When a Business Must File IRS Form 8300 for Cash Payments

A business that receives more than $10,000 in cash in one transaction or related transactions generally must file Form 8300. The hard part is often identifying which payments count together and which receipt starts the filing clock. The governing rules include 26 U.S.C. § 6050I and Treas. Reg. § 1.6050I-1. The IRS reference guide supplies worked examples and current filing instructions.

Identify the recipient, transaction, and form of payment

The reporting duty ordinarily falls on a person receiving cash in the course of a trade or business. Start with the invoice, contract, receipt, payer identity, and payment instrument. Currency is cash; a personal check generally is not. A cashier’s check, bank draft, traveler’s check, or money order with a face amount of $10,000 or less can count as cash in a designated retail transaction, including certain sales of consumer durables or collectibles or certain travel and entertainment services. An instrument can also count when the recipient knows it is being used to avoid reporting. The instrument rule depends on the actual transaction and knowledge, so do not classify all checks alike.

Aggregate related payments before testing the $10,000 threshold

The trigger is more than $10,000, not exactly $10,000. Payments within a 24-hour period from the same buyer in related transactions are treated together. Payments separated by more than 24 hours can still be related when the recipient knows or has reason to know that they are connected. Installments on one purchase are an obvious example. Unrelated purchases by different customers are not added merely because they occurred on the same day.

For example, $3,000, $4,000, and $4,500 in currency paid on successive dates toward one purchase first exceed $10,000 when the third payment arrives. The business should preserve the dates, amounts, payer information, and reason for treating the payments as related. The IRS guide also explains how to track additional payments after an initial Form 8300: Once later cash payments from the buyer again exceed $10,000 within a 12-month period, another filing may be required. Reconcile the actual sequence before assuming one filing covers every later installment.

Calendar the filing deadline from the triggering receipt

Form 8300 generally is due within 15 days after the payment that causes the reportable amount to exceed $10,000. Under the IRS guide, a deadline falling on a Saturday, Sunday, or legal holiday moves to the next business day. For installment transactions, do not count 15 days from the original contract date or the first smaller payment. Calculate from the receipt that crosses the threshold, retain proof of filing, and check the current form instructions for any special situation.

Check the separate electronic-filing rule

The IRS generally requires electronic Form 8300 filing when the business is required to file at least 10 information returns of other types during the calendar year. Forms 8300 are excluded from that count. The IRS guide identifies FinCEN’s BSA E-Filing System as the electronic submission channel and describes waiver or exemption procedures where applicable. Count the business’s other required information returns before deciding whether paper submission is permitted; the $10,000 cash threshold alone does not answer that question.

Separate the customer statement from a suspicious-activity report

For a required Form 8300, the recipient generally must furnish a written statement to each person identified on it by January 31 of the following year. The statement identifies the reporting business, its contact information, the aggregate reportable cash received during the year, and that the information was reported to the IRS. The IRS guide describes a different treatment for a voluntary report of suspicious activity involving $10,000 or less: A customer statement is not required for that voluntary filing. The guide also warns against giving a customer a copy of the form with the suspicious-transaction box checked or otherwise revealing a confidential suspicious filing. Determine the duty from the particular filing; do not assume that every suspicious notation creates the same notice result.

Keep the supporting payment trail

The IRS guide calls for retaining a copy of the filed Form 8300 for five years. In practice, preserve the invoices, receipts, instruments, dates, and aggregation worksheet that explain why the business did or did not file. Those records make it possible to reconstruct the triggering receipt, filing date, and January statement if the account is later examined.
