Know the 2025 ATO Deadlines Early
The Australian Taxation Office (ATO) releases due dates each year depending on your income type and lodgement method. To stay ahead, the first step is to know what’s due and when.
Here are the key ATO deadlines in 2025:
- 31 October 2025 – Last day to lodge individual tax returns (if not using a tax agent)
- 28 February 2025 – Business tax return deadline (if lodging through a registered tax agent)
- 21st or 28th of the month – BAS due dates for GST-registered businesses (monthly/quarterly)
- 15 May 2025 – Due dates for company returns (for the majority of businesses under tax agents)
Tip: Add these dates to your digital calendar with reminders set one week in advance. You won’t be taken off guard that way.
5 Ways to Stay Ahead of Your Australian Tax Deadlines

Don’t leave your paperwork until June. Sorting through piles of receipts and bank statements can take hours if you wait until the last minute.
Instead:
- Keep digital copies of invoices and receiptsStore everything in cloud folders like Google Drive or Dropbox
- To keep track of your spending, use programs like Xero, MYOB, or QuickBooks.
- To keep track of your spending, use programs like Xero, MYOB, or QuickBooks
For business owners, this is especially important. Good record-keeping means fewer errors in your business tax return, and more deductions you can actually claim.
2. Separate Your Business and Personal Finances
If you’re a sole trader or small business owner, mixing personal and business expenses is a recipe for tax trouble. It makes your returns harder to prepare and can lead to mistakes.
Set up:
- A dedicated business bank account
- A business credit or debit card
- A proper bookkeeping system

- Estimate your tax liability in advance
- Make last-minute super contributions or asset purchases
- Adjust your invoicing or salary planning
If you’re a business owner, your tax agent can help you assess whether you’re on track or need to make changes before the financial year ends.

Automation isn’t just for tech companies—it can help anyone stay on top of taxes. Use technology to save time, reduce errors, and avoid missing ATO deadlines.
