OPINION

_________________

KAREN NELSON MOORE, Circuit Judge. Plaintiffs Dan Carman, Coin Center, 

Raymond Walsh, and Quiet Industries Corp. (“plaintiffs”) regularly transact in cryptocurrency 

for both personal and business matters. They enjoy the privacy and anonymity that 

cryptocurrency transactions provide. So when Congress passed amendments to 26 U.S.C. 

§ 6050I, a law that now requires reporting of certain cryptocurrency transactions to the federal 

government, plaintiffs brought this lawsuit against the United States and the agencies in charge 

of implementing and enforcing § 6050I.1 The district court found that it was without jurisdiction 

to consider the merits of plaintiffs’ constitutional challenges to the amended § 6050I, because 

plaintiffs’ claims are either not ripe for adjudication or because the plaintiffs lack standing. 

Although the district court was correct that one of plaintiffs’ claims is not ripe, several of 

plaintiffs’ claims are justiciable today. Accordingly, we AFFIRM in part and REVERSE in part 

the district court’s judgment, and REMAND for proceedings consistent with this opinion.

I. BACKGROUND

A. Amended 26 U.S.C. § 6050I

Title 26 U.S.C. § 6050I(a) requires “[a]ny person . . . who is engaged in a trade or 

business, and . . . who, in the course of such trade or business, receives more than $10,000 in 

cash” in one or more related transactions to make certain returns to the government. See also R. 

27 (Am. Compl. ¶ 29) (Page ID #262); id. ¶¶ 38–39 (Page ID #264–65) (discussing the concept 

of related transactions). The return must be “in such form as the Secretary [of the Treasury] may 

prescribe” and should contain “the name, address, and [taxpayer identification number] of the 

person from whom the cash was received, . . . the amount of cash received, . . . the date and 

nature of the transaction, and . . . such other information as the Secretary may prescribe.” 

26 U.S.C. § 6050I(b). “Cash received by financial institutions” and cash obtained via a 

1Specifically, plaintiffs have sued the Internal Revenue Service, the Department of the Treasury, and the 

United States, as well as the heads of those agencies and the Attorney General (“defendants”).
No. 23-5662 Carman, et al. v. Yellen, et al. Page 3

transaction that takes place entirely “outside the United States” is not subject to the reporting 

requirements. Id. § 6050I(c).

“Trade or business” has the same meaning in the statute as it does in 26 U.S.C. § 162. 

See 26 C.F.R. § 1.6050I-1(c)(6). Although a flexible concept, as a practical matter “trade or 

business” ordinarily encompasses activity whose “primary purpose” is meant to make “income 

or profit,” as opposed to “[a] sporadic activity, a hobby, or an amusement diversion.” See 

Comm’r v. Groetzinger, 480 U.S. 23, 35 (1987) (“Of course, not every income-producing and 

profit-making endeavor constitutes a trade or business.”); see also R. 27 (Am. Compl. ¶ 32) 

(Page ID #263); 26 C.F.R. § 1.183-2(b) (enumerating relevant factors to consider when deciding 

“whether an activity is engaged in for profit”).

Until recently, cash meant “foreign currency” or “any monetary instrument . . . with a 

face amount of not more than $10,000.” 26 U.S.C. § 6050I(d)(1)–(2); see also R. 27 (Am. 

Compl. ¶ 30) (Page ID #262); 26 C.F.R. § 1.6050I-1(c)(1)(ii). This included “[t]he coin and 

currency of the United States or of any other country” as well as, in certain scenarios, cashier’s 

checks, bank drafts, traveler’s checks, and money orders “having a face amount of not more than 

$10,000.” 26 C.F.R. § 1.6050I-1(c)(ii)(A)–(B). The 2021 Infrastructure Investment and Jobs 

Act, however, amended the definition of “cash” to include “any digital asset.” 26 U.S.C. 

§ 6050I(d)(3); R. 27 (Am. Compl. ¶ 41) (Page ID #265). “Except as otherwise provided by the 

Secretary, the term ‘digital asset’ means any digital representation of value which is recorded on 

a cryptographically secured distributed ledger or any similar technology as specified by the 

Secretary.” 26 U.S.C. § 6045(g)(3)(D); see also R. 27 (Am. Compl. ¶ 42) (Page ID #265).

B. Cryptocurrency

One type of digital asset is cryptocurrency. R. 27 (Am. Compl. ¶ 43) (Page ID #266). 

Cryptocurrency often uses “open-source code,” which allows the public to view, copy, and use 

the code without paying. Id. ¶ 44 (Page ID #266). Plaintiffs allege that a given cryptocurrency 

program relies on “fixed rules of operation designed to facilitate secure and reliable 

transactions.” Id. ¶ 45 (Page ID #266). To engage in transactions using cryptocurrency, users 

must have a “private key” and an “address,” both of which are “random but unique” strings of 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 4

letters and numbers particular to an individual. Id. ¶¶ 46–47 (Page ID #266). To consummate a 

transaction, a receiver of cryptocurrency provides the sender with their unique address. Id. ¶ 48 

(Page ID #266). The sender “digitally signs” with their private key a “transaction message” that 

specifies the amount of cryptocurrency to be sent. Id. ¶¶ 48–49 (Page ID #266).

According to plaintiffs, once this first part of the cryptocurrency transaction is complete, 

“miners” work to “review and validate the transaction message.” Id. ¶ 50 (Page ID #267). 

Through verifying the underlying details of the transaction, such as that the proper private key 

was entered or that the sender has the requisite amount of cryptocurrency to send, miners’ work 

also results in the transaction being listed on a public ledger. Id. ¶¶ 50, 52 (Page ID #267). 

Miners are incentivized to do this verification work because they receive some amount of 

cryptocurrency as a reward. Id. ¶ 51 (Page ID #267).

The hallmarks of cryptocurrency are decentralization and anonymity. Plaintiffs claim 

that miners do not have any personal stake in a given transaction or even know the parties to a 

transaction, and instead miners contribute to the transaction’s completion for the reward of 

cryptocurrency. Id. Likewise, despite the fact that transactions are listed on a public ledger, the 

ledger reveals only the addresses involved in a transaction and the amount of cryptocurrency 

exchanged. Id. ¶¶ 53–55 (Page ID #267–68). Because the addresses themselves do not reveal 

any personal information, the public has little insight into the parties to a transaction. Id.; see 

also id. ¶¶ 67–68 (Page ID #270). If, however, “a user’s personal information is linked to an 

address,” substantial information about the user’s transactions may be uncovered. Id. ¶ 58 (Page 

ID #268). This is so because transactions associated with a given address are listed on the public 

ledger. Id. A user might voluntarily disclose that a given address is theirs in order to facilitate 

transactions with them. Id. ¶ 60 (Page ID #268–69). But a person may be linked to an address 

indirectly if they share details of a given transaction, allowing someone to work backwards from 

the public ledger by locating the transaction and then connecting the address to the user. Id. 

Whether through law-enforcement techniques or otherwise, id. ¶ 61 (Page ID #270), a savvy 

member of the public may also be able to deduce a user’s other addresses and transactions 

through “analyzing the activity of their known addresses,” id. ¶ 69 (Page ID #270–71).
No. 23-5662 Carman, et al. v. Yellen, et al. Page 5

C. The Interaction Between the Amended Reporting Requirements and Cryptocurrency

Under plaintiffs’ view, the amended reporting requirements will require both senders and 

receivers of cryptocurrency to disclose certain information. A sender of more than $10,000 in 

cryptocurrency will need to disclose to the receiver their Social Security Number, name, and 

address. Id. ¶ 94 (Page ID #278). The receiver will need to include this information in the report 

sent to the government. Id. A receiver of cryptocurrency will need to include their own Social 

Security Number, name, and address in the report as well. Id. ¶ 95 (Page ID #278). Along with 

this information, the receiver will need to report the amount of cryptocurrency received, when 

the transaction occurred, and its “nature.” Id. ¶ 96 (Page ID #279) (citation omitted). Finally, 

the receiver will need to include “any other information required by Form 8300,” which is the 

form used to complete the reports. Id. ¶ 97 (Page ID #279); see also 26 C.F.R. § 1.6050I-1(e)(2). 

Although not part of the report, a receiver must also “‘verify the identity’ of the sender” under 26 

C.F.R. § 1.6050I-1(e)(3)(ii), by, for example, examining the sender’s passport or driver’s license. 

