Question: What’s added back into my AGI at the end of the year? For example is my rental income, retirement account withdrawals, etc. included in MAGI.

Answer: I have received many questions like this and have answered few, mostly because I wasn’t sure of the answer myself. The problem is official web sites such as the Healthcare.gov site or IRS.gov tend to focus only on earned income and do not provide much guidance as to how to handle other forms of income or various tax deductions when it comes to calculating MAGI (modified adjusted gross income) for purposes of determining subsidy eligibility under the ACA. I can now refer you to an authoritative source. We just published an article by guest author, A. Marshall, in our News and Commentary section, titled MAGI - What It Is and What It Isn’t.
