Commercial casinos in the United States are licensed and regulated primarily at the state level. Tribal casinos operate under a separate federal framework created by the Indian Gaming Regulatory Act (IGRA) of 1988, which involves tribal governments, state compacts, and the National Indian Gaming Commission (NIGC).
There is no national casino license. Instead, a casino must satisfy the regulators in each jurisdiction where it operates, whether that means a state gaming control board, a tribal gaming commission, or both. Federal laws such as the Wire Act and the Unlawful Internet Gambling Enforcement Act (UIGEA) place additional limits on how gaming can be conducted and paid for.
Who regulates casinos in the United States?
The exact name and structure of the regulatory body vary by state. Nevada has the Nevada Gaming Control Board and Nevada Gaming Commission, New Jersey has the Division of Gaming Enforcement within the attorney general's office, and Pennsylvania has the Pennsylvania Gaming Control Board. Other states with commercial or riverboat casinos have similar agencies with investigative, licensing, and enforcement powers.
For tribal gaming, each federally recognized tribe may establish its own gaming commission, but the NIGC serves as the federal regulator. The NIGC reviews tribal gaming ordinances, monitors compliance, and can take enforcement action under IGRA. The U.S. Department of the Interior also plays a role in approving tribal-state compacts.
Other federal agencies touch casino regulation indirectly. The Financial Crimes Enforcement Network (FinCEN) applies Bank Secrecy Act requirements to casinos, treating them as financial institutions for anti-money-laundering purposes. The Internal Revenue Service handles federal tax obligations related to gaming.
| Regulator | Typical role | Examples of authority |
|---|---|---|
| State gaming control board or commission | Licenses commercial casinos, audits operations, enforces state gaming laws | Approving games, investigating applicants, collecting gaming taxes |
| Tribal gaming commission or regulatory agency | Regulates gaming on tribal lands under tribal law and IGRA | Issuing tribal licenses, monitoring Class II and III gaming, ensuring compliance with compacts |
| National Indian Gaming Commission (NIGC) | Federal regulator for tribal gaming | Overseeing Class II gaming, reviewing tribal ordinances, enforcing IGRA |
| State lottery or sports wagering division | May regulate sports betting or online gaming where authorized | Licensing online operators, enforcing geolocation and responsible gaming rules |
How does the Indian Gaming Regulatory Act work?
The Indian Gaming Regulatory Act, passed in 1988, created a three-class system for gaming on tribal lands. Class I covers traditional or social games with minimal prizes and is regulated solely by tribes. Class II includes bingo and certain non-banked card games, and is regulated by tribes with NIGC oversight. Class III includes casino-style games such as slot machines, house-banked table games, and sports betting where authorized, and requires a compact between the tribe and the state.
A Class III compact is a negotiated agreement that addresses how gaming will be conducted, how disputes will be resolved, and often includes provisions for regulation, revenue sharing to offset local impacts, and responsible gambling standards. The compact must be approved by the Secretary of the Interior.
States cannot impose their general regulatory jurisdiction on tribal lands unless a compact grants them a limited role. This is why tribal gaming is often described as a dual federal-tribal system with state involvement only through compact negotiation. Understanding these agreements is part of broader casino policy; see the policy section. The National Indian Gaming Commission publishes guidance on Class II and Class III distinctions.
How does state licensing and approval work for commercial casinos?
Commercial casino licensing is an intensive process. It generally begins with a state law authorizing casino gaming and designating a regulator. Applicants must submit detailed personal and financial information for owners, directors, and key employees. Investigators look for criminal history, hidden ownership, and questionable source of funds.
Background investigations and suitability
Local approval is often required as well. Host cities or counties may hold public hearings, negotiate development agreements, and impose conditions related to traffic, public safety, and infrastructure. The regulatory agency then decides whether to grant a license, sometimes after a competitive bidding process if the state limits the number of licenses.
A typical path includes the following steps:
- State statute or constitutional amendment authorizes casino gaming and establishes a regulatory body.
