Petitioner-appellant Gurmeet Singh Dhinsa appeals from a judgment entered in the United States District Court for the Eastern District of New York (Edward R. Korman, Judge ) denying his petition for a writ of habeas corpus. Dhinsa claims that he is entitled to bring a petition under 28 U.S.C. § 2241 because the standard remedies under 28 U.S.C. § 2255 are "inadequate or ineffective to test the legality of his detention," thereby entitling him to invoke the "savings clause" codified in 28 U.S.C. § 2255(e).
In 1999, a jury convicted Dhinsa on numerous counts arising out of his leadership role in an extensive racketeering enterprise, including two counts of murdering a potential witness or informant in violation of 18 U.S.C. § 1512(a)(1)(C) ("informant murder").1 He is now serving six concurrent life sentences, including a life term on each count of informant murder. In his habeas petition, he challenges only those two convictions, and so the relief he seeks would not affect the length of his incarceration. This circumstance raises the question whether he has standing to maintain his petition. We conclude that he does, in light of the $100 special assessment that attaches to each of the challenged convictions. If Dhinsa's challenge is successful as to either conviction, he may be entitled to vacatur of the corresponding sentence, including the special assessment. Although the special assessments are slight in amount, we think that each is a concrete, redressable injury sufficient to establish Dhinsa's Article III standing to challenge these two convictions.
Having confirmed Dhinsa's constitutional standing to assert the petition, we next consider whether Dhinsa is entitled to bring a § 2241 habeas petition under the § 2255(e) savings clause. A petitioner who invokes the savings clause must demonstrate, on the existing record, that he is innocent of the crime of conviction under a *74legal theory that was not previously available to him. Here, Dhinsa asserts that he is innocent of both counts of informant murder under the Supreme Court's decision in Fowler v. United States , 563 U.S. 668, 131 S.Ct. 2045, 179 L.Ed.2d 1099 (2011), which requires the prosecution to show that the murder victim was "reasonably likely" to have communicated with a federal official. Id. at 678, 131 S.Ct. 2045. We conclude that, on the existing record, Dhinsa has failed to make the threshold showing of innocence. He ordered the killing of the two victims after they began investigating his multi-year, multimillion-dollar racketeering enterprise, through which Dhinsa committed acts of violence, fraud, and bribery. Racketeering enterprises of this nature are commonly investigated and prosecuted by federal officials. Thus, a juror could reasonably find that each of Dhinsa's victims was "reasonably likely" to have communicated with federal officials had Dhinsa not ordered him killed. The District Court was thus correct to conclude that Dhinsa has failed to make the required threshold showing under § 2255(e). This threshold test is jurisdictional, however, and so the District Court erred insofar as it entered a judgment denying the petition on the merits. Accordingly, we VACATE that portion of the judgment and REMAND the case with instructions for the District Court to enter a judgment dismissing the petition for lack of jurisdiction.
BACKGROUND
I. Dhinsa's criminal trial and direct appeal
In 1999, a jury convicted Dhinsa on twenty-one counts arising out of Dhinsa's role in a racketeering enterprise. The evidence adduced during Dhinsa's four-month trial before the District Court is described at length in this Court's opinion ruling on his multi-faceted direct appeal. See United States v. Dhinsa ("Dhinsa I "), 243 F.3d 635 (2d Cir. 2001). We set forth those facts here only as necessary to understand and resolve the instant appeal.2
Dhinsa was indicted on twenty-nine counts in connection with his role as "the self-professed leader of the 'Singh Enterprise,' a vast racketeering organization built around a chain of fifty-one gasoline stations that Dhinsa owned and operated throughout the New York City metropolitan area under the name 'Citygas.' " Id. at 643. Dhinsa installed "pump-rigging" technology that overcharged consumers for gas, generating tens of millions of dollars of excess revenues over a period of a decade. Id. He protected the enterprise by bribing public officials, purchasing weapons, and threatening, kidnapping, or murdering individuals whom he viewed as threats to his operations. Id. at 643-46.
The convictions at issue in this appeal arise out of the 1997 killings of Manmohan Singh ("Manmohan") and Satinderjit Singh ("Satinderjit"), each of whom was "murdered on Dhinsa's orders" after they began independently questioning the activities of the Singh Enterprise. Id. at 643. As we found when this case was last before us:
Prior to his death, Manmohan made numerous inquiries, and confronted various members of the Singh Enterprise, about the July 1995 disappearance of his *75brother Kulwant, a Citygas employee. Dhinsa ordered Satinderjit murdered after learning that he was cooperating with police regarding, inter alia, Kulwant's disappearance, Manmohan's murder, and the enterprise's pump-rigging scheme.
Id. The jury convicted Dhinsa on multiple counts in connection with these murders, including two counts of informant murder (because of Manmohan and Satinderjit's "active or potential cooperation with the police"), along with two counts of murder in aid of racketeering and two counts of conspiracy to murder in aid of racketeering, in violation of 18 U.S.C. §§ 1959(a)(1), (5). Id. at 644. Overall, the jury convicted Dhinsa on twenty-one of the twenty-nine counts in the superseding indictment. Id. at 642. On appeal, we vacated three of Dhinsa's convictions and affirmed the remaining eighteen, including all convictions on the counts arising out of the murders of Manmohan and Satinderjit. Id. at 677-78.
