I have seen that declaring a parent as a dependent will not affect Medicare or Social Security benefits, but cannot find information on any potential impact to Medicaid. My mother would completely qualify as my dependent in terms of the IRS, but we both worry that she would lose Medicaid. I make a decent salary, but not enough to easily support both of us and could really use the tax break.
Also, would living with me affect the benefit? Will they take my income into account next time they review her case if she moves in with me? She is confused and intimidated by their questions each year, and doesn't know what to tell them if she moves in with me.
