Michigan has one of the most comprehensive regulated online casino markets in the United States. This guide breaks down every law, tax rate, licensing requirement, and regulatory body that governs online gambling in the Great Lakes State. The Lawful Internet Gaming Act (HB 4311, signed December 2019) established the framework. The MGCB oversees all 15 licensed operators (the maximum allowed). Michigan’s iGaming market generated $2.2 billion in adjusted gross receipts in 2024, with a graduated tax structure of 20-28% on operator revenue.
The tethering system requires every online casino to partner with one of Michigan’s 3 Detroit commercial casinos or 12 federally recognized tribes. In 2026, the regulatory picture continues to tighten: the FY2026 budget increased MGCB funding, the board maintains zero-tolerance enforcement against offshore operators (155+ cease-and-desist letters in 2025), and FanDuel received approval for multi-state poker between Michigan and Pennsylvania in April 2026. This is a purely informational regulatory guide. For casino recommendations, visit our Michigan Online Casinos companion guide.
Michigan’s Three Key Online Gambling Laws
| Law | Bill Number | What It Covers | Signed | Launched |
|---|---|---|---|---|
| Lawful Internet Gaming Act | HB 4311 (Act 152) | Online casinos + online poker | Dec 20, 2019 | Jan 22, 2021 |
| Lawful Sports Betting Act | HB 4916 | Retail + mobile sports betting | Dec 20, 2019 | Jan 22, 2021 |
| Fantasy Contests Consumer Protection Act | HB 4308 | Daily fantasy sports regulation | Dec 20, 2019 | Dec 2019 |
The Lawful Internet Gaming Act (HB 4311): Deep Dive
Representative Brandt Iden introduced HB 4311 in March 2019. The 13-page document declares “it is in the best interest of this state and its citizens to regulate this activity.” This wasn’t Michigan’s first attempt. Governor Rick Snyder vetoed a previous version in 2018, citing concerns about problem gambling and potential impact on the Michigan Lottery. The 2019 version represented a compromise between Governor Whitmer’s administration, tribal interests, and the Detroit commercial casinos.
Key provisions of the compromise included guaranteed funding for the School Aid Fund and the First Responder Presumed Coverage Fund from gambling revenue. Under HB 4311, each casino operator can offer internet gaming under 2 separate brands: one for poker and one for casino games, or one combined platform. This means the theoretical market maximum is 30 total online casino and poker sites across the 15 licence holders.
The MGCB oversees all operations including tribal operators. The Act establishes baseline permitted games: poker, blackjack, card games, and slots. Lottery-style pick-numbers games are excluded, preserving the Bureau of Lottery’s exclusive domain. Licences last 5 years and are renewable. The free play deduction schedule incentivised early market growth: years 1-3 allowed a 10% deduction of gross receipts, year 4 dropped to 6%, year 5 to 4%, and year 6 onward eliminated the deduction entirely. Operators must submit monthly reports covering wagers, payouts, bonus play, deductions, and adjusted gross receipts.
The Lawful Sports Betting Act (HB 4916)
Introduced in September 2019 by Representative Iden, this 14-page document authorized both retail and mobile sports betting. The 3 Detroit commercial casinos opened retail sportsbooks in March 2020. Tribal casinos began offering retail sports betting in summer 2020. Online sports betting launched statewide on January 22, 2021, simultaneously with online casinos and poker, making Michigan the first state to launch all three verticals at once.
Each casino operator is limited to 1 internet sports betting brand (compared to 2 casino brands). Tribal casinos receive 1 sportsbook licence per tribe, not per casino location. The Act defines “athletic event” broadly but specifically excludes pari-mutuel horse racing, high school events (unless the majority of participants are 18+), casino games, and fantasy contests. Retail sportsbooks operate at Detroit commercial casinos only; online operates statewide under MGCB oversight.
Technical requirements include GLI-33 standards and ISO 27001 annual security assessments. All servers must be physically located in Michigan. The tax rate is 8.4% on adjusted gross sports betting receipts. Detroit casinos pay an additional 1.25% city services fee. The federal excise tax of 0.25% on handle applies nationally.
Michigan’s Casino Tethering System Explained
Every online casino and sportsbook licence in Michigan must be tethered to an in-state land-based casino. This tethering system is the structural backbone of Michigan’s iGaming market. The 3 Detroit commercial casinos (MGM Grand Detroit, MotorCity Casino Hotel, Hollywood Casino at Greektown) plus 12 federally recognized tribes create the maximum of 15 potential licence holders.
Each licence supports up to 2 online casino brands (1 poker platform plus 1 casino platform, or 1 combined) and 1 sportsbook brand. The land-based casino licence holder is legally responsible to the MGCB for all compliance. The partnered operator (FanDuel, DraftKings, BetMGM, etc.) manages the platform, technology, and marketing. Partnership agreements involve revenue-sharing, brand usage rights, and operational integration.
All 15 licences are currently spoken for. No new standalone applications are possible. Entry into the Michigan market is only available through acquiring an existing partnership, positioning as a licensed supplier, or waiting for an incumbent to exit. Most partnerships are structured as 5-10 year multi-year agreements. The scarcity of licences means patience and positioning matter as much as product innovation for potential market entrants. For the full list of platforms, see Michigan Online Casinos.

