What is the deadline for filing Form 8300?

File Form 8300 by the 15th day after the date the cash was received. For related transactions, the clock starts on the date the cash received first exceeds $10,000 in the aggregate. Late returns must be marked "LATE" in the comments section when e-filing or on the center top of page 1 when paper filing.

What counts as cash for Form 8300?

Cash means United States and foreign coin and currency, plus cashier's checks, bank drafts, traveler's checks, and money orders with a face amount of not more than $10,000 when received in a designated reporting transaction, and digital assets for returns required after December 31, 2023. Personal checks drawn on the writer's own account, wire transfers, and credit or debit card payments are not cash.

What statement must a business give the customer after filing Form 8300?

Under 26 U.S.C. section 6050I(e), the filer must furnish each person named on the return a written statement by January 31 of the year following the reportable transaction, showing the business's name, address, contact person and telephone number, the aggregate amount of reportable cash, and that the information was furnished to the IRS. No statement is furnished when the form was filed voluntarily for a suspicious transaction under the $10,000 threshold with box 1b checked.

What are the penalties for not filing Form 8300?

For returns required to be filed in 2026, the section 6721 penalty is $340 per return, reduced to $60 if corrected within 30 days and $130 if corrected by August 1, 2026, with calendar-year maximums of $4,098,500 or $1,366,000 depending on gross receipts. For intentional disregard of a section 6050I return, the penalty is the greater of $34,150 or the cash received up to $136,500, with no maximum. Criminal prosecution can bring up to five years' imprisonment and fines up to $250,000 for individuals and $500,000 for corporations.

Is splitting a cash payment to stay under $10,000 illegal?

Yes. Structuring is prohibited by 26 U.S.C. section 6050I(f) and 31 U.S.C. section 5324, which bar causing a trade or business to fail to file, causing a false or incomplete return, and structuring or assisting in structuring transactions with trades or businesses or financial institutions to evade reporting. The payments are also related transactions, so the form is due anyway, and the agreement to split is a separate violation.

Does the bank's Currency Transaction Report replace Form 8300?

No. A financial institution files a Currency Transaction Report under 31 CFR 1010.311 for currency transactions over $10,000, while a trade or business that receives the cash files Form 8300 under section 6050I. The same money can be reported from both directions, and neither filing excuses the other.

IRS Form 8300: Cash Transaction Reporting Playbook

A business that takes more than 10,000 dollars in cash has fifteen days to file Form 8300, a written statement to give the customer by January 31, and a structuring ban that punishes splitting the payment. This playbook runs the threshold, the related-transaction rules, and the 2026 penalties.

IRS Form 8300: Cash Transaction Reporting Playbook

A customer pays 12,000 dollars in cash for a used truck. The sale is legal, and so is the cash. What turns the Tuesday into a federal filing obligation is silence: if the dealership files nothing, it has broken the law. The rule is 26 U.S.C. section 6050I, and the form is IRS Form 8300, Report of Cash Payments Over 10,000 dollars Received in a Trade or Business.

Form 8300 does not tax the cash. It reports the receipt so the IRS and FinCEN can trace money moving outside the banking system.

The statute in one paragraph

Section 6050I(a) states the duty in one sentence: a person engaged in a trade or business who receives more than 10,000 dollars in cash in one transaction, or in two or more related transactions, must file the prescribed return: the payer's name, address, and taxpayer identification number, the amount of cash, and the date and nature of the transaction. The same duty appears at 31 U.S.C. section 5331.

26 U.S.C. section 6050I as published on Cornell Law Institute: subsection (a) sets the more-than-10,000-dollar duty, subsection (d) defines cash to include foreign currency, monetary instruments, and digital assets, and subsection (f) prohibits structuring

The trigger is "more than 10,000 dollars." Exactly 10,000 dollars does not trigger Form 8300; 10,001 dollars does. Count related transactions together before you decide the form is not required.

Who must file, and who does not

A "person" who must file includes an individual, company, corporation, partnership, association, trust, or estate. The test is the trade or business, not its size.

Who files is any person in a trade or business: a sole proprietor on an SSN, an LLC, an S-Corp, or a C-Corp, each reporting under its own EIN. The amount reported is the gross cash received — COGS, FICA, and SECA do not reduce it.

Three groups sit outside the duty. Financial institutions do not file Form 8300 for cash they receive; they file a Currency Transaction Report under 31 CFR 1010.311 instead. A transaction that occurs entirely outside the United States is excepted under section 6050I(c)(2). A transaction outside a trade or business does not trigger the form.

Court clerks are a separate class of filer: under section 6050I(g), a clerk who receives more than 10,000 dollars in cash as bail for an individual charged with a specified criminal offense — a controlled-substance offense, racketeering, money laundering, or a similar state offense — must file Form 8300.

What counts as cash

Cash is wider than paper money. Under section 6050I(d), cash means United States and foreign coin and currency, plus monetary instruments of not more than 10,000 dollars received in a designated reporting transaction: a cashier's check, a bank draft, a traveler's check, or a money order. Since 2021, cash also includes any digital asset as defined in section 6045(g)(3)(D), for returns required after December 31, 2023.

