BITTNER v . UNITED STATES
**certiorari to the united states court of appeals for**  **the **  **fth circuit** No. 21–1195. Argued November 2, 2022—Decided February 28, 2023 The Bank Secrecy Act (BSA) and its implementing regulations require

U. S. persons with certain fnancial interests in foreign accounts to fle an annual report known as an “FBAR”—the Report of Foreign Bank and Financial Accounts. The statute imposes a maximum $10,000 pen

alty for nonwillful violations of the law. These reports are designed to help the government trace funds that may be used for illicit purposes and identify unreported income that may be subject to taxation. Peti

tioner Alexandru Bittner—a dual citizen of Romania and the United States—learned of his BSA reporting obligations after he returned to the United States from Romania in 2011, and he subsequently submitted the required annual reports covering fve years (2007 through 2011). The government deemed Bittner's late-fled reports defcient because the reports did not address all accounts as to which Bittner had either signatory authority or a qualifying interest. Bittner fled corrected FBARs providing information for each of his accounts—61 accounts in 2007, 51 in 2008, 53 in 2009 and 2010, and 54 in 2011. The government neither contested the accuracy of Bittner's new flings nor suggested that Bittner's previous errors were willful. But because the govern

ment took the view that nonwillful penalties apply to each account not accurately or timely reported, and because Bittner's fve late-fled an

nual reports collectively involved 272 accounts, the government calcu

lated the penalty due at $2.72 million. Bittner challenged that penaltyin court, arguing that the BSA authorizes a maximum penalty for nonwillful violations of $10,000 per report, not $10,000 per account. The Fifth Circuit upheld the government's assessment. Held : The BSA's $10,000 maximum penalty for the nonwillful failure to fle

a compliant report accrues on a per-report, not a per-account, basis. Pp. 92–101, 103–104.

(a) The Court begins with the terms of the most immediately relevant statutory provisions—31 U. S. C. § 5314, which delineates an individual's legal duties under the BSA, and § 5321, which outlines the penalties that follow for failing to discharge those duties. Section 5314 provides that the Secretary of the Treasury “shall” require certain persons to “keep records, fle reports, or keep records and fle reports” when they “mak[e] a transaction or maintai[n] a relation” with a “foreign fnancial agency.”86 BITTNER v. UNITED STATES Syllabus The statute states that reports “shall contain” information about “the identity and address of participants in a transaction or relationship,” “the legal capacity in which a participant is acting,” and “the identity of real parties in interest,” along with a “description of the transaction.” Section 5314 does not speak of accounts or their number but rather the legal duty to fle reports which must include various kinds of informa

tion about an individual's foreign “transaction[s] or relationship[s].” Vi

olation of § 5314's reporting obligation is binary: One fles a report “in the way and to the extent the Secretary prescribes,” or one does not; multiple willful errors may establish a violation of § 5314 but even a single mistake, willful or not, constitutes a § 5314 violation. The only distinction the law draws between a report containing a single mis

take and one containing multiple mistakes concerns the appropriate penalty.

Section 5321 authorizes the Secretary to impose a civil penalty of up to $10,000 for “any violation” of § 5314. The “nonwillful” penalty provi

sion in §§ 5321(a)(5)(A) and (B)(i) does not speak in terms of accounts but rather pegs the quantity of nonwillful penalties to the quantity of “violation[s].” Section 5314 provides that a violation occurs when an individual fails to fle a report consistent with the statute's commands. Multiple defcient reports may yield multiple $10,000 penalties, and even a seemingly simple defciency in a single report may expose an individ

ual to a $10,000 penalty. But penalties for nonwillful violations accrue on a per-report, not a per-account, basis.

To be sure, for certain cases that involve willful violations, the statute does tailor penalties to accounts. Section 5321 specifcally addresses a subclass of willful violations that involve “a failure to report the exist

ence of an account or any identifying information required to be pro

vided with respect to an account.” § 5321(a)(5)(D)(ii). In such cases, the Secretary may impose a maximum penalty of either $100,000 or 50% of “the balance in the account at the time of the violation”—whichever is greater. §§ 5321(a)(5)(C) and (D)(ii). The government maintains that because Congress explicitly authorized per-account penalties for some willful violations, the Court should infer that Congress meant to do so for analogous nonwillful violations. But the government's interpreta

tion defes a traditional rule of statutory construction: When Congress includes particular language in one section of a statute and omits it from a neighbor, the Court normally understands that difference in language to convey a difference in meaning ( expressio unius est exclusio alter

ius ). Here the statute twice provides evidence that when Congress wished to tie sanctions to account-level information, it knew exactly how to do so. Congress said in §§ 5321(a)(5)(C) and (D)(ii) that penalties for certain willful violations may be measured on a per-account basis. And Congress said in § 5321(a)(5)(B)(ii) that a person may invoke the reason

-87 Cite as: 598 U. S. 85 (2023) Syllabus able cause exception only on a showing of per-account accuracy. But Congress did not say that the government may impose nonwillful penal

ties on a per-account basis. Pp. 92–96.

(b) The Court fnds a number of additional contextual clues that cut against the government's theory in this case. First, the government has repeatedly issued guidance to the public—in various warnings, fact sheets, and instructions—that seems to tell the public that the failure to fle a report represents a single violation exposing a nonwillful viola

tor to one $10,000 penalty. While the government's guidance docu

ments do not control the Court's analysis, courts may consider the incon

sistency between the government's current view and its past views when weighing the persuasiveness of any interpretation it offers. Skidmore v. Swift & Co. , 323 U. S. 134, 140.

Second, the drafting history of the nonwillful penalty provision under

mines the theory the government urges the Court to adopt. In 1970, the BSA included penalties only for willful violations. In 1986, Con

gress authorized the imposition of penalties on a per-account basis for certain willful violations. When Congress amended the law again in 2004 to authorize penalties for nonwillful violations, Congress could have, but did not, simply use language from its 1986 amendment to ex

tend per-account penalties for nonwillful violations.

Still other features of the BSA and its regulatory scheme suggest the law aims to provide the government with a report suffcient to tip it to the need for further investigation, not to ensure the presentation of every detail or maximize revenue for each mistake. Consider that Con

gress declared that the BSA's “purpose” is “to require” certain “reports” or “records” that may assist the government in various kinds of investi

gations. § 5311. Absent is any indication that Congress sought to maximize penalties for every nonwillful mistake. Similarly, the Secre

tary's regulations implementing the BSA require individuals with fewer than 25 accounts to provide details about each account while individuals (like Bittner) with 25 or more accounts do not need to list each account or provide account-specifc details unless the Secretary requests more “detailed information.” 31 CFR § 1010.350(g)(1). Finally, the govern

ment's per-account penalty reading invites anomalies—for example, sub

jecting willful violators to lower penalties than nonwillful violators— avoided by reading the nonwillful penalty to apply on a per-report basis.

