Two crypto industry groups filed a lawsuit in Illinois state court on August 21, hoping to stop the state's Digital Asset Tax Act before it takes effect. The Blockchain Association and the Crypto Council for Innovation are arguing that the law, which would impose a 0.2% tax on the value of digital asset transactions starting January 1, 2027, is unconstitutional. The suit says the tax runs into the dormant Commerce Clause, the federal Internet Tax Freedom Act, and state due process protections.
What the tax would hit
The tax applies to the value of each digital asset transaction, not to gains or income. That's a broad net. Every trade, every transfer, every DeFi routing would be taxed, even if the person lost money. Exchanges, high-frequency trading, institutional investors, and everyday payments would all be caught. The industry groups argue that's a direct tax on the act of using crypto, something no state has done before at this level.
The legal arguments
The dormant Commerce Clause is the core of the challenge. It says states can't burden interstate commerce, and crypto transactions rarely stay inside one border. The groups also cite the federal Internet Tax Freedom Act, which limits state taxes on internet-related services. The due process argument is more practical: Illinois hasn't shown enough connection to the transactions to justify taxing them.
By filing in state court, the groups are asking an Illinois judge to apply both federal and state rules. The question is straightforward: does the tax hold up? The court hasn't ruled, so the law is still on the books but not yet in effect.
If the law stands, other states could copy the template. A 0.2% per-transaction tax is easy to replicate, and states are always looking for new revenue. A successful challenge would likely stop that momentum. The two groups aren't asking for money—they're asking for a ruling that blocks the tax before exchanges have to build compliance systems for a charge that might not survive.
The next step is a court decision on whether to put the law on hold. No hearing is scheduled yet. The industry is watching closely, because this isn't just about Illinois. It's about whether any state can tax every crypto transaction that crosses its borders.
