It depend's on the type of disability income you get. If you are getting S.S.I., you do not file taxes on it. If you get S.S. sometime's it is taxed, but not likely. Call H & R Block, and they will give you free advice. Just tell them your type of income, and they will tell you right then if you file or not. You can file for a state refund in most state's if one or more household member's get S.S.I disability and if you rented your home or property. It is called a renter's tax rebate. It's easy to fill out, and you can download the form on line.
Well it depends on the type of income you have. If you are on permanent disability and receiving income from SS then no, you don't have to file but if you are disabled and can still work a little and earn income then yes you should have to file if you earn more than 400.00 dollars in a year. You can always check with a tax preparer and they should be able to tell you.