The government replies that the per-report interpretation risks the anomaly that the Secretary could formulate reporting requirements to require a separate report for each account and in that way effectively achieve a per-account penalty for nonwillful violations. What this proves is unclear, as the Secretary's discretion to require more (or fewer) reports is not at issue here, and in any event does not answer88 BITTNER v. UNITED STATES Opinion of the Court whether the Secretary may impose nonwillful penalties on a per-report or per-account basis. Pp. 96–101.

(c) Best read, the BSA treats the failure to fle a legally compliant report as one violation carrying a maximum penalty of $10,000. Pp. 103–104. 19 F. 4th 734, reversed and remanded.

S. 85 (2023) Opinion of the Court federal government about their foreign bank accounts. The st atute imposes a maximum $10,000 penalty for nonwillful violations of the law. But recently a question has arisen. Does someone who fails to fle a timely or accurate annual report commit a single violation subject to a single $10,000 penalty? Or does that person commit separate violations and incur separate $10,000 penalties for each account not properly recorded within a single report? The answer makes a difference, especially for immigrants who hold accounts abroad and Americans who make their lives outside the country. On one view, penalties accrue on a per-report basis. So, for example, a single late-fled report disclosing the existence of 10 accounts may yield a maximum fne of $10,000. On another view, penalties multiply on a per-account basis, so the same report can invite a fne of $100,000 even if the individual's foreign holdings or total net worth do not approach that amount. Because the Ninth Cir

cuit read the law one way and the Fifth Circuit the other, we agreed to take this case. I The Bank Secrecy Act (BSA) does not make it illegal to hold foreign accounts. Nor does the BSA tax those ac

counts. To the contrary, the federal government has ac

knowledged that “U. S. persons maintain overseas fnancial accounts for a variety of legitimate reasons including con

venience and access.” IRS Pub. 5569, Report of Foreign Bank & Financial Accounts (FBAR) Reference Guide, p. 1 (Rev. 3–2022). As relevant here, the BSA simply requires those who possess foreign accounts with an aggregate bal

ance of more than $10,000 to fle an annual report on a form known as an “FBAR”—the Report of Foreign Bank and Fi

nancial Accounts. 31 U. S. C. § 5314; 31 CFR § 1010.306 (2021). These reports are designed to help the government “trace funds” that may be used for “illicit purposes” and identify “unreported income” that may be subject to taxation90 BITTNER v. UNITED STATES Opinion of the Court separately under the terms of the Internal Revenue Code. FB AR Reference Guide, at 1. The facts of the Ninth and Fifth Circuit cases help illumi

nate the particular question about the BSA now before us. The frst dispute involved Jane Boyd, an American citizen who held 13 relevant accounts in the United Kingdom. The amounts in those accounts increased signifcantly after her father died in 2009 and she deposited her inheritance. United States v. Boyd , 991 F. 3d 1077, 1079 (CA9 2021). Be

cause the aggregate amount in Ms. Boyd's accounts exceeded $10,000 in 2009, she should have fled an FBAR in 2010. Ne

glecting to do so, she corrected the error in 2012, submitting a complete and accurate report at that time. Ibid . The government acknowledged that Ms. Boyd's violation of the law was “non-willful.” Still, the government said, it had the right to impose a $130,000 penalty—$10,000 for each of her 13 late-reported accounts. Ibid

. Ms. Boyd challenged the penalty in court where she ar

gued that her failure to fle a single timely FBAR subjected her to a single maximum penalty of $10,000. The district court rejected that argument and sided with the govern

ment. United States v. Boyd , 123 AFTR 2d 2019–1651 (CD Cal. 2019). But in time the Ninth Circuit vindicated Ms.Boyd's view, holding that the BSA authorizes “only one nonwillful penalty when an untimely, but accurate, FBAR is fled, no matter the number of accounts.” 991 F. 3d, at 1078. More recently, the same question arose in the Fifth Circuit in a case involving Alexandru Bittner. Born and raised in Romania, Mr. Bittner immigrated to the United States at a young age in 1982. He worked frst as a dishwasher and later as a plumber and along the way became a naturalized citizen. After the fall of communism, Mr. Bittner returned to Romania in 1990 where he launched a successful business career. Like many dual citizens, he did not appreciate that U. S. law required him to keep the government apprised of91 Cite as: 598 U. S. 85 (2023) Opinion of the Court his overseas fnancial accounts even while he lived abroad. 19 F. 4th 734, 739–740 (CA5 2021). Shortly after returning to the United States in 2011, Mr. Bittner learned of his re

porting obligations and engaged an accountant to help him prepare the required reports—covering fve years, from 2007 through 2011. Id ., at 739. But the story did not end there. The government identi

fed a problem in the late-fled reports. While those reports provided details about Mr. Bittner's largest account, they ne

glected to address 25 or more other accounts over which he had signatory authority or in which he had a qualifying in

terest. Ibid. After the government informed him of this defciency, Mr. Bittner hired a new accountant who helped him fle corrected FBARs for each year in question. Ibid

. Under governing regulations, flers with signatory authority over or a qualifying interest in fewer than 25 accounts must provide details about each account, but individuals with 25 or more accounts need only check a box and disclose the total number of accounts. 31 CFR § 1010.350(g). Instead of em

ploying that expediency, however, Mr. Bittner and his new accountant volunteered details for each and every one of his accounts—61 accounts in 2007, 51 in 2008, 53 in 2009 and 2010, and 54 in 2011. 19 F. 4th, at 739–740. The question then turned to what penalty Mr. Bittner should pay. The government did not contest the accuracy of Mr. Bittner's new flings. Nor did the government sug

gest that his previous errors were willful. But because the government took the view that nonwillful penalties apply to each account not accurately or timely reported, and because Mr. Bittner's late-fled reports for 2007–2011 collectively in

volved 272 accounts, the government thought a fne of $2.72 million was in order. Id., at 739–740. Like Ms. Boyd before him, Mr. Bittner challenged his pen

alty in court, arguing that the BSA authorizes a maximum penalty for nonwillful violations of $10,000 per report, not92 BITTNER v. UNITED STATES Opinion of the Court $10,000 per account. As he put it, an individual's failure to fle fve reports in a timely manner might invite a penalty of $50,000, but it cannot support a penalty running into the millions. The district court agreed with Mr. Bittner's read

