The questions plan sponsors ask most often, answered straight.
What does a 3(21) investment co-fiduciary do?
A 3(21) investment co-fiduciary provides investment advice and recommendations to the plan sponsor, helping select and monitor the investment lineup and maintaining a documented fiduciary process, while the sponsor retains discretion over final investment decisions. This shared fiduciary structure keeps decision authority with the sponsor, supported by professional guidance and documentation the plan committee can show in a DOL audit.
When does a 401(k) plan require an annual audit?
Plans with 100 or more participants with account balances at the start of the plan year are generally required to file Form 5500 with an audited financial statement. The participant-count rule changed for plan years beginning in 2023: only participants with balances count, which moved some plans out of audit status. The TPA confirms the count each year.
What does ERISA § 408(b)(2) require of plan sponsors?
ERISA § 408(b)(2) requires plan service providers to disclose, in writing, the services they provide and the direct and indirect compensation they receive. Plan sponsors then have a fiduciary duty to determine whether the fees are reasonable for the services rendered. Reasonableness is documented through benchmarking, not assumed.
What is a Qualified Default Investment Alternative (QDIA)?
A QDIA is the investment where participant contributions default if the participant has not made an election. Under DOL regulation 2550.404c-5, plan sponsors who select a QDIA meeting the regulation's requirements (typically a target-date fund, a balanced fund, or a managed account) gain fiduciary protection for those defaulted balances.
Is a safe harbor 401(k) plan worth the employer contribution?
A safe harbor 401(k) under IRC § 401(k)(12) or (13) bypasses ADP and ACP nondiscrimination tests in exchange for either a matching or non-elective employer contribution that vests immediately, with limited exceptions. Safe harbor often makes sense when owners or highly compensated employees want to defer the full IRC § 402(g) limit and the plan would otherwise fail testing. The math depends on payroll structure.
How much does 401(k) advisory cost?
Fees vary by plan size and scope of services. Common structures include a flat annual fee, a per-participant fee, or basis-point fees on plan assets. Engagement terms are documented in a written services agreement and disclosed under ERISA § 408(b)(2).
What is Form 5500 and when is it due?
Form 5500 is the annual return jointly required by the DOL, IRS, and PBGC for most ERISA-covered retirement plans. Under current law it is generally due seven months after the plan year ends (July 31 for calendar-year plans), with a two-and-a-half-month extension available via Form 5558. Small plans (under 100 participants with balances) may file the simplified Form 5500-SF.
How does SECURE 2.0 affect small business 401(k) plans?
SECURE 2.0, enacted December 2022, expanded retirement plan rules across multiple provisions phasing in through 2027. Items affecting small employers include automatic enrollment requirements for new plans (§ 101), expanded startup tax credits (§ 102), Roth catch-up treatment for high earners (§ 603), and the student loan match provision (§ 110). Under current law, applicability depends on plan adoption date and employer size.