Dhinsa's incarceratory sentence, as adjusted after the appeal, consists of six concurrent terms of life imprisonment-four of which arise out of his convictions for informant murder and murder in aid of racketeering in connection with the murders of Manmohan and Satinderjit-plus several lesser concurrent and consecutive sentences of varying lengths. The District Court also imposed financial penalties, including a statutorily mandated special assessment of $50 to $100 for each count of conviction. See 18 U.S.C. § 3013(a) (specifying the amount of money courts "shall assess on any person convicted of an offense against the United States").
II. Collateral proceedings
In 2002, after Dhinsa's convictions became final, he filed two habeas petitions asserting claims of ineffective assistance of counsel: a petition under 28 U.S.C. § 2241 in the Central District of California, where he was then incarcerated, and a motion to vacate his sentence under 28 U.S.C. § 2255 in the District Court in the Eastern District of New York. Both petitions were rejected on procedural grounds.
In May 2012, Dhinsa filed a new § 2241 habeas petition asserting that he is innocent of both counts of informant murder under the standard articulated in the Supreme Court's 2011 decision in Fowler .3 The District Court transferred the § 2241 petition to this Court for possible certification as a second or successive § 2255 motion under 28 U.S.C. § 2255(h). In May 2013, a motions panel concluded that Dhinsa's motion did not qualify as a successive § 2255 motion. The Court remanded, however, with instructions for the District Court to consider: (1) whether Dhinsa is entitled to file a § 2241 petition via the savings clause in § 2255(e), and if so, (2) whether Dhinsa is entitled to relief under § 2241.
On remand, after the parties filed briefs addressing those two questions, the District Court requested additional briefing on the so-called "concurrent sentence" doctrine, under which "an appellate court affirming a conviction and sentence" may, *76in its discretion, choose "not [to] hear a challenge to a conviction on another count if [that second conviction] carries a sentence that is equal to or less than the affirmed conviction." Concurrent-Sentence Doctrine , Black's Law Dictionary (10th ed. 2014); see generally United States v. Vargas , 615 F.2d 952, 956-60 (2d Cir. 1980). In response, Dhinsa acknowledged that even if he receives all the relief sought in his habeas petition, he will remain incarcerated pursuant to his four additional concurrent life sentences.
On March 2, 2017, the District Court issued an order denying Dhinsa's petition. Dhinsa v. Krueger (" Habeas Order "), 238 F.Supp.3d 421 (E.D.N.Y. 2017). The District Court concluded, first, that the petition should be dismissed under the concurrent sentence doctrine because Dhinsa had not identified any meaningful collateral consequences arising specifically out of the two challenged convictions. Id. at 427-33. In conducting that analysis, the District Court cited extensively to cases discussing subject matter jurisdiction and Article III standing, but did not expressly articulate any jurisdictional conclusions regarding this case. Next, the District Court responded to the questions posted in this Court's mandate and concluded that Dhinsa is neither eligible to file a § 2241 petition nor entitled to any habeas relief. Id. at 433-38. The court entered a judgment denying the petition, but issued a certificate of appealability on all issues. Dhinsa timely appealed.
DISCUSSION
We review de novo the District Court's conclusions of law as to both subject matter jurisdiction and the merits of Dhinsa's § 2241 habeas petition. Adams v. United States , 372 F.3d 132, 134 (2d Cir. 2004). The District Court's analysis raises questions as to Dhinsa's Article III standing, and so we begin by assuring ourselves that Dhinsa has standing to bring the petition. We next conclude, however, that Dhinsa is not entitled to pursue a § 2241 habeas petition via the savings clause in § 2255(e), and that the District Court therefore lacked jurisdiction over the petition. On the existing record, a juror could reasonably conclude, as required under Fowler v. United States , 563 U.S. at 678, 131 S.Ct. 2045 (2011), that each of Dhinsa's victims was "reasonably likely" to communicate with a federal official had he not been murdered. The District Court reached a similar conclusion, but entered a judgment denying the petition on the merits. We therefore vacate that portion of the judgment and remand for entry of an amended judgment dismissing the petition for lack of jurisdiction. Because we resolve Dhinsa's appeal on jurisdictional grounds, we need not consider the government's invitation to dispose of the case under the discretionary concurrent sentence doctrine.4 Cf. Tavarez v. Larkin , 814 F.3d 644, 648 (2d Cir. 2016).
I. Article III standing
The District Court concluded that Dhinsa's petition should be dismissed *77under the concurrent sentence doctrine, but the court's reasoning was consistent with a conclusion that Dhinsa lacked Article III standing to assert the petition at all. We have "a special obligation" to assure ourselves that the District Court properly exercised jurisdiction over the petition, whether or not that issue has been raised by the parties on appeal. Wright v. Musanti , 887 F.3d 577, 583 (2d Cir. 2018). If we determine that District Court "was without jurisdiction," our appellate jurisdiction is limited to the "purpose of correcting the [District Court's] error" in reaching the merits of the petition. Id. (internal quotation marks omitted). We conclude that Dhinsa has Article III standing based on the $100 special assessment that attaches to each of his challenged convictions, and therefore that the District Court properly exercised jurisdiction over the petition.
