If you’re a sole trader in Australia, there isn’t just one tax deadline to worry about – there are several. The dates that apply to you will depend on how you lodge and whether you’re GST registered.
Here’s a rundown of the key ones to know.
End of the financial year: 30 June
Australia’s financial year runs from 1 July to 30 June. This is the cut-off for the income you’ll be declaring in your tax return, so it’s the date everything else flows from.
Lodging your tax return
Once the financial year ends, you have two main options:
If you’re self-lodging, and you don’t have an extension, your tax return is due by 31 October. From there, the ATO will prepare a Notice of Assessment, letting you know if you owe anything in income tax, student loan repayments, or the Medicare levy. You’ll have until the stated due date to square up.
If you’re filing through an accountant or tax agent (like Hnry!), your return is due by 15 May the next calendar year.
So for FY 2025/26, your return will be due:
- 31 October 2026, if self-lodging
- 15 May 2027, if lodging through an accountant or tax agent.
Ta-da!
BAS returns
If you’re registered for GST, you’ll have separate filing deadlines for your quarterly BAS returns. Each return is due on the 28th of the month after the end of your quarterly period.
This means your BAS returns will be due on:
- 28 October
- 28 February
- 28 April
- 28 July
The easy way to stay on top of it all
Keeping track of multiple deadlines across the year is a lot to manage on top of actually running your business. Hnry calculates and pays your taxes throughout the year as you earn, and lodges your tax return for you — so when EOFY rolls around, there’s no scramble.