Id. ¶ 98 (Page ID #279). In addition to these requirements, receivers of cryptocurrency must 

follow certain procedures. They must sign the report under penalty of perjury and file the report 

within fifteen days of the transaction. Id. ¶ 100 (Page ID #282) (citing 26 C.F.R. § 1.6050I1(e)(1)). Receivers must “furnish to each person whose name is required to be set forth in such 

return a written statement showing” a receiver’s name, address, phone number, and the 

“aggregate amount of cash” received. 26 U.S.C. § 6050I(e); see also R. 27 (Am. Compl. ¶ 102) 

(Page ID #282). And receivers must retain copies of any reports made for five years. 26 C.F.R. 

§ 1.6050I-1(e)(3)(iii); see also R. 27 (Am. Compl. ¶ 103) (Page ID #282).

Plaintiffs harbor serious concerns about being “forced to comply with this entire, 

intrusive process.” R. 27 (Am. Compl. ¶ 105) (Page ID #282). Plaintiffs allege that armed with 

information from reports, the government will be capable of “identify[ing] [transactions] in the 

public ledger.” Id. ¶ 106 (Page ID #283). Once the government has discovered the reported 

transaction on the public ledger, it can “ascertain the addresses of the individuals involved in the 

transaction” and any other transactions completed by those individuals via their addresses 

regardless of whether the individuals were required to report the transactions to the government 

in the first place. Id. ¶ 107 (Page ID #283). For instance, “the government can discover that a 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 6

person donated to a local mosque in 2016, paid for a son’s sobriety treatment in 2018, 

contributed to an unpopular political cause in 2020, and hired a marriage counselor in 2022.” Id.

¶ 108 (Page ID #283). The government already employs certain techniques today, such as hiring 

“public-ledger analysts,” that allow it to connect individuals to certain transactions, to ascertain 

the individuals’ address or addresses, and to discover other transactions in which the individual 

was involved. Id. ¶¶ 109–12 (Page ID #283–84).

Plaintiffs allege more. If the government takes these steps, it will receive “a detailed and 

intimate transaction history” for an individual all without having to obtain a warrant or to act on 

probable cause. Id. ¶¶ 114–15 (Page ID #285). The information may be shared with all levels of 

law enforcement. Id. ¶ 120 (Page ID #286); see also 26 U.S.C. § 6103(l)(15). And because of 

the record-keeping requirements, hackers or other malicious actors may be able to discern 

substantial information about persons subject to the reporting requirements. Id. ¶ 121 (Page ID 

#286). Further, the information that can be gleaned from the reports unveils “activity in which 

[cryptocurrency users] took careful and affirmative steps to preserve their privacy.” Id. ¶ 122 

(Page ID #287). Users will need to “report expressive associations that fall within [the 

requirements’] coverage and they will be required to report commercial activities that, as a result 

of the nature of public ledgers, allow the government to ascertain their unrelated expressive 

activities.” Id. ¶ 124 (Page ID #287). This will lead cryptocurrency users not to engage in such 

expressive activities; some users are already refraining from doing so. Id. ¶ 125 (Page ID #287).

According to the amended complaint, because of the “related” transactions requirements, 

receivers of cryptocurrency will likely need to demand personal identifying information from 

any sender of any amount of cryptocurrency because “there is no natural, common-sense way” 

for a receiver to know that one transaction is unrelated to another. Id. ¶¶ 116–17 (Page ID #285). 

It will be difficult to comply with the law’s verification requirements, because “cryptocurrency 

transactions . . . occur across vast distances and can involve an indeterminate number of 

persons.” Id. ¶ 119 (Page ID #286). The law’s terms also present a compliance problem. For 

example, a receiver who is a miner may not be able to identify the “person” from whom they 

received cryptocurrency, because a miner “is automatically rewarded with new cryptocurrency 

when [they] perform[] mathematically verifiable work to secure the public ledger.” Id. ¶ 126 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 7

(Page ID #287–88). Likewise, individuals will be unable to discern if they are exempt from the 

reporting requirements in the case that a transaction takes place entirely outside the United 

States, because “cryptocurrency transactions are validated and stored on computers all around 

the world.” Id. ¶ 127 (Page ID #288).

Finally, per the amended complaint, the amended § 6050I carries both civil and criminal 

penalties for failing to comply with its requirements. Both senders and receivers of 

cryptocurrency may face felony charges for willfully failing to comply with § 6050I’s 

requirements or for causing another to fail to comply. Id. ¶ 130 (Page ID #289); see also 26 

U.S.C. § 7203 (a willful violation of any provision of § 6050I is a felony). Likewise, receivers 

of cryptocurrency face substantial civil penalties for failing to comply with certain reporting 

requirements. Id. ¶¶ 131–32 (Page ID #290); see also 26 U.S.C. § 6721(e)(2)(C) (receiver who 

intentionally disregards reporting requirements subject to penalty equivalent to the greater of 

$25,000 or the amount of cash received up to $100,000); 26 U.S.C. § 6721(a) (receiver who fails 

to file by required date or fails to include all required information subject to penalty of $250 per 

return).

D. The Plaintiffs

Dan Carman is a lawyer and businessman who lives in Fayette County, Kentucky. Id. 

¶ 134 (Page ID #291). He uses Bitcoin and regularly transacts in it. Id. Carman intends to 

receive cryptocurrency as payment in connection with his work as a Bitcoin consultant. Id. ¶ 136 

(Page ID #291). He alleges that he will receive cryptocurrency payments exceeding $10,000 in 

both single and related transactions involved with this work. Id. Similarly, Carman plans 

personally to mine cryptocurrency and to do so through a company. Id. ¶ 137 (Page ID #291–

92). Beyond receipt of cryptocurrency, Carman also intends to send cryptocurrency to others 

when engaging in certain transactions. Id. ¶ 138 (Page ID #292). He will additionally send 

cryptocurrency to advocacy and religious organizations as part of “advanc[ing] his expressive 

associations.” Id. ¶ 139 (Page ID #292–93).

Carman claims that because he will engage in the types of transactions covered by 

§ 6050I, he will be required to report certain transactions to the government. Id. ¶¶ 140–41 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 8

(Page ID #293). This will in turn lead to the government discovering transactions in which 

Carman has participated through public-ledger analysis; “improper disclosure” of private 

information; and the “uncover[ing] [of] Mr. Carman’s expressive associations.” Id. ¶¶ 143–44, 

146 (Page ID #293–94). Carman is already more reluctant to engage in certain expressive 

activities. Id. ¶ 146 (Page ID #294). Due to the reporting requirements, Carman will incur 

certain compliance costs, including spending time completing reports, tracking transactions 

subject to the reports, and paying accountants and lawyers to assist with the reporting 

requirements. Id. ¶ 145 (Page ID #293–94).

Coin Center is a non-profit organization that “advances the civil liberty interests of 

cryptocurrency users.” Id. ¶¶ 148, 152 (Page ID #294–95). Like Carman, Coin Center alleges 

that it will likely be subject to the reporting requirements because it receives contributions and 

sells sponsorships in connection with its advocacy activities. Id. ¶¶ 149–52 (Page ID #295). As 

a result of the reporting requirements, Coin Center believes that donors will be less likely to 

contribute to its activities and that Coin Center, like Carman, will incur substantial compliance 

costs. Id. ¶¶ 153–54 (Page ID #296).

Raymond Walsh is a software engineer and small businessman who owns plaintiff Quiet 

Industries, a Bitcoin mining company based out of Kentucky. Id. ¶¶ 157, 159 (Page ID #297). 

Walsh often receives Bitcoin payments exceeding $10,000 in connection with his work with 

Quiet Industries. Id. ¶ 160 (Page ID #297–98). In connection with his mining activities, Walsh 

is “rewarded [with cryptocurrency] out of a common pool of assets,” some of which comes from 

other cryptocurrency users and some of which comes from cryptocurrency software. Id. 

Further, Walsh spends more than $10,000 in cryptocurrency in certain transactions in connection 

with his business. Id. ¶¶ 161–62 (Page ID #298). Like the other plaintiffs, Walsh alleges that he 

will incur compliance costs in connection with the new reporting requirements. Id. ¶ 165 (Page 

ID #298–99). Similarly, Walsh fears that the government will be able to connect him to certain 

transactions due to the new reporting requirements. Id. ¶¶ 167–69 (Page ID #299). Quiet 

Industries faces many of the same issues as Walsh. Id. ¶¶ 171–75 (Page ID #300–01).

The government has not foresworn enforcement of the new reporting requirements as to 

any of the plaintiffs. Id. ¶ 179 (Page ID #301). Because related transactions under the new 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 9

requirements can reach back up to one year, some of plaintiffs’ activities may already be subject 

to the law. Id. ¶ 180 (Page ID #302).