A. Legal standard: Habeas petitions and standing
Article III of the Constitution limits the federal courts' power to the resolution of "Cases" and "Controversies." U.S. Const. art. III, § 2. A litigant who invokes federal jurisdiction therefore must demonstrate "[s]tanding to sue," a requirement "rooted in the traditional understanding" of what it means to assert a "case or controversy" under Article III. Spokeo, Inc. v. Robins , --- U.S. ----, 136 S.Ct. 1540, 1547, 194 L.Ed.2d 635 (2016). The " 'irreducible constitutional minimum' of standing consists of three elements": the individual initiating the suit "must have (1) suffered an injury in fact, (2) that is fairly traceable to the challenged conduct of the defendant, and (3) that is likely to be redressed by a favorable judicial decision." Id. (quoting Lujan v. Defs. of Wildlife , 504 U.S. 555, 560-61, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992) ). "[S]tanding doctrine evaluates a litigant's personal stake as of the outset of litigation." Klein, on behalf of Qlik Techs., Inc. v. Qlik Techs., Inc ., 906 F.3d 215, 221 (2d Cir. 2018) (quoting Altman v. Bedford Cent. Sch. Dist ., 245 F.3d 49, 70 (2d Cir. 2001) ).
B. Analysis
The District Court concluded that Dhinsa's petition should be dismissed under the concurrent sentence doctrine based on the court's determination that "the success of [Dhinsa's] current petition will not alter the length or nature of his custody," and further, that Dhinsa had failed to demonstrate any redressable collateral consequences arising specifically from the two convictions challenged in his petition. Habeas Order , 238 F.Supp.3d at 431-32. The District Court thus implicitly concluded that Dhinsa lacked standing to bring his petition.5
*78We need not revisit the District Court's analysis of collateral consequences because we conclude that Dhinsa has established Article III standing based on a redressable injury-in-fact: the $100 special assessment that attaches to each of his two challenged convictions.6 We offer here a more extended discussion of special assessments and Article III standing, and in particular, of how our standing analysis in the habeas context differs from the question whether a habeas petitioner is "in custody" when he files his petition.
We note, as a preliminary matter, that "monetary loss" is a quintessential injury in fact, and "even a small financial loss suffices" to establish standing. Carter v. HealthPort Techs., LLC , 822 F.3d 47, 55 (2d Cir. 2016) (alteration and internal quotation marks omitted). An "identifiable trifle is enough," the Supreme Court has explained, because standing doctrine's purpose is "to distinguish a person with a direct stake in the outcome of a litigation-even though small-from a person with a mere interest in the problem." United States v. Students Challenging Regulatory Agency Procedures (SCRAP) , 412 U.S. 669, 689 n.14, 93 S.Ct. 2405, 37 L.Ed.2d 254 (1973) (internal quotations marks omitted). We thus conclude that each of Dhinsa's special assessments "constitutes a concrete injury" that was "caused by the [challenged] conviction." Spencer v. Kemna , 523 U.S. 1, 7, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). The sole remaining question for purposes of standing, then, is whether a special assessment is "redressable by invalidation of the [underlying] conviction." Id. We conclude that it is.
Dhinsa contends in his habeas petition that two of his convictions are unlawful. If his petition is granted, he may be entitled to vacatur of the judgments of conviction, the corresponding sentences, or both. See 28 U.S.C. § 2243 (authorizing courts to "dispose of" a § 2241 habeas petition "as law and justice require");7 United States v.Triestman , 178 F.3d 624, 629 (2d Cir. 1999) ("Courts hearing § 2241 motions have traditionally had the power to vacate or reduce ... sentences" that were entered in violation of "the Constitution or federal law."); see also, e.g. , Willette v. Fischer , 508 F.3d 117, 123 (2d Cir. 2007) (affirming, as habeas relief, vacatur of sentences entered pursuant to convictions that violated the Double Jeopardy Clause). The *79special assessments are part of Dhinsa's sentence, as listed in the criminal judgment that was entered in the District Court. Thus, if Dhinsa succeeds in securing habeas relief as to one or both challenged convictions, he may be entitled to seek return of the related special assessments. See Prost v. Anderson , 636 F.3d 578, 582 n.3 (10th Cir.2011).
