Business Activity Statement (BAS) Basics

If you’ve just started running a small business (or you’re thinking about starting one), you might be wondering whether you need to lodge a BAS. And if so, when and how you do it.

Why Lodge BAS?

Why do you need to lodge a BAS?

You’ll need to lodge a BAS if you’re registered for GST with the Australian Taxation Office (ATO). It’s compulsory to register for GST if your business turnover is more than $75,000 per year. Your BAS will help you to report and pay any of the following tax obligations that you might have:

  • goods and services tax (GST)

  • pay as you go instalments for any tax you need to pay

  • pay as you go withholding tax for any employees you have

When to lodge BAS

When do you need to lodge a BAS?

Most businesses need to lodge their BAS quarterly. By the following dates:

  • 28 October

  • 28 February

  • 28 April

  • 28 July

The ATO will automatically send you a BAS when it’s time to lodge. There are financial penalties if you don’t lodge on time. If your small business reaches an annual turnover of $20 million, you’ll need to lodge your BAS monthly.

How to pay BAS

How do you lodge a BAS?

You can lodge your BAS online, through a registered tax or BAS agent, or by mail. You can pay any tax you owe online via BPAY, debit card or credit card. If you’re due for a refund, the ATO will pay the amount into your nominated bank account.
