Illinois yesterday became the latest US state to impose a direct tax on targeted digital advertising, passing SB 3019 - a sweeping revenue bill projected to raise more than $800 million - as part of a $55.9 billion fiscal 2027 state budget. The measure cleared both chambers of the General Assembly on June 1, 2026, and now awaits the signature of Governor J.B. Pritzker.

The passage marks a significant moment for the advertising industry. For years, efforts to tax digital advertising at the state level have faced legal and political obstacles. Maryland enacted the first such law in the US in 2021, but a state court later struck it down on constitutional grounds, a development covered by PPC Land. Washington State took a different approach in 2025, extending its standard retail sales tax to advertising services from October 1 of that year, implementing a 6.5 percent state rate plus applicable local charges. Illinois now adds a third model - a standalone excise on targeted advertising services specifically - at a rate of 10 percent.

What the bill does

The Targeted Advertising Services Tax Act, created by SB 3019, imposes a 10% levy on the gross receipts derived from targeted advertising services provided within Illinois. According to the bill text, the tax applies to any business whose annual cumulative gross receipts from such services exceed $1 million during the previous 12 months. The threshold means smaller operators are excluded, but the language encompasses companies earning revenue from digital, social media, and display advertising once that threshold is crossed.

Three new levies take effect on January 1, 2027. Beyond the targeted advertising tax, the bill imposes a tax on digital asset transactions and creates a graduated social media platform fee structure.

The digital asset tax is set at 0.2% of the value of a digital asset at the point a customer in Illinois receives any digital asset business activity. Digital asset brokers - including exchanges, brokerages, and transmission facilities - are required to collect the tax and remit collections to the state. According to the Illinois Policy Institute, this provision is projected to raise approximately $60 million annually.

Social media fee tiers

The social media fee structure operates on a tiered basis linked to the number of in-state users a platform carries. Platforms with more than 100,000 Illinois users, but not more than 500,000, pay 10 cents per month per user. Those with more than 500,000 but not more than 1 million Illinois users pay a flat $40,000, plus 25 cents per month multiplied by the number of users above 500,000. Platforms exceeding 1 million Illinois users pay $165,000, plus 50 cents per month multiplied by the number of users above 1 million.

According to Bloomberg Tax, the Illinois Policy Institute estimated the graduated fee structure would raise more than $200 million. The targeted advertising levy's total revenue remains less certain, but the institute also projected it would bring in $200 million for the state.

The broader revenue package

The advertising and digital levies sit within a much larger revenue bill. According to Bloomberg Tax, more than $800 million in new tax revenue is expected to flow into Illinois's coffers under several levies within SB 3019, which was designed to support the broader $55.9 billion fiscal 2027 budget.

Large corporations will face higher effective tax rates through a change in how net operating losses (NOLs) are treated. The bill restricts NOL deductions to $500,000 or 15% of net income, whichever is greater, during fiscal year 2027. The allowed percentage is scheduled to rise annually until it reaches 80% in 2031. According to Bryce Hill, director of fiscal analysis at the Illinois Policy Institute, the NOL change amounts to a corporate income tax increase of $300 million. Hill argued the cap "can lead to companies paying far higher effective tax rates than the state's statutory corporate income tax rate."

One element that did not survive into the final bill is worth noting. Governor Pritzker had sought to eliminate the independent Illinois Tax Tribunal and pull adjudication of tax disputes into the Illinois Department of Revenue. According to Keith Staats, president of the Taxpayers' Federation of Illinois, business interests successfully defeated that plan. The budget fully funds the tribunal, and a separate bill - HB 862 - makes only minor amendments to tribunal functions, including modifications to ethical standards specifying that judges cannot continue to serve more than 60 days after their term expires.

Consumers receive a small relief measure: a back-to-school sales tax holiday scheduled for August 7-16. The bill also pauses a 1.3-cent per gallon gas tax increase for six months - the increase had been scheduled to launch July 1 - with the pause extended until January 1, 2027.

