1. What Is an IRS Summons: Authority, Types, and Purpose
IRC 7602 grants the IRS the authority to examine any books, papers, records, or other data that may be relevant or material to an inquiry, to summon any person to appear and produce documents, and to take testimony under oath. This authority underpins virtually every IRS examination and collection enforcement action. A summons is not merely a polite request -- it is a legally enforceable demand backed by federal district court enforcement authority under IRC 7604 (verify at IRS.gov).
The statute distinguishes three contexts in which the IRS may use its summons authority: (1) examining any person liable for tax or required to perform an act under the Internal Revenue Code; (2) examining third parties who may have relevant records -- banks, brokers, employers, accountants, and business associates; and (3) issuing a "John Doe" summons to identify unknown taxpayers who are members of a described group, subject to prior federal district court approval under IRC 7609(f) (verify at IRS.gov).
Summons vs. Information Document Request: Understanding the Escalation
An Information Document Request (IDR) is an informal written request from an examiner for documents during an audit. A taxpayer who declines to respond to an IDR will typically face an escalating series of requests and a deadlines notice before the IRS issues a formal summons. Once a formal summons is issued under IRC 7602, noncompliance can lead to federal district court enforcement proceedings under IRC 7604. The moment a client receives a formal summons -- rather than an IDR -- the representation dynamic changes: qualified legal counsel should be engaged promptly, and a privilege log may need to be prepared before any response is made.
The IRS may issue a summons in three primary enforcement contexts: examination of a return or taxpayer liability (the most common); collection enforcement (including levy and lien actions); and criminal investigation, where a summons may be issued before or after a formal criminal referral to IRS-CI (Criminal Investigation). The context matters: a summons issued in connection with a criminal investigation presents different risks and response strategies than a civil examination summons, and the overlap between civil and criminal investigation creates a set of dual-track problems that practitioners must understand. Verify current IRS summons procedures and contexts at IRS.gov and in current IRC text.
2. The Powell Test: Four Elements for Summons Enforcement
In United States v. Powell, 379 U.S. 48 (1964) (verify current citation and ongoing validity at IRS.gov and through current legal research), the Supreme Court established the four-element standard the IRS must meet to obtain enforcement of a summons in federal district court. Understanding these elements is essential for any practitioner advising a client on whether to challenge or comply with a summons.
The investigation must be for a legitimate purpose -- that is, a genuine inquiry to determine tax liability or collect tax, not to harass the taxpayer or conduct an investigation for an improper purpose such as gathering information for a criminal case after a case has been referred to the DOJ (verify current case law on improper purpose at IRS.gov).
The documents or testimony sought may be relevant to the inquiry. The relevance standard is low -- the IRS need only show that the requested information might throw light on the correctness of the return or the taxpayer's liability. The information need not be admissible in court; it need only be potentially relevant.
The IRS must not already have the information it is seeking. If the IRS has already obtained the same records from another source or from a prior summons, a second summons for the same records may be challenged as not meeting this element. Verify the current application of this element and any exceptions in your circuit at IRS.gov and with legal counsel.
All administrative steps required by the IRC have been followed. This includes proper issuance and service of the summons under IRC 7603, provision of required notices to third parties under IRC 7609, and adherence to any other procedural requirements in the IRC or applicable regulations. Verify all current procedural requirements at IRS.gov before advising a client.
The IRS's burden on the Powell elements is light: a court presumes good faith and the IRS satisfies its initial burden with a simple declaration from the examining agent. Once the IRS makes this prima facie showing, the burden shifts to the summoned party to establish that one or more Powell elements are not met or that a separate defense (privilege, improper purpose, or constitutional grounds) applies. Verify the current allocation of burdens in your circuit at IRS.gov and through current legal research.
Warning: The Powell Burden Shift Creates a Narrow Defense Window -- Don't Wait to Engage Counsel
Because the IRS's initial Powell showing is modest and the burden then shifts to the summoned party, a client who waits until after a show-cause order has been entered -- or who appears at an enforcement hearing without preparation -- typically has little room to successfully challenge enforcement. The grounds for challenging a summons (improper purpose, prior possession, procedural defects, privilege) must be identified and developed before the enforcement proceeding, not during it. Receipt of a summons is a triggering event that requires immediate assessment by qualified legal counsel, not a passive wait-and-see response. Verify the current enforcement timeline and applicable circuit procedures at IRS.gov and through counsel familiar with summons enforcement in your district.
