The short answer
- State money transmitter licences. The licence stays with the entity, but acquiring control of a licensee needs regulator approval in most states. The CSBS Money Transmission Modernization Act defines control to include the power to vote at least 25 percent of the voting interests and requires prior approval; thirty-one states had enacted it in full or in part as of September 2026.
- FinCEN MSB registration. If the company is a registered money services business, it must re-register within 180 days when more than 10 percent of its voting power or equity is transferred, when state law requires re-registration after a change of control, or when its agent count grows by more than 50 percent.
- Card-network registrations. ISO and payment facilitator registrations with Visa and Mastercard are made and held by the sponsoring acquirer, not by the ISO or payfac. A change of owner means the acquirer notifies the network; a change of sponsor means re-registration and new underwriting.
- Sponsor bank, processor and gateway agreements. Private contracts, so the rule is whatever the contract says: change-of-control consent, assignment restrictions, exclusivity, minimums, reserves and residual-buyout rights. These, not the regulators, are usually the longest pole.
- ACH. If the company originates ACH as a third-party sender, its ODFI must register it with Nacha within 30 days of the first entry and update the registration within 45 days of any change.
- Canada. A Canadian MSB updates its FINTRAC registration within 30 days of a change in ownership or other registration information. A U.S. buyer of a Canadian business may also face Investment Canada Act notification or review.
- Antitrust. Transactions above the 2026 Hart-Scott-Rodino size-of-transaction threshold of $133.9 million are filed with a 30-day waiting period. Most founder-led payments sales fall below it.
Who approves what
| Approval or notice | Who grants it | Trigger | Clock |
|---|---|---|---|
| Acquisition of control of a money transmitter licensee | State regulator (in MTMA states, through NMLS) | A person or group acquires control, defined to include 25 percent or more of voting interests; some states presume control at 10 percent, rebuttable for passive investors | Prior approval. Virginia: written approval before control is acquired; decision within 60 days of a complete application or deemed approved |
| FinCEN MSB re-registration | FinCEN (FinCEN Form 107) | More than 10 percent of voting power or equity transferred; state-law change-of-control re-registration; agents up more than 50 percent | Within 180 days of the event; renewal every 24 months regardless |
| Visa Third Party Agent and Payment Facilitator registration | The sponsoring acquirer, with Visa | New owner, new sponsor or new agent relationship | Set by the acquirer’s agreement and Visa’s registration program; agents cannot register themselves |
| Mastercard Service Provider registration | The acquirer, with Mastercard | Mastercard Rules require the acquirer to notify Mastercard of a service provider’s change of name or transfer of ownership or control | Set by the Mastercard Rules and the acquirer agreement |
| Sponsor bank, processor, gateway and ISV contracts | The counterparty | Change-of-control, assignment and anti-assignment clauses; exclusivity; minimum volume; early-termination and residual-buyout provisions | Whatever the contract says; often the critical path between signing and closing |
| Nacha third-party sender registration | The ODFI, with Nacha | First ACH entry originated through the ODFI on the sender’s behalf; any later change | 30 days to register; 45 days to update |
| FINTRAC MSB registration (Canada) | FINTRAC | Change in ownership, directors, senior officers or other registration information | Within 30 days; renewal every two years |
| Hart-Scott-Rodino filing (U.S.) | FTC and DOJ | Transaction value above $133.9 million (threshold effective February 17, 2026) | 30-day waiting period after filing |
State money transmitter licences
The first question is whether the company holds licences at all. Many ISOs and payment facilitators rely on payment processor or agent-of-the-payee exemptions that differ state by state; a buyer will want the written exemption analysis, not an assurance.
Where licences exist, the licence does not move. The licensed entity is being sold, and the regulator’s interest is in who will control it. The CSBS model act, now the template in thirty-one states, defines control to include the power to vote at least 25 percent of a licensee’s voting interests and requires a person acquiring control to obtain prior approval. State enactments add detail: Virginia’s Code section 6.2-1936 presumes control at 10 percent of voting interests (rebuttable for passive investors), requires the Commission’s written approval before control is acquired, gives the Commission 60 days from a complete application before the application is deemed approved, and allows the Commission to order divestiture of an interest acquired without approval.
Three practical consequences for a seller:
- The buyer’s ownership chart, not just its name, decides the filing. Private equity buyers with multiple funds and co-investors often have several persons who meet a control or presumption threshold, each of whom may need to be reviewed.
- Approval timelines run per state. A company licensed in many states should plan the signing-to-closing gap around the slowest regulator, and the purchase agreement should say which approvals are closing conditions and what happens if one lags.
- Pre-filing conversations with the lead regulator, started once a buyer is selected, shorten the formal review and surface objections while there is still time to restructure.
FinCEN money services business registration
If the company is a registered MSB, FinCEN’s rule is mechanical. Registration lasts 24 months and must be renewed by December 31 of the renewal year. Separately, an MSB must re-register within 180 days when there has been a change in ownership or control that requires re-registration under state law, when more than 10 percent of its voting power or equity interest has been transferred, or when its number of agents has increased by more than 50 percent. A person who is an MSB solely because it acts as an agent of another MSB is exempt from registration. The buyer will also want five years of supporting documentation, which FinCEN requires MSBs to retain at a U.S. location.
