Illinois has enacted a 0.2% digital asset tax, but it is already facing a fresh legal challenge before the levy takes effect on Jan. 1, 2027.
- 0.2% digital asset levy set to begin Jan. 1, 2027
- Blockchain Association and Crypto Council for Innovation sue Illinois officials
- Challenge targets the Digital Asset Tax Act as unconstitutional and too vague
- Tax applies to broker activity involving exchanges, transfers, or storage of digital assets
The Blockchain Association and the Crypto Council for Innovation filed suit in Sangamon County Circuit Court to block Illinois from enforcing the Digital Asset Tax Act. Their complaint asks for declaratory and injunctive relief, which in plain English means a court ruling that the law is invalid and an order stopping the state from enforcing it.

The tax was signed into law by Governor JB Pritzker as part of Illinois’ $55.9 billion fiscal 2027 budget and became Public Act 104-468 on June 16. The state describes it as a 0.2% “privilege tax” on digital asset business activity tied to covered brokers. The measure is also covered in Illinois Digital Asset and Advertising Tax Changes in 2027.
That is the first thing to understand: this is not a simple capital gains tax. Under the law’s structure, the levy applies when a broker exchanges, transfers, or stores digital assets for an Illinois customer. The tax is triggered by the activity itself, not just by whether someone sells at a profit.
That matters because the complaint says the law could hit customers even if they do not sell, do not transfer ownership, and do not realize a gain. If that holds up in court, the state would be taxing a crypto transaction flow, not just a taxable investment outcome. That is a very different animal.
Summer Mersinger, CEO of the Blockchain Association and a former CFTC member, put it bluntly:
“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.”
The complaint says the law violates the U.S. Constitution, the Illinois Constitution, and the federal Internet Tax Freedom Act. Those are not just legal buzzwords. They point to three core problems the plaintiffs want the court to address.
The Commerce Clause is the part of the U.S. Constitution that limits state laws that burden interstate commerce. The plaintiffs argue Illinois is trying to reach beyond its borders by taxing broker activity involving out-of-state firms and multi-state customers.
The due process argument is about fair notice. If a law is too vague for brokers and customers to know when tax obligations begin, end, or stack up, that can become a constitutional problem fast.
The Illinois Uniformity Clause requires taxes to be applied uniformly. The plaintiffs say crypto is being singled out for treatment that does not match how traditional assets are taxed. The relevant state framework can be found in the Illinois Compiled Statutes (ILCS).
The Internet Tax Freedom Act is a federal law meant to prevent discriminatory taxes on electronic commerce. If Illinois is effectively imposing a special burden on digital asset activity while not taxing similar non-digital financial activity the same way, that becomes a live legal issue.
Illinois’ compliance rules are no joke either. Covered brokers must register with the Illinois Department of Revenue, collect the tax as a separate charge, keep transaction records, and file monthly returns. If the broker does not collect the levy, the customer is supposed to assess and pay it by the 20th day of the following month.
For businesses, that means new reporting systems, new tax logic, and new headaches. A centralized exchange or custodian would need to determine whether a customer falls under the law, calculate the levy, separate it from the transaction, and keep records long enough to satisfy the state. That is exactly the sort of operational mess crypto firms have been warning about for years.
According to BDO USA, some out-of-state brokers can also be pulled into the law if they receive at least $100, 000 from Illinois customers over a 12-month period. That is where the interstate commerce fight gets sharper. Once a state starts reaching into businesses with no physical presence in the state, the legal questions get messy very quickly.
Illinois’ budget package also included other digital-business taxes, including a targeted advertising services tax and a social media platform fee. That suggests a broader push to tax online and digital business models, not just crypto. Whether that strategy survives legal scrutiny is another matter.
The court fight is the second industry challenge to the tax. In July, the Digital Chamber filed a separate lawsuit in the same state court asking for the law to be declared void and unenforceable. A related report on the challenge is here: llinois 0.2% crypto tax faces new industry lawsuit. When multiple trade groups move against the same statute before it even takes effect, that is usually a sign the law landed with a thud in the industry and raised a lot of legal questions.
