CTR (Currency Transaction Report)
Definition
A currency transaction report (CTR) is a report that US financial institutions, including casinos and card clubs, must file with FinCEN, the Treasury's financial intelligence unit, for each transaction in currency of more than $10,000, whether cash in or cash out. For casinos the rule is 31 CFR 1021.311, which lists covered cash-in transactions such as chip purchases, front money deposits, marker payments, bets of currency and bills inserted into gaming machines, and cash-out transactions such as chip redemptions, payments on bets and cheque cashing.
Under 31 CFR 1021.313, multiple transactions by or on behalf of the same person must be added together across a gaming day when the casino knows about them. The report is due within 15 days of the transaction, and copies must be kept for five years under 31 CFR 1010.306. A CTR is a routine record of large cash activity, not an accusation of wrongdoing.
Key takeaways
- A CTR is filed with FinCEN for each cash transaction over $10,000; casinos and card clubs are covered by 31 CFR 1021.311.
- Casinos must aggregate cash in and cash out by or for the same person across a gaming day when they know of the transactions.
- Reports are due within 15 days and copies are kept for five years.
- A CTR is routine and threshold-based, unlike a suspicious activity report, which is driven by suspicion and kept confidential.
Why it matters
For US casinos, CTR compliance is a daily operational process rather than an occasional filing. Cash moves through the casino cage, tables, slot machines and other outlets, and the casino has to capture identity at the right moment and aggregate everything a customer does across its gaming day. That requires player tracking, multiple transaction logs and procedures for collecting identification before a transaction crosses $10,000. Missed, late or incomplete reports can lead to Bank Secrecy Act penalties.
The threshold also shapes criminal behaviour. Because $10,000 is well known, people trying to avoid a report split cash into smaller amounts, which is structuring and is itself a federal offence. Casinos therefore pair CTR processes with transaction monitoring that looks for repeated amounts just below the line and for linked customers.
Online operators meet CTRs where they handle currency, for example cash deposits to an online account made at a casino cage. CTRs are separate from suspicious activity reports: a transaction can require both, one or neither. As of October 2026 the $10,000 threshold remains the federal standard, although FinCEN can lower it in specific areas through geographic targeting orders. The AML and Financial Crime course covers US reporting duties.
CTR (Currency Transaction Report) vs Suspicious activity report (SAR)
| CTR (Currency Transaction Report) | Suspicious activity report (SAR) |
|---|---|
| Threshold-based: required for every cash transaction, or aggregated set of transactions, over $10,000 in a gaming day, regardless of suspicion. | Judgement-based: filed when a casino knows, suspects or has reason to suspect a transaction involves illicit funds, evasion of reporting or has no apparent lawful purpose, and kept confidential. |
Filing a CTR does not discharge the duty to consider a SAR. A customer who deliberately keeps cash under $10,000 generates no CTR but may well require a SAR.
The bottom line
A CTR is the routine US report of cash transactions over $10,000, and casinos must aggregate a customer's cash activity across the gaming day to meet it. It is a record, not an accusation, but missing or late CTRs can lead to enforcement action.

Frequently asked questions
What is a CTR in a casino?
A CTR, or currency transaction report, is a form a US casino files with FinCEN when a customer's cash transactions exceed $10,000 in a gaming day, either cash in, such as buying chips, or cash out, such as redeeming chips or collecting winnings. The casino records the customer's identity and the amounts. Filing is routine and does not mean the customer has done anything wrong.
What is the CTR threshold?
The federal threshold is more than $10,000 in currency. For casinos, cash in and cash out are each aggregated across a gaming day when the transactions are made by or on behalf of the same person and the casino knows of them. FinCEN can require reports at lower amounts in specific places through geographic targeting orders, but the general rule remains $10,000.
CTR vs SAR: what is the difference?
A CTR is automatic once cash transactions exceed $10,000, whatever the circumstances. A SAR is filed only when the institution suspects that activity may involve illicit funds, evasion of reporting or another crime, and its existence must not be disclosed to the customer. One transaction can lead to a CTR, a SAR, both or neither.
Do CTRs apply to online gambling?
CTRs apply to transactions in currency, meaning physical cash. Most online deposits use cards, bank transfers or e-wallets, which are not currency transactions. CTR duties arise for online accounts where cash is involved, for example when a player deposits or withdraws cash at a casino cage linked to their online account. Online operators still have suspicious activity reporting duties.
