Yes. This began in 2014. If you are a U.S. citizen or lawfully present resident, you are required to buy health care coverage for yourself and your dependents. There are just a few exceptions to this requirement such as members of certain religious sects,prisoners, undocumented immigrants, and Indian tribal members. Depending on your income and household status, you may qualify for a subsidy that can lower your insurance costs. If you decide not to get health insurance, you may be subject to a tax penalty.
