Adjusted gross income (AGI) is pretax income minus certain deductions or “adjustments” as specified by the IRS in order to determine your tax liabilities. However, certain tax deductions and tax credits require you to add back or “modify” some of those adjustments to determine your qualification threshold. Modified adjusted gross income, or MAGI, is AGI plus appropriate “add-back” deductions.

In most instances, AGI and MAGI are similar or even identical. Common MAGI add-backs include non-taxable Social Security benefits, student loan interest, tuition expenses and tuition and fees deductions, passive income or losses, and foreign-earned income.
