If your business is registered for GST, managing your Business Activity Statement (BAS) is a key part of staying compliant with the Australian Taxation Office (ATO). BAS lodgements summarise your tax obligations, such as GST, PAYG instalments, and more. Knowing your BAS due dates and how to manage lodgements can help you avoid unnecessary penalties and keep your business running smoothly.

What is a Business Activity Statement (BAS)?

A BAS is a form issued by the ATO that businesses registered for GST must lodge regularly. It provides a summary of your tax obligations, including:

  • Goods and Services Tax (GST)
  • Pay As You Go (PAYG) withholding tax
  • PAYG instalments
  • Fringe Benefits Tax (FBT) instalments
  • Fuel tax credits
  • Other taxes relevant to your business

The information in your BAS determines whether you owe the ATO or are entitled to a refund.

BAS Due Dates: Monthly, Quarterly, and Annual

Monthly BAS Due Dates

Businesses with an annual turnover of more than $20 million must lodge their BAS monthly. The due date is the 21st of the following month. For example, the BAS for October is due on 21 November.

Quarterly BAS Due Dates

If your business turnover is less than $20 million, you will likely lodge your BAS quarterly. The deadlines are:

  • Quarter 1 (July to September): 28 October
  • Quarter 2 (October to December): 28 February
  • Quarter 3 (January to March): 28 April
  • Quarter 4 (April to June): 28 July

Annual BAS Due Dates

Smaller businesses with a turnover below $75,000 (or $150,000 for non-profits) may opt for annual BAS lodgement. In this case, the BAS is due along with your income tax return.

How to Turn Around a Business That’s Losing Money..

Just because your business is losing money doesn’t mean you’ve failed — it just means there’s room for a smarter approach. Get accounting tips and insights to help you turn things around for good.

How to Lodge Your BAS

There are several ways to lodge your BAS:

  1. Online: Sole traders can use their myGov account linked to the ATO, while businesses may use ATO Online services or SBR-enabled software.
  2. Through a Tax or BAS Agent: Registered agents can handle your BAS lodgement, ensuring accuracy and compliance.
  3. By Mail: Use the pre-addressed envelope included in your BAS package to send your completed form.

Lodging on time is critical, even if you’re unable to pay the amount owed. Late lodgements can attract penalties, so always prioritise meeting the deadlines.

How to Pay Your BAS

Payments can be made using BPAY, a credit card, or a direct debit from your bank account. You’ll need your Payment Reference Number (PRN) to ensure the payment is credited correctly.

If you’re unable to pay in full by the due date, it’s better to lodge your BAS on time and arrange a payment plan with the ATO. Interest charges may apply, but staying on top of lodgements helps avoid additional penalties.

Common BAS Questions

What if I need a refund?
BAS refunds usually take 7–14 business days to process. Delays may occur if your lodgements aren’t up to date, your bank details are incorrect, or you owe money to the ATO.

Do sole traders need to lodge BAS?
Yes, if your turnover exceeds $75,000 annually. Sole traders earning below this threshold are not required to register for GST or lodge a BAS.

Can I pay my BAS in instalments?
Yes, you can request a payment plan with the ATO. However, interest charges may apply. Discussing your options with a BAS agent can help you make the best decision for your circumstances.

Tips for Managing BAS Deadlines

  1. Set reminders: Mark BAS due dates on your calendar or use accounting software with built-in reminders.
  2. Work with an expert: A tax or BAS agent can ensure your forms are accurate and lodged on time.
  3. Keep records organised: Accurate record-keeping makes preparing your BAS easier and reduces the risk of errors.
  4. Lodge early: Avoid last-minute stress by submitting your BAS well before the due date.