ing of the law, 469 F. Supp. 3d 709, 724–726 (ED Tex. 2020), but the Fifth Circuit upheld the government's assessment, 19 F. 4th, at 749. II With those facts in mind, the question before us boils down to this: Does the BSA's $10,000 penalty for nonwillful violations accrue on a per-report or a per-account basis? Mr. Bittner urges us to agree with the Ninth Circuit and hold that the law authorizes a single $10,000 fne for each untimely or inaccurate report. The government defends the judgment of the Fifth Circuit and asks us to hold that a new $10,000 penalty attaches to each account not timely or accu

rately disclosed within a report. A To resolve who has the better reading of the law, we begin with the terms of the most immediately relevant statutory provisions, 31 U. S. C. § 5314 and § 5321. The frst delineates an individual's legal duties under the BSA, the second out

lines the penalties that follow for failing to discharge those duties. Section 5314 provides that the Secretary of the Treasury “shall” require certain persons to “keep records, fle reports, or keep records and fle reports” when they “mak[e] a trans

action or maintai[n] a relation” with a “foreign fnancial agency.” § 5314(a). When it comes to the duty to fle re

ports, the relevant duty in our case, the statute says that reports “shall contain” information about “the identity and address of participants in a transaction or relationship,” “the legal capacity in which a participant is acting,” and “the iden

-93 Cite as: 598 U. S. 85 (2023) Opinion of the Court tity of real parties in interest,” along with a “description of the transaction.” §§ 5314(a)(1)–(4). The law also directs the Secretary to prescribe “the way and . . . the extent” to which reports must be fled. § 5314(a). Immediately, one thing becomes clear. Section 5314 does not speak of accounts or their number. The word “account” does not even appear. Instead, the relevant legal duty is the duty to fle reports. Of course, those reports must include various kinds of information about an individual's foreign “transaction[s] or relationship[s].” But whether a report is fled late, whether a timely report contains one mistake about the “address of [the] participants in a transaction,” or whether a report includes multiple willful errors in its “de

scription of . . . transaction[s],” the duty to supply a com

pliant report is violated. Put another way, the statutory obligation is binary. Either one fles a report “in the way and to the extent the Secretary prescribes,” or one does not. Multiple willful errors about specifc accounts in a single re

port may confrm a violation of § 5314, but even a single nonwillful mistake is enough to pose a problem. One way or another, § 5314 is violated. The only distinction the law draws between these cases concerns the appropriate penalty. That's where § 5321 comes in. As a baseline, § 5321(a)(5) authorizes the Secretary to impose a civil penalty of up to $10,000 for “any violation” of § 5314. 31 U. S. C. §§ 5321(a) (5)(A) and (B)(i). Some call this the “nonwillful” penalty provision. And here again, one thing is immediately appar

ent: The law still does not speak of accounts or their number. Instead, the statute pegs the quantity of nonwillful penalties to the quantity of “violation[s].” And as we have seen, § 5314 provides that a violation occurs when an individual fails to fle a report consistent with the statute's commands. So multiple defcient reports may yield multiple $10,000 pen

alties, and even a seemingly simple defciency in a single re

-94 BITTNER v. UNITED STATES Opinion of the Court port may expose an individual to a $10,000 penalty. But in a ll cases, penalties for nonwillful violations accrue on a perreport, not a per-account, basis. 1 To be sure, the statute's penalty provisions do not stop there. Section 5321 goes on to say that if an individual “willfully” violates § 5314, he may face a maximum penalty of $100,000. § 5321(a)(5)(C)(i)(I). The statute then adds an even more specifc rule for a subclass of willful violations— those that involve “a failure to report the existence of an account or any identifying information required to be pro

vided with respect to an account.” § 5321(a)(5)(D)(ii). In cases like that, the law authorizes the Secretary to impose a maximum penalty of either $100,000 or 50% of “the balance in the account at the time of the violation”—whichever is greater. §§ 5321(a)(5)(C) and (D)(ii). So here, at last, the law does tailor penalties to accounts. But the statute does so only for a certain category of cases that involve willful violations, not for cases like ours that involve only nonwill

- ful violations. No surprise, the government seeks to turn this feature of the law to its advantage. Because Congress explicitly au

thorized per-account penalties for some willful violations, the government asks us to infer that Congress meant to do so for analogous nonwillful violations as well. Brief for United States 20–23. But, in truth, this line of reasoning cuts against the government. When Congress includes particu

lar language in one section of a statute but omits it from a neighbor, we normally understand that difference in lan

guage to convey a difference in meaning ( expressio unius est exclusio alterius ). The government's interpretation defes this traditional rule of statutory construction. See, e. g. , De

partment of Homeland Security v. MacLean , 574 U. S. 383, 391 (2015); Gallardo v. Marstiller, 596 U. S. –––, –––, ––– (2022).

1 What, if any, mens rea the government must prove to impose a “non

willful” penalty is not before us.95 Cite as: 598 U. S. 85 (2023) Opinion of the Court The government's problem repeats itself too. Section 5321(a)(5)(B)(ii) contains a “[r]easonable cause exception.” That exception allows an individual to escape a penalty (say for fling late) only if his violation was nonwillful, “due to reasonable cause,” and the report he eventually fles accu

rately refects each and every account. 2 All of which sup

plies further evidence that, when Congress wished to tie sanctions to account-level information, it knew exactly how to do so. Congress said that penalties for certain willful vio

lations may be measured on a per-account basis. Congress said that a person may invoke the reasonable cause exception only on a showing of per-account accuracy. But the one thing Congress did not say is that the government may im

pose nonwillful penalties on a per-account basis. Conspicu

ously, the one place in the statute where the government needs per-account language to appear is the one place it does not. In the end, the government's per-account theory faces not just a single expressio unius challenge but two. 3 The dissent founders on the same shoals. It suggests that the “pattern” of account-specifc language in the willful pen

alty provision and the reasonable cause exception “con

not[es]” that the nonwillful penalty provision must operate on a per-account basis. Post , at 107, 109–110 (opinion of **Barrett** , J.). But (again), just because two provisions in the law are similar does not mean we may ignore differences found in a third. Seeking a way around the problem, the

2 At argument, the government explained that the reasonable cause ex

ception works in this fashion to protect those who fle a late FBAR so long as the report they eventually fle accurately provides the required information. Tr. of Oral Arg. 57–58.

