AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A US trade or business that receives more than $10,000 in cash in one transaction, or in related transactions, must file Form 8300 with the IRS within 15 days of receiving it. It must also send a written statement to each person named on the form by January 31 of the following year and keep a copy for five years. An AI agent can spot and add up related cash receipts, but deciding whether payments are related, and anything suspicious, needs a person.
Who has to file
The rule is not limited to banks. It applies to any trade or business that receives the cash in the course of that business: car dealers, jewellers, contractors, landlords, law firms, private schools, event venues. If a customer pays more than $10,000 in cash, the business must report it, however legitimate the customer.
The report goes to the IRS and is shared with FinCEN. It exists so that large cash movements leave a trail. It is not an accusation, and most filings concern ordinary purchases.
What counts as cash and what counts as related
| Item | General treatment |
|---|---|
| US and foreign coins and currency | Cash |
| Cashier's checks, bank drafts, traveler's checks or money orders with a face amount of $10,000 or less | Cash when received in certain transactions, such as consumer purchases of high value items, or when the business knows they are used to avoid reporting |
| Personal checks and wire transfers | Generally not cash for Form 8300 |
| Several payments from one buyer within 24 hours | Treated as one transaction |
| Payments more than 24 hours apart that the business knows are connected | Related, so they are added together |
Instalments matter. If a customer pays a deposit of $4,000 in cash and later $7,000 in cash towards the same purchase, the business files within 15 days of the payment that takes the total over $10,000. Later cash payments in the same 12 months are added up again once they pass a further $10,000.
Deadlines and records
- File Form 8300 within 15 days of receiving the payment that triggers the report.
- Send a written statement to each person named on the form by January 31 of the following year.
- Keep a copy of each form for five years from the date of filing.
- File electronically if you are required to file 10 or more information returns in the year, under IRS e-filing rules; others may file on paper or online.
Breaking a payment into smaller amounts to avoid the report, whether by the customer or the business, is structuring, which is illegal. A business may also file voluntarily for any suspicious cash transaction below $10,000.
What an AI agent can do
- Read cash receipts in the books and flag any single receipt over $10,000.
- Link receipts by customer, invoice and date, and add up related payments within 24 hours and over 12 months.
- Start a 15-day clock on the triggering payment and collect the payer's details the form needs.
- Draft the form and the January 31 statement for a person to check.
- Hold each filed copy with a retention date five years on.
- Flag patterns such as several payments just under $10,000 to a person for review.
What stays with a person
Whether two payments are related depends on what the business knows, which may sit in a conversation rather than in the books. Whether a pattern is suspicious is a judgement. The agent should raise the question, attach the evidence and stop. It should never advise a customer how to pay to avoid a report, and should refuse if asked.
Worked example
Example only. A used-car dealer in Texas sells a truck for $18,500. The buyer pays $6,000 in cash on 2 May and $6,500 in cash on 9 May, with the balance by personal check. The agent links both cash receipts to the same sale. On 9 May the cash total reaches $12,500, so it opens a Form 8300 case due by 24 May, attaches the buyer's ID and taxpayer number from the deal file, and drafts the form. The owner reviews and files on 12 May. The agent diaries the buyer statement for January 31 and the retention date.
Setting up so nothing is missed
Most late Form 8300 filings happen because nobody connected two cash payments, or because the payment was taken by a salesperson who did not know the rule. A few settings make the agent's job, and the owner's, much easier.
- Record every cash receipt against a customer and an invoice, never as unallocated takings.
- Collect the payer's name, address, date of birth, occupation and taxpayer identification number at the point of sale when a large cash payment is likely.
- Train staff that a customer asking about reporting limits, or offering to split a payment, is something to tell the owner about, not something to help with.
- Review the agent's related-payment rules once a year with your accountant, so they match how your business sells.
- Keep the filed forms, the buyer statements and the supporting documents together, so an IRS examination finds one complete file.
Penalties apply for late or incorrect filings, and they are higher where a failure is intentional. Filing on time with accurate details is far cheaper than any penalty.

Questions people ask
Does Form 8300 apply to a wire transfer over $10,000?
Generally no. Wires and personal checks are not cash for Form 8300, though some cash equivalents like money orders can be in certain transactions.
What if the cash arrives in several payments?
Related payments are added together. File within 15 days of the payment that takes the total over $10,000.
Do I tell the customer I filed?
Yes. You must send each person named a written statement by January 31 of the following year. Separately, you may file voluntarily on suspicious transactions.
Can an AI agent file Form 8300 for me?
It can draft and track the form, but a person should check the facts, decide whether payments are related and submit it.
