If you’re a small business owner offering health insurance to your employees, there’s a good chance you’re leaving money on the table every year. A Section 125 cafeteria plan — named after the IRS code section that authorizes it — is one of the most powerful and underutilized tax-saving tools available to small businesses. It allows both employers and employees to pay for certain benefits with pre-tax dollars, reducing payroll taxes for the business and income taxes for employees. This guide explains how cafeteria plans work, what they cover, and why every small business with group benefits should have one.
What Is a Section 125 Cafeteria Plan?
A Section 125 cafeteria plan is a written employer benefit plan that allows employees to choose between receiving cash (taxable wages) or certain non-taxable benefits. By electing benefits under a Section 125 plan, employees reduce their taxable income — meaning they pay less in federal income tax, Social Security tax, and Medicare tax. Employers also save because they don’t pay payroll taxes (FICA) on the amounts employees contribute to benefits through the plan.
The term “cafeteria plan” comes from the analogy of a cafeteria where you can choose from a menu of options — employees select the benefits they want from a menu of qualified options rather than receiving a one-size-fits-all package.
According to the Society for Human Resource Management (SHRM), implementing a Section 125 plan can save employers approximately 7.65% in FICA taxes on every dollar employees redirect from wages to benefits. For a business with 10 employees each contributing $200/month to health insurance, that’s nearly $1,840 per year in employer payroll tax savings — at virtually no cost to implement.
Types of Benefits That Qualify Under Section 125
Not all benefits qualify for Section 125 treatment. The IRS has specific rules about what can be included in a cafeteria plan. The most common qualified benefits include:
- Group health insurance premiums — The most common use. Employee contributions to employer-sponsored health, dental, and vision insurance can be made pre-tax through a Section 125 plan.
- Health Flexible Spending Accounts (FSAs) — Employees can contribute up to $3,300 per year (2025 limit) to a health FSA to pay for eligible medical expenses with pre-tax dollars.
- Dependent Care FSAs — Allows employees to set aside up to $5,000 per year (for married filing jointly) to pay for childcare and elder care expenses with pre-tax dollars.
- Group term life insurance — Up to $50,000 of employer-provided group term life insurance can be included.
- Disability insurance premiums — Short-term and long-term disability premiums can be paid through a Section 125 plan, though this affects the tax treatment of any disability benefits received.
- Accident and health insurance — Hospital indemnity, accident, and critical illness insurance premiums can qualify.
Note that certain benefits do not qualify for Section 125 treatment, including scholarships, employer-provided vehicles, moving expense reimbursements, and most fringe benefits.
How the Tax Savings Work: A Concrete Example
Let’s look at a concrete example to illustrate the tax savings. Suppose you have an employee, Maria, who earns $55,000 per year and contributes $250 per month ($3,000/year) toward her family health insurance premium.
Without a Section 125 plan: Maria pays her $3,000 contribution from after-tax wages. She pays federal income tax (assume 22% bracket), Social Security (6.2%), and Medicare (1.45%) on that $3,000 — a total of about $893 in taxes on her health insurance contribution. Her employer also pays 7.65% FICA on that $3,000, or $230.
With a Section 125 plan: Maria’s $3,000 contribution is made pre-tax. She saves approximately $893 in taxes, and her employer saves $230 in FICA taxes. Between the two of them, the Section 125 plan saves nearly $1,123 on just one employee’s health insurance contribution. Multiply that across your entire workforce and the savings are substantial.
The Three Main Types of Section 125 Plans
Premium-Only Plan (POP)
The simplest and most common cafeteria plan is the Premium-Only Plan, which allows employees to pay their share of health, dental, and vision insurance premiums on a pre-tax basis. A POP requires a formal written plan document but is relatively inexpensive to establish and maintain — often just a few hundred dollars per year through a benefits administrator or broker.
Full Cafeteria Plan
A full cafeteria plan includes a POP plus FSA options (health FSA and/or dependent care FSA). This gives employees more flexibility to redirect income to tax-advantaged accounts for medical and dependent care expenses. A full cafeteria plan requires more administration but offers more tax-saving opportunities for employees.
Simple Cafeteria Plan
Created by the Affordable Care Act for small employers, the simple cafeteria plan allows businesses with 100 or fewer employees to offer cafeteria plan benefits without the nondiscrimination testing required of traditional cafeteria plans. This makes it easier for small businesses to offer FSAs and other benefits without the administrative complexity of annual testing.
Nondiscrimination Rules and Compliance
Section 125 plans are subject to IRS nondiscrimination rules designed to ensure the plan doesn’t disproportionately benefit highly compensated employees or key employees. There are three separate nondiscrimination tests: the eligibility test, the contributions and benefits test, and the key employee concentration test.
If a plan fails nondiscrimination testing, highly compensated employees and key employees lose the tax-advantaged treatment of their benefits — meaning they’d owe income tax on benefits they received tax-free. Rank-and-file employees are not affected by a testing failure.
Simple cafeteria plans (available to businesses with 100 or fewer employees) are deemed to satisfy nondiscrimination requirements if they meet certain contribution requirements, significantly reducing compliance burden for small businesses.
Setting Up a Section 125 Plan
Establishing a Section 125 plan requires a written plan document that meets IRS requirements. The document must specify the plan year, eligible employees, available benefit options, election procedures, and other required terms. While you can find template plan documents online, working with a benefits broker or third-party administrator (TPA) is advisable to ensure compliance.
Once the plan document is in place, you need to collect elections from employees during open enrollment. Elections are generally irrevocable for the plan year unless the employee experiences a qualifying life event (marriage, divorce, birth of a child, change in employment status, etc.) that allows a mid-year election change.
The cost to establish and maintain a Section 125 plan is minimal compared to the tax savings it generates. Many benefits brokers help their clients establish POP plans at no cost as part of their service.
Section 125 and Health Savings Accounts (HSAs)
Section 125 plans and Health Savings Accounts work exceptionally well together. If you offer a High Deductible Health Plan (HDHP) paired with an HSA, you can allow employees to make their HSA contributions through payroll deduction via a Section 125 plan — making the contributions pre-tax for FICA purposes in addition to being pre-tax for income tax purposes. This gives HSA contributions the additional benefit of avoiding the 7.65% FICA tax that they wouldn’t avoid if contributed directly.
Frequently Asked Questions
Can a sole proprietor participate in a Section 125 plan?
No. Sole proprietors, partners in a partnership, members of an LLC taxed as a partnership, and S-corporation shareholders who own more than 2% of the company are not eligible to participate in a Section 125 plan as employees. These individuals have other options for tax-advantaged benefits, but the Section 125 plan benefits their employees, not themselves.
Do I need a third-party administrator for a cafeteria plan?
A Premium-Only Plan can often be administered in-house with minimal effort. However, if you add FSA components, a TPA is strongly recommended to handle election tracking, claims administration, and compliance testing. TPA fees typically range from $300-$1,500 per year depending on plan complexity and employee count.
What happens to unused FSA funds at year end?
FSA funds are “use it or lose it” — unused balances are forfeited at plan year end (with some exceptions). Plans can include a grace period of up to 2.5 months after year end or a carryover of up to $660 (2025 limit), but not both. Dependent care FSAs do not allow a carryover option.
Can I offer different benefit options to different employee groups?
Yes, with important limitations. You can have different benefit options or employer contribution amounts for different classes of employees (e.g., full-time vs. part-time), but the plan must still pass nondiscrimination testing to ensure it doesn’t improperly favor highly compensated employees.
