Illinois House Committee Advances Bill to Block Local Regulation of Sports Betting (Chicago, IL) – The Illinois House Gaming Committee on Wednesday advanced legislation that would prevent home rule municipalities from imposing their own regulations or licensing requirements on sports betting companies, setting up a broader debate over local control and the state’s growing gaming industry.
House Bill 4171, sponsored by Rep. Daniel Didech, D-Buffalo Grove, cleared committee with bipartisan support. The measure aims to ensure sports wagering is regulated exclusively at the state level, a move supporters say would create consistency for operators and consumers.
The bill comes in response to Chicago’s decision to enact a municipal licensing requirement and a 10.25% tax on sports betting operators beginning Jan. 1. Industry groups and some lawmakers have warned that local taxes layered on top of state levies could drive bettors to illegal markets.
Didech and Rep. Curtis Tarver, D-Chicago, raised those concerns in a November letter to Chicago aldermen, noting that the General Assembly has already increased the state’s sports betting tax burden twice in recent years. Illinois now uses a graduated tax rate that can reach as high as 40%, along with a per-wager assessment enacted in 2025.
In their letter, the lawmakers cautioned that allowing municipalities to add their own taxes could create a “fragmented and unstable framework” for a state-regulated industry and potentially lead to a patchwork of local taxes in other policy areas.
The Sports Betting Alliance, an industry group representing major online operators, praised the committee’s action. In a statement, the organization argued that uniform statewide regulation would help keep bettors within the legal market and preserve consumer protections.
Since legalization, sports betting has become a significant revenue source for Illinois, but recent data from the Illinois Gaming Board shows a decline in legal wagering activity. The alliance cited figures indicating three consecutive monthly drops in bets placed between September and November 2025, attributing the trend in part to rising taxes and regulatory complexity.
“The data is a warning sign that Illinois’ patchwork of regulations has direct consequences to the state’s revenues as well as public policy goals of responsible gaming,” the group said, arguing that higher costs can push bettors toward unregulated offshore sites or illegal bookmaking operations.
Chicago’s sports betting tax is currently being challenged in court by the alliance, adding another layer of uncertainty as lawmakers consider the proposed statewide preemption.
HB 4171 now heads to the full House for consideration, where it is expected to spark debate between advocates of uniform state oversight and local leaders seeking additional revenue streams from the rapidly expanding sports betting industry.
