Businesses that receive bank deposits over $10,000 must report these transactions to the Financial Crimes Enforcement Network (FinCEN).
This requirement is mandated by the Bank Secrecy Act (BSA) and is designed to prevent money laundering and other financial crimes.
The IRS considers these large cash transactions to be "cash transactions" and requires businesses to report them on a Form 8300.
Businesses must file this form within 15 days of receiving a cash transaction over $10,000.

Business Reporting Requirements
Businesses must report any cash deposit over $10,000, including lump sum payments and multiple related transactions in a 24-hour or 12-month period. This rule applies to all types of businesses, including corporations, partnerships, and tax-exempt organizations.
If a business receives a cash payment of more than $10,000, the payment must be reported to the IRS using Form 8300. This includes payments made in cash, as well as money orders, traveler's checks, cashier's checks, and bank drafts.

Businesses must also report cash deposits that meet the $10,000 threshold, even if they are made in installments. For example, if a business makes a $4,000 cash deposit on Thursday and another $7,000 cash deposit the next day, the bank must submit a CTR form to the IRS.
Here are the key reporting requirements for businesses:
- Cash payment in a lump sum over $10,000
- $10,000 payment via two or more related transactions in a 24-hour period
- $10,000 payment via two or more related transactions in a 12-month period
It's worth noting that businesses can voluntarily report cash deposits if they suspect "structuring" is taking place. Structuring occurs when a customer splits up cash deposits to avoid reporting requirements.

Bank Deposit Limits
You can deposit a check of more than $10,000, but your bank may apply a temporary hold on the money.
Depositing large checks in person at the teller window usually makes the funds available immediately. However, banks may need to clear the funds through their processing center first, which can delay the availability of the money.
You can deposit up to $10,000 in cash without needing to report the deposit to the IRS, but individual banks may have different limits.

Limit

The limit on cash deposits can be a bit confusing, but it's actually pretty straightforward. The IRS requires you to report any cash deposit over $10,000.
Individual banks may also have their own limits on cash deposits, which can vary depending on the bank and the deposit method. For example, Capital One 360 has a lump-sum deposit maximum of $5,000 at ATMs.
Some banks may have stricter limits, like Chime, which allows only three deposits per day up to a maximum of $1,000 per day, and a $10,000 per month limit when depositing at Walgreens.
The limit on cash deposits can also apply to check deposits of more than $10,000. In this case, your bank will still report the deposit to the IRS, but may apply a temporary hold on your money.
Here's a look at some sample cash deposit limits from different banks:
*Note that while Alliant Credit Union's cash deposit limit is greater than $10,000, you're still required to report deposits of more than $10,000 to the IRS.
Remember, it's always a good idea to check with your bank to see what their specific limits are, as they can vary.
What Happens When You Overdraft $10,000 Via Check?

Depositing over $10,000 via check is a relatively straightforward process, but it does trigger some extra steps for the bank.
The bank will fill out Form 8300, which is a report that helps regulators prevent financial crime.
To verify your identity, the bank will require additional information from you, which they will document in a Currency Transaction Report.
This report will include all the details of the deposit, including the amount and your identification information.
The bank will file this report within 15 days of the transaction and keep it on file for at least five years.

Consequences of Non-Compliance
Failing to report cash deposits over $10,000 can lead to severe consequences.
You may face a fine ranging from $25,000 to $100,000 if you don't report a large deposit or payment.
The IRS takes non-compliance seriously, and it's essential to understand the requirements and exceptions to avoid any issues.
If you're a tax-exempt organization, you're exempt from reporting charitable contributions in excess of $10,000, but you must still report non-charitable cash payments.
Failure to report can result in financial penalties and damage to your reputation.
Here are some key points to remember:
Penalty for Not Reporting

The penalty for not reporting large cash deposits can be steep. Banks and other entities that fail to report cash deposits or purchases may face a fine ranging from $25,000 to $100,000.
The IRS takes non-compliance seriously, and the penalties can add up quickly. For example, the penalty for negligent non-filing per incidence is $280.
Here are the specific penalties for non-reporting, broken down by intent:
It's worth noting that these penalties can be avoided by simply reporting large cash deposits and purchases in a timely manner. In fact, the article suggests that making the process smoother by contacting your banking institution in advance can help prevent fines altogether.
What Are the Penalties for Splitting Up?
Splitting up large cash deposits can have serious consequences. The IRS may penalize you for intentionally splitting up large cash deposits to avoid bank filing of Form CTR 112.
The penalty amount is determined by the government, and it's best to deposit the money as a whole amount to avoid any issues.
If you've acquired the money legally, it's recommended to deposit it in its entirety to have it all in the bank.
What Happens Next

Once the bank files a report, the IRS shares it with officials from your local and state jurisdictions, up to the national level, to monitor where the money ends up.
The IRS checks the serial numbers on each bill to ensure they're genuine, and if the money is stolen, they double-check those numbers against reports of cash robberies for their investigations.
If you deposit over $10,000 in cash, the bank must file a report, and the IRS will share it with officials from your local and state jurisdictions.
The IRS considers money orders, traveler's checks, cashier's checks, and bank drafts as cash for reporting purposes, just like actual coins and bills.
The bank can choose to file a report on suspicion of structuring, even if the deposits don't fall within 24 hours, and they can do so on suspicion of structuring.
Here are some examples of when a bank might file a report:
The bank has the right and responsibility to determine whether a report is necessary and whether or not they suspect that a customer is structuring.
What Happens When Reported?

