Illinois lawmakers are pushing a new bill that would prevent cities like Chicago from adding their own taxes or regulations to sports betting. The measure, filed this week as House Bill 4171, comes in response to Mayor Brandon Johnson’s proposal to levy a city tax on online wagering revenue.
State lawmakers, led by Dan Didech, chair of the Illinois House Gaming Committee, argue that allowing cities to create their own taxes or rules on sports betting could cause several problems:
Allowing individual cities and counties to set their own sports betting taxes or rules could lead to a confusing patchwork of regulations across Illinois. Operators might have to comply with different reporting standards, licensing fees, or tax rates in each jurisdiction, increasing administrative costs and legal risks.
This inconsistency could discourage smaller or newer sportsbooks from entering the market and complicate operations for those already licensed statewide. Lawmakers argue that maintaining a uniform regulatory framework helps ensure fairness, transparency, and efficiency. This makes it easier for both the state to oversee the industry and for operators to comply with the law.
Local sports betting taxes that raise costs for operators could ultimately push more bettors toward offshore or illegal gambling sites, where there are no consumer protections or regulatory safeguards. These unlicensed platforms often lack measures to ensure fair play, secure personal data, or prevent problem gambling.
Unlike state-regulated sportsbooks, they don’t contribute tax revenue, verify user age, or provide recourse for disputes. If more players join these platforms, the state loses not only direct tax revenue but also the broader economic benefits tied to legal betting, such as job creation, licensing fees, and tourism dollars.
If legal betting becomes too expensive or complicated due to added local taxes, more players may turn to these risky alternatives. This would undermine both public safety and the integrity of Illinois’s regulated market.
House Bill 4171 was officially filed with the Illinois House Clerk on October 20, 2025, and is expected to be taken up when lawmakers return for the 2026 legislative session in January. The bill will likely be referred to the House Gaming Committee, where hearings and amendments could shape its final language before it moves to a full House vote.
If the measure advances through both chambers, it would take effect immediately upon the governor’s signature, effectively blocking Chicago’s proposed 10.25% online betting tax before it can be implemented.
Illinois already has one of the highest tax rates on sports betting operators in the country. This has created an unfavorable environment for regulated sports betting, so banning this new Chicago tax is important for this market.
