Can a participant make regular 401(k) deferrals and Roth 401(k) deferrals?
Yes. However, the maximum deferral contribution amount to a plan does not change. The combination of regular deferrals and Roth 401(k) deferrals cannot exceed $15,000 for 2006. Similarly, the combination of regular age 50 catch-up deferrals and Roth 401(k) catch-up deferrals cannot exceed $5,000 for 2006. For example, if a participant who is under age 50 defers $10,000 as regular 401(k) deferrals for 2006, the participant may contribute up to $5,000 as Roth 401(k) deferrals for 2006.
