Structuring Bank Deposits, IRS Reporting Obligations, and Attorney Retainers

Depositing a large amount of cash is not a crime. Breaking that cash into smaller transactions to prevent the government from receiving a legally required report can be.

That distinction lies at the center of federal structuring investigations. Even lawfully earned money can create criminal exposure if transactions are arranged to evade reporting. The same concern arises when a business, or a law firm, receives cash in installments designed to remain below a reporting threshold.

Two reporting systems are frequently confused. Banks file Currency Transaction Reports for certain cash transactions. Trades and businesses, including law firms, file Form 8300 when they receive more than $10,000 in cash in a transaction or related transactions.

What Happens When More Than $10,000 in Cash Is Deposited?

Under the Bank Secrecy Act regulations, a financial institution generally must file a Currency Transaction Report, or CTR, for a deposit, withdrawal, exchange, or other transaction involving more than $10,000 in currency. The bank generally aggregates same-day cash transactions it knows are conducted by or for the same person.

The bank, not the customer, files the CTR. Triggering one is not unlawful. A CTR is an information report, not an accusation that the money is illegal.

The rule also applies to withdrawals. The danger begins when a person changes a transaction because of the reporting rule, for example, by visiting separate branches, using different accounts, or spreading cash activity across several days to prevent a CTR.

Banks also have separate Suspicious Activity Report obligations. A pattern of below-threshold cash transactions may attract more scrutiny than one transparent transaction above $10,000. Federal regulations require banks to report certain transactions of at least $5,000 when the bank knows, suspects, or has reason to suspect that the activity is designed to evade Bank Secrecy Act requirements. A bank generally may not tell the customer that it filed a Suspicious Activity Report.

What Is Illegal Structuring?

Federal law, 31 U.S.C. § 5324, prohibits structuring or attempting to structure transactions with one or more financial institutions for the purpose of evading a reporting or recordkeeping requirement. It also prohibits causing a bank to omit a required report or place a material omission or misstatement in one.

The government therefore must prove more than a series of cash deposits below $10,000. It must prove the purpose to evade reporting. The funds do not have to come from drug trafficking, fraud, or another underlying crime. Lawfully obtained money can become the subject of a structuring prosecution if the transactions were arranged to defeat the reporting system.

Intent is often proved circumstantially through repeated deposits just below $10,000, use of multiple branches or accounts, statements about avoiding reports, or behavior changes after a bank employee explains the threshold. No single fact automatically establishes guilt, but patterns can become powerful evidence.

A violation of § 5324 is punishable by up to five years in prison. The maximum increases to ten years when the violation occurs while another federal law is being violated or as part of a pattern of illegal activity involving more than $100,000 during a twelve-month period. The government may also pursue forfeiture of funds involved in or traceable to the offense.

Form 8300 Is a Different Reporting Requirement

Form 8300 applies to the recipient of cash rather than the bank customer making a deposit. Under 26 U.S.C. § 6050I and 31 U.S.C. § 5331, a person engaged in a trade or business generally must file Form 8300 after receiving more than $10,000 in cash in one transaction or two or more related transactions.

The filing is generally due within 15 days. The business must provide a written statement to each person named in a required form by January 31 of the following year and retain a copy for five years. Businesses required to file at least ten other information returns during the calendar year generally must file Forms 8300 electronically.

For this purpose, “cash” includes U.S. and foreign currency. It can also include cashier’s checks, bank drafts, traveler’s checks, and money orders with face amounts of $10,000 or less in designated reporting transactions or when the recipient knows that an instrument is being used to avoid reporting. A personal check drawn on the payer’s own account is not cash for Form 8300 purposes, regardless of its amount. Ordinary wires, ACH transfers, and credit-card payments are also generally outside Form 8300’s definition of cash.

Payments cannot be isolated when they concern the same transaction or a connected series. Transactions within 24 hours are treated as related; those over a longer period are related when the recipient knows or has reason to know they form a connected series.

The regulation gives a lawyer-specific example: a client pays $8,000 in cash for the first month and $4,000 for the second month of the same criminal case. The $12,000 concerns one transaction—the legal services in that case—and must be reported. An initial payment of $10,000 or less is generally aggregated with later related payments during the applicable twelve-month period, with filing due after the total exceeds $10,000.

Section 6050I separately prohibits arranging or assisting transactions for the purpose of evading Form 8300. Calling the payments separate “retainers,” using multiple offices, or issuing separate invoices does not control if the payments are connected in substance.

Reporting Does Not Determine Whether a Deposit Is Taxable Income

A CTR or Form 8300 is an information report. Neither determines whether the funds are taxable income.

Cash business revenue is generally income, but a genuine loan, transfer between a person’s own accounts, returned principal, or other nontaxable source does not become income merely because it was deposited. Attorney retainers add a timing question: funds held in trust and not yet earned may be treated differently from fees the lawyer has an unrestricted right to use.

The IRS may use bank-deposit analysis when reported income does not reconcile with account activity. Unexplained deposits can become evidence even when no deposit exceeded $10,000. Businesses should maintain contemporaneous records identifying the payer, source, purpose, invoice or matter, deposit, refund, and tax treatment.

