The Limits on IRS Summons Power: What the Code Does Not Allow

IRC 7602(a) lets the IRS summon "any other person the Secretary may deem proper" to produce records and testify. The Supreme Court in United States v. Powell, 379 U.S. 48 (1964), held the IRS does not need probable cause to enforce a summons. That is a lot of power.

But the same chapter of the Code contains limits, and so does the Internal Revenue Manual. Some are absolute bars. Some are procedural conditions. Each one is a possible defense in an enforcement proceeding, as explained in summons enforcement and the Powell standards.

1. No summons after a Justice Department referral

IRC 7602(d)(1) says no summons may be issued, and the IRS may not begin an action under IRC 7604 to enforce one, with respect to any person while a Justice Department referral is in effect for that person.

Under IRC 7602(d)(2), a referral is in effect if the IRS has recommended a grand jury investigation or criminal prosecution of the person to the Attorney General, or if a request has been made under IRC 6103(h)(3)(B) for the person's return information. It ends when the Attorney General notifies the IRS in writing that it will not prosecute, will not authorize or will discontinue a grand jury investigation, or when a final disposition is made in the criminal proceeding.

IRC 7602(d)(3) treats each taxable period, and each tax imposed by a separate chapter, separately. The logic is straightforward: once the government is pursuing a criminal case through the Justice Department, it must use the tools of a criminal case, such as grand jury subpoenas, not the IRS's administrative summons.

2. No unnecessary examinations, and one inspection per year

IRC 7605(b) says no taxpayer shall be subjected to unnecessary examination or investigation, and only one inspection of a taxpayer's books of account shall be made for each taxable year, unless the taxpayer requests otherwise or the IRS, after investigation, notifies the taxpayer in writing that an additional inspection is necessary.

Powell limited how far this goes. The Court said necessity does not mean probable cause, and that the IRS meets the requirement by having a superior determine a further examination is necessary and notifying the taxpayer in writing.

IRM 5.17.6.8 adds that an examination of books to collect a tax, after an earlier examination to determine it, is treated as a new investigation not subject to this restriction. And IRM 25.5.10.3 notes the rule does not apply when already-inspected records are needed for an audit of a different tax year. Where the rule does apply, a second look at the same year without the written notice is a real procedural defect.

3. Advance notice before third-party contacts

IRC 7602(c)(1) generally bars IRS employees from contacting third parties about determining or collecting your tax unless the IRS has notified you at least 45 days in advance that contacts may occur during a stated period of no more than one year. IRC 7602(c)(2) requires the IRS to give you a record of persons contacted, periodically and on request.

Exceptions in IRC 7602(c)(3) cover contacts you authorize, cases where the IRS determines for good cause that notice would jeopardize collection or involve reprisal, and pending criminal investigations. IRM 5.17.6.7 treats service of a summons on a third party as a third-party contact and tells revenue officers to verify the advance notice was given first.

4. Timing, service and description

Several basic requirements are easy to overlook and easy to check:

• Appearance date: at least 10 days from the date of the summons, at a reasonable time and place, under IRC 7605(a).
• Service: in hand or left at the person's last and usual place of abode under IRC 7603(a), with mail service allowed only for listed third-party recordkeepers under IRC 7603(b).
• Description: records described with reasonable certainty under IRC 7603(a).
• Third-party notice: within 3 days of service and at least 23 days before the examination date, when IRC 7609(a) applies.
• Authority: issued by an IRS employee with delegated authority. IRM 25.5.10.3 lists a summons not issued by a properly delegated official as one the IRS should not refer for enforcement.

The notice and quash procedure is covered in third-party summonses.

5. Only IRS employees may question summoned witnesses

Since the Taxpayer First Act in 2019, IRC 7602(f) limits who may take summoned testimony. It says no person other than an officer or employee of the IRS or the Office of Chief Counsel may, on behalf of the Secretary, question a witness under oath whose testimony was obtained under section 7602. It also bars the IRS from passing summoned records to outside contractors under IRC 6103(n) except when the contractor needs them solely to provide evaluation and assistance to the IRS.

If someone who is not an IRS or Chief Counsel employee is asking the questions at a summoned interview, that is worth raising immediately.

6. No levy on the appearance day

IRC 6331(g) bars a levy on a person's property on any day the person, or the person's officer or employee, is required to appear in response to a summons issued to collect tax, unless collection is in jeopardy. It is a small protection, but it means a collection summons cannot be used to bring you in so assets can be grabbed the same day.

7. John Doe summonses need a judge first

A summons that does not identify the person whose liability is being investigated, called a John Doe summons, may be served only after a court proceeding under IRC 7609(f). The IRS must establish that the summons relates to a particular person or ascertainable group, that there is a reasonable basis to believe they may have failed to comply with the tax law, and that the information is not readily available elsewhere. Since 2019, the statute also requires that the information sought be narrowly tailored to the suspected noncompliance. These summonses are typically aimed at groups, not individuals, so this page mentions them only for completeness.

8. Privileges and the Fifth Amendment

Privileged communications cannot be obtained by summons. IRM 25.5.5.4.3 lists the attorney-client privilege, the federally authorized tax practitioner privilege under IRC 7525 in noncriminal tax matters, and the spousal, clergy and psychotherapist privileges. The Fifth Amendment may protect against compelled testimony, and in some cases against the act of producing records, but not for corporations or other collective entities.

Privileges must be asserted specifically, and the summoned person bears the burden of establishing them. Blanket refusals do not work.

9. The bankruptcy automatic stay

IRM 5.17.6.23 says the Office of Chief Counsel has determined that serving a collection summons is an act to collect and should not be done while the bankruptcy automatic stay is in effect. Summonses to determine liability, such as delinquent return or trust fund penalty investigations, are treated differently.

10. Abuse of the court's process

The last limit is the broadest and the hardest to use. Powell said a court may not permit its process to be abused, and that abuse would occur if a summons were issued for an improper purpose, such as to harass the taxpayer, to put pressure on the taxpayer to settle a collateral dispute, or for any other purpose reflecting on the good faith of the particular investigation.

The burden of showing abuse is on the taxpayer, and Powell said it is not met merely by showing that the ordinary limitations period has run or that the records were examined before. In practice, abuse arguments succeed only with concrete facts about purpose and timing, which is another reason to keep careful records of every contact with the IRS.

What the limits do not do

None of these limits let you avoid a properly issued summons because the questions are uncomfortable or the records are inconvenient to gather. Courts enforce valid summonses. And fighting a summons can have costs: under IRC 7609(e), a taxpayer's proceeding to quash a third-party summons suspends the assessment and criminal limitations periods while it is pending.

The right approach is to check each limit against your facts, raise the real ones early and in writing, and comply with the rest.