The plaintiffs also argue that the legislative process was rushed. They say Senate Bill 3019 began in January as a two-page proposal dealing with loans for agricultural property, then grew through amendments into a 1, 624-page package, with the digital asset provisions taking up fewer than 20 pages. They further say House and Senate committees gave the public about an hour or less of notice before hearings, and that both chambers passed the rewritten bill within 24 hours. Those are serious claims, and if the court views them as part of a broader pattern, they could add weight to the challenge.
There is a simple reason this fight matters beyond Illinois: if the state gets away with a crypto-specific activity tax like this, other states may decide to copy the model. If the law is blocked, lawmakers elsewhere may think twice before trying to turn digital assets into a special tax target.
Why the law is drawing so much heat
The strongest criticism is not that crypto should never be taxed. It already is taxed in plenty of ways. The issue is whether Illinois has built a tax that treats digital assets differently from stocks, bonds, or other financial instruments without enough legal justification.
Miles Jennings, general counsel and head of policy at a16z Crypto, said in June that no comparable state financial transaction tax applies to stocks, bonds, or derivatives. That comparison cuts to the core of the dispute: if the state is singling out one asset class for a special levy, it needs to explain why that treatment is fair, uniform, and constitutional.
The complaint also says the law is unconstitutionally vague. That matters because vague tax rules do not just annoy compliance teams, they can create real legal risk. A broker that gets the definition wrong could face penalties, and the complaint says violations could expose a broker to felony prosecution. The research materials confirm felony exposure, though not the exact class of felony alleged in the complaint.
There is also the question of cumulative taxation. If a digital asset can be taxed at different steps as it moves through exchange, transfer, or custody functions, the nominal 0.2% rate may not stay so small in practice. Multiple touches can stack up. That is the sort of detail lawmakers love to underplay and businesses love to litigate.
Illinois will likely argue that it is simply taxing business activity connected to its residents and its market, and that crypto firms using the state’s financial infrastructure should contribute like everyone else. That is a defensible political argument. It is not the same thing as a winning legal argument, especially if the law reaches beyond Illinois in ways that courts see as overbroad or discriminatory.
Michael Saylor also slammed the move, calling it a “Big Mistake.” He is not exactly known for holding back, but his reaction fits the broader mood: crypto businesses are increasingly treating state-level digital-asset taxes as a line in the sand, not a minor policy tweak.
For now, Illinois has a law on the books, not a settled tax regime. The court will have to decide whether the Digital Asset Tax Act is a legitimate revenue measure or a state-level overreach that runs into constitutional limits.
That scrutiny is part of a wider policy pattern, and it is not limited to taxes. The same industry circles have been pushing back on heavy-handed crypto rules elsewhere, including Blockchain Association Slams Senate Over Stablecoin Yield, Blockchain Association Sues IRS Over DeFi Broker Rules, and the broader clash captured in Crypto vs. Banks: Stablecoin Regulations Threaten.
Key questions and takeaways
-
What did Illinois do?
The state enacted a 0.2% digital asset tax as part of its fiscal 2027 budget. It is set to take effect on Jan. 1, 2027, unless the legal challenge stops it or changes its enforcement.
-
Who is suing?
The Blockchain Association and the Crypto Council for Innovation filed the complaint in Sangamon County Circuit Court against Illinois officials. A parallel challenge was also reported by Crypto advocates join in suing Illinois over digital asset.
-
What activity is taxed?
The law targets broker activity involving digital assets, including exchanging, transferring, and storing them. It is a transaction-style levy, not a standard tax on profits.
-
Why do critics say the law is a problem?
They argue it is discriminatory, vague, and unconstitutional under federal and state law. Their main concerns are interstate commerce, due process, and unequal treatment of digital assets.
-
Does this affect out-of-state firms?
Yes, according to BDO USA, some out-of-state brokers can be covered if they receive at least $100, 000 from Illinois customers over a 12-month period.
-
Why does this matter outside Illinois?
If Illinois’ law survives, other states may try similar crypto-specific taxes. If it fails, that could discourage copycat efforts and strengthen the case against singling out digital assets for special treatment.
Illinois has opened a legal front that touches crypto policy, state taxation, and the limits of what a state can demand from digital commerce. The outcome will matter far beyond one budget line item.