3 What if an individual (like Mr. Bittner) fails to fle a timely report and later fles an inaccurate one—would the statute classify that as two viola

tions of the duty to fle a statutorily compliant report rather than one? The parties do not join issue on the question and we do not pass upon it. Nor does the answer matter for present purposes. Either way, the stat

ute conditions nonwillful penalties on the number of reports, not on the number of accounts.96 BITTNER v. UNITED STATES Opinion of the Court dissent points to the fact that even a single qualifying for

eig n bank account “triggers” the duty to fle a report, and the fact that a compliant report must contain a “list of infor

mation” about bank addresses and the like. Post , at 105. These features of the law, the dissent says, “underscor[e]” that nonwillful violations accrue per account. Ibid . But that simply does not follow. The fact that a person has a duty to fle a report, or provide certain information in a re

port, does not tell us whether penalties for nonwillful viola

tions accrue per report or multiply per account without re

gard to an individual's net worth or foreign holdings. 4 B Widening our view beyond § 5314 and § 5321, we fnd other contextual clues pressing against the government's theory. Consider what the government itself has told the public about the BSA. In 2010, the Department of the Treasury issued a notice of proposed rulemaking warning that, under its proposed rules, “[a] person who is required to fle an FBAR and fails to properly fle may be subject to a civil penalty not to exceed $10,000.” 75 Fed. Reg. 8854 (2010). Elsewhere, the government has told suspected FBAR viola

tors that “[f]or the failure to fle . . . the penalty cannot ex

ceed $10,000.” IRS, Letter 3709, p. 1 (Mar. 2011). Instruc

tions included with the FBAR form have cautioned that “[a] person who is required to fle an FBAR and fails to properly fle may be subject to a civil penalty not to exceed $10,000.”

4 The dissent also stresses that 31 U. S. C. § 5314 imposes two duties—a duty to fle reports and keep records. Post, at 106. From this, the dis

sent reasons, “if violations of [the] recordkeeping obligation accrue on a per-account basis, the same should be true of violations of [the] obligation to fle reports.” Ibid . But the question whether violations of the recordkeeping duty accrue per account or on some other basis is not before us. Nor is it obvious why violations of two separate statutory duties must accrue in the same way—especially when the law authorizes the Secretary to “prescrib[e]” different “way[s]” the two duties may be discharged. § 5314(a).97 Cite as: 598 U. S. 85 (2023) Opinion of the Court IRS, Form TD F 90–22.1, p. 8 (Mar. 2011). An IRS “Fact Sheet” has advised that, “[f]or the FBAR, the penalty may be up to $10,000, if the failure to fle is non-willful.” IRS, Offshore Income and Filing Information for Taxpayers with Offshore Accounts, FS–2014–7 (June 2014). Ms. Boyd her

self received a similarly worded letter alerting her that “ `[f]or the failure to fle [the FBAR] . . . the penalty cannot exceed $10,000.' ” Boyd , 991 F. 3d, at 1085, n. 11 (alterations in original and emphasis deleted). None of these representations about the law's operation fts easily with the government's current theory. In all of these warnings, fact sheets, and instructions, the govern

ment seemed to tell the public that the failure to fle a report represents a single violation exposing a nonwillful violator to one $10,000 penalty. Nowhere in these materials did the government announce its current theory that a single def

cient or untimely report can give rise to multiple violations, that the number of nonwillful penalties may turn on the num

ber of accounts, or that the $10,000 maximum penalty may be multiplied 272 times or more without respect to an indi

vidual's foreign holdings or net worth. Doubtless, the government's guidance documents do not control our analysis and cannot displace our independent ob

ligation to interpret the law. But this Court has long said that courts may consider the consistency of an agency's views when we weigh the persuasiveness of any interpreta

tion it proffers in court. Skidmore v. Swift & Co. , 323 U. S. 134, 140 (1944). Here, the government has repeatedly is

sued guidance to the public at odds with the interpretation it now asks us to adopt. And surely that counts as one more reason yet to question whether its current position repre

sents the best view of the law. 5

5 The dissent expresses “surpris[e]” that we cite the government's guid

ance documents. Post , at 111. We don't see why. Our point is not that the administrative guidance is controlling. Nor is it that the govern

ment's guidance documents have consistently endorsed Mr. Bittner's read

-98 BITTNER v. UNITED STATES Opinion of the Court The drafting history of the nonwillful penalty provision under mines the government's theory too. When Congress adopted the BSA in 1970, the law included penalties only for willful violations and capped them at $1,000. § 125(a), 84 Stat. 1117. It took many years before Congress in 1986 au

thorized the government to impose penalties on a peraccount basis for certain willful violations. § 1357(c), 100 Stat. 3207–25. And it took many years more before Con

gress in 2004 amended the law again to authorize penalties for nonwillful violations. § 821(a), 118 Stat. 1586. When crafting this latest provision, it would have been the simplest thing for Congress to model its work on its 1986 amendment and authorize per-account penalties for nonwillful violations just as it had for certain willful ones. But Congress didn't do anything like that. The language it adopted for nonwill

ful penalties in 2004 bears scant resemblance to the language it used when authorizing per-account penalties for certain willful violations in 1986. Consider as well Congress's statement of purpose. Con

gress has declared that the BSA's “purpose” is “to require” certain “reports” or “records” that may assist the govern

ment in everything from criminal and tax to intelligence and counterintelligence investigations. 31 U. S. C. § 5311. 6 ing of the law. It is simply that, when the government (or any litigant) speaks out of both sides of its mouth, no one should be surprised if its latest utterance isn't the most convincing one. This is no new principle in the law any more than it is in life. In Skidmore , this Court noted that the persuasiveness of an agency's interpretation of the law may be undermined by its inconsistency “with earlier [agency] pronouncements.” 323 U. S., at 140.

6 “A preamble, purpose clause, or recital is a permissible indicator of meaning.” A. Scalia & B. Garner, Reading Law: The Interpretation of Legal Texts 217 (2012) (Scalia & Garner). See also 1 J. Story, Commen

taries on the Constitution of the United States § 459, p. 443 (1833) (“[T]he preamble of a statute is a key to open the mind of the makers, as to the mischiefs, which are to be remedied, and the objects, which are to be accomplished by the provisions of the statute”).99 Cite as: 598 U. S. 85 (2023) Opinion of the Court Here we see further evidence that the relevant legal duty the BSA establishes is the duty to fle certain reports. We see evidence, too, that the point of these reports is to supply the government with information potentially relevant to var

ious kinds of investigations, criminal and civil alike. But what we do not see is any indication that Congress sought to maximize penalties for every nonwillful mistake (whether a late fling, a transposed account number, or an out-of-date bank address). See Brief for American College of Trust and Estate Counsel as Amicus Curiae 5–7. 7 The Secretary's regulations implementing the BSA convey the same message. Under those regulations, individuals with fewer than 25 accounts must provide details about each account while those (like Mr. Bittner) with 25 or moreaccounts do not need to list each one or provide accountspecifc details about any of them. 31 CFR § 1010.350(g)(1). Instead, flers with 25 or more accounts “need only provide the number of fnancial accounts and certain other basic information.” Ibid . Naturally, an individual must sup

ply more “detailed information” if the “Secretary or his delegate” later chooses to follow up and request it. Ibid

. But no detailed account-level information is required in the fler's initial report. It's yet another feature of the BSA and its regulatory scheme that suggests the law aims to provide the government with a report suffcient to tip it to the need for further investigation, not to ensure the presentation of every detail or maximize revenue for each mistake.

