June is here—and that means we’re in the final stretch of the financial year!
This is a crucial time for business owners to get everything in order—lodging your returns, locking in deductions, and getting ready to close the books for a fresh start in July.
With so much happening, it’s important to stay ahead of your deadlines, maximise your tax strategies, and prepare for a strong year-end finish.
Here’s what to mark in your calendar this month:
Key Dates for June 2025:
📌 Stay organised and ahead of your deadlines.
📅 5th June – 2024 Tax Return Lodgement (via Tax Agent) 🧾
If you’re lodging your 2024 tax return through a registered tax agent, this is the extended due date. Don’t leave it too late—penalties for late lodgement can be steep!
📅 7th June – May Monthly Payroll Tax 📊
For businesses over the threshold, lodge and pay your May payroll tax. A great checkpoint to review your wages for the year.
📅 15th June – Superannuation Contributions for 2025 Tax Deduction 💼
Want a tax deduction for the 2025 financial year? Make personal or employer super contributions by this date—especially important for business owners managing their own super!
📅 21st June – May Monthly BAS/IAS 📈
Your May BAS/IAS is due. Staying on top of these lodgements helps you keep your cash flow in check.
📅 25th June – 2025 Fringe Benefits Tax (FBT) Return 🚗
Lodge and pay your 2025 FBT return if applicable. Not sure if you need to lodge? Let’s chat—fringe benefits can be tricky!
📅 30th June – End of Financial Year! 🎉
It’s here! A few important reminders:
Take odometer readings for all work vehicles—this is essential for your logbooks and FBT records.
Finalise any last-minute tax strategies like asset purchases or deductible payments.
Celebrate your wins, big or small—EOFY is a big milestone!
