Where this applies
The US tax authority's regulator of tax practitioners, reading existing Circular 230 duties for generative AI. It quotes the due-diligence duty in preparing, approving and filing tax returns and other papers, and says that when using generative AI practitioners must thoroughly review all AI-created documents and language before delivery to a client or submission to the IRS, verifying facts, citations and calculations, and cannot rely solely on AI. The guidance itself names no profession; Circular 230 (§ 10.3(b)) is what lets certified public accountants practise before the IRS. It binds work on US federal tax filings only, not statutory accounts or filings elsewhere, and it gives no figures on how many accountants use AI.
What this means
For accountants who prepare US federal tax filings, the regulator has put in writing that AI output does not carry the practitioner's responsibility: a return or document drafted with AI has to be checked by the person who signs it before it goes out.
What it does not yet show
It covers US federal tax filings only; it does not measure how many accountants use AI for filings or how often AI-drafted filings are wrong.
What you can check
Open IRS Office of Professional Responsibility Issue Number 2026-19 and find "practitioners must thoroughly review all AI-created documents and language".
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
