Modified Adjusted Gross Income is used when computing a specific deduction or credit. Basically, it means that something is being added back to Adjusted Gross Income. MAGI is usually calcuated in the following way:

If you use Form 1040:

Take your Adjusted Gross Income on Line 36 and add back in:

If you use Form 1040A:

Take your Adjusted Gross Income from Line 21 and add back in:

  • IRA deduction.
  • Student loan interest deduction.
  • Tuition and fees deduction.
  • Exclusion of quialified savings bond interst shown on Form 8815.
  • Exclusion of employer-provided adoption benefits shown of Form 8839.

You will need to know your MAGI for almost all deductions (like IRAs) and credits (like the Child Tax Credit and Education Expense Credits). To learn more about MAGI, you should read Publication 17 from the IRS.

Each spouse can contribute an additional $1,000 if he or she is age 50 or older by the end of 2007. So tap it out if you can! Thanks for the post! […]
