The market

Illinois moved to a graduated tax that climbs as high as 40% on the largest operators, one of the most aggressive structures in the country. The market is large and active, but the rising tax has pushed some books to trim bonuses. Worth watching as operators adjust.

What this means for matched betting

Illinois has online sportsbooks, so the sign-up and reload offers our tools track are usable here. The wider the operator field, the more promotions there are to turn into locked-in profit. Start with the free calculators, then work the live offers.

Figures are indicative and can change as markets evolve. Always confirm current rules, tax and the legal age with the IGB before you bet.
