Which of the following is NOT affected by MAGI calculations?

The concept of Modified Adjusted Gross Income (MAGI) is utilized in various financial contexts, particularly with respect to determining eligibility for certain tax benefits and health insurance subsidies. In the context of this question, MAGI typically includes a variety of income sources, but some specific types of income are excluded from its calculation.

Foreign earned income is specifically excluded from MAGI calculations when it qualifies for the foreign earned income exclusion under IRS rules. Since foreign earned income can be excluded from gross income for tax purposes, it does not contribute to the calculation of MAGI, which is important when determining eligibility for programs like the Premium Tax Credit or Medicaid.

In contrast, taxable income, tax-exempt interest, and Social Security benefits can all play a role in the calculation of MAGI. Taxable income typically includes earned income and certain investment income, while tax-exempt interest is counted but only to some extent depending on its nature. Social Security benefits may also need to be considered, as they can impact overall income levels. Therefore, foreign earned income stands out as the type of income that does not influence MAGI calculations.
