Introduction
If you’ve been researching Section 125 indemnity plans — or talking to brokers about them — you may
have heard two different types of carrier structures come up: fully insured and level-funded. On the
surface, both offer the same promise: pre-tax benefits that reduce FICA taxes for employees and
employers.
But the way they’re structured is fundamentally different. And if you’ve done any deeper research, you
may have also come across the fact that level-funded Section 125 arrangements have attracted
scrutiny from benefits professionals, compliance attorneys, and even the IRS in certain contexts.
We’re going to be straight with you about all of it. Not because we want to alarm you, but because
understanding the difference is exactly the kind of thing that separates a business owner who makes
informed benefits decisions from one who gets surprised down the road.
A Note Before We Start
This article discusses compliance considerations and IRS scrutiny in the context of level-funded
Section 125 arrangements. Our goal is to give you a balanced, factual overview — not to discourage
you from Section 125 plans, which remain a legitimate and widely used tax strategy when structured
correctly. The key phrase is ‘when structured correctly,’ and that’s exactly what we’ll address here.
First: A Quick Recap of How Section 125 Works
A Section 125 indemnity plan works by delivering supplemental insurance benefits to employees
through a pre-tax payroll mechanism. The employee’s taxable income is reduced by the value of the
benefit, which means less FICA tax for the employee — and less employer-side FICA as well.
The underlying insurance benefit — typically hospital indemnity, accident, or critical illness coverage —
is provided by an insurance carrier. How that carrier funds and structures its insurance product is
where fully insured and level-funded models diverge.
Fully Insured Section 125 Plans
In a fully insured Section 125 arrangement, the insurance carrier assumes all financial risk. The carrier
underwrites the benefit product using its own capital, collects premiums, and pays claims from its own
reserves — the same way a standard insurance product works.
How It Works
Employees’ pre-tax payroll deductions go to the carrier as premium payments. The carrier manages
the risk pool across all of its policyholders. Individual employers don’t bear claims risk — the carrier
does. The plan is structured, regulated, and backed like a traditional insurance product.
IRS and Regulatory Standing
Fully insured Section 125 indemnity plans have a clean, well-established compliance profile. The
insurance products underlying these plans are state-regulated, actuarially sound, and structured in a
way that has been clearly validated under Section 125 of the tax code. There is a long track record of
IRS acceptance when these plans are properly documented and administered.
Tradeoffs
Fully insured plans don’t offer surplus refunds — the carrier keeps any difference between premiums
collected and claims paid. Pricing is set by the carrier’s actuarial models. Employers don’t see claims
data for the underlying benefit product in the same way they might with a level-funded health plan.
Level-Funded Section 125 Plans — A Different Structure
In a level-funded Section 125 arrangement, the structure is more complex. Rather than a traditional
carrier assuming all risk on a fully underwritten basis, level-funded plans typically involve a combination
of stop-loss insurance, a claims fund, and administrative services — with the financial risk shared or
partially retained differently than in a fully insured model.
How It Works
Employer contributions fund a claims account. A stop-loss policy caps exposure if claims exceed
projections. An administrator manages the plan mechanics and compliance structure. At year-end, if
claims came in lower than projected, there may be a surplus returned to the employer or credited to
future costs.
The Appeal
Level-funded structures can offer cost advantages and the possibility of financial upside if claims run
low. For health insurance, level-funded arrangements are well-established and widely accepted. The
concept of shared risk and potential surplus refunds is genuinely appealing, and many businesses
benefit from this model in health coverage.
Where the Scrutiny Comes From
Here’s where we get direct with you: some level-funded Section 125 indemnity arrangements have
drawn compliance scrutiny — not because the concept is inherently flawed, but because certain
implementations have been structured in ways that push the boundaries of what the IRS considers
legitimate pre-tax treatment.
The Core Compliance Concern
The IRS requires that Section 125 benefits represent genuine risk transfer — meaning employees
are receiving a real insurance benefit in exchange for their pre-tax contributions, not simply moving
their own money around in a way that artificially reduces taxable income without a substantive
benefit attached.
Some level-funded Section 125 arrangements have been structured in ways where the ‘insurance’
component is thin — where the claims fund is effectively just employees’ own money being cycled
back to them, with minimal genuine risk transfer. In these cases, the IRS has taken the position that
the pre-tax treatment is not valid, which can expose employers to back taxes, penalties, and interest.
The Important Distinction
It is critical to understand that the concern is not about level-funded plans as a category — it is about
specific implementations that lack genuine risk transfer. A well-structured level-funded Section 125
arrangement, backed by legitimate stop-loss insurance, actuarially sound claims projections, and a real
insurance benefit, can be fully compliant.
The problem arises when carriers or promoters prioritize the appearance of tax savings over substance
— offering arrangements that look like Section 125 plans on the surface but don’t meet the underlying
requirements. These are sometimes marketed aggressively because the projected savings look
attractive, and employers without independent guidance may not know how to tell the difference.

How to Evaluate a Level-Funded Section 125 Proposal
If a carrier or broker presents you with a level-funded Section 125 arrangement and it looks attractive,
the right move is not automatic rejection — it’s careful evaluation. Here’s what to ask:
Is there genuine risk transfer?
Can the carrier clearly demonstrate that employees are receiving a real insurance benefit —
one where a third party (the carrier) bears meaningful financial risk? If the answer involves
employees essentially just receiving their own money back with a different label, that’s a red
flag.
Is the stop-loss insurance real and adequate?
Level-funded arrangements should be backed by actuarially sound stop-loss coverage that
genuinely protects the employer from excess claims. Ask for the stop-loss policy details and
attachment points. Thin or nominal stop-loss is a warning sign.
Has independent legal or compliance review been done?
Any legitimate level-funded Section 125 carrier should be able to point to independent ERISA
counsel or tax counsel opinions supporting the plan’s structure. If the compliance support is all
in-house, ask more questions.
What is the carrier’s track record with IRS audits?
Has the plan structure been tested? Does the carrier have documented cases where plans
withstood IRS scrutiny? Legitimate carriers in this space can speak to this.
What are the plan documents like?
Robust, carefully drafted plan documents are a sign of a carrier that takes compliance seriously.
Thin documents with vague language around the insurance structure are a warning sign.
Our Position at Pioneer Benefits Partners
We work with both fully insured and level-funded Section 125 carriers — because the right answer for
any given business depends on their specific situation, workforce, and risk tolerance.
What we don’t do is recommend a level-funded Section 125 arrangement without being confident in its
compliance foundation. We have evaluated enough carriers in this space to know which ones have
invested in genuine, substantive plan structures and which ones are primarily selling a tax savings
number with a thin compliance backbone behind it.
When we present a level-funded option, it’s because we’ve done the diligence. When we recommend a
fully insured option instead, it’s because the compliance profile and reliability outweigh the potential
upside of the level-funded alternative for that client’s situation.
Either way, you’ll know exactly what you’re getting, why we’re recommending it, and what the risk
profile looks like. That’s the only way we’re comfortable making a recommendation.
The Bottom Line
Section 125 indemnity plans — both fully insured and properly structured level-funded arrangements
— are legitimate, valuable strategies for reducing FICA taxes for employees and employers.
The risk is not in the strategy itself. The risk is in working with carriers or promoters who prioritize the
appearance of savings over the substance of a compliant plan.
An independent broker who knows the space, has evaluated the carriers, and can explain the
compliance foundation of whatever they’re recommending is your best protection against that risk.
That’s exactly what we do.
