Money Laundering and the Tax Code: Form 8300, FBAR, Penalties

Money laundering rules in the tax code and Bank Secrecy Act require reporting on three fronts: cash payments over $10,000 received in a trade or business, foreign financial accounts and assets, and digital asset transactions on your income tax return. Penalties for getting it wrong scale from civil fines in the tens of thousands of dollars to twenty years in federal prison, depending on whether the failure was negligent, willful, or part of an actual laundering scheme.

Cash Payments Over $10,000: Form 8300

Any business that receives more than $10,000 in cash from a single transaction, or from two or more related transactions, must report the payment to the IRS on Form 8300.¹ The filing deadline is 15 days after receiving the payment.² Businesses filing ten or more information returns in a year must submit Form 8300 electronically through FinCEN’s BSA E-Filing System.³

What Counts as Cash

Cash includes U.S. and foreign currency. It also includes cashier’s checks, bank drafts, traveler’s checks, and money orders with a face value of $10,000 or less, but only when received in a “designated reporting transaction”: the retail sale of a consumer durable such as a car worth more than $10,000, a collectible, or a travel or entertainment package.⁴ Those same instruments count as cash in any transaction where the recipient knows the buyer is using them to dodge the reporting rules. Personal checks drawn on an individual’s own bank account never count as cash, no matter the amount.¹

When Smaller Payments Add Up

The threshold is not just about a single large payment. Payments made by the same buyer within a 24-hour period are automatically treated as related. Beyond that window, installment payments crossing $10,000 within 12 months of the initial payment trigger a filing, as does any series of payments from the same buyer that pushes past $10,000 within 12 months.⁵ The IRS example: a travel agent receives $8,000 in cash from a client, then another $3,000 two days later for the same trip. Related transactions. File the form.

Customer Notification and Records

Filing the form creates two follow-on obligations. Every person named on Form 8300 must receive a written statement from the business confirming the report was filed with the IRS. That statement has to include the business name and address, a contact person’s phone number, and the total reportable cash amount, and it must go out by January 31 of the year after the payment was received.⁵ The business must also keep a copy of each Form 8300, supporting documentation, and the customer notification for five years from the filing date.⁶

Digital Assets: On Hold for Form 8300

Congress amended Section 6050I in 2021 to bring digital assets like cryptocurrency inside the definition of cash. The IRS has paused enforcement of that expansion until the Treasury Department publishes final regulations, so businesses do not currently need to count digital assets toward the $10,000 Form 8300 threshold.⁷ Traditional cash reporting rules remain in full effect.

Digital Assets on Your Tax Return

The Form 8300 pause does not affect income tax reporting. The IRS treats digital assets as property, meaning every sale or exchange is a taxable event that produces a capital gain or loss.⁸ Every Form 1040 asks a yes-or-no question about whether the taxpayer received, sold, exchanged, or otherwise disposed of any digital asset during the year, and the same question appears on partnership, corporate, trust, and gift tax returns. Checking “no” when the answer is “yes” is a false statement on a federal tax return, which turns a reporting problem into potential fraud. Even transactions that produce no gain or loss must be disclosed.

Accurate reporting requires records showing the date of each transaction, the number of units, the fair market value in U.S. dollars at the time, and your cost basis.

Foreign Accounts and Assets

Two separate regimes cover money held abroad, and many taxpayers have to file both.

FBAR (FinCEN Form 114)

Any U.S. person with a financial interest in, or signature authority over, foreign financial accounts must file an FBAR if the combined value of those accounts exceeds $10,000 at any point during the calendar year.⁹ The threshold applies to the aggregate of all foreign accounts, not each account individually. Five accounts holding $2,500 each still require a filing.

The civil penalty for a non-willful FBAR violation is up to $10,000 per account per year. For willful violations, the penalty jumps to the greater of $100,000 or 50 percent of the highest account balance during the year of the violation.¹⁰ No penalty applies to a non-willful violation if the taxpayer had reasonable cause and properly reported all income from the accounts. Criminal penalties for willful failure to file can reach five years in prison.

