There are no refunds for any pre-1951 taxes paid.
If an employee has completed 120 months of service at the time of retirement but is
not qualified for a dual benefit windfall, he/she is eligible for a refund of certain
tax contributions at the time he/she begins receiving an annuity. Eligible RR employees
will receive the refund without application.
If an employee has both RR and SS earnings after 1974, and the total exceeds the maximum
creditable amount under the RR Act, the excess tax contribution may be claimed on
the Federal income tax return.
