Contributions to 401(k) Plan Are Subject to Railroad Retirement Taxes
(Posted April 17, 2008)
Question 662: Are Railroad Retirement Tier 1 and Tier 2 payroll taxes taken out of my 401(k) payroll contributions?
Answer: The tax treatment of 401(k) contributions under the Railroad Retirement Tax Act is different than it is for federal income tax purposes. Contributions to a 401(k) retirement plan are considered to be creditible compenstion under the Railroad Retirement Act and hence they are subject to Tier 1 & Tier 2 taxes.
The Railroad Retirement Tax Act is administered by the Internal Revenue Service and not by the Railroad Retirement Board.
