Mastering Your Quarterly BAS Submission

27 July 2026 · 6 min read · By Heaney Accounting

Filing your Business Activity Statement (BAS) shouldn't be a nightmare. By keeping your records in order throughout the quarter, you can breeze through the submission process without last-minute stress.

Essential Preparation Steps

  1. Reconcile your bank feeds at the end of every month.
  2. Ensure all purchase invoices have GST components clearly marked.
  3. Check that your payroll tax and superannuation figures match your accounting software.
  4. Run a draft BAS report to identify any discrepancies before the due date.

Pro Tip: Always set aside your GST collected in a separate high-interest savings account. It’s not your money, and having it ready to pay ensures you never miss a deadline.

Consistency is key. If you leave everything to the week before the deadline, you are more likely to make mistakes that lead to ATO audits or late penalties.
