Section 125 Cafeteria Plans Explained

Licensed Brokerage20+ Years ExperienceUpdated April 2026

A Section 125 cafeteria plan is an employer-sponsored benefits program that allows employees to pay for certain qualified benefits on a pre-tax basis, reducing both the employee's taxable income and the employer's payroll tax obligations. Named after Section 125 of the Internal Revenue Code, cafeteria plans are the mechanism through which most employer-sponsored benefits achieve their tax-advantaged status. Understanding the different types of cafeteria plan components and their compliance requirements is essential for maximizing tax savings while maintaining a compliant plan.

Premium-Only Plans

A premium-only plan, often abbreviated as POP, is the simplest form of Section 125 cafeteria plan. It allows employees to pay their share of employer-sponsored insurance premiums on a pre-tax basis through payroll deduction. Without a POP in place, employee premium contributions are made with after-tax dollars, meaning the employee receives no tax benefit from the deduction.

The tax savings from a POP are substantial for both employees and employers. An employee in the 22 percent federal tax bracket who contributes $500 per month toward health insurance premiums saves approximately $1,320 per year in federal income tax alone, plus additional savings on state income tax and FICA taxes. The employer saves 7.65 percent in FICA matching taxes on every dollar of pre-tax premium deduction, which for a company with 100 employees contributing an average of $400 per month amounts to approximately $36,720 in annual payroll tax savings.

Implementing a POP requires a written plan document that describes the benefits available, eligibility requirements, election procedures, and the plan year. The plan must comply with Section 125 nondiscrimination rules, which prevent the plan from discriminating in favor of highly compensated employees or key employees in terms of eligibility or benefits. Most employers adopt a POP as the foundation of their cafeteria plan and layer additional components on top of it.

Flexible Spending Accounts

Health flexible spending accounts allow employees to set aside pre-tax dollars to pay for eligible medical, dental, and vision expenses not covered by insurance. The annual contribution limit for health FSAs is set by the IRS and adjusted for inflation each year. Employees elect their annual contribution amount during open enrollment, and the full election amount is available on the first day of the plan year, even though contributions are deducted evenly from paychecks throughout the year.

The use-it-or-lose-it rule historically meant that any unused FSA balance at the end of the plan year was forfeited. However, employers now have two options to provide limited relief. The carryover provision allows employees to carry over a specified amount of unused funds into the next plan year. Alternatively, the grace period provision extends the period for incurring eligible expenses by up to two months and 15 days after the plan year ends. An employer may offer one of these provisions but not both, and neither is required.

Dependent care flexible spending accounts, also called dependent care assistance programs, allow employees to set aside pre-tax dollars to pay for eligible dependent care expenses that enable the employee and their spouse to work. The annual contribution limit is $5,000 for married filing jointly or single filers, and $2,500 for married filing separately. Unlike health FSAs, dependent care FSAs operate on a pay-as-you-go basis, meaning only the amount actually contributed to date is available for reimbursement.

Health Savings Account Integration

While health savings accounts are authorized under Section 223 of the Internal Revenue Code rather than Section 125, employer contributions and employee pre-tax payroll deductions into HSAs are typically facilitated through the Section 125 cafeteria plan. When HSA contributions flow through a cafeteria plan, the employee avoids both income tax and FICA taxes on contributions, producing greater tax savings than direct individual contributions, which avoid income tax but not FICA.

To be eligible for an HSA, the employee must be enrolled in a qualified high-deductible health plan and must not be covered by any non-HDHP health plan, including a general-purpose health FSA or an HRA that pays first-dollar medical expenses. Employers offering both FSAs and HSAs must structure their FSA as a limited-purpose FSA that covers only dental and vision expenses, or a post-deductible FSA that only reimburses expenses after the HDHP deductible is met.

Employer contributions to HSAs are excluded from the employee's gross income and are not subject to FICA or FUTA taxes. Many employers contribute a fixed annual amount to each participating employee's HSA, often prorated for mid-year enrollees. These employer contributions, combined with pre-tax employee payroll deductions, are subject to the annual HSA contribution limits, which include both employer and employee contributions. Catch-up contributions are available for employees aged 55 and older.

