Your benefits package looks broad, enrollment is healthy, and leadership assumes the compliance work is under control. Then an advisor asks whether the self-insured medical plan and the company's pre-tax accounts were tested separately. The room goes quiet. A plan can satisfy IRC Section 105(h) while an attached cafeteria arrangement under IRC Section 125 still has a problem.
That distinction creates one of the most avoidable risks in employee benefits. Health plan nondiscrimination testing isn't a single fairness review. It's a set of technical tests that evaluate eligibility, benefits, contributions, employee classifications, and key employee concentration. The IRS uses defined thresholds, and a failure can cause benefits that were intended to be tax-free to become taxable for highly compensated individuals, including founders, officers, and other senior employees.

The Hidden Compliance Trap in Employee Benefits
A growing company's HR team may start with a reasonable assumption. Most employees can enroll in the medical plan, the company contributes toward coverage, and the benefits guide doesn't contain any obvious executive-only language. The team concludes that the organization's health plan nondiscrimination testing is effectively complete.
That conclusion is unsafe.
The medical plan may be subject to Section 105(h), while the pre-tax premium arrangement, flexible spending account, or related cafeteria benefits may be subject to Section 125. These rules don't ask identical questions, use identical tests, or produce identical outcomes. Passing the medical plan test doesn't automatically make an FSA, HSA arrangement, or other tax-advantaged component compliant. Thomson Reuters' explanation of nondiscrimination rules for self-insured plans addresses this separation, which remains under-explained in many benefits discussions.
The executive enrollment surprise
Consider a company where employees across departments may enroll in a self-insured medical plan, but highly compensated employees are much more likely to elect coverage. The plan's written eligibility language might appear neutral. Actual participation, however, can still affect the eligibility analysis.
Now add a health FSA. Executives may make larger elections, while many hourly employees choose not to participate because they have limited disposable income or prefer different benefits. The medical plan could pass its applicable tests while the cafeteria plan's contribution or key employee analysis produces a different result.
That outcome isn't evidence that the company intended to favor executives. It shows why compliance depends on how a plan operates, not just how the summary plan description reads.
Practical rule: Treat every tax-advantaged benefit as its own compliance workstream before you combine the results.
The consequences are more serious than a spreadsheet correction. Under the Section 105(h) framework, failure of either the eligibility or benefits test can cause some benefits paid to highly compensated individuals to become taxable, as described in this overview of Section 105(h) nondiscrimination testing. For leaders already reviewing workplace discrimination exposure, Lerner & Weiss APC on FEHA compliance offers useful context on how broader employment practices can create legal risk, even though FEHA compliance and federal benefits testing are separate issues.
The operational lesson is direct. Don't ask whether your benefits package feels fair. Ask which tax code section applies to each component, which employees count in each test, and whether the census data supports the answer.
Decoding IRC Section 105(h) for Self-Insured Plans
A company can offer identical medical plan terms to every employee and still fail IRC Section 105(h). The risk often sits in eligibility records, plan administration, or a reimbursement feature available only to executives. Section 105(h) applies to self-insured medical reimbursement plans and requires two separate reviews: who may participate and whether the benefits favor highly compensated individuals.
Passing one review does not establish compliance with the other. A plan may admit a sufficiently broad employee group while giving a select group richer reimbursements, or offer uniform benefits while excluding too much of the workforce.
The eligibility test
One route requires coverage for at least 70% of all non-excludable employees. Another can apply when at least 70% of all employees are eligible and at least 80% of those eligible employees benefit. These thresholds and the broader classification alternative are described in guidance on Section 105(h) eligibility testing.
A plan may also use a nondiscriminatory classification based on bona fide business criteria, including job category, salaried or hourly status, or geography. The classification cannot function as a disguised way to cover owners and executives while excluding the broader workforce. OneDigital's discussion of nondiscriminatory employee classifications explains how these criteria fit into the analysis.
Eligibility testing depends on a clean employee population, documented exclusions, and reliable enrollment records. Payroll, human resources, ownership, and benefits systems must agree. If enrollment is concentrated among highly compensated employees, identical deductibles and covered services will not cure an eligibility problem.
The benefits test
The benefits test examines both design and operation. A plan must not favor highly compensated individuals through richer coverage, better reimbursement terms, or selective features. For example, an executive-only reimbursement top-up can create a benefits-test problem even when the underlying medical plan is available to the broader workforce. Technical guidance on self-insured medical reimbursement plans explains why eligibility and benefits require separate evaluation.
The highly compensated individual definition includes the top 25% of non-excludable employees, the five highest-paid officers, and more-than-10% shareholders. These categories may overlap, and changes in ownership or officer records can alter the testing population.
Review participation and plan design together. A provider familiar with self-funded insurance administration and resources can help, but leadership must supply a census reconciled against payroll, ownership records, officer data, and plan enrollment. Clean data is the control that supports both accurate testing and defensible decisions.
