Modified Adjusted Gross Income Calculation

dwitkow08873 — Wed, 14 Jan 2026 18:47:04 GMT

The Modified Adjusted Gross Income (MAGI) seems to be calculated differently for different purposes (eg. Net Investment Income Tax (FED form 8960), etc.)

Does Turbo Tax Provide a Standardized Table of the various Income source that needs to be included/removed from the AGI based on the various purposes of MAGI calculation; e.g. per FED Form (traditional IRA deductibility, ROTH IRA Contribution limits, additional ACA tax, etc.)

No, there isn't a standardized table provided by TurboTax. As you mentioned, the calculation of MAGI is different depending on the deduction. For example, to deduct a traditional IRA requires a MAGI calculation where the following are added to AGI (adjusted gross income):

The IRA deduction itself
Student loan interest deduction
Foreign earned income exclusion and housing deduction
Excludable savings bond interest

For a Roth IRA deduction, the MAGI includes the following add ons to the AGI:

Student loan interest
1/2 of Self employment tax paid
Deductible IRA contributions (not Roth)
Foreign earned income exclusion and housing deduction
Excluded savings bond interest

The two are similar, but have some slight differences. TurboTax will automatically calculate MAGI when it's needed for determination of a deduction or credit.

For a more in-depth treatment of MAGI please see What is Modified Gross Income and How Is It Calculated?
