Every Australian business registered for GST must submit a Business Activity Statement (BAS) to the Australian Taxation Office (ATO). For many small business owners, BAS time can be confusing, stressful, and time-consuming — especially without clear guidance or proper record-keeping.
At TSG Accountants, we believe your focus should stay on growing your business, not stressing about compliance. In this guide, we’ll walk you through the essential steps to manage BAS lodgement effectively while avoiding common mistakes.
What Is a Business Activity Statement (BAS)?
A Business Activity Statement is a form submitted to the ATO that reports your business tax obligations. It’s typically used to declare and pay:
- Goods and Services Tax (GST)
- Pay As You Go (PAYG) withholding
- PAYG instalments
- Other taxes (like fringe benefits tax instalments)
Businesses usually lodge BAS monthly, quarterly, or annually, depending on their turnover and reporting requirements.
When you partner with our Business Accounting specialists, we ensure your BAS lodgements are accurate, timely, and fully compliant.
Why BAS Lodgement Matters
Incorrect or late BAS submissions can result in ATO penalties and cash flow problems. Regular, accurate BAS lodgement gives you:
- A clear view of your business’s financial position
- Peace of mind regarding tax compliance
- Accurate data for decision-making and budgeting
If you’re unsure which reporting frequency applies to your business, our Business Structure team can help you choose the best setup for efficient tax management.
Step-by-Step BAS Lodgement Process
Here’s how to simplify BAS preparation and submission:
Step 1: Keep Accurate Records
All BAS figures are drawn from your bookkeeping records. Make sure your:
- Sales and purchase invoices are up to date
- GST on income and expenses is correctly recorded
- Bank reconciliations are current
A clean ledger is the foundation of accurate BAS reporting. Our Sole Trader Accounting experts can assist in maintaining reliable records all year round.
Step 2: Review Your GST Obligations
If your business earns over $75,000 annually, you must register for GST and include it in your BAS. Remember to check that:
- GST collected on sales matches your invoices
- GST paid on purchases is recorded for input tax credits
Your Business Accounting advisor can reconcile GST automatically through accounting software like Xero or MYOB to avoid errors.
Step 3: Report PAYG Withholding and Instalments
If you have employees, you’re required to withhold PAYG tax from wages and report it in your BAS.
PAYG instalments apply if you make regular payments toward your own income tax.
Getting this wrong can affect both your cash flow and ATO obligations. Our Individual Tax Services team ensures PAYG reporting aligns with your end-of-year tax requirements.
Step 4: Review and Finalise Before Lodging
Once your data is verified, calculate:
- Total GST collected (sales)
- GST paid (purchases)
- Net amount payable or refundable
- PAYG instalments (if applicable)
Always double-check calculations and ensure the correct ATO form is used. TSG Accountants offers a review service before each BAS lodgement, saving you time and reducing audit risk.
Step 5: Lodge and Pay
You can lodge BAS online via:
- The ATO Business Portal
- Registered tax or BAS agents
- Accounting software (e.g., Xero, MYOB)
If you use a registered BAS agent like TSG Accountants, you often receive extended due dates and support in case of ATO queries or corrections.
Common BAS Lodgement Mistakes to Avoid
Even experienced business owners can make errors that lead to penalties or unnecessary ATO attention. Here are the most common pitfalls:
- Misreporting GST-free or input-taxed sales
- Forgetting to claim eligible input tax credits
- Late lodgement and payment
- Using outdated or incomplete records
- Mixing personal and business expenses
A professional Business Accounting team ensures all these issues are avoided, so your compliance is always stress-free.
