MSB Bank Account Requirements: FinCEN, Licenses, and AML Program

Opening a bank account for a money services business comes down to proving three things on paper before you ever speak to a banker: that you are properly registered with FinCEN, that you hold every state license your activities require, and that you run a written anti-money laundering program the bank’s compliance team can actually read and verify. Those are the core MSB bank account requirements, and everything else in the application, from the interview to the site visit, is the bank checking whether the paperwork matches the operation. Federal regulators have told banks they are “neither prohibited nor discouraged from providing banking services to customers of any specific class or type” and should evaluate risk case by case,¹ but in practice a bank will only take the risk on a business whose compliance file is complete and coherent.

Confirm Your Business Is Actually an MSB

Federal regulations under 31 CFR 1010.100(ff) define seven categories of MSB activity. Dealing in foreign exchange, cashing checks, and issuing or selling traveler’s checks or money orders only trigger MSB status when daily volume exceeds $1,000 per customer. Money transmission and providing prepaid access have no dollar threshold at all. If your business accepts funds from one person and sends them to another by any means, you are a money transmitter whether the amount is $50 or $50,000.²

Storefront, website, or mobile app, the classification is the same. Banks, entities registered with the SEC or CFTC, and the U.S. Postal Service are explicitly excluded from the MSB definition.³

Cryptocurrency operators fall inside the definition. FinCEN treats a business that exchanges virtual currency for real currency, or one virtual currency for another, as a money transmitter, and the same applies to anyone who issues a convertible virtual currency and can pull it back out of circulation. The regulations draw no distinction between real currencies and convertible virtual currencies.⁴

Federal Registration With FinCEN

Every MSB must register with the Financial Crimes Enforcement Network by filing FinCEN Form 107 through the BSA E-Filing System within 180 days of starting operations.³ The form asks for the legal name and address of the business, identification details for every owner or controlling person (date of birth and government-issued ID numbers included), the types of MSB activities you perform, and the number of branches and agents.⁵

Form 107 also requires information about your primary transaction bank account, including the financial institution’s name, address, and account number. You must keep a copy of the registration along with supporting documentation at a U.S. location, including an annual estimate of transaction volume and a list of any shareholders holding more than five percent of the company.⁵

Registration must be renewed every two years, on or before December 31 of the renewal year.⁶ A business that serves only as an agent for another registered MSB does not need its own registration, but a company that conducts MSB activities both independently and as an agent must register.³

State Money Transmitter Licenses

Federal registration alone is not enough. Nearly every state requires a separate money transmitter license before you can operate within its borders. Each has its own application process, background checks on owners and key personnel, and financial requirements that vary significantly. Application fees generally run from a few hundred dollars to several thousand, and most states require a surety bond designed to protect consumers if the business mishandles funds. Bond amounts typically range from $50,000 to $2,000,000 depending on the state and your business volume.

Many states use the Nationwide Multistate Licensing System to manage money transmitter applications, renewals, and compliance filings. NMLS centralizes the process so you can submit applications for multiple states through a single platform, though each state still evaluates your application under its own criteria. Some states also require proof that the business maintains a minimum net worth or holds certain liquid assets like cash or certificates of deposit to cover outstanding transmission obligations.

Banks verify that your state licenses are active and in good standing before reviewing an application. A lapsed license in even one state where you operate can be enough for a bank to deny or terminate the relationship.

The AML Program the Bank Will Actually Read

Every MSB must maintain a written anti-money laundering program that meets 31 CFR 1022.210. This is the single most important document a bank reviews when deciding whether to open your account. The regulation requires four specific elements, and banks expect each one to be detailed and operational.⁷

Internal policies and controls: written procedures for verifying customer identity, filing reports, creating and retaining records, and responding to law enforcement requests. These need to be specific to your business model, not boilerplate.⁷
A designated compliance officer: a named individual responsible for day-to-day BSA compliance, including filing reports, keeping records current, tracking regulatory changes, and making sure staff receive adequate training.⁷
Employee training: documented training for all personnel whose duties touch BSA compliance, tailored to each employee’s specific responsibilities rather than a one-size-fits-all deck.
Independent review: a periodic assessment of the program’s effectiveness, ideally performed by someone outside the compliance function, evaluating whether the business is actually following its own procedures.⁸

This is where most applications succeed or fail. A bank can tolerate a business that handles large cash volumes if the AML program shows genuine, detailed controls. A vague or generic program signals that the business treats compliance as a checkbox exercise, and no compliance officer at a bank will approve that.

What Goes in Your Application Package

Banks that accept MSB clients expect a comprehensive documentation package upfront. Beyond the AML program, assemble supporting materials that show your legitimacy and operational transparency. The compliance department reviews this file before you ever get to an interview.

