18 U.S.C. § 1960 makes it a federal felony to run an unlicensed money transmitting business, punishable by up to five years in prison per count. The statute reaches three distinct kinds of conduct: operating without a required state license, failing to register with the Financial Crimes Enforcement Network (FinCEN), and knowingly moving funds tied to criminal activity. Prosecutors use it against everything from storefront check cashers to peer-to-peer cryptocurrency traders, and the knowledge element is narrower than most defendants assume.
The Three Prongs of the Offense
Section 1960 defines an “unlicensed money transmitting business” through three independent theories. The government only has to prove one.1Office of the Law Revision Counsel. 18 U.S. Code 1960 – Prohibition of Unlicensed Money Transmitting Businesses
The first prong covers operating in a state that requires a money transmitter license and treats unlicensed operation as a misdemeanor or felony. The statute says the defendant does not need to have known that a license was required. If the state requires one and you don’t have it, that element is met.
The second prong covers failing to register with FinCEN as required under 31 U.S.C. § 5330 and its implementing regulations. Every money services business operating in the United States must register, whether or not the home state imposes its own licensing regime.
The third prong covers transmitting money the operator knows came from criminal activity or is intended to fund illegal conduct. This reaches operators who might hold valid licenses but knowingly move dirty money.
The business must also affect interstate or foreign commerce. Courts read that requirement broadly enough that funds crossing state lines, use of the banking system, or transactions over the internet all satisfy it.
What Prosecutors Actually Have to Prove
The government must prove the defendant “knowingly” conducted, controlled, managed, or owned the money transmitting business. The knowledge element sounds like a serious hurdle. It usually isn’t.
Knowledge of Facts, Not of the Law
For the state-license prong, the statute explicitly says conviction does not require proof that the defendant knew a license was required or that operating without one was a crime.1Office of the Law Revision Counsel. 18 U.S. Code 1960 – Prohibition of Unlicensed Money Transmitting Businesses Congress added that language in 2001 to shut down ignorance-of-the-law defenses. The Fourth Circuit confirmed the reading in United States v. Talebnejad, treating § 1960 as a general intent crime that requires knowledge only of the factual elements: that you were running a money transmitting business affecting interstate commerce. Knowing the activity was illegal is not required.2Justia. United States v. Talebnejad, 460 F.3d 563
The FinCEN-registration prong works the same way. Under Talebnejad, the government must prove the defendant knew the factual elements of the business but does not need to prove awareness of the registration requirement itself.2Justia. United States v. Talebnejad, 460 F.3d 563
The criminal-funds prong is different. There, the government has to prove the defendant knew the funds were derived from or intended to support illegal activity. That is where the knowledge element has real teeth.
Was It Really a “Business”?
Whether someone was operating a money transmitting “business” rather than doing personal financial activity is a fact-specific question. FinCEN’s regulations describe the inquiry as a totality-of-the-circumstances test. Prosecutors point to charging fees or commissions, handling third-party funds on a recurring basis, advertising exchange services, and processing high transaction volume. A single Bitcoin trade with a friend probably isn’t a business. Dozens of transactions a month through online forums, with a markup, almost certainly is.
Who Counts as a Money Transmitter
Federal regulations define money transmission as accepting funds from one person and sending them to another person or location by any means.3eCFR. 31 CFR 1010.100 – General Definitions That definition is intentionally sweeping. It reaches wire transfer companies, check cashers, and currency dealers, but it also reaches operations that many operators don’t recognize as money transmission at all.
Hawalas and Informal Value Transfer
The regulatory definition explicitly includes informal value transfer systems such as hawalas. These networks move value internationally through brokers who settle debts among themselves rather than moving currency across borders. Because hawala operators accept value from customers and arrange for delivery elsewhere, they meet the definition and must register with FinCEN. Prosecutors have brought § 1960 charges against hawala operators who skipped registration, especially in cases connected to terrorism financing or sanctions evasion.
Cryptocurrency Exchangers
FinCEN treats virtual currency exchangers and administrators as money transmitters. Under its 2013 guidance, a person who accepts and transmits convertible virtual currency, or buys and sells it as a business, qualifies as a money transmitter unless a specific exemption applies.4FinCEN.gov. Application of FinCENs Regulations to Persons Administering, Exchanging, or Using Virtual Currencies Using virtual currency to buy goods for yourself is not money transmission. Exchanging it for others as a business is.5Financial Crimes Enforcement Network. Advisory on Illicit Activity Involving Convertible Virtual Currency
The rule applies to peer-to-peer traders. Sal Mansy, a Michigan man who ran a Bitcoin exchange through his company, was sentenced to a year and a day in federal prison for operating without FinCEN registration.6United States Department of Justice. Detroit Man Sentenced to a Year and a Day for Operating an Unlicensed Bitcoin Business Larry Dean Harmon, who ran the Helix darknet cryptocurrency mixer, received a three-year sentence and a $60 million FinCEN civil penalty for laundering more than $300 million in Bitcoin.7United States Department of Justice. Operator of Helix Darknet Cryptocurrency Mixer Sentenced in Money Laundering Conspiracy Michael Lord, who operated another unlicensed Bitcoin exchange, received a 46-month sentence after pleading guilty to conspiracy.8Justia. USA v. Michael Lord
Decentralized Applications
FinCEN’s 2019 guidance extended the framework to decentralized applications. When a DApp accepts and transmits value, its owners or operators can be classified as money transmitters subject to Bank Secrecy Act registration, regardless of whether the DApp runs on a decentralized blockchain or without a traditional corporate structure.9Financial Crimes Enforcement Network. Application of FinCENs Regulations to Certain Business Models Involving Convertible Virtual Currencies FinCEN’s position is that decentralization does not create an exemption.