3. Summons to the Taxpayer: Response Obligations and Practical Guidance
When the IRS issues a summons directly to a taxpayer (as opposed to a third party), the taxpayer is required to appear at the time and place specified, produce the records called for, and give testimony under oath. The response to a taxpayer summons involves several distinct obligations that practitioners must track carefully.
3.1 Document Production
The summoned records must be produced in the form specified or in a reasonably accessible format. Before producing any records, the practitioner and client should prepare a privilege log identifying any documents over which the client intends to assert a privilege (attorney-client, work product, IRC 7525 -- with limitations). Documents that are subject to a valid privilege are typically withheld and listed on the privilege log; the log is produced to the IRS instead of the underlying document. Any privilege assertion should be made in consultation with qualified legal counsel, as the scope of each privilege, and the consequences of a failed assertion, are fact-specific (verify current privilege rules at IRS.gov and with counsel).
3.2 Testimony Under Oath
A summoned individual may be required to appear and give testimony under oath. The Fifth Amendment privilege against self-incrimination is available to individual taxpayers in connection with testimony that could tend to incriminate them in a criminal proceeding. However, the Fifth Amendment does not protect all testimony -- only answers that are testimonial and potentially incriminating. The privilege must be invoked specifically for each question, not as a blanket assertion. An entity (corporation, partnership, LLC) cannot invoke the Fifth Amendment through its officers or employees. Verify the current application of the Fifth Amendment in the summons context at IRS.gov and with counsel familiar with criminal tax procedure.
The attorney-client privilege and work product doctrine protect certain communications and documents from disclosure. These privileges are broader than IRC 7525 (the practitioner privilege) and apply in criminal as well as civil proceedings. However, the underlying facts, records, and accounting workpapers held by an accountant are generally not protected from a summons even if the accountant prepared them for or at the direction of a client (Couch v. United States, 409 U.S. 322 (1973); verify current citation and application). Consult qualified legal counsel before making any privilege assertion in response to an IRS summons.
4. Third-Party Summonses Under IRC 7609: Notice Rights and the 20-Day Petition Deadline
When the IRS issues a summons to a third party (a bank, brokerage, accountant, employer, or other recordkeeper) for documents relating to a taxpayer, IRC 7609 requires the IRS to give advance notice to the taxpayer and any other person identified in the summons who may be entitled to notice (verify current notice requirements at IRS.gov and in current IRC text). This notice requirement exists to give the taxpayer an opportunity to assert any applicable defenses or privileges before the records are produced.
4.1 The 23-Day Examination Bar
Under IRC 7609(a)(3) (verify at IRS.gov), the IRS generally cannot examine the records produced by a third party for 23 days following the date the summons is served. This 23-day bar is designed to allow the taxpayer time to receive the notice and take action -- including filing a petition to quash -- before the IRS examines the underlying records.
4.2 The 20-Day Deadline to Petition to Quash
The taxpayer or other notified person has 20 days from the date the summons is served on the third party to file a petition to quash the summons in the appropriate federal district court (IRC 7609(b)(2); verify at IRS.gov). This deadline is absolute -- there are no extensions and the court has no discretion to accept a late petition. Missing the 20-day deadline permanently waives the statutory right to petition to quash.
Warning: The 20-Day Deadline to Quash Is Jurisdictional -- Calendar It Immediately
The 20-day deadline to petition to quash a third-party summons under IRC 7609(b)(2) is jurisdictional and cannot be extended. Count from the date the summons was SERVED ON THE THIRD PARTY -- not the date the client received the notice, which may arrive days later. A client who contacts the practitioner on day 17 after service is already dangerously close to the deadline. Calendar the deadline the moment notice is received. File the petition in the correct federal district court (the district in which the summoned third party resides or is found). Failing to file a timely petition permanently waives any challenge to the summons as to the records sought. Verify the current deadline rules and procedural requirements at IRS.gov and with qualified legal counsel before relying on these dates.
