"This tax singles out digital assets for uniquely punitive treatment based on the underlying technology rather than the substance of the transaction itself." — Ji Kim, Head of Policy, Crypto Council for Innovation
Illinois became the first U.S. state to impose a transaction-level tax on digital asset activity when Governor J.B. Pritzker signed Senate Bill 3019 on June 16, 2026. The Digital Asset Tax Act (DATA) levies a 0.2% privilege tax on every exchange, transfer, or storage event handled by a broker connected to Illinois — regardless of whether the underlying trade generates a profit or a loss. The tax takes effect January 1, 2027, and is projected to raise approximately $60 million annually, or roughly 0.1% of Illinois's $56 billion state budget.
Two separate lawsuits now challenge the law's constitutionality. The Digital Chamber filed the first complaint on July 21, 2026, in the Circuit Court of Sangamon County. The Blockchain Association and Crypto Council for Innovation filed a second suit on August 21, 2026, in the same court. Both seek declaratory and injunctive relief. No court has yet blocked enforcement. A repeal bill, HB 5798, was introduced on June 22 but has not advanced. No other U.S. state has enacted a comparable transaction-level digital asset tax.
DATA imposes a 0.2% tax on the value of "digital asset business activity," defined as any single occurrence of exchanging, transferring, or storing a digital asset as part of a business or on behalf of a customer. The statute references the 2025 Digital Asset and Consumer Protection Act (DACPA) for its definition of "digital asset" — a digital representation of value used as a medium of exchange — but excludes gaming tokens and utility NFTs with "substantial value beyond mere digital existence."
Three categories of activity trigger the tax:
The tax base is measured against the gross value of the underlying digital asset at the time of the event. This means a $10,000 Bitcoin swap incurs a $20 tax liability whether the trader earns $5,000 or loses $5,000 on the position, according to analysis by Forbes and Jones Day. The statute does not define "value," creating what legal analysts describe as significant computational ambiguity.
The law was inserted into Illinois's broader $56 billion fiscal year 2027 budget package. According to the Illinois Policy Institute, the budget included more than $800 million in tax increases; DATA was one of several revenue provisions added during late-stage negotiations.
The tax falls on "digital asset brokers" — entities that facilitate exchange, transfer, or custody of digital assets. A broker must register with the Illinois Department of Revenue if it conducts any digital asset transaction with an Illinois customer. A separate $100,000 gross-receipts threshold triggers the obligation to collect and remit the tax.
According to Jones Day analysis, Illinois presumes all receipts are in-state absent documentary evidence proving otherwise, shifting the compliance burden to brokers to demonstrate that a customer or transaction lacks an Illinois connection.
The enforcement regime carries severe penalties. Noncompliance — including failure to file returns, failure to register, or failure to maintain records — is classified as a Class 3 felony under Illinois law. According to the complaint filed by the Digital Chamber, this carries potential prison sentences of two to five years and fines up to $25,000.
The Digital Chamber's complaint argues this penalty structure is "grossly disproportionate to the seriousness of the offense," noting that DATA imposes felony-level criminal liability for noncompliance with a tax statute that leaves critical terms — including taxable property, taxpayer, taxable event, measure of tax, and geographic nexus — undefined.
Lawsuit 1 — The Digital Chamber v. Harris et al. Filed: July 21, 2026 Court: Circuit Court of Sangamon County, Seventh Judicial Circuit Defendants: Illinois Department of Revenue Director David Harris, Attorney General Kwame Raoul Relief sought: Declaratory judgment voiding the Act; preliminary and permanent injunctive relief
The Digital Chamber, a nonprofit representing more than 250 blockchain industry participants, filed a 32-page verified complaint seeking to block DATA before its January 2027 effective date.
Lawsuit 2 — Blockchain Association & CCI v. Harris et al. Filed: August 21, 2026 Court: Circuit Court of Sangamon County Defendants: Director Harris, AG Raoul, Sangamon County State's Attorney John Milhiser Relief sought: Same declaratory and injunctive relief
Summer Mersinger, CEO of the Blockchain Association, stated: "Illinois cannot impose a novel tax regime that discriminates against digital commerce, creates uncertainty for consumers and businesses, and threatens to fragment a rapidly growing national market."
As of August 25, 2026, neither court has issued a temporary restraining order or preliminary injunction.
