DOL letter about a missing Form 5500 — the first 30 days

Three agencies touch a Form 5500 and each writes differently. The letterhead and the title line decide everything that follows.

• EFAST2 filing-status messages. System messages, not penalty letters. A submission in Filing_Error or Filing_Stopped status must be fixed with an amended filing; the DOL's EFAST2 FAQ warns that leaving it invites “Agency correspondence,” and it counts as not filed.
• EBSA Inquiry Letter or Notice of Rejection. From EBSA's Office of the Chief Accountant when a filing exists but is incomplete. The inquiry letter gives 10, 15, or 30 days; the Notice of Rejection gives 45 days (ERISA §104(a)(5)), and under 29 CFR 2560.502c-2(b) a rejection not cured in 45 days is treated as never filed.
• EBSA Notice of Intent to Assess a Penalty (NOI). The one that matters. For a non-filer, EBSA's manual says the NOI “may be the first correspondence” you receive, with no warning letter before it. It must state the intent to assess, the amount, the period, and the reasons (2560.502c-2(c)). It starts the reasonable-cause clock and it ends DFVCP eligibility for the years it covers.
• EBSA Penalty of Perjury letter. Issued when your NOI response arrived without the required declaration under penalties of perjury. You get 10 days to fix it; if nothing is postmarked by day 10, the NOI becomes a final penalty.
• EBSA Notice of Determination (NOD). The decision on your reasonable-cause statement: no penalty, partial waiver, or no waiver. It becomes a final order 45 days after service unless, within 30 days, you request a hearing before an administrative law judge and file a written answer (2560.502c-2(g), (h)).
• IRS CP403 and CP406. Return delinquency notices for the Form 5500 series, mailed 15 months after the original due date (CP403) and 15 weeks after an unanswered CP403 (CP406). In the IRS's words, “They aren't bills.” They ask for a return or an explanation within 30 days, with no extensions.
• IRS CP283. “Penalty Charged on Your Form 5500 Return.” This one is a bill, and it closes the IRS's own 5500-EZ relief program for that return.

The second column comes straight from the DOL's DFVCP FAQ: “An IRS late-filer letter will not disqualify a plan from participating in the DFVCP. A Department of Labor Notice of Intent to Assess a Penalty will always disqualify a plan.” The rest of the eligibility rules are in DFVCP eligibility.

29 CFR 2560.502c-2 sets the sequence. The administrator has 30 days from the date of service of the notice to file a written statement of reasonable cause. Service is complete on mailing for certified mail and on receipt for regular mail, and the regulation adds five days to the response period when the notice goes by certified mail, which is why EBSA's letters usually say 35 days. The manual is blunt: “There is no extension of time to the 35 day period.”

If no statement is filed in time, the regulation treats that as a waiver of the right to contest the facts in the notice and an admission of them, and the NOI becomes a final order 45 days after service. Internally, the analyst completes a Final Order Checklist on day 45 and the file goes to collection; the administrator has also lost the right to an ALJ hearing. If a statement is filed, the penalty stops accruing from service of the NOI until the day after the Notice of Determination, and the Reasonable Cause Committee reviews the case before the NOD issues.

Your statement counts as filed on mailing only if it goes USPS certified or Express Mail (or a designated private delivery service); by any other method it is filed on receipt. Send it certified and keep the receipt.

