ChatGPT for accountants: what it can and can't do for Australian tax

Advisory Stack Australia editorial team

Generic ChatGPT is useful to an accountant for drafting, summarising and explaining concepts — but it is a poor fit for Australian tax work itself. It can draw on outdated or non-Australian sources, it doesn't cite where an answer came from, and it leaves no audit trail. For anything a client relies on, you need a tool grounded in ATO sources that you can verify, and you remain responsible for the output either way.

What ChatGPT is genuinely good at

Used for the right jobs, general-purpose AI like ChatGPT earns its place in a practice:

  • Drafting client emails, letters and plain-English explanations.
  • Summarising a long document or explaining a concept quickly.
  • Brainstorming the questions to ask, or how to structure a piece of advice.
  • Creating internal training material or first drafts you then refine.

Where it falls short for Australian tax

The problem is not that ChatGPT is unhelpful — it's that Australian tax is specific, and generic AI is not:

  • It can draw on non-Australian or outdated sources, so a confident answer can simply be wrong for the AU context.
  • It usually doesn't cite where an answer came from, so you can't click through and verify it.
  • It keeps no audit trail — nothing to show you reviewed and verified the output.
  • It has no built-in guardrail to stop it giving what reads like personalised tax advice.

The TPB angle

The Tax Practitioners Board's 2026 guidance is clear that using AI — any AI — does not replace professional judgement or transfer responsibility, and that you need client consent before putting client information into a third-party tool. That applies squarely to pasting client details into a public chatbot. The safe pattern is: use AI for the draft, verify against authoritative sources, and keep the evidence.

When to use a purpose-built AU tool instead

For the tax work itself — matching strategies, checking a client's position, producing something a client acts on — a tool built for Australian tax is far safer than generic ChatGPT: it grounds its output in ATO sources you can verify, logs your review, and keeps client data on Australian infrastructure. Advisory Stack is built this way. Use ChatGPT for the general drafting; use a grounded, purpose-built tool for anything that touches a client's tax position — and verify everything before you rely on it.