Prediction markets enter the tax base

A fourth component of the bill brings prediction markets into Illinois's Sports Wagering Act tax structure. Prediction markets are platforms where participants trade contracts based on the outcome of real-world events including elections, economic data releases, and sports results. Prices on such contracts reflect the aggregate market view of probabilities, with participants buying or selling "yes" or "no" positions at prices corresponding to perceived likelihood.

The sector has grown rapidly. According to a report by the analytics firm TRM Labs cited in Bloomberg Tax's coverage, trading volume on prediction markets hovered around $1.2 billion per month in 2025. By 2026, that figure had surged to $20 billion per month. Earlier this year, Kentucky became the first US state to impose a tax on such markets. Illinois now follows.

The scale of that growth matters for advertisers and ad platforms alike. PPC Land reported in January 2026 that Google Ads opened advertising to prediction markets starting January 21, 2026, with access limited exclusively to platforms authorized by the Commodity Futures Trading Commission as Designated Contract Markets or NFA-registered brokerages. The Illinois tax regime now adds a compliance layer for platforms operating in the state.

Vote tallies and legislative path

The bill's passage came after an intensive final stretch of the legislative session. SB 3019 was originally filed on January 29, 2026, by Sen. Patrick J. Joyce - at that point focused on agricultural borrowing rules. The bill was substantially transformed through the amendment process.

The Senate passed the original measure on April 14, 2026, by a vote of 55-0-4. The House amended the bill and passed it on May 31, 2026, by a vote of 73-41-4 - a considerably narrower margin reflecting partisan friction over the tax increases. The Senate concurred with both House Floor Amendments 1 and 2 on June 1, 2026, each by a vote of 36-19-4. Both chambers required a 3/5 supermajority vote, underscoring the procedural hurdles involved.

The final bill lists Sen. Celina Villanueva as chief Senate sponsor, alongside co-sponsors Sen. Elgie R. Sims Jr., Sen. Mark L. Walker, Sen. Mike Porfirio, Sen. Mattie Hunter, and Sen. Rachel Ventura. In the House, Rep. Curtis J. Tarver II served as alternate chief sponsor.

A motion to reconsider the House vote was filed by Rep. Will Guzzardi on May 31, 2026, but was withdrawn the same day, clearing the path for Senate concurrence.

According to the Illinois Senate Democrats, Sen. Villanueva called the package a "responsible revenue" measure "prioritizing working families." Gov. Pritzker issued a statement saying he looked forward to signing the budget, hours after the spring legislative session adjourned.

Opposition and structural critique

Not everyone accepted that framing. The Illinois Policy Institute, a fiscal policy think tank that favors conservative tax policy, issued pointed criticism. According to Bryce Hill of the institute, the budget relies on "shortsighted fixes and ignores structural problems" to cover rising costs of education, state pensions, and health benefits for government workers. Hill's written statement argued that "once again, taxpayers will pay the price."

The critique touches on a tension running through state-level digital advertising taxes broadly: whether raising revenue from advertising services creates pass-through effects on businesses and consumers. PPC Land has documented how small businesses have been warning Congress that state-level digital advertising taxes risk increasing costs, reducing campaign effectiveness, and limiting access to tools that smaller operators depend on - a coalition called Internet for Growth brought entrepreneurs to Capitol Hill as recently as May 12-13, 2026, to press that case with bipartisan lawmakers.

Context for the advertising industry

For the advertising community, SB 3019 is notable on several levels. The 10% rate on gross receipts from targeted advertising services is high compared to precedents elsewhere. Maryland's now-invalidated tax ranged from 2.5% to 10% depending on global revenue scale. Washington State applies its standard 6.5% sales tax rate. Illinois sets a flat 10% directly on gross receipts within the state for any provider exceeding the $1 million annual threshold.

The threshold itself - $1 million in cumulative gross receipts from targeted advertising services within Illinois over the previous 12 months - is notably low. It would capture not just large platforms but potentially mid-size advertising networks or technology providers with meaningful Illinois business. Small businesses lobbying Congress in May 2026raised exactly this concern: that compliance cost structures created by state-level advertising taxes tend to hit intermediary layers of the supply chain, with effects cascading outward even to operators nominally below thresholds.

