If you’re a small business owner in Australia, you’ve probably heard of BAS due dates, but do you really understand what they mean for your business? Don’t worry — you’re not alone. Many entrepreneurs struggle with Business Activity Statements (BAS), deadlines, and the rules around it.
In this guide, we’ll break down what BAS is, when it’s due, how a registered tax agent can help, and why working with a trusted professional like Perfect Accounting PTY Ltd can be one of the smartest financial moves you make.
What is BAS?
BAS (Business Activity Statement) is a form submitted to the ATO (Australian Taxation Office) to report and pay certain taxes. These include:
-
Goods and Services Tax (GST)
-
Pay As You Go (PAYG) withholding
-
PAYG instalments
-
Fringe Benefits Tax (FBT)
-
Fuel tax credits
Basically, BAS helps the government collect tax in a timely and efficient manner. It’s usually lodged either monthly or quarterly, depending on your business size and ATO requirements.
️ What Are the BAS Due Dates?
One of the most confusing parts of BAS is remembering when it’s due. Let’s break it down.
Quarterly BAS Due Dates (Standard)
| Quarter | Period Covered | Due Date |
|---|---|---|
| Q1 | July – September | 28 October |
| Q2 | October – December | 28 February |
| Q3 | January – March | 28 April |
| Q4 | April – June | 28 July |
Bonus: If you use a registered tax agent like Perfect Accounting, you may get a 4-week extension on these due dates!
