Regulatory Foundation, Our Actual Obligations When Using AI on Client Work

This is the project's bedrock reference, Guardrails is the plain-English layer on top of it. It states what each governing rule is, what it actually requires, and the specific obligation it creates when you put client data into, or rely on output from, an AI tool.

Every claim below was researched against primary sources (IRS, FTC, eCFR, Federal Register, AICPA) and adversarially fact-checked. Confidence levels and "not-yet-final" flags are marked honestly, per this project's own rule, we cite accurately or we flag the uncertainty.

Scope and disclaimer. This is an internal educational summary for AI Lab members, not legal advice. It reflects research current to 2026 and the law changes. Verify against the primary source and your own counsel/state board before relying on any point for a specific situation.


The short version (the stack you're standing on)

When you feed client data to an AI tool, four binding obligations can attach at once:

  1. IRC §7216 / §6713, you may need the client's written, knowing-and-voluntary consent before taxpayer return information goes to a third-party AI service. (Criminal + civil. Settled law.)

  2. FTC Safeguards Rule / IRS WISP, the AI vendor is a service provider you must vet, bind by contract, and monitor; client data must be encrypted; the tool must be assessed under your written information security plan. (Settled law, in full effect.)

  3. Revised SSTS (effective 1/1/2024), you remain fully responsible for the work product whether or not you used AI, and you must protect data and exercise judgment when relying on tools. (Enforceable for AICPA members.)

  4. Circular 230, competence and due diligence today; a proposed amendment would add explicit technological-competence and data-security duties. (Proposed, not yet final.)

Plus two more that can attach: the AICPA Confidentiality Rule (ET §1.700.001), consent or a confidentiality agreement with the AI vendor, independent of §7216; and, for a Georgia CPA, state law, Rule 20-12-.11 (confidentiality) and 20-12-.19 (which pulls AICPA standards into your license). Attest work adds SSARS/GAAS (AI is evidence under AU-C 500, you stay responsible).

Bottom line: before AI touches real client data, get §7216 consent where required, vet and contractually bind the vendor under your WISP (and the Confidentiality Rule), encrypt, and never stop being the reviewer of record.


1. IRC §7216 & §6713, disclosure/use of taxpayer return information

What it is. §7216 is a 1971 criminal statute; §6713 is its companion civil penalty. Together they prohibit a tax return preparer from knowingly or recklessly disclosing or using taxpayer "return information" without authorization. Final Treasury Regulations took effect Dec. 28, 2012 (temporary regs Jan. 4, 2010). (Confidence: high, 3-0 verified.)

Penalties, the precise 2×2 (verified against primary statutory text).

Base Identity-theft enhanced (where §6713(b) applies)
§7216, criminal (requires "knowingly or recklessly") misdemeanor: ≤$1,000 fine and/or ≤1 year + costs $100,000 fine and/or ≤1 year
§6713, civil (no scienter, effectively strict liability) $250 per disclosure/use, $10,000/yr cap $1,000 per disclosure/use, $50,000/yr cap
  1. §6713 civil liability requires no mental state. §6713(a) imposes the penalty on the act of disclosure/use itself, unlike §7216's criminal charge, which needs "knowingly or recklessly." Practical upshot: an accidental paste of TRI into a consumer tool can carry the civil penalty even with zero intent.

What it requires with AI, the clean rule. §7216 treats tax return information (TRI) broadly: information furnished for return preparation and anything the preparer derives or generates from it. "Use" = relying on TRI to take or permit an action; "disclosure" = making TRI known to another person in any manner. Consent is the baseline unless §7216 or a specific 26 CFR §301.7216-2 exception authorizes the use/disclosure; consent must be knowing and voluntary and meet the format/content rules of Rev. Proc. 2013-14.

AI is not a special case, it is analyzed under the existing use/disclosure rules. The answer is a qualified no: AI use is not automatically a permitted §7216 use, but it is not categorically prohibited or always consent-triggering either.

The operative test: If the AI use fits a specific §301.7216-2 exception, no separate §7216 consent is required. If it does not, the firm needs valid written taxpayer consent, or must not put TRI into the tool.

