The U.S Supreme Court has ruled that the Internal Revenue Service was authorized to issue regulations extending health insurance subsidies to coverage purchased through health insurance exchanges run by the federal government or a state. King v. Burwell, No. 14-114 (June 25, 2015). This means employers cannot avoid employer shared responsibility penalties under Internal Revenue Code section 4980H (“Code § 4980H”) with respect to an employee, solely because the employee obtained subsidized exchange coverage in a state that has a health insurance exchange set up by the federal government instead of by the state. It also means that President Barack Obama’s 2010 healthcare reform law will not be unraveled by the Supreme Court’s decision in this case. The law’s requirements applicable to employers and group health plans continue to apply without change.
