Final Release: Revised Interpretation Tax Services (ET sec. 1.295.160), AICPA Professional Ethic Executive Committee, July 15, 2026

The AICPA Professional Ethics Executive Committee (PEEC) has adopted critical revisions to its ethics interpretation on Tax Services (ET sec. 1.295.160). Formally released by the Professional Ethics Division on July 15, 2026, these revisions carry an official effective date of January 15, 2027, though early implementation is permitted.

Notice of these revisions will appear in the online edition of the Journal of Accountancy in July 2026. For CPAs and CPA firms with audit or other attest clients, these changes establish a more structured and rigorous framework for evaluating how tax advisory, planning, preparation, and representation services impact independence. This impacts services CPA firms provide to clients that require the maintenance of professional independence (such as audits, reviews, etc.)

This article provides a comprehensive walkthrough of the revised interpretation, detailing the structural changes, new requirements, and renumbered paragraphs to help you update your firm's quality control and independence policies before the new year.

Scope of Impacted CPAs and Firms

This revised interpretation directly impacts any CPA or CPA firm that provides both tax services and attest services to the same client. If your firm performs audits, reviews, compilations, or other attest engagements, and simultaneously assists those clients with tax planning, advisory, compliance, or representation, you must align your practices with these updated standards by January 15, 2027.

Key Structural Revisions & New Guidance

To make the code easier to navigate, the revised interpretation adds specific section headers and renumbers several paragraphs. Below is a detailed breakdown of the key revisions, cross-referenced to the paragraph numbers in the new ET sec. 1.295.160.

1. Unified Definition of Tax Services (Paragraph .01)

The revised interpretation begins with a unified, explicit definition of what constitutes "tax services" for independence purposes.

Revision Detail: Paragraph .01 has been expanded to explicitly list "tax advisory and tax planning services" as well as "preparation of a tax return, transmittal of a tax return, and transmittal of any related tax payment" under the umbrella of tax services.
What Remains: It retains the inclusion of signing/filing a tax return, having a limited power of attorney, and representing clients in administrative proceedings.

2. Explicit Identification of Independence Threats (Paragraph .02)

Prior to this revision, the general threats associated with tax services were not highlighted at the outset of the interpretation.

Revision Detail: A brand-new Paragraph .02 has been added to state that when a member provides tax services to an attest client, self-review, management participation, or advocacy threats to compliance with the "Independence Rule" [1.200.001] may exist.
Relocation Note: The previous paragraph .02, which defined "tax return," has been relocated and integrated into the new paragraph .06a.

3. A New Dedicated Section: "Tax Advisory and Tax Planning Services" (Paragraphs .03, .04, and .05)

One of the most significant changes is the creation of an entirely new section dedicated to tax advisory and tax planning.

Defining Advisory & Planning (Paragraph .03): This paragraph defines these services as advising an attest client on how to structure its affairs in a tax-efficient manner or advising on the application of a tax law or regulation. It lists seven specific examples of such services:
- Structuring domestic or international affairs.
- Structuring transfer-pricing arrangements, taking into account guidelines.
- Utilizing losses in a tax-efficient manner.
- Structuring capital-distribution strategies.
- Structuring senior executive compensation strategies.
- Structuring a not-for-profit client’s business to avoid breaching its tax-exempt status.
- Structuring investments to utilize tax incentives.
General Requirements & Conceptual Framework (Paragraph .04): Members performing advisory or planning services must meet all requirements of the "General Requirements for Performing Nonattest Services" interpretation (ET sec. 1.295.040). Crucially, the client must approve all significant assumptions and matters of judgment, and accept responsibility.
- Additionally, Paragraph .04 requires members to apply the "Conceptual Framework for Independence" (ET sec. 1.210.010) and outlines four factors to help determine if threats are at an acceptable level:
  1. The level of confidence that the tax service's output will be supported by applicable tax laws, regulations, or precedents.
  2. Whether the output is based on an established practice commonly used by the profession and complies with requisite levels of authority.
  3. Whether the service is performed under the assumption that the output will be specifically reviewed by the tax authorities.
  4. The significance of the tax services to the subject matter of the attest engagement (e.g., the financial statements).
Applying Safeguards (Paragraph .05): If threats are not at an acceptable level, members must apply safeguards, or independence will be impaired. Paragraph .05 provides three examples of potential safeguards:
- Using professionals who are not on the attest engagement team.
- Having an appropriate reviewer who was not involved in providing the tax services review the attest work or tax services performed.
- Obtaining preclearance of the transaction from the relevant tax authorities.