Generally SAFE without separate consent (the use is functionally just preparing that client's return, or auxiliary services):

Generally REQUIRES consent, or should be PROHIBITED (outside the prep/auxiliary lane):

Defensible firm-policy standard: Client TRI may be used with AI only through firm-approved systems. Approved systems must be covered by a firm-level contract/DPA, prohibit model training and product-improvement use of client data, provide zero or minimal retention for the specific features used, restrict human access, identify subprocessors, maintain appropriate security controls, avoid unauthorized offshore access, and be used solely for preparing/assisting the client's return or related auxiliary services. Public or personal AI accounts may not be used with client-identifiable or return-derived information. Uses outside those limits require §7216 review and, where applicable, valid written taxpayer consent.

Note also a distinction: a separate §7216-format consent is only legally required when the use isn't already permitted, but disclosing your gen-AI use to clients (and getting consent) is often good risk management regardless, per AICPA/CNA guidance. (This is why the auxiliary- services exception is not a green light to skip the conversation.)

Enterprise / zero-data-retention (ZDR) AI: better, but NOT automatically exempt

A common and dangerous oversimplification is "enterprise tool with a data agreement = compliant." The truth is more precise. "Public/general-purpose AI" is practitioner shorthand, not a statutory category, §7216 doesn't care whether a tool is "public." It cares whether TRI was used or disclosed. So tools sit on a spectrum:

Tier What it is §7216 posture
Consumer / public AI Personal/free/Pro account, no firm DPA, vendor may train/retain, unmanaged Generally no client TRI unless valid consent (or no TRI entered)
Enterprise / ZDR AI Firm workspace or API with DPA, no-training, zero/minimal retention, U.S. processing Potentially permissible without separate consent, but only if the use fits a §301.7216-2 exception. Not automatic.
Internal / self-hosted AI Model runs fully inside the firm's environment Usually an internal-use question, not a third-party disclosure: a model running on firm-controlled hardware is not a "person" under IRC §7701(a)(1), so no "making known to any person" occurs (cross-client training/reuse can still create a separate "use" problem)

The key insight: ZDR makes the disclosure more defensible; it does not make §7216 disappear. The disclosure happens the moment the firm transmits TRI to the vendor. Enterprise/ZDR terms help show the vendor isn't making an independent prohibited use of the data, but the firm still needs a §301.7216-2 basis for the disclosure itself (same-firm U.S. internal use, U.S. auxiliary/contractor service for prep, etc.). Unless the model is fully self-hosted, it's still a third-party disclosure.

The self-hosted argument, and its honest limit. The reason a fully local model escapes the disclosure analysis is textual, and the chain is worth spelling out because each link is verified: (1) §7216(a) prohibits a preparer's disclosure of TRI; (2) "disclosure" is defined as "making tax return information known to any person in any manner whatever" (26 CFR §301.7216-1(b)(5)); (3) §301.7216-1(b) does not independently define "person", it defines seven terms (tax return, preparer, TRI, use, disclosure, hyperlink, request for consent) and "person" is not one, so the IRC-wide default applies; (4) IRC §7701(a)(1) defines "person" for the whole title as "an individual, a trust, estate, partnership, association, company or corporation", software is none of those; (5) therefore inference on firm-controlled hardware makes TRI known to no person, and the §301.7216-3 / Rev. Proc. 2013-14 consent regime is not triggered for the AI step.

The one attack surface (and why "genuinely local" closes it). The only real counterargument is that the vendor who shipped the model or distributed the weights is somehow "implicitly receiving" the information when you run their software. That argument is weak: "disclosure" requires making TRI known to a person, and a vendor that cannot observe your prompts (no telemetry, no cloud fallback, no remote access) is made aware of nothing. But it is exactly the surface the position turns on, which is why "genuinely local" is load-bearing: kill telemetry, crash reporting that includes content, cloud fallback, auto-update channels that phone home with data, and vendor support access. If any of those carries TRI off the box, that transmission is the disclosure, and the whole analysis flips. This is a strong reading of the plain text, but it is not blessed authority for AI. As of June 2026 there is no IRS guidance, ruling, or case addressing AI under §7216, the most recent §7216 guidance predates the technology (Rev. Rul. 2010-4, newsletter/bulletin service providers; Rev. Rul. 2010-5, professional-liability insurers; plus the 2012 final regs). The gap cuts both ways: the IRS has not confirmed the local-model path and has not asserted local inference is a disclosure. Use this reasoning internally with confidence; do not represent it as IRS-blessed, and run any client-facing "no consent needed because it's local" language past counsel and your carrier first. The conservative posture (consent where you'd otherwise get it, de-identification, reviewer-of-record) does not depend on this conclusion being right. (Two notes: this answers the disclosure prong only, §7216 still governs use, so fine-tuning a local model on client data is a separate, unguided "use" question; and the §301.7216-2(d) service-provider exception that a cloud vendor might invoke is itself narrow and conditional, (d)(2) covers contractors for "programming, maintenance, repair, testing, or procurement of equipment or software used for tax return preparation" and requires written §6713/§7216 penalty notice, which is why local is the cleaner lane.)

