Form 8300: Reporting Cash Payments Over $10,000
Form 8300 is the IRS and FinCEN report a trade or business files after receiving more than $10,000 in cash in one transaction or in related transactions. You file it within 15 days of the payment, e-file it if you already e-file 10 or more other information returns, and send the customer a written statement by January 31 of the following year. It is a reporting duty, not a tax.
The rule sits in Internal Revenue Code Section 6050I. It is designed to surface large cash flows to the IRS and the Financial Crimes Enforcement Network (FinCEN), the same data trail that supports money-laundering and tax-evasion investigations. Filing is the business’s job, and the penalties for skipping it can exceed the cash received.
What Form 8300 is and who files it
Form 8300, “Report of Cash Payments Over $10,000 Received in a Trade or Business,” is filed by any person engaged in a trade or business that receives more than $10,000 in cash from one buyer. “Person” includes an individual, company, corporation, partnership, association, trust, or estate. The buyer does not file; the recipient does.
Common filers include auto and boat dealers, jewelers, art and antique dealers, real estate professionals, attorneys, and pawnbrokers. Any cash-taking business can trip the threshold, so the obligation is broad rather than industry-specific.
The report goes to the IRS, and the data is shared with FinCEN. Filing does not accuse the customer of anything. It records a fact: a large cash payment happened.
The $10,000 trigger and related transactions
The duty starts when a business receives more than $10,000 in cash from one buyer, either in a single transaction or in two or more related transactions. Exactly $10,000 does not trigger it; the amount must exceed $10,000. The count can build up over time, not just in one payment.
Related transactions are payments connected to one another. Two rules define them:
| Rule | What it means | Example |
|---|---|---|
| 24-hour rule | Multiple cash payments from the same buyer within any 24-hour period are treated as one | Two $6,000 cash payments 8 hours apart total $12,000 and require filing |
| Known-series rule | Payments more than 24 hours apart still count together when the business knows, or has reason to know, they are part of one series | 6 monthly $2,000 cash installments on one car, tracked as one sale |
Installment sales matter here. If a customer pays for one item in cash pieces and the running total crosses $10,000 within a 12-month period, you file within 15 days of the payment that pushes it over. Each time later payments again add more than $10,000, you file another Form 8300.
What counts as cash
For Form 8300, cash means U.S. and foreign coins and currency. It also includes cashier’s checks, bank drafts, traveler’s checks, and money orders with a face amount of $10,000 or less, but only in specific situations. Personal checks, wire transfers, and monetary instruments over $10,000 in face value are not cash for this form.
Those monetary instruments count as cash only when received in a “designated reporting transaction” or when the business knows the customer is trying to avoid the report. Designated reporting transactions are retail sales of:
- Consumer durables (items priced over $10,000 suited to personal use and lasting at least a year, such as a car or boat)
- Collectibles (art, rugs, antiques, metals, gems, stamps, coins)
- Travel or entertainment sold as one trip or one event totaling over $10,000
The reason a bank instrument over $10,000 is excluded: the bank already reports it, so counting it again would double-report the same money. A personal check clears through the banking system and leaves its own trail, which is why it is never treated as cash on this form.
The 15-day filing deadline
Form 8300 must be filed within 15 days after the date the business receives the cash that pushes the total over $10,000. If the 15th day lands on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day.
For related transactions, the clock can start on a later payment. When earlier cash payments were under the threshold and a new payment crosses $10,000, the 15-day window runs from that crossing payment, not from the first dollar received.
Missing the window is a filing failure even if you file eventually. The penalty tiers below scale with how late you are, so a report filed on day 20 costs less than one filed months later or never.
The e-filing mandate
Since January 1, 2024, a business must e-file Form 8300 if it is required to file at least 10 information returns of any type other than Form 8300 during the calendar year. Forms in the 1099 series, W-2s, and similar returns count toward the 10; Forms 8300 themselves do not. Businesses under the threshold may still file on paper.