Nondiscrimination Testing Requirements

Section 125 cafeteria plans must satisfy nondiscrimination requirements to maintain their tax-advantaged status. Three primary tests apply: the eligibility test, which ensures the plan does not discriminate in favor of highly compensated employees regarding participation eligibility; the contributions and benefits test, which ensures the plan does not provide disproportionate benefits to highly compensated or key employees; and the key employee concentration test, which limits the share of total cafeteria plan benefits that may go to key employees.

Health FSAs are subject to additional nondiscrimination testing under Section 105(h), which prohibits self-insured medical reimbursement plans from discriminating in favor of highly compensated individuals. If a health FSA fails Section 105(h) testing, the excess reimbursements received by highly compensated individuals become taxable income. Dependent care FSAs are subject to Section 129 nondiscrimination testing, which includes its own eligibility, contributions and benefits, and concentration tests.

Employers should conduct nondiscrimination testing annually before the start of the plan year to identify and address potential failures before they result in adverse tax consequences. Common corrective actions include expanding plan eligibility, adjusting employer contribution levels, or limiting the elections of highly compensated employees. Working with a benefits attorney or plan compliance specialist is advisable for employers with complex workforce demographics.

Plan Document and Administration Requirements

Every Section 125 cafeteria plan must be established and maintained under a written plan document. The plan document must describe all benefits available under the plan, establish rules for eligibility and participation, define the plan year, set forth the election and revocation procedures, specify the maximum period of coverage, and identify the procedure for making contributions. The plan must operate in accordance with its written terms, and any amendments must be adopted in writing before they take effect.

Election changes under a cafeteria plan are generally locked for the plan year once the enrollment period closes. Mid-year election changes are only permitted when the employee experiences a qualifying change in status event that is consistent with the election change. Recognized change-in-status events include marriage, divorce, birth or adoption of a child, death of a dependent, change in employment status of the employee or spouse, change in dependent eligibility, and change in residence that affects plan options. The plan document must specify which change-in-status events are recognized and the corresponding permitted election changes.

Plan administration involves processing payroll deductions, managing enrollment and election changes, adjudicating and paying FSA claims, maintaining records of all participant elections and transactions, and preparing required tax reporting. Many employers outsource cafeteria plan administration to a third-party administrator who specializes in Section 125 compliance, claims processing, and recordkeeping.

Frequently Asked Questions

A premium-only plan is the simplest type of cafeteria plan and only allows employees to pay insurance premiums on a pre-tax basis. A full cafeteria plan includes additional components beyond pre-tax premiums, such as health flexible spending accounts, dependent care flexible spending accounts, and HSA contributions facilitated through payroll deduction. Most employers start with a POP and add FSAs and other components as their benefits program matures. All of these arrangements operate under the Section 125 cafeteria plan umbrella.

Generally, Section 125 elections are irrevocable for the plan year once made. Mid-year changes are only permitted when the employee experiences a qualifying change in status event, such as marriage, divorce, birth or adoption of a child, loss of other coverage, or a change in employment status. The requested change must be consistent with the triggering event. For example, the birth of a child permits adding the new dependent but would not permit dropping coverage. Your plan document must specify which events are recognized and what changes are allowed.

Employers save 7.65 percent in FICA matching taxes on every dollar of employee compensation that is redirected through a Section 125 plan as pre-tax deductions. For an employer with 200 employees whose average pre-tax deduction is $6,000 per year across premiums, FSA contributions, and HSA contributions, the annual FICA tax savings would be approximately $91,800. Additional savings may apply to state unemployment taxes depending on the state. These savings typically far exceed the cost of establishing and administering the plan.

Under the use-it-or-lose-it rule, any unused health FSA balance is forfeited at the end of the plan year unless the plan includes one of two optional provisions. The carryover provision allows a participant to carry over a specified dollar amount of unused funds into the next plan year. The grace period provision extends the claims incurrence period by up to two months and 15 days after the plan year ends. The employer may adopt one of these provisions but not both, and neither is mandatory. Careful contribution planning based on anticipated expenses is the best way for employees to minimize forfeiture risk.
