The U.S. Chamber of Commerce filed a Nov. 9 amicus brief challenging Illinois’ digital-asset tax, according to the group’s case page, adding its legal arguments to two pending cases.
The U.S. Chamber argues that the tax conflicts with the federal Internet Tax Freedom Act and the Constitution’s dormant Commerce Clause. Those arguments are before the Sangamon County Circuit Court in two pending cases.
The Illinois statute sets a 0.2% tax on the value of digital assets involved in covered exchanges, transfers and storage for customers in the state. Brokers must collect the tax from customers, and the proceeds go to Illinois’ General Revenue Fund.
Under the agreement, the law’s effect and enforcement are stayed until July 1, 2027. The plaintiffs requested a decision by March 1, 2027, in a joint motion. Illinois does not oppose the requested date, but the schedule still requires court approval.
The court cases are separate from a dispute over the tax’s proposed rules. Several groups told Illinois the proposed broker standard could apply to decentralized exchanges that earn fees, a concern covered in EconoTimes’ report on their request for rule changes.