This is not to say, however, that Dhinsa could file a habeas petition that directly challenges the imposition of the special assessments. He could not, for example, seek habeas review based on a claim that the District Court incorrectly calculated the amount of a given special assessment. It is well-established that courts may not entertain a petition "addressed solely to noncustodial punishments." Kaminski v. United States , 339 F.3d 84, 87 (2d Cir. 2003). Sections 2241, 2254, and 2255 authorize courts to adjudicate a petition filed by an individual who is "in custody" and who challenges the basis for that custody.8 We have characterized this statutory "custody" requirement as "jurisdictional," and therefore mandatory and non-waivable. United States v. Rutigliano , 887 F.3d 98, 104 (2d Cir. 2018) (internal quotation marks omitted). "[T]he monetary components of criminal sentences, such as fines and restitution orders, generally do not restrict liberty so severely as to satisfy the custody requirement," and so generally do not fall within the purview of a permissible collateral challenge.9 Id. at 104-05. (citing Kaminski , 339 F.3d at 86-87 ). Nor may a party "avoid this conclusion by challenging both the custodial and noncustodial parts of his sentence in the same [habeas petition]." Id. at 105.
Here, however, Dhinsa does not challenge the special assessments themselves. Rather, he challenges the two underlying convictions for informant murder, pursuant to which the District Court imposed both special assessments and life terms of incarceration. We have no trouble concluding that, when Dhinsa filed his § 2241 petition, he was "in custody in relation to the claims" asserted therein. Kaminski , 339 F.3d at 91 ; see also Spencer , 523 U.S. at 7, 118 S.Ct. 978 (noting that the "custody" requirement must be satisfied only at the time the petition is filed). That Dhinsa's custody was independently justified under concurrent, coterminous sentences does not preclude him from satisfying the "custody" requirement. See Maleng v. Cook , 490 U.S. 488, 490-91, 109 S.Ct. 1923, 104 L.Ed.2d 540 (1989) (per curiam) (specifying that a "habeas petitioner [must] be 'in custody' under the conviction or sentence under attack at the time his petition is filed"); see also, e.g. , Tavarez , 814 F.3d 644 (reaching the merits of a habeas petition challenging only one of two concurrent sentences, with no discussion of the jurisdictional "custody" requirement); cf. Garlotte v. Fordice , 515 U.S. 39, 41, 115 S.Ct. 1948, 132 L.Ed.2d 36 (1995) (explaining that a habeas petitioner "remains 'in custody' under all of his sentences until all are served," and so permitting a § 2254 habeas petitioner to challenge an expired sentence *80because he remained incarcerated under additional consecutive sentences).
Although Dhinsa may not assert a direct collateral attack on his special assessments, the assessments are nonetheless redressable injuries for the purposes of Article III standing. "Where a habeas challenge to incarceration results in the overturning of a conviction or of a whole sentence so that the defendant must later be resentenced in toto, the defendant on resentencing may ... question the basis of any [monetary penalty] that might then be assessed." Kaminski , 339 F.3d at 89 n.3. Indeed, this principle extends beyond monetary penalties; if Dhinsa successfully vacates one or more of his convictions, he may be entitled to resentencing on his remaining convictions if he can show that the District Court's sentencing determinations depended in some way on the now-vacated conviction. See Triestman , 178 F.3d at 630 (holding that "the district court had ... the power to resentence [the § 2241 petitioner] to the overall term that he would have received on his interdependent sentencing package absent his unlawful § 924(c) conviction").
For these reasons, we conclude that the special assessment attached to each conviction constitutes a concrete, redressable injury sufficient to establish Article III standing. See Prost , 636 F.3d at 582 n.3. We therefore conclude that Dhinsa has standing to bring the petition notwithstanding his unchallenged concurrent sentences.
II. Jurisdiction under § 2241 and the § 2255(e) savings clause
Dhinsa seeks to collaterally attack his conviction on two counts of informant murder. His prior motion under § 2255, the typical path for a collateral attack by a federal prisoner, leaves him unable to assert these claims in a second such motion absent our permission, which we earlier denied. Dhinsa argues, however, that his claims fall within the "savings clause" in § 2255(e) and that he may therefore bring a habeas petition under § 2241. A petitioner who seeks to establish habeas jurisdiction under this savings clause must make a threshold showing, based on the existing record, that he is innocent of his crime of conviction under a legal theory that was not previously available to him. Here, Dhinsa argues that the conduct for which he was convicted is insufficient to establish guilt under the intervening standard for informant murder articulated in Fowler v. United States , 563 U.S. 668, 131 S.Ct. 2045, 179 L.Ed.2d 1099 (2011).
We disagree. Rather, we find persuasive the District Court's analysis concluding that Dhinsa has failed to meet the requirements of the savings clause.10 Because the District Court entered a judgment denying the petition on the merits, however, we vacate that portion of the judgment and remand for entry of a judgment dismissing the petition for lack of jurisdiction.