7 The dissent insists that its per-account theory would better advance “the statute's purpose” of cracking down on criminals and terrorists. Post , at 112. But few statutes pursue their stated “ `purpose at all costs.' ” Kucana v. Holder, 558 U. S. 233, 252 (2010). Nor is it clear how calculat

ing nonwillful penalties on a per-account basis would advance the purpose the dissent attributes to the BSA. Are we to imagine that drug cartels and terrorists often make innocent mistakes when fling their FBARs?100 BITTNER v. UNITED STATES Opinion of the Court The Secretary's regulation also points to some of the anoma lies that accompany the government's per-account the

ory. On the government's telling, an individual with, say, three accounts who makes nonwillful errors when providing details about these accounts faces a potential penalty of $30,000. He faces that penalty no matter how slight his er

rors, and regardless whether his foreign holdings (or even net worth) approach the same amount. Meanwhile, a person with 300 bank accounts runs far less risk of incurring any penalty. He doesn't have to provide any detail about his accounts, just correctly disclose how many he holds. See also Brief for American College of Tax Counsel as Amicus Curiae 15–16 (Brief for Tax Counsel). Nor is this the only incongruity the government's theory invites. Consider someone who has a $10 million balance in a single account who nonwillfully fails to report that account. Everyone agrees he is subject to a single penalty of $10,000. Yet under the government's theory, another person engaging in the same nonwillful conduct with respect to a dozen for

eign accounts with an aggregate balance of $10,001 would be subject to a penalty of $120,000. Id ., at 14–15. On the government's view, too, those who willfully violate the law may face lower penalties than those who violate the law nonwillfully . For example, an individual who holds $1 million in a foreign account during the course of a year but withdraws it before the fling deadline and then willfully fails to fle an FBAR faces a maximum penalty of $100,000. But a person who errs nonwillfully in listing 20 accounts with an aggregate balance of $50,000 can face a penalty of up to $200,000. Id., at 14. Reading the law to apply nonwillful penalties per report invites none of these curiosities; the gov

ernment's per-account theory invites them all. 8

8 The dissent suggests that these examples bear “limited relevance” be

cause it is only “natura[l]” that a person “who violates the law many times” might incur more penalties. Post , at 112–113. But this assumes101 Cite as: 598 U. S. 85 (2023)

Opinion of **Gorsuch, J.** The government does not dispute any of this but replies that the per-report interpretation risks an anomaly of its own. After all, the government observes, the BSA affords the Secretary considerable discretion in formulating report

ing requirements. So much so, the government contends, that the Secretary could require a separate report for each account and in that way effectively achieve a per-account penalty for nonwillful violations. Brief for United States 32. But what does this prove? Assuming the Secretary could require more frequent reports (a question not before us), that would mean the Secretary could also require less fre

quent reports (for example, every other year). Likewise, the Secretary could reduce the amount of information re

quired in those reports (say, expanding the tick-box option to all flers, not just those with 25 or more accounts). Per

haps more fundamentally, whether the Secretary may law

fully ordain more or fewer reports does nothing to answer the question whether the Secretary may impose nonwillful penalties on a per-report or per-account basis. That ques

tion would still remain. Reply Brief 7–8. C To the extent doubt persists at this point about the best reading of the BSA, a venerable principle supplies a way to resolve it. Under the rule of lenity, this Court has long held, statutes imposing penalties are to be “construed strictly” against the government and in favor of individuals. Com

missioner v. Acker, 361 U. S. 87, 91 (1959). Following that rule here requires us to favor a per-report approach that would restrain BSA penalties over a per-account theory that would greatly enhance them. The government resists this conclusion by seeking to dis

tinguish Acker . That case involved a penalty provision in that violations accrue on a per-account basis, which begs the very question at issue before us.102 BITTNER v. UNITED STATES Opinion of **Gorsuch, J.** the Internal Revenue Code, the government emphasizes, wh ile this case involves a penalty provision in the BSA. Brief for United States 44–45. But that distinction makes no difference. The rule of lenity is not shackled to the Inter

nal Revenue Code or any other chapter of federal statutory law. Instead, as Acker acknowledged, “[t]he law is settled that penal statutes are to be construed strictly,” and an indi

vidual “is not to be subjected to a penalty unless the words of the statute plainly impose it.” 361 U. S., at 91 (internal quotation marks omitted and emphasis added). Notably, too, Acker cited to and relied on cases applying this same principle to penalty provisions under a wide array of stat

utes, including the Communications Act of 1934, a bank

ruptcy law, and the National Banking Act. See ibid. (citing FCC v. American Broadcasting Co. , 347 U. S. 284, 296 (1954); Keppel v. Tiffn Savings Bank , 197 U. S. 356, 362 (1905); and Tiffany v. National Bank of Mo. , 18 Wall. 409, 410 (1874)); see also Scalia & Garner 297 (the rule of lenity applies “to civil penalties”). Two additional features of this case make it a particularly appropriate candidate for the rule of lenity. First, the rule exists in part to protect the Due Process Clause's promise that “a fair warning should be given to the world in language that the common world will understand, of what the law in

tends to do if a certain line is passed.” McBoyle v. United States , 283 U. S. 25, 27 (1931); see also Connally v. General Constr. Co. , 269 U. S. 385, 393 (1926); Wooden v. United States , 595 U. S. –––, ––– – ––– (2022) ( **Gorsuch** , J., concur

ring in judgment). And the government's current theory poses a serious fair-notice problem. The relevant provisionsof the BSA nowhere discuss per-account penalties for nonwillful violations. A number of the government's own pub

lic guidance documents have seemingly warned of perreport, not per-account, penalties for nonwillful violations. See Part II–B, supra ; Brief for Tax Counsel 6–24. We are even told that, until 2008 and 2009, when the government103 Cite as: 598 U. S. 85 (2023) Opinion of the Court began aggressively enforcing FBAR penalties, “many expe

rienced tax professionals and return preparers were not aware of the FBAR reporting obligations,” let alone aware of the government's current theory about the scope of penal

ties for nonwillful violations. Brief for Center for Taxpayer Rights as Amicus Curiae 24, 20–28, and n. 21. If many ex

