We know the juggle is real when running a small business! Between tax deadlines, BAS lodgements, and super payments, it’s easy for those key dates to sneak up on you.

Why Staying Ahead with Your Bookkeeping Matters
Before we get into the dates, let’s talk about why being prepared matters so much.
Small business owners wear many hats – marketing, operations, sales – and bookkeeping can sometimes fall to the bottom of the priority list. But here’s the truth: staying on top of your bookkeeping can save you time, money, and headaches down the line.
Missing key dates can result in penalties from the Australian Taxation Office (ATO) or missed opportunities for deductions. By marking your calendar now, you’re giving yourself a head start to keep your finances in order.
Here’s What Staying Prepared Means for You:
- Peace of mind knowing your ATO obligations are covered
- More time to focus on growing your business (instead of chasing deadlines)
- Better cash flow management—no more surprise payments throwing off your budget
Sound good? Let’s get into the key dates you need to know for 2025. Grab your calendar—it’s time to get organised!
