Legality Guide — Online Gambling in the USA

US Online Gambling Regulation — Overview

Online gambling in the USA is legal in many states — but regulated state by state, not by a single federal law. If your state has licensed it and you use a licensed operator, you are playing entirely within the law.

Three federal laws shape the landscape. The UIGEA (2006) does not ban gambling — it restricts payment processors from handling payments for unlawful internet gambling, but explicitly exempts intrastate (within-state) gambling. The Wire Act (1961) was reinterpreted by the DOJ in 2011 to apply only to sports betting, allowing states to license online casinos and poker. And the PASPA repeal (2018) — Murphy v. NCAA — struck down the federal ban on sports betting, opening the door for every state to legalise it independently.

Which states have online gambling?

Online casino gaming is fully legal and live in seven states: New Jersey (since 2013), Delaware (2012), Pennsylvania (2019), West Virginia (2019), Michigan (2021), Connecticut (2021) and Rhode Island (2023). Maine authorized online casino and sports wagering in January 2026 — becoming the 8th state — but its market has not yet launched (expected late 2026 or early 2027). Nevada allows online poker only. Sports betting is legal in 38+ states and Washington DC, with more legalising every year.

Federal gambling tax — what players must know

The IRS treats gambling winnings as taxable income. You must report all winnings on your tax return — there is no minimum threshold. For significant wins, operators are required to withhold 24% automatically and issue a W-2G form. You can deduct gambling losses up to the total of your reported winnings, but only if you itemise deductions. Keep a detailed record of every session — wins and losses — to make filing accurate and defensible.

Geolocation enforcement

Licensed US operators use GPS and IP-based geolocation to verify you are physically inside a legal state before you can play. VPNs do not work — they flag your account and result in winnings being withheld. You must register in your home state, but you can play from any legal state you travel to, as long as you use the right operator for that state.

Legal States — Full Breakdown

Seven states have fully legalised online casino gambling. Sports betting is far more widespread, with 38+ states now on board. Here are the key markets in detail.

New Jersey — The Online Gambling Capital

New Jersey was the first state to fully legalise online casino gaming and poker in 2013, following the DOJ's 2011 Wire Act reinterpretation. It remains the largest and most competitive market in the US, with dozens of licensed operators across casino, poker and sports betting. All operators must be affiliated with one of Atlantic City's nine brick-and-mortar casinos. Regulator: Division of Gaming Enforcement (DGE). Full New Jersey guide →

Pennsylvania — Largest by Revenue

Pennsylvania passed the Gaming Expansion Act in 2017 and went live in 2019. It is now the largest online gambling market in the US by revenue, driven by its 13 million+ population. PA has high operator tax rates (54% on online slots), which means slightly less generous bonuses, but has the broadest operator selection outside of NJ. PokerStars PA dominates the poker market. Regulator: PA Gaming Control Board (PGCB). Full Pennsylvania guide →

Michigan — Fastest Growing

Michigan launched in January 2021 and quickly became one of the most competitive markets in the US. It was the first state to welcome back PokerStars (as Stars Casino), absent since Black Friday in 2011. Michigan's tribal gaming compacts also allow tribal operators to participate digitally. Multi-state liquidity sharing with NJ and other states boosts poker pool sizes. Regulator: Michigan Gaming Control Board (MGCB). Full Michigan guide →

Connecticut, West Virginia, Delaware & Rhode Island

Connecticut (legal 2021) and West Virginia (2019) both offer full online casino, poker and sports betting. Delaware was the very first state to legalise online gambling in 2012, though its small population (~1 million) limits market size — three state-partnered operators share the player pool. Rhode Island joined in 2023 with casino and sports betting (no poker). All four states participate in the Multi-State Internet Gaming Agreement (MSIGA) for shared poker liquidity.

Nevada — Poker Only

Nevada allows online poker but not online casino games. WSOP.com and BetMGM Poker are the main operators. Nevada participates in multi-state poker liquidity sharing with NJ, PA, DE, MI and WV — essential given Nevada's relatively small residential population.

Sports-Betting-Only States

States including New York, Illinois, Colorado, Arizona, Tennessee, Virginia, Ohio, Maryland, Louisiana and Kansas have legalised sports betting without online casino games. New York is the biggest sports betting market in the country by handle, having launched in January 2022. California and Texas — the two most populous states — remain without any legalised online gambling as of 2026.

Online Casinos in the USA

Licensed online casinos are available in seven US states. Each state licences its own operators and sets its own rules. The biggest and most competitive market is New Jersey, followed closely by Pennsylvania and Michigan.

All licensed US online casinos must use certified random-number-generation software, publish payout rates and connect to the state's self-exclusion register. You must be physically located within the state to play — operators use geolocation technology to verify this in real time.

