Time Limitations Under the RRA
Section 9 of the Railroad Retirement Act (RRA) provides that the RRB's records of service and compensation are conclusive as to the amount of compensation paid during the period covered by the report, unless an error is called to the RRB's attention within four years of the day on which the report was required to be made. Employers are required to file with the RRB, on or before the last day of February, an annual report of service and compensation for employees who performed compensated service in the preceding calendar year.