E. The Claims

Plaintiffs launch five distinct constitutional attacks on the amended § 6050I, including a 

Fourth Amendment claim, a First Amendment Claim, a Fifth Amendment vagueness claim, an 

enumerated-powers claim, and a Fifth Amendment self-incrimination claim. Id. ¶¶ 184–270 

(Page ID #302–30). For each of these, plaintiffs bring facial challenges, meaning they contend 

all (or almost all) applications of the law are unconstitutional. United States v. Salerno, 481 U.S. 

739, 745 (1987); Johnson v. United States, 576 U.S. 591, 602–03 (2015). That creates some 

confusion, however, because their legal theories, as we note in our analysis, sound in as-applied 

challenges by contending that specific applications of § 6050I or hypothetical future events tied 

to the statute would create constitutional infirmities. See R. 27 (Am. Compl. ¶ ¶ 184–255, 266–

270) (Page ID #302–26, 329–30). Yet, for all claims, plaintiffs’ requested relief is the same: a 

declaration that § 6050I is facially unconstitutional and that enforcement of the law be enjoined. 

Id. at 76 (Page ID #331).

Plaintiffs’ first claim is that the amended § 6050I violates the Fourth Amendment. 

Specifically, plaintiffs claim that the amended law compels senders and receivers of 

cryptocurrency in reported transactions to “share their personal identifying information in 

conjunction with the details of their covered transactions, and thereby reveal sensitive details 

about their personal affairs.” Id. ¶ 190 (Page ID #304). Because of the private nature of 

cryptocurrency transactions, plaintiffs contend that they have a reasonable expectation of privacy 

and that the amended law will invade that expectation of privacy, all without the need for a 

warrant. Id. ¶¶ 189, 192–93 (Page ID #303–04). Plaintiffs additionally claim that the 

government will conduct searches by violating their property rights. Id. ¶¶ 196–201 (Page ID 

#305–07).

Plaintiffs’ First Amendment claim turns on freedom of association. Plaintiffs aver that 

the reporting requirements will “chill protected associational activities” by requiring those who 

wish to remain anonymous to be subject to disclosures and by potentially exposing to retaliatory 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 10

actions by the government those who donate to expressive associations. Id. ¶¶ 221–22 (Page ID 

#312–13). Because the reporting mandate “will require parties to reveal expressive associations 

to the government,” it will “chill and is already chilling protected associational activities in at 

least three ways.” Id. ¶ 229 (Page ID #316). These include allowing the “government to 

ascertain the unrelated expressive associations of parties to all covered transactions” through 

“public-ledger analysis,” id. ¶ 230 (Page ID #316); increasing the likelihood that malicious 

actors like hackers will obtain information and be capable of linking transactions to individuals, 

id. ¶ 231 (Page ID #316–17); and “directly mandat[ing] the reporting of expressive associations,” 

id. ¶ 232 (Page ID #317). Plaintiffs allege that the law is not narrowly tailored and is thus 

unconstitutional. Id. ¶ 236 (Page ID #318).

Plaintiffs’ first Fifth Amendment challenge to the amended § 6050I is a vagueness 

challenge. In essence, plaintiffs argue that the law’s requirements, which were developed in the 

context of face-to-face physical-cash transactions, do not map onto cryptocurrency. Id. ¶ 242 

(Page ID #319–20). Plaintiffs claim that they will face substantial confusion and compliance 

issues with understanding how several of the law’s requirements and definitions comport with 

cryptocurrency transactions. See id. ¶¶ 243–45 (Page ID #320–21) (discussing “person from 

whom the [digital assets were] received”), 246–47 (Page ID #321–22) (similar, with respect to 

“person”), 248–49 (Page ID #322–23) (“receipt”), 250 (Page ID #323) (“entire transaction 

occurs outside the United States”), 251–52 (Page ID #323–24) (“trade or business”), 253 (Page 

ID #324–25) (“structuring” transactions), 254 (Page ID #325) (“verify[ing] the identity” of a 

sender). Given this confusion, plaintiffs allege that § 6050I is unconstitutionally vague. Id.

¶ 255 (Page ID #325–26).

Plaintiffs also claim that Congress has exceeded its enumerated powers by promulgating 

the amended § 6050I. Although Congress may pass laws that are “necessary and proper” to aid 

in executing its powers, id. ¶ 260 (Page ID #327) (quoting U.S. Const., art. I, §8, cl. 18), 

plaintiffs argue that the amended § 6050I is a disproportionate “surveillance” regime that is not 

necessary to carrying out Congress’s taxing powers, id. ¶ 263 (Page ID #328). Plaintiffs 

likewise contend that the law cannot be justified under Congress’s power to regulate interstate 

commerce. Id. ¶ 264 (Page ID #329).
No. 23-5662 Carman, et al. v. Yellen, et al. Page 11

Finally, plaintiffs claim that the amended § 6050I violates the Fifth Amendment because 

it infringes their right against self-incrimination. Plaintiffs acknowledge that the Supreme Court 

has rejected the position that the Fifth Amendment protects against production of any 

incriminating evidence, as opposed to testimony. Id. ¶¶ 267–69 (Page ID #329–30). 

Nonetheless, plaintiffs have brought this claim “to preserve it for further review.” Id. ¶ 268 

(Page ID #330).

F. Procedural Background

Plaintiffs filed a complaint in this case on June 10, 2022, R. 1 (Compl.) (Page ID #1–71) 

and subsequently filed an amended complaint on November 28, 2022, R. 27 (Am. Compl.) (Page 

ID #256–333). On December 12, 2022, defendants moved to dismiss the amended complaint for 

both lack of jurisdiction and for failure to state a claim. R. 29 (Mot. to Dismiss at 1) (Page ID 

#339). Defendants argued that each of the four plaintiffs in this case lacked standing to press 

each of their claims, arguing in effect that all of the plaintiffs’ injuries were either too speculative 

or not cognizable. R. 29-1 (Defs.’ Mem. at 7–19) (Page ID #349–61). Defendants additionally 

contended that several of plaintiffs’ claims, including their Fourth Amendment search claim, 

First Amendment free-association claim, and Fifth Amendment vagueness claim, were not ripe. 

Id. at 19–21 (Page ID #361–63). Finally, defendants argued that all of plaintiffs’ claims failed 

on the merits regardless of any jurisdictional issues. Id. at 21–40 (Page ID #363–82).

Plaintiffs opposed all of defendants’ arguments. R. 32 (Pls.’ Opp.) (Page ID #392–441). 

Plaintiffs claimed that a variety of injuries supported standing for their pre-enforcement 

challenge, including that they are directly subject to the reporting mandate, that they will incur 

compliance costs, that they will be forced to disclose information against their will, that they will 

suffer economic harm, that they will be forced to change their behavior, and that they face a 

credible threat of enforcement should they fail to comply with the reporting mandate. Id. at 11–

18 (Page ID #410–17). Plaintiffs likewise argued that all of their claims are ripe. Id. at 18–20 

(Page ID #417–19). Finally, plaintiffs opposed all of the defendants’ merits arguments. Id. at 

21–40 (Page ID #420–39).
No. 23-5662 Carman, et al. v. Yellen, et al. Page 12

The district court agreed with defendants on justiciability grounds. R. 34 (Op.) (Page ID 

#466–87); Carman v. Yellen, No. CV 5:22-149-KKC, 2023 WL 4636883 (E.D. Ky. July 19, 

2023). The district court first found that plaintiffs’ Fourth Amendment claim was not ripe, 

because the amended § 6050I is not yet effective, the Department of Treasury intended to 

promulgate rules to implement the reporting requirements, and plaintiffs’ apparent theory of 

harm rested on a number of contingent events. R. 34 (Op. at 9–12) (Page ID #474–77). Next, 

the district court found that plaintiffs lacked standing to bring a First Amendment challenge, 

because any potential injuries amounted to nothing more than subjective chill, meaning that the 

injuries were not imminent. Id. at 12–17 (Page ID #477–82). The district court similarly found 

that the First Amendment challenge was not ripe, and that any potential harms or threats of 

enforcement were not concrete or imminent. Id. Turning to vagueness, the district court found 

that the claim was not ripe because the Department of Treasury was still engaged in rulemaking, 

and that a federal court should refrain from interpreting the statute in the first instance before 

final agency action. Id. at 17–18 (Page ID #482–83). The district court found plaintiffs’ 

enumerated-powers claim unripe for the same reasons it found the Fourth Amendment claim 

unripe. Id. at 18–20 (Page ID #483–85). Finally, the district court found that the plaintiffs’ Fifth 

Amendment self-incrimination claim was not ripe, because plaintiffs have yet to assert the right 

against self-incrimination. Id. at 20 (Page ID #485). At the end of its analysis, the district court 

also commented on certain of plaintiffs’ claimed injuries, including harms to their businesses and 

compliance costs. Id. The district court stated that these injuries could not suffice to create 

standing or to overcome the ripeness issues in the case because the injuries are not linked to 

plaintiffs’ claims. Id. at 20–22 (Page ID #485–87). The district court found that this was not the 

case for the enumerated-powers claim but that the claim was nonetheless not ripe and any 

injuries connected to that claim too speculative. Id. at 21 (Page ID #486). Plaintiffs timely filed 

a notice of appeal on July 21, 2023. R. 36 (Not. of Appeal) (Page ID #489–90).