Certain entities are excluded from money transmitter status by regulation, including banks, some payment processors working through BSA-regulated intermediaries, clearance and settlement systems between regulated institutions, and armored car services that only transport currency for financial institutions.3eCFR. 31 CFR 1010.100 – General Definitions Whether a given operation qualifies is fact-specific, and getting the analysis wrong can be the difference between a compliant business and a felony charge.
Penalties on Conviction
A conviction under § 1960 is a felony carrying up to five years in prison per count.1Office of the Law Revision Counsel. 18 U.S. Code 1960 – Prohibition of Unlicensed Money Transmitting Businesses Defendants facing multiple counts for separate transactions or time periods can receive consecutive sentences. Judges weigh the total dollar volume transmitted, the length of the operation, and whether the business facilitated other crimes such as drug trafficking or fraud.
Fines follow the general federal fine statute. Individuals face up to $250,000 per count; organizations face up to $500,000. If the offense produced a gain to the defendant or a loss to a victim exceeding those amounts, the fine can be doubled to match.10Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
Mandatory Forfeiture
Under 18 U.S.C. § 982(a)(1), a court sentencing someone convicted under § 1960 must order forfeiture of any property involved in the offense or traceable to it.11Office of the Law Revision Counsel. 18 USC 982 – Criminal Forfeiture The language is mandatory. Bank accounts used to process transactions, real estate purchased with proceeds, vehicles, and equipment are all reachable. In the Harmon case, the government pursued forfeiture of cryptocurrency worth hundreds of millions of dollars alongside the prison sentence.7United States Department of Justice. Operator of Helix Darknet Cryptocurrency Mixer Sentenced in Money Laundering Conspiracy
Parallel Civil Penalties
Criminal prosecution is not the only exposure. FinCEN can impose civil money penalties on its own. Under 31 U.S.C. § 5330, failing to comply with registration requirements triggers a civil penalty of $5,000 for each violation, with each day of continued noncompliance counted as a separate violation.12Office of the Law Revision Counsel. 31 U.S. Code 5330 – Registration of Money Transmitting Businesses A business unregistered for a year could face more than $1.8 million in civil penalties before any indictment.
FinCEN can also assess civil penalties for other BSA violations, such as failing to maintain an anti-money laundering program or neglecting to file suspicious activity reports.13Financial Crimes Enforcement Network. Enforcement Actions for Failure to Register as a Money Services Business Harmon’s case shows how the two tracks run in parallel: the DOJ prosecuted him criminally while FinCEN separately assessed a $60 million civil money penalty for BSA violations tied to his mixer.14Financial Crimes Enforcement Network.

Defenses That Have Traction
Defendants face an uphill fight given the statute’s breadth and its relaxed knowledge requirement. A few defenses still do real work.
Lack of Knowledge of Factual Elements
Ignorance of licensing law is not a defense, but ignorance of relevant facts can be. A defendant who genuinely believed transactions stayed within a single state can challenge the interstate commerce element. A defendant charged under the criminal-funds prong can argue there was no reason to know the money was tied to illegal activity. Courts distinguish willful blindness, which can substitute for actual knowledge, from genuine ignorance of facts the defendant had no reason to discover.
Not Operating a “Business”
If the conduct was isolated and personal rather than a business, the statute doesn’t apply. Defendants who exchanged currency on a small number of occasions without advertising, charging fees, or soliciting customers have the strongest version of this argument.
Fourth Amendment Suppression
When evidence came from warrantless searches or seizures, defense counsel can move to suppress. Financial records seized without a proper warrant, unauthorized surveillance, and constitutionally defective undercover operations are all vulnerable. If the suppressed evidence was central to the case, the charges may not survive.
Vagueness as Applied
Defendants sometimes argue that § 1960 is unconstitutionally vague as applied to their conduct, especially in novel contexts involving new technology or unusual business models. Courts have generally found the statute clear enough to put operators on notice, so the defense has had limited success, but it can force scrutiny of whether the government is stretching the statute past its intended reach.
