"Illinois has enacted a first-in-the-nation tax that unfairly singles out digital commerce, fragments a national market, and exposes companies and ordinary Illinoisans to severe penalties — including felony liability for companies — for guessing wrong about an indeterminate statute." — Summer Mersinger, CEO, Blockchain Association
Illinois's Digital Asset Tax Act, signed June 16, 2026, as part of the state's $55.9 billion budget (SB 3019), now faces three separate legal challenges filed between July and September 2026. The law imposes a 0.2% privilege tax on covered digital asset transactions beginning January 1, 2027 — the first transaction-level crypto tax enacted by any U.S. state. The state projects approximately $60 million in annual revenue from the levy.
On September 9, the Crypto Council for Innovation (CCI) and Blockchain Association escalated the fight by filing a motion for preliminary injunction in the Circuit Court of Sangamon County, asking the court to block enforcement before the January 1 effective date. The filing follows an initial lawsuit by the same groups on August 21 and a prior challenge brought by The Digital Chamber on July 21. Combined, the three actions raise seven distinct constitutional and federal preemption claims. Illinois has approximately 2.64 million crypto holders — the fifth-largest state concentration in the U.S. — all of whom face direct exposure.
The Digital Asset Tax Act imposes a 0.2% privilege tax on the value of digital asset business activity received by Illinois customers. Unlike capital gains taxes, the levy is not contingent on profit. It applies to all covered transactions — including losing trades, transfers between a user's own accounts, custody, and wallet services.
Key structural features:
The $100,000 remote-broker threshold is low enough to capture virtually every major centralized exchange serving Illinois customers, including Coinbase, Kraken, and Robinhood. The tax applies to transactions regardless of whether the user profits, distinguishing it from every other form of U.S. securities or commodity taxation at the state level.
According to analysis by the Illinois Policy Institute, a single covered act — such as moving crypto from one exchange to a personal wallet, then to another exchange — could be taxed multiple times, pushing the effective rate well above the nominal 0.2%.
SB 3019 began as a two-page agricultural finance bill introduced in January 2026. On May 31, the final day of the Illinois General Assembly's session, amendments replaced the bill's original contents with a 1,624-page package covering gambling, vehicle regulations, and the Digital Asset Tax Act. Both chambers passed it within 24 hours.
Plaintiffs in all three lawsuits allege this process violated Illinois's constitutional Three-Readings Rule, which requires that a bill be read on three different days in each chamber before passage. They also cite the Single-Subject Rule, which prohibits omnibus legislation that bundles unrelated subjects into a single vote.
According to Bloomberg Tax, the legislative process represents "a first-of-its-kind cryptocurrency transaction tax" pushed through under conditions that multiple legal observers describe as procedurally vulnerable.
The legal assault on the Digital Asset Tax Act has arrived in three waves:
Wave 1: The Digital Chamber (July 21, 2026) The Digital Chamber filed the first challenge in Sangamon County Circuit Court, arguing the tax violates the U.S. Constitution, the Illinois Constitution, and the Internet Tax Freedom Act. According to CoinDesk, the suit alleges that "no one should be taxed differently because of how ownership is recorded or transferred."
Wave 2: CCI and Blockchain Association Original Suit (August 21, 2026) The Crypto Council for Innovation and Blockchain Association filed a second lawsuit raising seven distinct claims under federal and Illinois law: violations of the Internet Tax Freedom Act, the dormant Commerce Clause, federal and state due process protections, and the Illinois Constitution's Uniformity Clause, along with the Three-Readings and Single-Subject procedural challenges.
Wave 3: CCI and Blockchain Association Preliminary Injunction (September 9, 2026) The same groups filed a motion for preliminary injunction to block enforcement before the January 1, 2027 effective date. CCI CEO Ji Hun Kim stated that "companies are being asked to spend millions to build systems for a tax that violates their Constitutional rights without answers to basic questions about what is taxed and when."
The Blockchain Association argued the state "loses very little by waiting" since it cannot collect any revenue during active litigation, while companies face irreparable harm from building compliance infrastructure for a potentially unconstitutional law.
