CategoriesGovernment & Politics

MAGI stands for Modified adjusted gross income, a public program abbreviation also used in medicine and business.

Income measure used to determine eligibility for ACA premium tax credits, Medicaid for most adults and children, and various tax benefits. For health coverage it starts with adjusted gross income and adds back untaxed foreign income, tax-exempt interest and nontaxable Social Security benefits.

Example: Her MAGI was just under the limit, so she qualified for a premium tax credit.

Usage notes

MAGI-based rules replaced state-by-state income counting for most Medicaid groups in 2014, simplifying eligibility. The exact definition differs between programs: the MAGI used for Roth IRA contribution limits, for example, adds back different items. Asset tests generally do not apply under MAGI rules.