These are four separate concepts, don't let one stand in for another:

Use-level matters more than tool brand:

Minimum diligence before approving an enterprise AI tool for client TRI, get written confirmation of: (1) no training/model-improvement on prompts, files, outputs, embeddings, or feedback; (2) true ZDR for the specific endpoints/features used (not a marketing line); (3) no persistent application state unless necessary and approved; (4) U.S.-only processing/access (absent §7216 consent); (5) no third-party/downstream tool calls with TRI unless each is separately vetted; (6) confidentiality + subprocessor terms appropriate to TRI; (7) vendor human-access restrictions; (8) §7216/§6713 contractor-notice mechanics where access is possible; (9) use limitation (data used only to provide the service to the firm); (10) CPA final review, AI output is never the final substantive tax determination. (CNA/AICPA risk-control guidance aligns: ask how data is stored, whether it trains models, who can access it, retention, and de-ID.)

2. FTC Safeguards Rule (GLBA) & the IRS WISP

What it is. Under the Gramm-Leach-Bliley Act, tax/accounting professionals are legally classified as "financial institutions." The FTC Safeguards Rule (16 CFR Part 314) expressly lists "tax preparation firms" (§314.2(h)) as covered. The Rule took full effect June 9, 2023 and is current through 2026. The IRS WISP (Pub 4557 / Pub 5708, attested to on Form W-12 at PTIN renewal) is the functional equivalent of the required program. (Confidence: high, 3-0.)

What it requires. A comprehensive, written information security program with administrative, technical, and physical safeguards appropriate to your firm's size and complexity, including:

What it requires with AI. An AI/cloud vendor that receives, processes, or can access customer information is a "service provider." So before routing client data to it you must: vet its security, get a contract/DPA that requires it to maintain safeguards (and, practically, address data retention, no-training-on-inputs, and sub-processor disclosure), confirm encryption, and reassess periodically. A consumer free-tier tool with no such terms generally cannot satisfy this, which is the legal backbone of "anonymize or use an enterprise tool with a data agreement."

3. AICPA Code of Professional Conduct & revised SSTS (effective 1/1/2024)

What it is. The Statements on Standards for Tax Services (SSTS) are enforceable tax practice standards binding on AICPA members (enforced under ET §§1.300/1.310 of the Code), not advisory, but they bind members, not every state-licensed CPA per se. The revision was adopted May 18, 2023 and is effective Jan. 1, 2024, adding three new standards, two of which bear directly on AI. (Confidence: high, 3-0.)

What it requires with AI. (Standard- and section-level summaries below; we don't quote granular sub-paragraph numbers verbatim, verify exact wording against the published revised SSTS before relying on a specific clause.)

AICPA Confidentiality Rule (ET §1.700.001), a consent duty separate from §7216. The Code's Confidential Client Information Rule prohibits a member from disclosing confidential client information without specific client consent. Long-standing AICPA guidance on using a third-party service provider (the outsourcing interpretation) is that, before disclosing confidential client information to an outside provider, a member should either obtain client consent or enter into a contractual confidentiality agreement with that provider. Applied to AI: an AI vendor that can access client information is exactly such a third-party provider, so the confidentiality rule points to the same control set as the §314.4(f) Safeguards duty (a confidentiality/DPA contract) and §7216 (consent). This is a separate, independent obligation: even where a §7216 exception means no tax-consent form is required, the Confidentiality Rule still requires either client consent or a confidentiality agreement with the AI vendor.

The specific interpretations. Key structural point that resolves a common citation confusion: the third-party-service-provider rules are codified in parallel under three different ethics rules, so all three numbers are correct and address different facets:

Verification status: the three section numbers and the contract-or-consent / notify / supervise substance are corroborated across multiple independent authoritative sources (JofA, AICPA- authored, which quotes §1.700.040 verbatim; The Tax Adviser; CPA Journal), and one source expressly ties all three together ("…under ET Sections 1.150.040, 1.300.040, and 1.700.040"). ⚠️ The canonical AICPA Code is published as a non-machine-readable PDF, so this is authoritative-secondary verified, not a verbatim primary pull, open the live Code PDF to confirm exact wording before quoting it in a client-facing document.