The top operators nationwide

DraftKings, FanDuel and BetMGM are the three largest online casino operators in the US, present in virtually every legal state. Caesars, Borgata (MGM Resorts), BetRivers and Golden Nugget round out the major brands. 888 Casino has a long-standing presence in New Jersey and Delaware.

Geolocation — why you must be in the state

Licensed US online casinos use your device's GPS and IP address to confirm you are physically inside a legal state. VPNs are detected and will get your account flagged, your access blocked and any winnings withheld. You must sign up with an operator licensed in your home state, but once registered, you can also play at that same operator in any other state where they hold a licence.

Bonuses and promotions

US online casino bonuses are generous by global standards, particularly in competitive markets like New Jersey. Deposit match bonuses of 100% up to $1,000 are common. Pennsylvania operators tend to offer less generous terms due to high state tax rates (54% on online slots), but the operator selection is large. Always check wagering requirements before claiming any bonus.

Online Poker in the USA

Online poker is legal in seven states: New Jersey, Pennsylvania, Michigan, Nevada, Delaware, West Virginia and Connecticut. New Jersey and Pennsylvania have the most player traffic. Multi-state liquidity sharing is making games bigger than ever.

The Multi-State Internet Gaming Agreement (MSIGA) lets players in participating states compete at the same tables. New Jersey, Nevada, Delaware, Pennsylvania, Michigan and West Virginia all share player pools — meaning more players, bigger tournaments and healthier cash games at all hours.

Taxes on poker winnings

Unlike Canada and the UK, the US taxes gambling winnings. Poker winnings are taxable income. Operators must report wins of $5,000 or more to the IRS. If you play regularly, keep detailed records of every session — you can offset documented losses against your winnings when you file your annual return.

Live poker in the USA

The World Series of Poker (WSOP) in Las Vegas is the biggest poker festival in the world. The Main Event draws thousands of players every summer and is broadcast globally. Las Vegas poker rooms run 24/7, with stakes from $1/$2 up to high-roller tables. The Borgata in Atlantic City and the Bellagio in Las Vegas have the largest live poker programmes on the East and West Coasts respectively.

Playing on mobile

PokerStars, WSOP.com and BetMGM Poker all have apps for iOS and Android. PokerStars allows up to 4 tables simultaneously on mobile. WSOP.com is the best option if you want to share liquidity across the most states — it connects NJ, PA, NV, WV and DE in one player pool.

Sports Betting in the USA

Sports betting is legal in 38+ states and Washington DC, with more legalising every year. The market has exploded since the 2018 Supreme Court ruling. DraftKings, FanDuel and BetMGM dominate, but regional sportsbooks compete fiercely on odds and promotions.

Online sports betting apps are available in most legal states and have driven rapid market growth. Some states initially required in-person registration at a licensed casino, but most have moved to fully online sign-up. Geolocation technology verifies you are physically inside the state each time you place a bet.

Same-game parlays

Same-game parlays (SGPs) are one of the most popular bet types in the US. You combine multiple selections from a single game — team to win, a player to score, total points over a number — into one bet. The potential payout multiplies, but all legs must hit. All major US sportsbooks now offer SGPs for NFL, NBA, MLB and NHL games.

Taxes on sports betting winnings

Sports betting winnings are taxable income. Sportsbooks report winnings of $600 or more to the IRS if the payout is at least 300× the wager. You should report all gambling winnings regardless of size, and you can deduct documented gambling losses up to the total of your winnings. Keep records — even a simple spreadsheet of sessions counts.

Staying in control

All licensed US sportsbooks must offer tools to help you manage your betting: deposit limits, loss limits, session time limits and cooling-off periods. Every legal state runs a self-exclusion programme that bars you from all licensed operators in that state. The National Council on Problem Gambling helpline is 1-800-522-4700, free and available 24/7.

Lottery in the USA

Lotteries are available in 45 US states. Powerball and Mega Millions are the two national multi-state games, with jackpots that can run into the billions. Unlike in the UK, lottery prizes are taxed — and the tax can be substantial.

Powerball

Powerball draws every Monday, Wednesday and Saturday. Pick 5 numbers from 1–69 and 1 Powerball number from 1–26. Tickets cost $2 each. The jackpot starts at $20 million and rolls over until someone wins. The record Powerball jackpot was $2.04 billion in November 2022.

Mega Millions

Mega Millions draws every Tuesday and Friday. Pick 5 numbers from 1–70 and 1 Mega Ball from 1–25. Tickets cost $2 each. The jackpot starts at $20 million. The record Mega Millions jackpot was $1.602 billion in August 2023.

Taxes on lottery winnings

Federal tax is 37% on large lottery prizes. State taxes range from 0% (in states with no income tax) to over 10%. Jackpot winners can choose a lump sum (roughly 60% of the advertised amount before taxes) or an annuity paid out over 29 years. Most financial advisers note that the after-tax difference between lump sum and annuity depends heavily on your state, investment horizon and personal tax situation.
