MSB Registration: What It Means and What It Requires

Filing FinCEN Form 107 and receiving your MSB registration confirmation feels like the finish line. It is not. Federal registration is the starting point of an ongoing set of compliance obligations that apply to your business for as long as you operate as an MSB. Many businesses register with FinCEN, receive their confirmation, and then set it on a shelf — unaware that registration alone satisfies only one of the many requirements the Bank Secrecy Act imposes.

This guide explains who must register, what registration actually triggers, and what the consequences are for failing to meet the ongoing obligations that registration creates.

Who Is Required to Register

An MSB is defined at 31 CFR 1010.100(ff). Any person who operates as one of the following in the United States must register with FinCEN:

• Money Transmitter Any person that engages in the transfer of funds — including online payment processors, P2P transfer platforms, remittance services, and payment processors. Activity threshold: no minimum dollar amount.
• Check Casher Any person that cashes checks for compensation. Activity threshold: more than $1,000 in a single day for any one person.
• Currency Dealer or Exchanger Any person that exchanges currencies for compensation. Activity threshold: more than $1,000 in a single day for any one person.
• Issuer of Money Orders Any person that issues money orders for compensation. Activity threshold: more than $1,000 in a single day for any one person.
• Seller of Money Orders Any person that sells money orders for compensation. Activity threshold: more than $1,000 in a single day for any one person.
• Issuer of Traveler's Checks Any person that issues traveler's checks for compensation. Activity threshold: more than $1,000 in a single day for any one person.
• Prepaid Access Sellers of prepaid access (e.g., prepaid debit cards) meeting the criteria under 31 CFR 1010.100(ff)(4). Banks and credit unions are excluded from MSB status.

The Registration Process

MSB registration is filed with FinCEN using FinCEN Form 107 (Registration of Money Services Business). The form is filed electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov. There is no filing fee.

A new MSB must register within 180 days of the date it first qualifies as an MSB. This means that if you cash a check for compensation on January 1 and exceed the $1,000 threshold, you have until approximately June 30 to file your registration. Operating as an unregistered MSB is a separate BSA violation, independent of any other compliance failure.

Registrations must be renewed every two years. The renewal window opens 90 days before the expiration of the registration period, and FinCEN sends reminder notices via email. A lapsed registration is visible in the public FinCEN MSB Registrant Search, which means your bank, potential banking partners, and regulators can see that your registration has expired.

What Registration Triggers

FinCEN registration is an administrative act — it tells the federal government that you exist and are operating as an MSB. It does not, by itself, create compliance. The BSA requirements that apply to your business exist independently of whether you have registered. However, registration is the signal that places your business on FinCEN's and the IRS's radar for examination and oversight.

Once registered, your business is subject to the following federal requirements:

Recordkeeping Requirements

BSA records must be retained for five years from the date of the transaction or the date the record was created, whichever is later (31 CFR 1010.430). This includes CTRs, Monetary Instrument Sales Logs, Travel Rule records, CIP records, and OFAC screening records.

Records may be maintained in electronic or paper form. Electronic records must be accessible and retrievable on request from FinCEN, the IRS, or other authorized law enforcement agencies within a reasonable time. Destroying BSA records before the end of the retention period is a separate violation. If you receive a subpoena or legal hold notice, BSA records are almost certainly covered.

State Licensing — A Separate Obligation

FinCEN registration is a federal obligation. It is entirely separate from state money transmitter licensing, which most states require for businesses that transmit money. As of 2026, 49 states and the District of Columbia require money transmitters to hold a state license. The requirements vary significantly by state — bond amounts, net worth requirements, examination schedules, and application fees all differ.

A business that is federally registered with FinCEN but is not licensed in the states where it operates is violating state law and potentially federal law as well (since unlicensed money transmission is a predicate offense under 18 U.S.C. § 1960). FinCEN registration and state licensure are parallel obligations, not alternatives.

Check cashers and currency exchangers face a different state landscape — many states regulate these businesses as well, but the regulatory framework varies more widely than for money transmitters. Consult the specific requirements of each state where you operate.

Penalties for Non-Compliance

Failure to register with FinCEN as an MSB carries criminal penalties under 31 U.S.C. § 5330(e): up to five years imprisonment and fines up to $250,000 per violation. A person who knowingly operates as an unregistered MSB while engaged in money laundering faces up to 10 years imprisonment.

Failure to maintain the compliance program required by registration carries civil money penalties under 31 U.S.C. § 5321 of up to $100,000 per violation per day. Willful violations carry higher penalties. The absence of a written AML program — even at a single-location MSB — is treated as a serious deficiency, not a technical oversight.

Failure to file required CTRs carries civil penalties up to $100,000 per unreported transaction. Each missed CTR is a separate violation. Structuring — deliberately breaking up transactions to avoid the CTR threshold — is a criminal offense under 31 U.S.C. § 5324 carrying up to five years imprisonment per violation, and up to 10 years if the structuring is connected to another federal crime.

What to Do After Registering

If you have recently registered with FinCEN and have not yet built your compliance program, the regulatory clock is already running. The IRS examination program prioritizes newly registered MSBs. The four obligations that must be in place as quickly as possible are:

1. A written BSA/AML compliance program — tailored to your specific MSB type (money transmitter, check casher, etc.), addressing the four pillars of 31 CFR 1022.210, and in use as of the date of registration.
2. A designated compliance officer — a named individual with documented responsibility for managing your BSA compliance program. This person must understand the requirements applicable to your MSB type.
3. Employee training — documented training for every employee who handles transactions or interacts with customers. Training must be conducted before employees handle transactions, not after.
4. Transaction recordkeeping systems — processes to capture the information required for your CTR filings, Monetary Instrument Sales Logs, Travel Rule records, and CIP records from day one of operations.

Registration without compliance is not a stable operating state. The gap between the day you register and the day an IRS examiner selects your business for review may be months or years, but it is not infinite — and the penalties assessed for operating without adequate compliance controls are not scaled to the size of your business.
