Australian Taxation Office reminders for small business

If you run a small business, there are a few Australian Taxation Office (ATO) updates to be aware of this financial year.

From super payment deadlines and rate changes to keeping your ABN details up to date, these quick checks can help you stay compliant and avoid any surprises.

Key changes to be aware of:

Super guarantee contributions are due by 28 July

Super guarantee contributions must be paid to eligible workers by 28 July. Make sure you pay your employees' super guarantee in full, on time, and to the right fund to avoid penalties and interest. Payments are only considered ‘paid’ when they reach the employee’s super fund.

Small businesses are reminded that the super guarantee rate increased from 11.5% to 12% on 1 July 2025.

- For wages paid before 1 July, use the 11.5% rate, even if the work was done in June.

- For wages paid on or after 1 July, use the 12% rate, even if the work was done in June

Not-for-profits: self-review return due 31 October

If your non-charitable not-for-profit (NFP) has an active Australian business number ABN and is self-assessing as income tax exempt, you must submit the 2024–25 NFP self-review return by 31 October.

You can do this using the ATO’s online services for business or by calling the ATO’s automated phone service on 13 72 26, or through a registered tax agent.

If your NFP hasn’t lodged its 2023–24 return yet, you need to do that first as returns must be lodged sequentially.

Keep your ABN details current

Update your ABN within 28 days of any changes to stay eligible for grants, emergency support, and business opportunities.