4.3 Grounds to Raise in a Petition to Quash
A petition to quash challenges the validity or enforcement of the summons. Common grounds include: failure to satisfy one or more Powell elements (particularly improper purpose or prior possession of the information); failure to follow required administrative procedures in issuing or serving the summons; the information sought is protected by a privilege (attorney-client, work product, or -- with significant limitations -- IRC 7525); the summons is overbroad or unduly burdensome; or the summons was issued after a criminal referral was made to the DOJ, which courts have recognized as a potential improper-purpose defense (verify the current law on post-referral summonses in your circuit at IRS.gov and through current legal research). The strength of each ground depends heavily on the specific facts and on the current law in the applicable circuit.
5. John Doe Summonses: District Court Approval, Cryptocurrency, and ERC Promoter Enforcement
A John Doe summons (IRC 7609(f); verify at IRS.gov) is a summons directed at a third-party recordkeeper for records relating to an unidentified group of taxpayers. Because no individual taxpayer is named, the normal IRC 7609 notice requirement is inapplicable. Instead, the IRS must obtain prior authorization from a federal district court, which requires the IRS to demonstrate that: (1) the summons relates to the investigation of a particular person or ascertainable group or class of persons; (2) there is a reasonable basis for believing such person or group may fail or may have failed to comply with any internal revenue law provision; and (3) the information sought to be obtained from the examination of the records cannot reasonably be obtained from another source. Verify all current John Doe summons requirements at IRS.gov and in current IRC text.
5.1 Cryptocurrency and Digital Asset Enforcement
The IRS has used John Doe summons authority extensively in the digital asset space. Widely reported examples include summonses directed at cryptocurrency exchanges to obtain account holder information for tax years before exchange-level reporting requirements took effect. Once Form 1099-DA reporting became effective, the IRS's need for John Doe summonses for prospective transactions decreased for reporting brokers; however, pre-reporting-era transaction history and non-broker platforms remain targets. Verify the current status of digital asset summons enforcement priorities at IRS.gov and IRS-CI publications before advising clients with digital asset accounts.
5.2 ERC Promoter Enforcement and the OBBBA Listed-Transaction Designation
The OBBBA (P.L. 119-21, signed July 4, 2025) designated certain ERC claims as "listed transactions" and imposed Material Advisor obligations under IRC 6111 on promoters who assisted with those claims (verify the current scope of the designation and Material Advisor requirements at IRS.gov). A Material Advisor is required to register the listed transaction and maintain a list of clients who participated (verify at IRS.gov). The IRS can access those client lists through formal examination requests or through summonses directed at promoters or their recordkeepers -- potentially including a John Doe summons to reach promoters who have not voluntarily registered or disclosed. Practitioners who assisted clients with ERC claims and who may qualify as Material Advisors should assess their disclosure obligations and potential exposure under IRC 6700/6701 immediately and verify current requirements at IRS.gov.
Caution: ERC Promoter Status May Trigger IRC 6700/6701 Penalties That Dwarf the Summons Itself
For practitioners advising clients on ERC-related summons matters, the summons may be a leading indicator of a broader enforcement action that includes IRC 6700/6701 promoter penalties. The OBBBA increased the IRC 6701 COVID-ERTC Promoter penalty to the greater of $200,000 ($10,000 for individuals) or 75% of gross income derived from ERC-related advice, retroactive to March 12, 2020 (verify current penalty amounts and definitions at IRS.gov). A client who receives a summons in the ERC context may face not only examination of their ERC claims but also promoter-penalty exposure if they advised others on ERC eligibility. Verify current IRC 6700/6701 penalty rules and the Material Advisor disclosure requirements for ERC at IRS.gov before advising any client with ERC involvement.
6. Grounds to Challenge or Quash a Summons
The decision to challenge a summons -- whether through a petition to quash (for a third-party summons) or through objections raised in an enforcement proceeding (for a taxpayer summons) -- requires a careful assessment of available grounds. Challenges that lack factual or legal support waste judicial resources and can damage credibility with the court. The following grounds are the most commonly raised; each requires careful fact-specific analysis before assertion.
