A trade or business generally files IRS Form 8300 when it receives more than $10,000 in cash in one transaction or two or more related transactions.
The reporting rule helps the government detect money laundering and other financial crime. “Cash” includes U.S. and foreign currency and, in designated reporting transactions, certain cashier’s checks, bank drafts, traveler’s checks, and money orders with face amounts of $10,000 or less.

What Is IRS Form 8300?
The $10,000 test is based on the total cash received, not the profit, invoice balance, or amount received on one day. Payments can aggregate when they relate to a single transaction or when the business knows or has reason to know that separate transactions are connected.
Form 8300 is generally due within 15 days after the cash received first exceeds $10,000. Businesses also must furnish an annual written statement to each person named on a required form by January 31 of the following year.
Who Should Use IRS Form 8300?
- Dealers, professional firms, landlords, travel businesses, contractors, and other trades or businesses receiving reportable cash.
- A business receiving installments that cumulatively exceed $10,000 within the aggregation period.
- A seller receiving reportable monetary instruments in a designated reporting transaction.
- Clerks, bookkeepers, managers, and owners responsible for identifying related payments and customer information.
- Not a business reporting cash received by a financial institution under different Bank Secrecy Act rules.
How to Use or Complete IRS Form 8300
- Identify whether the payer’s currency or monetary instrument counts as cash under the rule.
- Aggregate payments from one transaction and related transactions, including installments received by different locations or employees.
- Request and verify the payer’s name, address, taxpayer identification number, and identity document.
- Complete the payer, transaction, payment, business, and suspicious-transaction fields.
- E-file Form 8300 through the authorized system by the 15-day deadline unless a valid exception applies.
- Give the required written statement by January 31 and retain the form and supporting records for five years.
What Counts as Cash?
- Coins and currency of the United States or another country.
- A cashier’s check, bank draft, traveler’s check, or money order with a face amount of $10,000 or less when received in a designated reporting transaction.
- Those monetary instruments in any transaction when the recipient knows they are being used to avoid reporting.
- Generally not a personal check drawn on the payer’s own bank account, a wire transfer, or a monetary instrument with a face amount over $10,000, though other reporting rules can apply.
Related Transactions and Installment Payments
Transactions are related when they occur within 24 hours or when the recipient knows or has reason to know that they are connected. A purchase deliberately split among locations, salespeople, or days can still be one reportable arrangement.
For installment payments, file when cumulative reportable cash first exceeds $10,000. Additional forms can be required when later cash payments exceed another $10,000 threshold within the specified period.
Form 8300 Filing and Customer Statement Deadlines
| Requirement | General deadline |
|---|---|
| File Form 8300 | 15 days after receipt causes total cash to exceed $10,000. |
| Furnish payer statement | January 31 of the following calendar year. |
| Keep records | Five years from filing. |
Suspicious Transactions and Structuring
A business may file a suspicious Form 8300 even when cash does not exceed $10,000. Repeated payments just below the threshold, reluctance to provide identification, or attempts to change payment methods after learning about reporting can be warning signs.
Do not help a customer structure payments to avoid a report. Intentionally causing or assisting avoidance can carry civil and criminal consequences.
Before You File or Submit
- Use the current official version. Tax forms, addresses, thresholds, and electronic filing procedures can change. Download the form or instructions from the issuing agency immediately before use.
- Match names and taxpayer identification numbers. Confirm that legal names, SSNs, ITINs, EINs, plan numbers, and tax periods agree with the related return and agency records.
- Gather supporting records first. Keep calculations, statements, notices, authorizations, appraisals, receipts, and other documents that support every entry.
- Check the deadline and delivery method. An extension to file does not necessarily extend the time to pay. Private carriers also may require a different street address than USPS.
- Sign where required. An unsigned paper form, missing consent, or incomplete electronic authentication can delay or invalidate a submission.
- Keep a complete copy. Retain the filed form, attachments, confirmation number, proof of mailing, fax confirmation, and payment record.
Common Mistakes to Avoid
- Treating each installment or business location as a separate $10,000 test.
- Filing only when cash equals $10,000; the general trigger is more than $10,000.
- Counting every cashier’s check as cash without applying the face-value and transaction rules.
- Missing the separate January 31 written-statement requirement.
- Telling a customer how to divide payments to avoid reporting.
- Discarding identity and transaction records before the five-year retention period ends.
What Happens After Submission?
The e-filing system should provide an acknowledgement. Correct rejected or inaccurate filings promptly under the current electronic correction procedures and keep both the original and correction records.
Maintain a process that aggregates payments across the business and calendar. Training frontline employees is essential because the 15-day period begins when the threshold-crossing payment is received.
Processing time is not the same as a legal deadline. Do not submit a duplicate merely because an acknowledgement or response has not arrived. First check the relevant online status tool, confirmation record, or official contact channel. If the agency requests more information, respond by the date and method stated in the notice.
Records to Keep
Keep a copy of the completed submission and all documents used to prepare it. Your file should also contain the tax-year or period involved, the date submitted, the delivery method, any confirmation or tracking number, and notes about later agency correspondence. Retention periods depend on the form and issue, so follow the specific instructions and keep records longer when they may remain material to an audit, refund claim, basis calculation, collection case, election, or amended return.
Frequently Asked Questions
Is exactly $10,000 reportable?
The general Form 8300 threshold is more than $10,000. Suspicious transactions may be reported voluntarily even below that amount.
Is a wire transfer cash?
Generally no for Form 8300, although financial institutions and businesses may have other reporting or recordkeeping duties.
Must Form 8300 be e-filed?
Businesses generally must e-file Form 8300. Review current waiver and exemption procedures if electronic filing would cause undue hardship or a religious exemption applies.
Should the customer receive a copy of the form?
The business must furnish a written statement containing the required information by January 31. The statement requirement is not always satisfied by handing over the entire form.
Official Resources
Bottom line: Track connected payments across the whole business, file within 15 days once reportable cash exceeds $10,000, send the annual payer statement, and never assist structuring.
