The Crypto Council for Innovation (CCI) and the Blockchain Association (BA) have filed a motion for a preliminary injunction in the Circuit Court of Sangamon County, Illinois, seeking to block the enforcement of a 0.2% tax on cryptocurrency transactions. The trade groups argue that digital asset firms face irreparable harm from being forced to spend millions building compliance systems for a tax they contend violates constitutional rights, with criminal penalties attached. The measure is scheduled to take effect in January 2027.

Illinois Governor JB Pritzker signed the legislation as a "privilege tax" in June as part of the state’s fiscal year 2027 budget, requiring taxation based on transaction volume rather than income. This makes Illinois the first state in the nation to single out crypto transactions in this manner. The CCI and BA previously filed a lawsuit last month challenging the tax under the US Constitution, state constitution, due process laws, and the federal Internet Tax Freedom Act. The Digital Chamber also filed a similar suit days earlier.
