As a business owner, you know how easy it is for important dates to slip your mind amidst the hustle and bustle of running your company. That’s why it’s crucial to stay on top of key financial year dates to keep your business compliant.

To avoid missing any important deadlines, take a moment to mark these dates in your calendar or set reminders. These include due dates for tax returns, BAS and super contributions.

By staying organised and keeping track of these dates, you’ll not only avoid late lodgment fees from the ATO but also ensure that your business runs smoothly.
