Form 5500 Filing Requirements for Small Employer Health Plans

Form 5500 filing requirements for small employer health plans depend on ERISA coverage, how the plan is set up, its participant count, and how it is funded, as well as the employer’s size. A plan with fewer than 100 participants may qualify for an exemption, but only if its funding arrangement meets the applicable conditions. Filing obligations, applicable forms and schedules, and penalties for overlooked obligations depend on these conditions.

What Form 5500 is and why ERISA requires it for health and welfare plans

Form 5500 is an annual report filed with the Department of Labor (DOL) for employee benefit plans subject to ERISA’s reporting requirements. The 2025 Form 5500 instructions call for reports that include participant counts, insurance information, broker commissions, and financial information on plan assets. The report serves compliance, research, and disclosure purposes. It is not an internal record alone. The DOL’s EFAST2 FAQ states that submitted filings are posted for public access, giving inaccuracies both regulatory and reputational consequences.

ERISA applies to virtually all private-sector employers, including corporations, partnerships, LLCs, sole proprietorships, and nonprofits, regardless of size. Governmental employers and non-electing churches are categorically excluded, while statutory exclusions also cover certain plans, including those maintained solely to comply with workers’ compensation, unemployment, or disability laws. Plans maintained outside the United States primarily for nonresident aliens are also excluded. For covered health and welfare plans, reporting exemptions require a separate analysis. The 2025 instructions require electronic filing through EFAST2 and do not permit paper filing by mail.

Which private-sector employers are exempt from filing — and the precise conditions each exemption requires

The principal filing exemption for small private-sector employers applies to qualifying health and welfare plans with fewer than 100 participants on the first day of the plan year. The plan must be unfunded, fully insured, or a qualifying combination of insured and unfunded. All three variables require examination, count, structure, and funding. An employer’s total workforce does not establish the exemption, and neither does the enrollment total for its medical coverage viewed in isolation.

“Unfunded” is a technical ERISA classification. It describes benefits paid solely from the employer’s general assets rather than through a trust or separate pool of plan assets. Employee contributions also require attention in this analysis. Their presence prevents an employer from assuming that benefits come solely from general assets, although a fully insured arrangement may qualify under the insured or combination exemption.

A separate exception to small-plan relief concerns multiple employer welfare arrangements, or MEWAs. A MEWA or arrangement subject to Form M-1 requirements cannot rely on the exemption regardless of participant count or funding method. For employers participating in association health plans or industry group arrangements, the arrangement’s status controls this question regardless of the individual employer’s headcount.

How to count participants correctly — the rule dependents don't count, and the rule COBRA enrollees do

The participant count includes active employees who are enrolled now, former employees enrolled under COBRA, people eligible for COBRA who have not yet chosen coverage, and retirees who are covered. Spouses, domestic partners, and dependent children are excluded, even when they receive coverage. They are beneficiaries for this threshold. As a result, a benefits system’s total covered lives can be much higher than the count used to decide whether Form 5500 is required.

Consider a small tech employer whose plan covers 60 enrolled employees and 80 dependents on the first day of the plan year. Assuming no additional participants in the other counted categories, its participant count is 60 out of 140 covered lives. The dependents do not change the filing threshold. If the plan is otherwise eligible for the small-plan exemption, that opening-day count supports the exemption for the year. Growth above the threshold later in the year does not change that result until the next plan year’s count is taken.

The practical recommendation is to reconcile payroll records with enrollment data rather than use an enrollment system’s headline total. That check must separate employees from dependents and keep former employees and retirees who count in the total. “Employee-only” is therefore an incomplete shortcut if it means current payroll alone. Both overcounting dependents and omitting COBRA participants can produce the wrong filing decision.

How wrapped plans change the participant count — and why a plan with fewer than 100 enrollees per line of coverage can still trigger a filing obligation

A wrap document can combine several benefit lines into a single ERISA plan. When it does, the threshold applies to unique participants enrolled in any part of that combined plan across medical, dental, or vision coverage. Plan structure comes before the enrollment calculation. An employee enrolled only in dental counts toward the wrapped plan’s total even if the employee turned down medical coverage, while someone enrolled in more than one wrapped benefit counts once.

A plan might have most employees enrolled in medical, a smaller dental group containing employees without medical coverage, and a further vision group enrolled in neither other line. Each line can have fewer than 100 participants while the count of unique participants across the wrap is above the threshold. Using only the medical roster would miss the need to file.

Separate ERISA plans produce a different result. When each benefit has its own plan document and plan number, the employer evaluates the threshold separately for each plan. That approach requires more plan documents but may preserve the small-plan exemption for individual lines. The distinction depends on the actual documents regardless of whether enrollment materials present the benefits as separate choices.

How the plan's funding method determines whether the small-plan exemption is available at all

Check whether benefits come from the employer’s general operating funds or involve a trust, employee contributions, or a separate asset pool. Commercial labels do not answer that question. An arrangement described as self-funded or level-funded can require a different ERISA analysis from the one its everyday name suggests.