A. Legal standard
In general, federal prisoners who seek to collaterally attack the basis for imposing a sentence-including by *81challenging the underlying conviction-must move "to vacate, set aside or correct the sentence" under 28 U.S.C. § 2255(a). See 28 U.S.C. §§ 2255(e), 2244(a) ; Adams , 372 F.3d at 134. To challenge "the execution of a sentence," including challenges to disciplinary actions, prison conditions, or parole decisions, by contrast, an application under 28 U.S.C. § 2241 provides the "proper means." Adams , 372 F.3d at 135. In his present petition, Dhinsa challenges the sufficiency of the evidence as to two of his convictions. Section 2255 thus at first glance appears to be the appropriate vehicle for Dhinsa's claims. The remedies under § 2255 are unavailable to him, however: he filed an initial § 2255 motion in 2002, and this Court has already determined that the instant application does not satisfy the requirements of § 2255(h) for allowing a "second or successive" motion. Faced with that obstacle, Dhinsa invokes the savings clause in § 2255(e), which, in some circumstances, confers federal habeas jurisdiction where it would not otherwise exist: a federal prisoner may pursue a petition under § 2241 if it "appears that the remedy [under § 2255 ] is inadequate or ineffective to test the legality of his detention." 28 U.S.C. § 2255(e).
A petitioner cannot claim that § 2255 is "inadequate or ineffective" merely because his prior § 2255 motion was denied, however. Id. We have interpreted the savings clause of subsection (e) to authorize a § 2241 petition only when § 2255 is unavailable and the petition is filed by an individual who (1) "can prove 'actual innocence on the existing record,' " and (2) " 'could not have effectively raised [his] claim[ ] of innocence at an earlier time,' " perhaps due to an intervening change in the governing interpretation of the statute of conviction. Cephas v. Nash , 328 F.3d 98, 104 (2d Cir. 2003) (quoting Triestman v. United States , 124 F.3d 361, 363 (2d Cir. 1997) ). To make a threshold showing of "actual innocence" under the first prong, a petitioner "must demonstrate that, in light of all the evidence, it is more likely than not that no reasonable juror would have convicted him." Bousley v. United States , 523 U.S. 614, 623, 118 S.Ct. 1604, 140 L.Ed.2d 828 (1998) (internal quotation marks omitted). The petitioner must "state a colorable ... claim," in other words, that the trial evidence was insufficient to support his conviction on a correct understanding of the law. Cephas , 328 F.3d at 108. The court must thus determine whether, "after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt." Coleman v. Johnson , 566 U.S. 650, 654, 132 S.Ct. 2060, 182 L.Ed.2d 978 (2012) (per curiam) (emphasis in original) (internal quotation marks omitted).
Because the savings clause articulates a jurisdictional requirement, a court adjudicating a § 2241 petition must confirm that the savings clause can be applied at all before proceeding with a full merits review of the petitioner's claims. See 28 U.S.C. § 2255(e) (providing that a § 2241 petition seeking the type of relief available under § 2255"shall not be entertained ... unless [the savings clause applies]" (emphasis added) ); Adams , 372 F.3d at 136 ("[I]f a prisoner moving under § 2241 cannot make the necessary showing that a § 2255 motion is 'inadequate or ineffective,' the district court 'must either dismiss the habeas petition for lack of jurisdiction or recast it as a § 2255 motion.' " (quoting Cephas , 328 F.3d at 104 ) ). In many cases-this one included-such analysis will overlap with analysis on the merits.11
*82The threshold savings clause analysis does not replace a full merits analysis, however; they are not co-extensive. For example, the district court may in the merits proceeding provide the government an opportunity to "rebut" the factual basis for the petitioner's claim by "present[ing] any admissible evidence of petitioner's guilt[,] even if that evidence was not presented" during the underlying criminal proceedings." Bousley , 523 U.S. at 623-24, 118 S.Ct. 1604 (1998) (cautioning that " 'actual innocence' means factual innocence, not mere legal insufficiency"). Thus, a petitioner who makes the threshold showing of legal innocence on the existing record will not necessarily be entitled to habeas relief. We therefore proceed here with our scrutiny of Dhinsa's "actual innocence" claims.
B. Analysis
Section 1512(a)(1)(C) criminalizes the act of killing a person with the intent to, inter alia , prevent someone from "communicat[ing] ... information relating to the commission or possible commission of a Federal offense" to a federal "law enforcement officer." 18 U.S.C. § 1512(a)(1)(C). A jury convicted Dhinsa on two counts of informant murder based on evidence that he ordered the murders of Manmohan Singh and Satinderjit Singh. Shortly after the trial-but before judgment was entered-this Court declared in United States v. Diaz , 176 F.3d 52 (2d Cir. 1999), that § 1512(a)(1)(C) requires the "government [to] prove that at least one of the law-enforcement-officer communications which the defendant sought to prevent would have been with a federal officer." Diaz , 176 F.3d at 91 (internal quotation marks omitted). In his direct appeal, Dhinsa did not challenge the evidentiary basis for his § 1512(a)(1)(C) convictions as insufficient under Diaz 's standard. In 2011, a decade after this Court affirmed Dhinsa's convictions, the Supreme Court specified in Fowler that a defendant is guilty of informant murder only if the victim was "reasonably likely" to have communicated with a federal law enforcement officer. 563 U.S. at 678, 131 S.Ct. 2045. We need not decide whether Fowler materially altered this Circuit's standard for informant murder, as Dhinsa claims, because we conclude that Dhinsa has failed to satisfy the first prong of the savings clause analysis: demonstrating his innocence on the existing record. Triestman , 124 F.3d at 363. In our view, a juror could reasonably conclude that both Manmohan and Satinderjit were "reasonably likely" to have communicated with federal officials, as Fowler requires.
