September 2025

Here are the key tax dates and compliance reminders for September. Please reach out if you’d like help with lodgements, planning or reviewing your current position.

Key Dates

• 21 September 2025 – August 2025 monthly BAS due for lodgment and payment.

• 30 September 2025 –

  • PAYG withholding payment summary annual report due (if not already reported through STP).

  • Closely held trust trustees: TFN annual report due.

PAYG Instalments

If your income is tracking differently this year, now is a good time to review and vary your PAYG instalments. This can help smooth cash flow and prevent an unexpected tax bill at year-end.

ATO Compliance Spotlight

The ATO has flagged increased review activity this year in:

• Rental property deductions

• Gig economy income (ride share, delivery, freelancing)

• Cash-only transactions

• GST accuracy in BAS lodgements

Keeping good records is the simplest way to stay off the radar.

Tip for Individuals

If you haven’t lodged your 2025 tax return yet, remember that lodging through an agent extends your due date. Engaging early means more time to plan and optimise your position.