- Operator submits an application with extensive disclosures about ownership, finances, and proposed operations.
- Regulator conducts background investigations of all key individuals and business entities.
- Local government reviews the proposal and may require impact studies or public hearings.
- Regulator grants a license with conditions such as minimum capital, security plans, and responsible gambling programs.
- License is renewed on a regular schedule, subject to audits and continuing suitability.
The same suitability standards often apply when an existing operator plans a new property or expansion; see our guide to what drives casino expansion projects.
What federal laws affect casino regulation?
Although there is no federal casino license, several federal statutes shape casino operations. The Wire Act of 1961 makes it a federal crime to use interstate wire communications to transmit bets or wagers, and its modern scope has been the subject of federal litigation and shifting Justice Department opinions. The Unlawful Internet Gambling Enforcement Act of 2006 does not make online gambling itself illegal, but it prohibits gambling businesses from knowingly accepting payments connected to unlawful internet gambling.
Casinos are also subject to the Bank Secrecy Act because they handle large volumes of cash. They must file currency transaction reports for certain cash transactions and suspicious activity reports when they detect potential money laundering or other financial crimes. FinCEN oversees these requirements, and state regulators often coordinate with federal agencies on enforcement.
For readers who want to see the text of these laws, the Cornell Legal Information Institute maintains the federal Wire Act statute and related provisions.
How are online casino and sports betting regulated differently?
In 2018, the U.S. Supreme Court struck down the Professional and Amateur Sports Protection Act in Murphy v. NCAA, clearing the way for states to legalize sports betting. Today each state decides whether to authorize sports betting, who may offer it, and how it is taxed. Many states have chosen to regulate sports betting under the same agency that oversees casinos.
Online casino gaming is also state-regulated, but it is legal only in a minority of states. Each state that authorizes online casino games sets its own licensing standards, geolocation requirements to confirm a player is physically inside the state, and responsible gambling rules. The Wire Act and UIGEA still affect interstate payment processing and communications for online wagering.
Geolocation and platform integrity rely on technology that is also used in broader casino operations; see the technology powering modern casinos for more.
What happens after a casino is approved? Compliance and enforcement
Approval is only the beginning. A licensed casino must operate under detailed internal controls, maintain surveillance and security systems, submit to regular audits, and remit gaming taxes. Employees who work in sensitive positions may need their own individual licenses. Independent testing laboratories often certify that games and random number generators operate fairly.
Regulators conduct inspections and may issue citations, impose fines, require corrective action, suspend operations, or revoke a license for serious violations. Financial reporting is a key part of this oversight; a casino's public filings can reveal revenue, expenses, and compliance risks, as explained in understanding a casino company's financial report.
Responsible gambling is also part of compliance. Casinos typically must post information about problem gambling resources and offer self-exclusion programs. The national problem-gambling helpline is 1-800-GAMBLER, and the National Council on Problem Gambling maintains additional resources.
How to check a casino's regulatory status
Most state gaming regulators publish lists of licensed casinos, licensees, and enforcement actions on their websites. For tribal gaming, the NIGC and individual tribal gaming commissions often provide similar information. Public records requests may be an option for documents that are not posted online.
Before traveling to a casino or participating in online gaming, you can verify that the operator holds a valid license in that state. State gaming agency sites typically explain how to file a complaint or report a concern. Regulators and local officials often look at economic impacts before approving a new property, as discussed in the role of casinos in local economies.
The bottom line for casino oversight
Casino regulation in the United States is deliberately decentralized. State governments, tribal governments, and federal agencies each hold only part of the authority, and no single agency licenses every casino. That structure can make the rules look complicated, but it also allows states and tribes to tailor regulation to local conditions.
For anyone studying the industry, the key question is not simply whether a casino is legal, but which regulator oversees it and what conditions apply. That information is usually public, and it shapes everything from expansion plans to financial reporting to the technology a casino may deploy.
