The first major legal challenge to Illinois’ newly enacted Digital Asset Tax Act has arrived.
On July 21, 2026, the Chamber of Digital Commerce d/b/a The Digital Chamber filed a lawsuit in the Circuit Court of Sangamon County seeking to invalidate Illinois’ controversial digital asset tax before it takes effect on January 1, 2027. The suit names David Harris, Director of the Illinois Department of Revenue, and Kwame Raoul, Illinois Attorney General, as defendants and seeks both declaratory and injunctive relief preventing enforcement of the law.
Background: Illinois’ New Digital Asset Tax
A Illinois recently became the first state in the nation to adopt a standalone tax specifically targeting certain digital asset activities.
The Digital Asset Tax Act, enacted as part of Public Act 104-0468, imposes a 0.2% tax on what the statute defines as “digital asset business activity,” including the exchange, transfer, or storage of digital assets by customers in Illinois. The law was signed by Governor Pritzker on June 16, 2026, and is scheduled to become effective January 1, 2027. Notably, the tax is to be administered by the Secretary of State, not the Department of Revenue.
The legislation has generated significant debate within the blockchain, cryptocurrency, and fintech industries because it taxes activities involving blockchain-based assets while leaving many traditional financial transactions outside its scope. According to the complaint, the tax applies not only to cryptocurrencies such as Bitcoin and Ether, but also potentially to stablecoins and tokenized versions of traditional financial assets.
What the Lawsuit Alleges
The lawsuit presents an unusually broad attack on the statute, arguing that the Digital Asset Tax Act is unconstitutional under both Illinois and federal law.
At the center of the complaint is the argument that Illinois is taxing a method of recordkeeping rather than a distinct category of property. The plaintiff contends that economically identical assets receive different tax treatment solely because one version is recorded and transferred using blockchain technology. For example, the complaint contrasts traditional Treasury securities, bank deposits, and securities accounts with tokenized versions of those same assets that utilize blockchain infrastructure.
The plaintiff characterizes the law as the first state tax in the country to impose materially different tax consequences based on the technological infrastructure used to record ownership rather than the underlying economics of the transaction.
The Six Counts
The complaint contains six separate causes of action:
Count I: Illinois Uniformity Clause
The plaintiff argues that the tax violates Illinois’ constitutional requirement that non-property taxes apply uniformly. According to the complaint, there is no meaningful distinction between traditional assets and tokenized assets sufficient to justify different tax treatment.
Count II: Illinois Due Process
The lawsuit alleges the statute is unconstitutionally vague because it fails to clearly define key terms and concepts, including valuation methods, taxable events, and geographic nexus standards. The complaint also challenges the law’s presumption that certain activities are connected to Illinois customers. The Due Process challenge also asserts unconstitutional presumption, and substantive due process.
Count III: Illinois Proportionate Penalties
The plaintiff contends that making violations punishable as a Class 3 felony is disproportionate given the nature of the underlying conduct and the alleged uncertainty in the statute. This is brought also under Article I of the Illinois Constitution.
Count IV: Dormant Commerce Clause
The complaint argues that blockchain transactions occur on decentralized networks without a fixed geographic location and that Illinois is attempting to tax interstate commerce in a manner prohibited by the U.S. Constitution. The four components of the Complete Auto Transit dormant commerce clause analysis are articulated in the Complaint: 1) no substantial nexus; 2) no fair apportionment; 3) discrimination against interstate commerce; and 4) no fair relation to services.
Count V: Federal Due Process
The plaintiff also alleges violations of the Due Process Clause of the Fourteenth Amendment, asserting insufficient connection between Illinois and certain transactions the statute purports to tax.
Count VI: Internet Tax Freedom Act
One of the more interesting claims is that the statute is preempted by the federal Internet Tax Freedom Act because it allegedly imposes a discriminatory tax on electronic commerce. The plaintiff argues that transactions conducted through blockchain technology are taxed while economically similar transactions conducted through traditional financial systems are not.
The Complaint asserts that a tax is discriminatory under the ITFA if it 1) is not generally imposed and legally collectible on transactions involving similar property, goods, services, or information accomplished through other means; 2) is not imposed at the same rate on such transactions, or 3) imposes a collection or payment obligation on a different person than for such transactions. The ultimate question on this claim, and whether it withstands the Department’s Motion to Dismiss will likely come down to whether these are transactions are similar enough at prong one.
Why This Case Matters
Although the tax itself is relatively small at 0.2 percent, the litigation could have consequences far beyond Illinois.
If upheld, the Digital Asset Tax Act could provide a framework for other states seeking new revenue sources from digital assets and blockchain-based financial infrastructure. If struck down, the decision could establish important limits on how states may tax digital asset transactions and emerging financial technologies.
The case also arrives at a pivotal moment as traditional financial institutions increasingly explore tokenization, stablecoins, blockchain settlement systems, and other digital asset applications. The lawsuit repeatedly emphasizes that tokenization is becoming a mainstream financial infrastructure tool rather than a niche cryptocurrency innovation.
For now, the lawsuit is in its earliest stages. The plaintiff seeks a declaration that the Digital Asset Tax Act is unconstitutional and a preliminary and permanent injunction preventing Illinois from implementing or enforcing the law before its January 1, 2027 effective date. Whether Illinois can become the first state to successfully impose a dedicated digital asset transaction tax will now be decided in the courts.