perienced accountants were unable to anticipate the govern

ment's current theory, we do not see how “the common world” had fair notice of it. McBoyle , 283 U. S., at 27. Second, the question before us has criminal as well as civil ramifcations. Section 5321 outlines civil penalties for nonwillful and willful “violation[s]” of the BSA. Next door, § 5322 provides criminal sanctions for “willfully violating” the Act. The term “violation” or “violating” is a constant between these two provisions. Accordingly, if the govern

ment were right that violations accrue on a per-account rather than a per-report basis under § 5321, the same rulewould apply under § 5322. Each willfully misstated or latereported account, rather than each defcient or late-fled re

port, would give rise to a separate criminal violation carry

ing the possibility of a $250,000 fne and fve years in prison. In a case like Mr. Bittner's, involving 5 reports and 272 ac

counts, that would mean a person who willfully violates the BSA could face a $68 million fne and 1,360 years in prison rather than a $1.25 million fne and 25 years in prison. In these circumstances, the rule of lenity, not to mention a dose of common sense, favors a strict construction. See Leocal v. Ashcroft , 543 U. S. 1, 12, n. 8 (2004) (lenity applies when a disputed statutory provision has “both criminal and noncrim

inal applications”); see also FCC, 347 U. S., at 296; United States v. Thompson/Center Arms Co. , 504 U. S. 505, 517–518 (1992) (plurality opinion). III Best read, the BSA treats the failure to fle a legally com

pliant report as one violation carrying a maximum penalty of $10,000, not a cascade of such penalties calculated on a104 BITTNER v. UNITED STATES **Barrett, J.** , dissenting per-account basis. Because the Fifth Circuit thought other

w ise, we reverse its judgment and remand the case for fur

ther proceedings consistent with this opinion. So ordered. **Justice Barrett** , with whom **Justice Thomas** , **Justice Sotomayor,**  and **Justice Kagan** join, dissenting. Alexandru Bittner, an American citizen, held as much as $16 million across more than 50 bank accounts in Romania, Switzerland, and Liechtenstein.* He acknowledges that the Bank Secrecy Act (BSA) and its implementing regulations required him to report his interest in these accounts to the Federal Government annually. Bittner also admits that he failed to comply with that requirement for fve consecutive years. Because he failed to report 272 accounts, the Gov

ernment concluded that he violated the law 272 times and assessed a penalty for each violation. Bittner, on the other hand, argued that he violated the law just fve times—once for each annual form that he failed to fle. The Court agrees with Bittner and holds that the failure to fle a legally compliant form is a single violation, no matter how many accounts a citizen fails to report. I respectfully disagree. The most natural reading of the statute estab

lishes that each failure to report a qualifying foreign account constitutes a separate reporting violation, so the Govern

ment can levy penalties on a per-account basis. I This case requires us to decide whether a violation of the BSA's reporting requirement is the failure to fle an annual form, or whether there is a separate violation for each indi

-

*In 2007, for example, he held over $10 million across 61 foreign bank accounts. The pattern continued: $10 million across 51 accounts in 2008, $3 million across 53 accounts in 2009, $16 million across 53 accounts in 2010, and $15 million across 54 accounts in 2011.105 Cite as: 598 U. S. 85 (2023)

**Barrett, J.** , dissenting vidual account that is not properly reported. The answer l ies in the text of the relevant statutes, 31 U. S. C. §§ 5314 and 5321. The Government assessed penalties against Bitt

ner under § 5321(a)(5)(A), which provides that “[t]he Secre

tary of the Treasury may impose a civil money penalty on any person who violates, or causes any violation of, any pro

vision of section 5314.” Section 5314, in turn, directs the Secretary to “require a . . . citizen of the United States . . . to keep records, fle reports, or keep records and fle reports, when the . . . person makes a transaction or maintains a relation for any person with a foreign fnancial agency.” § 5314(a). The required “records and reports shall contain” certain information “in the way and to the extent the Secre

tary prescribes,” such as the identity, address, and legal capac

ity of the participants in a transaction or relationship. Ibid

. The text of § 5314 indicates that its reporting requirement attaches to each individual account. Most notably, it pro

vides that the Secretary “shall require” a citizen to “fle re

ports” when he “maintains a relation . . . with a foreign f

nancial agency.” Ibid . The subject matter of the required reports, then, is “a relation” with a foreign fnancial agency— or, more colloquially, an account with a foreign bank. Ibid

. In other words, each relation with a foreign bank triggers the requirement to fle reports. And because each relation is a matter of distinct concern under the statute, each failure to report an account violates the reporting requirement. The enumerated list of information that the reports “shall contain” underscores the point. Ibid . That list includes in

formation like “the identity and address of participants in a . . . relationship,” “the legal capacity in which a participant” in a relationship “is acting,” and “the identity of real parties in interest.” §§ 5314(a)(1)–(3). Each listed item is account specifc because its contents can vary for each foreign ac

count held. And each failure to report an account thus de

prives the Government of the account-specifc information that the statute requires.106 BITTNER v. UNITED STATES **Barrett, J.** , dissenting That is not all. Section 5314 authorizes the Secretary to i mpose a recordkeeping requirement in addition to a report

ing requirement. Recordkeeping violations cannot occur on a per-form basis because keeping records does not entail fl

ing a form. Instead, they occur on a per-account basis be

cause records naturally relate to specifc accounts. And if violations of § 5314's recordkeeping obligation accrue on a per-account basis, the same should be true of violations of § 5314's obligation to fle reports. The duties are parallel: Each kicks in “when” a citizen “maintains a relation” with a foreign fnancial agency, and each requires a person to collect the same account-specifc information. § 5314(a). Parallel duties should be susceptible to parallel violations. The civil penalty provisions in § 5321 confrm this reading of the substantive obligations imposed by § 5314. Recall that § 5321 allows the Secretary to “impose a civil money penalty on any person who violates, or causes any violation of, any provision of section 5314.” § 5321(a)(5)(A). Thestatute then proceeds to set the maximum penalty for nonwillful violations, provide a reasonable cause exception for those same violations, and set the maximum penalty for will

ful violations. §§ 5321(a)(5)(B)–(D). Throughout, Congress used the term “violation” in an account-specifc way. Consider the reasonable cause exception. It provides that“[n]o penalty shall be imposed . . . with respect to any” nonwillful “violation” of § 5314 if (1) “such violation was due to reasonable cause” and (2) “the balance in the account at the time of the transaction was properly reported.” § 5321(a) (5)(B)(ii) (emphasis added). By conditioning eligibility for the excuse on taking steps to report accurate information about a particular account, this language suggests that the underlying violation of § 5314 is similarly tied to a specifc account. After all, “if the exception for non-willful viola

tions applies on a per-account basis, then logically the viola

tions the exception forgives must arise on a per-account basis too.” 19 F. 4th 734, 747–748 (CA5 2021).107 Cite as: 598 U. S. 85 (2023)

