Modified Adjusted Gross Income Calculation

[dwitkow08873]

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.