6.1 Improper Purpose
A summons issued for an improper purpose -- to harass the taxpayer, to gather information after a criminal referral has been made to the DOJ (see Powell), or to conduct an investigation for a purpose other than determining tax liability -- may be challenged on those grounds. The taxpayer bears the burden of demonstrating improper purpose with specific facts; a general allegation of bad faith is insufficient. Courts in various circuits have addressed the post-referral summons issue with varying results. Verify the current case law in your circuit at IRS.gov and through current legal research before raising an improper purpose defense.
6.2 Prior Possession of the Information
If the IRS already possesses the information it seeks, a summons for the same information does not satisfy the third Powell element. This defense requires specific evidence that the IRS actually has the records -- a declaration or testimony from the IRS agent, a prior production log, or other evidence that the records have already been obtained. Mere suspicion that the IRS might have the records is insufficient.
6.3 Privilege
The attorney-client privilege protects confidential communications between attorney and client made for the purpose of obtaining legal advice. The work product doctrine protects documents and tangible things prepared in anticipation of litigation or for trial. The IRC 7525 privilege protects certain confidential communications with federally authorized tax practitioners (with significant limitations, including the tax shelter exception under IRC 7525(b) and the inapplicability in criminal proceedings). Asserting privilege requires a privilege log identifying each withheld document, the nature of the privilege asserted, and the basis for the assertion. Verify current privilege rules and the requirements for a valid privilege log in your jurisdiction at IRS.gov and with qualified legal counsel.
6.4 Overbreadth and Undue Burden
A summons that seeks an unduly broad category of records -- for example, all documents for a 20-year period when only 3 years are under examination -- may be challenged as overbroad or unduly burdensome. Courts have authority to narrow a summons or modify its scope. The summoned party bears the burden of demonstrating that compliance would be unduly burdensome, typically through evidence of the cost, time, and effort required to produce the records. Verify current overbreadth standards in your circuit with counsel familiar with summons enforcement.
7. Privilege, Kovel Arrangements, and the Tax Shelter Exception
Privilege issues in the IRS summons context require careful analysis because the applicable privileges differ in scope, the rules governing their assertion are fact-specific, and the consequences of a failed assertion (including potential contempt of court or waiver of privilege across related matters) can be severe.
7.1 Attorney-Client Privilege in the Tax Context
The attorney-client privilege protects confidential communications between attorney and client made for the purpose of obtaining legal advice. In the tax context, communications with a tax attorney regarding legal advice on tax positions, audit defense strategy, or representation before the IRS or courts are typically protected -- but only if the communication is confidential and made in the capacity of seeking legal advice (not business advice). Underlying documents and records -- financial statements, bank records, accountant workpapers -- that are transmitted to the attorney do not become privileged simply because the attorney now holds them. Verify the current application of attorney-client privilege in tax matters at IRS.gov and with qualified legal counsel.
7.2 IRC 7525 Practitioner Privilege and Its Limitations
IRC 7525 extends a privilege to confidential communications between taxpayers and federally authorized tax practitioners (enrolled agents, CPAs, enrolled actuaries, enrolled retirement plan agents, and appraisers) to the same extent as attorney-client privilege, but only in federal noncriminal tax proceedings. The IRC 7525 privilege has several critical limitations that distinguish it from attorney-client privilege: (1) it does not apply in criminal tax investigations or proceedings; (2) it does not apply to communications in furtherance of the promotion of a tax shelter (IRC 7525(b)); (3) it does not protect underlying business records and documents (even if the practitioner holds them); and (4) courts have interpreted it narrowly. Verify the current scope, limitations, and circuit-level interpretations of IRC 7525 at IRS.gov and with qualified legal counsel before asserting it in response to a summons.
7.3 Kovel Arrangements
A Kovel arrangement (from United States v. Kovel, 296 F.2d 918 (2d Cir. 1961); verify current citation and application in your circuit) is a structure under which an accountant or other professional is retained by and works under the direction of an attorney to assist in providing legal advice to the client. When properly structured, the Kovel accountant's communications and work product may be protected by the attorney-client privilege and work product doctrine, which are broader than IRC 7525. The key requirements are: the accountant must be hired by and work for the attorney, not the client; the accountant's role must be to assist in the provision of legal advice (not to provide independent accounting services); and the engagement must be documented. Courts scrutinize Kovel arrangements carefully, and not all circuits apply the doctrine identically. Engage qualified legal counsel to structure and document any Kovel arrangement before relying on it for privilege protection in an IRS summons context.
