MSB Registration

The mechanics of FinCEN MSB registration are straightforward, which is exactly why it should never be the bottleneck in a licensing program.

FinCEN defines a money services business at 31 CFR 1010.100(ff) as a person doing business in one or more of six regulated capacities (the regulation also lists the U.S. Postal Service, which registers under different rules). Three categories carry a dollar threshold of more than $1,000 per person per day; money transmission has no threshold at all. Banks, and companies registered with and functionally regulated by the SEC or CFTC, are excluded from the definition, and a business that acts solely as an agent of another MSB does not file its own registration.

People searching for AML registration or anti-money laundering registration are usually looking at the wrong country's system or the right obligation under a different name. In the United Kingdom, certain businesses literally register for anti-money laundering supervision with HMRC or another supervisor. The United States has no standalone AML register. The US equivalent, for a business that moves or exchanges money, is FinCEN MSB registration: filing Form 107 brings the business under the Bank Secrecy Act, and the written AML program, compliance officer, training, and independent review are conditions of operating as an MSB rather than a separate registration.

So if a bank, partner, or checklist asks for your AML registration and you operate in the US, what you can actually produce is your FinCEN MSB registration number, your written BSA and AML program, and your state money transmitter licenses. Securities firms have their own AML obligations under FINRA rules, and banks under their banking regulators, but for money services businesses the MSB registration on this page is the anti-money laundering registration that exists.

No, and confusing the two is one of the most common and most expensive mistakes new payment companies make. FinCEN registration is a federal notice filing: it tells the Treasury Department you exist and are subject to the Bank Secrecy Act. It costs nothing, takes little time, and is never a grant of operating authority.

A money transmitter license is a state grant of authority to move customer money, with a surety bond, net worth minimum, and application review behind it. Nearly every state requires one before you transmit for residents of that state. A transmitter operating nationwide therefore holds one FinCEN registration and roughly 50 state licenses. Registering with FinCEN and starting to transmit without state licenses is unlicensed money transmission, which carries civil and, in many states, criminal penalties.

The state layer is its own project: almost every state licenses money transmitters through its banking or financial services regulator, most via NMLS, with Montana as the one state that has no money transmitter license statute. Our state-by-state money transmitter law pages at /mtl-state-laws cover each state's bond amount, net worth minimum, and regulator, and /who-needs-a-money-transmitter-license walks through which business models trigger licensing.

Usually, yes. FinCEN's March 2013 guidance on virtual currency (FIN-2013-G001) concluded that administrators and exchangers of convertible virtual currency are money transmitters under the BSA, while a user who buys virtual currency for their own purposes is not. FinCEN's May 2019 consolidated guidance (FIN-2019-G001) applied the same framework to newer models: a platform that accepts and transmits value on behalf of customers, including a custodial exchange or a hosted wallet provider that controls customer private keys, is a money transmitter. Non-custodial software, where the user keeps sole control of the keys and the provider never takes possession of value, generally is not.

The practical consequence: most crypto exchanges, custodial wallet providers, OTC desks, and many stablecoin issuers must register with FinCEN as MSBs within 180 days, build the same AML program, and then face the state licensing map on top. See /crypto-money-transmitter-license for how the state analysis runs for crypto models and /cryptocurrency-licensing for the dedicated state virtual currency regimes.

Operating an MSB without registering carries specific federal exposure, and the numbers are set by statute and adjusted annually for inflation.

On the civil side, 31 U.S.C. 5330(e) sets a penalty of $5,000 per violation as enacted, and each day a registration violation continues counts as a separate violation. Under FinCEN's inflation adjustment rule (31 CFR 1010.821), the maximum is $10,556 per violation for penalties assessed on or after January 17, 2025. On the criminal side, 18 U.S.C. 1960 makes knowingly operating an unlicensed money transmitting business, which includes failing to comply with the FinCEN registration requirement, a federal crime punishable by a fine, up to five years in prison, or both.

The enforcement paper trail is only part of the damage. The operational fallout usually arrives first.

Registration is the visible step, but MSB status carries a continuing federal compliance load under the Bank Secrecy Act.

Most registration problems we clean up trace back to the same handful of mistakes. Each one is cheap to avoid and expensive to unwind.

The initial Form 107 starts a lifecycle, not a one-time task. Under 31 CFR 1022.380, the registration covers a two-calendar-year period, and the renewal must be filed by December 31 of the calendar year before each new period, again through BSA E-Filing and again with no fee.

Three events force a re-registration outside the normal cycle: a change in ownership or control that requires the business to re-register under state law, a transfer of more than 10 percent of the voting power or equity interests (for companies that do not report such transfers to the SEC), and an increase of more than 50 percent in the number of agents during a registration period. The new filing is due within 180 days of the event, and the year it happens becomes year one of a fresh two-year period.

Alongside the registration itself, MSB status carries continuing duties: filing suspicious activity reports and currency transaction reports when thresholds are met, keeping BSA records, maintaining the agent list, and keeping the AML program current as products change. Our /money-transmitter-compliance-officer page covers the role that owns this day to day, and /money-transmitter-license-timeline shows how the federal and state clocks run in parallel.
