The individual shared responsibility provision requires you and each member of your family to have basic health insurance coverage (also known as minimum essential coverage), qualify for an exemption from the responsibility to have minimum essential coverage, or make an individual shared responsibility payment when you file your federal income tax return.

Minimum Essential Coverage
If you and your family need to acquire minimum essential coverage, you may have several options. They include:
•Health insurance coverage provided by your employer,
•Health insurance purchased through the Health Insurance Marketplace in the area where you live, where you may qualify for financial assistance,
•Coverage provided under a government-sponsored program for which you are eligible (including Medicare, Medicaid, and health care programs for veterans),
•Health insurance purchased directly from an insurance company, and
•Other health insurance coverage that is recognized by the Department of Health & Human Services as minimum essential coverage.
U.S. citizens who are residents of a foreign country for an entire year, and residents of U.S. territories, are deemed to have minimum essential coverage.
Form 8965 provides a more detailed list Types of "Minimum Essential Coverage".

For purposes of the individual shared responsibility payment, you are considered to have minimum essential coverage for the entire month as long as you have minimum essential coverage for at least one day during that month. For example, if you start a new job on June 26 and are covered under your employer’s health coverage starting on that day, you’re treated as having coverage for the entire month of June. Similarly, if you’re eligible for an exemption for any one day of a month, you’re treated as exempt for the entire month.
