Wire Fraud Defense (18 U.S.C. § 1343)

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

Wire fraud is the most frequently charged white-collar offense in the federal system. The statute is written so broadly that prosecutors use it to reach almost any scheme involving deception and an email, a phone call, or an electronic transfer. A wire fraud indictment can carry decades of potential prison time and dozens of counts built from a single course of conduct. If you are under investigation or charged, a wire fraud lawyer should examine the government’s theory closely and early.

We are Elizabeth Franklin-Best, P.C., a federal criminal defense and appellate firm, and defending wire fraud prosecutions under § 1343 sits at the center of what we do. Elizabeth Franklin-Best practices exclusively in federal courts and agencies; Best Lawyers in America recognizes her as its 2026 “Best Lawyer” in Appellate Practice, and Chambers USA ranks her in its 2026 guide for Litigation: White-Collar Crime & Government Investigations. Wire fraud is an intent crime with real doctrinal limits — limits the Supreme Court has redrawn more than once since 2023 — and we build defenses around every one of them.

Below, we cover the statute’s text, each element the government must prove, the Supreme Court’s recent narrowing decisions, the penalty and Guidelines picture, and the defenses that actually move cases. Nothing on this page is legal advice for your specific situation — for that, we offer a paid, one-hour initial consultation. The guide belongs to our federal fraud defense practice area.

Key Takeaways

• Wire fraud is the federal government’s most versatile fraud charge, reaching almost any deceptive scheme that touches an interstate wire.
• The crime requires a specific intent to defraud — a deliberate plan to deceive, not a mistake, a bad result, or an honest business judgment.
• The misrepresentation must be material, and the object of the scheme must be money or property.
• The wire communication itself does not have to be false — it only has to be used in furtherance of the scheme.
• Because each qualifying wire can be a separate count, a single scheme can produce a multi-count indictment with enormous cumulative exposure.
• Honest-services wire fraud is limited to bribery and kickback schemes; the Supreme Court narrowed it to prevent the theory from sweeping too broadly.
• Between 2023 and 2025 the Supreme Court rejected the right-to-control theory (Ciminelli) but approved fraudulent-inducement prosecutions (Kousisis) — making materiality the decisive battleground in many cases.
• Good faith is a complete defense — if the defendant honestly believed the representations were true, there is no wire fraud.

What Is Wire Fraud?

Wire fraud is a scheme to obtain money or property through deception, carried out with the help of an interstate or international wire communication. The “wire” can be almost anything electronic — an email, a text message, a phone call, a fax, an electronic funds transfer, or activity over the internet. Because nearly every modern transaction involves at least one such communication, wire fraud has become the federal prosecutor’s default charge for deceptive conduct of every kind.

That versatility makes wire fraud both common and dangerous. It is used to prosecute investment schemes, business disputes that the government recasts as crimes, employee misconduct, romance and online scams, procurement matters, and much more. But the breadth of the statute does not lower the government’s burden. Wire fraud is a specific-intent crime. The prosecution must still prove a genuine scheme to defraud, a deliberate intent to deceive, and a material misrepresentation — and each of those requirements gives a defense room to work.

The Wire Fraud Statute: 18 U.S.C. § 1343

Wire fraud is defined in 18 U.S.C. § 1343. The statute punishes anyone who, “having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises,” transmits or causes to be transmitted “by means of wire, radio, or television communication in interstate or foreign commerce” any writing, sign, signal, picture, or sound for the purpose of executing the scheme.

The wire fraud statute is the close sibling of the mail fraud statute, 18 U.S.C. § 1341. The two are interpreted in tandem and share the same core concept of a “scheme or artifice to defraud”; they differ mainly in the jurisdictional hook — interstate wires for one, the mails for the other. Prosecutors often charge both. The Supreme Court has read the statute’s disjunctive language — “scheme to defraud” and “obtaining money or property” — as a unified whole, so that the money-or-property requirement limits the entire statute.

