Contribution and Escalation Mechanics: … Continued

In Summary Mandatory Roth Contributions for High Earners: Effective January 1, 2026, “High Earners” (defined as participants with prior-year FICA wages exceeding $150,000) are required to make all catch-up contributions—including the new “Super Catch-Up” for participants aged 60–63—on a Roth (after-tax) basis. Exclusions and Plan Limitations: The mandate strictly applies to employees with W-2 FICA … Continued

In Summary Common Errors and Overpayments: Due to the complexity of retirement plan rules, errors are common, resulting in excess amounts (operational failures). If these excess funds are distributed to a participant, it becomes an overpayment failure, which can stem from issues like inaccurate testing, incorrect vesting, or ineligible distributions. Correction Relief for Inadvertent Overpayments: … Continued

In Summary The 80-120 Rule for Audit Requirement: A retirement plan’s need for an annual audit is determined by counting participants with account balances on the first day of the plan year. The 80-120 rule is an exception that allows a plan with 80 to 120 participants to file as a small plan (no audit) … Continued

In Summary Risk of Tainted Assets: Directly merging plan assets preserves their source classification, creating a risk that previous qualification errors in the merged plan (resulting in “tainted assets”) could affect the audited financial statements of the successor plan. Rollovers Eliminate Risk: The optimal way to avoid tainted assets is by having participants conduct rollovers … Continued

In Summary Unclear Deadlines for 401(k) Deferrals: The Department of Labor (DOL) regulations for 401(k) deferral deposits are unclear, using “earliest” and “reasonably” rather than a firm deadline. While small plans (under 100 accounts) have a 7-day safe harbor, large plans do not. As a result, many large plans adopt a 3-day industry standard, which … Continued

In Summary Funded Plans, the Audit Requirement: The single most important factor determining if a large welfare plan needs a CPA audit is its funding status. If a plan uses a separate trust account (such as a 501(c)(9) VEBA) to hold assets or pay benefits—making it “funded”—it must undergo an audit of the entire plan … Continued

In Summary Designated Roth Accounts Contribution Rules: Participants in 401(k), 403(b), or 457(b) plans can make after-tax contributions to a designated Roth account. These contributions are combined with any pre-tax deferrals to count toward the annual limit ($23,500 in 2025).