Caution: The Tax Shelter Exception to IRC 7525 Is Broad Enough to Cover ERC-Related Communications
IRC 7525(b) provides that the practitioner privilege does not apply to any written communication between a federally authorized tax practitioner and a client in connection with the promotion of a "tax shelter" within the meaning of IRC 6662(d)(2)(C)(ii) (verify current definition at IRS.gov). The OBBBA designation of certain ERC claims as "listed transactions" raises a significant question: are communications between an ERC promoter and a client in connection with ERC advice excluded from IRC 7525 protection under the tax shelter exception? This is an open question that should be evaluated with qualified legal counsel familiar with both IRC 7525 and the OBBBA ERC listed-transaction framework before asserting IRC 7525 in the ERC context. Do not advise a client that IRC 7525 protects ERC-related communications without a specific and current legal analysis.
8. The Motion to Quash: District Court Procedure and Outcomes
A petition to quash a third-party summons is filed in the federal district court for the district where the summoned third party resides or is found (IRC 7609(h); verify at IRS.gov). The petition must identify the summons, the taxpayer (or person entitled to notice), the grounds for quashing, and the relief requested. The filing of a petition to quash automatically stays the IRS from examining the records until the court rules or the petition is withdrawn.
After the petition is filed, the IRS will file a motion to enforce the summons, typically supported by a declaration from the examining agent establishing the Powell elements. The court will review both filings and may hold a hearing. At the hearing, the taxpayer has the opportunity to present evidence supporting the grounds for quashing; the IRS must rebut any specific factual challenges to the Powell elements or other grounds raised.
The court may: (1) order the summons enforced in full; (2) modify the summons (narrowing the scope of records required); (3) quash the summons entirely; or (4) in cases of privilege disputes, conduct an in camera review of the disputed documents to determine whether the privilege applies. Verify the current procedural rules, timelines, and any local district court requirements at IRS.gov and with counsel before filing a petition to quash.
9. Summons Enforcement Proceedings: Contempt and Cooperation Strategy
If a summoned party refuses to comply with a summons and does not successfully challenge it through the petition-to-quash process, the IRS may seek enforcement through a federal district court proceeding under IRC 7604 (verify at IRS.gov). The IRS petitions the court for an order directing the summoned party to comply, and the court issues a show-cause order. At the show-cause hearing, the IRS makes its prima facie showing; the respondent has the opportunity to raise defenses.
If the court orders compliance and the summoned party continues to refuse, the party may be held in civil contempt. Civil contempt sanctions are designed to coerce compliance, not punish past conduct, and may include daily fines or imprisonment until the party complies. In cases where the court determines that the noncompliance is willful and persistent, criminal contempt is also available. Verify the current contempt standards and sanctions in your district at IRS.gov and with qualified legal counsel.
For most summoned parties, the practical strategy involves: (1) assessing the strength of any available challenges; (2) producing non-privileged records promptly while asserting privilege over protected documents; (3) filing a petition to quash (where available) only if there is a genuine legal basis; and (4) engaging qualified counsel to navigate any enforcement proceedings. Cooperation on legitimate records, paired with assertive privilege claims where appropriate, is generally more effective than blanket noncompliance. Verify current enforcement procedures and best practices at IRS.gov and with counsel familiar with summons enforcement in your jurisdiction.
10. Criminal Investigation and the Dual-Use Problem
IRS-CI (Criminal Investigation) is the law enforcement arm of the IRS. When IRS-CI opens a criminal investigation, it may use summons authority under IRC 7602 to gather evidence, subject to constitutional limitations. The dual-track problem arises when the IRS conducts both a civil examination and a criminal investigation of the same taxpayer, and the civil summons authority is used to gather evidence that may be used in the criminal proceeding.
