The short answer. Accountants can use ChatGPT and Claude for client letters, research starting points, and internal checklists, as long as tax return information stays out of the prompt or goes in only with the client’s written consent. Section 7216, the AICPA confidentiality rule, and the FTC Safeguards Rule all reach the same place: the firm decides what leaves its hands, and proves it.
Where ChatGPT helps a firm
Draft a letter explaining a CP2000 notice or document request from placeholder facts. Ask for a starting summary of a public rule, then read the rule. Turn an engagement process into a checklist. None needs a name, SSN, or return.
What stays out
Tax return information includes a client’s name, address, and identifying number when furnished for preparing a return. Keep returns, W-2s, 1099s, SSNs, and bank details out unless you have a signed Section 7216 consent in the form Rev. Proc. 2013-14 requires. The civil penalty is $250 per disclosure, up to $10,000 a year.
The rules beside Section 7216
The AICPA code bars disclosure of confidential client information without specific consent and permits a third-party provider under a confidentiality contract or with consent. The FTC treats tax preparers as financial institutions, requiring a written security program, provider oversight, and notice within 30 days for a qualifying breach. IRS OPR’s June 2026 guidance calls for secure, enterprise-approved tools.
The habit that makes it safe
Write prompts with [CLIENT], [PAYER], a rounded amount, and the tax year. Tell the tool to preserve labels, put real details back yourself, and check every figure and code section before client use.
What accountants use ChatGPT for
These uses begin with public, generic, or synthetic material and end with professional review.
- Drafting an outline for a client email from facts that contain no client identifiers
- Explaining a general accounting concept in plain language
- Creating a checklist for a recurring close or reconciliation process
- Brainstorming spreadsheet formulas with synthetic examples
- Editing generic training material and internal procedures
Client data that stays out of prompts
Use placeholders or synthetic records when the task needs structure. Keep the following data out of consumer and unapproved AI tools:
- Client and taxpayer names, addresses, email addresses, and phone numbers
- Social Security numbers, employer identification numbers, and other tax identifiers
- Tax returns, source documents, income, payroll, and withholding details
- Bank, routing, payment card, and account numbers
- Financial statements, ledgers, transactions, and unreleased results
- Portal credentials, passwords, and API keys

Five steps for safer use
- Start with policy. Define approved tools, prohibited data, review, reporting, and an owner in the AI acceptable use policy.
- Remove client context. Replace real records with synthetic examples and neutral placeholders before drafting the prompt.
- Use the approved account. Confirm the exact product, plan, settings, and connected features match company policy.
- Verify every result. Check facts, calculations, citations, professional requirements, and final language against authoritative sources.
- Report mistakes and exposure. Stop the workflow, preserve the relevant record, and follow the company reporting path.

Professional guidance
The IRS Office of Professional Responsibility says generative AI can create an unauthorized disclosure risk when taxpayer information is uploaded to unsecured or public systems. Its guidance directs tax professionals toward secure, enterprise-approved tools with confidentiality safeguards and calls for verification of AI-generated work. Apply that boundary to every prompt and attachment used in federal tax practice.
This guide provides operational information. Have counsel or the profession’s designated compliance owner review company policy and each approved use.