What the Government Must Prove

To convict of wire fraud, the government must prove each of the following beyond a reasonable doubt:

• A scheme to defraud. The defendant devised, or intended to devise, a scheme to obtain money or property by deception.
• Intent to defraud. The defendant participated in the scheme knowingly and with the specific intent to deceive or cheat.
• Materiality. The false or fraudulent representations were material — capable of influencing the decision of the person they were directed to.
• Use of an interstate wire. The defendant used, or caused the use of, an interstate or international wire communication.
• In furtherance of the scheme. The wire communication was used for the purpose of executing, or in furtherance of, the scheme.

Several points within those elements are commonly misunderstood. The wire communication itself does not have to be false or fraudulent — an entirely innocent email can satisfy the element if it helped carry out the scheme. The defendant need not have personally sent the wire, as long as the use of a wire was reasonably foreseeable. And the scheme does not have to succeed; wire fraud punishes the scheme and the intent, so a loss is not required for conviction. What the government cannot avoid proving is intent. The defendant must have acted with a deliberate purpose to deceive.

Applied insight. Wire fraud cases are won and lost on intent. The emails and transfers usually are not in dispute — what they mean is. A defense keeps the jury’s attention on whether the defendant set out to deceive, because optimism, error, reliance on advisers, and ordinary hard-nosed dealing are not crimes, however badly a venture later turned out.

The Money or Property Requirement

One of the most important limits on wire fraud is that the object of the scheme must be money or property. The Supreme Court has enforced that limit repeatedly, and the boundary lines are now well marked. Confidential business information counts as property — that has been settled since Carpenter v. United States, 484 U.S. 19 (1987), where trading on a newspaper column’s prepublication contents supported a fraud conviction. But a government’s regulatory choices do not. In Kelly v. United States, 590 U.S. 391 (2020), the Court threw out the “Bridgegate” convictions because realigning traffic lanes was an exercise of sovereign power, not a taking of property, and the public employees’ time spent implementing the decision was only an incidental byproduct of the scheme rather than its object.

The most consequential recent ruling is Ciminelli v. United States, 598 U.S. 306 (2023). For decades, prosecutors in the Second Circuit had charged wire fraud on a “right to control” theory — the idea that depriving a victim of potentially valuable economic information needed to make discretionary economic decisions was itself a property fraud. A unanimous Court rejected that theory outright: the right to make informed decisions about one’s assets, standing alone, is not a traditional property interest, so it cannot be the object of a § 1343 scheme. Any indictment, jury instruction, or government summation built on deprivation-of-information language is now vulnerable, and testing whether the charged scheme truly targeted money or property is core defense work in every wire fraud case we handle.

Applied insight. The money-or-property element is more than a technicality — it is a live defense. The Supreme Court has narrowed wire fraud more than once in recent terms. A theory that would have survived a decade ago may not survive today, which makes a careful look at what the alleged scheme was designed to obtain essential.

How Kousisis, Neder, and Thompson Shape the Defense Playbook

If Ciminelli trimmed the statute, Kousisis v. United States, 605 U.S. 114 (2025), confirmed how much remains. The defendants there won PennDOT painting contracts by falsely certifying compliance with a disadvantaged-business participation requirement, then delivered the bridge work itself at full value. The Court upheld the convictions: a defendant who induces a victim to enter a transaction through materially false pretenses can commit wire fraud even when the victim suffers no net economic loss. Fraudulent inducement is a valid theory, and an economic-loss requirement cannot be read into § 1343.

Kousisis did not leave the theory unbounded — it pointed to materiality as the principal check. That makes Neder v. United States, 527 U.S. 1 (1999), more important than ever. Neder holds that materiality is an implied element of the mail, wire, and bank fraud statutes, and a misstatement is material only if it has a natural tendency to influence, or is capable of influencing, the decision of the person to whom it was addressed. After Kousisis, the decisive fight in an inducement case is usually whether the alleged lie went to the essence of the bargain or to something the counterparty would have shrugged off. Neder cuts both ways, though: it also confirms that actual reliance and damages are not elements, so the absence of a victim who lost money will not, by itself, defeat the charge.

