Understanding MAGI

Modified Adjusted Gross Income (MAGI) is a key figure that determines eligibility for various tax benefits and Medicare premium calculations. It starts with your AGI and adds back certain deductions.

For Medicare purposes, MAGI is simply your AGI plus tax-exempt interest income. This is the figure that determines whether you'll pay IRMAA surcharges.

Components That Influence Your MAGI

Understanding what goes into your MAGI helps you manage it effectively:

MAGI Components

  • Wages and Salaries: Employment income
  • Business Income: Self-employment and business profits
  • Capital Gains: Investment profits
  • Retirement Distributions: IRA, 401(k), pension income
  • Social Security Benefits: Taxable portion
  • Tax-Exempt Interest: Added back for Medicare MAGI
  • Rental Income: Net rental profits
