As a business owner or investor, time is always tight. So it’s no surprise many people now turn to AI tools like ChatGPT for quick answers on tax deductions, super contributions or structuring ideas. The responses sound confident, arrive instantly and cost nothing. What could go wrong?

Plenty.

The Australian tax and super system is complex, highly fact-specific and constantly changing. While AI can be a useful starting point, relying on it for decisions can expose you to audits, penalties and poor financial outcomes. We’re increasingly seeing the clean-up work when AI advice goes wrong.

Where AI Can Help (and Where it Can’t)

AI is quite good at explaining basic concepts in plain English. It can help you understand what “negative gearing” means, outline the difference between concessional and non-concessional super contributions, or prompt you to think about record-keeping. Used this way, it can save time and help you ask better questions.

The problem starts when AI moves from explaining concepts to giving “advice”.

Tax and super outcomes depend on your specific facts: your income levels, business structure, age, residency status, assets, timing and future plans. AI does not know these details unless you provide them—and you generally shouldn’t. Even then, it cannot exercise judgement or balance competing risks the way an experienced adviser can.

The Accuracy Risk: Confident, but Wrong

AI tools are known to “hallucinate” – that is, provide answers that sound authoritative but are incorrect or incomplete. In practice, this can mean:

  • Claiming deductions that don’t apply to your circumstances
  • Miscalculating capital gains tax or ignoring integrity rules
  • Suggesting super strategies that breach contribution caps or eligibility rules
  • Quoting legislation, cases and rulings or concessions that don’t exist or are out of date.

These errors are rarely obvious to a non-expert, but they are normally obvious to the ATO, courts and experienced advisers.

A recent decision handed down by the Administrative Review Tribunal highlights some of the key problems. In Smith and Commissioner of Taxation [2026] ARTA 25 the taxpayer appeared to rely on AI tools to identify cases which supported their argument, but this approach was shot down by the Tribunal. Some of the cases didn’t exist and others were simply not relevant to the matter being considered.

If the person using the AI tool doesn’t verify the existence of the cases provided by the tool and read them to ensure their relevance then “the Tribunal’s resources are being wasted, as the Tribunal must look for cases that don’t exist and read cases that have no relevance at all”.

ATO Scrutiny is Increasing, not Decreasing

The ATO isn’t anti-AI—they use it internally for fraud detection and analytics. But for you? The ATO’s misinformation guide makes it clear that AI tools can provide false, inaccurate, incomplete or outdated information. The ATO’s message is to verify everything, or face the music. Surveys reveal 64% of businesses seek AI accounting help first, only for pros to unscramble the mess—wasting time and money.

When something is wrong, the ATO will generally amend the return, charge interest and may apply penalties—even if the mistake came from AI advice rather than intent. Please contact our team if you have any questions.
