How to Avoid ATO Audit Headaches: A Guide for Small Business Owners

The good news? You can stay off the ATO’s radar and take the stress out of financial admin with a little help from Thriday.

Let’s unpack what the ATO is focusing on right now, what could trigger an audit, and how Thriday helps you keep things squeaky clean.

Why the ATO is turning up the heat

The ATO’s current mission is clear: crack down on non-compliant buinesses. Just 1% of debtors are responsible for a whopping $11 billion in unpaid tax. The ATO is going hard on this group—with powers like garnishee notices, director penalty notices, and even wind-up action being used against businesses that refuse to engage.

But it’s not just about the big offenders. The ATO uses data analytics and benchmarking to scan for anomalies across all small businesses. That means even a small inconsistency could raise a red flag.

What could trigger an audit?

The ATO keeps a close eye on certain behaviours that often lead to deeper investigations. Here are some key triggers to watch out for:

• Unusual claims or deductions – If your expenses are way outside the norm for your industry, expect questions.
• High cash transactions – Hospitality and retail businesses, take note. If you're dealing with a lot of cash, the ATO will want to see meticulous records.
• Consistent losses – A few bad years are fine, but if you’re always in the red, they might wonder if your business is actually a hobby.
• Inconsistent income vs lifestyle – Reporting low income but living large? The ATO can and will cross-check.
• Big GST or tax refund claims – Especially if they don’t line up with your income or expense records.

Record-keeping: Your first line of defence

Staying audit-ready means keeping solid records. You’re legally required to hang onto key business documentation for at least five years, including:

• Invoices and receipts for income and expenses
• Any calculations or estimates used in your tax affairs
• Notes on decisions, like how you calculated GST or PAYG
• Documentation showing the business purpose behind each transaction

But here's the thing. Keeping track of all that manually is a nightmare.
