4. Your taxable benefits and modified adjusted gross income are figured on a worksheet in the Form 1040A or Form 1040 Instruction booklet.
5. You can do the following quick computation to determine whether some of your benefits may be taxable:
- First, add one-half of the total Social Security benefits you received to all your other income, including any tax exempt interest and other exclusions from income.
