For years, employers have been offering traditional and Roth 401(k) plans, but the latter has not been very popular–until now. Looking for someone under 40 who has chosen to participate in a company Roth 401(k). I’d like to find out why you chose a Roth over traditional 401(k) Requirements: Please no PR types or folks selling me their book. I’m looking for a participant under age 40 who has chosen a Roth 401(k) to save for retirement. If you are a PR person who can get me an employee who uses a Roth, that would be great.