The trial evidence showed that Manmohan and Satinderjit were both "murdered on Dhinsa's orders" after they started making inquiries into the Singh Enterprise's criminal activities. Dhinsa I , 243 F.3d at 643. Manmohan was inquiring about the disappearance of his brother Kulwant, who had worked at one of Dhinsa's Citygas stations. Id. Testimony showed that Dhinsa believed that Manmohan also saw Dhinsa and an accomplice "shoot somebody," id. at 657, making him a potential witness against Dhinsa regarding a second crime. After Manmohan was killed in March 1997, Satinderjit began cooperating with the New York State Police investigation of the Singh Enterprise's role in, inter alia , Kulwant's disappearance, Manmohan's murder, and Citygas's fraudulent pump-rigging technology. See id. at 644. As part of that cooperation, Satinderjit participated in a May 1997 raid *83of the Citygas offices in Brooklyn during which state police seized firearms and arrested four individuals, including Dhinsa himself. Id. The following month, in June 1997, Satinderjit was murdered.
We are aware of no record evidence suggesting that either Manmohan or Satinderjit communicated directly with any federal law enforcement officials before he died. Dhinsa acknowledges, however, that federal authorities began "investigat[ing] the Singh Enterprise in relation to the seized firearms" in July 1997, only one month after Satinderjit's death and four months after Manmohan's. Appellant's Br. 5. Shortly thereafter, federal prosecutors indicted Dhinsa on twenty-nine counts, several of which related to the conduct that Manmohan and Satinderjit had been investigating before they were killed: Kulwant's kidnapping, Manmohan's murder, and the pump-rigging technology.12
In Dhinsa's view, this record fails to establish that either Manmohan or Satinderjit was "reasonably likely" to communicate with a federal law enforcement officer, notwithstanding any communications they made, or might have made, to state police officers. We disagree.
We conclude, first, that Dhinsa's crimes would likely have been investigated and prosecuted by federal officials even if Dhinsa had not murdered Manmohan and Satinderjit. We are conscious that our "federal nexus inquiry" under § 1512(a)(1)(C) should not place "undue weight [on] the mere fact" that the defendant was, in fact, "convicted of [ ] federal crime[s]" beyond the informant murders themselves. United States v. Veliz , 800 F.3d 63, 75 (2d Cir. 2015). "[T]he frequent overlap between state and federal crimes" means that many unremarkable criminal acts will constitute violations of federal law, even though, "as a practical matter," the "crimes, investigations, and witness tampering ... are purely state in nature." Fowler , 563 U.S. at 677, 131 S.Ct. 2045. Dhinsa's crimes, though, were hardly unremarkable. As described above, Dhinsa headed a multi-year, multimillion-dollar racketeering enterprise through which he defrauded consumers, bribed public officials, and committed heinous acts of violence and murder. Moreover, the government suspected Dhinsa of fraud and kidnapping that involved activity outside New York State.13 See Dhinsa I , 243 F.3d at 645-46 ; App'x 96-97. A juror could reasonably conclude that a racketeering enterprise of this interstate scope and on such a large scale was likely to be investigated and prosecuted by federal officials. See, e.g. , Veliz , 800 F.3d at 75 (finding federal involvement reasonably likely where defendant "committed multiple related crimes across multiple states, with multiple accomplices that a jury *84found to constitute an association-in-fact RICO enterprise").
This conclusion does not end our inquiry, however. As Dhinsa points out, "[i]t is not enough that federal authorities simply become involved in an investigation. Rather, ... the government must prove it reasonably likely that a relevant communication would have been made to a federal officer." Appellant's Reply Br. 5 (emphases in original); see 18 U.S.C. § 1512(a)(1)(C) (criminalizing a killing intended to "prevent [a] communication ... to a [federal] law enforcement officer or judge" (emphasis added) ). In arguing that the government failed to meet this standard, Dhinsa emphasizes that state police took the lead in investigating the Singh Enterprise, while federal officers-at least initially-played a more limited role by, for example, providing technical assistance related to tracking firearms.
We are unpersuaded. Dhinsa fails to recognize that § 1512 's reference to "law enforcement officer[s]" encompasses not only the officials who investigate the case, but also those who prosecute it. See Fowler , 563 U.S. at 675-76, 131 S.Ct. 2045 ( Section 1512"appl[ies] where it is plain that federal officers would have been involved in investigating and prosecuting the offense." (emphasis added) ); United States v. Snyder , 865 F.3d 490, 497 (7th Cir. 2017) ("[I]f the underlying crime ... would have been prosecuted in federal court, then it is reasonably likely that the witness would have spoken with a federal officer during the course of that prosecution."). The government may satisfy its burden, then, by showing that a victim was reasonably likely to have served as a witness in a federal criminal trial or otherwise to have communicated with a federal officer as the prosecution prepared its case.
