more to show a lender than you might think.
Our enquiry takes about a minute, and there’s no credit check when you first enquire. We won’t hand your details to a pile of lenders, so you won’t be swamped by calls. A real person reads what you send, including how long you’ve really been trading, and phones you to talk through what fits. Please fill it in accurately, especially when you started and when you registered for GST, so we can match the right option first time.
Frequently asked questions
How many BAS do I need for a low doc business loan?
It varies by lender. Many like to see a few quarters, often two to four. With only one or two lodged, some unsecured lenders will still proceed if bank statements are strong, and property-secured lenders focus more on the security than the BAS count.
I only registered for GST recently. Does that mean my business is new?
Not necessarily. Many businesses trade for years below the $75,000 GST threshold before registering. Your ABN history and bank statements can show that longer track record even when your BAS history is short.
Can I use bank statements from before I registered for GST?
Yes, and you should. Statements from before registration show how the business has grown and help a lender see that your first BAS reflects an established operation rather than a brand-new one.
I'm voluntarily registered and lodge GST annually. Does that count?
An annual GST return is still evidence, but it gives a lender one snapshot a year rather than quarterly detail. Expect more reliance on bank statements and an accountant's letter.
Should I lodge my BAS early to help a loan application?
Lodging promptly after the quarter ends is sensible, because lenders can only use lodged BAS. Make sure it's accurate rather than rushed; a BAS that has to be amended later creates more questions than it answers.
What loan amounts are possible with a short BAS history?
Unsecured and cash-flow options typically run from $5k to $500k and are sized on turnover and bank statements, so a short history usually means a more modest unsecured amount. Property-secured loans range from $20k to $5m.
