GST and BAS are two of the most Googled topics by Australian small business owners and two of the most confusing. What is a BAS? Do you even need to lodge one? What goes where? What happens if you're late?
This guide answers all of it. In plain English. Without assuming you already know what G1, 1A, or 1B mean.
The Nuffy's Guide: GST & BAS Prep Guide is a 24-page guide written specifically for Australian sole traders, freelancers, contractors, and small business owners who are registered for GST, or thinking about registering, and want to actually understand what they're doing, rather than just guess and hope for the best.
What's inside:
✓ What GST is (taxable sales, GST-free, and input-taxed explained clearly)
✓ Do you need to register? (the $75,000 threshold, voluntary registration, pros and cons)
✓ What a BAS is and what actually goes on it (G1, 1A, 1B, PAYG explained in plain English)
✓ How often you lodge (quarterly, monthly, and annual cycles compared)
✓ Quarterly BAS due dates (including the online lodgement bonus)
✓ How to calculate your GST
✓ How to lodge (myGov, SBR software, BAS agent, or mail)
✓ What happens if you lodge or pay late (FTL penalties and GIC explained, including the 2025 change making GIC non-deductible)
✓ Records you need to keep and for how long
✓ Cash vs accrual accounting for GST and why it matters
✓ 7 ATO-backed transaction classification tables (what goes where on your BAS, sourced directly from the ATO's Simpler BAS GST Bookkeeping Guide)
✓ Common mistakes to avoid
✓ BONUS: 10-point BAS lodgement checklist to tick off before you submit every quarter
What makes this guide different:
Most GST guides explain the concept and stop there. This one goes further. The transaction classification tables alone tell you exactly where each type of sale or purchase goes on your BAS, from utility bills and motor vehicle registration to imports and mixed-use purchases. It's the practical reference most guides skip entirely.
Who this is for:
Sole traders, freelancers, and small business owners who are registered for GST (or about to register), preparing their own BAS, or wanting to understand what their accountant or BAS agent is actually doing on their behalf.
Format: Instant PDF download, 24 pages, print-friendly. Includes bonus BAS lodgement checklist.
Please note: This guide is general information only, not legal, tax, or financial advice. Always confirm details with the ATO (ato.gov.au), a registered tax agent, or BAS agent before acting on anything in this guide. Guide current as at July 2026.