Attorney Retainers: Trust Accounting, Form 8300, and Privilege

Law firms are trades or businesses for purposes of Form 8300. The fact that a payment is a criminal-defense retainer does not create a blanket exemption.

Depositing the Retainer in Trust Does Not Avoid Form 8300

Whether an advance fee must be placed in an IOLTA or another client trust account depends on the governing jurisdiction and the fee agreement. ABA Model Rule 1.15 generally requires advance legal fees and expenses to be placed in a client trust account and withdrawn only as earned or incurred, but state rules and recognized retainer types vary.

That ethical classification is distinct from cash reporting. The Form 8300 regulation expressly includes the establishment or maintenance of, or a contribution to, a trust or escrow arrangement within its definition of a transaction. A law firm that receives more than $10,000 in currency for a matter cannot avoid reporting simply because it places the cash in an IOLTA rather than its operating account.

The later movement of earned funds from trust to operating is distinct from the reportable receipt. Records should trace the original payment, Form 8300 analysis, trust deposit, and later transfers.

Client Identity and Fee Information Are Usually Not Privileged

Form 8300 requires identifying information about the person from whom the cash was received and, when applicable, the person on whose behalf the transaction was conducted. Lawyers sometimes object that disclosing a client’s identity or fee payment could aid a criminal investigation.

Courts have generally rejected a categorical privilege objection. In United States v. Ritchie, the Sixth Circuit stated that client identity and payment of fees are ordinarily not privileged and upheld enforcement of an IRS summons seeking information omitted from Forms 8300. Other federal decisions likewise hold that the possibility that fee information may incriminate a client does not, standing alone, justify noncompliance.

Exceptional privilege questions can arise under particular facts and circuit law. Counsel should obtain jurisdiction-specific advice and, if appropriate, seek judicial protection. Filing an incomplete form and merely asserting privilege can expose the firm to penalties.

The Ethics of Reporting Cash Retainers and Client Transactions

The lawyer’s ethical duties point in two directions: preserve client confidences, but do not violate federal law or help a client evade it.

ABA Model Rule 1.6 permits a lawyer to disclose information to the extent reasonably necessary to comply with other law or a court order. A required Form 8300 therefore ordinarily falls within the required-by-law framework. Sound practice is to explain the reporting obligation before accepting reportable cash, collect the required identifying information, disclose no more than the law requires, file on time, and provide the required year-end statement.

The analysis is different when reporting is voluntary. IRS instructions permit a business to file Form 8300 for a suspicious transaction below $10,000, but a voluntary report is not automatically authorized by the “comply with other law” exception. ABA Formal Opinion 463 cautions that lawyers are not general financial-system gatekeepers and that reporting suspicions about clients can conflict with confidentiality duties. Before making a voluntary suspicious-transaction report concerning a client or prospective client, counsel should analyze the controlling state rule, informed consent, and any other applicable disclosure exception. A law firm should not assume that it has the same SAR duties as its bank.

At the same time, Model Rule 1.2(d) prohibits a lawyer from counseling or assisting criminal or fraudulent conduct. A lawyer may explain the reporting rules and advise a client to comply. The lawyer may not recommend dividing a cash retainer into $9,000 payments to prevent Form 8300, route the payments through third parties, misidentify the payer, or alter billing records to make connected payments appear unrelated. If a client insists on using the lawyer’s services or accounts to facilitate structuring, the lawyer may need to decline or withdraw, subject to applicable court rules.

The cleanest policy is transparency: the engagement agreement should state that the firm will comply with all cash-reporting laws; personnel should aggregate related payments across lawyers and offices; cash receipts should require supervisory review; and the firm should never allow its trust account to function as a client’s private banking channel.

What to Do When Deposits or Cash Payments Are Under Investigation

Once a bank asks questions, restricts an account, or receives a subpoena, improvising explanations can make matters worse. Preserve records immediately. Do not move funds, create backdated documents, or ask others to characterize deposits without legal advice.

Counsel should reconstruct each transaction, determine what the person knew about reporting, separate cash from other payments, identify related transactions, review tax records, and assess possible structuring, Form 8300, tax, false-statement, money-laundering, and forfeiture exposure. A simple banking question may already be part of a broader federal investigation.

Conclusion

The $10,000 threshold is not a safe harbor and should never be treated as a target. A legitimate transaction above the threshold is lawful; arranging smaller transactions to prevent reporting may not be. Businesses and law firms must independently evaluate Form 8300 when they receive cash, and attorneys must reconcile those federal duties with trust-account and confidentiality rules.

If you have received a grand jury subpoena, been contacted by IRS Criminal Investigation or another federal agency, experienced a seizure or account restriction, or discovered a possible Form 8300 problem, contact Chapman Law before providing a statement or moving additional funds. Early involvement by experienced federal criminal defense counsel can preserve records, define the reporting issues, and prevent avoidable decisions from becoming evidence of intent.
