Under the Affordable Care Act, eligibility for income-based Medicaid 1 and subsidized health insurance through the Marketplaces is calculated using a household’s Modified Adjusted Gross Income (MAGI). The Affordable Care Act definition of MAGI under the Internal Revenue Code 2 and federal Medicaid regulations 3 is shown below. For most individuals who apply for health coverage under the Affordable Care Act, MAGI is equal to Adjusted Gross Income. This document summarizes relevant federal regulations; it is not personalized tax or legal advice. Consult the Health Insurance Marketplace for your state, your local Medicaid agency, or a legal or tax advisor for assistance in determining your MAGI.
