Some of your Social Security benefits may be taxed depending on your other income and filing status. Social Security only becomes taxable when half of your benefits are added to other gross income and that total exceeds an amount determined by your filing status. For example, the amount for married filing jointly is $32,000, and for single taxpayers it is $25,000. Use the Social Security work sheet in your tax booklet to calculate the taxable amount, if any. Or use the IRS Interactive Tax Assistant.
