Quick Answer
SAB Autopilot tracks GST on every invoice you create and calculates your BAS position automatically. At any time you can ask 'What is my GST position this quarter?' and get an immediate answer. At quarter end, it generates a BAS summary PDF you can review, approve, and email to your accountant — all from one chat window.
For most Australian small business owners, BAS time is the most stressful quarter of the year. You spend hours pulling invoices together, checking GST totals, reconciling bank statements, and hoping the numbers add up before the ATO deadline.
SAB Autopilot changes this entirely. Because every invoice you create through the platform is GST-coded at the point of creation, your BAS position is always current — not something you calculate once every three months in a panic.
This guide explains exactly how SAB Autopilot handles GST tracking and BAS preparation, what it can and cannot do, and how it fits into your existing tax obligations as an Australian small business owner.
Every invoice created through SAB Autopilot is automatically coded for GST at the time of creation. When you tell the AI 'Create an invoice for $1,100 for web design services', it builds the invoice with $100 GST (10%) separated out and records both the GST-exclusive amount and the GST component in your account.
This means your GST liability is calculated continuously, not at the end of the quarter. At any point you can ask: 'What is my GST position for this quarter?' and receive an immediate breakdown: total sales (GST-inclusive), total GST collected, and your net GST payable.
For purchases where you are claiming GST credits, you enter them through the AI chat in the same way: 'Record a $550 expense for office supplies from Officeworks.' The system records the GST credit against your liability, reducing what you owe the ATO.
When the end of a BAS quarter arrives (March, June, September, December), you do not need to log into a separate system or open a spreadsheet. You simply ask SAB Chat: 'Prepare my BAS for this quarter.'
The system pulls together: - Total GST collected on sales (G1 and 1A) - Total GST credits on purchases (G10 and 1B) - Net GST payable or refundable - PAYG withholding if you have employees (W1 and W2)
It presents this as a BAS summary card in the chat, shows you the figures, and asks if you want a PDF. You approve, and it generates a formatted BAS summary PDF you can email directly to your accountant or use as a reference when lodging online through myGov Business.
Important: SAB Autopilot prepares the BAS summary — a registered BAS agent or tax agent must lodge it with the ATO on your behalf, or you can lodge it yourself through the ATO's Business Portal. The AI cannot lodge directly.
SAB Autopilot sends automatic BAS reminders at 28 days and 7 days before each quarterly deadline. The 2026 quarterly BAS due dates are:
- Q1 (Jul–Sep 2026): 28 October 2026 - Q2 (Oct–Dec 2026): 28 February 2027 - Q3 (Jan–Mar 2027): 28 April 2027 - Q4 (Apr–Jun 2027): 28 July 2027
Businesses registered with a tax agent receive an extended deadline. If you use a BAS agent, you may have until the following month.
The reminders come via email and are also surfaced in SAB Chat when you log in near the deadline period. This eliminates the most common cause of BAS penalties: forgetting the deadline.
GST has edge cases that the AI handles with caution rather than guessing. Specifically:
- Mixed-use assets (partly private, partly business) require manual apportionment. The AI will flag these when you record them and ask for the business-use percentage. - Input-taxed supplies (financial services, residential rent) are not subject to GST, and the AI requires you to specify the supply type when recording them. - Capital acquisitions with complex cost base adjustments (e.g., vehicles over the luxury car threshold) are flagged for accountant review. - GST on imported services (reverse charge) is noted but not automatically calculated — the AI flags these transactions for manual review.
For straightforward small businesses — invoicing for services, buying office supplies, paying wages — SAB Autopilot handles 95% of the GST workflow automatically.

Start free trialNo. SAB Autopilot prepares the BAS summary with all figures calculated — but lodgement must be done by you through the ATO Business Portal (myGov), or by your registered BAS agent or tax agent. The AI generates the summary and PDF; you or your agent submit it.
The standard Australian GST rate of 10%. All invoices created through the platform apply 10% GST unless you specify that the supply is GST-free (like exports or basic food) or input-taxed.
You can record all business purchases, but the AI flags purchases where GST credits may not apply — such as wages (no GST), ASIC fees (no GST), and some insurance products. It asks for clarification before treating ambiguous purchases as creditable.
No. You can use SAB Autopilot for invoicing and payroll without being GST-registered. If you are under the $75,000 turnover threshold and not registered, invoices are created without GST. The system asks for your GST status during setup.