**Barrett, J.** , dissenting The willful penalty provisions sing the same tune. The maxi mum penalty for a willful violation is the greater of $100,000 or, “in the case of a violation involving a failure to report the existence of an account or any identifying infor

mation required to be provided with respect to an account,” 50 percent of “the balance in the account at the time of the violation.” §§ 5321(a)(5)(C)(i), (D)(ii). “This language makes clear that a violation may involve `a failure to report the existence of' ” a particular account. United States v. Boyd , 991 F. 3d 1077, 1089 (CA9 2021) (Ikuta, J., dissenting). By making the maximum penalty for a willful violation in some cases a function of “the balance in the account at the time of the violation,” the provision contemplates that discrete violations correspond to discrete accounts. § 5321(a)(5)(D)(ii). This pattern matters. The “normal rule of statutory in

terpretation” is that “identical words used in different parts of the same statute are generally presumed to have the same meaning.” IBP, Inc. v. Alvarez , 546 U. S. 21, 34 (2005). If a “violation” of § 5314 has account-specifc connotations in the reasonable cause and willful penalty provisions, it follows that a “violation” of § 5314 has account-specifc connotations when it comes to nonwillful penalties too. The Secretary's implementing regulations follow the BSA's lead. They require regulated persons to report the existence of each foreign fnancial account to the Government each year. Start with 31 CFR § 1010.350 (2011). It says that “[e]ach United States person having a fnancial interest in . . . a bank, securities, or other fnancial account in a for

eign country shall report such relationship to the Commis

sioner of Internal Revenue for each year in which such rela

tionship exists and shall provide such information as shall be specifed in a reporting form prescribed under 31 U. S. C. 5314 to be fled by such persons.” § 1010.350(a) (emphasis added). The reporting form is known as an FBAR—a Re

port of Foreign Bank and Financial Accounts. Ibid . A sep

-108 BITTNER v. UNITED STATES **Barrett, J.** , dissenting arate regulation establishes the deadline for reporting these relati onships. “Reports required to be fled by § 1010.350 shall be fled” by “June 30 of each calendar year with re

spect to foreign fnancial accounts exceeding $10,000 main

tained during the previous calendar year.” § 1010.306(c), as amended, 81 Fed. Reg. 76864 (2016). Put together, these provisions impose a substantive obligation to report inter

ests in foreign bank accounts each year in which those inter

ests exist. See § 1010.420 (referring to “accounts required by § 1010.350 to be reported to the” Government). Notably, the regulations distinguish between the form used to report accounts and the reports themselves. See § 1010.306(d) (the “[r]eports required by” § 1010.350 “shall be fled on forms prescribed by the Secretary” (emphasis added)); § 1010.306(e) (the “[f]orms to be used in making the reports required by” § 1010.350 “may be obtained from” the Government (emphasis added)). This underscores that FBAR forms are not themselves the “reports” required by the statute; rather, they are the procedural mechanism used to implement the duty to report each foreign account. This distinction tracks § 5314, which emphasizes a citizen's duty to fle “reports” but nowhere mentions FBARs—or, for that matter, forms of any sort. § 5314(a). So far as § 5314 is con

cerned, the Secretary could have chosen a different mecha

nism to implement the statute. For instance, rather than instructing citizens to report all accounts on a single form, he could have instructed citizens to report each account on a separate form. And if the Secretary had taken that route, Bittner would be hard pressed to deny that he would have violated the statute 272 times by failing to fle 272 forms. That diffculty illustrates Bittner's fundamental misunder

standing of the account-specifc obligation imposed by § 5314, which is indifferent to the mechanism by which the obliga

tion is discharged. In the end, “the applicable statute and regulations make clear that any failure to report a foreign account is an inde

-109 Cite as: 598 U. S. 85 (2023)

**Barrett, J.** , dissenting pendent violation, subject to independent penalties.” Boyd , 991 F. 3d, at 1089–1090 (Ikuta, J., dissenting). A person who fails to report multiple foreign accounts on a single annual form violates the BSA and its implementing regulations multi

ple times, not just once. So the Government was within its rights to assess a separate penalty against Bittner for each qualifying foreign account that he failed to report properly. II A The Court reads the relevant provisions differently. It reasons that the legal duty imposed by § 5314 is “the duty to fle reports.” Ante , at 92. In the Court's view, that “statu

tory obligation is binary”: “Either one fles a report `in the way and to the extent the Secretary prescribes,' or one does not.” Ante , at 93. So penalties for nonwillful violations must “accrue on a per-report, not a per-account, basis.” Ante , at 94. And because Bittner failed to fle timely FBARs for fve years, the Court concludes that he violated the law only fve times. The Court's core error is to confate the reports referred to in § 5314 with the annual FBAR form . To reiterate, the two are distinct. And because the FBAR is not itself the statutorily required “report,” the Court's conclusion—that Bittner violated § 5314 just fve times because he untimely fled fve FBAR forms—does not follow. The BSA and its implementing regulations required Bittner to fle one report per year of each qualifying foreign fnancial account that he maintained. Each failure to report an account is a discrete violation regardless of whether the violations were clustered on a single form. The Court does not just misread § 5314; it misreads § 5321 too. It points out that account-specifc language is present in the reasonable cause and willful penalty provisions but absent in the provisions setting the nonwillful penalty. Be

cause “Congress generally acts intentionally when it uses110 BITTNER v. UNITED STATES **Barrett, J.** , dissenting particular language in one section of a statute but omits it i n another,” Department of Homeland Security v. MacLean , 574 U. S. 383, 391 (2015), the Court takes the contrast asevidence that nonwillful penalties cannot apply on a peraccount basis. Ante , at 94–95 (invoking the expressio unius canon). Not so. The expressio unius canon is a general rule, in

applicable where context suggests otherwise—as it does here. Congress capped the penalty for a nonwillful violation at a fat $10,000. § 5321(a)(5)(B)(i). Because the penalty amount does not depend on the balance in an account, Con

gress had no reason to use account-specifc language. By contrast, the maximum penalty for a willful violation is the greater of $100,000 or 50 percent of the account balance at the time of the violation, and the reasonable cause exception lifts a penalty only if the account balance was properly re

ported. §§ 5321(a)(5)(B)(ii), (C)(i), (D)(ii). Because the ap

plication of both provisions depends on the account balance , Congress needed to use account-specifc language. The rea

son why Congress included account-specifc language in only two of these three provisions is therefore readily apparent. Regardless, the variation in language does not do much for the Court. These provisions in § 5321 explain the vary

ing penalties that the Secretary may assess for a violation of § 5314 but do not alter the nature of the underlying con

duct that constitutes a violation

. Boyd , 991 F. 3d, at 1089 (Ikuta, J., dissenting). That conduct, as discussed, is ac

count specifc. B The Court also invokes a handful of “contextual clues” to support its conclusion. Ante , at 96. None of these “clues” justifes a departure from the best reading of the text. Begin with the Government's guidance to the public about what the BSA requires. The Court identifes a handful of statements, primarily from Internal Revenue Service (IRS) fact sheets and form instructions, indicating that a failure to111 Cite as: 598 U. S. 85 (2023)

