Adding payments to a product can bring a business within the scope of **money transmission laws**, even when moving money is only a small part of what it does. In the United States, understanding those obligations means looking at two layers: federal rules and the laws of each state where the service is offered. This guide explains what money transmission means, why the rules reach beyond remittance companies, how the main exemptions work, and what registration and state licensing involve.

US money transmission: federal rules, state licenses and exemptions.

{% hint style="warning" %} This guide is for information only and is not legal advice. Ask qualified legal counsel how federal and state money transmission rules apply to your particular business model. {% endhint %} ## What is money transmission? In general, money transmission means receiving currency, or value used in place of currency, from one party in order to send it to another. Examples of such substitutes can include **money orders, stored value cards and cryptocurrency**. A money transmitter faces two separate sets of requirements: | Level | Requirement | | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | | Federal | Registration with the Financial Crimes Enforcement Network, or **FinCEN** | | State | A money transmitter license in each state whose residents can use the service, unless an exemption applies; **Montana** is the exception to state licensing | Depending on the business model, the compliance approach may involve an appropriately structured **FBO (for the benefit of) account** with a bank, or obtaining the business's own registrations and licenses. These are different approaches, and choosing between them requires understanding how the money actually moves. ### Why the rules reach fintechs and marketplaces Money transmission laws were originally designed around remittance providers such as **Western Union and MoneyGram**. Today, payments and other financial services are built into many products whose main purpose is something else. The regulations have not kept pace with that change. Their broad wording can reach an online marketplace, bill payment software or a peer-to-peer payment app. Any company adding money movement to its product therefore needs to consider whether the rules apply. For startups serving the whole US market, the difficulty grows: federal and state rules differ, states differ from one another, and those rules do not always pursue the same objectives. Applying them to a new technology or business model can be far from straightforward. ## Primary vs. incidental money transmission A useful starting point is to ask whether moving money is the product itself or a supporting part of another service. | | Primary money transmission | Incidental money transmission | | ---------------------- | ----------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | | Role of money movement | The core business activity | Part of a business whose main activity is something else | | Typical businesses | Payment processors, P2P payment apps and cryptocurrency exchanges | E-commerce businesses and marketplaces that handle payments exclusively to enable the delivery of goods or services sold through their platforms | | Examples | Square, Venmo and Coinbase | Etsy, Airbnb and Uber | These categories help explain the business models, but the boundary is not always clear. The details of a company's operations determine which description fits. Moving money only incidentally does not, by itself, put a business outside the rules. ## Federal money transmission rules: the BSA and FinCEN At the federal level, the **Bank Secrecy Act (BSA) of 1970** provides the framework, and FinCEN enforces compliance. Under [FinCEN's definition](https://www.ecfr.gov/current/title-31/subtitle-B/chapter-X/part-1010/subpart-A/section-1010.100), money transmission involves accepting currency, funds or value that substitutes for currency from one person and transmitting it to another person or location, by any means. The BSA aims to prevent **money laundering and terrorist financing** by requiring transactions to be traceable and attributable to known parties. ### Where money services businesses fit Money transmitters belong to the broader category of **money services businesses (MSBs)**. The category also covers currency exchangers and issuers of money orders, stored value cards and traveler's checks. The source overview distinguishes these businesses from banks, regulated financial institutions and entities regulated by the Securities and Exchange Commission (SEC) or the Commodity Futures Trading Commission (CFTC). It describes those institutions as outside the MSB category and exempt from registering with FinCEN as money transmitters, even when they move money. Any other business in the flow of funds may be treated as a money transmitter and required to register, whether transmission is primary or incidental. FinCEN's guidance has, however, established exemptions for particular business arrangements. ## Three common money transmitter exemptions The original overview describes three common exemptions from **federal money transmitter registration**: **payment processor**, **agent of the payee** and **authorized delegate**. Each depends on the arrangement through which the business handles payments. ### 1. Payment processor exemption This route applies to companies whose primary activity is processing payments. The key elements are: * **A regulated payment network**, such as ACH or Fedwire. Participation in these networks is restricted to institutions, such as banks, that are already subject to the BSA. The exemption described in the source allows processors to handle payments through those partners without obtaining their own money transmitter license for that arrangement. * **A formal agreement with the seller or merchant** authorizing the processor to collect payments on its behalf for the goods or services it provides. Examples include **Square, Braintree and the bill aggregator Bill.com** when they process merchants' ACH payments through partnerships with banks or other financial institutions. ### 2. Agent of the payee exemption An agent of the payee collects payments on behalf of a business supplying goods or services. Like the payment processor arrangement, it requires a **formal agreement with the payee** covering payment handling. These businesses generally fall into the incidental transmission category. **Uber and Airbnb** illustrate the model: Airbnb collects a guest's payment exclusively to pass it to the host through a regulated network such as ACH. ### 3. Authorized delegate exemption Under the authorized delegate arrangement, a company moves funds without registering separately as a money transmitter by working with a partner that already holds a money transmitter license or is exempt from money transmitter registration. The most common setup described in the original overview is a company handling payments through an **FBO account at its partner bank**, operating under that bank's money transmission exemption. Consider a startup that runs a **construction equipment rental marketplace**. Its business is connecting renters with equipment owners. The FBO account would be used only to facilitate payments between those two groups. ### Comparing the three arrangements | Arrangement | Who it serves | Key feature | | ------------------- | ----------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- | | Payment processor | Businesses primarily processing payments | Regulated networks such as ACH or Fedwire, a bank or financial institution partner, and a formal merchant agreement | | Agent of the payee | Businesses collecting payments for a provider of goods or services, generally incidentally | A formal agreement