Form 8300: Report of Cash Payments Over $10,000 Received in a Trade or Business
Required when a business receives more than $10,000 in cash in a single transaction or in related transactions, to help detect money laundering and tax evasion.
Overview
Form 8300 is an IRS information return that any person engaged in a trade or business must file when they receive more than $10,000 in cash in a single transaction or in two or more related transactions. The form serves a dual purpose: it is filed with the IRS and simultaneously satisfies the Financial Crimes Enforcement Network (FinCEN) reporting requirement under 31 U.S.C. § 5331, which is the Bank Secrecy Act's cash-reporting mandate for non-financial businesses. The underlying policy goal is to create a paper trail that helps federal authorities detect money laundering, drug trafficking proceeds, and large-scale tax evasion.
The $10,000 threshold applies to cash in its broadest sense. "Cash" under Form 8300 rules means U.S. currency, foreign currency, and certain monetary instruments — cashier's checks, bank drafts, traveler's checks, and money orders — when their face value is $10,000 or less and they are received in a designated reporting transaction. Personal checks, business checks, and wire transfers do not count as cash for Form 8300 purposes, though businesses should be aware that structuring transactions to avoid the threshold is itself a federal crime.
Unlike most IRS forms that follow an annual filing cycle, Form 8300 is transaction-driven. The filing deadline is 15 calendar days after the date the cash is received. Businesses must also provide a written statement to each payer identified on the form by January 31 of the following year. Covered businesses span a wide range of industries — auto dealers, jewelry stores, attorneys, real estate professionals, pawn shops, and many others — making this one of the more broadly applicable compliance obligations outside traditional payroll and income reporting.
Who Files This Form?
Any person in a trade or business who receives more than $10,000 in cash in a single transaction must file Form 8300. The obligation also applies when a series of related transactions cumulatively exceeds $10,000 in cash, even if no individual payment crosses the threshold. The IRS uses the phrase "related transactions" to capture installment payments for a single purchase, multiple payments by the same buyer within 24 hours, or payments that a business knows (or has reason to know) are connected.
The filer can be a sole proprietor, partnership, corporation, or any other business entity — the form is not limited to financial institutions. Common industries with frequent Form 8300 obligations include automobile and boat dealers, real estate closing agents, attorneys receiving client retainers, coin and precious-metals dealers, pawn shops, travel agencies, and businesses that sell high-value consumer goods.
Important exceptions and edge cases: (1) Transactions in which the buyer uses a personal or business check do not trigger the form, regardless of amount. Wire transfers and ACH payments are similarly excluded. (2) Businesses that receive cashier's checks, money orders, or traveler's checks with a face value exceeding $10,000 each are generally not required to treat those instruments as cash — but if those instruments are used in a designated reporting transaction (e.g., purchasing a vehicle), special rules apply and a CPA should confirm whether the transaction qualifies. (3) The obligation runs to the person who receives the cash, not the buyer. If an agent receives cash on behalf of a principal, the agent files. (4) Tax-exempt organizations are not exempt from Form 8300 if they are conducting a trade or business. (5) Suspicious transactions that do not meet the $10,000 threshold may still be reported voluntarily, and the IRS encourages this practice when structuring is suspected.
Key Fields
Part I — Identity of Individual from Whom Cash Was Received (Lines 1–13)
This section captures the payer's full legal name, address, date of birth, taxpayer identification number (SSN or ITIN), and occupation. If the person providing the cash is acting on behalf of another party, both identities must be reported. A common mistake is leaving the TIN blank when the payer refuses to provide it — in that case, the business must still file, note the refusal, and document its good-faith effort to obtain the number.
Part II — Person on Whose Behalf Transaction Was Conducted (Lines 14–22)
If the transaction is conducted on behalf of someone other than the individual in Part I — for example, a buyer's agent paying on behalf of a corporate entity — this section captures that beneficial owner's identity. Many businesses overlook this section when an employee or third-party intermediary hands over the cash, which can render the form incomplete.
Box 23 — Date Cash Received
Enter the actual calendar date on which the cash (or the final installment that pushed the cumulative total over $10,000) was received. This date drives the 15-day filing deadline, so accuracy here is critical. For multi-payment transactions, this is the date the aggregate threshold was crossed, not the date of the first payment.
Box 24 — Total Cash Received
Report the total dollar amount of cash received in the transaction or related transactions. Do not net out any fees, commissions, or costs. The gross amount of cash received is what belongs here. Over-reducing this figure is one of the more common errors on the form.
Box 25 — If Cash Was Received in More Than One Payment, Check Here
This checkbox signals to the IRS that the filing covers multiple related payments rather than a single lump-sum receipt. Checking this box triggers the expectation that the total in Box 24 represents an aggregate. Failing to check it when installments are involved can appear to misrepresent the nature of the transaction.
Box 26 — Total Price If Different from Amount in Box 24
If the total purchase price exceeds the cash received (e.g., the buyer paid partly in cash and partly by check), enter the full contract price here. This allows the IRS to see the full transaction context, even though only the cash portion drives the reporting obligation.
Box 27 — Amount of Cash Received in U.S. Dollar Bills and/or Coins
Break out the portion of cash that consists of physical U.S. currency. If the payment also included foreign currency or qualifying monetary instruments, those are reported separately in subsequent boxes. Disaggregating currency types helps law enforcement identify payment patterns.