Navigating Section 125 Cafeteria Plan Requirements
Section 125 testing follows a different track. Cafeteria plans commonly support pre-tax premium arrangements, health FSAs, and dependent care accounts. The plan's compliance analysis doesn't disappear because the underlying medical coverage passed Section 105(h).
A cafeteria plan must pass three separate annual tests:
- Eligibility test, which examines whether the plan is available on a nondiscriminatory basis.
- Contributions and benefits test, which evaluates whether contributions and benefits favor highly compensated employees.
- Key employee concentration test, under which nontaxable benefits provided to key employees can't exceed 25% of total nontaxable benefits under the plan. The threshold is described in cafeteria plan compliance guidance.
The distinction becomes clearer when the frameworks sit side by side.
| Feature | IRC Section 105(h) | IRC Section 125 |
|---|---|---|
| Primary application | Self-insured medical reimbursement plans | Cafeteria plans and pre-tax benefit arrangements |
| Core tests | Eligibility and benefits | Eligibility, contributions and benefits, and key employee concentration |
| Key participation issue | Whether access favors highly compensated individuals | Whether eligibility and elections operate on a nondiscriminatory basis |
| Concentration threshold | Uses the Section 105(h) eligibility and benefits framework | Nontaxable benefits to key employees can't exceed 25% of total nontaxable benefits |
| Common operational inputs | Enrollment, employee classifications, plan design, ownership and officer status | Payroll elections, employer contributions, compensation, ownership, officer status, and participation |
Why bundled benefits cause trouble
Companies often administer medical coverage alongside HSAs, HRAs, FSAs, and premium-only arrangements. Employees experience these offerings as one benefits package. The tax code doesn't necessarily evaluate them as one package.
An HSA arrangement may have its own eligibility considerations. An FSA may be part of a Section 125 cafeteria plan. An HRA may sit within a self-insured medical structure. The compliance answer depends on the legal design and the way the employer funds and administers each benefit.
Passing the medical plan test doesn't certify every tax-advantaged account attached to the benefits program.
Payroll data becomes especially important here. An incorrect pre-tax election, missing employer contribution, or incomplete participation file can distort the contributions and benefits analysis. Use a dedicated process for each Section 125 component, and document which test applies before asking whether the result is a pass.
For teams administering FSAs, Benely's flexible spending account administration resources can help organize the account workflow. The broader compliance decision still belongs with qualified benefits counsel or an experienced testing advisor.
Avoiding Data Traps and Classification Errors
A passing test is only as reliable as the employee census behind it. A formula can run correctly while producing the wrong result if the file includes the wrong employees, uses inaccurate compensation, or misses an ownership relationship. That creates a dangerous operational problem: IRC §105(h) medical plan testing and IRC §125 cafeteria plan testing rely on overlapping data, but they do not answer the same compliance question. Passing one does not establish compliance with the other.
Three classification errors require immediate review:
- Officer status: An outdated officer list can place the wrong people in the highly compensated individual population or exclude a relevant officer.
- Ownership attribution: More-than-10% shareholder status under Section 105(h) requires accurate ownership records. Related ownership details must be verified, not assumed.
- Compensation history: Prior-year compensation and employee status can affect HCI determinations under cafeteria plan rules. A current payroll export may not provide enough history.
A false pass gives leadership unwarranted confidence. A false failure can create unnecessary corrections, employee communications, and tax reporting work. Clean census data is the control that supports both tests.
Build a controlled census process
Assign responsibility for every data field. HR should maintain employment status and job classification. Payroll should validate compensation and pre-tax elections. Finance or legal should confirm ownership and officer information. The benefits administrator should reconcile eligibility with actual participation.
Preserve an audit trail that records:
- Population rules: Which employees were included or excluded, and why.
- Status history: When an employee became an officer, owner, or another relevant classification.
- Plan records: Eligibility terms, enrollment files, employer contributions, and election data.
- Reconciliation notes: How payroll totals were matched to the administrator's records.
For teams administering FSAs, Benely's flexible spending account administration resources can help organize account workflows. The employer still needs a separate testing process for each Section 125 component and the self-insured medical plan.
The Affordable Care Act also broadened the policy discussion around nondiscrimination. Its attempted extension of nondiscrimination rules to insured group health plans was reflected in Department of Labor guidance, although implementation was not immediately operationalized. That history reinforces the need to identify the rule and data set that apply to each benefit.
Spreadsheets can work, but only with assigned ownership, documented reconciliations, and preserved supporting evidence.
Establishing a Proactive Testing Timeline
A company can pass its Section 105(h) medical plan test and still fail its Section 125 cafeteria plan test. The reverse is also possible. Treating one result as proof of overall compliance creates a serious operational risk, so schedule separate testing for each applicable arrangement and use one clean, reconciled census as the foundation for both.
Complete health plan nondiscrimination testing by the last day of the plan year. Run a mid-year pre-test early enough to correct an imbalance before year-end, following this compliance timeline for nondiscrimination testing.
