AICPA is challenging the IRS on AI fee guidance. Firms still need the control layer.

On September 8, the Journal of Accountancy reported that AICPA is seeking clarification from the IRS on guidance suggesting tax practitioners should pass AI-related efficiencies to clients. The pricing question is unsettled. The operational expectations around diligence, confidentiality, competence, procedures and human review are much clearer.

The practical takeaway: whether a firm bills hourly, bundles services or uses value pricing, AI adoption creates a new operating-control problem. Firms need to know what tools are being used, what data touches them, who reviews outputs, what procedures apply and how evidence is retained.

1. Human review

IRS OPR guidance says AI-created documents, facts, citations and calculations require thorough human verification rather than blind reliance.

2. Secure data handling

Taxpayer information should not be uploaded to unsecured or public systems; firms need approved tools, access controls and confidentiality safeguards.

3. Firm procedures

OPR points to training, internal AI-use rules, secure data protocols, accuracy monitoring, third-party vetting and documentation of those processes.

4. Vendor review

External AI providers should be vetted before use, including how client data is stored, retained, reused and protected.

5. Usage evidence

Documenting AI usage and verification steps matters because the relevant professional duties remain with the practitioner and firm.

6. Pricing governance

AICPA is seeking clarification on whether the IRS language properly accommodates value pricing and the real costs and risks of AI adoption.
