Some people who get Social Security have to pay taxes on their benefits. The rules are the same regardless as to whether Social Security benefits are received due to retirement or disability. If you file a federal tax return as an "individual" and your combined income is more than $25,000, you have to pay taxes. Combined income is defined as your adjusted gross income + Nontaxable interest + Â½ of your Social Security benefits. If you file a joint return, you may have to pay taxes if you and your spouse have a combined income that is more than $32,000. If you are married and file a separate return, you will probably pay taxes on your benefits. Social Security has no authority to withhold state or local taxes from your benefit. Many states and local authorities do not tax Social Security benefits. However, you should contact your state or local taxing authority for more information.
