Illinois Crypto Transaction Tax Faces Broad Industry and DOJ Opposition in Court
A broad coalition including the U.S. Justice Department, the U.S. Chamber of Commerce, SIFMA and major crypto firms has filed briefs backing a lawsuit against Illinois' Digital Asset Tax Act. The state has agreed to pause the 0.2% levy until July 1, 2027, while the challenge proceeds in state court.

What the Coalition Filed
A group of federal and industry parties has filed briefs in Illinois state court supporting a challenge to the Digital Asset Tax Act, according to reporting from Decrypt. The Justice Department filed a statement of interest on Nov. 6 calling the law vague and discriminatory, arguing it singles out crypto for treatment no other asset faces. The lawsuit itself was brought by the Crypto Council for Innovation and the Blockchain Association, which are asking a judge to strike the law down and permanently block enforcement.
The U.S. Chamber of Commerce and the Securities Industry and Financial Markets Association filed an amicus brief warning that the tax reaches beyond crypto-native platforms into traditional banks, custodians and advisers that now offer digital asset products. A separate Nov. 11 brief was led by the DeFi Education Fund, Andreessen Horowitz, Paradigm and Uniswap, with support from Aave Labs, Chainlink Labs, Phantom, Jito Labs, Multicoin Capital and others.
How the Tax Is Designed
The law imposes a 0.2% levy on the full value of a digital asset each time an Illinois customer trades, transfers or stores it through a broker, even where there is no sale, gain or change in ownership. Critics point out that Illinois applies no comparable tax to dollars, gold, stocks or other assets, and that no other state has a similar measure.
The industry filings argue the statute's definitions are broad enough to reach software developers and decentralized protocols that hold no customer funds and cannot identify users or determine where a transaction took place. The Blockchain Association and CCI said in a joint statement that the tax is "unclear, discriminatory, unconstitutional, and harmful to the future of finance."
Figures and Where Sources Diverge
The Decrypt piece cites an estimated 2.64 million Illinois residents holding digital assets, the fifth-highest total of any state. CoinDesk's coverage characterizes the opposition in broader terms, reporting that the industry told the court the tax cannot be enforced as written, but it does not put a comparable figure on the number of affected holders. The two accounts also frame the scope of the dispute differently: CoinDesk emphasizes enforceability, while Decrypt emphasizes the breadth of the coalition and the constitutional and federal-policy arguments.
Timeline and Status
The challenge dates to August. Illinois agreed in October to pause enforcement of the tax until July 1, 2027, which gives the court time to rule before the law takes effect. No ruling has been reported yet.
Why It Matters
For Traders
The tax is paused until July 1, 2027, so no near-term transaction cost applies, but court filings and any preliminary ruling could move sentiment around Illinois-based trading activity.
For Investors
A federal statement of interest opposing a state crypto tax signals that the regulatory fight over digital asset taxation is spreading beyond the SEC and CFTC into state legislatures.
For Builders
Broad statutory definitions that could reach non-custodial protocols and developers create compliance uncertainty, so teams serving Illinois users should track the case closely.
