Businesses file Form 8300 online through FinCEN’s BSA E-Filing System at bsaefiling.fincen.gov. Any trade or business that receives more than $10,000 in cash in one transaction or in related transactions must submit the form within 15 days of receiving the payment, and any filer required to submit at least 10 information returns in a calendar year has to file it electronically rather than on paper.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 The process is straightforward once you have an account, but the account setup and the information-gathering are where most filers get tripped up.
Set Up Your BSA E-Filing Account First
You can’t file until you’re registered, and registration is not instant. Sign up at bsaefiling.fincen.gov using your Employer Identification Number and contact information for whoever will act as your organization’s system administrator or filing user.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 The account belongs to the business entity, and you designate specific individuals authorized to file on its behalf.
After registering, you’ll get a confirmation email with a User ID and login instructions. Click the confirmation link within five calendar days or the registration expires and you start over.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 Registration can take a few business days to fully process, so don’t wait for a reportable transaction to trigger the setup. A late filing because you couldn’t log in is still a late filing.
What to Collect Before You Open the Form
Most of the work happens before you touch the online form. The information the form asks for has to come from the customer at the time of payment; chasing it down weeks later rarely works.
Know What Counts as Cash
The definition is broader than physical currency. It includes U.S. and foreign coins and currency, and certain monetary instruments with a face value of $10,000 or less: cashier’s checks, bank drafts, traveler’s checks, and money orders. Those instruments count as cash when received in a designated reporting transaction (like a retail sale of a consumer durable good or collectible) or in any transaction where you know the customer is trying to dodge the reporting requirement.2Internal Revenue Service. IRS Form 8300 Reference Guide If any such instrument has a face value above $10,000, it is not treated as cash for this purpose. Personal checks drawn on the payer’s own account are never treated as cash.
Digital assets are now included in the statutory definition of cash under 26 U.S.C. § 6050I.3Office of the Law Revision Counsel. 26 USC 6050I – Returns Relating to Cash Received in Trade or Business Businesses receiving more than $10,000 in cryptocurrency in exchange for goods or services face the same reporting obligation. IRS guidance on the practical mechanics of digital asset reporting continues to develop, so monitor it if you accept crypto.
Watch for Aggregated Payments
You don’t need a single $10,000 payment to trigger the filing. You must file if you receive more than $10,000 from the same payer in two or more related payments within 24 hours, or as part of a single transaction or related transactions within a 12-month period. The 24-hour window is a rolling clock, not a calendar day: 11 a.m. Tuesday to 11 a.m. Wednesday, in the IRS’s own example.4Internal Revenue Service. Understand How to Report Large Cash Transactions
Gather the Payer’s Details
For Part I of the form, you need the payer’s full legal name and complete address, their taxpayer identification number (SSN for individuals, EIN for businesses), an identification document (type, number, and issuing authority), and their occupation or nature of business.
If a customer refuses to provide a TIN, leave the TIN field blank and note “Customer refused to provide EIN” (or SSN) in the Comments Section, item 34. Document your attempts to collect it.2Internal Revenue Service. IRS Form 8300 Reference Guide A refusal does not excuse the filing. You still file with whatever information you have.
Describe the Transaction Specifically
Part II asks for the exact date the cash was received, the total cash amount, and the nature of the transaction (sale of real property, personal property, services, debt repayment, and so on). Include a written description of what changed hands. “2024 Ford F-150 XLT” is more useful than “vehicle.” If multiple payments made up the reportable amount, list the date and amount of each.
If you suspect the payer is structuring payments to stay under $10,000, file anyway and check the suspicious transaction box. The IRS encourages reporting suspicious activity even where the actual amount doesn’t exceed the threshold.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000
Submitting the Form Through the Portal
Log in to the BSA E-Filing System and select Form 8300. The electronic form mirrors the paper version, walking you through Part I (payer), Part II (transaction), and Part III (your business). Select the correct identification type (SSN or EIN) before entering the number, since the system validates the format.
The system runs validation checks as you go and flags mismatched field lengths or missing required entries. That’s a real advantage over paper, where errors surface only after the IRS processes the form. Review everything before submitting. The 15-day clock runs from the date you received the cash, and a rejected submission can push you past that window.
When you submit, the system generates a confirmation page and sends a confirmation email verifying receipt by FinCEN and the IRS.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 Save the confirmation and save a local copy of the completed form itself. Batch filing is available for businesses with a high volume of reportable transactions.
Fixing a Form You Already Submitted
If you catch an error after the fact, file an amended Form 8300 through the same system. Wait until the original is fully acknowledged and assigned a 14-digit BSA ID, usually within two business days of acceptance.5BSA E-Filing System. Support Center
Open your saved local copy of the original filing, remove the signature, change the filing type to indicate an amendment, and enter the BSA ID from the original. Make your corrections, save the file under a new name, re-sign with your PIN, and submit. You can retrieve the BSA ID through the system’s secure messaging inbox, the Track Status feature under the Filing section, or, for supervisory users, the Track Organization Status option.5BSA E-Filing System. Support Center Filing a prompt correction can reduce or eliminate penalties that would otherwise apply.
What You Still Owe After Filing
Filing with FinCEN is only half the job. You must give a written statement to each person named on the form by January 31 of the year following the transaction.3Office of the Law Revision Counsel. 26 USC 6050I – Returns Relating to Cash Received in Trade or Business The statement has to include:
- Your business name, address, and the contact person’s name and phone number
- The total reportable cash you received from that person during the calendar year
- A notice that the information was reported to the IRS
The notification requirement does not apply when you filed voluntarily to report a suspicious transaction below the $10,000 threshold. Tipping off the person there would defeat the purpose.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000
Retain a copy of every filed Form 8300 and supporting documentation for five years from the filing date.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 The confirmation email alone isn’t enough. Keep the form, the confirmation number, copies of any identification documents you collected, and notes on your verification attempts.
Penalties for Filing Late, Wrong, or Not at All
Civil penalties for failing to file a correct Form 8300 are adjusted annually for inflation. For returns due in 2026, filing more than 30 days late but by August 1 costs $130 per form. Filing after August 1, or not at all, costs $340 per form. Intentional disregard raises the penalty to $680 per form.6Internal Revenue Service. Information Return Penalties Separate penalties apply for failing to send the required written statement to the person named on the form.1Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000
Criminal exposure is a different order of magnitude. Willfully failing to file Form 8300 is a felony, not the misdemeanor that applies to most other tax return violations. Individuals face up to five years in prison and a fine of up to $25,000. Corporations face the same prison exposure for responsible officers and fines up to $100,000.7Office of the Law Revision Counsel. 26 USC 7203 – Willful Failure to File Return, Supply Information, or Pay Tax
Structuring transactions to stay under the threshold is a separate crime. Under 31 U.S.C. § 5324, breaking up payments to avoid the reporting requirement carries up to five years in prison, doubling to 10 years if the structuring is part of a broader pattern involving more than $100,000 in a 12-month period.8Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited Those penalties target the person structuring, but a business that knowingly helps a customer structure can face liability under 26 U.S.C. § 6050I(f).3Office of the Law Revision Counsel. 26 USC 6050I – Returns Relating to Cash Received in Trade or Business