Both complaints raise overlapping constitutional claims across federal and state law:
The complaints argue DATA fails all four prongs of the Complete Auto Transit v. Brady test:
Both suits allege DATA violates the federal Internet Tax Freedom Act (ITFA) by imposing a discriminatory tax on electronic commerce. The argument: digital asset exchange, transfer, and custody conducted online is treated differently from comparable transactions involving stocks, cash, or gold conducted through traditional channels. ITFA prohibits state taxes that discriminate against electronic commerce.
The Digital Chamber's complaint argues DATA violates the Illinois Constitution's Uniformity Clause because it classifies solely by recordkeeping technology. The tax targets assets recorded on distributed ledgers while exempting functionally identical financial instruments tracked on centralized databases.
The Digital Chamber alleges the statute is void for vagueness because it fails to define critical terms — including "value," the precise scope of "storage," and the geographic boundaries of taxable events — yet imposes felony-level criminal penalties for noncompliance.
Both complaints challenge the Class 3 felony classification for noncompliance as disproportionate to the nature of the offense, violating the Illinois Constitution's proportionate penalties clause.
Chicago houses a concentration of crypto-native firms, including Jump Crypto — the digital asset arm of Chicago-based Jump Trading — and Bitnomial, operator of the first U.S. leveraged retail spot crypto exchange. Both firms have publicly expressed concern over DATA's impact on operations, according to reporting by Bitcoin Magazine and CPA Practice Advisor.
The Crypto Council for Innovation characterized DATA as "the most punitive digital asset tax in the country," arguing it creates "an unprecedented tax regime that disproportionately burdens Illinois residents." The Illinois Blockchain Association and Digital Chamber jointly described the law as "a punitive, discriminatory measure rushed through in the dark of night that will drive businesses and jobs to competing states."
The practical concern is straightforward: if high-volume trading firms and custodians face a 0.2% levy on every transaction — applied to gross value, not profit — the economics of operating in Illinois deteriorate relative to the 49 states that impose no such tax. For a firm processing $1 billion in annual crypto transaction volume, DATA would generate approximately $2 million in additional state tax liability, a cost that does not exist in any other jurisdiction.
According to the Illinois Policy Institute, the state's projected $60 million annual haul from DATA assumes current levels of crypto business activity persist. If firms reduce Illinois-connected operations or relocate, that projection becomes aspirational.
No other U.S. state has enacted a transaction-based digital asset tax as of August 2026. The policy landscape trends in the opposite direction:
Illinois's approach is an outlier. Traditional financial transaction taxes at the state level — such as stock transfer taxes — have largely been repealed or reduced over the past half-century. New York ended its stock transfer tax in 1981 (though the tax technically persists with a 100% rebate). Illinois is moving in the opposite direction by creating a new transaction-level tax category that applies exclusively to digital assets.
At the federal level, the CLARITY Act — currently facing a September 15, 2026 Senate cloture vote — would establish a national framework for digital asset classification. If enacted, it could preempt state-level approaches like DATA, though the bill's text does not explicitly address state taxation.
State Representative John Cabello (R-Machesney Park) filed House Bill 5798 on June 22, 2026 — six days after Pritzker signed DATA into law. The bill would repeal the Digital Asset Tax Act entirely. As of August 25, the Illinois legislature remains out of session for the remainder of the year. The bill has not advanced through committee.
A line-item veto by Governor Pritzker remains theoretically possible during the fall veto session but appears unlikely given his administration's role in including DATA in the budget package.
The practical path to blocking DATA before January 1, 2027, runs through the Sangamon County courts. If either lawsuit secures a preliminary injunction, enforcement would be stayed pending resolution. Without judicial intervention, brokers must begin registering and collecting the tax by year-end.
DATA represents a fiscal experiment with no U.S. precedent. Illinois is betting that $60 million in projected revenue outweighs the risk of driving a concentrated cluster of crypto firms — and their associated jobs, tax revenue, and economic activity — to jurisdictions that impose no such burden. The constitutional challenges are substantive; the Dormant Commerce Clause arguments, in particular, strike at a fundamental tension between state taxing authority and the borderless architecture of blockchain networks. Whether a Sangamon County judge agrees will likely determine whether DATA takes effect on schedule — and whether other states view Illinois as a template or a cautionary tale.
