My parents have no income except Social Security and are both over 65. I purchased a home for them to live in (in 2019) and they live there rent free, I do not reside there. This furnishes over 50% of their living costs by a significant margin; in short I looked at the IRS site and believe they qualify as eligible dependents. They only file to receive a small return. However, they are both on Medicaid, receive SNAP benefits, and my father receives additional Hospice services as well. I do not want to claim them if it will effect any of those programs. Will claiming them have any effect?
