If you own an LLC, a partnership or a sole proprietorship, you probably want to know whether you can run your own health premiums through a Section 125 plan. The short answer is no, but your employees can, and that is where the payroll tax savings come from. This page shows the rule for each entity type and what owners do instead.
What is a Section 125 plan?
A Section 125 plan, also called a cafeteria plan, is a written employer plan that lets employees pay for qualified benefits like health premiums before taxes. Section 125 of the Internal Revenue Code says all participants in a cafeteria plan must be employees (26 U.S.C. 125(d)(1)).
Pre-tax money skips income tax and FICA. FICA is the payroll tax that funds Social Security and Medicare. The IRS sets it at 6.2% plus 1.45% for the employer and the same for the employee (IRS Tax Topic 751, reviewed September 2026).
Can an LLC member, partner or sole proprietor join a Section 125 plan?
No. IRS cafeteria plan training material states that sole proprietors, partners in a partnership, and 2% or greater S corporation shareholders are ineligible to participate in a cafeteria plan (IRS Employee Plans training, Lesson 4). The reason is simple. The tax code treats these owners as self-employed, not as employees.
An LLC is a state legal structure, not a tax class. The IRS says a single-member LLC is disregarded for income tax purposes by default, and a multi-member LLC is classified as a partnership unless it elects otherwise (IRS, Limited Liability Company page). Your tax class decides your answer, not the letters after your company name.
Table: Can the owner join the Section 125 plan?
| Business type | Owner can join? | Employees can join? |
|---|---|---|
| Sole proprietorship | No | Yes, W-2 employees |
| Single-member LLC (default tax treatment) | No | Yes, W-2 employees |
| Multi-member LLC taxed as a partnership | No | Yes, W-2 employees |
| Partnership | No | Yes, W-2 employees |
| LLC that elected S corporation status, owner above 2% | No (IRS Pub. 15-B treats a 2% shareholder like a partner) | Yes, W-2 employees |
| LLC that elected C corporation status, owner on W-2 payroll | Generally yes, subject to testing | Yes, W-2 employees |
The last row has a catch. An owner who is a W-2 employee of a C corporation can usually take part, but owners and other highly paid staff fall under nondiscrimination testing. Ask your CPA to confirm your status before you enroll anyone. Our guide to Section 125 for S-corp shareholders covers the 2% rule in more detail.
Can my employees use a Section 125 plan if I cannot?
Yes. A partnership, sole proprietorship or LLC can sponsor a cafeteria plan for its common-law employees, just not for the owners themselves. Every W-2 employee you choose to cover can make pre-tax elections, and you save the employer share of FICA on each dollar they elect.
The owner exclusion does not weaken the plan for everyone else. It only means your own premiums follow a different route, covered below. Contract workers paid on a 1099 are not employees either. Our post on 1099 contractors and Section 125 explains that rule.
How do LLC members and partners get tax relief on their own premiums?
Owners usually take the self-employed health insurance deduction on their personal return. The IRS Form 7206 instructions say you can claim it as a sole proprietor with a net profit, a partner with self-employment earnings on Schedule K-1, or a more-than-2% S corporation shareholder who received wages from the company.
One limit matters. You cannot take the deduction for any month you were eligible to join an employer-subsidized health plan, even if you did not enroll. That includes a plan offered by your spouse's employer (IRS, Instructions for Form 7206).
This deduction lowers income tax. It does not remove FICA or self-employment tax the way a cafeteria plan does for employees. For a fuller look at owner options, read our guide to health insurance for the self-employed and health insurance for small business owners.
How much can a business with owners and employees save?
Savings depend only on what your employees elect, not on what owners spend. Employer FICA savings equal 7.65% of each employee's pre-tax benefit dollars (IRS Tax Topic 751).
Here is a hypothetical example, not a quote. An LLC taxed as a partnership has two members and six W-2 employees. Each employee elects $1,200 a month in total pre-tax benefits.
Table: Hypothetical monthly math for six enrolled employees
| Line | Per employee | Six employees |
|---|---|---|
| Employer FICA avoided (7.65% of $1,200) | $91.80 | $550.80 |
| Summit administration fee ($35 per enrolled employee per month, paid from the FICA savings) | $35.00 | $210.00 |
| Net employer benefit | $56.80 | $340.80 |
That is about $4,090 a year in this example. Summit Health Benefits estimates net employer savings of about $56 to $101 per enrolled employee per month across typical plans. Your number moves with elections: the $35 fee is covered by FICA savings once an employee elects roughly $457 a month in pre-tax benefits ($35 divided by 7.65%). Our Section 125 savings calculator lets you test your own headcount, and our post on maximizing FICA tax savings explains the math.
Who handles the Section 125 plan for a small LLC or partnership?
Someone has to write the plan, and a payroll deduction code does not count. A Section 125 plan needs a written plan document, and plans must pass nondiscrimination tests (26 U.S.C. 125).
Summit Health Benefits supplies a written plan document, a summary plan description, and nondiscrimination testing support, and its plan documents are reviewed by ERISA attorneys. Summit also checks which people on your roster can join before the plan starts, which matters when owners and family members work in the business. See how to set up a Section 125 plan for the full steps, or start at Get Started with Section 125.
What should owners do before they set up the plan?
Owners should confirm their tax class, list who is a W-2 employee, and decide who gets covered. Four steps cover most small businesses:
- Ask your CPA how your LLC is taxed and whether an S or C corporation election is in place.
- List every W-2 employee, and note any family members on payroll.
- Run the savings estimate using real payroll figures.
- Set the plan up before the plan year starts, and file the written plan document.