1. Day 0 — read it twice and calendar the deadline. Note the agency, the title line, the plan number and EIN, the plan years named, the amount, the letter date, and how it was delivered. Count 30 days from service (35 for certified) and put that date, plus a day-25 check, on the CFO's and HR director's calendars. Send the letter to counsel and the TPA the same day. Do not call EBSA for more time; the answer is no and the call does not stop the clock.
2. Days 1–5 — confirm the plan facts and whether a filing was actually due. Pull the plan document and the participant count at the start of each named year. A welfare plan with fewer than 100 participants that is unfunded, fully insured, or both is exempt under 29 CFR 2520.104-20; if that is you, the response is an explanation, not a filing. Check EFAST2 under the exact EIN and plan number on the letter, since a plan-number mismatch is a common cause of an IRS CP403 (a return filed in the last four weeks under matching numbers means you may ignore the notice). Then run the sponsor through the Late-Filing Penalty Check to see every welfare Form 5500 on the public record and any gaps the letter did not mention.
3. Days 5–15 — file through EFAST2, or decide DFVCP. For an IRS-only letter this is a DFVCP cure: rebuild the year, check the DFVC box, pay at askebsa.dol.gov/dfvcepay, and follow the DFVCP cure timeline. For a DOL NOI, file the same way but without the DFVC box for the years named (DFVCP FAQ Q12: a Notice of Intent “will always disqualify a plan” for those years), and use DFVCP for any late year the NOI did not name. Request Schedule A data from every carrier on day 5; a complete filing on record before the statement goes in is the strongest fact you can put in front of the Reasonable Cause Committee.
4. Days 15–30 — write the reasonable-cause statement and respond. The statement must set out all the facts relied on, be signed by the plan administrator (or a duly authorized power of attorney, with the executed power-of-attorney form attached; the manual gives IRS Form 2848 as an example), and carry a declaration that it is made under the penalties of perjury. Attach each EFAST2 acknowledgment. For an IRS notice, complete Section I of the CP403 or CP406 and send it to the Ogden address on the notice with the DFVCP confirmation. Mail everything certified by day 28 and keep proof.

The regulation does not define the phrase. What it says, in 2560.502c-2(d), is that the Department may decide not to assess all or part of the penalty on a showing that the administrator complied with the annual-report requirement of ERISA §101(b)(1), or on a showing of mitigating circumstances regarding the degree or willfulness of the noncompliance. The amount itself is set by “the degree and/or willfulness” of the failure (2560.502c-2(b)). The Form 5500 instructions put the burden on the filer: penalties apply “unless it is determined that your failure to file properly is for reasonable cause.”

EBSA's enforcement manual describes what its analysts actually weigh. The reasonable cause analysis summarizes the deficiencies, the administrator's arguments for abatement, whether the filing is in compliance on the date of the analysis, and the plan's past and subsequent reporting history, and makes a recommendation to the Reasonable Cause Committee, an advisory body. The manual also confirms that for a non-filer the analyst checks that all requested filings were submitted, not just the years penalized, before any abatement.

So a statement that fits the standard has four parts: why the year was missed; why that was not willful (a TPA, broker, or payroll change with no handoff; a misapplied small-plan exemption; a plan number mismatch; the departure of the person who owned the calendar); what has now been filed, with acknowledgments; and what prevents a repeat. What does not fit: arguing the filing was not required when it was, citing cost or inconvenience, and, in EBSA's one published example, “waiting too long before taking the steps necessary to file electronically,” which the EFAST2 FAQ says “would not be considered reasonable cause.” Reliance on a vendor is worth stating, but the administrator remains liable under ERISA §3(16)(A) and the committee looks at the plan's record, not the vendor's.

Take a calendar-year, fully insured medical plan with 240 participants that never filed for plan years 2022, 2023, and 2024. Due dates were July 31, 2023, July 31, 2024, and July 31, 2025. A Notice of Intent dated October 5, 2026 arrives by certified mail; the response is due November 9, 2026, and silence makes it final on November 19. Days late at the NOI date: 1,162, 796, and 431.

• Statutory ceiling, $2,739 a day: about $3.18 million, $2.18 million, and $1.18 million. EBSA has the authority; it does not use it as the opening number.
• What the NOI is likely to say, using the manual's method: $300 a day up to $30,000 per year of delinquency for each unfiled year. Counting every started year at the full $30,000, that is $120,000 for 2022, $90,000 for 2023, and $60,000 for 2024; counting the 66-day stub year at $300 a day instead gives $239,400. Either way the cumulative figure is above the $180,000 that the manual says is “in most cases” the ceiling.
• What DFVCP would have cost had you filed a week before the letter: $2,000 per filing, capped at $4,000 for the plan.
• After a timely reasonable-cause statement with all three years filed: the manual's abatement guideline is “DFVC x 2,” adjusted “up or down depending on facts and circumstances.” Read literally against this example, that points to a reduced penalty on the order of $8,000 rather than $180,000. It is a guideline in an internal manual, not a rule you can cite, and it is only reachable through a proper, timely statement.
• Had the filing gone in after the due date but before any letter: the late-filer rate is $50 a day with no cap, which for the 2024 year alone would be $21,550 at the NOI date, against $2,000 under DFVCP.
• IRS side: none for this welfare plan; the IRS notices page lists welfare plans as subject to the DOL penalty only. The same three-year miss on the sponsor's 401(k) would add up to $150,000 per plan year under IRC §6652(e), unless cured through DFVCP with the automatic IRS relief.