A designated reporting transaction is a retail sale, or a broker's receipt in connection with one, of a consumer durable, a collectible, or a travel or entertainment activity: a durable is tangible property reasonably expected to remain useful for at least one year with a sales price over 10,000 dollars; a collectible is any work of art, rug, antique, metal, gem, stamp, coin, or similar item; a travel or entertainment activity pertains to a single trip or event whose combined sales price exceeds 10,000 dollars. The instrument is not cash if it is proceeds of a bank loan, or payment on certain promissory notes, installment sales contracts, or down payment plans. A personal check drawn on the writer's own account is not cash.

Payment received	Counts as cash for Form 8300?	Authority
United States or foreign coin and currency	Yes, always	26 U.S.C. section 6050I(d)(1); Instructions for Form 8300
Cashier's check, bank draft, traveler's check, or money order of 10,000 dollars or less in a designated reporting transaction	Yes	26 U.S.C. section 6050I(d)(2)
Digital asset	Yes, for returns required after December 31, 2023	26 U.S.C. section 6050I(d)(3)
Cash received by a financial institution	No Form 8300; bank files a Currency Transaction Report	31 CFR 1010.311

A cashier's check for 9,000 dollars is cash for Form 8300 purposes when it pays for a consumer durable in a retail sale, even though the check itself is under the threshold. Train the person at the register to ask: is this a designated reporting transaction, and is the instrument one of the four listed kinds?

Related transactions: the 24-hour rule and the longer tail

The threshold is tested on the transaction, not the payment: transactions between a payer, or the payer's agent, and the recipient in a 24-hour period are related, and transactions are related even over more than 24 hours if the recipient knows, or has reason to know, that each is one of a series of connected transactions.

A customer who pays 6,000 dollars on Monday morning and 4,500 dollars that afternoon has made related transactions totalling 10,500 dollars:

\text{Related total} = 6,000 + 4,500 = 10,500\ \text{dollars} > 10,000\ \text{dollars}

The longer tail matters for installment sales: a customer who pays 4,000 dollars in cash each month for three months toward a 12,000-dollar purchase, where the seller knows the payments are parts of one connected sale, has made related transactions.

Branches are separate recipients unless a central office links them; a filer related to the payer must write "RELATED PARTY TRANSACTION" in the Comments section.

The 15-day clock

File Form 8300 by the 15th day after the date the cash was received — for related transactions, the date the cash first exceeds 10,000 dollars in the aggregate. Count calendar days:

\text{Date cash received} = \text{November 3, 2026}

\text{Filing deadline} = \text{November 3} + 15\ \text{days} = \text{November 18, 2026}

A return filed on November 19 is late; mark late returns "LATE" in the comments section when e-filing, on the center top of page 1 when paper filing. Filing in the wrong manner counts as filing late.

Since January 1, 2024, a business must file Forms 8300 electronically if it is required to file at least 10 information returns of types other than Form 8300 during the calendar year: five Forms W-2 and five Forms 1099-INT add to ten, so the business must file electronically; three Forms 1099-MISC and four Forms 1099-DIV add to seven, so it need not. Forms 8300 themselves never count toward the ten. Paper filers mail the form to the Internal Revenue Service, The Rosa Parks Federal Building, P.O. Box 32621, Detroit, MI 48232.

Put the 15-day clock on the receipt, not in someone's head. Stamp it with the date, the running total for that customer, and the filing deadline computed on the spot. A dealership that discovers a reportable receipt on day 20 has already lost the reasonable-cause argument, because the deadline was computable on day one.

The statement you owe the customer

Under section 6050I(e), every filer must furnish a written statement to each person named on the return, showing the name, address, and phone number of the filer's information contact, the aggregate amount of cash received, the business contact person and telephone number, and a note that the information was furnished to the IRS. It must be furnished on or before January 31 of the year following the calendar year of the transaction.

A voluntary suspicious-activity filing under the threshold, with box 1b checked, gets no statement.

Penalties: the arithmetic of a missed form

Failing to file a correct and complete Form 8300 on time, without reasonable cause, draws a penalty under section 6721; failing to furnish a timely, correct, and complete statement draws one under section 6722. Rev. Proc. 2024-40 sets the 2026 figures:

Failure	Penalty per return or statement	Calendar-year maximum
General rule, section 6721	340 dollars	4,098,500 dollars; 1,366,000 dollars for smaller filers
Corrected within 30 days of the required filing date	60 dollars	683,000 dollars or 239,000 dollars
Intentional disregard, return under section 6050I(a)	Greater of 34,150 dollars or the cash received, up to 136,500 dollars	No limit
Failure to furnish payee statement, section 6722	340 dollars per statement	4,098,500 dollars, or 1,366,000 dollars for smaller filers

Three late Forms 8300 corrected within 30 days cost 180 dollars; left uncorrected, the same three cost 1,020 dollars:

\text{Corrected within 30 days} = 3 \times 60 = 180\ \text{dollars}

\text{Uncorrected general rule} = 3 \times 340 = 1,020\ \text{dollars}

Intentional disregard is a different scale: the penalty is the greater of 34,150 dollars or the amount of cash received, up to 136,500 dollars, with no calendar-year maximum. A business that willfully ignores a 48,000-dollar receipt faces a 48,000-dollar penalty on that one return:

\text{Intentional disregard penalty} = \max(34,150, 48,000) = 48,000\ \text{dollars}

The December 2023 instructions print a 25,000-dollar minimum for intentional disregard; 34,150 dollars is the inflation-adjusted amount for 2026 returns under Rev. Proc. 2024-40.