If a bank reports a large cash deposit, they file a Currency Transaction Report (CTR) with the Financial Crimes Enforcement Network (FinCEN). This can trigger an IRS investigation.
The IRS may choose to investigate, which could result in penalties, including fines or having the account frozen. If you file a cash deposit report yourself, there's a small chance the IRS may investigate, but you shouldn't face any penalties.
However, if the bank reports your deposit before you do, you may incur a fine or other penalty. It's always recommended to file a report yourself in advance of any large cash deposit.
If you make multiple cash deposits totaling over $10,000 in 24 hours, or if you're suspected of "structuring" deposits, a bank may file a CTR form, even if the deposits don't exceed $10,000 within the 24-hour period.
Here's a summary of the possible outcomes when a bank reports a large cash deposit:
Reporting Process

The reporting process for bank deposits over $10,000 is a bit complex, but I'll break it down for you. If you need to make a cash deposit of more than $10,000, you'll need to properly report it to the IRS.
You can do this by filing IRS Form 8300, which is required for individuals, companies, corporations, partnerships, tax-exempt organizations, and other business structures. Failure to do so may result in a fine ranging from $25,000 to $100,000.
To make the process smoother, it's a good idea to contact your banking institution in advance of the deposit. They'll be able to guide you through the process and ensure everything is done correctly.
Here are some key points to keep in mind:
- Cash deposits over $10,000 must be reported to the IRS using IRS Form 8300.
- Financial institutions must fill out a CTR (Currency Transaction Reporting) Form 112 for deposits over $10,000.
- Purchases made with cash over $10,000 must also be reported using IRS Form 8300.
- Multiple cash deposits totaling over $10,000 in 24 hours must be reported using a CTR form.
- Banks can voluntarily file a CTR form if they suspect you are "structuring" deposits.
The IRS considers the following monetary instruments as cash for reporting purposes:
- Money orders
- Traveler’s checks
- Cashier’s checks
- Bank drafts
Avoiding Reporting
You might think breaking up a large deposit into smaller amounts is a way to avoid getting reported, but it's actually not a good idea. Breaking up a large deposit into smaller amounts to avoid reporting is called "structuring", and it's a crime.

The IRS can penalize banks and other entities that fail to report large cash deposits or purchases, with penalties including $280 for negligent non-filing per incidence and the greater of $28,260 or the amount received in the transaction, up to $113,000 for intentional neglect to file.
If you have over $10,000 that was legally earned and you want to deposit it, make sure to deposit it all at once. Depositing over $10,000 triggers additional verification and process, which is why it's best to just get it done in one go.
The penalties for non-reporting are steep, and it's not worth the risk of getting caught. It's always better to be safe than sorry, and reporting large deposits is a smart business move for banks and other entities.
Here are the penalties for non-reporting in more detail:
Bank Account Monitoring
Bank Account Monitoring is a crucial step in managing large bank deposits over $10,000. It's essential to set up alerts for unusual transactions, such as a $5,000 withdrawal from a coffee shop in New York City.

Most banks offer online monitoring tools that allow you to track your account activity in real-time. This can be especially helpful when dealing with large deposits, such as a $25,000 payment from a client in Los Angeles.
Regularly reviewing your account statements can also help you identify any suspicious activity. For example, a $10,000 deposit from a company in Chicago may raise red flags if you're not expecting it.
You can also use bank account monitoring services to track your account activity across multiple accounts, such as a business account and a personal account. This can be especially helpful for entrepreneurs who need to manage multiple accounts.
It's also a good idea to keep an eye on your account's transaction history, especially if you've made a large deposit, such as a $15,000 payment from a real estate sale in Miami.

BSA and Regulations
The Bank Secrecy Act, also known as the $10,000 Rule, requires banks to report any deposits or withdrawals over $10,000 to the Internal Revenue Service.

This law started in 1970 as the Currency and Foreign Transactions Reporting Act. Banks must fill out IRS Form 8300 for large transactions, which begins the process of Currency Transaction Reporting (CTR).
Any transaction exceeding $10,000 triggers a 15-day reporting period for the bank to notify the government. This is not about suspicion, but rather to prevent illegal activity like theft, money laundering, or funding criminal organizations.
Private businesses must also report large, cash-only transactions, similar to banks. This includes purchases like cars, houses, or other major items.