The 2025 plan year (due July 31, 2026, or October 15, 2026 on extension; see the Form 5500 due date) is not on this NOI. If it is also late, it is still DFVCP-eligible and should be filed under the program the same week. Under DFVCP FAQ Q15, every dollar in this section is the plan administrator's personal liability and cannot be paid from plan assets.

EBSA's analyst checked EFAST2 and the public disclosure system before writing to you, and the committee will look at the plan's whole reporting history. Look at the same record first. The Late-Filing Penalty Check walks every welfare Form 5500 filed under your sponsor's EIN, flags gaps and late years, and puts DOL, IRS, and DFVCP exposure side by side. The employer index is the fastest way to find a filing made under a predecessor name or a different plan number. Years missing that the letter does not name are still DFVCP years; file them before EBSA writes again.

An IRS CP403 for a year you can cure under DFVCP in a few weeks is usually a TPA-and-broker job with counsel copied. Bring ERISA counsel in on day 0, not day 20, when the letter is a DOL Notice of Intent; the amount is in six figures; the plan held trust assets and an audit opinion is missing; the plan-size or exemption facts are arguable; a vendor's failure is the cause and indemnity is in play; or you may want a hearing after a Notice of Determination, which runs under 29 CFR 2570.60 through 2570.71 with deadlines of its own. Counsel should draft or review the reasonable-cause statement: it is made under penalties of perjury and it is the one document the committee reads.

Can I still use DFVCP for a year the DOL letter does not mention?

Yes. The disqualifier is written notice of a failure to file for a given year. Years the NOI does not name are still eligible, and the manual's abatement review expects to see every requested year filed, so file them under the program at the same time.

Does the IRS letter close DFVCP?

No. The DOL program page and FAQ both say an IRS late-filer letter does not disqualify a plan. A CP283 penalty notice closes the IRS's own 5500-EZ relief program for that return, but a Title I plan does not use that program; it gets IRS relief automatically by completing DFVCP under Notice 2014-35.

Can I ask EBSA for an extension to respond to the NOI?

No. The manual states there is no extension of time to the response period. An analyst may telephone the administrator around day 25 to confirm receipt and remind you of the deadline; that call is not an extension.

Can I file under DFVCP and still argue reasonable cause?

No. DFVCP FAQ Q20: paying under the program waives both the right to a notice of assessment and the right to contest the amount. If you want to argue reasonable cause, you file in the regular manner and respond to the NOI. For an eligible plan the DFVCP fee is almost always the cheaper path.

Does the penalty keep growing while EBSA reviews my statement?

Not during the review. Under 2560.502c-2(b), no penalty accrues for the period from service of the NOI until the day after the Notice of Determination. It does keep running from the original due date up to the NOI date, which is why filing before the letter arrives is worth so much.

• Identify the letter by agency and title, and calendar 30 days from service (35 if certified) with a day-25 internal checkpoint.
• Run the Late-Filing Penalty Check and list every missing or late plan year by plan number, including years the letter does not mention.
• Send Schedule A requests to every carrier today and get every missing year into EFAST2 before the statement goes in: DFVCP for unnamed years, regular filing for years on a DOL NOI.
• Have counsel draft the reasonable-cause statement with the penalty-of-perjury declaration, signed by the administrator, and send it certified before day 28.
• Fix the calendar: assign Form 5500 ownership by name and put July 31 and October 15 on next year's compliance calendar now.
