Private Railroad Pensions May Reduce RRB Supplemental Annuities

Railroad retirement annuitants are reminded that receipt of a private railroad pension may reduce the 

amount of a supplemental annuity payable by the Railroad Retirement Board (RRB). The following 

questions and answers provide information on this subject and how 401(k) plans are affected by the 

Railroad Retirement Act (RRA).

1. What are the eligibility requirements for a supplemental annuity?

Monthly supplemental annuities are payable to employee annuitants with 25 or more years of

railroad service who have at least one month of creditable railroad service before October 1981, and a 

“current connection” with the railroad industry. Annuitants with 30 years or more of railroad service 

may begin receiving a supplemental annuity at age 60, whereas annuitants with 25-29 years of service 

may do so at age 65. (Disabled annuitants under full retirement age, which is age 67 for persons born in 

1960 or later, must relinquish employment rights for a supplemental annuity to be paid by the RRB.) 

Monthly supplemental annuity rates vary based on an annuitant’s years of railroad service. The 

maximum monthly supplemental annuity rate is $43.

2. How is a “current connection” determination made under the RRA?

A current connection determination is made when an employee files for a railroad retirement

annuity. If an employee worked for a railroad in at least 12 months in the 30 months immediately 

preceding the beginning date of his or her railroad retirement annuity, the employee has a current 

connection. 

Employees who do not meet this requirement, but who have at least 12 months of railroad service 

in an earlier 30-month period, may still qualify for a current connection. This alternative generally 

applies if an employee did not have any regular employment outside the railroad industry after the end 

of that last 30-month period that included 12 months of railroad service, and before the month his or her 

annuity begins. 

A current connection can also be "deemed" for purposes of a supplemental annuity if the employee 

completed 25 years of railroad service, was involuntarily terminated without fault from his or her last 

job in the railroad industry, and did not thereafter decline an offer of employment in the same class or 

craft in the railroad industry regardless of the distance to the new position.

3. How does the receipt of a private railroad pension affect payment of a supplemental

annuity?

If a retired employee also receives a private pension funded entirely, or in part, by a railroad 

employer, the supplemental annuity is permanently reduced by the amount of the monthly private 

pension that is based on the railroad employer’s contributions. However, if the employer reduces the 

pension for the employee’s entitlement to a supplemental annuity, the reduction amount is restored to 

the supplemental annuity (but does not raise it over the $43 maximum). There is no reduction for a 

pension paid by a railroad labor organization. 

4. What if an employee elects to receive a private railroad pension in a lump-sum payment

instead of as a monthly benefit?

If a retired employee elects to receive his or her pension in a lump-sum payment instead of as a 

monthly benefit, the supplemental annuity is reduced in the same way as it would be if the employee 

was receiving the monthly benefit. If the lump sum is paid in installments, the installment payments are 

not considered monthly benefit payments, but part of the single lump-sum payment. 

5. Does the receipt of a 401(k) plan distribution reduce the amount of a supplemental

annuity?

No. In a legal opinion issued in January 2014, the RRB’s General Counsel determined that 401(k) 

plans should not be considered supplemental pension plans as defined by the RRA and, therefore, 

employee supplemental annuities should not be reduced due to the receipt of 401(k) distributions. 

6. Are employee contributions to a 401(k) plan subject to railroad retirement tier I and

tier II payroll taxes? 

Yes. The treatment of 401(k) plans under railroad retirement law conforms with the treatment of 

such plans under social security law. Consequently, employee contributions to 401(k) plans are subject 

to railroad retirement payroll taxes and are treated as creditable compensation for railroad retirement

benefit purposes. (For example, an employee earning $40,000 a year, but who has 10 percent of his 

earnings deferred under a 401(k) plan, would have only $36,000 reported to the Internal Revenue Service

as earnings subject to Federal income tax. However, the entire $40,000 would be subject to railroad 

retirement payroll taxes and therefore creditable as compensation under the RRA.) 

7. How can a person get more information about how private railroad pensions and 401(k)

plan payments affect supplemental annuities?

More information is available by visiting the RRB’s website, RRB.gov, or by calling an RRB office

toll-free at 1-877-772-5772. Persons can find the address of the RRB office serving their area by 

clicking on the Field Office Locator tab at RRB.gov or by calling the agency’s toll-free number. RRB 

field offices currently offer limited in-person service by appointment. To schedule an appointment, 

call 1-877-772-5772. Individuals should bring a photo ID when visiting a field office, and, depending on 

guidance from the Centers for Disease Control and Prevention for the county in which the field office is

located, may be required to wear an appropriate face mask. In such circumstances, if visitors do not have 

a mask, one will be provided for them.
