After you file

MAGI is used for more that IRAs. In my case, I want the information for for preventing Medicare excise tax. I want to do conversions from my IRA to Roth to keep our RMD value down. Right now it isn't critical because of the joint filing values. But when one of us dies that benefit goes away. It seems like no money planner takes that into consideration. TT has all the information now so why not show it. If there is more than one MAGI then show them.
