Benefits Paid by the Railroad Retirement Board.
Enter any federally taxed retirement benefits paid by the Railroad Retirement Board (RRB), such as Tier I and Tier II benefits, railroad retirement sick pay, disability, and unemployment benefits, included in federal AGI. List the name of the benefit paid on line 14a and the related amount on line 14b. Filers must attach a copy of Forms RRB‑1099, RRB‑1099-R, 1099-G, and W-2 from U.S. Railroad Retirement Board Sickness and Unemployment Benefits Section. Paper filers must attach a copy of pages 1 and 2 of Federal Form 1040 or 1040-SR to your Nebraska return.
You must do a computation to determine the Tier I amount if you received both Form SSA-1099 for social security benefits AND Form RRB-1099 for Railroad Retirement Board Tier I payments because the Social Security Benefits Worksheet in the federal tax booklet adds the benefits together to calculate the taxable benefits entered on line 6b of the Federal Form 1040 or 1040-SR.
Use the total amount of Tier I benefits divided by the total benefit amount reported on line 6a of the Federal Form 1040 or 1040-SR to calculate a ratio to six decimal places, then round to five decimals. For example, .454467,would be rounded to .45447 (45.447%). Multiply this ratio by the amount on line 6b of the Federal Form 1040 or 1040-SR. Enter the result for the Tier I amount on the Nebraska Schedule I.
