401(k) Plan Sponsor FAQs

Are you a fiduciary to our plan?

Yes. We serve as an ERISA 3(21) co‑fiduciary—you retain discretion; we provide prudent, documented recommendations and monitoring. If you prefer discretion delegated, we can discuss a 3(38) option via a partner.

How do you charge for 401(k) advisory?

We use a transparent, blended asset‑based schedule, with flat and hybrid options available. Most plans fall between 0.20%–0.75% annually, disclosed under 408(b)(2) and benchmarked each year. Minimums/caps may apply and are shown in your proposal.

Do you work with our current recordkeeper/TPA/payroll?

Yes. We’re provider‑agnostic and coordinate with your existing providers based on service quality, technology, payroll fit, fiduciary support, investment options, and total plan cost.

What employee education do you provide?

Workshops, office hours, and targeted communications aligned to plan milestones. We track participation, deferrals, and engagement and review results with your committee.

Do you help with employer‑sponsored 529 plans?

  • Yes. We include a concise 529 education module alongside our 401(k) communications to help HR enable payroll contributions and educate employees.
  • Employer benefits: Stronger total‑rewards story, low‑lift implementation (payroll + education), supports recruiting/retention.
  • Employee benefits: Tax‑advantaged growth, potential state tax deductions/credits (state‑specific), easy payroll contributions.
  • If funds aren’t used for college: Under current law, certain unused 529 balances may roll into the beneficiary’s Roth IRA within limits (e.g., 15‑year account age, annual IRA limits apply, lifetime cap currently $35,000).
  • Scope: Education‑focused; individualized advice requires a separate engagement.