The Internet Tax Freedom Act (ITFA), made permanent in 2016, prohibits state and local governments from imposing taxes that discriminate against electronic commerce. The plaintiffs' core federal preemption argument is straightforward: Illinois taxes digital asset transactions conducted over the internet while imposing no equivalent transaction tax on traditional securities trades executed through the same brokers.
According to analysis by Jones Day, the tax structure creates a direct comparison problem. A customer who buys $10,000 in stock through a brokerage in Illinois pays zero state transaction tax. A customer who buys $10,000 in bitcoin through the same brokerage owes $20. The differential treatment is the exact scenario ITFA was designed to prevent.
Reed Smith LLP noted in its analysis that the ITFA argument may be the plaintiffs' strongest claim, given that courts have historically interpreted the Act's anti-discrimination provisions broadly. A 2023 New York appellate decision struck down a state tax under similar ITFA reasoning.
The state has not yet filed a public response addressing the ITFA claims.
The operational requirements extend well beyond the 0.2% rate. According to BPM, brokers must:
According to American Banker, the compliance infrastructure requirements represent a significant cost for platforms that must build Illinois-specific tax collection, sourcing, and valuation systems. The publication noted that "a single act could be taxed several times over, pushing the effective rate well above 0.2%."
For high-frequency traders or DeFi protocols routing through covered brokers, the cumulative impact of transaction-level taxation on gross value — not profit — represents a structural disincentive to operate in or serve Illinois. The tax applies to custody and wallet services in addition to trades, meaning that simply holding digital assets through a covered broker generates a taxable event.
On June 22, 2026 — six days after Governor Pritzker signed SB 3019 — Illinois Representative John Cabello introduced House Bill 5798 to repeal the Digital Asset Tax Act in its entirety. According to The Center Square, Cabello characterized the tax as "punitive."
HB 5798 was referred to the House Rules Committee, where it has remained without a hearing. The Illinois General Assembly is in recess and does not reconvene for its next session until January 2027, meaning the repeal effort and the tax's effective date arrive on essentially the same timeline.
The existence of an immediate repeal bill from within the same legislature that passed SB 3019 underscores the degree to which the tax's inclusion in the omnibus budget package bypassed standard legislative deliberation.
New York Assemblymember Phil Steck introduced Assembly Bill 8966, which would impose an identical 0.2% excise tax on digital asset transactions, including sales and transfers. Steck projects the tax would generate $158 million annually, with revenue earmarked for substance abuse prevention programs in upstate New York.
The bill was referred to the Ways and Means Committee. If the Illinois law survives legal challenge, it establishes precedent for other high-population states to adopt similar transaction-level levies. New York's 4.66 million crypto holders represent an even larger tax base than Illinois's 2.64 million.
Combined, Illinois and New York account for approximately 7.3 million crypto holders. A 0.2% transaction tax applied across both states would represent the first meaningful state-level friction cost on digital asset activity in the United States.
The Illinois Digital Asset Tax Act represents the first attempt by a U.S. state to impose a transaction-level tax specifically targeting digital assets. The law's survival is uncertain. Three industry groups have filed separate challenges raising overlapping but distinct constitutional and federal preemption claims. The September 9 preliminary injunction motion aims to prevent enforcement before the January 1, 2027 effective date, buying time for the underlying constitutional questions to be adjudicated.
The economic logic of the tax is atypical. It taxes activity, not income. It captures losing trades and self-transfers. It requires brokers to build state-specific compliance infrastructure for a $60 million annual revenue target — a figure that may not justify the administrative cost imposed on the industry or the legal cost imposed on the state.
The outcome in Sangamon County Circuit Court will set precedent beyond Illinois. New York's pending AB 8966 demonstrates that other states are watching. If the ITFA preemption argument fails and the tax stands, the 0.2% transaction-tax model becomes available to every state legislature in the country. If it falls, the ruling constrains a potential new category of state-level digital asset taxation before it proliferates.
Illinois has not yet filed a public response to any of the three lawsuits. The next procedural milestone is the court's decision on the preliminary injunction motion, expected before year-end.