FATCA (Form 8938)

The Foreign Account Tax Compliance Act requires a separate disclosure of specified foreign financial assets on Form 8938, attached to your tax return. Thresholds depend on filing status and where you live:¹¹

Single filers in the U.S.: foreign assets over $50,000 on the last day of the year or $75,000 at any point during the year.
Married filing jointly in the U.S.: over $100,000 at year-end or $150,000 at any point during the year.
Single filers abroad: over $200,000 at year-end or $300,000 at any point during the year.
Married filing jointly abroad: over $400,000 at year-end or $600,000 at any point during the year.

Form 8938 sweeps in more than bank accounts, including foreign stock, securities, and interests in foreign entities.

Conduct That Crosses into Money Laundering

Structuring

Structuring means breaking a large cash amount into smaller transactions to keep any single one below the $10,000 reporting threshold. Someone depositing $25,000 in cash as three separate $8,000 deposits at different branches is structuring, and it is illegal under the Bank Secrecy Act whether or not the money itself was legally earned.¹² The government does not need to prove the underlying funds came from crime. Evading the report is the crime.

Shell Companies and Real Estate

Shell companies with no real operations are used to route funds through multiple accounts so the original source becomes hard to trace, letting illicit money appear on a tax return as ordinary business income. Real estate is a common vehicle because property deals routinely move hundreds of thousands or millions of dollars without raising suspicion, and all-cash purchases through shell entities can hide the buyer’s identity behind the LLC on the deed.

Penalties

Form 8300 Failures

Civil penalties for failing to file Form 8300, or filing with incorrect information, escalate based on how late the filing is and whether the failure was intentional. For intentional disregard of the requirement, the penalty is the greater of $25,000 per return or the amount of cash involved in the transaction, capped at $100,000 per return.⁵ The penalty tracks the cash you failed to report, not a flat fee.

Structuring

Structuring carries a criminal penalty of up to five years in prison plus fines under Title 18. If the structuring happened alongside another federal crime or was part of a pattern involving more than $100,000 in a 12-month period, the maximum doubles to ten years.¹³

Money Laundering Itself

The heaviest penalties apply to laundering. Under the primary federal money laundering statute, a conviction carries up to 20 years in prison and a fine of up to $500,000 or twice the value of the property involved, whichever is greater.¹⁴ A related statute covering monetary transactions in criminally derived property carries up to ten years.¹⁵ The government can also pursue civil penalties of up to the value of the property involved or $10,000, whichever is greater, even without a criminal conviction. Conspiracy to launder carries the same penalties as the underlying offense, so agreeing to a scheme exposes you to the full 20-year maximum even if the laundering never goes through.

Correcting a Past Failure

Taxpayers who realize they missed a required report have limited routes to come forward before the IRS finds them first. Which route works depends on whether the failure was intentional.

Streamlined Filing Compliance Procedures

If your failure to report foreign financial assets or file FBARs was due to negligence, a good-faith misunderstanding, or an honest mistake, you may qualify for the streamlined filing compliance procedures. You must certify under penalty of perjury that the failure was non-willful.¹⁶ Eligibility ends the moment the IRS opens a civil examination of any of your returns or begins a criminal investigation, whether or not either action relates to foreign assets.

Voluntary Disclosure Practice

For taxpayers who willfully failed to comply or committed tax crimes, IRS Criminal Investigation runs a separate Voluntary Disclosure Practice. A valid disclosure must be truthful, timely, and complete. Timely means the IRS has not already opened an examination, received a tip from a third party, or obtained information about your noncompliance through a criminal enforcement action such as a search warrant or grand jury subpoena.¹⁷

The practice is not open to taxpayers with income from illegal sources, including sources legal under state law but illegal under federal law. Participation requires a two-part electronic application on Form 14457: the first part establishes eligibility, and the second must be submitted within 45 days of receiving a preclearance letter. The taxpayer must cooperate fully and pay all back taxes, interest, and penalties, or secure a full-pay installment agreement.¹⁷ Coming forward does not guarantee immunity from prosecution, but the IRS has historically declined to refer voluntary disclosure cases for criminal charges when taxpayers fully cooperate.
