Who Is Not Eligible for Section 125 Plan: The Complete Exclusion List

Section 125 excludes business owners from participating as employees in the cafeteria plan they sponsor. The exclusion applies to more-than-2% S corporation shareholders and their family members, partners in a partnership, sole proprietors, and members of LLCs taxed as partnerships. They can sponsor the plan and offer it to employees, but they cannot elect their own benefits on a pre-tax basis through it. Here is the complete list, the tax code behind each exclusion, and what those owners can still do.

The Four Groups Who Cannot Participate

More-Than-2% S Corporation Shareholders

If you own more than 2% of an S corporation's stock at any point during the year, Section 125 does not treat you as an employee for cafeteria plan purposes. You cannot pay health insurance premiums, contribute to an FSA, or elect any other benefit through the plan on a pre-tax basis.

The rule appears in 26 USC §1372(b), which defines "employee" for S corporation fringe benefit purposes. More-than-2% shareholders are specifically carved out. IRS Publication 15-B repeats the rule: health insurance premiums and other fringe benefits are taxable compensation to you, not excludable benefits.

Family attribution makes the exclusion broader than it looks. Under Section 318, stock owned by your spouse, children, parents, and grandparents is attributed to you when testing the 2% threshold. If your spouse owns 1.5% and you own 1%, you are both treated as more-than-2% shareholders and both excluded.

Partners in a Partnership

Partners cannot participate in a Section 125 plan sponsored by the partnership. The tax code does not treat partners as employees of the partnership. Instead, they receive a distributive share of partnership income and are taxed on guaranteed payments, but they have no wages and no W-2.

Without wages, there is nothing to reduce through a Section 125 election. The pre-tax benefit only works when you are paying income tax and FICA on W-2 wages that can be redirected before tax. Partners pay self-employment tax on their share of income, and Section 125 does not touch that.

This applies whether the partnership is a general partnership, a limited partnership, or an LLP. If you are classified as a partner for tax purposes, you are excluded.

LLC Members Taxed as Partnerships

If your LLC is taxed as a partnership (the default for multi-member LLCs), the members are treated the same as partners. They are not employees, they receive a distributive share or guaranteed payments, and they cannot participate in the Section 125 plan.

If your LLC elected S corporation taxation, the more-than-2% shareholder rule above applies instead. If it elected C corporation taxation, you may be an employee, and the Section 125 exclusion does not apply unless you are a more-than-2% owner under a different test. Most small LLCs are taxed as partnerships or S corps, so one of these exclusions usually applies.

Sole Proprietors

A sole proprietor is the business. You cannot be your own employee. You have no wages, no W-2, and no payroll to reduce through a cafeteria plan. Section 125 requires an employment relationship, and you do not have one with yourself.

If you have employees, you can sponsor a Section 125 plan and offer it to them. You simply cannot participate in it yourself.

What Excluded Owners Can Still Do

The exclusion blocks you from the pre-tax election, but it does not block the underlying benefits or all tax relief.

Sponsor the Plan for Your Employees

Every excluded group listed above can adopt a Section 125 plan and offer it to employees. The exclusion applies only to your own participation. If you are a more-than-2% S corp shareholder with ten employees, those ten employees can pay their health insurance premiums pre-tax, contribute to FSAs, and access every benefit a compliant Section 125 plan allows. You just cannot do it yourself.

The nondiscrimination rules under Section 125 do not count you as a highly compensated employee if you cannot participate. The testing pool includes only those eligible to participate.

Deduct Health Insurance Premiums Elsewhere

More-than-2% S corporation shareholders, partners, and sole proprietors can deduct health insurance premiums as an above-the-line deduction on Form 1040, line 17 (Self-Employed Health Insurance Deduction). This deduction reduces your income tax but does not reduce self-employment tax or FICA.

The deduction is limited to your net earnings from the business and cannot exceed the amount of the premium. If the S corporation pays the premium and reports it as wages on your W-2, you can take the deduction on your 1040, but the premium is still subject to income tax and is included in your W-2 box 1.

This is not as favorable as a Section 125 election for an employee, because the employee avoids both income tax and the FICA withholding. You avoid income tax but not the employment tax equivalent. Still, it is better than paying the premium with after-tax dollars and claiming no deduction.

Contribute to an HSA Directly

If you have a qualifying high-deductible health plan, you can contribute to an HSA outside of Section 125. The contribution is deductible on your 1040 (line 13 for 2023 and forward), whether you are self-employed or a more-than-2% S corp shareholder. The contribution reduces your income tax, and the account grows tax-free.

