There is no mention of adding back tax-exempt interest on Schedule 1-A, so it does not get included in modified adjusted gross income for purposes of the senior deduction.
There are many different calculations for MAGI for different things. The MAGI for Schedule 1-A is only the top 3 lines.
Thank you. I was surprised to learn there are different MAGA calculations. Why couldn't they have different names for different MAGA determinations.
It is sort of like mixed drinks. Most people know a Margarita is a drink made with tequila. But there a several variations of the drink, like a strawberry margarita, mango margarita, lime margarita, etc. They are all margaritas. It is the same with Modified Adjusted Gross Income, it comes in many different varieties!