Since plaintiffs filed their appeal, defendants have filed a Rule 28(j) letter, discussing 

Treasury’s and the IRS’s proposed rulemaking regarding the amended § 6050I. DE 24-1 at 1–2. 

The IRS issued “transitional guidance” stating that digital assets need not “be included when 

determining whether cash received in a single transaction (or two or more related transactions) 

meets the reporting threshold” until final regulations pertaining to “application of section 6050I 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 13

to digital assets” are published. Internal Revenue Service, Announcement 2024-4,

II. DISCUSSION

A. Standard of Review

“We review de novo a district court’s grant of a motion to dismiss for lack of subject 

matter jurisdiction.” Kiser v. Reitz, 765 F.3d 601, 606 (6th Cir. 2014). At this juncture, we 

accept the facts as pleaded by the plaintiffs. Id. This includes facts supporting our subjectmatter jurisdiction. Id. The party invoking federal jurisdiction bears the burden of proving that 

we have jurisdiction over a given claim. Id.

B. Standing Generally

The general requirements of standing are familiar. Under Article III of the Constitution, 

federal courts are limited to hearing “Cases” and “Controversies.” U.S. Const. art. III, § 2. To 

ensure that a case or controversy is before a court and to avoid rendering an advisory opinion, 

three basic requirements must be met. See, e.g., Lujan v. Defs. of Wildlife, 504 U.S. 555, 560–61 

(1992). “First, the plaintiff must have suffered an injury in fact—an invasion of a legally 

protected interest which is (a) concrete and particularized and (b) actual or imminent, not 

conjectural or hypothetical.” Id. at 560 (internal quotation marks and citations omitted). 

“Second, there must be a causal connection between the injury and the conduct complained of—

the injury has to be ‘fairly . . . trace[able] to the challenged action of the defendant, and not . . . 

th[e] result [of] the independent action of some third party not before the court.’” Id. at 560–61 

(quoting Simon v. E. Ky. Welfare Rights Org., 426 U.S. 26, 41–42 (1976) (alterations in 

original)). “Third, it must be ‘likely,’ as opposed to merely ‘speculative,’ that the injury will be 

‘redressed by a favorable decision.’” Id. at 561 (quoting Simon, 426 U.S. at 38, 43). “The party 

invoking federal jurisdiction” must establish these elements commensurate with the burden of 

proof required at each stage of a litigation. Id.

Standing is assessed on a claim-by-claim basis and “is not dispensed in gross.” Davis v. 

Fed. Election Comm’n, 554 U.S. 724, 734 (2008) (quoting Lewis v. Casey, 518 U.S. 343, 358 n.6 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 14

(1996)); see also DaimlerChrysler Corp. v. Cuno, 547 U.S. 332, 352 (2006) (discussing cases). 

Even if a plaintiff has standing to press a particular claim or to challenge a particular provision of 

a law deemed to be unlawful, they may lack standing to challenge other provisions of the law 

that have not caused their injury. See, e.g., California v. Texas, 593 U.S. 659, 679 (2021). 

Likewise, if a plaintiff’s injury does not derive from the purportedly unlawful conduct or 

provision, but instead from some other source, a plaintiff will lack standing because the injury 

will not be “fairly traceable to enforcement of the allegedly unlawful provision.” Id. (internal 

quotation marks and citation omitted).

Other hallmarks of the standing analysis are familiar, too. For one, standing should not 

be assessed against the merit (or lack thereof) of a claim. See, e.g., Hicks v. State Farm Fire & 

Cas. Co., 965 F.3d 452, 463 (6th Cir. 2020) (“[O]ne must not confuse weakness on the merits 

with absence of Article III standing.” (quoting Ariz. State Legislature v. Ariz. Indep. 

Redistricting Comm’n, 576 U.S. 787, 800 (2015))). “Although standing in no way depends on 

the merits of the plaintiff’s contention that particular conduct is illegal,” standing “often turns on 

the nature and source of the claim asserted.” Warth v. Seldin, 422 U.S. 490, 500 (1975). 

Second, “establish[ing] standing depends considerably upon whether the plaintiff is himself an 

object of the action (or forgone action) at issue.” Lujan, 504 U.S. at 561. If so, a plaintiff may 

more easily establish an injury in fact and show that the challenged action both causes the injury 

and would be redressed through a favorable judgment. Id. at 561–62; see also Allen v. Wright, 

468 U.S. 737, 757–58 (1984) (explaining that it may be “substantially more difficult to meet the 

minimum requirements of [Article] III” when an injury stems from the actions of a third party 

(internal citation and quotation marks omitted)), abrogated on other grounds by Lexmark Int’l, 

Inc. v. Static Control Components, Inc., 572 U.S. 118 (2014).

Finally, in the preenforcement context, we impose additional requirements to ensure that 

an injury is imminent. We consider whether the party seeking to invoke federal jurisdiction has 

demonstrated (1) “an intention to engage in a course of conduct arguably affected with a 

constitutional interest,” Susan B. Anthony List v. Driehaus, 573 U.S. 149, 161 (2014) (quoting 

Babbitt v. Farm Workers, 442 U.S. 289, 298 (1979)); (2) that their “intended future conduct is 

‘arguably . . . proscribed by [the] statute’” at issue, id. at 162 (quoting Babbitt, 442 U.S. at 298) 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 15

(alterations in original); and (3) that “the threat of future enforcement . . . is substantial,” id. at 

164.

C. Ripeness

“[T]he ripeness doctrine traditionally incorporates both constitutional and prudential 

elements.” Kiser, 765 F.3d at 606. The constitutional elements of ripeness encompass 

traditional parts of the standing inquiry: namely, whether a plaintiff “is threatened with 

‘imminent’ injury in fact.” MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118, 128 n.8 (2007) 

(quoting Lujan, 504 U.S. at 560); accord Susan B. Anthony List, 573 U.S. at 158–59. If a case is 

“dependent on ‘contingent future events that may not occur as anticipated, or indeed may not 

occur at all,’” it is not constitutionally ripe. Trump v. New York, 592 U.S. 125, 131 (2020) (per 

curiam) (quoting Texas v. United States, 523 U.S. 296, 300 (1998)).

On the other hand, prudential ripeness, although closely related, has been called into 

question in recent years. See, e.g., Susan B. Anthony List, 573 U.S. at 167 (commenting on the 

questions surrounding “the continuing vitality of the prudential ripeness doctrine”); Lexmark, 

572 U.S. at 126 (recognizing that prudential standing doctrines are “in some tension with our 

recent reaffirmation of the principle that a federal court’s obligation to hear and decide cases 

within its jurisdiction is virtually unflagging” (internal quotation marks and citations omitted)). 

Nonetheless, this court as well as other circuits have continued applying the doctrine particularly 

when important future intervening events, such as impending regulatory action, will clarify the 

dispute or obviate the need for weighing in on contingencies. See Nat’l Rifle Ass’n of Am. v. 

Magaw, 132 F.3d 272, 291–92 (6th Cir. 1997) (“We believe a federal court should not intervene 

and determine whether a statute enacted by Congress is unconstitutionally vague on its face 

before the agency with rulemaking authority has had an opportunity to interpret the statute.”); 

see also, e.g., Bellion Spirits, LLC v. United States, 7 F.4th 1201, 1209 (D.C. Cir. 2021) 

(considering whether claim was prudentially ripe post-Lexmark, and concluding claim was “fit 

for judicial decision because . . . ‘judicial intervention’ would not ‘inappropriately interfere with 

further administrative action’” (quoting Ohio Forestry Ass’n, Inc. v. Sierra Club, 523 U.S. 726, 

733 (1998))). Prudential ripeness is concerned with (1) whether a claim is fit for judicial review; 

and (2) the hardship to the parties. Kiser, 765 F.3d at 607 & n.2. 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 16

D. Certain of Plaintiffs’ Claims are Not Ripe2

The related doctrines of Article III standing and ripeness are both limits on a federal 

court’s ability to hear a case. Warshak v. United States, 532 F.3d 521, 525 (6th Cir. 2008) (en 

banc) (citing Arizonans for Official English v. Arizona, 520 U.S. 43, 66–67 (1997)). We begin 

our analysis with ripeness. And on this basis, we hold that plaintiffs’ vagueness and selfincrimination claims are not ripe, but that the remainder of their claims are.

