BAS: Business Activity Statement
The Australian Taxation Office (ATO) issues a form called the Business Activity Statement (BAS). It enables companies to fulfill their tax reporting and payment obligations.
BAS consists of luxury car tax (LCT), fuel tax credits (FTC), wine equalization tax (WET), PAYG withholding, PAYG installments, GST, and fringe benefits tax (FBT) instalments.
It is very important to understand what your form contains because the BAS covers a variety of tax forms. You have to lodge your BAS accurately and on time – through a tax agent or the Australian Tax Office’s online service.
Otherwise, you could face heavy penalties!
Lodge Your Business Activity Statement: How To Submit?
The Australian tax office offers the following options for BAS lodgement.
- ATO Online Services for Business: It is the online and preferred method for several businesses because it is more convenient and faster.
- Through a tax or BAS Agent: Your agent must be registered, though it is best for your business if you outsource tax.
- Standard Business Reporting: If you use accounting software that supports SBR.
- MyGov: MyGov profile is only for solo traders; they can lodge by using their profile.
- By Phone: It is for the times when you have nothing to report; only then can you lodge by phone.
- By Mail: You can utilize the paper form that the ATO supplied you.
To let you know when to file, the ATO usually provides the BAS two weeks before the end of your reporting period. Being prepared in advance helps prevent last-minute stress and errors.
Reporting Cycles & Due Dates
The Australian Tax Office sends a form for each reporting period; your due date is printed on the business activity statement form. The common reporting cycles of lodgement are:
- Monthly: Businesses that secure a GST turnover of $20 million or more $20 million are obliged to report monthly.
- Quarterly: It applies to start-ups or mainly small businesses.
- Annually: It is for companies with annual revenue under $75,000 that voluntarily registered for GST.
Delayed lodgement or payments can lead to penalties, so if you sense any delay in the process, inform the ATO before the due date, as it would save your energy and money.
Get Your BAS Right
The mistakes in your business activity statement can cause you serious trouble. The correct statement saves you from heavy penalties and portrays you as a responsible businessman.
Cross-check your accounting records with your BAS figures:
Make sure your numbers are on point and match your bank statements, invoices, and purchase receipts.
Cross-check your purchase and sale timings:
The most common mistakes occur in timings, so you must check that sale and purchase transactions are within the period covered by BAS.
Sections of Business Activity Statement Form:
You have to complete and report only those sections that apply to your business.
Use Accurate Labels for Each Tax Type on the Form:

- FBT uses labels F1–F4, 6A, 6B
- LCT uses labels 1E, 1F
