Federal MSB Registration: Form 107 Guide for Crypto Firms

If you own or control a money services business (MSB), federal registration is generally your responsibility. With few exceptions, each MSB must register with the Department of the Treasury, and the owner or controlling person must file FinCEN Form 107, Registration of Money Services Business, within 180 days after the business is established.

That is the core rule. The rest of this guide breaks down how it applies to a crypto business, who signs, when renewal is due, what records to keep, and where the public guidance is silent.

Who has to register

Registration is the responsibility of the owner or controlling person of the MSB, and it must be filed by the registration deadline. If more than one person owns or controls the business, those persons may enter into an agreement designating one of them to register.

That designation does not shift liability. If the designated person fails to register, the other owners or controllers are still liable for the failure to register. A "person" here is broad: it includes an individual, corporation, partnership, trust or estate, joint stock company, association, syndicate, joint venture, or other unincorporated organization or group, an Indian Tribe, and all entities recognized as legal personalities.

There is one important carve-out. A person that is an MSB solely because that person serves as an agent of another MSB is not required to register. This matters for crypto businesses that operate as agents for another registered provider rather than as an independent money transmitter.

The registration form and deadline

The form is FinCEN Form 107, Registration of Money Services Business. It must be completed and signed by the owner or controlling person and filed within 180 days after the date the MSB is established.

Deadline counting is where new crypto businesses often stumble. The regulation gives a window, not a fixed calendar date. In practice, the establishment date starts the clock, and the filing must land inside the 180-day window.

As an illustration only, suppose a crypto exchange is established on January 1 of a non-leap year. The 180th day falls on June 30 of that year (Calculation: January 1 plus 180 days). That is an illustrative calculation, not a deadline FinCEN publishes, and the actual date depends on the establishment date and how the applicable rules count days.

Renewal and re-registration

Registration is not a one-time event. Registration must be renewed every two years. Re-registration is also required in limited circumstances. Crypto businesses should calendar both the two-year renewal and any event that could trigger re-registration, and should confirm the current trigger list against the regulations rather than relying on memory.

Obligation	Detail from the guidance
Initial filing	FinCEN Form 107, signed by owner or controlling person, within 180 days after the MSB is established
Renewal	Every two years
Re-registration	Required in limited circumstances
Record retention	Copy of filed form and supporting documentation kept at a US location for five years

Recordkeeping

A copy of the filed registration form and other supporting documentation must be retained at a location in the United States for a period of five years. For a crypto business, that means the signed Form 107 and the documentation behind it should live in a US location, not only in a foreign subsidiary's files or a cloud account whose location is unclear.

Filing channel and the 2012 e-filing notice

FinCEN announced electronic filing for MSB registrations. A separate notice, dated February 24, 2012, required electronic filing of most FinCEN reports by July 1, 2012, and institutions were strongly encouraged to begin using the BSA E-Filing System as soon as possible.

Those are announcements about the channel. They do not, by themselves, spell out every detail of how an MSB registration must be submitted today. Before filing, confirm the current submission method and any exceptions through the BSA E-Filing resources and the regulations, rather than treating an announcement headline as a complete procedure.

Penalties and why this matters for crypto firms

Civil and criminal penalties may be imposed for violation of the registration requirement. Crypto exchanges and money transmitters often qualify as MSBs, so a missed Form 107 is not an administrative footnote. It can create direct exposure for the owners and controlling persons, including those who were not the designated filer.

A short pre-filing checklist

• Identify every owner or controlling person and confirm who is responsible for filing.
• If multiple persons are involved, consider a written designation agreement, and confirm that all parties understand liability is not shifted.
• Determine whether the business is an MSB solely as an agent of another MSB, which may remove the registration requirement.
• Set the establishment date and track the 180-day filing window.
• Prepare FinCEN Form 107 for signature by the owner or controlling person.
• Plan for two-year renewal and for limited re-registration triggers.
• Store the filed form and supporting documentation at a US location for five years.
• Confirm the current filing channel before submission.

What the source does not say

The guidance is general and does not replace or supersede the regulations. It does not tell you whether a specific crypto product, token, or business model qualifies as an MSB. It does not list every re-registration trigger, and it does not define the full set of records that count as supporting documentation.

It also does not state that every MSB registration must be filed through a particular electronic system, nor does it provide a single fixed calendar deadline beyond the 180-day window. Businesses should read the underlying regulations and current FinCEN instructions before filing.
