Let me start with the part of this lawsuit nobody has written about.
The complaint asks you to picture a man it calls Steve Doe. He lives in Austin, Texas. He spends some of his time in Chicago, and he uses a Chicago address to get his mail. So that is the address he put on his digital asset accounts.
One day, while he is in Austin, he buys a coffee using a debit card that spends stablecoins. He pays a friend back five dollars for a scone. Later he moves some governance tokens from his exchange account to his own wallet so he can vote in an online protocol vote, then moves them back for safekeeping.
He made no profit. He took no loss. He asked for nothing in Illinois, received nothing in Illinois, and paid nothing in Illinois. The only thing connecting any of it to this state is the mailing address on his account.
Under the new law, the lawsuit says, that address alone is enough. It presumes each of those events is an Illinois transaction. Each transfer and each act of storage counts separately, measured against the full value of the asset. And a company that fails to collect the tax on a five dollar scone repayment is looking at a Class 3 felony.
That is paragraphs 36 through 38 of a document filed in a Springfield courtroom on July 21.
What was filed, and by whom
The Chamber of Digital Commerce, which does business as The Digital Chamber, sued the State of Illinois on July 21, 2026. It is a Washington, D.C. trade group representing more than 250 companies in the blockchain industry.
A few details worth getting right, because a lot of the coverage got them wrong. The case was filed in the Circuit Court of Sangamon County, the Seventh Judicial Circuit. That is a state court in Springfield, not a federal court, and several national outlets reported otherwise. The defendants are David Harris, the Director of the Department of Revenue, and Kwame Raoul, the Attorney General, both sued in their official capacities. The filing runs 32 pages, raises six counts, and is verified under penalty by the Chamber’s CEO, Cody Carbone. It asks the court to declare the Digital Asset Tax Act void and to block it before it takes effect on January 1, 2027.
Two things I want to say plainly before going further.
The Illinois Bitcoin Council is not a party to this case. We did not file it nor are we funding it. I am reading it the same way you can, as a member of the public.
And a complaint is one side’s argument. It is written by lawyers to win. Nothing in it has been tested, answered, or decided. The State has not filed its response yet. Everything below is what the plaintiffs allege, and I have tried to be careful to say so.
With that said, this is the most detailed public account of what is wrong with this law that anyone has produced, and parts of it are worth your time.
The six counts, in plain English
The complaint groups into four ideas.
Fairness. Count I says the tax violates the Illinois Constitution’s Uniformity Clause, which requires that tax classes be reasonable and that everything inside a class be taxed the same way. The argument is that this law sorts by recordkeeping technology and nothing else. A Treasury bond and a tokenized Treasury bond are the same instrument. A dollar in a payment app and a dollar-denominated stablecoin are the same value. Moving money between your own two accounts at a brokerage and moving it between your own two wallets is the same act. In each pair, only the blockchain version gets taxed.
I wrote about the Uniformity Clause here on July 4, before this suit existed. The complaint makes the same argument with more machinery behind it.
Notice. Count II is due process under the Illinois Constitution, and it has three parts. The first is that the law is so vague it cannot be followed. The complaint’s list is blunt: the law does not define what property is taxed, who has to collect, what counts as one taxable event versus three, what “value” means or when it is measured, or how to tell where a customer is. Every one of those is unanswered, and getting the answer wrong is a felony.
The second part is the location rule. The law presumes your customer is in Illinois if any data points here, and puts the burden on the company to prove otherwise. The complaint says that is proving a negative on a network that has no fixed location to begin with.
The third part is the most striking thing in the filing, and I will come back to it.
Reach. Count IV says the tax fails all four parts of the test the Supreme Court uses for state taxes on interstate commerce. Count V says the same conduct violates federal due process, because a state can only tax where there is a real connection between the state and the thing being taxed. A mailing address, the complaint argues, is not that connection.
Federal law. Count VI says the tax is preempted by the Internet Tax Freedom Act, the 1998 law Congress made permanent in 2015, which bars states from taxing electronic commerce differently than the same commerce done another way. We wrote about ITFA last week. The complaint’s version of the argument is that blockchain commerce is electronic commerce in the ordinary meaning of the words, and that Illinois taxes it while taxing nothing comparable done through a bank.
Count III is separate and worth its own line. It says a Class 3 felony for failing to register or collect under a brand new and undefined tax is out of proportion to the offense, which the Illinois Constitution does not allow.
The two things I would remember
First, the math. Paragraph 44 says something no news story I have seen has picked up. If you hold Bitcoin with one broker and move it to another, the storage is taxed, the transfer is taxed, and the new storage is taxed again. Nothing was sold. Nothing changed hands. Nobody made a dollar. The complaint says each round of moving and holding between accounts you control yourself costs at least 0.4 to 0.6 percent of the asset, and there is no limit on how many times that can happen.
That is the arithmetic version of the point I made here on June 27 about moving money from your own right pocket to your own left. It is one thing to say the taxable event is incoherent. It is another to see the percentage.
Second, the collection problem. This is the substantive due process argument, and it is the sharpest thing in the document. The statute makes the broker liable for the tax, in the law’s words, “whether or not the tax has been collected.”
