Crypto advocacy groups oppose Illinois digital asset tax in court

The Crypto Council for Innovation (CCI) and Blockchain Association (BA) filed a lawsuit against Illinois officials regarding the state’s 0.2% tax on cryptocurrency, expected to be enforced starting in January 2027. 

In a lawsuit filed Friday in the Circuit Court of the Seventh Judicial Circuit for Sangamon County, lawyers for the two crypto advocacy groups challenged Illinois’ digital asset tax on the grounds it violated the US Constitution, the state’s constitution, federal and state due process laws and the federal Internet Tax Freedom Act. Illinois Governor JB Pritzker signed the measure into law as a “privilege tax” in June as part of the state’s fiscal year 2027 budget, requiring crypto users to be taxed as applied to transaction volume rather than income.

On the due process claim, CCI and BA argued that the tax was “unconstitutionally vague” by placing the burden on residents and brokers “under the threat of serious civil and criminal penalties” to determine what and how such assets were taxed. Notably, the crypto organizations’ arguments under the US Constitution were based on alleged violations of the Commerce Clause covering interstate commerce, claiming that the state tax “creat[ed] the specter of duplicative taxation.”
