So here is whats happening, My mother who is a new resident in the United States since 2016, I got her insurance through the marketplace , She has been having coverage since then , However, She doesn't work and she make zero income so because of that she hasn't been filing any taxes since then , However , now We were asked by healthcare.gov for proof of her tax return and when I explain them the situation, They told me I have 2 option to add her as my dependent which i rode somewhere dependents are not eligible for premium tax credit or file the late tax return now for 2016 , How is this possible , Can i file tax for her for 2016 when she has no income , Can i put like $1000 income for her for the late tax return just to have her premium tax credit going ? any idea ... and she is not eligible for Medicaid as well.
