The individual shared responsibility provision,[1] less formally known as the individual mandate, was the health insurance mandate imposed on individuals by the Affordable Care Act in the United States until tax year 2019. This individual mandate required most individuals and their families to have a certain minimal amount of health insurance, with certain exemptions. Otherwise, they were required to pay the individual shared responsibility payment as a fine.[2][3] It was one of the many Affordable Care Act tax provisions. The federal tax penalty for violating the mandate was eliminated by the Tax Cuts and Jobs Act of 2017, starting in 2019.[4] (In order to pass the Senate under reconciliation rules with only 50 votes, the requirement itself is still in effect, just with the fine set to $0).[5][6][7][8]
