Can An S Corp Owner Participate In A Section 125 Plan?

Quick Answer

No. A more-than-2-percent S corporation shareholder is not treated as an employee for Section 125 purposes and may not participate in a cafeteria plan. Sole proprietors, partners in a partnership and corporate directors acting solely as directors are excluded on the same basis, and family attribution rules apply to the 2 percent shareholder test.

Only employees may participate in a cafeteria plan, and federal law does not treat several common categories of business owner as employees for this purpose. A shareholder owning more than two percent of an S corporation is excluded, as are sole proprietors, partners in a partnership and corporate directors acting only as directors. Family attribution extends the exclusion to a spouse, child, parent or grandparent of a more-than-two-percent shareholder. The practical consequence is blunt: a single-owner business whose only person on payroll is that owner has essentially no employer payroll tax to save through a premium only plan. What the owner uses instead is the self-employed health insurance deduction, which reduces income tax but produces no payroll tax saving at all.

This is the question that should be asked first and usually gets asked last, normally after someone has already been sold a plan.

Section 125 plans are for employees. Federal law does not treat several very common categories of business owner as employees for this purpose, and in Nevada, where S corporations and single-member structures are everywhere, that matters.

Who is excluded from participating?

Only employees may participate in a cafeteria plan, and four categories of person are not employees for Section 125 purposes.

More-than-2-percent S corporation shareholders. Sole proprietors. Partners in a partnership. And corporate directors acting solely as directors.

IRS Publication 15-B[1], the employer’s tax guide to fringe benefits, states the S corporation rule directly: “Don’t treat a 2% shareholder of an S corporation as an employee of the corporation for this purpose.” The publication instructs employers to treat such a shareholder as they would a partner in a partnership for fringe benefit purposes.

Self-employed individuals generally are excluded on the same footing. The logic is consistent rather than arbitrary: a cafeteria plan works by converting wages into a nontaxable benefit, and someone who does not receive wages in the relevant sense has nothing to convert.

Family attribution catches people off guard

The exclusion does not stop at the shareholder. Attribution rules apply to the 2 percent test, so a spouse, child, parent or grandparent of a more-than-2-percent shareholder is treated as a more-than-2-percent shareholder too.

That result is genuinely counterintuitive. An owner’s daughter who works 40 hours a week as a real W-2 employee, doing real work, at market pay, is still excluded from the cafeteria plan because of who her parent is. Family-run businesses across the valley are exactly the profile where this gets missed, and it gets missed for years because nothing on a paystub looks wrong.

What does that mean for a one-owner business?

That a premium only plan may be worth nothing at all. This is the honest answer that rarely accompanies the sales pitch.

The employer payroll tax reduction is generated by employee salary reductions. A single-owner S corporation with no non-owner employees on payroll has no eligible participant, therefore no salary reductions, therefore no reduction in employer FICA or FUTA. The plan document would sit in a drawer describing a benefit nobody can use.

Anyone recommending a POP into that situation should be asked who they expect to participate. If the answer is the owner, the recommendation is wrong.

The plan becomes worthwhile the moment there are non-owner W-2 employees paying premiums through payroll, because their salary reductions are what produce the employer saving. The mechanism and the rates are in do pre-tax premiums lower employer payroll taxes.

What does an excluded owner use instead?

A different provision with a different benefit, and the difference is the part worth understanding precisely.

An owner excluded from the cafeteria plan generally takes the self-employed health insurance deduction under IRC section 162(l). It is an above-the-line income tax deduction, which is genuinely valuable, but it produces no FICA, SECA or FUTA saving whatsoever.

So the same premium, in the same household, gets different tax mechanics depending on how the person is classified. A W-2 employee running premiums through a Section 125 plan saves income tax and payroll tax, and generates an employer payroll tax saving at the same time. An excluded owner saves income tax only.

That distinction is the reason self-employed Nevadans need different advice rather than a scaled-down version of employer advice. The self-employed side is covered in can self-employed Nevadans deduct health insurance premiums and are health premiums deductible for 1099 contractors, and the structural options in health insurance options for the self-employed in Nevada.

How the 2 percent threshold is measured

Ownership rather than payroll, and at any point during the year rather than on a single date. A shareholder who holds more than 2 percent of the outstanding stock, or stock carrying more than 2 percent of the voting power, on any day of the tax year is caught.

That has a consequence for businesses whose ownership changed mid-year. A person who sold down below the threshold in March was still a more-than-2-percent shareholder for that tax year, and someone who bought in during November becomes one for the whole year. Plan participation decisions made on a January ownership snapshot can therefore be wrong by December.

The arithmetic on the other side of the question, what the employer actually saves when eligible employees do participate, runs on the employer payroll tax rates and the annual Social Security wage base published in IRS Publication 15[2]. For a business with a handful of non-owner employees the saving is modest but real, and for a business with none it is zero.

What should be checked in an existing plan?

Who is coded as a participant. An excluded owner, a partner, or an owner’s spouse sitting in the participant list is a defect regardless of how long it has been that way.

That matters because the correction is not cosmetic. Amounts treated as pre-tax for someone who was never eligible were mischaracterized, which reaches the individual’s return and the employer’s payroll reporting. Finding it during a review is considerably better than finding it during an examination.

Two related checks belong in the same pass: whether a valid plan document exists at all, covered in does a Section 125 plan need a written document, and what the plan is actually offering, in what is a Section 125 premium only plan. The whole mechanism sits in how a Section 125 plan cuts employer payroll tax.

We are insurance nerds, not tax professionals. Ownership percentages, attribution, and whether a specific person may participate are questions for a licensed tax professional who can see the actual ownership structure.

Frequently Asked Questions

Why are S corporation owners excluded?

Because only employees may participate in a cafeteria plan, and a more-than-2-percent S corporation shareholder is not treated as an employee for Section 125 purposes. IRS Publication 15-B instructs employers not to treat a 2 percent shareholder as an employee for fringe benefit purposes and to treat that person as a partner in a partnership instead.

Which other owners are excluded?

Sole proprietors, partners in a partnership, and corporate directors acting solely as directors. Self-employed individuals generally are not treated as employees for Section 125 purposes, so they may not participate in a cafeteria plan.

Does the exclusion reach family members?

Yes. Attribution rules apply to the 2 percent shareholder test, so a spouse, child, parent or grandparent of a more-than-2-percent shareholder is treated as a more-than-2-percent shareholder and is likewise excluded, even if that relative is a genuine W-2 employee.

What does an excluded owner use instead?

Generally the self-employed health insurance deduction under IRC section 162(l). It is an above-the-line income tax deduction, and unlike a Section 125 salary reduction it produces no FICA, SECA or FUTA saving. Whether it applies and how much is deductible is a question for a licensed tax professional.

Can a plan still be worthwhile if the owner is excluded?

Yes, if there are non-owner W-2 employees paying premiums through payroll, because the employer payroll tax reduction is generated by their salary reductions. A business whose only person on payroll is an excluded owner has essentially nothing to save this way.