The complaint’s answer is that sometimes it cannot be collected. If a customer moves a token that cannot be split into fractions, and tokenized gold and tokenized bonds often cannot, there is no slice for the broker to hold back as tax. If a company’s only role is helping a customer recover a lost key, and it has no right to touch what is in the wallet, there is nothing for it to take the tax out of.
So the allegation is this: strict liability, enforced by a felony, for collecting something that in some cases is physically impossible to collect.
I have read a lot of criticism of this law over the last six weeks. That is the argument I had not seen before.
What the law says nothing about
Paragraphs 30 through 35 make a quieter point that matters if you actually use this technology.
Staking. Wrapping. Bridging between networks. Lending into a protocol. Providing liquidity. Consolidating your own wallets. All of these move assets around without selling them or handing beneficial ownership to anyone. All are ordinary. And the statute says nothing about whether any of them is taxable, how many taxable events each one creates, or whether a receipt token you get back is itself a second asset that gets taxed again.
The complaint’s line here is one I keep thinking about: these are legal questions, and software cannot answer them. No blockchain reports whether beneficial ownership changed. Somebody has to decide, and right now nobody has.
How this bill became law
Paragraph 39 fills in a piece of the story I had only seen secondhand.
Senate Bill 3019 started life as a narrow bill amending the Illinois Finance Authority Act. Its subject was agricultural financing. It had nothing to do with digital assets. A House floor amendment then replaced the entire text with the budget package, which carried a new article originally called the Digital Asset Privilege Tax Act, later renamed. The tax was never introduced as its own bill, never heard on its own, and never debated on its own.
The Chamber lays this out as background. Notably, it does not sue over it. There is no count in this complaint about how the law was passed.
Where the State has real answers
I would be doing you a disservice if I only gave you the plaintiffs’ side, so here is the other one, and some of it is strong.
Facial challenges filed before a law even takes effect are hard to win. Illinois courts start from the presumption that a statute is constitutional, and the party attacking it carries the load. The State will argue that this is not the moment to decide, because the Department has not written its rules yet and those rules could resolve much of what the complaint calls vague.
On uniformity, the State will argue that digital assets are genuinely different: newer, harder to trace, subject to their own consumer protection statute, and presenting enforcement problems that traditional brokerages do not. Courts give legislatures a lot of room to draw tax lines, and “we drew this line because this market is new and hard to police” is not a frivolous answer.
On the federal internet law, the State has the argument I flagged last week. That law bars taxing electronic commerce worse than the same commerce done another way. But if a digital asset only ever moves electronically, the State can argue there is no other way to compare it to.
On the felony count, I want to be careful, because I have seen people overstate this. Felony penalties are standard in Illinois tax law. Other tax acts carry them. The complaint’s argument is not that felonies are exotic; it is that this felony attaches to obligations nobody can currently define. That is a narrower claim, and a better one.
And there is a theory the Chamber did not raise at all. A Chicago law firm writing about the case last week noted that taxing the mere storage of property, measured by that property’s full value, might run into the Illinois Constitution’s limits on taxing personal property by value. I am not a lawyer and I am not going to tell you whether that argument works. I mention it because experienced counsel wrote 32 pages and chose not to include it, and that choice is itself information.
What this changes, and what it does not
It is tempting to read the headline and conclude the lawyers have this handled.
They do not, yet. Here is the actual state of things, from the complaint’s own pages.
The tax is still law. It still takes effect on January 1, 2027. No court has ruled on anything. The Department of Revenue, as paragraph 41 says, has adopted no rules and issued no guidance at all: not on what “value” means, not on what “storing” covers, not on when one blockchain operation is one taxable event or several. And House Bill 5798, which would repeal the Act outright, is still sitting there, as paragraph 40 notes.
So there are three ways this law changes. A court can strike it down. The General Assembly can repeal it. The Department can write rules that narrow it.
You have a seat at two of those three.
What you can do this week
Write to your own State Senator and Representative. Not to mine, and not to a general inbox. Legislators count letters from the people who can vote for them. You can find yours here: [ILGA FIND MY LEGISLATOR LINK].
Four sentences is enough. Something like:
I’m a constituent in [your town]. I’m writing about the Digital Asset Tax Act that takes effect January 1. [One sentence, in your own words, about why this affects you.] A repeal bill, House Bill 5798, is pending, and I’d ask you to look at it seriously or to support fixing the law’s undefined terms before felony penalties attach to them. Thank you for your time.
One note on HB 5798, because I want to be straight with you. It currently has a single sponsor and no bipartisan support. That is the gap. This is not a partisan law and it should not have a partisan fix, and a repeal or amendment that draws sponsors from both parties is far more likely to go anywhere than one that does not. If your legislator is a Democrat, that is not a reason to skip writing. It is the reason to write.
Join the list. [SUBSCRIBE LINK] When the Department of Revenue opens its rules for public comment, that window will be short and it will be the single best chance any of us has to make this law less bad. I would like to be able to tell you the day it opens.
I’m not a lawyer and this isn’t legal advice. Everything above about the lawsuit is what the plaintiffs allege, cited by paragraph so you can check me. The complaint is public and worth reading yourself. Corrections welcome.
