The IRS Didn't Change the Rules. It Clarified Them.
July 30, 2026

Artificial intelligence is quickly becoming part of the modern tax workflow. Firms are using AI to streamline document processing, prepare workpapers, accelerate research, and reduce the time spent on repetitive administrative tasks. As adoption continues to grow, one question has become increasingly important:
How do existing professional standards apply when AI becomes part of the process?
The IRS Office of Professional Responsibility (OPR) recently provided an answer. Its latest guidance in Alert 2026-19, released June 24th, explains how the long-standing requirements of Circular 230 apply to practitioners using artificial intelligence.
The key takeaway is simple: AI may assist with the work, but it does not assume responsibility for the outcome.
For firms evaluating AI solutions, that's an important distinction. The conversation is no longer simply about whether AI can improve efficiency. It's about implementing technology in a way that supports the professional standards firms already follow.
Accountability Still Belongs to the Practitioner
The OPR guidance does not establish a new set of AI regulations. Instead, it reinforces existing expectations around due diligence, competence, confidentiality, and professional judgment.
Whether a return, workpaper, or client communication is prepared manually or with the assistance of AI, practitioners remain responsible for its accuracy.
This reflects an important principle that should guide every firm's AI strategy: technology can accelerate work, but it cannot replace professional review.
AI-generated content should be treated as a draft that requires validation by experienced professionals before it reaches a client or the IRS.
The Right AI Doesn't Replace CPAs. It Helps Them Focus on Higher-Value Work.
Much of a tax engagement involves work that is necessary but time consuming. Organizing documents, extracting data, preparing work papers, reconciling information across systems, and assembling review-ready returns consume valuable hours before a CPA begins applying professional judgment in final review.
AI has the potential to significantly reduce that administrative burden.
When repetitive work is automated, experienced professionals can spend more time reviewing complex issues, advising clients, and exercising the expertise that creates the greatest value.
That is where AI delivers its greatest benefit: not by replacing professionals, but by helping them spend more time doing the work only they can do.
Security and Governance Matter More Than Ever
The guidance also reinforces another important consideration: not all AI platforms are created equal.
Protecting taxpayer information remains a fundamental responsibility. Firms should understand how their AI solutions handle sensitive data, whether client information is securely protected, and what controls exist around access, storage, and retention.
As firms evaluate AI vendors, security, transparency, and governance should be considered alongside automation capabilities.
AI Adoption Requires Process, Not Just Technology
Successful AI implementation extends beyond selecting the right software.
The OPR encourages firms to establish policies for responsible AI use, provide employee training, document review procedures, and evaluate third-party tools before introducing them into production workflows.
These recommendations recognize that AI is most effective when paired with clearly defined processes and appropriate human oversight.
Looking Ahead
The IRS guidance reflects a broader shift taking place across the profession. As AI becomes more common, firms may be increasingly expected to demonstrate not only how they use AI, but how they govern it.
For tax professionals, that should be viewed as an opportunity rather than a limitation.
Responsible AI implementation can help firms improve efficiency while maintaining the quality, accuracy, and professional standards clients expect.
Technology may continue to evolve rapidly, but one principle remains unchanged:
AI can enhance the tax preparation process. Professional judgment remains essential.
