you've posted in a few places, but can you explain the full story here? I feed like there are pieces missing.
How much does your mother currently earn (excluding Social Security)? More or less than $4400 is the only thing that matters for this question.
Are you providing more than 50% of her support?
if less than $4400 and more than 50% of her support, she CAN BE claimed as your dependent.
Is your objective to get her medical insurance via the Marketplace? is your objective just to give her spending money in return for the chores she does around the house? (I presume you are not asking her to pay rent, so there is some quid pro quo here).
can you just explain the bigger picture? it'll be easier for this forum to answer your question(s).
