Which income components are included when calculating MAGI?

• A. Adjusted Gross Income plus any non-taxable Social Security benefits and any tax-exempt interest, with other MAGI adjustments as defined by rules
• B. Adjusted Gross Income plus only taxable Social Security benefits
• C. Wages and salaries only
• D. Taxable income after deductions

Answer: (A)

The concept being tested is how MAGI is calculated. MAGI starts with Adjusted Gross Income and then adds back items that aren’t counted in AGI but are treated as part of MAGI: non-taxable Social Security benefits and tax-exempt interest, plus any other MAGI adjustments defined by law. That’s why the correct approach is AGI plus non-taxable Social Security benefits and tax-exempt interest, with other MAGI adjustments as defined by rules. This captures income used to determine subsidies and eligibility, not just taxable income. Wages and salaries are already part of AGI, so counting only them misses the MAGI adjustments. Taxable income after deductions is not MAGI either. And taxable Social Security benefits are included in AGI if they’re taxed, so simply adding “taxable Social Security benefits” omits the non-taxable portion that MAGI adds back.