A fully insured plan whose employer pays all premiums from general operating funds, without employee contributions or a trust, can be unfunded in the ERISA sense. Employee premium contributions change that analysis because plan assets are involved. That does not automatically establish a filing obligation. The plan may still qualify through the insured or combination insured/unfunded exemption, so treating every payroll deduction as a conclusive filing trigger would bypass an available exemption analysis.

Self-funded and level-funded arrangements often have claims accounts, stop-loss reimbursement structures, or reserves held by the employer that must be checked to see whether the plan has funded status. For small tech employers adopting level-funding to control costs, this is a particularly easy obligation to overlook. Holding assets apart from the employer’s general funds may keep the arrangement from qualifying for small-plan relief.

HRAs and ICHRAs illustrate the reverse distinction. They are self-funded by definition and subject to ERISA reporting requirements, but they can qualify for the small-plan exemption when below the participant threshold and without assets held in trust. In that setting, they are treated as unfunded.

Which form to file and which schedules apply once a filing obligation is confirmed

Once an obligation exists, participant count and asset conditions determine the choice between Form 5500 and Form 5500-SF. Plans below the threshold can use the short form if they meet the eligible-plan-asset standard. Eligible assets include mutual funds, insurance contracts, publicly traded securities held by a broker-dealer, cash, and participant loans. Real estate and private company stock do not qualify. Plans with 100 or more participants, and small plans that fail the eligible-asset test, must use the full Form 5500.

For full-form health and welfare filings, Schedule A reports insurance information when an insurance contract provides benefits. It includes premiums, carrier information, and broker or agent commissions. Those commissions therefore enter the public record. Financial reporting generally follows plan size and funding, with Schedule H applying to large plans and Schedule I to small funded welfare plans. Unfunded small plans typically attach neither financial schedule.

Self-funded or level-funded plans without insurance contracts generally do not file Schedule A, although their size and funding structure may require Schedule H or I. A wrap plan instead submits one Form 5500 covering its combined benefits, with attachments for each line that requires them. Each insured line, for example, requires its applicable Schedule A. The single filing does not eliminate the need to account for the distinct benefits within it.

Filing deadlines, the extension process, and how a final filing works when a plan terminates

The standard filing deadline is the last day of the seventh month after the plan year ends. For a calendar-year plan covering the 2025 plan year, that date is July 31, 2026. Timeliness is a separate requirement from accuracy. A complete filing submitted after the applicable deadline can still expose the plan administrator to penalties.

A one-time extension of two and a half months is available through Form 5558, filed by the original due date. For the 2025 calendar plan year, the extended deadline is October 15, 2026. An automatic extension can also apply when the plan sponsor’s federal income tax return deadline is extended and specified conditions are met. In that case, no separate extension form is required.

Changes in sponsorship require their own attention. When an employer leaves a PEO midyear and becomes the sponsor of a standalone plan, the employer assumes the new plan’s applicable filing obligations, including any filing due for that year. When a plan ends, the employer must also work with the service provider to check the rules for that plan’s final filing as well as its enrollment count.

Penalties for missing or late filings, and the DOL's voluntary correction program for delinquent filers

The DOL can impose large civil penalties for each day that a required filing has not been submitted in full. The 2025 instructions describe penalties under ERISA section 502(c)(2) that are adjusted for inflation. Reasonable cause may support a waiver, but the standard is narrow and the DOL—not the employer—decides whether it is met.

The DOL’s Delinquent Filer Voluntary Compliance Program (DFVCP) provides a route to reduced penalties for administrators who correct missed filings voluntarily. Its availability depends on timing. Required filings must be made before written DOL notification of the failure to file, after which the program is no longer available. Penalties through voluntary correction are significantly lower than those that can follow DOL enforcement. For employers with delinquent filings, the recommended action is to use DFVCP before the DOL acts rather than defer correction in anticipation of a reasonable-cause waiver.

A decision framework for small employers: how to work through the filing question in the right order

The practical sequence begins with ERISA coverage, followed by plan structure, participant count, and funding. Governmental employers and non-electing churches can stop at the coverage question, while other private-sector employers go on unless an exclusion applies to their plan. Documents establish the unit being evaluated. A wrap means counting unique participants across its benefits, whereas separate plans require separate counts.

For each identified plan, the next step is to establish the first-day participant count from enrollment and payroll records, including the applicable COBRA categories and covered retirees but excluding dependents. For a below-threshold plan to qualify for relief, its funding must meet the applicable conditions, so the analysis must distinguish general-asset payments from trusts, employee contributions, and separate claims accounts without overlooking the insured or combination exemption. They must also check MEWA and Form M-1 status, which can rule out small-plan relief whatever the earlier checks show.

Only after those questions are resolved does the process turn to the form, schedules, and filing deadline. A broker, third-party administrator, or compliance consultant specializing in ERISA health and welfare plans can reduce misclassification risk, particularly where wrap documents or funding arrangements are ambiguous. Calendar-year plan sponsors should work with their providers to file electronically by July 31, 2026, unless an extension applies and changes the deadline.
