Most crypto audits run on Information Document Requests. You get a Form 4564, you produce records, the examiner reviews them. Cooperation is voluntary in the sense that the IDR itself has no teeth.

A summons is different. It is a legal demand, issued under IRC 7602, to appear, testify and produce records. If you ignore it, the IRS can ask a federal court to order compliance. If you are holding one about your crypto, this is how it works.

The authority

IRC 7602(a) authorizes the IRS, for the purpose of ascertaining the correctness of any return, making a return where none has been made, determining any person’s tax liability, or collecting it, to:

  • examine any books, papers, records or other data which may be relevant or material to the inquiry;
  • summon the person liable for tax, or any person having possession, custody or care of books of account relating to that person’s business, or any other person the IRS deems proper, to appear, produce records and give testimony under oath; and
  • take testimony under oath.

IRC 7602(b) says the purposes may include “inquiring into any offense connected with the administration or enforcement of the internal revenue laws.” A summons can serve a civil exam with a criminal dimension.

When it is served on you, not a third party

The third-party summons rules in IRC 7609, with notice to the taxpayer and a 20-day right to petition to quash, do not apply to a summons served on the person whose liability is being investigated. IRC 7609(c)(2)(A) excludes any summons “served on the person with respect to whose liability the summons is issued.”

That means no quash petition. Your route to contest a summons served on you is generally in the enforcement proceeding, if the IRS brings one.

How courts enforce it: the Powell test

The Supreme Court set the standard in United States v. Powell, 379 U.S. 48 (1964). The IRS does not need probable cause. To get enforcement, it must show that the investigation will be conducted pursuant to a legitimate purpose, that the inquiry may be relevant to that purpose, that the information sought is not already in the IRS’s possession, and that the administrative steps required by the Code have been followed.

Once the IRS makes that showing, the taxpayer may challenge the summons “on any appropriate ground,” but the burden of showing an abuse of the court’s process is on the taxpayer. The Court gave examples of abuse: a summons issued for an improper purpose, such as to harass the taxpayer, to pressure a settlement of a collateral dispute, or for any other purpose reflecting on the good faith of the investigation.

Powell also held that the IRS need not show probable cause of fraud to reopen a year that is otherwise closed except for fraud. That matters for old crypto years. See how far back the IRS can audit crypto.

What a crypto summons usually seeks

Expect it to look like the IDR you did not answer, now with a date and place: exchange statements and transaction histories, wallet addresses, basis records, bank records tied to crypto purchases and sales, and testimony about your accounts. In LB&I exams, the IRM requires a delinquency notice and a pre-summons letter before a summons for unanswered IDRs. See IRM 4.46.4.7.3 and the crypto IDR guide.

The criminal line: IRC 7602(d)

IRC 7602(d) says no summons may be issued, and the IRS may not begin an enforcement action, with respect to any person if a Justice Department referral is in effect for that person. A referral is in effect if the IRS has recommended a grand jury investigation or criminal prosecution, or has requested certain return information disclosures for that purpose.

In other words, once a case formally goes to the Justice Department for criminal handling, the civil summons tool turns off for that person. That does not make you safer. It means the investigation has moved to a forum with grand jury subpoenas instead.

Why a summons is the moment to call a lawyer

I tell every client the same thing. If you are holding an IRS summons about your own crypto, do not respond, do not call the agent, and do not produce anything until a lawyer has read it. Here is why.

  • Testimony is under oath. IRC 7602(a)(3) authorizes the IRS to take your testimony under oath. What you say becomes evidence.
  • The purpose may include an offense inquiry. IRC 7602(b) says so expressly. A lawyer needs to assess whether there is criminal exposure before you speak or produce.
  • Privilege questions are case-specific. Whether any constitutional or attorney-client privilege applies to particular records or testimony depends on facts a lawyer has to evaluate. Do not guess.
  • Your production defines the case. Records produced under summons are the record. Errors in them are hard to walk back.

What not to do

Do not destroy, alter or hide records after a summons, or before one. IRC 7206(5) makes it a felony, in connection with an offer in compromise or closing agreement, to withhold, destroy, mutilate or falsify records relating to a taxpayer’s financial condition. The IRS fraud handbook lists “submission of altered or false digital asset records” and “intentional failure/refusal to provide complete digital asset records/information … after repetitive requests” among indicators of fraud. See IRM 25.1.2.11.1.

Do not move assets to frustrate the inquiry. The same handbook lists “conversion of physical assets to digital assets in anticipation of, or in response to, IRS actions” and chain hopping to obscure the source of assets.

Do not ignore it. A summons you ignore becomes a court case you have to answer.

And do not assume the summons is a bluff. The Supreme Court set a low bar for enforcement in 1964, and it has not raised it since. The IRS does not need to prove you did anything wrong to get the records. It needs to show a legitimate purpose and possible relevance.

IDR versus summons, side by side

The two documents often ask for the same things. The consequences are different.

  • Legal force. An IDR is a request. A summons is a legal demand under IRC 7602 that a court can enforce.
  • Testimony. An IDR asks for documents and answers. A summons can require you to appear and testify under oath.
  • What happens if you ignore it. An unanswered IDR leads to delinquency notices and, in LB&I exams, a pre-summons letter. An ignored summons can lead to an enforcement proceeding in federal district court, where Powell sets the standard.
  • How to challenge it. You can negotiate the scope of an IDR with the examiner. For a summons served on you, challenges are generally raised in the enforcement proceeding, and the burden of showing abuse is on you.

If your exam has reached the summons stage, the relationship with the examiner has changed. Your response should change with it.

One more difference worth knowing. Courts enforce IRS summonses through their general power to compel compliance with administrative process. In Powell, the Supreme Court treated the enforcement proceeding as brought under IRC 7402(b) and 7604(a), each of which gives district courts power to enforce IRS summonses “by appropriate process.” A summons that reaches that stage is a lawsuit with your name on it.

The bottom line

A summons is the IRS saying cooperation is no longer optional. The law gives the government a low bar to enforce it and gives you narrow grounds to fight it. Your leverage is in how you respond, not whether. Get counsel before the date on the summons, not after.
