let me restate the support question.. When you look at what it costs to run the entire household (rent, food, utilities, transportation, insurance, medical bills, etc.) who pays more than 50%? you or Mom?
also, whose income is higher? you or Mom? (I assume you each make more than $4300 per year)
if Grandmother has a higher income than Daughter AND Grandmother provides more than 50% of the household support, Grandmother can claim granddaughter and file HOH while Daughter files Single.
did you run your scenario through the IRS tool? run it both for yourself then a 2nd time as if you were Grandmother
