This is a question my mom and I were discussing last night...I have no idea and she is going to call her accountant....But my grandmother who lives with my mom is 87 years old. She gets a very small Social Security Check each month in the amount of about $800 dollars. Out of this check comes all of my grandmother's life insurance etc and leaves her with about $200 per month. My mom feeds her, pays the bills etc.....could my mother claim her as a dependent?? If she did would it have the chance to lessen my grandmother's Social Security Check?? Just wondering if anyone knows.
