Wanda and Dan are both retired and will file a joint return. Wanda received Form SSA-1099 with $4,300 in box 5. Dan retired from the railroad and his Form RRB-1099 shows $6,800 in box 5. Wanda and Dan will use the combined benefits of $11,100 and only one worksheet to determine if any of their benefits are taxable.

If the taxpayer is itemizing deductions, include Medicare premiums (Part B and D) from Forms SSA-1099 and RRB-1099 so that it flows to Schedule A. Be sure to enter any federal income tax withholding. The tax software will perform all the calculations to determine the taxable amount based on other information on the return. Enter all income, including tax-exempt interest, so the software will correctly calculate the taxability of benefits. Review the Volunteer Resource Guide (Tab 2) Railroad Retirement, Civil Service, and Social Security Benefits for software entries.
