IRS Form 5500 is the annual report that most private-sector employee benefit plans must file to satisfy their reporting duties under ERISA and the Internal Revenue Code. A single filing goes to the Department of Labor, the IRS, and the Pension Benefit Guaranty Corporation through the DOL’s electronic filing system.1U.S. Department of Labor. Form 5500 Series Which version you file, which schedules attach, and when it’s due all depend on the type of plan and how many people it covers. Miss the deadline and two agencies can penalize you at the same time, with DOL charges running as high as $2,670 per day and IRS charges up to $150,000 per plan year.
Who Has to File
Form 5500 obligations follow ERISA. If your plan is covered by ERISA, some version of the form is almost certainly required each year. ERISA reaches plans established or maintained by employers or employee organizations engaged in commerce, which pulls in nearly every private-sector retirement and welfare plan in the country.2Office of the Law Revision Counsel. 29 USC 1003 – Coverage That includes 401(k) plans, profit-sharing plans, defined benefit pensions, and many group health, life, and disability arrangements.
The plan administrator is legally on the hook for filing. Often the sponsoring employer serves as administrator, but ERISA treats the two roles as separate, and if the plan document names a different administrator, that party carries the duty.
Small Welfare Plans Are Often Exempt
Welfare plans with fewer than 100 participants that are unfunded or fully insured (they don’t hold assets in a trust) are generally exempt from filing.3U.S. Department of Labor. Changes for the 2023 Form 5500 and Form 5500-SF Annual Return Reports Watch how the count works: “participants” includes every eligible employee whether or not they enrolled, plus former employees and beneficiaries still receiving benefits. Employers who count only enrolled workers routinely discover they should have been filing all along. Any welfare plan holding assets in a trust files regardless of size, and any welfare plan with 100 or more participants always files.
Solo 401(k) Plans and the $250,000 Threshold
A one-participant plan (covering only a business owner and spouse, or partners and their spouses) doesn’t have to file at all until the combined assets of all one-participant plans the employer maintains exceed $250,000 at the end of the plan year.4Internal Revenue Service. About Form 5500-EZ A solo owner with $180,000 in a self-directed 401(k) files nothing. Once the balance crosses $250,000, Form 5500-EZ becomes mandatory every year going forward, and it’s required in the plan’s final year even if assets are below the threshold.5Internal Revenue Service. Instructions for Form 5500-EZ
Which Version of the Form You File
The Form 5500 series has three versions. Filing the wrong one can lead to a rejected return or an incomplete filing that draws penalties.
- Form 5500 is the full version for plans with 100 or more participants at the start of the plan year. It carries the most detailed financial disclosures and usually multiple schedules.
- Form 5500-SF is a short form for small plans (fewer than 100 participants) that meet conditions including holding qualifying plan assets. It cuts the reporting burden significantly for plans with simple investment structures.3U.S. Department of Labor. Changes for the 2023 Form 5500 and Form 5500-SF Annual Return Reports
- Form 5500-EZ is for one-participant retirement plans and certain foreign plans.4Internal Revenue Service. About Form 5500-EZ
The 80-120 Participant Rule
The dividing line between small and large plans is 100 participants, but head counts move. To keep plans from flipping categories every year, the DOL allows an 80-120 rule: if the plan has between 80 and 120 participants at the beginning of the plan year, it can keep whatever filing status it used the year before. A small plan that filed 5500-SF last year can keep doing so until participants hit 121. A large plan stays large until the count drops below 80. This matters because crossing into large-plan territory triggers an independent audit, which typically costs thousands of dollars.
Schedules and the Audit Requirement
The main form captures the basics: asset totals, participant counts (active, retired, separated vested), funding arrangements, and service provider payments. The schedules supply the financial detail. Which ones you need depends on plan type and size.
- Schedule A reports insurance contracts held by the plan, including fees and commissions.6U.S. Department of Labor. Schedule A (Form 5500) Insurance Information
- Schedule C lists every person or entity that received $5,000 or more in compensation for services to the plan.7U.S. Department of Labor. Schedule C (Form 5500) – Service Provider Information
- Schedule H is the comprehensive financial statement required for any plan with 100 or more participants.8U.S. Department of Labor. 2024 Instructions for Form 5500
- Schedule R reports retirement plan data, including distributions and funding information for plans subject to minimum funding standards.9U.S. Department of Labor. Schedule R (Form 5500) Retirement Plan Information
- Schedule G reports loans or fixed-income obligations in default or classified as uncollectible, and nonexempt transactions involving parties in interest.10U.S. Department of Labor. Schedule G (Form 5500) Financial Transaction Schedules
Plans filing as large plans must engage an independent qualified public accountant to audit the plan’s financial statements, and the auditor’s report attaches to the filing.11U.S. Department of Labor. Advisory Council Report on Employee Benefit Plan Auditing and Financial Reporting Models This is where most timing pressure comes from. The audit can’t wrap until the financials are final, and the financials often wait on year-end valuations from custodians. Many administrators file for an extension for exactly this reason.