Box 28 — Type and Amount of Foreign Currency (if applicable)
Report any foreign currency received and its U.S. dollar equivalent at the exchange rate on the date received. Use a reputable published exchange rate (e.g., Federal Reserve noon rate or a major commercial bank rate) and document which rate you used. Guessing or rounding materially can create discrepancies if the transaction is ever reviewed.
Part IV — Business That Received Cash (Lines 33–38)
This section identifies the filer — the business's legal name, EIN, address, and the nature of its business (e.g., auto dealer, jeweler, attorney). The "nature of transaction" description in Line 38 should be specific: "sale of 2025 pickup truck, VIN XXXXX" is better than "vehicle sale." Vague descriptions are one of the red flags IRS examiners look for.
Signature and Date (Bottom of Form)
The form must be signed under penalties of perjury by an authorized officer or employee of the business. Electronic filing through FinCEN's BSA E-Filing System uses a PIN-based signature. An unsigned or improperly signed form is treated as not filed, which can trigger penalties.
Filing Deadlines
15 days after the transaction
$25,000 fine or 5 years imprisonment for willful failure to file; civil penalties of $280 per failure (up to $3.4 million per year).
Step-by-Step Instructions
- 1
Identify the triggering event: On the date a single cash transaction exceeds $10,000, or on the date cumulative related-transaction cash receipts cross $10,000, flag the transaction for Form 8300 reporting. Set a calendar reminder for the filing deadline, which is 15 calendar days after the triggering date.
- 2
Collect payer identification before releasing goods or services: Request and document the payer's full legal name, current address, date of birth, and taxpayer identification number. Best practice is to photocopy or scan the payer's government-issued ID. If the payer refuses to provide a TIN, note the refusal in writing and proceed with filing — you are not required to withhold goods or services, but you must document the attempt.
- 3
Determine whether a beneficial owner must be identified: Ask whether the individual tendering the cash is acting on behalf of another person or entity. If so, collect the beneficial owner's identity information for Part II. This step is frequently skipped and is a primary driver of incomplete filings.
- 4
Complete Part I (payer identity) and Part II (beneficial owner, if applicable): Enter all identifying information exactly as it appears on the ID provided. Transcription errors on names and TINs are the most common clerical mistakes.
- 5
Complete Part III (transaction description): Enter the date of cash receipt, total cash amount, breakdown by currency type, and a specific description of the transaction. Be precise about what was sold or what service was rendered. If multiple payments are involved, check Box 25 and list each payment date and amount in the space provided or on an attachment.
- 6
Complete Part IV (business identity): Enter the business's legal name, EIN, address, and a clear description of the business type and the specific nature of the transaction.
- 7
File the form: Submit Form 8300 to the IRS by the 15-day deadline. Electronic filing via the FinCEN BSA E-Filing System (which simultaneously satisfies the FinCEN requirement) is strongly recommended and is mandatory for businesses required to file 10 or more Forms 8300 in a calendar year beginning in 2024. Paper forms are mailed to the IRS Detroit Computing Center.
- 8
Send the required payer statement: By January 31 of the year following the calendar year in which the transaction occurred, provide a written statement to each person named in Part I of any Form 8300 filed during that year. The statement must include the business name and address, the aggregate amount of reportable cash, and a notice that the information was reported to the IRS.
- 9
Retain records: Keep a copy of each Form 8300 and all supporting documentation (copies of ID, transaction records, written statements) for five years from the date of filing. IRS and FinCEN examiners may request records during an audit or BSA compliance review.
Common Mistakes to Avoid
Missing the 15-day filing deadline because the transaction was not flagged at the time of payment.
Implement a point-of-sale or intake protocol that prompts staff to flag any cash payment approaching or exceeding $10,000 immediately, rather than discovering it during month-end reconciliation.
Failing to aggregate related transactions, resulting in a missed filing obligation.
Track cumulative cash received from the same buyer within a 12-month period for ongoing or installment transactions; file as soon as the running total crosses $10,000 and update the tracking log.
Treating cashier's checks, money orders, or traveler's checks with face values above $10,000 as non-cash and not filing.
Review IRS guidance carefully — these instruments are treated as cash when received in certain designated reporting transactions (e.g., retail sales of consumer durables, collectibles, or travel). When in doubt, file.
Omitting Part II (beneficial owner information) when the payer is acting as an agent or intermediary.
Train client-facing staff to ask "Are you paying on behalf of yourself or another party?" at the time of every large cash transaction, and document the answer.
Providing a vague transaction description in Part III, such as "merchandise" or "services rendered."
Be specific: include the type of good or service, make/model/serial number if applicable, and the transaction date. Vague descriptions increase audit scrutiny and may indicate an incomplete filing.
Forgetting to send the annual payer statement by January 31.
Add the Form 8300 payer statement to the January compliance calendar alongside W-2 and 1099 mailings; a separate penalty applies for failure to furnish the required statement.
Frequently Asked Questions
For Form 8300 reporting, cash includes U.S. coins and currency, foreign currency, and certain monetary instruments — specifically cashier's checks, bank drafts, traveler's checks, and money orders with a face value of $10,000 or less when received in connection with a designated reporting transaction. Personal checks, business checks, wire transfers, and ACH payments are not treated as cash under these rules, regardless of the dollar amount.
