Online Gambling Laws: Where Online Gambling Is Legal
What Federal Online Gambling Laws Actually Cover
Online gambling laws decide who can bet real money online and which companies may take those bets. In the U.S., the answer depends on where the player’s phone is at that moment. Drive from Newark into Manhattan, and it changes mid-trip. New Jersey licenses online casino gaming. New York, for all its size, still doesn’t.
The legal map is lopsided. Sports betting got the green light quickly after 2018 and is now legal in 39 states plus D.C., most of them with mobile apps. Online casinos moved far slower. Only eight states have said yes, and Maine hasn’t switched its market on yet. Money has followed the few states currently licensing it. The seven live online casino states pulled in $10.73 billion in 2025, per the American Gaming Association. In Pennsylvania and New Jersey, online play has out-earned the physical casino floors, a first for both.
There’s no federal law that makes online gambling legal. There’s no nationwide ban across all 50 states either. Washington’s role is narrower, covering interstate transmission and payment flows.
The Wire Act, then and now
Robert Kennedy’s Justice Department pushed the Wire Act through in 1961 to cut off mob bookmakers who took sports bets by phone. For years the Department of Justice read it more broadly. Its position kept shifting. A 2011 opinion said the Act only reached sports betting, and a 2018 opinion said it reached everything. New Hampshire’s lottery sued, and in 2021 the First Circuit sided with the narrow reading. Because of that case, a state can license online casinos or pool poker players with other states without federal exposure.
UIGEA and the payment side
The Unlawful Internet Gambling Enforcement Act of 2006 never touches the player. It goes after the money instead. If a bank or card processor knowingly pushes deposits to a site that breaks federal or state law where the bet is placed or received, the bank is the one exposed. One carve-out matters a lot. Bets placed and accepted inside a single state that has chosen to regulate online gambling don’t count, and every state online casino market is built on that exemption.
Which Online Gambling States Allow What
| Legal status | States |
|---|---|
| Online casino gaming legal and live | Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, West Virginia |
| Online casino legalization passed, launch pending | Maine |
| Online poker only | Nevada |
| Online sports betting but no online casino | More than 20 states, including New York, Illinois, Ohio, and Arizona |
| No legal online gambling | Several states, including California, Texas, and Utah |
Most states moved to legalize sports betting first after 2018. Online casinos got a colder reception. Lawmakers in New York, Illinois, and elsewhere keep hearing the same objection, that iGaming could eat into commercial casino revenue and state lotteries, and bills to legalize online casino play keep stalling on it.
Interstate gambling only really exists for online poker. Nevada, New Jersey, Michigan, and a few other states share player pools through a multi-state compact, so their tables don’t go empty at 3 a.m.
New Jersey went first with online casinos back in 2013, and most bills written since then borrow heavily from its rules. Maine is the newest online casino legalization. Its law, which became law in early 2026, reserves the market for the state’s Wabanaki Nations tribes.
How states regulate online casinos
State gambling regulations follow a similar template. Most tie an online license to an existing land-based casino or tribal casino, so a new brand enters the market as a “skin” under a local partner. Players must be 21 and pass identity checks, and geolocation confirms they are inside the state before every session. Operators must offer responsible gambling tools such as deposit limits, time-outs and self-exclusion, and fund problem gambling programs. Tax rates vary sharply. Pennsylvania takes 54% of gross revenue from online slots.
Enforcement against unlicensed sites
Enforcement has grown in scale. The Michigan Gaming Control Board issued cease-and-desist orders to 45 offshore operators over four months ending in April 2026. Its executive director put the message bluntly.
“follow the law or we will stop you”

How Other Jurisdictions Regulate Online Gambling
Outside the U.S., online gambling laws fall into four broad approaches.
| Approach | How it works | Example |
|---|---|---|
| National license | One federal regulator licenses sports betting and online casinos for the whole country | Brazil, since January 2025 |
| Point-of-consumption license | Any operator serving local players needs a local license, wherever it is based | United Kingdom |
| Provincial or state licensing | Each region licenses separately | Argentina, Canada (Ontario), U.S. states |
| Export license | A small jurisdiction licenses operators to serve markets that have not regulated online gaming | Curaçao, under its 2024 LOK framework |
The export model has limits. A Curaçao license gives no legal standing in Brazil, the UK or any U.S. state, since each of those markets demands its own license and blocks unlicensed domains and payments. Brazil, for example, requires licensed operators to use .bet.br domains and bans credit card and crypto deposits.
Argentina shows the provincial model in practice. Buenos Aires City and Buenos Aires Province license online operators separately, and a brand approved by one cannot legally accept players located in the other.
Planning a Launch Around Online Gambling Laws
Operators planning a market entry should check the legal status of each product separately. Online sports betting and online casino games are often licensed under different statutes, and a market can open one years before the other. Local payment rules and data hosting requirements also affect the technical build, often more than the license terms themselves.
Getting licensed remains the operator’s job, market by market, and a software supplier cannot replace that step. BSW supplies the technology side, a custom platform with casino and sportsbook modules, local payment systems, and configurable limits, adapted to the rules of each target market on a project-by-project basis.
FAQ
What is considered unlawful internet gambling?
Under UIGEA, unlawful internet gambling is placing, receiving, or transmitting a bet over the internet when that bet is illegal under federal or state law where it is initiated or received. Playing at a site without a license from your state usually meets that definition.
What happens if you get caught gambling illegally online?
Individual players are rarely prosecuted, but they can lose deposits and winnings with no regulator to appeal to. A few states, including Washington, treat online gambling as a crime. Operators face cease-and-desist orders, fines, blocked payments, and criminal charges.
Are online casino winnings taxed, and does it vary by state?
Yes. The IRS treats all gambling winnings as taxable income, and large wins trigger a W-2G form from the operator. State income tax on winnings varies, and players in states without a personal income tax owe federal tax only.
Which states have legalized online casinos?
Eight states. New Jersey came first in 2013, followed by Delaware, Pennsylvania, Michigan, West Virginia, Connecticut, and Rhode Island. Maine legalized online casinos in 2026 and has not launched.
How can I tell if an online casino is legal and licensed?
Look for the state regulator’s name and license number on the site, then confirm it on the regulator’s published list. Licensed apps require location checks and identity verification. Offers aimed at players in every state are a warning sign.
