A Business Activity Statement (BAS) is the form Australian businesses use to report and pay GST, PAYG withholding, PAYG instalments, FBT instalments, and other tax obligations to the ATO. If your business is registered for GST, lodging a BAS — monthly, quarterly, or annually — is mandatory. Getting it right protects your cash flow, keeps you off the ATO's radar, and turns every business purchase into a legitimate GST credit.
Avoid late-lodgement penalties, interest charges and ATO audit attention by lodging accurately and on time — every cycle.
Recover the GST paid on business purchases, equipment and expenses that would otherwise be lost to incorrect coding or missed deadlines.
A clean BAS cycle forces disciplined bookkeeping and gives you real-time insight into your GST and PAYG tax liabilities.
BAS lodgement is deceptively simple — until it isn't. These are the errors we see most often from DIY lodgers and that trigger ATO adjustments, penalties, and lost credits.
Treating GST-free items as taxable (or vice versa) leads to misreported GST. Food, medical services, education, exports and financial supplies all have specific GST treatment rules that trip up non-specialists.
If you pay employees — or contractors under a voluntary agreement or without an ABN — you must withhold tax and report it on your BAS. Forgetting this triggers ATO penalties and director liability exposure.
Businesses under $10M turnover can choose their GST reporting method, but switching mid-year or misunderstanding the timing rules causes reconciliation errors that compound each quarter.
The ATO charges Failure-to-Lodge penalties even if you owe nothing. Small businesses face $330+ per 28-day period overdue, up to five penalty units — on top of general interest on any unpaid tax.
Our BAS service is fully managed. We receive your Xero or MYOB file, review every transaction, reconcile your GST and PAYG positions, and lodge directly with the ATO through the Tax Agent Portal. Pair it with our bookkeeping service and you never have to think about BAS again.
Every BAS cycle we handle:
Your BAS frequency depends on your GST turnover. Lodging through a registered tax agent like Y&S Accounting also gives you an automatic extension on the standard due dates — one of the simplest wins of engaging a professional.
Required if your GST turnover is $20 million or more. The BAS is due on the 21st of the following month, and no tax-agent extension applies.
GST turnover ≥ $20MThe default for most small businesses with GST turnover under $20M. Due 28 days after the end of each quarter — 28 October, 28 February, 28 April and 28 July.
Most commonAvailable if you voluntarily registered for GST and your turnover is under $75,000. Lodged once a year alongside your income tax return.
Voluntary GST onlyLodging through a registered tax agent gives you an automatic four-week extension on each quarterly BAS due date — one of the easiest wins of engaging Y&S Accounting.
Included with our serviceYou must lodge a BAS if your business is registered for GST. GST registration is mandatory once your turnover exceeds $75,000 (or $150,000 for non-profits and $150,000 for taxi/ride-share drivers regardless of turnover). If you voluntarily registered for GST, you still need to lodge on the cycle the ATO assigned you.
The ATO charges a Failure-to-Lodge (FTL) penalty of one penalty unit ($330 as of 2025–26) for every 28 days overdue, capped at five units. General interest also accrues on any unpaid amounts. Lodging through a registered tax agent gives you an automatic extension and, in many cases, penalty remission if you have a good compliance history.
Yes — but most small business owners spend four to eight hours per quarter preparing a BAS and still miscode the tricky items. A registered BAS or tax agent typically pays for itself in recovered GST credits, avoided penalties and saved time. If you'd rather focus on running your business, engaging our bookkeeping and BAS service as a bundle removes the burden entirely.
Cash basis reports GST when money actually moves — you pay GST when customers pay you and claim credits when you pay suppliers. Accruals basis reports GST when invoices are issued, regardless of payment timing. Businesses with GST turnover under $10 million can choose; most small businesses use cash basis because it aligns tax with actual cash flow.
Yes. Even if you had zero sales and zero purchases, you must still lodge a nil BAS. Failing to do so triggers the same Failure-to-Lodge penalties as any other late lodgement. If your business is genuinely dormant, we can help you cancel your GST registration instead.
Yes. We can lodge revised BAS forms for up to four years in most cases, correct GST errors, and help you negotiate with the ATO if penalties have already been applied. This is often the first step when a new client comes to us mid-financial-year — and it's also where we tie BAS corrections into the annual business tax return.
Your BAS figures flow directly into your annual company, trust or sole trader tax return — so errors in your BAS become errors in your income tax return. Pair BAS with our tax planning service and we'll use your quarterly numbers to forecast year-end tax and reduce your liability legally before 30 June.
