Illinois’ new Digital Asset Tax may face delays as legal challenges are already making their way through the courts. On July 21, 2026, The Digital Chamber filed a lawsuit in the Circuit Court of Sangamon County, Illinois, challenging the Act on both federal and state constitutional grounds. According to the complaint, the organization argues that the tax violates the U.S. Constitution’s Commerce Clause and Due Process Clause. The lawsuit also alleges violations of the Illinois Constitution’s Uniformity Clause, Due Process Clause, and Proportionate Penalties Clause. Additionally, the complaint contends that the Act discriminates against internet-based electronic commerce in a manner prohibited by the Internet Tax Freedom Act.
The litigation introduces uncertainty regarding the timing and ultimate viability of the Digital Asset Tax. While the law remains on the books unless changed by the courts or legislature, businesses impacted by the measure should closely monitor developments as the case moves forward. For tax professionals, the challenge highlights the continuing tension between states seeking to expand taxation of emerging digital activities and constitutional limitations on those efforts. This is an area where judicial outcomes could have implications beyond Illinois, particularly as other states evaluate similar approaches to taxing digital economy transactions.
The litigation is in its early stages, and future court decisions could affect the administration, enforcement, or implementation of the tax. The Sales Tax Institute will continue to monitor this case and provide updates (The Digital Chamber v. State of Illinois, Complaint filed July 21, 2026, in the Circuit Court of Sangamon County, Illinois.).