The Supreme Court has held that the IRS may use its civil summons authority even if it suspects criminal conduct, as long as no formal criminal recommendation (referral to the DOJ) has been made (United States v. LaSalle National Bank, 437 U.S. 298 (1978); verify current citation and application at IRS.gov and through current legal research). Once a case has been referred to the DOJ for prosecution, however, the use of civil summons authority to gather additional evidence for the criminal case may be improper and potentially challengeable. Verify the current law in your circuit on post-referral summonses at IRS.gov and with qualified criminal defense counsel.
Practitioners who receive a summons in the context of an active criminal investigation should immediately engage qualified criminal defense counsel. Statements made to IRS agents during a civil examination conducted before a criminal referral may be used against the taxpayer in a criminal proceeding. The taxpayer's Fifth Amendment rights and any applicable privileges must be carefully evaluated before any response to the summons is made. Verify all current criminal investigation summons procedures and limitations at IRS.gov and with qualified counsel experienced in criminal tax matters.
11. Practitioner Checklist: From Receipt of Summons to Resolution
The following checklist is designed for civil tax practitioners who receive or are advising clients who have received an IRS summons. It is not a substitute for qualified legal counsel in any specific situation. Verify all steps and timelines at IRS.gov and with counsel before advising a client.
- Identify the type of summons (direct taxpayer summons or third-party summons) and the context (civil examination, collection enforcement, or criminal investigation).
- Calendar the 20-day deadline to petition to quash (for third-party summonses); count from the date the summons was served on the third party, not the date the client received notice.
- Identify all persons entitled to notice under IRC 7609 and confirm each has received required notice.
- Assess whether any criminal investigation involvement is indicated (check for IRS-CI agent contact, prior IDRs citing criminal statutes, or formal notification of criminal referral); if so, immediately engage qualified criminal defense counsel.
- Review all documents potentially responsive to the summons; prepare a privilege log for any documents over which privilege is asserted before any production is made.
- Evaluate all available Powell-element challenges: legitimate purpose, relevance, prior possession, administrative steps followed.
- Assess the applicability of attorney-client privilege, work product doctrine, and -- with its significant limitations -- IRC 7525; consult qualified legal counsel before asserting any privilege.
- Determine whether a Kovel arrangement is in place and whether it was properly structured to confer attorney-client privilege protection on accountant communications; verify with counsel.
- For John Doe summonses: determine whether the client is in the described group and whether any procedural challenge is available in district court.
- For ERC-related summonses: assess Material Advisor status under IRC 6111, disclosure obligations, and potential IRC 6700/6701 exposure before advising the client; verify all current ERC enforcement requirements at IRS.gov.
- Coordinate response strategy with legal counsel: identify records to produce, records to withhold with privilege log, and any legal challenges to file.
- Document all actions taken in response to the summons, including dates, persons contacted, records produced, and privileges asserted.

Frequently Asked Questions
What is the Powell test and how does the IRS use it to enforce a summons?
The Powell test (from United States v. Powell, 379 U.S. 48 (1964); verify current citation and application at IRS.gov and in current case law) sets four elements the IRS must establish to obtain court enforcement of a summons: (1) the investigation is conducted for a legitimate purpose; (2) the information sought may be relevant to that purpose; (3) the IRS does not already possess the information sought; and (4) all required administrative steps have been followed. The IRS's burden on these elements is low -- good faith is presumed -- and the burden shifts to the summoned party once the IRS makes a prima facie showing. Verify the current application of the Powell standard in your circuit at IRS.gov and with current legal research before advising a client.
What is the deadline to petition to quash a third-party summons?
Under IRC 7609(b)(2) (verify at IRS.gov and in current IRC text), the taxpayer or other person entitled to notice has 20 days from the date the summons is served on the third party to file a petition to quash in the appropriate federal district court. The IRS generally cannot examine the records for 23 days following service under IRC 7609(a)(3), giving the taxpayer a narrow window to act. The 20-day petition deadline is jurisdictional and has no exceptions or extensions -- missing it permanently waives the statutory right to petition to quash this summons. Verify the current deadline rules, notice requirements, and procedural requirements at IRS.gov and with qualified legal counsel.
Can my client quash a John Doe summons directed at a third party like a crypto exchange?
