Cryptocurrency and blockchain advocacy group The Digital Chamber has filed a lawsuit against the State of Illinois, challenging a newly enacted 0.2% tax on crypto transactions that is scheduled to take effect in 2027. On Tuesday, The Digital Chamber brought a civil suit before the circuit court of Sangamon County, naming Illinois Attorney General Kwame Raoul and Department of Revenue Director David Harris as defendants. The organization argued that the crypto tax provision, part of Illinois’ 2027 fiscal year budget, is “facially invalid.”