**Barrett, J.** , dissenting fle an annual FBAR may result in a penalty of up to $10,000. The Court acknowledges that these materials do not control the analysis, yet it still goes on to suggest that they cut against the Government's interpretation. Ante , at 96–97. I am surprised that the Court is moved by this administra

tive guidance. For one thing, even Bittner concedes that the materials do not speak directly to the question presented in this case: whether additional penalties may accrue when a person fails to report multiple accounts on a single form. Reply Brief 18; Tr. of Oral Arg. 39–40. For another, the Court neglects to mention administrative materials that en

dorse the Government's per-account interpretation. See, e. g. , Brief for American College of Tax Counsel as Amicus Curiae 18, 21 (identifying IRS staff guidance materials from 2008 and 2015 explaining that FBAR penalties may be as

sessed per account). But in any event, guidance materials add little, if anything, to the interpretive enterprise when the traditional tools of construction supply an answer. The Court also highlights the Secretary's regulatory deci

sion to allow the rare covered person with 25 or more foreign fnancial accounts to “only provide the number of fnancial accounts and certain other basic information on the report.” § 1010.350(g)(1). According to the Court, this special rule is a knock against the Government's reading because it does not require detailed account-level information in such a fler's initial report. Ante , at 99. But the Secretary's accommodation does not advance the Court's cause. A person with 25 or more accounts still “will be required to provide detailed information concerning each account when so requested by the Secretary or his delegate.” § 1010.350(g)(1). And the Secretary's recordkeeping regula

tion requires covered persons to retain the same detailed information about each account that otherwise would be re

ported on the annual form. See § 1010.420. So a person with 25 or more accounts violates the BSA for each account with a reporting or recordkeeping problem just the same as112 BITTNER v. UNITED STATES **Barrett, J.** , dissenting a person with fewer than 25 accounts. In both cases, the v iolation is the failure to report the account properly or to keep records of it. That consequence is consistent with the statute's purpose. In arguing otherwise, the Court leans on what the preamble does not say: “[T]hat Congress sought to maximize penal

ties for every nonwillful mistake.” Ante , at 99. Notably, though, the Court skims over what the preamble does say: that the BSA is designed to “require certain reports or rec

ords” that assist the Government in “criminal, tax, or regula

tory investigations” and in “intelligence or counterintelli

gence activities, including analysis, to protect against terrorism.” 31 U. S. C. § 5311(1). When analyzing complex webs of money laundering or funding for international ter

rorism, knowing about every account matters—and lacking information about 15 accounts is certainly more harmful to law enforcement than lacking information about 1 account. See Brief for United States 38. Given the stated purpose, authorizing a penalty for each undisclosed account makes sense. Finally, the Court insists that a per-account reading leads to absurd results. Its concerns range from the overstated to the incorrect, and they are in any event of limited rele

vance to the statutory interpretation question before us. First, the Court posits a comparison between a person who nonwillfully violates the law once by failing to report a singleaccount with a balance of $10 million and a person who nonwillfully violates the law 12 times by failing to report 12 accounts with an aggregate balance of $10,001.

**Barrett, J.** , dissenting in their unreported accounts. Indeed, the Court seems un

troubled by the incongruity that fows from its own reading: The Secretary is constrained by the same maximum penalty ($10,000) for a person who nonwillfully fails to report 100accounts on an annual FBAR as he is for a person who nonwillfully fails to report just 1 account. The per-form read

ing makes it diffcult for the Government to assess stiffer penalties for more serious noncompliance. Consider next the Court's claim that, on the Government's reading, those who willfully violate the law may face lower penalties than those who nonwillfully violate the law. Ibid

. The Court provides the example of a person who holds $1 million in a foreign account during the course of a year but withdraws those funds before the fling deadline and willfully fails to report the account. Under § 5321(a)(5)(C), that per

son faces a maximum penalty of $100,000, while a person who nonwillfully fails to report 20 accounts with an aggregate account balance of $50,000 might face a penalty of up to $200,000 under § 5321(a)(5)(B)(i). This is not an apples-to

apples comparison: The frst person willfully violated the law once, while the second nonwillfully violated the law 20 times. That the latter might face a higher penalty than the former is therefore beside the point. An actual apples-to-apples comparison shows that willful violators do face a much heav

ier fne: The maximum penalty for a single willful violation will always be at least 10 times greater than the maximum penalty for a single nonwillful violation. See §§ 5321(a) (5)(B)(i), (C)(i). III There is no denying that the Government opted to pursue a substantial penalty in this case: $10,000 for each of Bitt

ner's 272 alleged violations, for a total penalty of $2.72 mil

lion. Yet while the statutory scheme allows for substantial penalties, it also offers a safe haven. No penalty shall be imposed for a nonwillful violation of § 5314 if (1) “such viola

ported.” § 5321(a)(5)(B)(ii). Bittner raised this defense below, and the Government conceded that he satisfed its second prong by properly re

porting the balances in his accounts on his late-fled FBARs. 19 F. 4th, at 740, and n. 2. But the District Court and Court of Appeals both roundly rejected Bittner's argument that he had reasonable cause for failing to timely report his accounts. After evaluating the pertinent facts and circumstances, both courts concluded that Bittner “did not exercise ordinary business care and prudence in failing to fulfll his reporting obligations.” Id ., at 742; see also 469 F. Supp. 3d 709, 729 (ED Tex. 2020). On the contrary, Bittner “put no effort into ascertaining” those obligations despite operating as a sophis

ticated business professional who held “interests in dozens of companies, negotiated purchases of Romanian government assets, transferred his assets into holding companies, and concealed his earnings in `numbered accounts.' ” 19 F. 4th, at 742. Bittner abandoned his reasonable cause argument when he came to this Court, so we have no occasion to con

sider its merit. Brief for Petitioner 11, n. 9. But the de

fense is available to litigants who can satisfy it. * * * The most natural reading of the BSA and its implementing regulations establishes that a person who fails to report mul
