The Money Laundering Control Act of 1986 made money laundering a federal crime in the United States. Signed into law as part of the Anti-Drug Abuse Act of 1986 (Public Law 99-570), it was the first federal statute to treat the act of disguising criminal proceeds as a prosecutable offense on its own, separate from the underlying crime that generated the money. The United States became the first country in the world to criminalize money laundering as a standalone offense.
What Changed in 1986
Before the 1986 Act, no federal law directly prohibited laundering money. Prosecutors could charge people under the Bank Secrecy Act of 1970 for failing to file required reports on large cash transactions, but the actual movement and concealment of criminal proceeds was not itself a crime.1Office of the Law Revision Counsel. 31 USC 5311 – Declaration of Purpose A drug trafficker could be prosecuted for selling drugs, but the accountant, lawyer, or business owner helping move the profits through the financial system faced no federal charge aimed at that specific conduct.
Congress passed the Act largely in response to drug trafficking and organized crime. Lawmakers recognized that seizing drug shipments alone would not dismantle organizations whose profits remained intact. The new law gave prosecutors an independent charge aimed at anyone who helped funnel, hide, or spend criminal proceeds through the financial system, whether or not that person had participated in the predicate crime.2Legal Information Institute (LII).

The Two Statutes the Act Created
The 1986 Act added two sections to Title 18 of the United States Code. Both remain the backbone of federal money laundering prosecutions today.
18 U.S.C. 1956
Section 1956 is the broader and more heavily penalized offense. It applies when a person conducts or attempts to conduct a financial transaction knowing the funds represent proceeds of illegal activity, with the intent to promote further criminal activity or to conceal the nature, source, ownership, or control of the proceeds. The statute also reaches the transportation of funds or monetary instruments across international borders with similar intent.3Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments
Section 1956 also contains a sting provision. A person can be convicted even when the funds are not actually criminal proceeds, as long as the money was represented to be proceeds of illegal activity (typically by an undercover officer) and the defendant acted with the required intent. The statute reaches conduct outside the United States when it involves a U.S. citizen or occurs partly within the country, provided the transaction exceeds $10,000.4Office of the Law Revision Counsel. 18 U.S. Code 1956 – Laundering of Monetary Instruments
18 U.S.C. 1957
Section 1957 targets a narrower but easier-to-prove offense: knowingly engaging in a monetary transaction worth more than $10,000 using property derived from a specified unlawful activity. Unlike Section 1956, the government does not need to prove the defendant intended to conceal anything or promote further crime, nor that they knew which specific crime generated the funds.5Office of the Law Revision Counsel. 18 USC 1957 – Engaging in Monetary Transactions in Property Derived From Specified Unlawful Activity Simply using the money in a transaction over the threshold, with knowledge that it came from criminal activity, is enough.
What Counts as the Underlying Crime
Both statutes require the funds to come from a “specified unlawful activity.” The term is defined broadly in Section 1956(c)(7) and covers dozens of federal and foreign offenses, not only drug crimes. The list includes:
- Racketeering offenses under the federal RICO statute, including extortion, gambling, loan sharking, and bribery
- Drug trafficking
- Bank fraud, wire fraud, mail fraud, securities fraud, and health care fraud
- Violent crimes committed against a foreign nation, such as murder, kidnapping, and robbery
- Bribery of a public official and embezzlement of public funds
- Human trafficking and sexual exploitation of children
- Providing material support to terrorist organizations
- Illegal trafficking in weapons or controlled technology
Because the list is so extensive, nearly any significant federal crime that generates money can serve as the predicate for a laundering charge.4Office of the Law Revision Counsel. 18 U.S. Code 1956 – Laundering of Monetary Instruments
Penalties Under the Act
A conviction under Section 1956 carries up to 20 years in prison per count and a fine of up to $500,000 or twice the value of the property involved, whichever is greater.3Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments A conviction under Section 1957 carries up to 10 years in prison per count and a fine of up to twice the amount of the criminally derived property involved in the transaction.5Office of the Law Revision Counsel. 18 USC 1957 – Engaging in Monetary Transactions in Property Derived From Specified Unlawful Activity Conspiring to commit either offense carries the same penalties as the completed crime.
Forfeiture is not optional. Upon conviction under Section 1956 or 1957, the court must order the defendant to forfeit any real or personal property involved in the offense or traceable to the laundered funds. Homes, vehicles, bank accounts, and investment holdings are all subject to seizure.6Office of the Law Revision Counsel. 18 USC 982 – Criminal Forfeiture The government may also pursue civil forfeiture of property linked to money laundering without a criminal conviction of the owner.7Office of the Law Revision Counsel. 18 USC 981 – Civil Forfeiture
The default statute of limitations is five years. Section 1956 extends that window to seven years when the predicate offense is a foreign crime such as drug trafficking, foreign bank fraud, bribery of foreign officials, or human trafficking.4Office of the Law Revision Counsel. 18 U.S. Code 1956 – Laundering of Monetary Instruments
How Later Laws Built on the 1986 Act
The 1986 Act did not stand alone for long. Congress has expanded the federal anti-money-laundering framework several times, but the two criminal statutes it created remain the core.
The Bank Secrecy Act of 1970, which predates the 1986 Act, continues to require financial institutions to file Currency Transaction Reports for cash transactions over $10,000 and Suspicious Activity Reports for transactions that may involve illegal activity.8Office of the Law Revision Counsel. 31 U.S. Code 5318 – Compliance, Exemptions, and Summons Authority After 1986, these reports became evidence not only of reporting violations but of the underlying laundering offense itself.
Title III of the USA PATRIOT Act, formally the International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001, extended the framework to terrorism financing, imposed customer identification requirements on financial institutions, tightened rules for correspondent banking with foreign banks, and broadened the definition of “financial institution” to cover money transmitters and other previously unregulated entities.9Financial Crimes Enforcement Network. USA PATRIOT Act
The Anti-Money Laundering Act of 2020, enacted on January 1, 2021, is the most recent major update. Among other changes, it created a whistleblower program paying mandatory awards of up to 30 percent of monetary sanctions collected to individuals who provide original information leading to successful enforcement actions over $1 million.10Office of the Law Revision Counsel. 31 USC 5323 – Whistleblower Incentives and Protections
Each of these laws added tools, reporting duties, and jurisdictional reach. None replaced the 1986 Act. When federal prosecutors charge someone with money laundering today, the charge still rests on Section 1956 or Section 1957, the two offenses Congress created nearly four decades ago.
