Marketplace

A number the Marketplace provides when you qualify for a health insurance exemption. When you fill out an exemption application, the Marketplace will review it and determine if you qualify. The Marketplace will mail you a notice of the exemption eligibility result. If you qualify for an exemption, the notice will include your unique identifier, called the exemption certificate number (ECN). Each member of your household who qualifies for the exemption will get their own ECN. You’ll need your ECN when you file your federal taxes for the year you don’t have coverage.

A measure of income issued every year by the Department of Health and Human Services (HHS). Federal poverty levels are used to determine your eligibility for certain programs and benefits, including savings on Marketplace health insurance, and Medicaid and CHIP coverage.

The figure used to determine eligibility for premium tax credits and other savings for Marketplace health insurance plans and for Medicaid and the Children's Health Insurance Program (CHIP). MAGI is adjusted gross income (AGI) plus these, if any: untaxed foreign income, non-taxable Social Security benefits, and tax-exempt interest.

A time when you can sign up for health insurance. You can enroll in Marketplace health coverage through August 15 due to the coronavirus disease 2019 (COVID-19) emergency.

You need to know your second lowest cost Silver plan (SLCSP) premium to figure out your final premium tax credit. In most cases, you’ll find your SLCSP premium on Form 1095-A.
