Where Is a Publication 915 Worksheet Available?

Publication 915 is available on the Internal Revenue Service's website, IRS.gov. The publication includes worksheets and information to help filers determine whether Social Security benefits reported on Form SSA-1099 and Railroad Retirement Board benefits reported on RRB-1099 are taxable.

To complete the first worksheet in Publication 915 to figure taxable benefits, a taxpayer enters the total amount of his lump-sum benefits payments, payments reflected on Forms SSA-1099 and RRB-1099, taxable pension amounts, tax-exempt interest income and excluded income, and then he follows the calculation instructions. To determine whether his benefits are taxable, a taxpayer compares his worksheet totals to the base amount for his tax status, explains the Internal Revenue Service. The agency's website offers blank and sample completed worksheets.
