Three events that restart the MSB registration clock
The renewal obligation runs on a calendar: every registration period ends on a December 31, and the whole cohort files against the same date. Re-registration is the other clock, and it runs on events. Nothing on a calendar announces it, its deadline is counted in days from something that happened inside your business, and it quietly moves your December 31. The governing text is one paragraph, 31 CFR 1022.380(b)(4), and this page works through it clause by clause (eCFR text read 2026-08-25, current through 2026-08-24).
Trigger one: a change that state law calls a re-registration
The text: “If a money services business registered as such under the laws of any State experiences a change in ownership or control that requires the business to be re-registered under State law, the money services business must also be re-registered under this section.”
The federal rule delegates the trigger’s definition to your state. Whatever ownership or control change your state’s licensing statute treats as requiring re-registration, the federal registration follows it automatically. Which changes those are is a question of the state’s law, varies by state, and is outside what this page can answer from federal sources; what the federal text settles is only the consequence: state re-registration drags the FinCEN registration with it.
Trigger two: more than 10 percent of voting power or equity moves
The text: “if there is a transfer of more than 10 percent of the voting power or equity interests of a money services business (other than a money services business that must report such transfer to the Securities and Exchange Commission), the money services business must be re-registered under this section.”
Two readings worth pinning down. The threshold is “more than 10 percent,” so a transfer of exactly 10 percent sits outside the text. And the parenthetical carves out businesses that must report the transfer to the SEC, which for a small private operator changes nothing: the carve-out exists for issuers with securities-law reporting duties, and the typical single-location registrant has none.
Trigger three: the agent network grows by more than half
The text: “if a money services business experiences a more than 50-per cent increase in the number of its agents during any registration period, the money services business must be re-registered under this section.” The measure is a count of agents, the same count the business already maintains: under 1022.380(d)(1), “A money services business must prepare and maintain a list of its agents,” revised each January 1. An operator whose agent list went from 20 names to 31 inside one registration period has crossed the line, whatever the revenue did.
Note the asymmetry: growth triggers, shrinkage does not. The paragraph names an increase only.
The deadline, and the part everyone misses
The filing window is generous but fixed: “The registration form must be filed not later than 180 days after such change in ownership, transfer of voting power or equity interests, or increase in agents.”
Then comes the sentence that moves your calendar: “The calendar year in which the change, transfer, or increase occurs is treated as the first year of a new two-year registration period.”
Worked through with dates. Suppose your current registration runs the 2025 to 2026 period, renewal due 2026-12-31, alongside the 9,690 registrants our extraction of the public register counted in that cohort on 2026-08-21. On 2026-03-10 a partner buys 15 percent of the equity. Three things follow from the texts above: the transfer crosses “more than 10 percent,” so re-registration is required; the form is due not later than 2026-09-06, 180 days on; and 2026 becomes year one of a new period running 2026 to 2027, which under the renewal rule of 1022.380(b)(3) puts your next renewal filing at 2027-12-31. Your original 2026-12-31 renewal date no longer exists. The event replaced it.
This is why an MSB’s renewal date cannot be assumed stable from one cycle to the next, and why a computed date from the public register is a starting point rather than an answer. The lookup at msbrenew.com/check shows the filing FinCEN’s register currently carries for your business and the December 31 it computes to; whether an event since then has restarted your clock is something only your cap table and agent list can say.
Filing it: the same form, a different box
Re-registration is not a separate form. FinCEN’s RMSB Electronic Filing Instructions (July 2014, retrieved 2026-08-25) put all four gestures on Part I of the same RMSB: initial registration, renewal, correction, and re-registration are checkboxes, and for a re-registration the instructions add: “If you checked box 1d, please indicate the reason by checking boxes 2a, 2b, or 2c (check all that apply),” the three reasons being the three triggers above.
Keep re-registration distinct from a correction in your head as well as on the form. The instructions route ordinary fixes through “Correct/amend a prior report,” a refiled RMSB with the correction box checked. A corrected address or a new trade name amends the record and moves no dates. A re-registration answers a triggering event and resets the period. The easy failure is filing the cheap one when the expensive one was due.
What the paragraph does not reach
The three triggers are the paragraph’s whole list, and each is quoted above in full. Growth in transaction volume, new activity lines, a moved office, an added branch: none of these appears in (b)(4). A branch, in particular, never files its own registration at all, per 1022.380(b)(1)(ii): “A branch office of a money services business is not required to file its own registration form.” Such changes belong on the next filing, or in a correction, under the instructions’ amendment route. Whether they carry obligations under your state’s licensing law is, once again, a state question, and this page stops at the federal text.
