May 2025 Business Calendar: Key Dates and Tips for Australian Small Business Owners

May is here, and with it comes one of the most important windows of the business year—tax planning season.

With just two months left until 30 June, it’s the perfect time to get ahead, finalise important obligations, and sharpen your strategy for a strong financial year-end.

Here’s what to mark in your calendar:

Key Dates for May 2025:

📌 Stay organised and ahead of your deadlines.

📅 7th May – April Monthly Payroll Tax 📊

Time to lodge and pay your April payroll tax if you’re over the threshold. Use this checkpoint to review wages paid and check if you're approaching the annual threshold early.

📅 11th May – Happy Mother’s Day 💐

A reminder to celebrate the mums in your life—both at home and in your workplace. Small gestures of appreciation can go a long way!

📅 15th May – 2024 Tax Return Lodgement (via Tax Agent) 🧾

If you’ve engaged a registered tax agent, this is your final date to lodge your 2024 income tax return (unless you have special arrangements). Don’t risk late lodgement penalties!

📅 15th May – STP Finalisation for Closely Held Payees 🖥️

Small employers with only closely held payees (such as directors or family members) must finalise 2025 Single Touch Payroll data by this date. This ensures your payroll is ready for year-end reporting.

📅 21st May – April Monthly BAS/IAS 📈

BAS and IAS for April are due. Keeping up-to-date with monthly lodgements can help you spot cash flow trends early and plan smarter for EOFY.

📅 26th May – March Quarter BAS (via Tax Agent) 📄

If you lodge your March quarter BAS through a tax agent, this is your due date. If you haven't lodged yet, check in with your agent to make sure everything’s on track.
