The ATO does not have a person named Kevin personally deciding to audit you out of spite. It has data. Kevin just runs the report.
Audit anxiety is one of the most common, and most overblown, fears in small business. The reality is far less dramatic and far more predictable than most people assume: the ATO isn't rolling dice, it's comparing your numbers to patterns, and certain patterns reliably catch its attention.
Myth: Audits Are Random
They're not. The vast majority of ATO reviews start with data-matching: comparing what you've reported against what other data sources say, and against how similar businesses in your industry typically perform.
What Actually Gets You Flagged
- Figures well outside industry benchmarks: reporting margins dramatically different to similar businesses in your industry and location.
- GST claims that don't match your income tax return: inconsistency between BAS figures and annual return figures is an easy, automatic flag.
- Cash-heavy businesses with suspiciously round numbers: real businesses rarely report income in perfectly tidy figures every quarter.
- A pattern of late or amended lodgements: inconsistency invites a closer look.
- A lifestyle that doesn't match reported income: the ATO does look at this, and it's exactly as awkward as it sounds.
The ATO's Small Business Benchmarks
The ATO publishes industry-specific benchmark ranges for typical costs and profit margins. If your business reports figures well outside your industry's normal range, that alone doesn't mean anything's wrong, but it does make you statistically more interesting to a review algorithm.
What Happens If You Are Selected
Most reviews start small (a request for more information or clarification on a specific figure) rather than a full-blown audit. Responding promptly, clearly, and with proper records usually resolves it quickly. It's the ignoring-it approach that turns a simple query into a genuine problem.
How To Reduce Your Risk
Keep your books reconciled and current (see our guide on how often you should actually be doing your bookkeeping), make sure your BAS and tax return tell the same story, and lodge on time. None of this guarantees you'll never be reviewed (nothing does), but it makes any review short and boring, which is exactly the goal.

Let's Discuss Your SituationATO Audits: Common Questions
Rarely. Most reviews are triggered by data-matching: the ATO compares what you've reported against bank data, other agencies, and your lodgement history, then flags figures well outside typical patterns for your industry, such as a sudden jump in GST credits or numbers that swing wildly. Consistent, well-reconciled numbers don't stand out.
They're industry-specific ranges the ATO publishes for typical costs, profit margins, and expense ratios, built from the tax data of similar businesses. Sitting well outside your industry's typical range doesn't necessarily mean anything is wrong, but it does make a business statistically more interesting to a review algorithm looking for outliers.
No. A large share of ATO reviews are simply the system checking reported figures against data it already holds, and plenty close with no changes at all once figures are explained. It's a verification process built into the tax system, not an accusation, and responding calmly with proper records usually resolves it quickly.
Keep your books reconciled and current, lodge on time, and make sure your BAS and tax return figures tell the same story, since a mismatch is one of the easiest automatic flags. Knowing where your numbers sit against industry benchmarks and documenting anything unusual also helps. Consistency is the biggest factor within your control.
