Don't Get Caught Out by Late BAS

20 July 2026 · By Heaney Accounting

Running a busy trade business means your days are often spent on site rather than in the office. It is far too easy to let your BAS filing slip to the bottom of your to-do list while you focus on finishing a client's project. However, the Australian Taxation Office is strict when it comes to deadlines, and late lodgments often attract automatic penalties that eat directly into your hard-earned profits.

The best way to avoid this is to set aside a dedicated hour each month for bookkeeping. If you do not have the time to reconcile your accounts, consider outsourcing this task to a professional who understands the trade industry. By keeping your data up to date, you will not be scrambling at the last minute to find missing receipts when the quarterly deadline approaches.

Make sure you are setting aside your GST collected from customers in a separate high-interest account. Many tradies make the mistake of using this money to cover day-to-day business expenses like fuel or materials. If you treat the GST as money that belongs to the government from day one, you will always have the funds ready when your BAS is due.

Finally, stay proactive by checking your filing dates well in advance. If you are struggling with a difficult quarter, communicate with your accountant before the deadline passes rather than waiting until you are already in arrears. Taking control of your tax compliance early prevents the headache of debt recovery and lets you get back to what you do best: building and fixing.
