What the Form Is For

Form 8300 is a federal reporting requirement designed to help the government track large cash transactions and combat money laundering, tax evasion, drug trafficking, and terrorist financing. If you operate any trade or business—whether you're a car dealer, jeweler, real estate broker, attorney, pawnbroker, travel agent, or any other commercial enterprise—and you receive more than $10,000 in cash from a single buyer in one transaction or in related transactions, federal law requires you to report it to both the Internal Revenue Service (IRS) and the Financial Crimes Enforcement Network (FinCEN).

The term “cash” is broader than just paper currency and coins. It includes U.S. and foreign currency, plus cashier's checks, bank drafts, traveler's checks, and money orders with a face amount of $10,000 or less when received in certain types of transactions or when you know the customer is trying to avoid reporting. However, personal checks drawn on someone's personal bank account don't count as cash for this purpose, and monetary instruments over $10,000 generally aren't considered cash because the issuing bank already reports those purchases.

This reporting requirement applies regardless of whether the transaction seems legitimate. Your role is simply to report qualifying cash payments—law enforcement agencies use this information to investigate potential criminal activity. By complying with Form 8300 requirements, businesses provide authorities with an essential audit trail while protecting themselves from serious civil and criminal penalties.

When You’d Use It (Late Filing and Amended Returns)

Regular Filing Deadline

You must file Form 8300 within 15 days after receiving the cash payment that causes the total to exceed $10,000. If the 15th day falls on a Saturday, Sunday, or legal holiday, the deadline extends to the next business day. For example, if you receive $18,000 cash on January 6, you must file Form 8300 by January 21 (or the next business day if January 21 is a weekend or holiday).

Multiple Payments Scenario

If a customer makes installment payments, you must track the cumulative total over a 12-month period. When payments from the same buyer exceed $10,000, you have 15 days from the date you received the payment that pushed the total over the threshold. For instance, if someone pays you $6,000 in January, $4,000 in February, and $2,000 in March, you must file Form 8300 by late February—15 days after receiving the February payment that brought the total above $10,000.

Related Transactions

Any transactions between the same buyer (or their agent) and your business within a 24-hour period are considered related and must be combined. Transactions more than 24 hours apart are still related if you know or have reason to know they're part of a series of connected transactions.

Late Filing

If you miss the 15-day deadline, you must still file Form 8300 and clearly mark it as “LATE.” Filing late doesn't eliminate penalties, but failing to file at all dramatically increases them.

Amended Returns

If you discover errors after filing—such as incorrect dollar amounts, wrong taxpayer identification numbers, or missing information—you should file an amended Form 8300 as soon as possible. Check box 1a at the top of the form to indicate it's an amendment, then complete the entire form with corrected information. Don’t attach a copy of the original report; the amended version replaces it completely.

Key Rules for 2012

Who Must File

Generally, any person or business engaged in a trade or business must file Form 8300 when receiving more than $10,000 in cash. This includes sole proprietors, partnerships, corporations, and exempt organizations conducting business activities. However, if you sell personal property (like your own car) outside your business activity, you don't need to file.

Cash Definition for 2012

Cash means U.S. or foreign currency, plus cashier's checks, bank drafts, traveler's checks, and money orders with face amounts of $10,000 or less if received in a “designated reporting transaction” or when you know the payer is trying to avoid reporting.

Important Exceptions

Certain monetary instruments don’t count as cash: cashier's checks or money orders over $10,000 in face value; proceeds from documented bank loans; and instruments received as part of certain installment plans where the business routinely receives 50% or less of the purchase price within 60 days.

Taxpayer Identification Number (TIN) Requirements

You must obtain and report the correct TIN for everyone from whom you receive cash. If the transaction is conducted on behalf of another person, you need that person’s TIN too. If a customer refuses to provide their TIN, note “customer refused” on the form.

Customer Statement Requirement

By January 31 of the following year, you must send a written or electronic statement to each person named on Form 8300. The statement must include your business information, total reportable cash received, and a statement that the information is being reported to the IRS.

Recordkeeping

Keep copies of all filed Forms 8300 and supporting documentation for at least five years from the filing date.
