Understanding Modified Adjusted Gross Income (MAGI) is crucial for taxpayers as it determines eligibility for various tax credits and deductions. Often confused with Adjusted Gross Income (AGI), MAGI provides a more inclusive view of an individual’s income by factoring in specific adjustments.
Locating MAGI Figures on Tax Forms
Finding your Modified Adjusted Gross Income (MAGI) on tax forms can be complicated. Unlike AGI, which is clearly listed on IRS Form 1040, MAGI must be calculated by adjusting your AGI. These adjustments are necessary to determine eligibility for tax benefits like the Premium Tax Credit or Roth IRA contributions.
To calculate MAGI, begin with the AGI on line 11 of Form 1040. 1Internal Revenue Service. Adjusted Gross Income Add back specific deductions and exclusions as required for the provision you’re testing. For Premium Tax Credit MAGI, add amounts such as tax‑exempt interest reported on line 2a of Form 1040 and foreign earned income and housing amounts from Form 2555. 2Internal Revenue Service.

Foreign earned income exclusions, reported on Form 2555, also adjust AGI to MAGI for several provisions, including the Premium Tax Credit and Roth IRA eligibility. This ensures eligibility for tax-related programs is based on a comprehensive assessment of income.
Differences Between AGI and MAGI
Adjusted Gross Income (AGI) reflects total income minus allowable deductions, such as educator expenses and student loan interest. It is used to calculate tax liability and eligibility for deductions.
MAGI builds on AGI by including additional income sources and deductions excluded from AGI. This broader calculation determines eligibility for tax benefits like the Premium Tax Credit or Roth IRA contributions. For example, Premium Tax Credit MAGI adds back tax‑exempt interest and certain foreign income amounts, while Roth IRA MAGI adds back items such as the student loan interest deduction and the traditional IRA deduction.
To calculate MAGI, certain items must be added back to AGI depending on the rule you’re applying. For Roth IRA purposes, add backs include the student loan interest deduction and foreign income exclusions. 3Internal Revenue Service.

Adjustments That Influence MAGI
Calculating Modified Adjusted Gross Income (MAGI) involves adjustments to AGI that impact eligibility for tax benefits. Understanding these adjustments is essential for accurate tax planning.
Tax-Exempt Interest
Tax-exempt interest, such as income from municipal bonds, is excluded from federal income tax but must be added back when calculating MAGI for the Premium Tax Credit. For example, if a taxpayer earns $5,000 in tax-exempt interest, this amount is added to their AGI to determine PTC MAGI. Including tax-exempt interest in PTC MAGI ensures eligibility for programs like the Premium Tax Credit is based on total financial resources.
Certain Foreign Income Exclusions
Foreign income exclusions, such as those under IRC Section 911, allow taxpayers to exclude a portion of foreign earned income from U.S. taxation. However, this excluded income is added back to AGI when calculating MAGI for provisions like the Premium Tax Credit and Roth IRA eligibility.
Student Loan Interest
The student loan interest deduction, capped at $2,500 annually, reduces AGI but is added back when determining Roth IRA MAGI. 4Internal Revenue Service. Topic No. 456, Student Loan Interest Deduction For instance, if a taxpayer deducts $1,500 in student loan interest, this amount is included in the Roth IRA MAGI calculation. This adjustment is particularly significant for those contributing to a Roth IRA, as MAGI determines contribution limits.
Qualified Retirement Contributions
Contributions to traditional IRAs can reduce AGI, but the traditional IRA deduction is added back when calculating Roth IRA MAGI. For example, if a taxpayer claims a $6,000 traditional IRA deduction, that amount is included when computing Roth IRA MAGI to assess Roth contribution eligibility. 5Internal Revenue Service.
