Fractional and Portfolio Workers: The Structurally Uninsured Professional Class

LFP-06.03 | Sharp Analysis | Series 06: The Populations

The fractional CFO earns $200,000 annually from five clients. None of the five offers group health coverage. None employs her full-time. None considers her an employee under ERISA. She is a 1099 contractor to each, collectively working 55 hours per week across the engagements. She has purchasing power. She has demand for quality coverage. She has no pathway to employer-sponsored insurance. The income is not the problem. The structure is.

This is not a gig economy problem, and conflating these two populations is analytically damaging. The gig worker drives for a platform, earns below-median income, and faces coverage gaps for reasons that include affordability alongside structure. The fractional executive, portfolio professional, and multi-client consultant earn substantial incomes and face coverage gaps for reasons that are purely structural. The income can support the premium. The architecture of the ESI system has no mechanism for the worker they are.

Defining the Population

#

The independent workforce is large and internally diverse. The Bureau of Labor Statistics Contingent Worker Supplement, collected in July 2023 and released in November 2024, found that 7.4% of all employed Americans were independent contractors on their sole or main job. Applied to total employment, that represents approximately 12 million workers classified as independent contractors on their primary job. Professional and Business Services was the largest industry concentration, accounting for 24.1% of all independent contractors, up from 21.3% in 2005. The likelihood of being an independent contractor increases sharply with age: 11.5% of workers aged 55 and over were independent contractors, compared to 6.9% of those aged 25 to 54 and 2.2% of those aged 16 to 24. Among all independent contractors, 36% were aged 55 or older.

MBO Partners’ 2024 State of Independence in America survey, covering 72.7 million Americans doing some form of independent work, identified 4.7 million independents earning more than $100,000 annually, up from 3 million in 2020. The 2025 edition placed that figure at 5.6 million, a 19% year-over-year increase. The high-earning segment of the independent workforce is growing faster than the overall independent workforce.

The fractional worker specifically is a professional, typically executive-level or specialized technical, who allocates time across multiple clients or engagements rather than serving one employer. The fractional CFO, fractional CMO, contract general counsel, multi-client consulting partner, and independent technology architect share a structural characteristic: their income is distributed across multiple payers, none of whom individually triggers employer-sponsored insurance eligibility. The portfolio worker differs in engagement pattern but not in coverage consequence: the filmmaker earning from production contracts, grants, and residuals; the architect working discrete projects for multiple firms; the software developer building products under multiple contracts. The structure varies. The coverage problem is identical.

The defining characteristic of this population, for insurance purposes, is multi-source primary income. Not side income. Not supplemental income. Primary income distributed across multiple payers, none of whom individually creates a plan sponsor under ERISA.

Why the ESI System Excludes Them

#

The exclusion is architectural. The mechanisms are specific and interlocking, which is why administrative workarounds cannot resolve the problem.

ERISA defines a plan sponsor as the employer or employee organization that establishes or maintains the plan. An employer that engages a fractional executive on a 1099 basis is not her employer under ERISA. The contractor relationship produces no plan sponsor. No employer exists to establish a group health plan. Even if one client wanted to offer group coverage to its fractional workers, it would need to treat them as employees, which most corporate legal and tax functions will not permit given independent contractor classification requirements.

IRS rules on employer-sponsored coverage eligibility require full-time status, generally 30 or more hours per week, with a single employer. A fractional executive who works 12 hours per week for each of four clients works 48 hours per week in aggregate but zero hours for any single employer. No client has a coverage obligation. The hours threshold is per-employer, not per-worker.

Group health plan formation requires a group. A single fractional worker is not a group. Ten fractional workers serving the same client are not a group under ERISA; they are ten independent contractors with a common customer. The aggregation mechanisms that could theoretically pool fractional workers into a group each carry limitations that exclude this population in practice.

Professional employer organizations co-employ workers, making the PEO the employer of record for benefits purposes. The model works for workers willing to be reclassified as W-2 employees of the PEO. Fractional professionals who have structured their practices as independent contracting for tax, liability, and flexibility reasons are frequently unwilling to accept PEO co-employment, and many of their clients’ legal teams prohibit the reclassification for contractor engagement risk reasons.