The district court resolved many of the issues in this case on ripeness grounds, finding 

that plaintiffs’ Fourth Amendment, R. 34 (Op. at 9–12) (Page ID #474–77), First Amendment, 

id. at 16–17 (Page ID #481–82), Fifth Amendment vagueness, id. at 17–18 (Page ID #482–83), 

enumerated powers, id. at 18–20 (Page ID #483–85), and Fifth Amendment self-incrimination, 

id. at 20 (Page ID #485), claims were all not ripe. The district court appeared to rely principally 

on prudential ripeness factors when deeming these claims not ripe. See, e.g., id. at 12 (Page ID 

#477) (finding that the hardship to plaintiffs is minimal as it relates to the Fourth Amendment 

claim because plaintiffs do not yet need to report their transactions). And the district court 

appeared to suggest that as a general matter no claim can be ripe when a law has yet to go into 

effect. See, e.g., id. at 19 (Page ID #484). Plaintiffs rightly note that most of the district court’s 

findings and defendants’ arguments on ripeness concern prudential, not constitutional, matters. 

Appellants’ Reply at 15. Further, the district court’s view that plaintiffs brought claims too early 

merely because the law is not yet in effect is unsound. See, e.g., Appellants’ Br. at 35 (collecting 

cases). Still, with respect to plaintiffs’ vagueness and self-incrimination challenges, ripeness 

problems abound. 

1. Vagueness

We begin with vagueness. Plaintiffs do not suggest that the amended § 6050I is, on the 

whole, vague. Rather, plaintiffs take issue with myriad provisions of the law and how those 

provisions might apply. The hypothetical nature of this claim is self-evident from plaintiffs’ 

2Although we begin with a discussion of ripeness, plaintiffs would have standing for their claims for 

reasons discussed later in this opinion. We, of course, “have an independent obligation to assure ourselves of our 

own jurisdiction.” Kerchen v. Univ. of Michigan, 100 F.4th 751, 759 (6th Cir. 2024). We begin with ripeness for 

purposes of framing the issues.
No. 23-5662 Carman, et al. v. Yellen, et al. Page 17

amended complaint, and at this juncture it is not fit for our review.3 For example, plaintiffs 

suggest that it is difficult to determine who is a “person from whom the [digital assets were] 

received,” R. 27 (Am. Compl. ¶ 243) (Page ID #320), when it comes to miners, decentralized 

exchanges, and transactions involving numerous users, id. ¶¶ 244–46 (Page ID #320–21). Of 

course, plaintiffs may never engage in these transactions. This confusion would not arise in the 

simple case when one individual transfers cryptocurrency to another individual. Similarly, 

plaintiffs claim that the term “receipt” is vague but allege only one example: a case when a 

sender transfers assets to a “multi-signature” address or to an address controlled by multiple 

people. Id. at ¶ 248 (Page ID #322). As before, plaintiffs do not suggest that an individual-toindividual transaction would create this type of vagueness. In essence, this problem pervades all 

of the plaintiffs’ vagueness allegations. See, e.g., ¶¶ 250 (Page ID #323) (“entire transaction 

occurs outside the United States”), 251–52 (Page ID #323–24) (“trade or business”), 253 (Page 

ID #324–25) (“structuring” transactions), 254 (“verify[ing] the identity” of a sender) (Page ID 

#325). Plaintiffs ask us to evaluate the facial constitutionality of § 6050I against transactions 

that may never occur and that plaintiffs themselves may never undertake. Contra Appellants’ 

Reply at 18 (“Plaintiffs allege that the statute’s requirements are unconstitutional no matter 

what.”).

 Plaintiffs broadly argue that “[f]acial challenges to [laws] are generally ripe the moment 

the challenged [law] is passed.” Appellants’ Br. at 38 (quoting Suitum v. Tahoe Reg’l Plan. 

Agency, 520 U.S. 725, 736 n.10 (1997)). But that discussion in Suitum concerned one specific

type of claim: Fifth Amendment takings claims premised on the theory that mere passage of a 

statute or regulation constitutes a taking. Suitum, 520 U.S. at 736 (“We held that the only issue 

justiciable at that point was whether mere enactment of the statute amounted to a taking.”). The 

quoted footnote clarifies that “[s]uch” challenges are generally ripe the moment a law is passed. 

Id. at 736 n.10 (emphasis added). And plaintiffs’ reliance on Hill v. Snyder, 878 F.3d 193 (6th 

Cir. 2017), is similarly misplaced. Appellants’ Br. 38. Hill concerned facial challenges to a 

sentencing law’s review processes and an alleged denial of rehabilitative programming. 

3We hold that plaintiffs’ vagueness challenge is not fit for review on essentially prudential grounds but 

explain why plaintiffs’ arguments concerning ripeness more generally do not call for a different result.
No. 23-5662 Carman, et al. v. Yellen, et al. Page 18

878 F.3d at 214. The case has nothing to do with vagueness. Instead, Hill reiterates the blackletter proposition that “claims are fit for review if they present ‘purely legal’ issues that ‘will not 

be clarified by further factual development.’” Id. at 213–14 (quoting Thomas v. Union Carbide 

Agric. Prods. Co., 473 U.S. 568, 581 (1985)).

No doubt, facial vagueness challenges are permissible. But Johnson v. United States, 576

U.S. 591 (2015), does not help plaintiffs. Appellants’ Reply at 19. For one, Johnson did not 

raise any standing or ripeness issues: the petitioner was sentenced under the at-issue provision. 

576 U.S. at 595. Here, however, there is considerable uncertainty over whether any of plaintiffs’ 

alleged vagueness issues will come to pass. More basically, the petitioner in Johnson did not 

argue that the law as a whole was void for vagueness but instead contended that the particular 

provision under which he was sentenced was. Id. at 597–98 (speaking only to the residual 

clause). Plaintiffs suggest that their challenge is no different, yet in fact they are merely creating 

hypothetical situations under which myriad separate provisions of § 6050I might be vague.

We cannot invalidate § 6050I based on scenarios that may never come to pass. Nor do 

we have authority to opine generally on its constitutionality. Plaintiffs have not pointed us to a 

case when a preenforcement-facial-vagueness challenge was ripe, presumably because such 

cases benefit from factual development and applications of statutory provisions to particular 

scenarios. Plaintiffs’ pleading makes clear that we would be wading into the world of the 

hypothetical should this claim be allowed to proceed at this juncture. Although it is possible that 

plaintiffs could be ultimately correct that certain provisions of § 6050I could be vague, we do 

not have a constitutional license to issue an advisory opinion on these questions in the abstract.4

Another fact cuts against plaintiffs on this point: pending regulatory action and the 

agency’s moratorium on enforcement until regulations go into effect. Below, both the district 

court and defendants were of the view that mere regulatory uncertainty meant that the case as a 

whole was not ripe. As a general matter, there is no hard rule that such uncertainty or a lapse in 

4As mentioned, this conclusion is reinforced by the fact that plaintiffs bring a facial vagueness challenge to 

the constitutionality of § 6050I, despite relying on hypothetical scenarios that make their claim look like an asapplied challenge. See Johnson v. United States, 576 U.S. 591, 602–03 (2015); United States v. Salerno, 481 U.S. 

739, 745 (1987).
No. 23-5662 Carman, et al. v. Yellen, et al. Page 19

time between when a lawsuit is brought and when a law might take effect render a challenge not 

ripe. See, e.g., Thomas More L. Ctr. v. Obama, 651 F.3d 529, 538 (6th Cir. 2011) (facial 

challenge was ripe despite being brought several years before law was to take effect when there 

was “no reason to think that plaintiffs’ situation will change” and “no reason to think the law will 

change”), abrogated on other grounds by Nat’l Fed’n of Indep. Bus. v. Sebelius, 567 U.S. 519 

(2012); Retail Indus. Leaders Ass’n v. Fielder, 475 F.3d 180, 188 (4th Cir. 2007) (fact that 

regulations had not been promulgated did not render claim unripe because “[r]egulations could 

not alter the [a]ct’s provisions, which clearly establish the healthcare spending and reporting 

requirements that [the plaintiff] claims are invalid” and thus question was “purely legal”). But 

plaintiffs’ cited authority generally adds little to their argument that their vagueness challenge is 

ripe despite pending notice-and-comment rulemaking that may limit § 6050I’s reach or that may 

redress certain of plaintiffs’ concerns (e.g., clarifying how transactions involving miners must be 

reported). Thomas More Law Center concerned purely legal issues: namely, whether Congress 

exceeded its authority under the Commerce Clause or imposed an unconstitutional tax. 651 F.3d 

at 534. Retail Industry Leaders involved similar challenges to whether a state law could even 

exist. 475 F.3d at 185–86 (challenges included ERISA-preemption claim, equal-protection 

claim, and claim under Maryland Constitution).

