Staying on top of tax deadlines is essential for businesses in Australia to avoid penalties and maintain good standing with the Australian Taxation Office (ATO). From lodging BAS and GST to PAYG withholding and income tax returns, missing a deadline can create unnecessary stress and financial strain. This guide will help you understand the key dates every business should know and how to stay compliant.

1. Business Activity Statements (BAS)

Businesses registered for GST must lodge a Business Activity Statement (BAS) regularly. The frequency—monthly, quarterly or annually—depends on your GST turnover and ATO requirements.

Key dates for BAS lodgements:

  • Monthly BAS: Due on the 21st of the following month (e.g., January BAS is due on 21 February).

  • Quarterly BAS: Due on the 28th of the month following the quarter (e.g., Q1 ending 31 March is due on 28 April).

  • Annual BAS: Typically due on 31 October with your income tax return.

Timely BAS lodgements are crucial for reporting and paying GST, PAYG withholding and other taxes.

2. Goods and Services Tax (GST)

If your business is registered for GST, you must report and pay GST as part of your BAS lodgements. The same deadlines apply as those for BAS, whether you lodge monthly, quarterly or annually.

Ensure you have accurate records of sales and purchases to calculate your GST obligations correctly.

3. Pay As You Go (PAYG) Withholding

If your business employs staff, you’re responsible for withholding PAYG tax from wages and remitting it to the ATO. PAYG withholding is typically reported as part of your BAS.

Key dates for PAYG withholding:

  • Monthly PAYG withholding: Due on the 21st of the following month.

  • Quarterly PAYG withholding: Due on the same dates as quarterly BAS lodgements.

Accurate payroll records and timely reporting are critical to ensure compliance.

4. Income Tax Returns

All businesses must lodge an annual income tax return to report their earnings and calculate tax obligations.

Key dates for income tax returns:

  • Sole traders and small businesses: Due on 31 October unless you use a registered tax agent, which may extend the deadline.

  • Larger businesses: Due dates vary depending on the ATO’s requirements and your tax agent’s lodgement program.

Preparing your financial statements well in advance can help ensure an accurate and timely submission.

5. Superannuation Guarantee Contributions

If you employ staff, you’re required to pay superannuation contributions to their nominated super funds by the quarterly due dates.

Key superannuation deadlines:

  • Quarterly payments: Due on 28 January, 28 April, 28 July and 28 October.

Late payments may incur interest and penalties, so it’s essential to meet these deadlines.

6. Fringe Benefits Tax (FBT)

If your business provides fringe benefits to employees, such as company cars or entertainment, you may need to lodge a Fringe Benefits Tax return.

Key FBT dates:

  • FBT year-end: 31 March.

  • FBT return lodgement: Due on 21 May, or later if using a tax agent.

Understanding your FBT obligations can prevent unexpected liabilities.
