Who needs a money transmitter license?
If your business receives money from one person and moves it, holds it, or converts it for another, you are probably a money transmitter in the eyes of US regulators. This page explains who needs a Money Transmitter License (MTL), who is exempt, and how the state and federal layers fit together.
The Legal Definition, In Plain English
Federal law (31 CFR 1010.100(ff)(5)) defines money transmission as accepting currency, funds, or value that substitutes for currency from one person and transmitting it to another person or location, by any means. Each state has its own version of this definition in its money transmission statute, and most states have now aligned their language under the Money Transmission Modernization Act (MTMA), a model law adopted by a majority of states since 2021.
The key phrase is "on behalf of others." Moving your own money is not money transmission. Moving, holding, or converting someone else's money is.
Activities That Require an MTL
1. Money Transfer and Remittance
Transferring funds between individuals or businesses, domestically or internationally
Operating a remittance business that sends money overseas
Payout and disbursement services where you receive funds and forward them to a beneficiary
2. Currency Exchange Involving Custody
Exchanging fiat currencies (for example, USD to EUR) when you take possession of customer funds
Exchanging digital assets for fiat (for example, USDT to USD) while holding customer funds at any point in the flow
Pure over-the-counter currency exchange with no transmission leg is treated differently in some states, but the moment you hold funds and deliver value to a third party or a different location, you are transmitting.
3. Issuing or Selling Payment Instruments and Stored Value
Selling or issuing money orders, traveler's checks, or prepaid access
Issuing stored-value or closed-loop products that can be redeemed for cash or used with third-party merchants
4. Digital Wallets and Payment Apps
Holding customer balances in an app or wallet
Facilitating peer-to-peer payments, bill pay, or merchant payouts where funds pass through your accounts
5. Virtual Currency Activity
Exchanging, transferring, or custodying cryptocurrency on behalf of customers
Operating crypto ATMs or kiosks
Running an exchange or brokerage that holds customer fiat or crypto
State treatment of crypto is not uniform. New York requires a BitLicense or limited-purpose trust charter. States such as Washington, Alaska, and Florida bring virtual currency squarely into their money transmission statutes. A smaller group has exemptions or no clear position. FinCEN, however, has treated convertible virtual currency exchangers and administrators as money transmitters since its 2013 guidance, so federal MSB registration applies regardless of your state footprint.
6. Escrow and Marketplace Payment Flows
Holding buyer funds in escrow pending delivery
Collecting payments on a marketplace and settling to sellers, unless a valid exemption applies (see below)
7. Acting as an Authorized Delegate
Acting as an agent or sub-agent of a licensed money transmitter. You do not need your own license, but you must operate under a written agent agreement, and the licensee is responsible for your conduct. This "sheltering" model is a common market entry route, and it only works if the agreement and the flow of funds are structured correctly.
Who Is Generally Exempt
Exemptions vary by state, so treat this list as a starting point, not a conclusion:
Banks and credit unions, including in many states their service providers acting for the bank
Agent of the payee: in roughly half the states, a company collecting payment as the appointed agent of the merchant (the payee) is exempt, because payment to the agent legally counts as payment to the merchant. This is the exemption most marketplaces and payment facilitators rely on, and its scope differs meaningfully state to state
Payment processors operating under the FinCEN payment processor exemption: processing through clearance and settlement systems (such as card networks or ACH) under a formal agreement with the merchant. Note that this is a federal exemption; it does not automatically excuse state licensing
Closed-loop stored value redeemable only with the issuer or its affiliates, in most states
Payroll processors in states that carve them out
A federal exemption never cancels a state obligation, and a state exemption never cancels FinCEN registration. The two layers are analyzed separately.
The Two-Layer System
State licensing. Money transmission is licensed state by state. You need a license in each state where you have customers, not just where your company is incorporated. Applications for most states run through the NMLS (Nationwide Multistate Licensing System). Every state now has a licensing regime, including Montana, historically the lone holdout, which adopted the MTMA and began licensing money transmitters in 2023. Requirements typically include surety bonds, minimum net worth, audited financials, background checks on control persons, and a compliance program. Multistate coverage commonly takes 12 to 24 months and a low-to-mid six-figure budget when you include bonds, capital, legal, and compliance staffing.
Federal registration. Separately, any money services business must register with FinCEN within 180 days of starting operations. Registration is free and fast, but it triggers the real obligations: a written AML program, suspicious activity reporting, currency transaction reporting, recordkeeping, and OFAC sanctions screening. FinCEN registration is not a license and does not authorize you to operate in any state.
What Happens If You Skip Licensing
Federal: operating an unlicensed money transmitting business is a crime under 18 U.S.C. § 1960, punishable by fines and up to five years imprisonment. Prosecutors have used this statute against crypto operators, informal remitters, and payment startups alike
State: cease-and-desist orders, civil penalties per transaction, refund obligations, and in some states criminal referral
Commercial: banks will exit the relationship, processors will terminate, and acquirers will not touch you. Loss of banking access usually kills the business before the regulator does
A Quick Self-Test
Answer these four questions:
Do customer funds ever sit in an account you control, even for minutes?
Do you move value from one party to another party or location?
Do you convert one form of value into another for customers?
Do you issue anything customers can redeem or spend with third parties?
If the answer to any of these is yes, assume you need licensing analysis before you launch, not after.
Key Consideration
The flow of funds decides everything. Not your marketing language, not your terms of service, not what you call yourself. Regulators look at where the money actually sits and who actually controls it. Two companies with identical websites can have opposite licensing outcomes because of one difference in settlement structure.
This page is general information, not legal advice. Licensing outcomes depend on your specific flow of funds and the states involved. Get a qualified analysis before you operate.
