A portion of your disability benefits may be taxable if you have income other than your Social Security benefits. If your income, when combined with your disability income, totals between $25,000 and $34,000 if you are single or between $32,000 and $44,000 if you are married, 50 percent of your benefits are taxable.
If your combined income exceeds these levels, 85 percent of your benefits can be taxed.
