Latest responses to “Adjusted Gross Income and Modified Adjusted Gross Income” Copyright 2013, MoneyBlueBook.com 399530 2009-09-08T16:23:24-07:00 Helen Hello, MAGI is now being use to determine how much medicare you will pay- not only that SSI is using 2007 for application in 2009-which I have retired and not drawing SS. The Government just "slipped it in" The stimulus was figured using MAGI. Your site is very informative- Thank You 399520 2009-06-08T16:46:42-07:00 Joe This article is wrong. I was informed by a very reliable (and extremely attractive) tax professional that employee contributions to 401K are in fact added to the MAGI. 399500 2008-04-02T16:25:45-07:00 Raymond Hey Ken, Yeah these are terms that are frequently used but often overlooked. The "modified" part seems to slip people's minds due to the frequent similarity of the AGI and MAGI. 399510 2008-04-02T15:34:26-07:00 Ken Clark, CFP Classic... I did just a piece on this as well because I get asked about it so much! Great write up! -Ken
