Why this matters to trucking businesses

If you sponsor a 401(k), SIMPLE IRA, or other benefit plan for drivers and back-office staff, seemingly routine admin missteps can draw the attention of the U.S. Department of Labor (DOL) or the IRS. A new KLR advisory (published March 2, 2026) spotlights the top triggers that often escalate from “paperwork problems” into costly investigations. Understanding them—and tightening your controls—can keep your fleet focused on freight, not fines.

The six red flags regulators look for

Excessive or incorrect service-provider fees. Plans must pay only “reasonable” fees for services actually rendered. Poorly documented fee reviews can be read as weak fiduciary oversight.
Late deposits of employee deferrals. For most plans, DOL requires that employee contributions be deposited as soon as they can be separated from company assets; small plans (generally under 100 participants) get a seven-business-day safe harbor. Chronic delays are a common enforcement trigger.
Late or incomplete Form 5500 filings. Missed or inaccurate annual returns invite penalties and deeper reviews. Relief may be available if you proactively correct through the DOL’s Delinquent Filer Voluntary Compliance Program (DFVCP)—and the IRS generally coordinates penalty relief when DFVCP is satisfied.
Participant complaints. A single complaint about fees, benefit calculations, or communication lapses can open the door to a broader inquiry.
Use of alternative or hard‑to‑value investments. Private equity, real estate partnerships, and similar assets demand robust valuation and fiduciary documentation; gaps here draw scrutiny.
Prohibited transactions. ERISA bars certain dealings with “parties in interest” (for example, loans to related entities or misuse of plan assets). These issues almost always get immediate attention.

What this looks like in a fleet environment

Owner-operators who’ve grown into small fleets often run “small plans” with fewer than 100 eligible employees—meaning the seven-business-day safe harbor can apply to 401(k) or SIMPLE IRA deferral deposits. But regulators still expect deposits as quickly as your payroll process allows. If your best historical turnaround is three days, a week-long lag may still be a problem outside the small-plan safe harbor. Document your process and hit the shortest consistent timeline.

Calendar-year plans must also file Form 5500 by the standard deadline or extend properly; if you discover missed filings, using DFVCP before the government contacts you can sharply reduce exposure. The IRS generally waives overlapping penalties for eligible filers who complete DFVCP and meet related IRS conditions (including Form 8955‑SSA where applicable).

Enforcement is active—and rising

EBSA’s most recent results underscore that investigators are busy: in fiscal year 2024, the agency reported hundreds of civil cases closed and significant monetary recoveries for plans and participants, alongside dozens of criminal indictments and convictions tied to plan abuses. That backdrop makes timely self-correction and strong documentation even more critical for fleets.

Action checklist for trucking plan sponsors

Tighten your deposit pipeline. Integrate payroll and recordkeeper funding to deposit employee deferrals as soon as administratively possible—and within seven business days if you qualify as a small plan. Test the process monthly and keep a deposit log.
Reconcile every payroll. After each run, reconcile gross pay, deferrals, employer match, and trust receipts; investigate any gap immediately.
Benchmark fees annually. Review 408(b)(2) disclosures, compare to market benchmarks, and minute fiduciary decisions to retain or change providers.
Keep documents and operations in sync. Amend your plan on time, then verify that day‑to‑day administration (eligibility, match formulas, compensation definitions) matches the written terms.
Mind the filings. Calendar your Form 5500 due date, file (or extend) on time, and, if late, consider DFVCP before an agency notice lands. Coordinate any IRS requirements tied to DFVCP to lock in penalty relief.
Prepare for questions. If contacted by DOL or IRS, respond promptly and involve an ERISA‑savvy advisor. Early cooperation can narrow scope and shorten disruptions.

Bottom line

KLR’s six‑point list is a practical roadmap for trucking employers who want to stay off the enforcement radar. Focus on fast, documented deposits; accurate, on‑time filings; vigilant fee oversight; and clean operations that match your plan document. Those steps will reduce audit risk, protect participants, and keep your fleet’s benefits program running as smoothly as your best-performing lane.
