The US Justice Department and business groups filed statements backing legal challenges to Illinois’ 0.2% digital asset tax on November 6, 2026; a decentralized finance coalition filed a brief on November 11, 2026. The tax applies to the value of digital assets exchanged, transferred or stored even when a transaction makes no profit. Its start was delayed from January 1 to July 1, 2027, while the challenges proceed.
The business groups argued that the tax could bring compliance costs and might violate federal and constitutional protections. The Justice Department said it could conflict with federal crypto policy. The DeFi coalition warned that proposed rules could place tax-collection duties on developers and others who lack customer information or control over user funds.