A third recent decision supplies a different lever. In Thompson v. United States, 604 U.S. 408 (2025), the Court held that 18 U.S.C. § 1014, which criminalizes false statements to banks, does not reach statements that are misleading but literally true — “false” means false. Thompson construed a different statute, but its method matters here: it signals that the current Court reads fraud-adjacent statutes by their text, and it gives the defense a principled basis to press the line between a literal falsehood and an incomplete or slanted truth when litigating instructions and sufficiency.

These decisions translate into concrete motion practice. In a current wire fraud defense, we look at each of the following:

• Motions to dismiss where the indictment describes the object of the scheme as information, transparency, or decision-making power rather than money or property under Ciminelli.
• Instruction battles over the materiality definition — insisting the jury be told it must find the misrepresentation went to the substance of the transaction, not a collateral detail.
• Rule 29 motions arguing the proof showed only truthful-but-incomplete statements, optimistic projections, or puffery rather than a material falsehood.
• Preservation for appeal, because this corner of the law has moved three times in three terms and convictions built on yesterday’s theories keep getting unwound.

Honest-Services Wire Fraud

There is one branch of wire fraud that does not depend on a loss of money or property. Under 18 U.S.C. § 1346, a “scheme or artifice to defraud” includes a scheme to deprive another of “the intangible right of honest services.” This is the theory used to prosecute corrupt employees, executives, and public officials who betray a duty owed to an employer or the public.

Honest-services fraud once threatened to become limitless, and the Supreme Court reined it in. In Skilling v. United States, 561 U.S. 358 (2010), the Court construed § 1346 to reach only bribery and kickback schemes — not undisclosed self-dealing or conflicts of interest more generally — precisely to keep the statute from being unconstitutionally vague. That limit is significant: if the government’s honest-services theory does not rest on an actual bribe or kickback, it may not fit the statute at all. The Court tightened the screws again in Percoco v. United States, 598 U.S. 319 (2023), holding that the instructions used to convict a private citizen — turning on whether he wielded informal “domination and control” over a government decision — were too vague to sustain the conviction. Together, Skilling and Percoco keep § 1346 tethered to a genuine quid pro quo, and the precise duty a private actor owes the public remains unsettled and worth contesting. Honest-services prosecutions overlap heavily with our public corruption defense practice.

Penalties for Wire Fraud

Wire fraud is a felony. The base statutory maximum is 20 years in prison per count. That maximum rises sharply — to 30 years, with a fine of up to $1 million — when the scheme affects a financial institution or is connected to a federally declared major disaster or emergency. Each qualifying wire can be charged as its own count, so an indictment arising from one scheme can stack many counts and a very large theoretical exposure.

The statutory maximum, however, is rarely the operative number. The actual sentence is driven by U.S.S.G. § 2B1.1, the fraud guideline, and its dominant variable is loss — the greater of the actual or intended loss the scheme caused. Effective November 1, 2024, the Sentencing Commission moved the intended-loss rule from the commentary into the guideline text itself (Amendment 827), settling a circuit fight and confirming that a scheme’s unrealized ambitions can set the offense level. Enhancements layer on from there: victim counts, sophisticated means, role in the offense, and abuse of a position of trust. A conviction also carries mandatory restitution and forfeiture of proceeds. Because a contested loss figure can swing the advisory range by years, our federal sentencing practice treats the loss computation as a case within the case.

Applied insight. A multi-count wire fraud indictment can look overwhelming, but counts are not the same as exposure. Each count reflects a wire, not a separate harm, and the sentence is driven by one loss figure, not the count total. Reframing a 30-count indictment around its actual loss number is often the first step toward a realistic defense.

Counts, Wires, and the Statute of Limitations

The unit of prosecution for wire fraud is the wire, not the scheme. Every interstate transmission made in furtherance of the scheme — each email, each transfer, each call — can stand as its own count, which is why one alleged fraud so often becomes a twenty-count indictment. That charging structure creates defense opportunities. Counts that slice a single transmission into several charges may be multiplicitous, and at sentencing the Guidelines group fraud counts together, so the count total rarely moves the advisory range. We attack the architecture of the indictment as well as its substance.

