Form 8300 Checklist – 2018 Tax Year
Purpose
Trades and businesses must file Form 8300 when they receive cash payments exceeding $10,000 in a single transaction or in related transactions. Form 8300 helps federal authorities combat money laundering, tax evasion, and other criminal activities by creating an audit trail of large cash payments. For 2018, the term "cash" includes U.S. and foreign currency, as well as cashier's checks, money orders, bank drafts, and traveler’s checks with face values of $10,000 or less under specified conditions.
This reporting requirement applies to non-financial trades and businesses receiving cash in the ordinary course of their operations. Financial institutions file separate Currency Transaction Reports using FinCEN Form 104 and do not use Form 8300 for their reporting obligations.
Required Filing Steps
Confirm the Transaction Threshold and Tax Year
Confirm the transaction occurred during 2018 and the total cash received equals or exceeds $10,000. Use Form 8300 (Rev. December 2017) or the most current revision approved for 2018 tax year filings.
Collect and Record Payer Information
Obtain and record the payer's full legal name, address, and taxpayer identification number. For individual payers, you must also record the date of birth in MM/DD/YYYY format and the occupation. If the payer's taxpayer identification number remains unavailable after a reasonable effort, document the reason in the Part III comments section.
Verify Government-Issued Identification
Identify and describe the payer's valid government-issued photo identification, including the issuer and identification number. Record driver's license details, passport numbers, or other acceptable identification documents. For nonresident aliens or foreign persons, record alien identification details or foreign passport information where applicable.
Identify Third-Party or Beneficial Owners
Determine whether the payer conducted the transaction on behalf of another person or entity. When a third party exists, complete Part II with the third party's name, taxpayer identification number, address, occupation, and business name or doing-business-as name if applicable.
Report Payment Date and Amount
Report the exact date you received the cash payment using the month, day, and year format. Record the total amount in U.S.-dollar equivalent for all payments that form part of the reportable transaction. For installment payments within 12 months that aggregate over $10,000, file the form within 15 days after receiving the payment that causes the total to exceed the threshold.
Classify the Transaction Type
Classify the transaction type as personal property, real property, services, intangible property, debt payment, exchange, escrow, or other category. Provide specific transaction descriptions, including vehicle identification numbers, serial numbers, property addresses, or registration numbers as applicable to the transaction type.
Itemize the Cash Composition
Break down the total payment by component type.
- U.S. currency, noting separately if $100 bills or higher denominations were received.
- Foreign currency with the country of origin identified.
- Cashier's checks, money orders, bank drafts, and traveler’s checks.
Include the issuer name and serial numbers for all monetary instruments reported as cash.
Complete Business Information and Certification
Complete Part IV with your business name, employer identification number or social security number, complete business address, and nature of business activity. Sign and date the form under penalties of perjury as the authorized official for the business entity filing the report.
Filing Methods and Deadlines
File Form 8300 within 15 days after the date you received the cash payment or the date the total payments exceeded $10,000. For 2018, electronic filing through FinCEN's Bank Secrecy Act E-Filing System was available voluntarily.
Paper filing remained the standard method, with completed forms mailed to the IRS Detroit Computing Center at P.O. Box 32621, Detroit, MI 48232. The mandatory electronic filing requirement did not take effect until January 1, 2024, and applied only to businesses required to file at least 10 other information returns electronically.
Related Transactions and Payment Tracking
Transactions between the same payer and recipient that occur within 24 hours automatically qualify as related transactions. You must combine these transactions and file Form 8300 if the total exceeds $10,000. Transactions that occur more than 24 hours apart still qualify as related transactions when you know or have reason to know they form a series of connected payments.
When tracking installment payments, add the first payment to any later payments made within one year of the first payment. File Form 8300 within 15 days of receiving the payment that causes the combined total to exceed $10,000.
Definition of Cash for Form 8300
Cash includes all coins and currency of the United States and any foreign country. Cashier's checks, money orders, bank drafts, and traveler’s checks with face values of $10,000 or less count as cash in designated reporting transactions or when you know the payer attempts to avoid Form 8300 reporting. Designated reporting transactions include retail sales of consumer durables with sales prices exceeding $10,000, collectibles, and travel or entertainment packages exceeding $10,000.
Monetary instruments with face values exceeding $10,000 do not qualify as cash. Personal checks drawn on individual accounts never qualify as cash for Form 8300 purposes.
Suspicious Transactions
You may voluntarily report suspicious transactions by checking box 1b on Form 8300 even when the payment amount falls below $10,000. A transaction appears suspicious when a person attempts to prevent Form 8300 filing, attempts to cause you to file false or incomplete information, or shows signs of possible illegal activity.
Federal law prohibits you from informing the payer that you checked the suspicious transaction box. You may also report suspicious activity by calling the IRS Criminal Investigation Division Hotline at 800-800-2877 or the Financial Institutions Hotline at 866-556-3974 for suspected terrorist activity.
Customer Notification Requirements
You must provide a written statement to each person named on Form 8300 by January 31 of the year following the cash payment. This statement must include your business name, address, contact person, telephone number, the total amount of reportable cash received during the 12 months, and confirmation that you reported the information to the IRS.
Do not send this notification for voluntary Form 8300 filings involving suspicious transactions under $10,000. Maintain copies of all filed Forms 8300 and customer statements for at least five years from the filing date.
Penalties
Civil penalties for negligent failure to file or for filing incomplete or incorrect information range from $250 to $310 per return, depending on the calendar year, with annual caps between $1,500,000 and $3,000,000. Intentional disregard carries penalties equal to the greater of $25,000 or the transaction amount, up to $100,000 per failure, with no annual limit.
Criminal penalties for willfully failing to file or filing false information include fines up to $25,000 for individuals or $100,000 for corporations and imprisonment up to five years. Structuring transactions to avoid the $10,000 reporting threshold violates federal law under 31 U.S.C. § 5324 and carries separate criminal penalties.
