Money Laundering Charges: Statutes, Penalties, and Investigation

Money laundering charges are federal felonies that punish knowingly moving, spending, or disguising money that came from criminal activity. A single count under 18 U.S.C. § 1956 carries up to 20 years in prison and a fine of up to $500,000 or twice the value of the money involved, whichever is larger. A related statute, 18 U.S.C. § 1957, punishes spending more than $10,000 of criminally derived money through a bank, with a 10-year maximum. Prosecutors routinely charge both, stack counts, and pursue forfeiture of the property tied to the scheme.

The Two Statutes Prosecutors Use

Federal money laundering cases are built on two statutes that cover different conduct and demand different proof.

18 U.S.C. § 1956: Concealment and Promotion

Under § 1956, the government must prove three things. The money came from a “specified unlawful activity,” a long statutory list that includes drug trafficking, fraud, bribery, and dozens of other federal offenses. The defendant knew the funds were criminal proceeds. And the transaction was designed either to promote more criminal activity or to hide the origin, ownership, or control of the money.¹

The knowledge element is less protective than it sounds. You do not have to know which crime generated the money; knowing it came from some kind of felony is enough. Courts have also adopted a “willful blindness” doctrine, meaning deliberately avoiding the truth is treated as the legal equivalent of knowing. Someone who repeatedly accepts large cash deposits with implausible explanations and makes a point of not asking has not insulated themselves from the charge.

Sting operations are covered too. If an undercover agent represents that funds are criminal proceeds and you agree to launder them, you face the same 20-year maximum even though the money was never actually dirty.¹

18 U.S.C. § 1957: Spending More Than $10,000

Section 1957 is narrower in what it reaches and easier to prove. The crime is knowingly conducting a financial transaction of more than $10,000 in criminally derived property through a financial institution. Prosecutors do not have to show any intent to conceal or promote; the act of moving the money through a bank, knowing it was tainted, is the offense.²

As with § 1956, the knowledge requirement does not demand that you know which crime produced the money. If someone hands you $50,000 and you deposit it knowing only that it came from “something illegal,” that is enough.²

What a Conviction Costs

The penalty structure is designed to erase any financial benefit from the scheme and add serious prison time on top.

Prison and Fines

Each § 1956 count carries up to 20 years in federal prison and a fine of up to $500,000 or twice the value of the property involved, whichever is greater.¹ The “twice the value” multiplier is where the real financial exposure sits. A scheme that moved $5 million can draw a $10 million fine on top of the sentence. Each § 1957 count carries up to 10 years and a fine of up to twice the money involved in the transaction.² When multiple counts are proven, judges frequently stack the sentences.

Conspiracy Exposure

You do not have to personally move any money to be convicted. Under 18 U.S.C. § 1956(h), conspiring to launder funds carries the same penalties as the completed offense. Agreeing to help and taking any step toward that goal exposes you to the full 20-year maximum, even if no laundering ever actually occurs.¹

Forfeiture

The government uses forfeiture to strip defendants of the property tied to the crime. Federal law provides for criminal forfeiture, which follows a conviction and targets the defendant’s property, and civil forfeiture, which is brought against the property itself and requires no criminal conviction. In civil forfeiture the government need only show by a preponderance of the evidence that the property was linked to criminal activity.³ Real estate bought with laundered money, vehicles used to move cash, and bank accounts holding criminal proceeds can all be seized. Civil forfeiture can also reach property held by third parties who were never charged, if the property itself is tied to illegal activity.

Structuring Is a Separate Charge

Breaking a cash transaction into smaller pieces to stay under reporting thresholds is its own federal crime, even when the money is completely legal. Under 31 U.S.C. § 5324, deliberately splitting a $25,000 deposit into three smaller ones to avoid a bank report is “structuring.”⁴

This catches people who assume clean money gives them a clean record. Someone with $15,000 in legitimate cash who deposits it in two chunks to avoid the paperwork has committed a federal felony. The crime is the act of structuring to evade the report, not whether the underlying money is dirty. Penalties run up to 5 years in prison for amounts under $100,000 in a 12-month period, and up to 10 years when the amount tops $100,000 or the structuring is tied to another offense. The same statute reaches people who split cash across multiple travelers to dodge the border declaration threshold.

How These Cases Get Built

Most money laundering investigations start with records the financial system is required to generate. The Bank Secrecy Act, passed in 1970, authorized the Treasury Department to impose reporting and recordkeeping requirements on banks and other institutions, and the Financial Crimes Enforcement Network (FinCEN) administers them.⁵ Two kinds of reports produce most of the leads.

Banks must file a Currency Transaction Report for every cash transaction over $10,000 in a single business day. Multiple cash deposits by the same person at the same bank that together exceed $10,000 are treated as one transaction and reported.⁶ The CTR itself is not an accusation; it is data that flows to FinCEN, where analysts look for patterns across institutions and across time.

Suspicious Activity Reports work differently. A bank must file a SAR whenever a transaction involves at least $5,000 and the bank has reason to suspect the funds are tied to illegal activity, the transaction is structured to evade BSA requirements, or there is no apparent lawful purpose.⁷ Banks and their employees are shielded from civil liability for filing a SAR even when the suspicion turns out to be wrong. That safe harbor is deliberately broad so institutions report freely.

Non-bank businesses are part of the net too. Any trade or business that receives more than $10,000 in cash in a single transaction or series of related transactions must file IRS Form 8300 within 15 days, which pulls car dealers, jewelers, attorneys, and real estate agents into the reporting system.⁸ Anyone physically carrying more than $10,000 in currency or monetary instruments into or out of the United States must file FinCEN Form 105 with Customs and Border Protection, and deliberately smuggling bulk cash to avoid that filing carries up to 5 years in prison plus forfeiture of the entire amount.⁹

If You See Laundering at Work

The Anti-Money Laundering Act of 2020 created federal protections for people who report suspected laundering. Under 31 U.S.C. § 5323, an employer cannot fire, demote, suspend, blacklist, or otherwise retaliate against a whistleblower who provides information to FinCEN, the Attorney General, a federal regulatory agency, or a congressional committee.¹⁰ A whistleblower who suffers retaliation can seek reinstatement, double back pay, and compensation for litigation costs. The protections also cover people who report internally within their own company, not only those who go directly to the government.
