If you run a business and receive large cash payments, federal law requires you to report them. Form 8300 is the IRS and Financial Crimes Enforcement Network (FinCEN) tool designed to help combat money laundering, tax evasion, and terrorist financing. While the form may sound intimidating, understanding when and how to file it will keep your business compliant and out of trouble.

What the Form Is For

Form 8300 serves as the government's eyes on large cash transactions in the business world. If you operate a trade or business and receive more than $10,000 in cash—either in a single payment or through related payments—you're legally required to report it.

This applies to virtually any business: car dealerships, jewelry stores, real estate agencies, law firms, travel agencies, casinos (for non-gaming activities), and even bail bondsmen.

What Counts as “Cash”

The "cash" definition is broader than you might think. It includes:

• U.S. and foreign currency, coins
• Cashier's checks, money orders, bank drafts, and traveler’s checks with a face value of $10,000 or less (in designated transactions)

However:

• Personal checks, wire transfers, and cashier's checks over $10,000 don’t count as “cash” for Form 8300 purposes.

This reporting requirement helps federal authorities track suspicious financial activity. When businesses comply, they create an audit trail that law enforcement can use to investigate drug dealing, tax fraud, and other crimes.

When You’d Use It (Including Late and Amended Filings)

Standard Filing Timeline

You must file Form 8300 within 15 days after receiving the cash payment that triggers the threshold.
If day 15 falls on a weekend or federal holiday, file on the next business day.

Related Transactions

Payments are “related” if they’re:

• From the same payer (or their agent) within a 24-hour period, or
• Known to be part of a connected series of transactions.

Example:
If a customer pays you $8,000 in cash today and $3,000 two days later for the same purchase, you’ve received $11,000 in related transactions—report within 15 days of the second payment.

Multiple Payments

If installment payments eventually exceed $10,000 within a 12-month period, file within 15 days of the payment that pushed the total over the threshold.
File again if additional payments exceed another $10,000 within the next 12 months.

Late Returns

If you miss the deadline, you must still file—mark the form “LATE.”

• For electronic filing: write “LATE” in the comments section.
• For paper filing: write it at the center top of page 1.

Failure to file in the required manner (e.g., mailing when e-filing is required) is also considered late.

Amended Returns

If you discover errors after filing:

• Check box 1a (“Amends prior report”)
• Complete the entire form with corrected information
• Don’t attach the original—just submit the amended version

Voluntary Reporting

You can voluntarily file Form 8300 for suspicious transactions under $10,000.
In these cases, you’re not required to send the written statement to the customer.

Common Mistakes and How to Avoid Them

Mistake #1: Misunderstanding What Counts as “Cash”

Many think only currency counts. Remember—cashier’s checks, money orders, bank drafts, and traveler’s checks under $10,000 may count in certain transactions.

Fix: Review the “cash” definition before deciding if you must file.

Mistake #2: Failing to Aggregate Related Payments

Fix: Track all payments from the same customer for at least 12 months.

Mistake #3: Missing or Incorrect TINs

Fix: Request and verify TINs upfront. Note “customer refused” if applicable and document attempts.

Mistake #4: Paper Filing When E-Filing Is Required

Fix: If you file 10 or more information returns (excluding Forms 8300), you must e-file.

Mistake #5: Sending Statements for Suspicious Transactions

Fix: Never send customer statements for suspicious reports.

Mistake #6: Ignoring the 15-Day Deadline

Fix: Set calendar reminders for timely filing.

Mistake #7: Vague Occupation Descriptions

Fix: Be specific—e.g., “attorney,” “jewelry retailer,” etc.
