If your business accepts large cash payments, you may need to do more than report income on your tax return. U.S. law requires many businesses to file Form 8300 whenever they receive more than $10,000 in cash in a single transaction or in related transactions. Below we’ll explain who must file, what counts as “cash,” how and when to file, and what penalties apply.
Who must file Form 8300?
Any “person” engaged in a trade or business that receives >$10,000 in cash must file. “Person” is broad—it includes an individual, company, corporation, partnership, association, trust, or estate. IRS+1
What are “related transactions”? Payments from the same payer to the same recipient within a 24-hour period are related. They can also be related beyond 24 hours if you know (or have reason to know) they are part of a series of connected transactions. IRS
Filing deadline: File within 15 days after receiving the cash that triggers reporting. IRS
What counts as “cash” for Form 8300?
-
U.S. and foreign currency (paper money/coins).
-
Cash equivalents: certain cashier’s checks, bank drafts, money orders, and traveler’s checks with a face value of $10,000 or less when used in a designated reporting transaction (e.g., retail sale of a car/boat, collectibles, travel/entertainment) or when you know the customer is attempting to avoid reporting. IRS
Does a single $12,000 cashier’s check count as cash? No—monetary instruments over $10,000 by themselves are not cash for Form 8300. But a $6,000 cashier’s check + $6,000 currency for one sale does count (total >$10,000). IRS
Are wires or personal checks cash? No. Personal checks and bank wires/ACH are not cash for Form 8300. (Financial institutions separately report large currency transactions via FinCEN Currency Transaction Reports.) IRS
What about crypto/digital assets? Although a 2021 law added “digital assets” to the cash definition, the IRS announced transition relief—do not report digital-asset receipts on Form 8300 until regulations are issued (Announcement 2024-4). IRS+1
How to file in 2025 (e-file rules)
-
E-file required if you must e-file other information returns (like W-2s/1099s) or if you file at least 10 information returns (other than Form 8300) during the year. The number of Forms 8300 you file does not count toward that 10-return threshold. IRS
-
File electronically through FinCEN’s BSA E-Filing System; batch e-filing is available and helpful if you submit many forms. Waivers (Form 8508) and a religious exemption exist for e-filing. IRS+1
Penalties for noncompliance (2025)
-
Per-return penalties under IRC §6721 vary by lateness; for 2025, the penalty is up to $330 per form if filed after August 1 or not filed at all; intentional disregard can be $660 per return (general information-return grid). IRS
-
Form 8300 has much steeper “intentional disregard” penalties: the greater of $31,520 or the amount of cash received, capped at $126,000 per failure (no annual cap). IRS
-
Real-world example: In T.C. Memo 2025-38, an Arizona auto dealer lost a reasonable-cause argument and faced $118,140 in penalties for missing hundreds of Forms 8300. Current Federal Tax Developments+1
Recordkeeping & customer notices
-
Keep a copy of every Form 8300 (plus supporting documents and required customer statements) for five years.
-
E-file confirmations don’t satisfy the recordkeeping rule—save/print the actual form and associate the confirmation number with it.
-
You must send a written statement to each person named on the form by January 31 of the year following the cash receipt. IRS+1
Quick compliance checklist
-
☐ Train staff to spot related transactions and the 24-hour rule. IRS
-
☐ E-file via BSA E-Filing and set up batch filing if you submit many forms. IRS
-
☐ File within 15 days of receipt that pushes you over $10,000. IRS
-
☐ Verify and collect TINs for payers; document attempts if a customer refuses. IRS
-
☐ Save copies for 5 years; confirmations alone are not enough. IRS
FAQs
Do installment payments trigger Form 8300?
Yes. Add cash installments made within one year of the first payment. When cumulative cash exceeds $10,000, file within 15 days of the payment that crosses the threshold. You must file again if additional cash exceeds another $10,000 within a 12-month period. IRS
Do colleges or contractors have to file?
Yes—colleges/universities and contractors must file Form 8300 when they receive >$10,000 in cash (subject to the standard rules). IRS
If I take a $12,000 wire plus $4,000 cash, do I file?
No, because wires aren’t cash; with only $4,000 currency, the cash portion didn’t exceed $10,000. (But stay alert for combinations with small cashier’s checks/money orders that could push you over.) IRS
Should I report crypto I received in 2025?
Not on Form 8300 at this time. The IRS says businesses don’t need to report digital-asset receipts on Form 8300 until regulations are issued. IRS