Association health plans, expanded by a 2018 Department of Labor final rule to allow bona fide associations to offer group coverage to members including self-employed individuals, face two limiting problems. The 2018 rule was challenged in federal court; the U.S. District Court for the District of Columbia vacated key provisions in 2019, and subsequent regulatory treatment has been uncertain. Carrier appetite for AHP risk has remained limited. The professional associations that serve high-earning independent workers have not developed AHP products that serve this population at the coverage quality and premium levels these workers expect.

Multi-employer welfare arrangements under ERISA Section 3(40) can pool multiple employers for benefit purposes. They require a bona fide employer group and face regulatory complexity at the state insurance department level. They do not provide a mechanism for workers, rather than employers, to pool coverage.

The Coverage Options and Their Inadequacy

#

The ACA marketplace provides individual coverage regardless of employment arrangement. A fractional executive can purchase a plan on-exchange or off-exchange. For household income above 400% of the federal poverty level, approximately $60,240 for a single individual in 2024, no premium subsidies apply. An independent professional earning $200,000 pays full unsubsidized premiums at age-rated individual market rates.

The BLS Contingent Worker Supplement provides the coverage consequence directly: 74.2% of independent contractors had health insurance from any source in July 2023, compared to 84.9% of workers in traditional W-2 arrangements. The gap of 10.7 percentage points represents millions of workers without coverage at all. Among those with coverage, independent contractors are largely purchasing individual market coverage rather than receiving employer-sponsored group coverage, and the quality and cost profile of individual market plans differs materially from group coverage.

The KFF 2024 Employer Health Benefits Survey shows the average annual deductible for covered workers in employer plans at $1,787. Marketplace Silver plan deductibles are substantially higher, averaging above $4,500 nationally in 2024 before cost sharing begins. The fractional professional accustomed to employer-sponsored coverage finds individual market coverage, even at the Gold tier, a meaningful step down in cost-sharing protection.

ICHRA, established in 2020, allows employers to reimburse employees for individual market coverage. The operative word remains employees. A client engaging a fractional executive as a 1099 contractor cannot offer ICHRA because the contractor is not an employee under the arrangement. ICHRA cannot solve this problem. It requires an employment relationship the fractional model is specifically designed to avoid.

Health sharing ministries are not insurance. They do not guarantee claim payment, have eligibility requirements that exclude significant portions of the population, and do not provide essential health benefits as defined by the ACA. Short-term limited-duration plans are underwritten, exclude pre-existing conditions, and carry annual benefit limits. Neither is an adequate substitute for group coverage for a professional-class worker with health complexity typical of someone in their forties, fifties, or sixties.

The Structural Nature of the Exclusion

#

The coverage gap is not closed by improving broker access to the independent workforce. It is not closed by awareness campaigns about marketplace options. It requires either new product categories that do not currently exist or regulatory change that has not occurred.

The ESI system’s foundational assumption is a bilateral employment relationship: one employer, one worker, multi-year duration. The fractional model violates every element of that assumption. Multiple payers. No employer. Duration measured by engagement rather than employment year. The regulatory and product architecture that flows from the ESI assumption has no slot for this worker.

Portable benefits, where coverage attaches to the worker rather than to any single employer and multiple clients contribute to a portable benefit account, are the theoretical solution most frequently discussed in policy circles. The mechanism would allow each client to contribute a fraction of benefit cost proportional to the work the fractional worker performs for them. The administrative architecture for such a system does not currently exist at the federal level. Several states have explored portable benefit frameworks, but none has produced a replicable, carrier-supported product that closes the gap for the high-earning fractional professional.

The population that faces this gap is neither small nor shrinking. The BLS finding that independent contractors account for 7.4% of all workers, concentrated heavily in professional and business services and growing fastest among workers aged 55 and older, defines the scale. The MBO Partners trajectory showing 4.7 million high-earning independents in 2024 growing to 5.6 million in 2025 describes the direction. Each year without a product solution is a year in which more professional-class workers carry individual market coverage that costs more, covers less, and provides narrower network access than the employer group coverage their income could support.

The level funded market intersects this population in a specific way. The fractional professional who forms a corporation, hires even one or two employees, and establishes a single-employer group plan is no longer a fractional worker for coverage purposes. She has become a small employer. This transition, from independent contractor to employer, is the one pathway from individual market coverage to group coverage that current product architecture supports. The level funded market serves her as soon as she crosses the threshold to employer status. It does nothing for her before she does.
