Structuring is the deliberate breaking up of cash transactions to keep each one below the $10,000 federal reporting threshold. So what is structuring in legal terms? It’s a federal felony under the Bank Secrecy Act, punishable by up to five years in prison, and the crime is the act of dodging the report itself. It does not matter whether the underlying money was earned honestly. A restaurant owner splitting a week’s legitimate cash receipts into $9,000 deposits commits the same offense as someone laundering drug proceeds.
The $10,000 Reporting Rule Behind the Crime
Every bank, credit union, and similar financial institution in the United States has to file a Currency Transaction Report, or CTR, whenever it handles a cash transaction of more than $10,000 in a single business day.1Financial Crimes Enforcement Network. Suspicious Activity Reporting (Structuring) The requirement comes from 31 U.S.C. § 5313, and the reports go to the Financial Crimes Enforcement Network (FinCEN), a Treasury bureau that keeps a database of large cash movements for law enforcement.2Office of the Law Revision Counsel. 31 USC 5313 – Reports on Domestic Coins and Currency Transactions
The threshold isn’t per visit. Federal regulations require banks to add up multiple cash transactions by or on behalf of the same person during a single business day, and if the total exceeds $10,000, the bank must file as if it were one transaction.3eCFR. 31 CFR 1010.313 – Aggregation Deposits left overnight or on a weekend count as received on the next business day.
Structuring exists as a crime because the reporting rule only works if people can’t route around it. Congress made evasion itself the offense under 31 U.S.C. § 5324: no person may structure or assist in structuring any transaction with a financial institution for the purpose of evading the reporting requirements.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
What Structuring Looks Like
The classic pattern is a series of cash deposits sized to sit just under $10,000. Several deposits of $9,000 or $9,500 within a short window. Two visits to different branches of the same bank on the same day. Splitting a single sum across separate banks. Buying multiple cashier’s checks or money orders just below the threshold. The statute reaches all of it, and using more than one financial institution offers no cover because § 5324 covers transactions with “one or more domestic financial institutions.”4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
Individual deposits that look ordinary in isolation can become powerful evidence when investigators line them up. Federal agencies stitch transactions together across institutions using the identifying data banks collect, so the illusion of separateness rarely survives scrutiny.
Intent Is What Turns Small Deposits Into a Crime
Structuring is not a strict-liability offense. The government has to prove the person acted with the specific purpose of evading the reporting requirement. Making multiple small deposits, by itself, is not illegal. A food truck operator who deposits a few thousand dollars every Friday after a week of sales isn’t structuring. The crime requires a conscious decision to keep transactions below $10,000 because of the reporting threshold.
Prosecutors usually build intent from circumstantial evidence: the timing and size of deposits, sudden shifts in banking behavior, and how tightly the amounts cluster to $10,000. Three deposits of $9,900 in a single week tells a very different story than steady $2,000 deposits over months. The government doesn’t have to show the person knew the statute number or even that structuring is itself a crime. It only has to show the person knew banks report large cash transactions and tried to avoid triggering a report.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
This is where most structuring cases turn. Bank tellers occasionally mention the $10,000 rule to customers in passing. A customer who then starts depositing $9,500 has essentially handed prosecutors their intent evidence. If a bank employee mentions the threshold and you change your deposit behavior afterward, the sequence itself is close to conclusive.
Prison Time and Fines
A federal structuring conviction carries up to five years in prison and substantial fines. Penalties climb sharply when structuring accompanies another federal crime or is part of a pattern of illegal activity involving more than $100,000 in a 12-month period. In those aggravated cases the maximum prison term doubles to ten years and the available fines increase.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
Structuring rarely travels alone in a charging document. It often appears next to tax evasion or money laundering counts, each carrying its own prison exposure. Even standing on its own, without any other underlying offense, structuring is a felony that leaves a permanent criminal record.
Losing the Money Through Forfeiture
Prison is only part of what’s at stake. Under 31 U.S.C. § 5317, the government can seize any property involved in a structuring violation, and any property traceable to it, through either criminal or civil forfeiture.5Office of the Law Revision Counsel. 31 USC 5317 – Search and Forfeiture of Monetary Instruments Civil forfeiture is the more controversial route because the case is filed against the property itself, meaning money can be taken even when no one is charged with a crime.
That authority drew heavy criticism after the IRS seized accounts from convenience stores, restaurants, and other cash-heavy small businesses whose only apparent wrong was making frequent sub-$10,000 deposits. Congress responded by narrowing the IRS’s power: the agency may now seize property for a structuring violation only if the funds came from an illegal source or the structuring was designed to conceal a separate criminal violation beyond structuring itself.5Office of the Law Revision Counsel. 31 USC 5317 – Search and Forfeiture of Monetary Instruments
The Justice Department imposed its own restrictions in a 2015 policy directive. Federal prosecutors may not pursue seizure of structured funds unless there is probable cause the money came from unlawful activity or was intended to conceal ongoing criminal conduct. Where no such link exists, a seizure warrant requires personal, non-delegable approval from the U.S. Attorney or the Chief of the Asset Forfeiture and Money Laundering Section.6U.S. Department of Justice. Guidance Regarding the Use of Asset Forfeiture Authorities in Structuring Cases These reforms cut back on legal-source seizures without eliminating them.
Property owners can contest a forfeiture in court. Under the Civil Asset Forfeiture Reform Act, the government carries the burden of proving by a preponderance of the evidence that the property is subject to forfeiture, and it must show a substantial connection between the property and the offense if its theory is that the property facilitated a crime.7U.S. Department of Justice. Civil Asset Forfeiture Reform Act of 2000 An “innocent owner” defense is also available for people who didn’t know about the conduct behind the seizure, or who took reasonable steps to stop it once they learned.8Office of the Law Revision Counsel. 18 USC 983 – General Rules for Civil Forfeiture Proceedings Deadlines for filing a claim are short, so anyone whose account is seized should get counsel quickly.
It Isn’t Only About Banks
The $10,000 reporting duty extends beyond banks. Any trade or business that receives more than $10,000 in cash has to file IRS/FinCEN Form 8300 with the federal government.9Internal Revenue Service. IRS Form 8300 Reference Guide Car dealerships, jewelry stores, real estate agents, and attorneys taking large cash payments are all covered. And § 5324 separately makes it a crime to structure payments to non-financial businesses to evade that Form 8300 requirement.4Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
Payments count as related and must be combined when the same buyer makes payments totaling more than $10,000 within a rolling 24-hour period, and businesses that know or have reason to know that separate payments are part of a connected series must aggregate them even across longer spans.9Internal Revenue Service. IRS Form 8300 Reference Guide Splitting a purchase across two visits doesn’t dodge the reporting obligation, and doing so on purpose is the same federal offense with the same prison exposure as splitting a bank deposit.
How to Handle a Large Cash Transaction
The safest approach is the simplest one. Deposit or transact the full amount and let the bank file whatever reports it has to file. A CTR is not an accusation. It’s a routine filing that triggers no investigation on its own, and banks file millions each year that lead nowhere. The report becomes one record in a large federal database.
People get into trouble when they treat the CTR as something to be avoided. Splitting a $15,000 deposit across two visits doesn’t save paperwork. It creates evidence of a federal crime. If someone at the bank mentions the $10,000 threshold, don’t change your plans in response. Deposit the full amount. For a cash-heavy business making regular deposits that occasionally cross the line, the answer is consistency: steady banking patterns and clean records showing where the cash came from. Consistent behavior is itself evidence of innocence if questions ever arise.
