Key takeaways for how to document client consent for conflict of interest waivers
- Decline the engagement if a conflict may exist or develop before it starts, unless you obtain informed consent from each client, according to The Tax Adviser.
- A conflict exists when there is a significant risk that representing one client will be materially limited by duties to another client, former client, third person, or personal interest, according to Legal Information Institute.
- Confirm the informed consent in writing within a reasonable period, but no later than 30 days after the conflict is known, according to Journal of Accountancy.
- Retain copies of the written consents for at least 36 months from the conclusion of the representation, according to Legal Information Institute.
- Provide the written consents to any Internal Revenue Service officer or employee on request, according to Legal Information Institute.
The mandatory written consent rule
The core prohibition under Circular 230 is absolute: a practitioner shall not represent a client before the Internal Revenue Service if the representation involves a conflict of interest, except as provided by paragraph (b) of the section, according to Legal Information Institute. This rule establishes the baseline restriction that applies to all practitioners practicing before the IRS. The exception to this prohibition relies entirely on the client's consent. Specifically, each affected client must waive the conflict of interest and give informed consent, which must be confirmed in writing by each affected client at the time the existence of the conflict of interest is known by the practitioner, as stated by Legal Information Institute.
The requirement for written confirmation is not merely a best practice but a mandatory condition for the waiver to be valid. The Tax Adviser clarifies that Section 10.29(b) requires the CPA to obtain the written informed consent of each client, confirmed at the time that the CPA knows of the existence of a conflict of interest, according to The Tax Adviser.
For tax professionals managing multiple client relationships, this means that identifying a potential conflict triggers an immediate documentation duty. The practitioner must ensure that the written consent is obtained and confirmed at the moment the conflict is known. The rule does not allow for verbal consent to substitute for the written confirmation required by the regulation, as the text explicitly demands confirmation in writing by each affected client, according to Legal Information Institute.
Defining the conflict: significant risk and material limitation
The trigger for mandatory consent documentation is a specific risk condition, not a general ethical concern. According to Legal Information Institute, the condition exists when there is a significant risk that the representation of one or more clients will be materially limited by the practitioner's responsibilities to another client, a former client, or a third person, or by a personal interest of the practitioner. This definition establishes the threshold at which a practitioner must consider whether a conflict of interest exists.
The Tax Adviser clarifies the procedural consequence when this risk condition is present. It states that if a conflict of interest may exist or may be likely to develop before an engagement is undertaken, the engagement must be declined unless the CPA obtains the informed consent of each client under the conditions set forth under Section 10.29(b). This rule creates a binary choice for the practitioner: either decline the engagement or secure informed consent from every affected client. The phrase "may exist or may be likely to develop" indicates that the risk does not need to be realized or certain; the potential for a conflict is sufficient to trigger the requirement. This applies specifically to practitioners practicing before the IRS, as these rules are part of Circular 230, which governs practice before the Internal Revenue Service.
The consent process: informed consent and written confirmation
Informed consent is the initial step where the client acknowledges the conflict. The written confirmation follows this initial consent. According to Legal Information Institute, the confirmation may be made within a reasonable period after the informed consent, but in no event later than 30 days. This establishes a strict outer limit for the documentation process.
Journal of Accountancy specifies that this written consent must be obtained within a reasonable period after the informed consent, but not later than 30 days after the conflict is known by the practitioner. This phrasing ties the deadline specifically to the point when the practitioner becomes aware of the conflict. It is not a flexible recommendation but a regulatory boundary. The 30-day period is a maximum limit, not a suggested standard for optimal practice. Firms should aim to complete this process as soon as possible after the conflict is identified and the client provides informed consent.
To manage this process effectively, consider the following steps:
- Identify the conflict: Determine the specific conflict of interest as soon as it becomes known.
- Obtain informed consent: Discuss the conflict with the client and secure their informed consent.
- Document in writing: Prepare the written confirmation of the consent.
- Meet the deadline: Ensure the written confirmation is completed within 30 days of the conflict being known.
The written confirmation should clearly state that the client has been informed of the conflict and has consented to the representation. It should also include the date of the informed consent and the date of the written confirmation. This documentation helps establish a clear timeline of events. It provides a record that the practitioner acted within the required timeframe.