Employees can contribute to an HSA through a Section 125 cafeteria plan, which also avoids FICA. Your direct contribution does not avoid the employment tax equivalent, but you still get the income tax deduction and the tax-free growth.

Why the Exclusion Exists

The exclusion is not arbitrary. Congress wrote Section 125 to let employees choose between taxable and nontaxable benefits before they receive compensation. The idea is that the employee redirects part of their wages to pay for benefits before tax touches the wages.

Owners in the excluded categories do not receive wages in the traditional sense. Partners and sole proprietors have no wages at all. More-than-2% S corp shareholders have wages, but they also control the corporation and can set their own compensation. The legislative history and IRS guidance reflect concern that owners could manipulate the benefit to avoid tax in ways employees cannot.

The family attribution rule for S corporation shareholders exists for the same reason. Without it, a husband and wife could each own 2% and avoid the exclusion, even though they effectively control the company together. Attribution treats them as a single unit and applies the exclusion.

None of this means the exclusion is popular. Many owners resent being locked out of a benefit they offer to employees. The tax code draws the line here anyway.

What Happens If You Participate Anyway

If an excluded owner participates in a Section 125 plan, the IRS treats the arrangement as noncompliant. The benefits are taxable to the owner, and depending on how the error is structured, the plan may fail nondiscrimination testing or lose its cafeteria plan status entirely.

If the plan fails, every participant's elections may become taxable. The company must correct the W-2s, and employees who thought they paid premiums pre-tax may owe tax and penalties. The setup steps for a Section 125 plan include identifying who is eligible before you adopt the document. Getting this wrong is not a paperwork error. It is a plan failure.

Most third-party administrators and payroll providers will refuse to process elections for more-than-2% shareholders, partners, or sole proprietors if you disclose the ownership structure. If you do not disclose it, the error will surface in an audit or when the provider reviews the Form 5500 (if your plan must file one).

What About C Corporation Owners?

C corporation shareholders are employees if they work for the corporation and receive wages. A C corp owner can participate in the company's Section 125 plan unless a different exclusion applies (for example, if the plan defines eligibility in a way that excludes them).

The more-than-2% rule applies only to S corporations. If you are the sole shareholder of a C corporation and you receive a W-2 from the corporation, you can participate in the cafeteria plan as an employee. The corporation pays its own income tax, and your wages are subject to income tax and FICA like any other employee. Section 125 lets you pay your premiums before both.

The tradeoff is double taxation on corporate profits. That tradeoff is usually worse than the benefit of cafeteria plan eligibility, which is why most small business owners choose S corporation or partnership taxation. You can review the pros and cons of Section 125 plans to weigh the benefit against the other costs of offering a plan.

FAQ

Can a partner participate if they also receive W-2 wages from the partnership?

No. If a partnership issues a W-2 to a partner, the IRS typically recharacterizes those payments as guaranteed payments or a distributive share. Partners are not employees, even if the partnership reports some compensation on a W-2. Do not structure it this way. The income is still self-employment income, and participating in Section 125 based on a W-2 will fail in an audit.

Does the 2% shareholder rule apply if I own exactly 2%?

No. The exclusion applies only if you own more than 2%. If you own exactly 2%, you are not excluded under this rule. Family attribution still applies, so if your spouse owns any amount, the combined total determines your status. Exactly 2% total across you and attributed family members keeps you eligible.

Can a sole proprietor with no employees adopt a Section 125 plan for themselves?

No. If you have no employees, there is no one eligible to participate, and the plan has no purpose. You cannot adopt a cafeteria plan covering only yourself. If you later hire employees, you can adopt the plan at that time and offer it to them.

What if I am a 1% shareholder but my spouse owns 1.5%?

You are both treated as more-than-2% shareholders. Family attribution combines your ownership with your spouse's ownership, and any stock either of you owns counts toward both of your totals. You are both excluded from participating in the cafeteria plan.

What to Do Next

If you are an excluded owner, review what to look for when someone implements a Section 125 plan for your employees. You cannot participate, but you can still offer the benefit and structure it correctly. Confirm your entity type, ownership percentage, and family attribution before you adopt the plan document.

If you are eligible and want to understand how the plan works, start with what a Section 125 plan is and the requirements that must be met. The exclusion does not make the plan less useful for employees. It just means you are not one of them.
