Beginning in 2014, unless you are covered by an exemption, you are required to maintain basic health insurance coverage (known as minimum essential coverage) for yourself and any of your dependents, or pay a shared responsibility payment (a penalty). The requirement to maintain coverage or pay a penalty is generally called the “individual mandate.”
The penalty is the lesser of: (i) the greater of a flat dollar amount or a percentage of your household income, or (ii) the national average premium for the lowest-level plan providing minimum essential coverage. You must make the shared responsibility payment when you file your federal income tax return. Married individuals who file a joint return for a tax year are jointly liable for any shared responsibility payment.