A juror could reasonably find that the government met that burden here, and, therefore, Dhinsa cannot demonstrate actual innocence on the existing record. As we first observed some years ago, "[t]he [trial] record amply demonstrates that Dhinsa murdered Manmohan and Satinderjit to deprive the government of potential witnesses." Dhinsa I , 243 F.3d at 657 (internal quotation marks and alterations omitted). We have already concluded that a federal prosecution was reasonably likely, and, as noted above, Dhinsa's superseding indictment included several charges related to the very criminal conduct that Manmohan and Satinderjit had been investigating. Both victims had been looking into Kulwant's disappearance. Dhinsa believed that Manmohan had personally witnessed Dhinsa shoot someone. Satinderjit was cooperating with a state investigation of the Singh Enterprise and had participated in a raid that resulted in Dhinsa's arrest. Given those facts, a juror could reasonably find that Manmohan and Satinderjit's likelihood of speaking with a federal official was far from "remote, outlandish, or simply hypothetical." Fowler , 563 U.S. at 678, 131 S.Ct. 2045.
Dhinsa has failed to state a colorable claim that "no reasonable juror would have convicted him" on either count of informant murder. Bousley , 523 U.S. at 623, 118 S.Ct. 1604. Thus, the District Court correctly concluded that Dhinsa has fallen short of satisfying the threshold analysis required under the § 2255(e) savings clause and that he is therefore not entitled to bring a § 2241 habeas petition. Although the savings clause imposes a jurisdictional threshold, the District Court entered a judgment denying the petition on the merits. Accordingly, we remand that portion of the judgment so that the District Court may enter an amended judgment *85that dismisses the petition for lack of jurisdiction.
CONCLUSION
Dhinsa's § 2241 habeas petition challenges only two of six concurrent life sentences. Thus, a successful petition would not affect the length of his confinement. He has standing to bring his petition, however, because the special assessment that attaches to each of the challenged convictions presents a concrete, redressable injury sufficient to establish Article III standing. We are nonetheless precluded from reaching the merits of Dhinsa's habeas claims because he has failed to show that his petition satisfies the jurisdictional requirements of the savings clause contained in § 2255(e). We conclude that, on the existing record, a juror could reasonably find that Dhinsa is guilty of both charged counts of informant murder pursuant to 18 U.S.C. § 1512(a)(1)(C). Dhinsa therefore is not entitled to bring a habeas petition under § 2241.
Because the District Court entered a judgment denying the petition on the merits, we VACATE that portion of the judgment that denied the petition and REMAND the cause with instructions for the District Court to enter a judgment dismissing the petition for lack of jurisdiction.
The District Court and the parties refer to this crime as "obstruction of justice murder." We find this term inadequately precise. The "Obstruction of Justice" chapter of the United States Code, chapter 73 of title 18, contains multiple provisions that prohibit the killing, threatened killing, or attempted killing of particular types of victims for particular illicit purposes. See, e.g. , 18 U.S.C. §§ 1503(a) (prohibiting "threats or force" intended to influence, intimidate, or impede, or to retaliate against jurors or officers of the court); 1512(a) (prohibiting a killing or attempted killing intended to prevent any person from testifying, producing evidence, or communicating with law enforcement or judicial officers); 1513(a) (prohibiting a killing or attempted killing intended as retaliation against a witness or informant). For these reasons, we refer to the instant crime of conviction as "informant murder."
Because Dhinsa's direct appeal challenged a jury's guilty verdicts, this Court considered the trial evidence "in the light most favorable to the government, crediting any inferences that the jury might have drawn in its favor." Dhinsa I , 243 F.3d at 643 (internal quotation marks omitted). That approach is equally appropriate for our review of Dhinsa's habeas claims in the instant appeal, as explained below in Discussion Section II.A.
Dhinsa filed the 2012 § 2241 petition in the Middle District of Pennsylvania, his then-current district of incarceration. Shortly thereafter, he asserted substantially identical arguments in a § 2255 motion filed in the District Court in Eastern District of New York. The District Court transferred that motion to this Court on May 31, 2012, for possible certification as a second or successive § 2255 motion. While that matter was pending, the parties agreed to transfer Dhinsa's § 2241 petition from the Middle District of Pennsylvania to the Eastern District of New York, at which time Dhinsa voluntarily dismissed the pending § 2255 motion.
In Ray v. United States , 481 U.S. 736, 107 S.Ct. 2093, 95 L.Ed.2d 693 (1987) (per curiam), the Supreme Court vacated an appellate court's invocation of the concurrent sentence doctrine in a direct appeal. The concurrent sentence doctrine was unavailable, the Court explained, because "the District Court imposed a $50 assessment on each count" of conviction, and so the defendant's "sentences are not concurrent" in all respects. Id. at 737, 107 S.Ct. 2093. Because all federal convictions carry a mandatory special assessment, see 18 U.S.C. § 3013(a), Ray is understood to have "abolished the [concurrent sentence] doctrine for direct review of federal convictions." 7 Wayne R. LaFave et al., Crim. Proc. § 27.5(b) (4th ed.). We decline to decide whether Ray similarly precludes application of the concurrent sentence doctrine in the habeas context.