Try as they might, plaintiffs cannot avoid binding precedent on this point, either. In 

National Rifle Association of America, we considered challenges to the Crime Control Act, a 

federal statute which regulated certain firearms. 132 F.3d at 277–78. The plaintiffs brought 

several claims, including a due-process vagueness claim, an enumerated-powers claim, an equalprotection claim, and certain APA claims. Id. at 278. In an opinion that sounds in both 

constitutional and prudential ripeness concerns, see, e.g., id. at 291, we held that all of the 

plaintiffs’ preenforcement claims were ripe other than their vagueness challenges, id. at 291–93. 

With respect to claims other than the vagueness challenge, we held that the challenges to the 

law’s very passage were ripe because “[t]he statute [could not] be interpreted more narrowly on 

an ‘as applied’ basis in order to avoid these constitutional issues” and “[e]nforcement of the [a]ct 

. . . would not serve to further sharpen or focus their Commerce Clause or Equal Protection 

challenges.” Id. at 291. But the same was not true of the plaintiffs’ vagueness challenge. Id. at 

292–93. Although we did note the since-rejected idea that a vagueness challenge must be as-
No. 23-5662 Carman, et al. v. Yellen, et al. Page 20

applied as opposed to facial, id. at 292, the animating principle for our holding that the 

vagueness claim was not ripe was that “a federal court should not intervene and determine 

whether a statute enacted by Congress is unconstitutionally vague on its face before the agency 

with rulemaking authority has had an opportunity to interpret the statute,” id. Further factual 

development, including regulatory guidance and enforcement actions, would help hone the 

vagueness issues. Id. And more basically, it was clear that “[b]ecause there are possible valid 

applications, a vagueness challenge to” certain provisions of the at-issue statute was not ripe. Id.

at 293.

The same concerns that National Rifle Association discussed with respect to a 

preenforcement-facial-vagueness challenge apply with equal force here. Forthcoming 

regulations may meaningfully narrow § 6050I’s scope, ameliorate certain of plaintiffs’ claimed 

injuries, or result in plaintiffs (or certain of their transactions) not falling under § 6050I’s 

requirements altogether. Regardless, regulations would certainly influence a vagueness 

challenge that hinges on what certain statutory definitions mean and how § 6050I will apply. 

Plaintiffs have no answer for National Rifle Association other than to point to irrelevant factual 

points that do not meaningfully distinguish the case from this one. Appellants’ Reply at 19.

2. Self-incrimination

Only a word is in order with respect to the ripeness of plaintiffs’ Fifth Amendment selfincrimination claim. As a general matter, a Fifth Amendment self-incrimination claim is not ripe 

until a claim of the privilege is actually made. California Bankers Ass’n v. Shultz, 416 U.S. 21, 

72–75 (1974) (holding that self-incrimination claim based on forced reporting not ripe because 

“[w]e cannot, on the basis of supposition that privilege will be claimed and not honored, proceed 

now to adjudicate the constitutionality under the Fifth Amendment” (citation omitted)). No 

claim of privilege has been made, and so plaintiffs’ challenge on this ground is not ripe. 

Plaintiffs’ alternative basis for claiming a violation of this privilege—that any production of 

reports or documents to the government implicates the privilege—is squarely foreclosed by 

binding Supreme Court precedent, and so to the extent plaintiffs press this theory, we dismiss it 

on the merits. United States v. Hubbell, 530 U.S. 27, 34 (2000) (“The word ‘witness’ in the 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 21

constitutional text limits the relevant category of compelled incriminating communications to 

those that are ‘testimonial’ in character.”).

3. Enumerated Powers, Fourth Amendment, and First Amendment

The district court largely repeated its above analyses with respect to plaintiffs’ 

enumerated powers, Fourth Amendment, and First Amendment claims. And on certain points, 

we agree with the district court that plaintiffs appear to rely on contingencies that may never 

come to pass in order either to advance certain legal theories or to bolster their claims. But 

scrutinizing plaintiffs’ claims demonstrates that plaintiffs have ripe claims for purposes of their 

enumerated powers, Fourth Amendment, and First Amendment claims.

Plaintiffs’ enumerated-powers claim is clearly ripe. Neither the district court nor 

defendants realistically suggest that none of the plaintiffs will be subject to § 6050I. And even if 

we do not know the precise contours of how § 6050I will be implemented, what transactions it 

will actually cover, and how many of plaintiffs’ transactions will be at issue, none of these issues 

undermine that the very statute’s existence imposes costs on plaintiffs and subjects them to 

regulations with which they do not wish to comply. The enumerated-powers claim presents an 

exceedingly simple, pure legal issue: either Congress exceeded the powers given to it by the 

Constitution or it did not. No factual development would aid in the disposition of this claim. 

And it was ripe the moment Congress passed the law. Thomas More L. Ctr., 651 F.3d at 538; 

Hill, 878 F.3d at 213–14. Neither the district court nor defendants persuasively suggest 

otherwise. Instead, they seek to recast plaintiffs’ enumerated-powers claim by stating that it is 

coterminous with their Fourth Amendment claim. R. 34 (Op. at 18) (Page ID #483) (“[T]he 

alleged harm arising from this claim is seemingly the Government’s ‘surveillance’ of those 

whose cryptocurrency transactions are disclosed under the amended § 6050I.”). But taking 

plaintiffs’ pleading at face value—that Congress acted ultra vires by promulgating a law that is 

not necessary or proper to carrying out its taxing power—presents a legal question that can be 

resolved today and raises none of the same concerns as plaintiffs’ vagueness challenge.

Plaintiffs’ First and Fourth Amendment claims are not so simple. But for reasons 

discussed in our standing discussion, see infra, the claims are constitutionally ripe. We pause, 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 22

however, to discuss certain issues surrounding these claims with respect to their fitness for 

review. On one read of plaintiffs’ complaint and plaintiffs’ arguments, their Fourth Amendment 

claim would seem not fit for our review. Plaintiffs suggest that the government will undertake 

substantial investigative efforts to connect the transactions they must report to the public ledger, 

then to discern what the plaintiffs’ addresses are, and then to discover a litany of undisclosed 

transactions that may offer insight into the intimate details of plaintiffs’ lives. By undertaking 

this series of actions, the government allegedly will invade the plaintiffs’ Fourth Amendment 

rights. But to explain this Fourth Amendment theory is to demonstrate its issues. See, e.g., Hill, 

878 F.3d at 214 (suggesting that “claims [that] create the risk of entanglement in abstract 

disputes” are not ripe); Doe v. Oberlin Coll., 60 F.4th 345, 356 (6th Cir. 2023) (ripeness issue 

related to selective-enforcement claim cured because “since the filing of the amended complaint, 

we have learned that [college] closed its investigation into the incidents”).5

But plaintiffs have also put forth a Fourth Amendment claim premised on the text of 

§ 6050I that implicates all reporting mandated by this provision. Plaintiffs appear to reframe the 

issue on appeal to suggest that their claim concerns the initial reporting of information to the 

government, not what the government might do with that information down the line. See, e.g., 

Appellants’ Br. at 42. Under this theory, plaintiffs argue that even the mere disclosure of a 

specific transaction to the government implicates the Fourth Amendment bar on unreasonable 

searches regardless of any further steps taken by the government. That is, under this theory the 

initial information transmitted to the government is entitled to Fourth Amendment protection; we 

do not need to look at the mischief that law enforcement could undertake, such as trying to 

discern what plaintiffs’ addresses are. See, e.g., Chandler v. Miller, 520 U.S. 305, 313 (1997) 

(state-mandated drug testing necessary to be qualified to be political candidate was a search); 

City of Los Angeles v. Patel, 576 U.S. 409, 418 (2015) (entertaining facial Fourth Amendment 

challenge to law that required hotel owners to produce registries to law enforcement upon 

demand). As in Chandler and Patel, such a facial Fourth Amendment challenge poses no 

5Again, this theory looks like an as-applied challenge, suggesting that this particular application is 

unconstitutional. If plaintiffs were to succeed on this as an as-applied challenge, their alleged injuries—having to 

comply with the disclosure requirements and pay compliance costs—would not necessarily be redressed. So we 

continue to analyze plaintiffs’ claims as facial challenges, as they request.

reviewability issues because it is premised on solely the disclosures that must actually be made 

based on the text of the statute, not what law enforcement intends to do with the information or 

how the law will be enforced. And such a challenge would seem akin to that addressed by the 

Supreme Court in Shultz concerning the depositor-plaintiffs’ claim that a law requiring them to 

report certain incoming or outgoing foreign-bank transactions to the government violated the 

Fourth Amendment. 416 U.S. at 59–63. Although the Court considered standing issues with 

other claims, this claim premised on the mere disclosure of reports to the government was 

decided on the merits. Id. at 63 (holding that regulations were “reasonable in the light of [their] 

statutory purpose, and consistent with the Fourth Amendment”).