Your package should include your FinCEN registration confirmation, copies of all active state licenses, articles of incorporation or organization, current government-issued photo identification for every principal, and proof of any required surety bonds or insurance coverage. The bank will also want a detailed description of your customer base, the geographic markets you serve, the types of transactions you process, and your expected monthly volume. Your Know Your Customer procedures deserve particular attention. The bank wants to see the specific methods you use to verify customer identities and trace the sources of their funds.

Organize all of this into a clean, indexed file. Compliance reviewers process these applications alongside dozens of others, and a disorganized submission signals operational sloppiness. Every missing document creates another follow-up cycle that pushes your timeline further out.

What the Bank’s Review Looks Like

Submitting the application starts an intensive review period. Compliance officers verify every detail: they confirm your FinCEN registration is active, check the status of each state license, review your AML program for substance, and assess whether your projected transaction volumes match your business model.

Expect a formal interview where you walk through your compliance systems. The bank wants to hear you explain your transaction monitoring process, how you handle suspicious activity, and how you train employees. If the owner cannot articulate the basics of BSA compliance, the bank reads that as risk.

Many banks also conduct physical site visits, particularly for businesses that handle cash. Reviewers check that the physical operation matches the application: security measures, signage, how cash is stored and counted, and whether the workspace is consistent with a legitimate financial services operation. The full review generally takes one to three months, depending on the complexity of your business and the bank’s internal queue. Some banks issue conditional approvals that set monthly volume caps or require more frequent reporting during an initial monitoring period. Monthly maintenance fees for MSB accounts often run significantly higher than standard business accounts because of the compliance burden the bank absorbs.

Reporting Obligations Your Bank Will Monitor

Once the account is open, the reporting obligations are immediate and ongoing. Missing a filing deadline or failing to flag a reportable transaction gets accounts closed and draws enforcement attention.

Suspicious Activity Reports

An MSB must file a Suspicious Activity Report for any transaction, or pattern of transactions, involving $2,000 or more that raises a red flag. The regulation identifies three triggers: the transaction appears to involve funds from illegal activity, it seems designed to evade BSA reporting requirements, or it serves no apparent business or lawful purpose after you examine the available facts.⁹ The SAR must be filed through the BSA E-Filing System. Failing to file SARs is one of the fastest ways to lose a banking relationship, because the bank itself faces regulatory consequences if it maintains an account for an MSB that isn’t reporting properly.

Currency Transaction Reports

Any cash transaction exceeding $10,000 requires a Currency Transaction Report, including aggregated transactions by or on behalf of the same person during a single business day. CTRs must be filed within 15 calendar days of the transaction.¹⁰ For businesses handling heavy cash volumes, CTR filing becomes part of daily operations.

IRS Form 8300

Separately from CTRs, federal law requires any person in a trade or business to file IRS Form 8300 when they receive more than $10,000 in cash in a single transaction or in related transactions. If a customer makes multiple payments that add up past $10,000, another Form 8300 is required each time the running total crosses that threshold. The form must be filed within 15 days after receiving the cash, and a copy must be retained for five years.¹¹

The Travel Rule

For fund transfers of $3,000 or more, the BSA’s Travel Rule requires the transmitting institution to pass along specific identifying information with the transfer, including the sender’s name, account number, and address. This applies to both banks and nonbank financial institutions, so MSBs that transmit funds are directly covered.¹² Your compliance systems need to capture and transmit this data automatically for every qualifying transfer.

Keeping the Account After Approval

Getting the account is only half the battle. MSB accounts get closed far more often than they get denied at the outset, usually because compliance slips after the initial approval period.

Your bank will conduct periodic reviews of account activity, comparing actual transaction patterns against the risk profile you presented during the application. Unexplained spikes in volume, transactions to new geographic regions you did not disclose, or shifts in the types of services you offer can all trigger a review. When that happens, the bank expects a prompt, clear explanation. Silence or vague responses are treated as red flags.

An updated independent review of your AML program should be completed annually and shared with your banking partner. Your compliance officer should maintain a regular line of communication with the bank’s MSB relationship team rather than waiting for the bank to call. Employee training logs should be kept current. Any structural change to your business, whether new owners, additional locations, new state licenses, or a shift from domestic to international transfers, needs to be communicated to the bank before or immediately after it takes effect.

The most common reason MSB accounts get terminated is not fraud; it’s the appearance of inattention. Banks absorb real compliance costs to maintain these relationships, and when a business stops responding to document requests, misses SAR filings, or lets licenses lapse, the bank has every incentive to cut the relationship rather than risk regulatory scrutiny of its own.¹³ Keep thorough records of every transaction, every compliance action, and every communication with your bank, and you can answer questions during reviews without scrambling to reconstruct a paper trail.
