IRS AI Guidance Leaves Client Disclosure Question Open
The US approach of mapping existing professional duties onto AI use - rather than creating new rules - is a governance pattern worth noting as Australia considers similar questions.
Key points
- US IRS guidance applies existing Circular 230 professional duties to AI-assisted tax work, requiring human review and confidentiality protections.
- Whether tax preparers must disclose generative AI use to clients remains legally unresolved under US rules - a disclosure gap with broader parallels.
- Limited direct relevance to APS; the governance pattern of applying existing duty frameworks to AI use has indirect resonance for Australian regulated professions.
Implications for Australian agencies
- Monitor Policy teams working on AI disclosure or professional-services regulation may want to monitor how the IRS and AICPA resolve the client-notification question, as it could inform analogous Australian debates.
Implications are AI-generated. Starting points, not advice — see methodology for how they're framed.

The US IRS issued introductory guidance in June 2026 applying existing Circular 230 professional standards to AI-assisted federal tax practice, covering accuracy review, client confidentiality, and billing obligations. A key disclosure question remains unresolved: whether practitioners must notify clients when generative AI assists in preparing returns. The AICPA is advising voluntary disclosure as a precaution. The guidance explicitly flags generative AI failure modes - hallucinations, bias, and opacity - as ethical and legal risks, while stopping short of treating AI output as a substitute for professional judgment. Adoption is already broad, with surveys indicating 60% of practitioners using AI for tax work.
Implications for Australian agencies:
