ACA Compliance for Level Funded Plans: What Applies, What Does Not, and Where the Confusion Lives

The Affordable Care Act created different requirements for different market segments. Large group, small group, individual, and self-funded plans face distinct regulatory frameworks. Self-funded plans are exempt from many ACA requirements that apply to fully insured plans: community rating, essential health benefits mandates, medical loss ratio requirements. But self-funded plans are not exempt from everything. The employer mandate applies to applicable large employers. Reporting requirements apply to all group health plan sponsors. Certain consumer protections apply regardless of funding arrangement. The confusion arises because the boundaries are not intuitive, and both employers and advisors sometimes assume self-funded means ACA-exempt across the board. This under-compliance creates regulatory exposure. Conversely, some self-funded plan sponsors over-comply with ACA provisions that do not apply, increasing cost without legal necessity.

What Does Not Apply

#

The ACA exemptions that create the level funded economic advantage are substantial. Understanding them explains why healthy small groups leave the fully insured market for level funded.

Community rating does not apply to self-funded plans. The ACA requires fully insured small group plans to use modified community rating: carriers may adjust premiums only for age, geography, tobacco use, and family size. They cannot adjust for health status, claims history, or industry. Self-funded plans, including level funded, are not subject to community rating. Stop loss carriers underwrite small groups using health status, claims history, industry classification, and other factors that fully insured carriers cannot use. A 20-person professional services firm with young, healthy employees and no significant claims history receives stop loss quotes reflecting its favorable risk profile. The equivalent employer in the fully insured market receives a community-rated premium that cross-subsidizes sicker groups. The difference in premium can be approximately 20% to 40% for favorable risks, depending on group size, demographics, and claims history. This difference is the primary economic driver of the level funded market.

Essential health benefits mandates do not apply to self-funded plans. The ACA requires fully insured small group and individual market plans to cover ten categories of essential health benefits: ambulatory services, emergency services, hospitalization, maternity and newborn care, mental health and substance use disorder services, prescription drugs, rehabilitative services, laboratory services, preventive and wellness services, and pediatric services including dental and vision. Self-funded plans are not required to cover these categories. The plan sponsor designs the benefit through the plan document.

The practical effect of the EHB exemption is more limited than it appears. Most level funded plans cover benefits comparable to essential health benefits because competitive positioning demands it. An employer cannot attract and retain employees with a plan that excludes maternity coverage, mental health services, or prescription drugs. The exemption provides design flexibility at the margins: the ability to exclude certain services, impose different cost-sharing structures, or design benefits outside the EHB framework. It does not provide license to offer bare-bones coverage in a competitive labor market.

Medical loss ratio requirements do not apply to self-funded plans. The ACA requires fully insured carriers to meet minimum medical loss ratios: 80% for small group, 85% for large group. Carriers that fail to meet these thresholds must rebate premium to policyholders. MLR requirements do not apply to self-funded plans. The level funded plan’s economics are governed by the claims fund, stop loss premium, and administrative fee structure, not by MLR regulation. The TPA does not have a medical loss ratio. The stop loss carrier’s loss ratio is a market dynamic, but it is not subject to ACA MLR rules.

The single risk pool requirement does not apply to self-funded plans. The ACA requires fully insured small group and individual market carriers to pool all enrollees into a single risk pool for rating purposes within each market segment. Self-funded plans are not part of the state risk pool. Each employer’s plan is its own risk unit. This exemption allows level funded employers to benefit from their own favorable claims experience rather than cross-subsidizing other groups in a pooled market.

What Does Apply

The requirements that apply to self-funded plans create compliance obligations that many small employers miss.

The employer shared responsibility provision applies to applicable large employers. An ALE, defined as an employer with 50 or more full-time equivalent employees, must offer minimum essential coverage to full-time employees or face penalties under IRC Section 4980H. The mandate applies regardless of funding arrangement. A self-funded ALE must offer coverage that meets minimum value and affordability standards to avoid penalties.

Most level funded employers are under 50 lives and are not ALEs. The typical level funded plan sponsor in the 6-to-25 employee range has no employer mandate obligation. But employers near the 50-FTE threshold must track employee counts carefully. An employer at 48 FTEs who adds two employees becomes an ALE. An employer who hires seasonal workers may be an ALE during certain months. The determination is complex for employers with variable hours, part-time employees, or multiple business entities.

Reporting requirements apply to all self-funded plan sponsors regardless of employer size. IRC Section 6055 requires providers of minimum essential coverage to report coverage information to the IRS and furnish statements to covered individuals. Self-funded plan sponsors are the reporting entity for Section 6055. A 10-person level funded plan sponsor must file Forms 1094-B and 1095-B reporting the coverage provided to each covered individual. Failure to file is subject to penalties, which are assessed per return. An employer who fails to file required returns for 50 covered individuals (including dependents) faces penalties that multiply quickly.

IRC Section 6056 applies to ALEs, requiring information about the coverage offered, whether it meets minimum value and affordability standards, and which employees were offered coverage. Self-funded ALEs must file Forms 1094-C and 1095-C. Non-ALE employers do not have Section 6056 reporting obligations, but all self-funded plan sponsors have Section 6055 obligations.

Preventive care coverage requirements apply to all group health plans including self-funded. The ACA requires group health plans to cover recommended preventive services without cost-sharing: no deductible, no copay, no coinsurance for covered preventive services. The requirement covers immunizations recommended by the Advisory Committee on Immunization Practices, screening tests recommended by the U.S. Preventive Services Task Force, preventive care for women recommended by HRSA, and preventive care for children and adolescents. Self-funded plans that impose cost-sharing on covered preventive services violate federal law regardless of plan design flexibility under ERISA.

Other ACA provisions apply to self-funded plans. Lifetime and annual dollar limits on essential health benefits are prohibited. Coverage of dependents up to age 26 is required. Rescission of coverage except for fraud is prohibited. Internal and external appeals processes meeting federal standards are required. Summary of Benefits and Coverage documents must be distributed. These requirements constrain self-funded plan design just as they constrain fully insured plan design.

Where Confusion Creates Risk

#

The boundary between what applies and what does not creates compliance errors in both directions.

Under-compliance occurs when employers or their advisors assume self-funded means ACA-exempt across the board. An employer who does not file Section 6055 reports is in violation. The IRS assesses penalties per return. For a 20-person group with 50 covered individuals including dependents, the employer faces penalties for 50 unfiled returns. The employer who did not know the requirement existed learns about it when the IRS sends a penalty notice.

An employer whose plan applies deductibles to preventive care services is in violation. The ACA requires first-dollar coverage of covered preventive services in all group health plans. A level funded plan that charges a copay for a preventive screening or applies the deductible to a covered immunization violates federal law. The employer may believe the plan design reflects their authority to design benefits without EHB compliance. They are wrong about preventive care.

An employer who does not distribute Summary of Benefits and Coverage documents is in violation. The SBC requirement applies to self-funded plans. The TPA typically produces the SBC, but the plan administrator (the employer) is responsible for distribution. An employer who relies on the TPA to distribute and the TPA does not is the party in violation.

Over-compliance occurs when employers or their advisors apply fully insured requirements to self-funded plans. An employer or TPA that designs the plan to comply with essential health benefit requirements when EHBs do not apply increases cost without legal necessity. The employer who could exclude a service or structure a benefit differently is instead complying with requirements that do not apply.

An employer or TPA that applies state mandated benefit rules when ERISA preemption exempts the plan is adding cost. If the state requires coverage of a specific provider type in fully insured plans, the self-funded employer may not be required to cover it under state law. Applying the state mandate adds plan cost.

An employer that pays state premium taxes when the plan is self-funded and ERISA-preempted is paying taxes not owed. Self-funded plans are not subject to state premium taxes because the employer is not purchasing insurance. Some employers make premium tax payments because they or their advisors do not understand the exemption.

The Small Employer ACA Interface

#

Level funded plans in the 1-to-50 employee segment interact with the ACA in specific ways.

Employers under 50 full-time equivalent employees are not applicable large employers. They have no employer mandate obligation. They can choose to offer coverage or not. They can choose level funded, fully insured, ICHRA, or no group coverage at all. The ACA does not penalize them for offering no coverage. The ACA does penalize them if they offer coverage that violates applicable provisions.

The PCORI fee applies to self-funded plan sponsors. The Patient-Centered Outcomes Research Institute fee is assessed annually per covered life. For plan years ending between October 2023 and September 2024, the fee was $3.22 per covered life; for plan years ending between October 2024 and September 2025, the fee is $3.47 per covered life. The fee is modest but represents an administrative obligation requiring accurate enrollment tracking and timely filing on IRS Form 720. Non-payment is subject to IRS penalties. The employer who does not know about the PCORI fee discovers it when they fail to pay it.

The transitional reinsurance fee that applied to self-funded plans from 2014 through 2016 no longer applies. Employers and advisors who believe they still owe reinsurance fees are misinformed. The program ended. No fees are owed for plan years after 2016.

The Compliance Posture

#

A level funded plan sponsor should understand which ACA provisions apply and ensure compliance with those provisions while not over-complying with provisions that do not apply.

The employer should confirm that Section 6055 reporting is being performed. If the TPA handles reporting, the employer should verify that filings are made timely and accurately. If the employer handles reporting internally, the employer must have systems to track covered individuals, generate required forms, and file with the IRS.

The employer should review the plan document and SBC to confirm that covered preventive services are provided without cost-sharing. If the TPA drafted the plan document, the employer should verify compliance. A plan design that complies requires specific enumeration of covered preventive services and first-dollar coverage for those services.

The employer should confirm that the plan meets dependent coverage, lifetime limit, rescission, and appeals requirements. These requirements constrain plan design. A plan document that permits rescission for reasons other than fraud violates federal law. A plan document that imposes lifetime limits on essential health benefits violates federal law.

The employer should not assume that the TPA or broker has ensured compliance. The employer is the fiduciary. The employer bears regulatory responsibility. The TPA provides services. The broker provides advice. Neither is the fiduciary of the plan. An employer who delegates compliance oversight without verification accepts risk if compliance fails.