The District Court applied the legal framework developed in Nowakowski v. New York , 835 F.3d 210 (2d Cir. 2016), and, in so doing, implicitly concluded that Dhinsa's petition is not justiciable. In Nowakowski , we articulated a burden-shifting framework for determining whether a habeas petition is rendered moot by a petitioner's release from custody. We explained that the petitioner bears the burden, in the first instance, of "identify[ing] some continuing collateral consequences that may flow from his criminal conviction." Id. at 225. Once the petitioner has identified specific collateral consequences, the government may attempt to "prove ... that there is 'no possibility' such consequences will attach to [the petitioner's] conviction." Id. (quoting Sibron v. New York , 392 U.S. 40, 57, 88 S.Ct. 1889, 20 L.Ed.2d 917 (1968) ). The District Court concluded here that the government "easily met" its burden of showing that Dhinsa's informant murder convictions would not produce any future collateral consequence distinct from those arising from his other, unchallenged convictions. Habeas Order , 238 F.Supp.3d at 432. We need not apply the Nowakowski framework in this case, however, because Dhinsa remains in custody and no "intervening circumstance" has deprived him " 'of a personal stake in the outcome of the lawsuit, at any point during litigation' after its initiation" so as to render his petition moot. Klein, on behalf of Qlik Techs., Inc. , 906 F.3d 215, 221 (2d Cir. 2018) (quoting Genesis Healthcare Corp. v. Symczyk , 569 U.S. 66, 72, 133 S.Ct. 1523, 185 L.Ed.2d 636 (2013) ).
Nowakowski , by way of contrast, involved a petitioner who was unable to assert standing based on financial collateral consequences. Robert Nowakowski's state conviction carried a $100 fine, but before Nowakowki filed his habeas petition under 28 U.S.C. § 2254, the state criminal court vacated the fine based on Nowakowski's inability to pay. See Nowakowski , 835 F.3d at 214.
This "broad" provision has been interpreted to authorize relief beyond immediate "discharge of the applicant from physical custody." Carafas v. LaVallee , 391 U.S. 234, 239, 88 S.Ct. 1556, 20 L.Ed.2d 554 (1968). For additional guidance, we may consult the text of § 2255, which directs that a court, upon granting a habeas petition, "shall vacate and set the judgment aside," and shall also "discharge the prisoner or resentence him ... or correct the sentence as may appear appropriate." 28 U.S.C. § 2255(b) ; see also Hill v. UnitedStates , 368 U.S. 424, 427, 82 S.Ct. 468, 7 L.Ed.2d 417 (1962) (Section 2255"was intended [ ] to provide in the sentencing court a remedy exactly commensurate with that which had previously been available by habeas corpus [under § 2241 ] in the court of the district where the prisoner was confined ." (emphasis added) ).
See, e.g. , 28 U.S.C. § 2241(c)(3) ("The writ of habeas corpus shall not extend to a prisoner unless ... [h]e is in custody in violation of the Constitution or laws or treaties of the United States.").
Although this Court has "left open the possibility of a [monetary penalty] imposing such a severe restraint on individual liberty as to equate to custody, [we have] also observed that such situations will likely be rare." Rutigliano , 887 F.3d at 106 (internal quotation marks omitted). Here, Dhinsa expressly waived any argument "that the burden of a special assessment itself amounts to custody." Appellant's Br. 19 (internal quotation marks and alterations omitted) (emphasis in original).
The District Court also suggested that Dhinsa's unchallenged concurrent life sentences make him per se ineligible to assert a § 2241 petition under the savings clause in § 2255(e). See Habeas Order , 238 F.Supp.3d at 427 (discussing Triestman v. United States , 124 F.3d 361, 379 (2d Cir. 1997) ). We need not review the District Court's reasoning on this point because we affirm the District Court's conclusion regarding the savings clause on other grounds. See Lotes Co. v. Hon Hai Precision Indus. Co. , 753 F.3d 395, 413 (2d Cir. 2014) ("[T]his Court may affirm on any basis for which there is sufficient support in the record." (internal quotation marks omitted) ).
The District Court reached the same substantive conclusion that we do but denied the petition on the merits. Because the jurisdictional inquiry must precede merits analysis, however, we find that dismissing the petition on jurisdictional grounds is the correct result.
The jury acquitted Dhinsa on the kidnapping charges related to Kulwant, but convicted him on charges related to Manmohan's murder and the pump-rigging technology scheme.
The jury convicted Dhinsa on two counts related to interstate kidnapping, but this Court vacated those convictions on procedural grounds. Dhinsa I , 243 F.3d at 669, 677-78. For our purposes in this appeal, it is immaterial whether Dhinsa was found guilty on the kidnapping charges. We are concerned with the likelihood that federal law enforcement officials would see fit to investigate Dhinsa's activities or prosecute Dhinsa's case in federal court. That likelihood increases when federal prosecutors believe they have sufficient evidence to charge a defendant with interstate criminal activity. See Veliz , 800 F.3d at 75 (noting the "interstate nature of the offenses" as a relevant factor when determining the likelihood of "federal involvement" in a criminal investigation).
