How the law works for online casinos in Michigan

Michigan regulates internet gaming under the Lawful Internet Gaming Act, signed by Governor Gretchen Whitmer on 20 December 2019. Regulators spent the following year writing the rules, and eight online casinos went live on the same day in January 2021.

One regulator, not two

Unlike New Jersey, where licensing and enforcement sit with separate bodies, Michigan runs both through the Michigan Gaming Control Board. The MGCB licenses operators, platform providers and suppliers, audits games and finances, sets cybersecurity standards, and enforces responsible gambling rules.

The partnership requirement

No brand operates on its own licence. Each online casino must partner with either one of Detroit’s three commercial casinos or one of Michigan’s 12 federally recognised tribes. That is why the market is capped at fifteen brands, and why several nationally known names run under a tribal partner in the Upper Peninsula.

What a licence costs

• Application fee: $50,000
• Initial licence fee: $100,000
• Annual fee thereafter: $50,000
• Licence term: five years, renewable

Age and location rules

Players must be 21 or over. Operators run identity checks at sign-up and geolocation during play, so accounts only work inside state lines. Residency is not the test: a visitor physically in Michigan can play, a resident travelling elsewhere cannot.

The Michigan online casino market in numbers

The Michigan Gaming Control Board publishes monthly figures for every licensed operator, which makes the market unusually transparent. The numbers below come from those reports.

Online dwarfs the casino floor

In March 2026 Detroit’s three commercial casinos took $112.3 million between them, while online gaming produced $322.1 million. Online accounted for roughly two thirds of all reported gambling revenue in the state that month.

How the tax works

Michigan taxes online casino revenue on a sliding scale based on each operator’s adjusted gross receipts, starting at 20% for the smallest tier and rising to 28% for operators above $12 million. The money funds the Internet Gaming Fund, a compulsive gambling prevention fund, the First Responder Presumed Coverage Fund and the State School Aid Fund.

Player protection and responsible gambling

The protections attached to an MGCB licence are enforceable, and there is a regulator with the power to act when an operator falls short. That is the practical difference between the licensed market and anything outside it.

What licensed operators must provide

• Identity and age verification at sign-up, with a hard 21+ minimum.
• Geolocation checks that block play from outside state lines.
• Games and random number generators audited by the MGCB.
• Deposit, wager, loss and time limits that players set themselves.
• Cooling-off periods and account self-exclusion.
• Cybersecurity standards set and reviewed by the regulator.

Two separate exclusion programmes

Michigan runs more than one route out. The Disassociated Persons List covers the Detroit commercial casinos, while the Internet Gaming and Sports Betting Responsible Gaming Database covers online play across licensed operators. Both are administered through the MGCB.

Enforcement against unlicensed sites

The MGCB has been unusually active here. Between December 2025 and April 2026 it issued cease-and-desist orders to 45 offshore operators taking Michigan wagers without a licence, part of a broader run of enforcement actions.

Where to get help

• Michigan Problem Gambling Helpline: 1-800-270-7117, staffed around the clock.
• 1-800-GAMBLER: national helpline, also available at 800gambler.org.
• Michigan Association on Problem Gambling: state-level support and treatment information.
• BeGambleAware: guidance and self-assessment tools at begambleaware.org.

Signs worth taking seriously

Chasing losses, gambling with money meant for something else, hiding how much you play, or finding it crowds out work and relationships are all reasons to pause and use the limit tools. The state also runs DontRegretTheBet.org with further resources.

How to choose between online casinos in Michigan

With fifteen licensed MI online casinos to pick from, the licence itself stops being a differentiator. Everything on the MGCB list has cleared the same bar, so the choice comes down to fit.

What actually varies

• Library size: the range is wide, from around 400 titles to over 3,600. If you play one category, check that category rather than the headline number.
• Commercial or tribal partner: sites tied to Detroit casinos tend to offer cash at the cage in the city, while tribal partners put that option in the Upper Peninsula or northern Michigan.
• Loyalty schemes: the national groups let you spend points offline as well, which matters if you visit their properties elsewhere.
• Bonus terms: wagering requirements matter more than headline amounts. A smaller offer at 1x beats a larger one at 30x.
• App quality: ratings vary sharply between operators, from near-perfect to under 3 out of 5.
• Withdrawal speed: a real difference between brands and a common source of complaints.

Checks worth doing first

• Confirm the site appears on the MGCB list of authorised operators.
• Read the wagering requirement and game weighting before depositing.
• Set deposit and loss limits at sign-up rather than later.
• Check which methods are supported for withdrawals, not just deposits.