E-filing goes through FinCEN’s Bank Secrecy Act (BSA) E-Filing System, which is free. The confirmation email does not satisfy the record-keeping rule, so save or print the completed form before you submit it.
| Situation | How to file |
|---|---|
| 10+ other information returns in the year | Must e-file via the BSA E-Filing System (free) |
| Under 10 other information returns | May e-file, or mail paper Form 8300 to the IRS in Detroit, MI |
| Undue hardship with e-filing | Request a waiver on Form 8508; mark “WAIVER” on page 1 of a paper Form 8300 |
| Religious objection to the technology | Exemption applies automatically; mark “RELIGIOUS EXEMPTION” on page 1 |
The written statement to the customer
A business that files Form 8300 must also send a written statement to each person named on the form, on or before January 31 of the year after the reportable cash was received. This is a separate duty from filing, and missing it draws its own penalty. Voluntary reports of suspicious transactions do not require a statement.
The statement must include:
- The business’s name, address, and a contact person with a telephone number
- The total amount of reportable cash received from that customer in the 12-month period
- A line stating the information is being reported to the IRS
You do not send the actual Form 8300 to the customer. A short letter carrying the required details is enough, and keeping proof that you sent it protects you if the statement penalty is ever questioned.
Penalties for getting it wrong
Penalties fall into two civil buckets, filing failures under IRC Section 6721 and customer-statement failures under Section 6722, plus criminal exposure for willful violations. The figures below are the inflation-adjusted amounts the IRS has published for recent return years and may be adjusted again for later years.
| Failure | Standard penalty | If intentional disregard |
|---|---|---|
| Late or missing Form 8300 (Sec. 6721) | About $310 per return, or $60 if corrected within 30 days | Greater of about $31,520 or the cash received, up to about $126,000 per failure, with no annual cap |
| Late or missing customer statement (Sec. 6722) | About $310 per statement, reduced if corrected early | About $570 per failure, or 10% of the reportable amount, with no annual cap |
Two things make these penalties bite. First, the filing and statement failures stack, so one mistake can generate two penalties. Second, “intentional disregard” removes the annual ceiling and can reach or exceed the cash you took in. Willful failure to file can also be a criminal matter under IRC Section 7203 (up to 5 years), and filing a knowingly false Form 8300 is a felony under Section 7206. A de minimis error of $100 or less in a dollar amount generally does not trigger a penalty.
Recordkeeping
Keep a copy of every Form 8300 you file, plus supporting documentation and a copy of the customer statement, for five years from the filing date. The IRS may ask for these during an examination, and a saved copy is the only accepted proof of what you filed. Because the e-file confirmation email does not count as a record, the saved form is what matters.
Good records also help you defend against a penalty. If you can show the form was filed and the statement was sent on time, you close off both civil penalty tracks.
Frequently asked questions
Does receiving exactly $10,000 in cash require Form 8300?
No. The trigger is more than $10,000, so a payment of exactly $10,000 does not require filing on its own. The moment cash from one buyer exceeds $10,000, in one payment or in related payments, the duty applies. Watch running totals on installment sales, because later payments can push a previously under-threshold customer over the line.
Is a personal check considered cash on Form 8300?
No. Personal checks are never cash for Form 8300, regardless of amount, because they clear through the banking system and leave their own record. Cashier’s checks, money orders, and similar instruments count as cash only when $10,000 or less and received in a designated reporting transaction or a known avoidance attempt. Wire transfers are also excluded.
What happens after a business files Form 8300 on me?
The IRS and FinCEN receive a record that a large cash payment occurred, and the business must send you a written statement by January 31 of the following year. A filing is not an accusation and often has no consequence for a lawful buyer. It can, in many cases, prompt questions if the cash does not match your reported income, so keeping documentation of the payment’s source is sensible.
Can I file Form 8300 on paper instead of electronically?
Sometimes. You may file on paper if you are not required to file at least 10 other information returns during the year. If you cross that 10-return threshold, you generally must e-file through FinCEN’s free BSA E-Filing System unless you hold a hardship waiver (Form 8508) or a religious exemption, which you note on page 1 of the paper form.
How late can Form 8300 be before penalties climb?
The 15-day deadline runs from the date you received the qualifying cash. Filing after that is a failure, but correcting it within 30 days generally cuts the penalty to about $60 per return. Standard late penalties run near $310 per return, and intentional disregard removes the annual cap and can reach the greater of about $31,520 or the cash received, up to about $126,000 per failure.
Do I have to tell the customer I filed Form 8300?
Yes. You must send each person named on the form a written statement by January 31 of the following year, showing your business name, address, a contact and phone number, the total reportable cash, and a note that the information went to the IRS. You send a statement, not the form itself. Skipping it is a separate penalty under IRC Section 6722, so treat it as a required step, not a courtesy.