Typically no, not directly. A John Doe summons is directed at a recordkeeper for an unidentified group; there is no named taxpayer to receive IRC 7609 notice. The district court approval process under IRC 7609(f) (which the IRS must obtain before serving a John Doe summons) is the only procedural protection for unnamed taxpayers before the summons is served. Once records are produced, the IRS may open an individual examination. A motion to suppress evidence in a subsequent Tax Court or district court proceeding is theoretically available on constitutional grounds but faces significant obstacles. Verify all current procedural options with qualified counsel familiar with summons enforcement in your circuit before advising any client on a John Doe summons situation.
Does the IRC 7525 practitioner privilege protect records from an IRS summons?
IRC 7525 (verify current scope at IRS.gov and in current IRC text) protects certain confidential communications between taxpayers and federally authorized tax practitioners to the same extent as attorney-client privilege in federal noncriminal tax proceedings. However, it has significant limitations: (1) it does not apply in criminal proceedings; (2) it does not apply to communications in furtherance of promotion of a tax shelter (IRC 7525(b)); (3) it does not protect underlying documents and records held by the practitioner; and (4) courts have interpreted it narrowly. The ERC listed-transaction designation raises an additional question about whether the tax shelter exception applies to ERC-related communications. Verify all current privilege rules and limitations with qualified legal counsel before asserting IRC 7525 in response to a summons.
What is a Kovel arrangement and how does it affect summons privilege?
A Kovel arrangement (from United States v. Kovel, 296 F.2d 918 (2d Cir. 1961); verify current application in your circuit) is a structure under which an accountant or other non-attorney is retained by and works under the supervision of an attorney to assist in providing legal advice. When properly structured, the accountant's communications and work product may be protected by attorney-client privilege and work product doctrine -- which are broader than IRC 7525 and apply in criminal proceedings. Requirements: the accountant must be hired by and report to the attorney; the purpose must be legal advice. Courts scrutinize Kovel arrangements carefully, and circuit courts apply the doctrine differently. Engage qualified legal counsel to structure any Kovel arrangement before relying on it for summons privilege protection.
What happens if my client ignores or refuses to comply with an IRS summons?
If a summoned party refuses to comply, the IRS may seek enforcement in federal district court under IRC 7604 (verify at IRS.gov). The court issues a show-cause order; if the Powell elements are met and no valid defense exists, the court orders compliance. Continued noncompliance after a court order can result in contempt -- civil (daily fines or imprisonment until compliance) or criminal (if willful). Blanket noncompliance is rarely a viable strategy. The proper approach is to appear, assert valid objections or privileges through counsel, and comply with portions of the summons not properly objected to. Verify all current enforcement procedures and contempt standards at IRS.gov and with qualified legal counsel before advising a client to decline compliance.
How does an IRS summons differ from an Information Document Request?
An Information Document Request (IDR) is an informal request for documents during an examination. Non-compliance with an IDR leads to escalating requests and, ultimately, a formal summons. A formal summons under IRC 7602 is legally enforceable: the summoned party must appear, produce records, and give testimony under oath; noncompliance can lead to federal district court enforcement under IRC 7604. Receiving a summons rather than an IDR signals an escalation -- the examiner has determined informal requests are insufficient, a criminal referral may be present, or a third party's records are needed.

Does the ERC listed-transaction designation mean the IRS can summons ERC promoter client lists?
The OBBBA (P.L. 119-21, July 4, 2025) designated certain ERC claims as listed transactions and imposed Material Advisor obligations (IRC 6111; verify at IRS.gov). Material Advisors must register the listed transaction and maintain client lists. The IRS has broad IRC 7602 and IRC 7609(f) authority to seek those lists through summonses -- including John Doe summonses directed at promoters or their recordkeepers. Prior IRS use of John Doe summonses against cryptocurrency exchanges demonstrates that this mechanism works. ERC practitioners who may qualify as Material Advisors should immediately assess their disclosure obligations and potential IRC 6700/6701 promoter-penalty exposure. Verify all current ERC enforcement requirements, Material Advisor definitions, and disclosure deadlines at IRS.gov before advising any client with ERC involvement.
