On June 1, 2023, in United States v. Liberty Global, Inc., the US District Court for the District of Colorado held that the US Department of Justice (DOJ) can assert and seek judgment for federal income tax deficiencies using a common law right of action, bypassing the usual statutory tax deficiency procedures outlined in the Internal Revenue Code (IRC). This decision might encourage the DOJ to seek tax collections through court judgments moving forward without following the IRC’s deficiency procedures.
