I’m married filing separate, however, I have been getting financial support from my parents since I am not legally separated. Can they amend their taxes to claim me?
I didn’t earn any income from a job or my business, because I am the sole caretaker for my small child. Do I need to file my taxes with no income to report? I didn’t file for an extension, is it still possible? How can I get a Schedule C if I didn’t file because there was no income to report?
If you had no taxable income you have no reason to file a tax return, nor would it help you to do so. You do not have to file unless you have a 1095A for having marketplace health insurance. If you did not work and earn any income, either W-2 income or self-employment income, then you are not eligible to receive refundable child-related credits like child tax credit or earned income credit. If you had no self-employment income, you have no reason to file a Schedule C -- what would you enter on it? What business expenses can you claim?
If you were supported by your parents then they might be able to claim you ---and perhaps your child-- as dependents on their tax return. They could get the $500 credit for other dependents by claiming you as a qualified relative, and perhaps claim their grandchild as a qualifying child.
