BAS Due 25 November? Don't Just Lodge It — Understand Your Numbers

Your BAS is more than another ATO deadline. It could be telling you something important about your business.

It's that time of the quarter again.

You've got customers to look after, employees to pay, suppliers to deal with and a business to run.

And somewhere in the middle of all that, there's your BAS.

For many business owners, preparing the BAS is one of those jobs that gets pushed to the bottom of the list until the deadline approaches.

Sound familiar?

For eligible businesses lodging electronically through a registered tax or BAS agent, the September 2026 quarter BAS is due on 25 November 2026.

But rather than treating BAS as just another compliance obligation, here's something worth considering.

What are your business numbers actually telling you?

1. Sales Are Up. So Why Isn't There More Money in the Bank?

It's a question worth asking.

Your business might be generating more sales than last quarter, yet your bank balance tells a different story.

Perhaps customers are taking longer to pay. Maybe wages, materials or operating expenses have increased.

Or perhaps your profit margins aren't what you thought they were.

Your BAS isn't a profit and loss statement, but reviewing the underlying financial records is a good opportunity to identify these issues.

2. Are Your GST Figures Correct?

Accounting software has made bookkeeping much easier, but it doesn't mean every transaction is automatically correct.

A supplier invoice might have been coded incorrectly. A bank transaction may have been duplicated. Or GST may have been claimed on an expense that doesn't qualify.

These things happen, particularly when you're trying to manage the books yourself while running a busy business.

A little attention now can save a lot of work later.

3. Are You Putting Enough Money Aside for Tax?

Here's a trap some business owners fall into.

Money comes into the bank account, bills get paid, and whatever is left looks available to spend.

Until the BAS arrives.

GST collected from customers isn't business income you get to keep. And if you employ staff, PAYG withholding obligations need to be managed as well.

Setting money aside regularly can make BAS time considerably less stressful.

4. Is Doing Your Own BAS Really Saving You Money?

There's nothing wrong with preparing your own BAS if you know what you're doing and have the time.

But consider what your time is worth.

If you're spending evenings sorting receipts, reconciling transactions and checking GST codes, could that time be better spent with customers, quoting new work or growing your business?

And if your bookkeeping needs correcting later, those apparent savings can disappear quickly.

Sometimes getting professional help isn't simply about compliance.

It's about getting your time back.

5. Your Accountant Should Understand Your Business

At Business Growth HQ, we believe an accountant should do more than prepare forms and tell you how much tax to pay.

We want to understand how your business operates.

Are you making enough profit? Is cash flow becoming a problem? Are your operating costs increasing? Are there better systems you could be using?

Not every BAS review will uncover a problem. But having reliable financial records makes it much easier to identify issues and make informed decisions.