4. New Dedicated Section: "Tax Return Preparation and Transmittal Services" (Paragraphs .06, .07, .08, and .09)

The revisions restructure the rules for preparing and transmitting tax returns into a logical, sequential format.

Defining Preparation Services (Paragraph .06): This new paragraph defines preparation services as assisting clients with tax reporting obligations by drafting and compiling information (including tax due on standardized forms).
- It relocates and expands the definition of a "tax return" to include informational forms (e.g., estimated tax vouchers), extension forms, and Forms 990, 5500, 1099, and W-2.
- It also encompasses advising on the treatment of past transactions and responding to tax authority inquiries.
Preparation and Transmittal Safeguards (Paragraph .07 - formerly part of .03): Renumbered from .03 to .07, this paragraph specifies that self-review and management participation threats are at an acceptable level only if General Requirements (ET sec. 1.295.040) are met, the member does not have custody or control over the client's funds/assets, and the designated client individual reviews, approves, and signs the return prior to transmittal.
Custody and Control Clarified (Paragraph .08 - formerly part of .03): To eliminate ambiguity, the old prose clarifying "custody and control" is restructured into a clean, bulleted list in Paragraph .08. The following are explicitly not considered custody or control over client funds:
- Making authorized electronic tax payments pursuant to prescribed criteria.
- Affixing the client's depository account information on a return.
- Remitting a client's check made payable to the taxing authority.
Signing and Filing Returns (Paragraph .09 - formerly .04): Renumbered from .04 to .09, this paragraph governs signing and filing on behalf of management.
- Subparagraph (a) has been revised to clarify that taxing authority electronic procedures (such as U.S. Forms 8879 or 8453) must, at a minimum, meet the standards for electronic return originators and officers outlined in Form 8879.
- Subparagraph (b) continues to permit signing and filing if an authorized management individual provides a signed statement with the necessary representations (i, ii, and iii).

5. Added Section Headers & Renumbered Paragraphs for Representation

The remaining subsections have been renumbered and received descriptive section headers to match the new document structure.

Authorized Representation in Administrative Proceedings (Paragraph .10 - formerly .05): Adds the section header and renumbers the paragraph to .10. It reinforces that acting as an authorized representative does not impair independence, provided General Requirements (ET sec. 1.295.040) are met and the member obtains client agreement prior to committing the client to any resolution.
Services Involving Power of Attorney (Paragraph .11 - formerly .06): Adds the section header and renumbers the paragraph to .11. It clarifies that self-review, management participation, and advocacy threats are acceptable under ET sec. 1.295.040, provided that the use of POA is limited strictly to tax matters and the member does not bind the client to any agreement.
Services Involving Representation in Court (Paragraph .12 - formerly .07): Adds the section header and renumbers the paragraph to .12. It maintains the strict rule that representing an attest client in court to resolve a tax dispute impairs independence because threats cannot be reduced to an acceptable level.
- Revision Detail: The definition of "court" has been simplified by deleting specific references to "tax, district, or federal court of claims and the equivalent". Instead, it now broadly and cleanly encompasses any "U.S. federal, territorial, tribal, state, or local court, or an equivalent foreign or international forum".
Transition Provisions & Effective Dates (Paragraphs .13 and .14 - formerly .08 and .09): These paragraphs are renumbered to .13 and .14. Paragraph .14 maintains that paragraph .11 (the POA rule, formerly .06) has been effective since December 15, 2014.

Action Items for CPAs and CPA Firms

With the January 15, 2027 effective date approaching, firms should take the following proactive steps:

Conduct an Engagement Inventory: Identify all attest clients for whom your firm also provides tax advisory, tax planning, or tax return preparation services.
Evaluate Threats Under the New Framework: For tax planning and advisory engagements, document your threat assessment using the four factors in paragraph .04 and apply appropriate safeguards (such as separating the tax and audit teams) as detailed in paragraph .05.
Review Quality Control over Transmittals & Signings: Ensure your procedures for electronic filing and signing strictly comply with the updated requirements in paragraph .09, particularly regarding U.S. Form 8879 standards.
Update Internal Training: Educate partners, tax staff, and audit staff on the new structural headers, threat evaluations, and custody/control definitions.

By adopting these changes early, your firm can ensure seamless compliance and maintain its commitment to professional objectivity and independence.