The same is true of the First Amendment claim. One ostensible version of this claim is 

based on a causal chain that may never come to pass: principally, as with the Fourth 

Amendment claim, that the government will undertake efforts to discover substantial information 

about plaintiffs’ expressive activities and associations that is not otherwise self-evident from the 

initial reports. By way of an example, plaintiffs allege that the reporting mandate “will chill 

expressive activity because it will allow the government to ascertain the unrelated expressive 

associations of parties to all covered transactions . . . [through the use of] public-ledger analysis” 

and “will all but guarantee that hackers will be able to access and publicize the information 

contained in §6050I reports.” R. 27 (Am. Compl. ¶¶ 230–31 (Page ID #316–17). As above, 

these claims of First Amendment harm apply only in certain limited circumstances that rest on 

too many contingencies and thus pose reviewability issues.

As with the Fourth Amendment claim, however, a narrower version of the claim appears 

ripe now: that the “reporting mandate will directly mandate the reporting of expressive 

associations.” Id. ¶ 232 (Page ID #317). In essence, under this theory, plaintiffs allege that the 

mere disclosure of transactions to the government impedes their First Amendment associational 

rights, regardless of the government’s decision (or not) to undertake further investigation. 

Because there is no question that at least some of the plaintiffs will need to make § 6050I reports, 

it is appropriate for a court to consider whether the mere disclosure of covered transactions 

implicates the First Amendment and passes the requisite level of constitutional scrutiny if so. 

See, e.g., Gerber v. Herskovitz, 14 F.4th 500, 506–07 (6th Cir. 2021) (distinguishing cases 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 24

premised on “subjective chill” because the plaintiffs were not merely alleging “that general state 

policies or surveillance chilled [their] exercise of free speech”); see also Americans for 

Prosperity Found. v. Bonta, 594 U.S. 595, 606 (2021) (considering First Amendment challenge 

to California’s law requiring charities to disclose names and addresses of donors who contributed 

over $5000) (citing NAACP v. Alabama ex rel. Patterson, 357 U.S. 449, 462 (1958)). Again, at 

this stage, we take no position on whether § 6050I reports in fact implicate the First Amendment 

or address concerns about means–ends tailoring if it does. Instead, we accept at this stage 

plaintiffs’ theory of substantive unconstitutionality: that mere disclosure of the information 

required by § 6050I reports without more implicates plaintiffs’ associational rights. Gerber, 

14 F.4th at 507.

In line with the above, the district court erred by finding that plaintiffs’ enumeratedpowers, Fourth Amendment, and First Amendment claims are not ripe. Although plaintiffs may 

not proceed on the theories that the government may abuse the information it obtains via 

disclosures, which are akin to as-applied challenges based on speculative scenarios, plaintiffs 

also put forth theories that require no further factual development and that appear to raise only 

legal issues stemming from the face of the statute. 

E. Plaintiffs Have Suffered an Injury in Fact for Purposes of Their Ripe Claims

Separate and distinct from any ripeness issues, defendants also claim that plaintiffs have 

failed to plead adequately an injury in fact for all of their claims. Accordingly, we consider if 

plaintiffs’ ripe claims—the enumerated-powers claim, First Amendment claim, and Fourth 

Amendment claim—nonetheless have an injury-in-fact problem. Because plaintiffs have 

pleaded facts showing that they will indeed be subject to the reporting requirements in some 

form or another and pay compliance costs, the district court should have proceeded to the merits 

on these claims.

As with ripeness, plaintiffs’ First and Fourth Amendment claims have much in common 

with respect to injury in fact. Plaintiffs have pleaded that they will engage in at least some

transactions that require § 6050I reports. But they do not wish to make the required disclosures. 

Without even considering plaintiffs’ myriad other pleaded injuries, including compliance costs 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 25

and economic harms, two basic points combine to show that plaintiffs have pleaded an injury in 

fact for their First and Fourth Amendment claims.

First, there is no question that, per the amended complaint’s allegations, at least some of 

the plaintiffs will have to report at least some of their transactions. Although the government 

disputes this, see infra, we know that “[w]hen the suit is one challenging the legality of 

government action or inaction, the nature and extent of facts that must be averred . . . in order to 

establish standing depends considerably upon whether the plaintiff is himself an object of the 

action (or forgone action) at issue.” Lujan, 504 U.S. at 561. When there is no doubt that the 

plaintiff is the direct object of the law, regulation, or government action, “there is ordinarily little 

question that the action or inaction has caused him injury, and that a judgment preventing or 

requiring the action will redress it.” Id. at 561–62.

Plaintiffs’ alleged harm flows from being subject to § 6050I. Indeed in similar cases, 

directly regulated parties had standing to pursue Fourth Amendment, see, e.g., Chandler, 

520 U.S. at 313; Patel, 576 U.S. at 418; Shultz, 416 U.S. at 59–63, and First Amendment claims, 

see, e.g., Davis, 554 U.S. at 733 (explaining that plaintiff had standing to challenge disclosure 

requirement precisely because plaintiff would be “spared [] from making those disclosures” if 

requirement were declared unconstitutional). Under these theories, the very disclosure of the 

information required by § 6050I is injurious, and because plaintiffs have pleaded they will have 

to make the disclosures, they have suffered an injury in fact as the direct objects of the action at 

issue. See, e.g., Food & Drug Admin. v. All. for Hippocratic Med., 602 U.S. 367, 382 (2024) 

(“Government regulations that require or forbid some action by the plaintiff almost invariably 

satisfy both the injury in fact and causation requirements.”); State Nat’l Bank of Big Spring v. 

Lew, 795 F.3d 48, 53 (D.C. Cir. 2015) (“There is no doubt that the Bank is regulated by the 

Bureau. Under Lujan, the Bank therefore has standing to challenge the constitutionality of the 

Bureau.”). Again, Shultz, another disclosure case, proves the point. There was no question that 

the depositor-plaintiffs had standing for their Fourth Amendment claim because it was clear that 

these plaintiffs would be required to report certain income under the relevant statute and 

regulations. Shultz, 416 U.S. at 63. And with respect to the ACLU’s First Amendment 

challenge, the organization lacked standing only because the ACLU failed to plead facts that 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 26

suggested that it would be subject to the reporting requirements, not because having to comply 

with the law as a regulated entity would not constitute an injury. Id. at 76. Plaintiffs allege here 

that they will be subject to § 6050I and that those forced disclosures will harm them.

Plaintiffs have little difficulty demonstrating an injury in fact for purposes of their 

enumerated-powers claim. Although plaintiffs must demonstrate their standing on a claim-byclaim basis, there is no reason why the same injury that provides the plaintiffs with standing to 

bring their First and Fourth Amendment claims—being directly subject to the disclosure 

requirements—would not suffice to create standing for their enumerated-powers claim. See 

State Nat’l Bank, 795 F.3d at 54 (direct regulation theory of injury sufficed when “[t]he Bank is 

not challenging an agency rule that regulates its conduct . . . but rather is challenging the legality 

of the regulating agency itself”). In any event, because this claim is that the statute is void ab 

initio, we see no reason why any of the injuries that plaintiffs identify would not suffice. See, 

e.g., Kentucky v. Yellen, 54 F.4th 325, 342–43 (6th Cir. 2022) (compliance costs met injury-infact requirement for spending-clause violation); Rice v. Village of Johnstown, 30 F.4th 584, 591 

(6th Cir. 2022) (holding that “palpable economic injuries” in the form of “family’s economic 

interest in developing its property” met injury-in-fact requirement for procedural-due-process 

claim (quoting Sierra Club v. Morton, 405 U.S. 727, 733 (1972))).