The social media fee structure operates independently from the targeted advertising tax and applies to platforms based on user counts rather than revenue, creating a different compliance model. A platform with 1.2 million Illinois users would pay $165,000 plus 50 cents per user above 1 million - in that example, adding another $100,000 for a total of $265,000 per month.

On the prediction market side, bringing these platforms into the state's Sports Wagering Act framework rather than creating standalone legislation reflects a legislative choice to use existing infrastructure. The specifics of the tax rate and collection mechanism for prediction market transactions were not detailed in the bill status documents reviewed, though Bloomberg Tax's reporting confirms the structural decision to tax such platforms was confirmed in the final enrolled text.

The digital asset tax at 0.2% of transaction value, collected by brokers, is comparatively modest by rate - but applies at point-of-transaction, meaning high-frequency or high-volume traders and platforms could face meaningful aggregate liability.

What comes next

The bill passed both houses today and now awaits Gov. Pritzker's signature. Pritzker's own statement indicates he intends to sign. All three digital-economy levies - the targeted advertising tax, the social media platform fee, and the digital asset privilege tax - are scheduled to take effect January 1, 2027, giving businesses approximately seven months to prepare compliance frameworks.

For the ad tech and programmatic advertising industries, the core compliance question is definitional: what constitutes a "targeted advertising service" under Illinois law, and how does the gross receipts calculation work across campaigns that may serve users in multiple states simultaneously. The sourcing challenges are not new - Washington State's implementation of its advertising services tax in October 2025 exposed exactly these issues, with law firms noting that determining where digital advertising is "received" in a multi-state context involves contested interpretation.

Legal challenges are possible. Maryland's digital advertising tax was struck down as violating the dormant commerce clause and the federal Internet Tax Freedom Act. Illinois legislators may have sought to draft around those vulnerabilities, but the constitutional questions around state-level digital advertising taxes have not been resolved at the federal level - the US Chamber of Commerce's challenge to Maryland's law was proceeding in federal court before Maryland's state law was separately invalidated. Observers in the tax community will be watching whether similar challenges emerge in Illinois.

Timeline

Summary

Who - The Illinois General Assembly, led in the Senate by Sen. Celina Villanueva and in the House by Rep. Curtis J. Tarver II, passed SB 3019 on June 1, 2026. Gov. J.B. Pritzker indicated his intent to sign the bill. The Illinois Policy Institute and business groups opposed portions of the measure. Digital advertising providers, social media platforms, digital asset brokers, and prediction market operators are the primary entities affected.

What - SB 3019 creates the Targeted Advertising Services Tax Act, imposing a 10% levy on gross receipts from targeted advertising services in Illinois for providers exceeding $1 million in annual state revenue. It adds a graduated social media platform fee tied to Illinois user counts, a 0.2% digital asset privilege tax collected at the broker level, and incorporates prediction markets into Illinois's Sports Wagering Act tax framework. The bill also restricts corporate net operating loss deductions to $500,000 or 15% of net income during fiscal 2027. Combined, the new levies are projected to raise more than $800 million to support a $55.9 billion fiscal 2027 state budget.

When - The bill passed both chambers on June 1, 2026. The three digital economy taxes take effect January 1, 2027.

Where - Illinois. The taxes apply to targeted advertising services provided within the state, to social media platforms based on their Illinois user counts, and to digital asset transactions where the customer is located in Illinois.

Why - Illinois legislators engineered the revenue package to close a budget gap and support $55.9 billion in fiscal 2027 spending, covering education, state pensions, and government employee health benefits. Illinois Democrats, who hold substantial majorities in both chambers, used the digital economy as a new tax base, following precedents set by Maryland (since invalidated), Washington State, and other jurisdictions grappling with how to tax large technology platforms and digital services businesses operating across state lines.
