Gambling Laws in Connecticut: Rules, Taxes, and Penalties

Gambling laws in Connecticut permit casino play at two tribal casinos, online casino gaming, retail and online sports betting, the state lottery, keno, fantasy contests, and municipally licensed charitable games like bingo and raffles. The Department of Consumer Protection (DCP) regulates the industry through its Gaming Division, age limits run 18 or 21 depending on the activity, winnings are taxed, and unauthorized gambling can carry penalties up to a class D felony.

What You Can Legally Play

Two federally recognized tribes anchor Connecticut’s casino industry. The Mashantucket Pequot Tribal Nation runs Foxwoods Resort Casino, and the Mohegan Tribe of Indians of Connecticut runs Mohegan Sun. Both operate under compacts signed with the state in the early-to-mid 1990s pursuant to the federal Indian Gaming Regulatory Act.¹

Public Act 21-23, passed in 2021, opened up the online market. The tribes hold master wagering licenses covering online casino gaming and sports betting, while the Connecticut Lottery Corporation (CLC) offers retail and online sports wagering, fantasy contests, keno, and lottery draw games.²³ Fantasy contests must base results predominantly on the accumulated statistics of real athletes across multiple events, not on the outcome of a single game or point spread.⁴

Social gambling between friends, where no one profits from organizing the game, sits outside the criminal statute.⁵ Everything else needs to run through a licensed operator or an approved charitable permit.

Age Limits and Where You Can Play

Connecticut uses two age floors. You must be 21 or older to gamble at a casino, place a sports bet in person or online, or play online casino games. The minimum drops to 18 for lottery tickets, keno, and fantasy contests.⁶

Operators verify age at the door and at online registration using government-issued identification. A minor who places a wager in any authorized gambling activity can be charged with a class A misdemeanor, which carries up to 364 days in jail and a fine of up to $2,000. Anyone who knowingly lets a minor gamble faces the same charge.⁷

Online play requires you to be physically inside Connecticut. Licensed platforms use geolocation technology to block wagers from outside the state and run identity checks before allowing play, along with encryption, fraud detection, and know-your-customer procedures.⁸

Taxes on Gambling Winnings

Money you win gambling in Connecticut is taxable, at both the federal and state level. That applies whether you hit a casino jackpot, cash a lottery ticket, or collect a sports betting payout online.

Federal Withholding

The federal government treats gambling winnings as ordinary income. When your winnings minus your wager exceed $5,000, the payer withholds 24% for federal income tax and issues IRS Form W-2G.⁹ Smaller wins still have to be reported on your federal return even if nothing was withheld when you were paid.

Connecticut State Withholding

Connecticut withholds state income tax at a flat 6.99% on gambling winnings that are either subject to federal withholding (proceeds minus wager over $5,000) or federally reportable ($600 or more and at least 300 times the wager amount).¹⁰ That 6.99% figure matches the state’s top marginal income tax bracket; your actual liability depends on your total income for the year.¹¹ Both residents and nonresidents who win in Connecticut are subject to the withholding.

Deducting Losses

You can deduct gambling losses on your federal return, but only if you itemize on Schedule A, and only up to the amount of gambling income you report. Losses can never take you below zero.¹²

The IRS also expects you to keep a running diary of wins and losses, backed up by receipts, tickets, or statements showing amounts.¹² Recreational players often skip this step. Without contemporaneous records, the IRS can deny loss deductions outright, and you end up paying tax on the full reported winnings with no offset.

If Gambling Is Your Job

Professional gamblers report their activity on Schedule C rather than deducting losses on Schedule A, which changes the arithmetic but also subjects net earnings to self-employment tax. The Supreme Court’s 1987 decision in Groetzinger v. Commissioner sets the standard: full time, in good faith, with regularity, and pursued for income rather than recreation. The taxpayer carries the burden of proving that status.

Penalties for Illegal Gambling

Connecticut’s criminal gambling statutes escalate quickly once you step outside the licensed and social-game exceptions.⁵

Simple gambling, soliciting someone to gamble, or being present during illegal gambling is a class B misdemeanor, up to six months in jail and a fine of up to $1,000.
Running an illegal gambling operation as a business (professional gambling) is a class A misdemeanor, up to 364 days in jail and a fine of up to $2,000.
Knowingly owning, selling, repairing, or transporting gambling equipment outside a lawful permit is also a class A misdemeanor.
Certain aggravating facts push the offense to a class D felony, up to five years in prison and a fine of up to $5,000. Those include subscribing to a phone line under a fake name for gambling purposes, and maintaining a gambling location with barricades, lookouts, or alarm systems.

The misdemeanor sentencing figures above reflect Connecticut’s general sentencing framework.¹³ A dedicated State Police legalized gambling investigative unit handles detection alongside the DCP and federal agencies.¹⁴

For licensed operators, the DCP handles compliance through audits, investigations, and administrative actions. Fines, suspensions, and revocations are all on the table, and a licensee facing discipline can request an administrative hearing.¹⁵

Bingo, Raffles, and Bazaars

Charitable games run on a separate track. Bingo, raffles, and bazaars are legal in Connecticut but regulated at the municipal level, not by the DCP. Each town decides whether to allow the activity, and the local chief of police (or the chief executive officer if the town has no police chief) issues permits.¹⁶

Only qualifying nonprofits that have existed for at least two years can apply, including charitable, civic, educational, fraternal, veterans’, and religious organizations, plus volunteer fire departments and granges. Bingo permits come in three classes:

Class A: one day each week, renewed annually, permit fee up to $75.
Class B: up to ten successive days, limited to two permits per organization per year, permit fee up to $10 per day.
Class C: one day each month, renewed annually, permit fee up to $50.

Organizations file a financial return with the municipality within 10 days of each event and pay 5% of gross receipts minus prizes to the town.¹⁶

Self-Exclusion and Problem Gambling Help

Connecticut runs a voluntary self-exclusion program that blocks you from all forms of online gaming and retail sports wagering. You sign up online through a licensed operator’s platform or at a DCP-approved location, using government-issued photo identification, and you acknowledge that any winnings earned while on the list are forfeit.¹⁷

You pick the length: one year, five years, or lifetime. You cannot come off the list before your chosen period ends.¹⁷

If gambling is causing harm, help is available. The Connecticut Council on Problem Gambling runs a helpline at 888-789-7777. The Department of Mental Health and Addiction Services offers problem gambling services at 860-344-2244. The national helpline, 1-800-GAMBLER, is staffed around the clock.¹⁸
