Starting January 1, 2026, Chicago will implement a new local tax on sports betting revenue after Mayor Brandon Johnson chose not to sign or veto the city’s recently approved budget. This 10.25% levy on sportsbook operator revenue adds to an already intricate tax structure faced by operators in Illinois.
The new tax measure is part of a $16.6 billion budget passed by the Chicago City Council. City officials assert that the additional tax will provide a new stream of revenue for municipal services. However, industry groups caution that the policy could disrupt legal operations, drive players to illegal betting avenues, and create compliance issues due to unresolved licensing provisions.
Chicago’s municipal rules allow the budget ordinance to become law without the mayor’s signature. Mayor Johnson proposed the sports betting tax in October as a strategy to close a budget gap. However, the final version came from a City Council-led budget alternative after aldermen rejected the mayor’s corporate head tax proposal. This places a new city-level tax on sportsbook revenue from wagers within Chicago, with no transition period, making it effective from January 1.
Operators are concerned about the cumulative tax burden this new levy imposes. With Illinois’s progressive sports betting tax rates already ranging from 20% to 40% and Cook County adding another 2%, the addition of Chicago’s tax pushes the minimum combined tax burden to over 32%. For prominent national brands reaching the state’s top tax tier, rates on Chicago-generated revenue could surpass 50% at times during the fiscal year. Market analysts suggest these stacked taxes alter the economics of regulated sports betting, especially in urban markets where margins are tight due to promotional costs and compliance expenses.
A major point of contention is the requirement for sportsbooks to obtain a Chicago license without a clear process for doing so. The Sports Betting Alliance, representing major U.S. sportsbook operators, highlighted this issue in a letter to city officials, stating that the lack of a licensing framework could put companies in a legal gray area. The group stated, “This lack of clarity introduces regulatory uncertainty that could force operators to suspend activity in Chicago while compliance pathways are resolved.” The timing of these changes, dictated by the budget process, leaves little room for necessary rulemaking or consultations before the tax’s implementation.
Industry stakeholders express worries that higher taxes will change player behavior rather than merely increase public revenues. They argue that the new tax could drive players toward illegal sportsbooks that avoid taxes and lack consumer protections. When legal operators face repeated penalties, the regulated market becomes less competitive, which defeats the original purpose of legalizing sports betting. Research from other states indicates that significant tax hikes can lead to reduced promotions, less favorable odds for bettors, and slower innovation, all of which can diminish the appeal of licensed platforms.
At the state level, Chicago’s new tax has drawn attention from lawmakers in Springfield. Some argue that gambling policy should remain consistent statewide. Illinois state Representative Daniel Didech, chair of the House Gaming Committee, introduced a bill to prevent local governments from imposing their own taxes on gambling activities, citing concerns about fragmentation and regulatory overlap. Conversely, state Senator Patrick Joyce proposed reducing Chicago’s share of state-distributed funds by the amount equivalent to the revenue generated from the city’s sports betting tax. This measure is described as a safeguard against double taxation. Although neither proposal has progressed to a vote, their introduction reflects growing tension between city and state policymakers over gambling revenue control.
City officials project that the new Chicago sports betting tax will generate roughly $26 million annually, assuming Chicago accounts for about 40% of sportsbook revenue in Cook County. Yet, industry observers warn these estimates assume stable betting behavior and do not consider potential market reactions, such as a decrease in betting volume, operator pullback, or a shift to offshore platforms. Illinois sportsbooks have reported strong performance in 2025, with adjusted gross revenue exceeding the previous year’s figures. However, operators note that recent state-level tax changes, like the mid-2025 per-wager surcharge, have started affecting betting patterns, with a decline in wager volume despite overall revenue growth.
