Ok, I give up on the pension/disability/health insurance angle because
I do not understand that health insurance and who is requiring you use a particular policy. That is ok! I don’t need to understand it.
If you can get your MAGI down (not AGI) Then yes, that’s probably the way to go. I’m sure your accountAnt son knows that the ACA looks at MAGI. I honestly never figured out what all goes into MAGI even though I look at it on my income tax statement, but when we used the ACA our income was so low anyway I never worried about it. It was $30,000 for 2 people.