Which wires actually qualify is a litigated question. Under Schmuck v. United States, 489 U.S. 705 (1989) — decided under the mail fraud statute and applied by the courts to wires as well — the transmission need not be essential to the scheme or itself contain anything false; it is enough that it was incident to an essential part of the scheme or a step in the plot. Routine, innocent communications qualify. So do “lulling” messages sent after the money changed hands to reassure victims, keep the scheme running, or delay discovery. But the doctrine has an end point: once a scheme has reached fruition, communications that amount to nothing more than post-fraud accounting among the victims are not in furtherance of anything. Counts built on after-the-fact wires deserve close scrutiny, and so does the limitations math that depends on them.

Nor must the defendant have touched a keyboard. Under Pereira v. United States, 347 U.S. 1 (1954), a defendant “causes” a wire when its use follows in the ordinary course of business or was reasonably foreseeable, even if never intended. For clients on the periphery of a venture, foreseeability is a genuine trial issue — knowing about a business is not the same as foreseeing the specific transmissions the government charges.

Timing rounds out the analysis. The default limitations period for wire fraud is five years under 18 U.S.C. § 3282, but it stretches to ten years under 18 U.S.C. § 3293 when the offense “affects a financial institution” — the same trigger that raises the statutory maximum to 30 years. Prosecutors read “affects” aggressively, invoking it whenever a bank appears anywhere in the money flow. Courts have generally required more: actual loss, or at least a new or increased risk of loss, to the institution itself. Whether the ten-year window genuinely applies is often worth a fight, because it can erase the oldest — and frequently the most prejudicial — conduct from the case.

Defending a Wire Fraud Case

The strongest wire fraud defense is usually the absence of intent. Wire fraud requires a specific intent to defraud, and good faith is a complete defense. If the defendant honestly believed the representations were true, relied in good faith on lawyers or accountants, disclosed the relevant risks, or simply made an honest business misjudgment, there is no wire fraud — no matter how much money was ultimately lost. A great many wire fraud prosecutions are really business disputes, failed ventures, or aggressive but lawful dealing that the government has recast in criminal terms.

Other defenses target the remaining elements. The defense may show that there was no scheme to defraud, that any misstatement was immaterial or mere puffery, that the object of the alleged scheme was not money or property, or that the wire was not interstate or was not used in furtherance of the scheme. Where the government proceeds on an honest-services theory, the absence of an actual bribe or kickback can defeat the charge. The statute of limitations and the loss calculation are also fair targets. We work through the documentary record in detail, test each element, and account for the most recent limits the Supreme Court has placed on the statute. No lawyer can guarantee a result, and we never claim otherwise; what we promise is rigor — every element examined, every weak count challenged, every appellate issue preserved.

Why Work With Elizabeth Franklin-Best, P.C.

Our firm defends wire fraud cases from grand jury investigation through trial, sentencing, and appeal — anywhere in the federal system. Elizabeth Franklin-Best is admitted to the bar of the United States Supreme Court and all twelve federal circuit courts of appeals, and she appears in district courts across the country through pro hac vice admission. Her work has earned the 2026 “Best Lawyer” designation in Appellate Practice from Best Lawyers in America and a Chambers USA 2026 ranking in Litigation: White-Collar Crime & Government Investigations.

The record behind that recognition runs deep. Over the course of her career, Ms. Franklin-Best has appeared in more than 330 federal matters — better than 100 of them appeals — and has carried cases into every one of the twelve federal circuits and to the United States Supreme Court at the certiorari stage. She is the author of Reversing Your Criminal Conviction, and her practice is built on the parts of a fraud case that decide it: the indictment’s legal theory, the jury instructions, the loss calculation, and the appellate issues that have to be preserved while the trial is still underway. Past results never guarantee a future one, and we do not suggest otherwise; what this depth of experience buys a client is judgment about which fights in a § 1343 case are worth having.

That appellate grounding matters in a § 1343 case more than almost anywhere else, because the controlling doctrine keeps shifting — Ciminelli, Kousisis, and Thompson all arrived within three terms. We track those decisions as they come down, argue them in district court before the pattern instructions catch up, and preserve the issues that win on appeal. Every representation starts with the documents and the client, not a template: we reconstruct the transactions ourselves and shape a defense to the facts we actually find. This guide is one piece of our broader federal fraud defense practice.