Who Regulates Online Gambling in Michigan?
Michigan Gaming Control Board (MGCB)
The MGCB is Michigan’s lead gambling regulator. It oversees commercial casinos, tribal compliance, sports betting, internet casino gaming, daily fantasy sports, and horse racing. The board issues all licences, enforces the Lawful Internet Gaming Act and Lawful Sports Betting Act, supervises technical testing, mandates player verification, and approves gaming systems. In 2025-2026, the MGCB issued a wave of cease-and-desist orders against offshore operators, with Bovada being the highest-profile brand to exit the Michigan market. The “Don’t Regret the Bet” responsible gambling campaign runs statewide. The FY2026 budget increased MGCB funding for enforcement and oversight. Executive Director Henry Williams stated: “Illegal gambling operators threaten the safety of our citizens and the integrity of our gaming industry.”
Michigan Lottery / Bureau of State Lottery
The Michigan Lottery holds a constitutionally protected state monopoly on draw games, instant tickets, keno, and iLottery products. It cannot expand into casino-style games, which remain the exclusive domain of MGCB-licensed operators. IGT is contracted as the technology partner through 2031. The Bureau of State Lottery also regulates charitable gaming under the Bingo Act.
Tribal Gaming Commissions
Michigan’s 12 federally recognized tribes operate Class III casinos under tribal-state compacts negotiated pursuant to the Indian Gaming Regulatory Act (IGRA). Each tribal gaming commission licenses and oversees facilities on their respective lands. Tribal sovereignty grants broad autonomy, though the National Indian Gaming Commission (NIGC) provides federal oversight. The MGCB retains inspection rights under the governor’s authority. Compacts outline permitted games, revenue-sharing formulas, and exclusivity provisions. Tribes pay 2% of net winnings to the state plus 1-12% to the Michigan Strategic Fund and Michigan Economic Development Corporation.
Department of Insurance and Financial Services (DIFS)
DIFS regulates the financial and payment systems used in Michigan’s gambling market. It oversees anti-money laundering (AML) compliance for operators and works within the Bank Secrecy Act federal framework. DIFS ensures the integrity of payment channels used in gaming transactions, including deposit processing, withdrawal systems, and fund segregation.

Detroit receives separate city taxes distributed as 30% city services, 65% Internet Gaming Fund, and 5% Michigan agriculture equine fund (capped at $3 million). Detroit is guaranteed $183 million annually from online gaming revenue. As of 2025, Michigan operators have contributed over $1 billion in lifetime tax revenue, with monthly contributions averaging $28.6 million in state taxes plus $10.5 million to local jurisdictions.

Offshore Casino Enforcement in Michigan
Offshore and unlicensed casinos are not authorised by the MGCB. In 2025, the board issued a wave of cease-and-desist orders against unlicensed operators. Bovada, the highest-profile unlicensed brand serving US players, exited the Michigan market following MGCB enforcement action. Executive Director Henry Williams stated: “Illegal gambling operators threaten the safety of our citizens and the integrity of our gaming industry. We take this seriously.”
The 2026 enforcement posture continues with zero-tolerance for unlicensed operators. The American Gaming Association estimates $13.3 billion in lost tax revenue annually from unregulated US gambling nationwide. MGCB-licensed sites provide independent game testing, dispute resolution, and full consumer protection. Offshore sites operate without Michigan regulatory recourse if issues arise. Enforcement consistently targets operators, not individual players.
Responsible Gambling Laws and Resources
All MGCB-licensed operators are required by law to implement deposit limits, wagering limits, time limits, permanent and temporary self-exclusion, reality checks every 30 minutes, auto-play prohibition, and display of the 1-800-GAMBLER helpline. The “Play It Smart, Michigan” and “Don’t Regret the Bet” campaigns run statewide. The FY2025 budget allocated $3 million additional to the Compulsive Gaming Prevention Fund. The FY2026 budget includes further funding increases. Advertising cannot target minors or self-excluded persons. March is officially Responsible Gambling Month in Michigan under a Governor Whitmer proclamation.
