The ATO are good people. They rarely audit people for no reason. Here are some reasons they will target entities for audits:
1. Performances are not in line with industry benchmarks
2. Poor governance (late lodgers, late payers)
3. Tip offs
4. Overseas structures (is your holding company in the Cayman Islands?)
What is the best way to avoid an audit? Do you have plans in place to make sure you are controlling the above risks to fly under the radar?