Early plan-year review
Map the legal structure of every benefit. Identify the self-insured medical plan, cafeteria plan, premium-only arrangement, FSA, HRA, HSA-related design, and other tax-advantaged components. Confirm each arrangement's eligibility rules, testing population, and treatment of highly compensated and key employees. Reconcile current job categories, locations, employment statuses, and ownership records before testing begins.
Data preparation
Build the census from employee status, compensation history, payroll elections, employer contributions, enrollment records, officer lists, ownership information, and eligibility dates. Assign one owner to reconcile employee identifiers and dates across payroll, HR, and benefits records. Clean data matters more than a polished spreadsheet. If the census is wrong, neither the Section 105(h) result nor the Section 125 result is dependable.
Mid-year diagnostic
Run separate preliminary analyses for the medical plan and cafeteria plan. Review participation, employer funding, pre-tax elections, and patterns that favor highly compensated or key employees. If either analysis shows risk, correct the underlying classification or administration issue first. Then evaluate enrollment communications, contribution design, and other permitted corrections with qualified advice.
Year-end test and correction
Complete the applicable Section 105(h) and Section 125 tests by the plan-year deadline. Preserve the final census, outputs, assumptions, source reports, classification rationale, and correction decisions. For classifications based on geography or job category, retain evidence of the business reason and how the rule operates.
A quarterly review keeps live participation aligned with the testing file. Enrollment changes, payroll deductions, and employer funding can shift during the year. The final record should show both conclusions and the reconciliations that support them.
Automating Compliance with Modern Benefits Partners
Manual spreadsheets create too many handoff points. HR updates an employee's status, payroll maintains compensation and deductions, a benefits administrator holds enrollment data, and finance tracks ownership. If those systems don't agree, the testing file becomes a reconstruction project.
A modern benefits platform should create a controlled source for the information used in testing. Look for connected payroll, onboarding, enrollment, and compliance workflows. The practical objective isn't to replace legal judgment. It's to reduce duplicate entry, surface missing classifications, and preserve a consistent record of who was eligible, who enrolled, and what the employer contributed.
Benely's employee benefits management platform brings benefits administration, employee data, enrollment activity, and compliance tools into a centralized workflow. Its platform supports comparison of more than 4,000 health plans from carriers including Aetna, Kaiser, Anthem, Blue Shield, and UnitedHealthcare, while also helping teams set budgets, automate enrollments, and track open enrollment progress. Those capabilities address the operational side of testing by keeping plan participation and employee records closer to the administration process.
Automation still needs governance. Configure approval rules, require documented ownership updates, and schedule reconciliations between payroll and the benefits system. A platform can flag inconsistent records, but leadership should decide how to correct an officer classification or interpret a complex plan design.
Certified HR specialists can also help benchmark a benefits program, review administration practices, and evaluate PEO options when a co-employment model fits the company's needs. That support is useful when a growing organization lacks in-house benefits counsel, but the employer should retain clear responsibility for final plan decisions and tax reporting.
A connected process changes the rhythm of compliance. Instead of assembling a crisis spreadsheet at year-end, HR maintains the underlying records throughout the benefits lifecycle.
Use the video as an orientation point for the technology workflow, then ask your advisor to map each data field to the specific Section 105(h) or Section 125 test it supports.
Your Action Plan for Nondiscrimination Success
Leadership doesn't need another generic compliance reminder. It needs a repeatable operating model with a clear owner, reliable data, and enough time to correct problems.
Start with this checklist:
- Separate the legal tracks: Test self-insured medical benefits under Section 105(h), and test cafeteria arrangements under Section 125. Don't treat a medical plan pass as a blanket approval for every related account.
- Define the testing population: Confirm non-excludable employees, highly compensated individuals, key employees, officers, shareholders, and other relevant classifications before running formulas.
- Reconcile the census: Match HR records, payroll, ownership information, compensation history, elections, employer contributions, and enrollment data.
- Run a pre-test: Use a mid-year diagnostic to identify participation or contribution patterns that can still be corrected.
- Review plan design: Compare eligibility terms, employer contributions, reimbursement levels, and access to benefits across employee groups.
- Document classifications: If eligibility relies on geography, job category, salaried or hourly status, or another business criterion, record the rationale and operating evidence.
- Preserve the file: Keep source reports, assumptions, test results, correction decisions, and approval records together.
- Escalate exceptions: Send ownership questions, executive classifications, unusual plan designs, and potential failures to qualified benefits counsel or a specialist.
Competitive benefits help employers recruit and retain people, but the program has to work for the whole workforce and withstand technical review. The strongest approach pairs Section 105(h) testing, Section 125 testing, disciplined data governance, and an administration system that keeps records current.
Don't wait for a taxable-benefit notice or an executive escalation. Put the testing calendar in place, assign data owners, and review your current process before the next plan-year deadline.