When Form 5500 Is Due
Form 5500 is due by the last day of the seventh month after the plan year ends.12eCFR. 29 CFR 2520.104a-5 For a calendar-year plan, that’s July 31 of the following year.13Internal Revenue Service. Form 5500 Corner
Filing Form 5558 with the IRS before the original deadline gets you an automatic one-time extension of up to two and a half months. For a calendar-year plan, that moves the deadline to October 15.14Internal Revenue Service. Form 5558 – Application for Extension of Time to File Certain Employee Plan Returns The extension is automatic as long as the 5558 is filed on time and the extended date falls within the allowed window.
A final Form 5500 is required in a plan’s last year even if it would otherwise be exempt, and for one-participant plans that includes years when assets are below $250,000.5Internal Revenue Service. Instructions for Form 5500-EZ
How to File Through EFAST2
Form 5500 and Form 5500-SF must be filed electronically through EFAST2, the DOL’s online portal. Paper versions of these forms aren’t accepted.1U.S. Department of Labor. Form 5500 Series Both the plan sponsor and the plan administrator provide electronic signatures certifying accuracy. New users register for credentials on the EFAST2 site and complete identity verification before they can sign.
Form 5500-EZ is the exception. Filers not otherwise subject to IRS e-filing requirements can file a paper 5500-EZ directly with the IRS.1U.S. Department of Labor. Form 5500 Series Most use EFAST2 anyway because the electronic system produces immediate confirmation.
After submission, EFAST2 generates a notice showing whether the filing was accepted or rejected. A rejected filing has to be corrected and resubmitted before it counts as received. Accepted filings become public records available through the DOL’s disclosure database.
Amending a Prior Filing
Amended returns go through EFAST2 too, but the amendment must be a complete replacement. You can’t submit only the schedules that changed. The whole form, with every required schedule and attachment, must be resubmitted.15U.S. Department of Labor. FAQs on EFAST2 Electronic Filing System For amendments covering plan years 2021 or earlier, use current-year forms and enter the correct plan year in the space provided; certain actuarial schedules (Schedule SB or MB) must use the version matching the original plan year and be attached as PDFs. One-participant plans that were originally filed on paper amend on paper, using the form version that matches the original filing year.
Penalties for Late or Missing Filings
Two federal agencies can assess penalties on the same late Form 5500, and they often do so together.
DOL Penalty
The Department of Labor can assess a civil penalty under ERISA for every day a required filing is overdue. The current inflation-adjusted maximum is $2,670 per day.16U.S. Department of Labor. Fact Sheet: Adjusting ERISA Civil Monetary Penalties for Inflation There’s no statutory cap on the total, so a filing a year late could in theory produce a six-figure charge. The DOL exercises discretion in practice, but the numbers climb quickly.
IRS Penalty
The IRS imposes a separate penalty under Internal Revenue Code Section 6652(e): $250 per day, up to $150,000 per plan year.17Office of the Law Revision Counsel. 26 USC 6652 The penalty applies to incomplete filings too, so a return with blank required fields or missing schedules can draw the same daily charge as no return at all. It can be waived on a showing of reasonable cause.
The two penalties run independently. A filing two months late can trigger both, and paying one agency doesn’t reduce what you owe the other.
If You’re Already Late: Relief Programs
Two programs let late filers cap their exposure by getting current voluntarily.
DOL Delinquent Filer Voluntary Compliance Program
The DFVCP replaces the per-day rate with a flat, capped charge:18U.S. Department of Labor. Delinquent Filer Voluntary Compliance Program
- Small plans: $10 per day, capped at $750 per late filing and $1,500 per plan. Plans sponsored by a 501(c)(3) organization get a $750 per-plan cap.
- Large plans: $10 per day, capped at $2,000 per late filing and $4,000 per plan.
Enrolling in the DFVCP waives your right to contest the penalty amount. It also doesn’t protect against IRS penalties or against penalties under Title IV of ERISA, so it only closes the DOL side.
IRS Program for Late Form 5500-EZ Filers
The IRS runs a separate relief program specifically for one-participant plans that should have filed Form 5500-EZ and didn’t. Eligible filers can submit delinquent returns with reduced or eliminated penalties.19Internal Revenue Service. Penalty Relief Program for Form 5500-EZ Late Filers The IRS First-Time Abate program does not apply to Form 5500 filings, because these returns carry a daily delinquency penalty rather than the standard failure-to-file penalty.20Internal Revenue Service. Administrative Penalty Relief
If you find missing filings, using these programs before either agency comes looking almost always costs less than waiting for enforcement.
