The individual responsibility requirement, also known as the individual mandate, is a provision of the Affordable Care Act requiring that all citizens obtain a minimum standard of health insurance coverage.
As of January 1, 2019, there is still a requirement to maintain coverage, although you will not be charged a tax penalty unless you live in California, District of Columbia, Massachusetts, New Jersey, or Rhode Island. Still, maintaining “Minimum Essential Coverage” is required by federal law, and obtaining such coverage determines your eligibility for premium tax credits and most special enrollment periods. Also, health insurance coverage provides important financial protection in case you need health services such as when you are sick or have an injury. IRS, Individual Shared Responsibility Provision.