This is the cleanest statement of the reviewer-of-record principle anywhere in the stack: AI is a tool; the professional owns the result.

4. Treasury Circular 230, competence & due diligence

What it is. Circular 230 governs practice before the IRS. Today, §10.35 imposes a general competence duty and the rules require due diligence. A proposed rule (REG-116610-20, 89 FR 105234, published Dec. 26, 2024) would amend it. (Confidence: medium, the existence and content of the proposal are verified, but it is PROPOSED, not final.)

What's BINDING NOW (verified to live text, these already reach AI use, no amendment needed).

What the proposal would add.

Status / caveat. Comment period ran through Feb. 24, 2025. As of this research it is not final and not enforceable. Treat technological-competence and incident-response language as the direction of travel, not yet binding, track finalization. The existing general competence duty under §10.35 still applies now.

5. SSARS (AR-C) & GAAS (AU-C), AI in attest work

(Relevant only if you perform compilations, reviews, or audits. For tax/bookkeeping-only practices this is background.)

What it is. The accounting/auditing standards that apply when AI assists attest work.

What's settled.

Bottom line for attest work: AI is treated as an automated tool inside the existing GAAS framework, same evidence, documentation, and professional-skepticism duties. The CPA remains responsible; AI output is evidence to be evaluated, never accepted on faith. Watch for ASB guidance landing around end of 2026.

6. Georgia State Board of Accountancy, your licensing jurisdiction

What it is. Charlie is Georgia-licensed. The GA Board (rules in Ga. Comp. R. & Regs. Chapter 20-12, under O.C.G.A. Title 43, Chapter 3) sets binding conduct and CPE rules on top of federal and AICPA standards.

What's settled.

Bottom line for a GA CPA: No extra AI-specific rule to follow in Georgia, but you carry a state confidentiality duty (20-12-.11), and Georgia enforces AICPA standards via 20-12-.19, so the AICPA Code + SSTS effectively bind you through your license. Keep current on the 4 ethics CPE credits.

6A. Other states, for non-Georgia AI Lab members (check your own jurisdiction)

This doc is anchored to a Georgia license, but AI Lab members practice nationwide. Two layers reach AI use in most states regardless of where you sit, on top of the federal stack above:

  1. State board confidentiality + AICPA-incorporation rules. Most state boards (like GA 20-12-.11/-.19) impose a confidentiality duty and incorporate AICPA standards into the license, so the AICPA Code + SSTS effectively bind you through your state board even though SSTS technically bind "AICPA members." Check your board's confidentiality and standards rules.

  2. State data-security & breach-notification laws can attach when client data is mishandled in an AI workflow. Examples, each now verified against an authoritative/primary source (members still confirm current thresholds for their own state):

Takeaway for the library (national audience): state the federal stack as the floor, then say "check your state board's confidentiality/standards rules and your state's data-security and breach-notification law" rather than asserting any one state's specifics. The four above are verified; other states have parallel regimes, members confirm their own.


What this means in practice, the pre-flight checklist

Before any client data goes into an AI tool, or any AI output goes into a deliverable:


Watch items & remaining nuances

The original open questions on SSARS/GAAS (§5), Georgia (§6), the AICPA Confidentiality Rule (§3), dedicated gen-AI guidance, and vendor contract terms are now answered above. What remains is forward-looking or fact-specific:

  1. ASB AI guidance (expected ~end of 2026). No final AI-specific auditing standard exists yet, the ASB is considering generative-AI/agentic-AI/data-analytics guidance. Track for a draft.
  2. Final Circular 230 amendment. The technological-competence (§10.35) and data-security (§10.33) provisions remain PROPOSED, not final. Track finalization.

  3. Exact ET subsection numbering for the AICPA third-party-service-provider interpretation should be confirmed against the live Code (this pass relied on AICPA/JofA coverage).

  4. "Is an AI-vendor transfer a 'disclosure'?" Under both §7216 and GA Rule 20-12-.11, applying the confidentiality duty to a specific AI data-flow is a reasonable inference, not spelled out in the rule text, a fact-specific judgment, so favor the conservative reading (consent or DPA).

  5. Precise §314.4(f) Safeguards contract language / whether a specific DPA form is expected.