The district court appears to have recognized this with respect to the enumerated-powers 

claim but still found that plaintiffs lacked standing. The district court’s reasoning is not 

persuasive. First, the district court took plaintiffs’ claim out of context. Rather than looking at 

the claim as pleaded and the injuries tied to the claim, the district court found that “the alleged 

harm arising from this claim is seemingly the Government’s ‘surveillance’ of those whose 

cryptocurrency transactions are disclosed under the amended § 6050I.” R. 34 (Op. at 18) (Page 

ID #483). Although plaintiffs paint a dystopian picture of § 6050I, this claim does not rely on 

the existence of a surveillance regime. And in any event, the injuries asserted for purposes of 

standing are not dependent upon the substantive merit of the claim. With respect to injury, the 

district court simply discounted the allegations in the amended complaint. The district court 

stated that “Plaintiffs never allege that compliance costs and decreased revenues result from [the 

enumerated-powers] claim, instead focusing on the Government’s implementation of a 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 27

surveillance regime.” R. 34 (Op. at 21) (Page ID #486). But plaintiffs’ claim, on the one hand, 

is that Congress could not have constitutionally passed § 6050I, and their asserted injuries on the 

other—costs, compliance, and the like—result from being regulated by the law. Plaintiffs’ 

requested relief—a declaration that § 6050I is unconstitutional and an injunction—would cure 

their pleaded injuries.

Neither the district court’s nor defendants’ other views on the injury-in-fact requirement 

rest on solid ground. The district court found that the plaintiffs could not rely on the plethora of 

injuries that they allege that they will suffer—including being objects of regulation, suffering 

from economic harms, and incurring compliance costs—to create standing for their claims. Id. at 

20–21 (Page ID #485–86). The district court based this overarching finding on Judge 

Batchelder’s lead opinion in American Civil Liberties Union v. National Security Agency, which 

did not garner a majority. See 493 F.3d 644, 648 (6th Cir. 2007) (Lead Op.) (showing that Judge 

Gibbons concurred in only the judgment and that Judge Gilman dissented); id. at 688 (Gibbons, 

J., concurring) (concurring in the judgment because the plaintiffs “failed to provide evidence that 

they are personally subject to” the challenged action, and refusing to “reach the myriad other 

standing and merits issues” discussed by the lead and dissenting opinions). The lead opinion in 

ACLU scrutinized the plaintiffs’ claims and stated that the plaintiffs lacked standing through a 

sort of mixed standing and merits analysis. Id. at 653 (Lead Op.). This was so because, 

according to the lead opinion, “a cause of action is intertwined with an injury.” Id. Yet the lead 

opinion did not cite any cases to support this proposition. And the analysis appears to merge the 

merits and standing inquiry, which the Supreme Court has explicitly held is inappropriate. See 

Davis v. United States, 564 U.S. 229, 249 n.10 (2011); see also, e.g., CHKRS, LLC v. City of 

Dublin, 984 F.3d 483, 489 (6th Cir. 2021) (“[J]ust because a plaintiff’s claim might fail on the 

merits does not deprive the plaintiff of standing to assert it.”) (collecting cases).

Picking up where the district court left off, defendants’ appellate briefing on the standing 

issue is entirely devoted either to problematizing the merits of plaintiffs’ claims or to questioning 

whether the plaintiffs are even subject to the reporting mandate. With respect to the former, 

defendants suggest that in every case that a plaintiff alleges a violation of an individual 

constitutional right, they must initially make a showing that the violation is at a minimum 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 28

“colorable” or “arguable.” Appellees’ Br. at 18; see also CHKRS, 984 F.3d at 489 (“[O]nce the 

plaintiff has alleged a ‘colorable’ or ‘arguable’ claim that the defendant has invaded a legally 

protected interest, the plaintiff has met this element of an Article III injury.”). According to 

defendants, this language in CHKRS imposes some additional initial examination of the merits of 

plaintiffs’ claims as a threshold standing matter. CHKRS, however, is more circumscribed than 

defendants suggest. CHKRS drew this language principally from Steel Company v. Citizens for a 

Better Environment, a case in which the Court addressed an issue of statutory standing in the 

first instance and rejected addressing statutory merits issues prior to examining Article III 

standing. 523 U.S. 83, 92–94 (1998). Steel Company held that a failure of a claim on the merits 

implicates constitutional standing only when a claim “clearly appears to be immaterial and made 

solely for the purpose of obtaining jurisdiction or where such a claim is wholly insubstantial and 

frivolous.” Id. at 89 (quoting Bell v. Hood, 327 U.S. 678, 682–83 (1946)). Steel Company then 

held that it was inappropriate to make this merits-style determination at the outset or to deem 

such an issue “jurisdictional.” Id. at 92–93. In other words, Steel Company rejects the approach 

taken by the defendants in their briefing. See id. at 109–10 (holding that the federal courts 

lacked jurisdiction because “none of the relief sought by respondent would likely remedy its 

alleged injury in fact”).

Similarly, defendants rely on Parsons v. United States Department of Justice to create 

some new rule that constitutional claims require specific types of injury. 801 F.3d 701, 711–13 

(6th Cir. 2015); Appellees’ Br. at 18. But Parsons says no such thing. Instead, Parsons 

examined standing to bring First Amendment, procedural-due-process, and APA claims 

premised on the “chilling effects on [the plaintiffs’] freedoms of speech and association; 

stigmatic reputational injury; and various harms inflicted by third-party law enforcement 

agencies, such as improper stops, detentions, interrogations, searches, denial of employment, and 

interference with contractual relations.” Id. at 711. We then analyzed the plaintiffs’ standing on 

a claim-by-claim basis, and held that the plaintiffs’ reputational and stigmatic injuries coupled 

with allegations of chill met the injury-in-fact requirement for the First Amendment and 

procedural-due-process claims, and that the plaintiffs’ claimed “freedom from placement” on the 

challenged report sufficiently alleged a procedural injury for the plaintiffs’ APA claims. Id. at 

711–13. Nowhere in Parsons did we suggest that only a particular kind of injury could suffice 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 29

to create standing for a particular kind of constitutional claim. Our caselaw shows the opposite 

is true. See, e.g., Rice, 30 F.4th at 591; Yellen, 54 F.4th at 342–43.

The defendants’ next line of attack boils down merely to contesting allegations in the 

amended complaint, which is impermissible at the motion-to-dismiss stage. For instance, 

defendants reach outside the amended complaint to question whether plaintiffs have any privacy 

interests in shielding their transactions, because such transactions are likely already reported on 

income-tax returns. Appellees’ Br. at 22–23. Similarly, the defendants question whether certain 

plaintiffs are subject to the amended § 6050I or whether cryptocurrency transactions are ever 

truly private. Id. at 24–31. But at the motion-to-dismiss stage, we are compelled to treat the 

plaintiffs’ allegations as true. Mosley v. Kohl’s Dep’t Stores, Inc., 942 F.3d 752, 756 (6th Cir. 

2019). Likewise, “general factual allegations of injury resulting from the defendant’s conduct 

may suffice because in considering a motion to dismiss, we presume that general allegations 

embrace those specific facts that are necessary to support the claim.” Id. (quoting Gaylor v. 

Hamilton Crossing CMBS, 582 F. App’x 576, 579 (6th Cir. 2014)) (internal quotation marks 

omitted).

At this juncture, the district court’s and defendants’ approach of disregarding plaintiffs’ 

claimed injuries does not appear appropriate. Nothing in our caselaw suggests that we may 

discount plaintiffs’ claimed injuries at the motion-to-dismiss stage; instead, we must accept what 

plaintiffs have pleaded with respect to their injuries and ask only whether such injuries are 

sufficient to meet the injury-in-fact requirement and accord with the rest of the standing analysis. 

See 13A CHARLES ALAN WRIGHT, ARTHUR R. MILLER, EDWARD H. COOPER, FED. PRAC. & PROC.

JURIS. § 3531.4 (3d ed. 2023) (explaining that “standing can be supported by a very slender reed 

of injury”). So, for example, we accept that, based on plaintiffs’ allegations, they will be subject 

to an unreasonable search by dint of being compelled to make the requisite disclosures to the 

IRS. And we accept at this stage that such disclosures hurt their associational rights.6

6Defendants have additionally invoked, at least in passing, several doctrines that they did not raise below 

and that the district court did not consider. For example, defendants suggest that the zone-of-interests test might 

show that plaintiffs cannot rely on certain injuries for their claims. Appellees’ Br. at 62–63. Further, they argue that 

plaintiffs cannot rely on third-party standing to assert claims. Id. at 63–64. The zone-of-interests test is a prudential 

limit on hearing cases and does not limit our constitutional jurisdiction. See, e.g., Huish Detergents, Inc. v. Warren 
No. 23-5662 Carman, et al. v. Yellen, et al. Page 30

III. CONCLUSION

For the foregoing reasons, we AFFIRM IN PART and REVERSE IN PART the district 

court’s judgment and REMAND for proceedings consistent with this opinion.

County, 214 F.3d 707, 710 (6th Cir. 2000). Given defendants’ failure to raise the doctrine below, we do not 

consider the argument. Although issues of third-party standing of course relate to our subject-matter jurisdiction, 

plaintiffs are not invoking third-party injuries to assert their standing to sue.
