There is no one single MAGI. MAGI differs depending on the tax situation.
MAGI calculation
To calculate your modified adjusted gross income, take your AGI and "add-back" certain deductions. Many of these deductions are rare, so it's possible your AGI and MAGI can be identical. Different credit and deductions can have differing add-backs for your MAGI calculation. According to the IRS, your MAGI is your AGI with the addition of the appropriate deductions, potentially including:
- Student loan interest
- One-half of self-employment tax
- Qualified tuition expenses
- Tuition and fees deduction
- Passive loss or passive income
- IRA contributions
- Non-taxable social security payments
- The exclusion for income from U.S. savings bonds
- Foreign earned income exclusion
- Foreign housing exclusion or deduction
- The exclusion under 137 for adoption expenses
- Rental losses
- Any overall loss from a publicly traded partnership
