The United States maintains one of the most comprehensive regulatory frameworks for financial services — and with the rise of digital assets, compliance has become more critical than ever. For companies operating in the cryptocurrency space, securing the appropriate licenses is not optional — it's a legal necessity. Among the most essential is the Money Services Business (MSB) license, regulated at the federal level by the Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Department of the Treasury.
This guide breaks down everything crypto businesses need to know about the MSB license: what it is, who needs it, how to register, and what compliance obligations follow.
What Is a U.S. Money Services Business (MSB)?
The U.S. Money Services Business (MSB) license is a federal registration requirement for entities engaged in certain financial activities involving money transmission, exchange, or prepaid access. While often referred to as a "license," it is technically a registration with FinCEN under the Bank Secrecy Act (BSA).
Any business that operates as an MSB is legally considered a financial institution, which brings with it strict anti-money laundering (AML), customer identification (KYC), reporting, and recordkeeping responsibilities.

Who Regulates MSBs?
- Regulator: Financial Crimes Enforcement Network (FinCEN)
- Parent Agency: U.S. Department of the Treasury
- Governing Law: Bank Secrecy Act (BSA)
It’s important to note that MSB registration does not replace state-level requirements. Most crypto firms must also obtain a Money Transmitter License (MTL) from each state where they operate — a separate, often complex process.
Defining a Money Services Business: 8 Key Categories
Under U.S. law, any person or entity conducting one or more of the following activities in the U.S. may be classified as an MSB:
1. Foreign Exchange Dealer
An individual or company that exchanges currency — domestic or foreign — on behalf of others, where the total value exceeds $1,000 in a single day.
2. Check Casher
Anyone who cashes checks or monetary instruments for more than $1,000 in one or more transactions per day. Exemptions include merchants accepting checks for goods/services or employers cashing employee payroll checks.
3. Issuer or Seller of Traveler’s Checks or Money Orders
Entities that issue or sell traveler’s checks or money orders exceeding $1,000 in a single day.
4. Prepaid Access Provider
A business that issues or controls prepaid access programs (e.g., gift cards, digital wallets). This category is highly relevant to crypto platforms offering custodial wallets or payment solutions.
Note: Closed-loop systems (e.g., store-specific gift cards) with limits under $2,000 per day may be exempt.
5. Money Transmitter
This is the most relevant category for crypto companies. A money transmitter accepts funds or value from one party and transmits it to another — whether through banks, digital networks, or informal systems.
This includes:
- Crypto-to-fiat exchanges
- Peer-to-peer (P2P) trading platforms
- Wallet services enabling fund transfers
- Stablecoin issuers facilitating transfers
Exemptions apply to payment processors acting on behalf of merchants and clearinghouse operators.
6. U.S. Postal Service
The USPS qualifies as an MSB but is largely exempt from certain reporting rules when selling postage or philatelic products.
7. Seller of Prepaid Access
Selling prepaid access worth over $10,000 in a single day without proper KYC procedures triggers MSB classification.
8. Exceptions: Who Is Not an MSB?
- Banks and federally insured credit unions
- SEC- or CFTC-registered entities
- Individuals occasionally exchanging small amounts without profit motive
How to Register as an MSB with FinCEN
All MSBs must register electronically via the BSA E-Filing System using FinCEN Form 107.
Key Registration Requirements
- Deadline: Must register within 180 days of starting business operations.
- Responsible Party: The owner or controlling person must submit and sign the form.
- Renewal: Registration must be renewed every 24 months, by December 31st of the second year.

Required Information on Form 107
- Legal business name and physical address
- Names and addresses of owners, directors, and senior managers
- U.S.-based bank account used for business transactions
- Estimated annual transaction volume
- List of agents (if applicable)
Branches do not need separate registration, but must be listed in the parent entity’s filing.
When Is Re-Registration Required?
Even after initial registration, certain events trigger a re-registration requirement:
- Change in ownership or control (e.g., sale, merger)
- Transfer of voting shares exceeding 10%
- Agent network grows by more than 50%
Re-registration must be completed within 180 days of the triggering event.
Maintaining an Agent List: A Critical Compliance Duty
If your MSB uses third-party agents (e.g., retail partners selling gift cards or enabling cash-in/cash-out), you must:
- Maintain a detailed list of all agents
- Update the list annually by January 1
- Retain records for five years
- Provide the list to FinCEN upon request
Each agent entry must include:
- Name and address
- Services offered (e.g., money transmission, check cashing)
- Transaction volume (if over $100,000/month)
- Associated bank accounts
Post-Registration Compliance Obligations
Registering as an MSB is just the beginning. Ongoing compliance is mandatory and rigorously enforced.
1. Implement an Anti-Money Laundering (AML) Program
Every MSB must establish a written AML program within 90 days of registration. The program must include:
- Internal policies and procedures for detecting suspicious activity
- Designation of a compliance officer
- Employee training on AML/KYC protocols
- Independent audit function to test effectiveness
The program must be risk-based — tailored to your business size, geography, and services offered.
2. File Suspicious Activity Reports (SARs)
MSBs must file a SAR when they detect a transaction that:
- Exceeds $2,000
- Appears suspicious or lacks legitimate purpose
- Involves potential money laundering or fraud
Suspicious behavior includes:
- Structuring transactions to avoid reporting thresholds
- Use of fake IDs or inconsistent customer information
- Rapid movement of funds across accounts with no clear purpose
SARs must be filed within 30 calendar days of initial detection.
3. Submit Currency Transaction Reports (CTRs)
Any transaction involving more than $10,000 in cash must be reported using a CTR. This includes:
- Deposits
- Withdrawals
- Currency exchanges
CTRs help track large cash movements and deter illicit financial activity.
4. Keep Detailed Records
MSBs must retain records for at least five years, including:
- Transaction logs
- Customer identification data
- SARs and CTRs
- AML program documentation
- Agent lists
For prepaid access providers, identity verification records must be kept for five years after last use.
Why This Matters for Crypto Businesses
With increasing scrutiny on digital asset platforms, many crypto exchanges, wallet providers, and DeFi-related services fall under the money transmitter definition. Failure to register can result in:
- Heavy fines
- Criminal charges
- Shutdown orders
- Reputational damage
Proactive compliance isn’t just about avoiding penalties — it builds trust with users, partners, and regulators.

Frequently Asked Questions (FAQs)
Q: Do I need an MSB license if I only deal in cryptocurrency?
A: Yes. If your business involves transmitting or exchanging digital assets as a service — especially when converting between crypto and fiat — you likely qualify as a money transmitter and must register with FinCEN.
Q: Is an MSB registration the same as a state money transmitter license?
A: No. MSB registration is federal and handled by FinCEN. State MTLs are issued individually by each state’s financial regulator and often require net worth minimums, bonding, and on-site audits.
Q: Can a foreign company register as an MSB?
A: Yes, but you must appoint a registered agent with a physical address in the U.S. who can receive legal notices on your behalf.
Q: What happens if I don’t register as an MSB?
A: Penalties include fines up to $500,000 per violation and up to 10 years in prison under the Bank Secrecy Act.
Q: How long does MSB registration take?
A: The electronic filing process typically takes a few days, but preparing documentation — including AML policies and agent lists — can take weeks.
Q: Does having an MSB license allow me to operate nationwide?
A: Not automatically. You still need state-by-state approvals for money transmission. The MSB registration is just the federal baseline.
Final Thoughts
Navigating the U.S. regulatory landscape for crypto businesses is complex but essential. The MSB registration is a foundational step — one that signals legitimacy, enables banking relationships, and opens doors to broader market access.