Reasonable cause is narrow: it is generally granted when the person exercised ordinary business care and prudence but was nevertheless unable to comply. A business with no procedure for spotting cash receipts cannot show ordinary business care. Behind the civil penalties sits criminal exposure: causing a failure to file, a report with a material omission, or structuring to avoid the requirements may, upon conviction, bring up to five years' imprisonment or fines of up to 250,000 dollars for individuals and 500,000 dollars for corporations, or both.

Structuring: splitting the payment is the crime

Structuring is breaking a transaction into smaller pieces to evade a reporting requirement. Section 6050I(f)(1) prohibits causing a failure to file, causing a return with a material omission or misstatement, and structuring any transaction with one or more trades or businesses. A violator faces the same sanctions as a person who fails to file or files a false return.

The parallel Title 31 prohibition is 31 U.S.C. section 5324 bars the same structuring with domestic financial institutions, nonfinancial trades or businesses, or any importation or exportation of monetary instruments.

Structuring does not require a completed evasion. A customer who asks a dealer to take 9,000 dollars today and 9,000 dollars tomorrow "so no form is needed" has proposed structuring, and a dealer who agrees has joined it. The two payments are related transactions anyway, so the form is due, and the agreement to split is a separate violation.

Founder & CEO Insight — Enow A. Jovial

"The cash is never the problem. Write the rule down: what counts as cash, the running total for this customer today, and the date the form is due. A business that makes its staff guess at a federal filing deadline is buying penalties one quiet Tuesday at a time."

— Enow A. Jovial, Founder & Chief Executive Officer

FinCEN versus IRS Form 8300: two reports, two filers

The confusion between the bank's report and the business's report is the most common error in this area. A financial institution that handles a currency transaction of more than 10,000 dollars files a Currency Transaction Report under 31 CFR 1010.311. Before concluding the transaction, it must verify and record the identity of the individual presenting it and of any person on whose behalf it is effected, under 31 CFR 1010.312. The mere notation of "known customer" or "bank signature card on file" is prohibited.

A trade or business that receives the same cash files Form 8300 under section 6050I and 31 U.S.C. section 5331. The two reports can cover the same money from two directions: the customer deposits 12,000 dollars at the bank, the bank files a Currency Transaction Report; the customer pays 12,000 dollars in cash to the dealer, the dealer files Form 8300. Neither filing excuses the other.

Our 1099-NEC contractor reporting playbook covers the return a business files when it pays a contractor, and our 1099-K payment app reporting threshold playbook covers the threshold when the same money moves through a payment app instead of in cash.

Worked example: the dealership's week

A used-car dealership sells three cars for cash in one week. On Monday, a customer pays 7,000 dollars in cash and 3,000 dollars by personal check for a 10,000-dollar car. The check is not cash, so no form is due. On Wednesday, a customer pays 6,000 dollars in cash as a deposit on a 14,000-dollar truck, then returns on Thursday with 5,000 dollars more in cash. The two payments are related transactions within 24 hours, the cash total is 11,000 dollars, and one Form 8300 is due, with the clock starting Thursday. On Friday, a customer pays 9,500 dollars with a cashier's check for a 9,500-dollar collectible car. The price is not more than 10,000 dollars, so no form is due.

\text{Wednesday cash} + \text{Thursday cash} = 6,000 + 5,000 = 11,000\ \text{dollars}

\text{Threshold test} = 11,000 > 10,000,\ \text{so one Form 8300 is due}

The dealership files one form for 11,000 dollars and furnishes the January 31 statement. The Monday and Friday sales produce no form, and the dealership keeps the working papers that show why.

Execution checklist: from the register to the filed form

Step 1 — Write the cash rule and tape it at the register. What counts as cash, the threshold, the 24-hour rule, and who decides.
Step 2 — Record every cash receipt the day it happens. Date, payer, amount, and payment form.
Step 3 — Test the threshold on the running total, not the single payment.
Step 4 — Collect the payer's name, address, and taxpayer identification number first.
Step 5 — Compute the filing deadline on the receipt. Add 15 calendar days to the date the cash first exceeded 10,000 dollars.
Step 6 — File within 15 days, electronically if the 10-return rule applies; mark late returns "LATE".
Step 7 — Furnish the written statement by January 31 of the following year, unless the filing was a voluntary suspicious-activity filing.
Step 8 — Keep the copy for five years, with the papers that show why non-reportable receipts were not filed.

Form 8300 is a reporting duty with a hard number, a short clock, and a penalty table that punishes delay. A business that spots the cash, adds the related payments, and files inside 15 days has done the whole job.
