Understanding Your BAS: What Bookkeepers Wish You Knew

If you’re a small business owner in Australia, chances are you’ve heard of the Business Activity Statement (BAS). But for many, BAS lodgement remains a source of confusion, stress, and last-minute scrambling. At Bentleys, our bookkeepers work with hundreds of clients to simplify this process—and we’ve learned a few things we think every business owner should know.

What is a BAS, and why does it matter

A BAS is a form submitted to the Australian Taxation Office (ATO) to report and pay taxes, such as:

• Goods and Services Tax (GST)
• Pay As You Go (PAYG) withholding
• PAYG instalments
• Other tax obligations

These are typically lodged monthly or quarterly, depending on your business size and structure. Accurate BAS reporting is not just a compliance requirement—it’s a reflection of your business’s financial health.

What bookkeepers wish you knew

1. BAS is a shared responsibility

While your BAS agent is legally responsible for lodging your statement correctly, the accuracy of your BAS depends on the quality of the information provided. That means:

• • Keeping receipts and invoices organised
  • Ensuring payroll records are complete
  • Communicating clearly with your bookkeeper about business changes 

2. Timeliness is everything

Submitting your BAS on time is critical—not just for compliance, but for maintaining a smooth financial workflow. Late lodgements can lead to penalties, interest charges, and unwanted attention from the ATO. More importantly, delays often stem from incomplete documentation or slow responses to queries from bookkeepers.

When your bookkeeper requests clarification or supporting documents, responding promptly helps avoid bottlenecks and ensures your BAS is lodged accurately and on time. Timely communication and record-keeping are essential for maintaining a compliant and stress-free business.

3. Your bookkeeper is your financial guide, not just a data entry clerk

Bookkeepers at Bentleys are trained to interpret financial data, flag compliance risks, and advise on GST treatments. They’re also responsible for:

• • Applying correct tax codes
  • Reconciling bank feeds
  • Preparing audit-ready documentation 

How to make BAS easier

Here are practical steps to simplify your BAS process:

• Utilise accounting software – Tools such as Xero, MYOB, or QuickBooks automate GST calculations and generate BAS reports. Bentleys offers training sessions to help clients use these platforms effectively 
• Schedule check-ins – spend 30 minutes each week updating your records. This habit reduces last-minute stress and improves accuracy 
• Respond to bookkeeper queries promptly – if your bookkeeper requests clarification or documents, respond promptly. Delays can cause your BAS to be placed in “awaiting review” status, slowing down the entire process.
• Understand your obligations – understanding your obligations is key to maintaining a financially resilient business. You must maintain truthful records, submit accurate data, and lodge on time. Your BAS agent is legally bound to act in your best interest—but they need your cooperation to do so. This understanding empowers you to take control of your business’s financial health.
