The AI audit trail: proving you verified AI tax advice
An AI audit trail is a record showing that a registered tax agent reviewed and verified AI-generated output before relying on it or giving it to a client. Because the TPB Code of Professional Conduct keeps you accountable for AI output, being able to show what you checked — and when — is the difference between a defensible decision and an unverified one.
Why an audit trail matters now
Regulators have made the expectation explicit. The Tax Practitioners Board's 2026 draft guidance on AI and the Code of Professional Conduct states that using AI does not reduce or transfer a practitioner's responsibilities — you remain accountable for the advice. In parallel, the ATO has publicly warned taxpayers about relying on AI for tax.
Put together, that means the burden of proof sits with you: if an AI-assisted output is ever questioned, you should be able to demonstrate that a qualified person reviewed it. An audit trail is how you do that.
What a good AI audit trail captures
It does not need to be complicated. At a minimum it should record:
- That a specific person reviewed a specific AI output, and when.
- The sources the output was grounded in (e.g. ATO pages, legislation) so a reviewer can click through and confirm.
- An acknowledgement that the practitioner verified the output before it was relied on or sent to a client.
- Enough context to reconstruct the decision later — the client situation, the output, and the review.
How Advisory Stack builds this in
Advisory Stack is designed so the evidence trail is a by-product of normal use, not extra admin. AI-assisted outputs are labelled as general information to be verified, they cite the ATO sources behind them, and a verify-before-you-advise acknowledgement is logged when a practitioner signs off. That record is exportable if the TPB or your PI insurer ever asks.
You remain the adviser of record throughout — the platform supports your judgement and keeps the receipts; it does not make the decision for you.
The takeaway
AI is a legitimate tool in a modern tax practice, but the accountability never moves. Choose tools that make verification easy and that leave you an evidence trail, review every output with your own professional judgement, and keep the record. If it is ever questioned, that trail is what protects you.
