Everyday crypto users face monthly tax bills on total asset value if covered brokers fail to collect under new Illinois rules

Illinois’s 0.2% digital asset tax, scheduled to start Jan. 1, 2027, now faces another industry complaint as brokers prepare for a levy tied to the value of customer assets rather than their gains or service fees.

Blockchain Association and the Crypto Council for Innovation said they filed the complaint on Aug. 21 in the Circuit Court of the Seventh Judicial Circuit in Sangamon County. The filing came one month after The Digital Chamber announced a separate Sangamon County challenge.

The new complaint names Illinois Department of Revenue Director David Harris, Attorney General Kwame Raoul and Sangamon County State’s Attorney John Milhiser in their official capacities. The plaintiffs seek a declaration that the Digital Asset Tax Act is invalid, plus preliminary and permanent injunctions blocking implementation and enforcement.

Their seven counts allege preemption under the federal Internet Tax Freedom Act, violations of the Commerce Clause and federal and state due process protections, and breaches of Illinois constitutional rules on tax uniformity, delegation and the legislative process. Those are allegations, not judicial findings.

The two complaints have different captions and defendant lineups. Neither group’s public materials report a joint schedule or court order coordinating, joining or consolidating them. The version of the Blockchain Association and CCI complaint posted by the plaintiffs also leaves its case-number field blank.
