An Ssdi Taxable Income Calculator will determine the amount of your disability benefits that can be taxed depending on your tax filing status and overall income. The calculator requires the following information: adjusted gross income, tax-exempted interest, filing status and the total amount of the SSDI benefits obtained. It then sums up both your incomes and matches with IRS limits. Your income will make you either have 0 percent of your benefits taxable, half or 85 percent of your benefits taxable. Although the calculators would give nice estimates, it is important to have the help of a tax professional who would make sure that the information is accurate as well as you have multiple sources of income.
