Modified Adjusted Gross Income

This is your gross income (wages, dividends, rents, and so forth) less adjustments from gross income (business deductions, rental expenses, alimony, moving expenses after 1993, and so forth) plus certain modifications. The modifications depend on the particular use of the modified adjusted gross income. For example, a modified version of adjusted gross income is used to calculate the taxable portion of your Social Security benefits. See Adjusted Gross Income.
