Note that MAGI is based upon AGI which is found on line 37 of form 1040 and includes line 13 in the total.
That's my thinking - that it's basically line 37 with a couple of other possible adjustments, the most common being tax exempt interest (see link below). So this would net out cap gains minus losses and another $3,000 against ordinary income (assuming there's additional available).
So then to to my understanding this means that for those with carryover losses they can produce income to the extent of those losses (less $3,000 that will go toward ordinary income) without impacting the MAGI under the ACA. Correct?