with the payee to handle payments | | Authorized delegate | Businesses moving money through a partner licensed as a money transmitter or exempt from money transmitter registration | Reliance on the partner's status; the bank example uses an FBO account | {% hint style="info" %} Whether an exemption fits depends on the details of your business model. Have your lawyer assess the arrangement, including the separate requirements in each relevant state. {% endhint %} ## FinCEN MSB registration: timing, cost and ongoing duties A business that cannot use an exemption must register with FinCEN as an MSB. | Registration question | Requirement | | ------------------------------------- | ------------------------------------------------------------- | | When is the initial registration due? | Within **180 days** of starting money transmission operations | | How often is renewal required? | Every **two years** | | What does registration cost? | Registration is **free** | | How is it submitted? | Through FinCEN's online registration system | Registration also brings ongoing compliance responsibilities. Businesses need processes for **suspicious activity reporting**; the source emphasizes bringing suspect transactions to FinCEN's attention immediately. They must also maintain an **agent list** covering other entities that resell or distribute their money transmission services. Although the online registration process is relatively straightforward, qualified legal counsel should still be involved. ## State money transmitter licensing State rules are often the most difficult part of a money transmission compliance strategy. They differ from federal requirements and can vary substantially from one state to the next. **A business must comply in every state whose residents use its service, regardless of where it is headquartered.** The source describes state obligations as applying as soon as a business offers its product or service to an individual or company resident in that state. A company serving customers across the country therefore has to meet the requirements in each relevant state. ### Why the requirements differ Federal regulation mainly focuses on preventing money laundering. State laws are harder to explain through a single objective. Their priorities can include consumer protection, preventing money laundering and attracting financial services businesses. Three states illustrate the different approaches: | State | Regulatory approach | | ---------- | ---------------------------------------------------------------------------------------------------------------------------------- | | California | Protect customers of money transmission businesses and maintain public confidence in financial institutions operating in the state | | New York | Support the growth of the financial industry and eliminate financial fraud | | Montana | No state money transmission regulations of its own | Those different priorities help explain why the rules do not follow a uniform structure. ### A federal exemption does not settle the state question Exemptions are not consistently available across states. The original **2021 overview** gives these examples: * **Agent of the payee:** Illinois and Florida did not appear to offer this exemption, while California introduced it in **2014**. * **Authorized delegate:** the source described this exemption as apparently available only in **Texas and New York**. * **Qualifying conditions:** even where states recognize the same exemption, they can impose very different requirements. These are the source's historical examples, rather than a current state-by-state checklist. The inconsistency is especially difficult for incidental transmitters. Separate licenses across states may make commercial sense for **Coinbase, Square**, or a startup whose core business is money movement. For the construction equipment rental marketplace, obtaining those licenses may be completely unfeasible when payments are only a supporting part of the service. ### Standardization efforts: MTRA, UMSA and NMLS The source describes a slow effort to bring state regulations and exemptions into closer alignment. It highlights the **Money Transmitter Regulators Association (MTRA)** and the **Uniform Money Services Act (UMSA)**, a model law intended to give states a common template. At the time of the overview, the source reported that only **seven states had enacted the UMSA: Alaska, Arkansas, Iowa, New Mexico, Texas, Vermont and Washington**, along with **two territories: Puerto Rico and the US Virgin Islands**. That list is retained here as part of the source's historical account. The **Nationwide Multistate Licensing System (NMLS)** serves a different purpose. Established in **2008**, it gives businesses a shared system for applying for, amending, renewing and surrendering state licenses, including money transmission licenses, across multiple states. **NMLS does not write state law or grant licenses.** It supports information sharing and coordination between businesses and state regulators to make the multistate licensing process easier to manage. ## Why US money transmission laws are difficult to navigate Many of these rules were not designed for consumers seeking faster, cheaper and more accessible financial services. That mismatch is a major reason compliance becomes complicated when a new product starts moving money. In the decade leading up to the original overview, the growth of fintechs such as **Stripe, Square and Coinbase** encouraged regulators to clarify licensing requirements and explain exemptions more precisely. Understanding the federal framework, state differences and the role of bank arrangements gives you a starting point for discussing compliance with your **legal counsel, bank partners, customers and other stakeholders**. ## Frequently asked questions ### Can a marketplace be a money transmitter? Yes. Money transmission rules can reach marketplaces that collect money from one party and pass it to another, even when payments are incidental to the main service. Whether an exemption applies depends on the payment arrangement and the relevant federal and state rules. ### What is the difference between FinCEN registration and state licensing? FinCEN registration is the federal MSB requirement. State licensing is a separate question for each state whose residents can use the service. Meeting one set of requirements does not resolve the other. ### What does the payment processor exemption require? The arrangement described above uses regulated payment networks, such as ACH or Fedwire, through a bank or financial institution partner. The processor must also have a formal agreement with the merchant to collect payment for its goods or services. ### How does an FBO account relate to money transmission? The source describes an appropriately structured FBO account as a way to handle certain payments through a bank partner's exemption. Its example is a rental marketplace using the account exclusively for payments from renters to equipment owners. The details of the arrangement determine whether it fits the business's compliance needs. ### When must a money transmitter register with FinCEN? A business that needs to register must do so within 180 days of starting money transmission operations and renew every two years. The online registration is free, with ongoing responsibilities including suspicious activity reporting and maintaining an agent list. ### Does NMLS issue money transmitter licenses? No. NMLS is a shared system for managing applications and other licensing tasks. State regulators grant the licenses. *** *Source:* [*Modern Treasury's overview of US money transmission laws*](https://www.moderntreasury.com/journal/how-do-money-transmission-laws-work)*, published September 28, 2021.
