The IRS’s recently issued OPR Alert 2026-19 on responsible artificial intelligence use in federal tax practice may have far broader implications than many practitioners realize. While directed at tax practice before the IRS, the Alert raises important questions for tax attorneys, CPAs, enrolled agents, financial advisers, estate planners, trust officers, and other professionals who increasingly rely on AI tools to analyze tax returns, assist with tax planning, prepare written advice, communicate with clients, review documents, and support compliance functions. The Alert addresses due diligence, competence, written advice, confidentiality, supervision, documentation, and billing practices in an AI-driven environment.