Illustrative example: a 30-day written confirmation
A practitioner represents 2 clients before the IRS. On day 1, the practitioner sees a significant risk that duties to 1 client will materially limit the representation of the other. Each client gives informed consent that same day. Written confirmation from each client is finished on day 10, within the 30-day limit. The practitioner keeps both confirmations and can provide them to any IRS officer or employee on request.
A filled reference table for conflict consent requirements
The following table lists the eight proof points for valid conflict of interest waivers, with each row tied to the specific publisher that states the rule.
| Proof Point | Publisher | Requirement Summary |
|---|---|---|
| Prohibition rule | Legal Information Institute | A practitioner shall not represent a client before the Internal Revenue Service if the representation involves a conflict of interest. |
| Risk definition | Legal Information Institute | There is a significant risk that the representation of one or more clients will be materially limited by the practitioner's responsibilities to another client, a former client or a third person, or by a personal interest of the practitioner. |
| Consent requirement | Legal Information Institute | Each affected client waives the conflict of interest and gives informed consent, confirmed in writing by each affected client, at the time the existence of the conflict of interest is known by the practitioner. |
| Confirmation deadline | Legal Information Institute | The confirmation may be made within a reasonable period after the informed consent, but in no event later than 30 days. |
| Retention period | Legal Information Institute | Copies of the written consents must be retained by the practitioner for at least 36 months from the date of the conclusion of the representation of the affected clients. |
| IRS access rule | Legal Information Institute | The written consents must be provided to any officer or employee of the Internal Revenue Service on request. |
| Historical context | The Tax Adviser | In 2002, Section 10.29 was amended to its current form, with additional enhancements in 2007 that included requiring that a known conflict of interest may be waived only by the informed consent of each affected client, confirmed in writing by the client. |
| Decline rule | The Tax Adviser | If a conflict of interest may exist or may be likely to develop before an engagement is undertaken, the engagement must be declined unless the CPA obtains the informed consent of each client under the conditions set forth under Section 10.29(b). |
Retention and IRS access: the 36-month rule
Under the Electronic Code of Federal Regulations, practitioners must retain copies of the written consents for at least 36 months from the date of the conclusion of the representation of the affected clients, according to Legal Information Institute. This specific timeframe applies to the documentation proving that informed consent was obtained for any waived conflicts. The requirement is not tied to the date the consent was signed, but rather to the final day of the representation for the clients involved in the conflict.
The Tax Adviser confirms that Section 10.29(c) requires CPAs and other practitioners to retain these copies for at least 36 months after the date of the conclusion of the representation of the affected clients, according to The Tax Adviser. Practitioners must ensure their file management systems are configured to track the end date of each representation to calculate this retention period accurately. If a firm represents multiple clients in a complex engagement, the retention period is triggered by the conclusion of the representation for the specific affected clients.
Beyond internal retention, there is an external obligation to produce these documents upon request. The Journal of Accountancy notes that a practitioner is required to provide written consents to the IRS on request, according to Journal of Accountancy.
Enforcement and professional responsibility context
The Office of Professional Responsibility (OPR) serves the American public by investigating and disciplining violations of Treasury Department Circular 230 – the Regulations Governing Practice before the Internal Revenue Service – in a manner that fosters confidence in the tax system and compliance with the internal revenue laws, according to Internal Revenue Service. This regulatory framework applies to practitioners who engage with the IRS on taxpayers’ behalf. Circular 230 governs practice before the IRS by setting forth mandatory rules of conduct for tax professionals engaging with the IRS on taxpayers’ behalf, including mainly attorneys, certified public accountants, and enrolled agents, according to Internal Revenue Service.
Enforcement under these rules is active and specific. The IRS states that its enforcement activities include instituting disciplinary proceedings and pursuing sanctions for confirmed violations of the regulations in Circular 230, according to Internal Revenue Service. The scope of these rules is not limited to a single type of professional but covers the primary categories of tax practitioners recognized by the IRS.
Historical context provides insight into the evolution of these conflict of interest rules. The original version of Section 10.29 (essentially unchanged since before 1976) was a simple three-line prohibition against representing clients with conflicting interests except by express consent of all directly interested parties after full disclosure, according to The Tax Adviser. This historical baseline established the core principle that representation with conflicting interests requires express consent. The current regulations build upon this foundation, maintaining the requirement for consent while detailing specific procedural steps for documentation and retention.
