Take the amount on Line 11 of the 1040 and then add any of the credits listed below. The result is the MAGI.
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
