Most plan sponsors review the Form 5500 for about ninety seconds. It arrives as a PDF from the TPA or recordkeeper, someone in finance forwards it with “sign here,” and it gets signed. If you want to review Form 5500 before signing the way the signature actually asks you to, that ninety seconds is not close to enough — because the person who signs is personally attesting, under penalty of perjury, that the return is true, correct and complete to the best of their knowledge.
This post is not about who signs the Form 5500 — that question has its own answer. This one is about what you are supposed to look at before you sign, what happens when a wrong answer goes out under your name, and the option most sponsors do not know they have: having someone else be responsible to sign it.
What signing the Form 5500 legally means
The Form 5500 is a joint filing under ERISA and the Internal Revenue Code. The plan administrator signs it electronically through EFAST2 using credentials tied to a named human being. That signature is not an administrative formality and it is not transferred by the fact that a service provider prepared the return.
Three things follow from that:
- The preparer’s work does not become the preparer’s liability. Whoever signs owns the answers.
- “The recordkeeper filled it in” is not a defense to an inaccurate return.
- Because the return is a disclosure document, the DOL and IRS both use it as a screening tool. Answers that look inconsistent invite correspondence, and correspondence sometimes becomes an examination.
So the practical question for any employer is simple: before your name goes on it, did anyone actually reconcile the return against the plan’s own records?
The pre-signature review checklist
Work through these in order. Every item is something you can check against documents you already have — the trust statement, the payroll register, the plan document and last year’s filing.
1. Participant counts at the beginning and end of the year
Participant counts drive more downstream consequences than any other number on the form. They determine whether the plan files as a small or large plan, whether an independent audit is required, and whether the plan’s filing history looks stable. Tie the counts back to your eligibility rules — not to a headcount report. If your eligibility and entry date provisions were applied inconsistently during the year, the participant count on the return inherits that error.
2. Financial information against the trust statement
Beginning assets, ending assets, contributions, distributions, and expenses on Schedule H or Schedule I should tie to the trust or custodial statement line for line. If contributions on the return do not match what the trust received, one of the two records is wrong, and you are about to certify one of them.
3. The late deferral deposit question
Schedule H/I asks whether participant contributions were transmitted to the plan later than required. This is the single most-reviewed line on the return. Answering “no” when payroll shows otherwise is the kind of inaccuracy that turns a filing into a file. If deposits were late, the correct path is to report them and complete the correction — deposit the principal, restore lost earnings, and consider the DOL’s voluntary correction program. Our walkthrough on correcting late deferral deposits covers the sequence.
4. Service provider and fee information
Schedule C (for large plans) reports service provider compensation, including indirect compensation. Sponsors often sign this without ever comparing it to the 408(b)(2) fee disclosures they received. If you cannot explain how a provider is paid, you cannot certify what the return says about it — and fee reasonableness is a core fiduciary duty you retain regardless of who administers the plan.
5. The audit attachment, if you are a large plan
Large plans must attach an independent qualified public accountant’s report. Confirm the attachment is actually there, that the plan name and EIN match the return, and that any findings in the report are consistent with the answers on the form. A missing or mismatched audit report is a common rejection trigger. Our audit readiness checklist lists what the auditor will want long before the return is due.
6. The compliance questions
The return asks whether the plan failed to provide benefits when due, whether there were prohibited transactions or loans in default, whether the plan was covered by a fidelity bond and for how much, and whether corrective distributions were made. These are yes/no questions with real consequences. Each one deserves a documented answer, not a default.
7. Plan characteristic codes
The characteristic codes describe what kind of plan you run — safe harbor status, automatic enrollment, participant direction, designated Roth contributions and so on. They are copied forward year after year and quietly go stale after an amendment. Read them against the current adoption agreement, especially if you added automatic enrollment and now owe automatic enrollment notices.
8. The prior-year comparison
Put last year’s filing next to this year’s and look for anything that moved without explanation: a jump in participant count, a change in filing size, a new schedule, a dropped schedule, a different plan number. Regulators run exactly this comparison. You should see it first.
What a wrong answer actually triggers — and who eats it
An inaccurate or incomplete Form 5500 can be treated as a filing failure, and the penalty structure for late or deficient filings is designed to be uncomfortable. Beyond penalties, the practical consequences land in this order:
- Correspondence. A letter asking about an inconsistency. Cheap to answer if your records tie out, expensive if they do not.
- Examination. The return becomes the roadmap. Inconsistent answers direct where the examiner looks.
- Correction. Operational failures surfaced by the review must be fixed through the IRS or DOL correction programs, usually with restored earnings.
- Personal exposure. Fiduciary liability under ERISA runs to the individual who held the role, not only the company.
The employee who signed did not create the error. They inherited it from a payroll feed, a stale plan code or a provider’s spreadsheet — and then attested to it.
The other option: don’t be the one who signs
Here is the part most sponsors have never been offered. The signature can move. When a provider accepts the ERISA 402(a) named fiduciary appointment together with full-scope 3(16) plan administration, that provider becomes the plan administrator of record — and the plan administrator is who signs the Form 5500.
That is a genuinely different arrangement from what most vendors sell. Many providers will prepare the return, review it, even walk you through it — and then email it to you to sign. The distinction between the fiduciary roles is worth understanding in full: our breakdown of 3(16) vs. 3(21) vs. 3(38) vs. 402(a) shows where each one starts and stops.
Practically, moving the signature means:
- Someone whose job is ERISA compliance performs the pre-signature review, not your HR generalist in the middle of open enrollment.
- The attestation is made by the party with the compliance record behind it.
- Errors found in the review get corrected as part of the process rather than discovered by a regulator.
- Your internal team keeps oversight — you still receive the return, still review it, still ask questions — without personally certifying it.
What you can never delegate
Delegation is not disappearance. Even with a 402(a) named fiduciary in place, the employer retains the duty to select and monitor its service providers prudently. That means documenting why you chose the provider, reviewing performance and fees on a schedule, keeping committee minutes, and acting on what those reviews show. If you delegate and then never look again, you have replaced one fiduciary failure with another.
A five-minute decision
Pull the last Form 5500 you signed. Ask three questions: Did anyone tie the participant counts to eligibility records? Did anyone compare the financials to the trust statement? Did anyone verify the late deferral answer against payroll? If the honest answer to any of them is “I assume the TPA did,” you signed something you did not review.
Admin316 accepts the 402(a) named fiduciary appointment — the appointment most providers decline — and delivers full-scope 3(16) administration behind it, which means we review the Form 5500 and we sign it. If you would rather that responsibility sit with someone whose profession it is, book a short call and we’ll walk through your last filing line by line.
