Benefits received from Social Security are disclosed on Form SSA-1099 (or RRB-1099 for railroad retirement). These forms merely report the amount received, and not the taxable amounts, which must be computed based on other income disclosed on the taxpayer’s return. Social Security benefits must be reported on either Form 1040 or 1040A. If none of the benefits are taxable, then none of them should be reported on the return.