Card-network registrations
Visa registers Third Party Agents, including independent sales organizations and payment facilitators, only through its clients, meaning the issuing and acquiring banks; an agent cannot register itself. Mastercard likewise registers service providers through the acquirer, which remains responsible to the network for the service provider’s conduct, and the Mastercard Rules require the acquirer to notify Mastercard of a service provider’s change of name or transfer of ownership or control.
For a seller that means two scenarios. If the buyer keeps the existing sponsoring acquirer, the acquirer handles the ownership notification and the registration continues. If the buyer brings its own sponsor, the portfolio is re-registered and re-underwritten under the new acquirer: new risk review, new reserve terms, new pricing, and merchant-level re-boarding or assignment depending on the structure. The second path is slower and is the one that most often slips the closing date, so confirm which path the buyer intends before the letter of intent is signed.
Sponsor bank, processor and gateway contracts
The regulators publish their rules. The counterparties do not, which is why these contracts are usually the critical path.
Read every sponsor-bank, processor, gateway, ISV and referral agreement for the same six provisions before the company goes to market: change-of-control consent, assignment and anti-assignment language, exclusivity, minimum volume or revenue commitments, early-termination fees, and residual-buyout or right-of-first-refusal clauses. Sort them into three piles: consent required, notice required, nothing required. The consent pile sets the timetable. Where a sponsor bank has a consent right, approach it early with the buyer’s profile; banks evaluate the buyer’s compliance posture and funding exactly as they underwrote the seller. Residual portability, whether residual streams and merchant contracts transfer on a change of control and on whose consent, is the item a buyer discounts hardest when it is unclear.
ACH origination
If the company originates ACH entries for its customers it is likely a third-party sender under the Nacha Operating Rules. Nacha requires each ODFI to register its third-party senders, including nested senders operating through another third-party sender, within 30 days of transmitting the first entry on their behalf, and to update a registration within 45 days of any change. A change of ownership is a change the ODFI will expect to be told about, and a new ODFI relationship means a new registration.
Cross-border: Canada
A Canadian money services business must keep its FINTRAC registration current: changes to registration information, including ownership, are reported within 30 days, and the registration is renewed every two years. A U.S. buyer of a Canadian payments company may also trigger Investment Canada Act notification or review, and Canadian share-sale structuring affects the founder’s after-tax proceeds; both are covered in the firm’s guide to selling to a U.S. buyer.
Antitrust
U.S. transactions valued above the Hart-Scott-Rodino size-of-transaction threshold, $133.9 million for filings from February 17, 2026, require a premerger filing and a 30-day waiting period before closing. Most founder-led payments sales fall below the threshold, but acquisitions by scaled consolidators of several businesses in sequence can approach it. See the firm’s note on the Hart-Scott-Rodino Act.
Sequencing the approvals inside the sale
- Before launch. Build the approvals map: every licence, registration and contract with its trigger, approver and clock. Obtain the written exemption analyses. Fix anything that will not survive a regulator’s or sponsor’s review of a new owner.
- At indications of interest. Ask each bidder which approvals its ownership will trigger and whether it keeps or replaces the sponsoring acquirer. Weigh certainty and speed of close alongside price; a bid that needs no new sponsor and triggers no new state filings is worth more than its headline suggests.
- In the letter of intent. Name the approvals that are closing conditions, who files, who pays, and the long-stop date. Agree how a lagging state approval is handled.
- Between signing and closing. Run the filings in parallel, not in sequence. Keep the sponsor bank informed. Hold back no merchant or processor disclosure a regulator will test.
How the whole sequence fits inside a sale process is set out in how we run a sale; the pricing side is covered in payments valuation benchmarks and the diligence side in the payments due diligence request list.
Questions founders ask
Does a money transmitter licence transfer when the company is sold?
No. The licence stays with the licensed entity, but a change in who controls that entity needs regulator approval in most states. Under the CSBS model act, acquiring control, defined to include the power to vote at least 25 percent of the voting interests, requires prior approval; Virginia requires written approval before control is acquired and can order divestiture if it is not obtained.
Does a FinCEN MSB registration need to be redone after a sale?
If the business is a registered MSB, it re-registers within 180 days when more than 10 percent of voting power or equity has been transferred, when a change in ownership or control requires re-registration under state law, or when its agent count has grown by more than 50 percent.
Can an ISO or payment facilitator registration be transferred to a buyer?
Not by the seller. Visa and Mastercard registrations are made and held by the sponsoring acquirer, which must notify the network of a transfer of ownership or control. A buyer that brings its own sponsor re-registers and re-underwrites the portfolio.
How early should approvals be mapped in a sale process?
Before buyers are approached. The approvals decide which buyers can close quickly, which contracts need consent rather than notice, and how long the signing-to-closing period must be.
