What tax due dates apply for businesses in Australia?

In Australia, business owners file their income tax returns between 1 July to 31 October unless you’re registered with a tax agent. If you’re registered with a tax agent before 31 October, your tax return deadline may be extended until 15 May the following year. 

There are also some important tax deadlines in Australia for you to remember:

  • Goods and Services Tax (GST)
  • Business Activity Statements (BAS)
  • Fringe Benefits Tax (FBT)
  • Pay-As-You-Go (PAYG) if you’re an employer 

What do I do if I’ve missed the tax deadlines?

You may be liable for interest or penalties if you didn’t lodge and pay your tax on time. You can find more details on ATO’s website. If you can’t make payment on time, get in touch with ATO or an accountant to see if you can set up a payment plan using instalments.  

How can I file my taxes?

There are several ways to file your taxes. You can choose to either file your taxes yourself or via an accountant or a tax agent. 

  • DIY:  You can choose to lodge online through myTax if you operate your business via a sole trader structure. If you operate your business through other business structures (e.g., company, partnership, trust), you need to use an SBR (standard business reporting) enabled software or lodge by paper. You can find more details on ATO's website.​​
  • Via an accountant or a tax agent: if you are working with an accountant or a tax agent, they can take care of your taxes.

Business owners mark tax deadlines as important on their calendars to receive notifications as they approach. However, Beany makes it even easier.

Meeting your tax deadlines 

It’s important to plan ahead for the tax season. Beany accountants recommend setting aside some of your income in a separate bank accountant to ensure you won’t face any cash flow problems during tax times. In order to determine how much money you need to set aside, you’ll need to discuss this with your accountant as the number depends on your business’s situation.  It’s also important to keep accounting records such as receipts, bank statements, and invoices. You should keep these records for at least 5 years as per ATO’s requirement.
