What Is a Cafeteria Plan?

A cafeteria plan, formally known as a Section 125 plan, is a type of employee benefit plan that allows participants to choose from a variety of pre-tax benefits. Named after Section 125 of the Internal Revenue Code that authorizes these arrangements, cafeteria plans have become a cornerstone of competitive employee benefits packages.

The fundamental concept is simple: employees are given the choice between receiving their full salary or directing a portion toward qualified benefits before taxes are calculated. This "salary reduction" arrangement means employees pay less in taxes while still receiving valuable benefits.

According to IRS regulations, a cafeteria plan must offer at least one taxable benefit (usually cash/salary) and at least one qualified non-taxable benefit. This choice element is what distinguishes cafeteria plans from other benefit arrangements.

Why Is It Called a Cafeteria Plan?

The term "cafeteria plan" comes from the way these benefits work—just like walking through a cafeteria line and choosing the foods you want, employees can select the benefits that best fit their individual needs from a "menu" of options.

A young, single employee might prioritize different benefits than a parent with three children. A cafeteria plan allows both to customize their benefit selections, potentially including:

  • Health insurance (medical, dental, vision)
  • Health Flexible Spending Account (FSA)
  • Dependent Care FSA
  • HSA contributions
  • Life insurance
  • Disability coverage
  • Cash (taking more salary instead of benefits)

This flexibility makes cafeteria plans particularly valuable for diverse workforces with varying benefit needs.

Benefits of a Section 125 Cafeteria Plan

For Employees:

  • Significant Tax Savings: Every dollar contributed to qualified benefits avoids federal income tax, Social Security tax, Medicare tax, and usually state income tax—typically saving 25-40%
  • Customized Benefits: Choose benefits that match personal and family needs
  • Higher Take-Home Pay: Even though gross income appears lower, net pay often increases due to tax savings
  • FSA Advantages: Access full annual FSA election from day one of the plan year

For Employers:

  • FICA Tax Savings: Save 7.65% on every dollar employees contribute through the plan
  • Competitive Benefits Package: Attract and retain talent without increasing costs
  • Reduced Payroll-Based Costs: Lower workers' comp premiums and Federal Unemployment Tax (FUTA) liability, both calculated on the taxable wage base that Section 125 reduces
  • Employee Satisfaction: Workers appreciate the flexibility and tax savings
  • Tax-Deductible: Plan administration costs are fully deductible business expenses

2026 Updates: What's New for Cafeteria Plans This Year

The One Big Beautiful Bill Act (OBBB) introduced the most significant cafeteria plan changes in years. Three areas directly affect how employers administer their Section 125 plans in 2026.

1. Higher contribution limits across all account types.

The Health FSA limit increased to $3,400 (from $3,300), the Dependent Care FSA limit rose to $7,500 per household (from $5,000), and HSA limits climbed to $4,400 for self-only and $8,750 for family coverage. These increases mean higher per-employee FICA savings for employers and more tax shielding for employees. A fully enrolled employee who maxes an FSA, DCFSA, and health premiums now has more pre-tax dollars at work than any prior plan year.

2. Box 14b Treasury Tipped Occupation Codes for hospitality employers.

For employers in tipped industries—restaurants, hotels, delivery services—the OBBB created a new Box 14b requirement on the W-2. Employees in tipped occupations can now deduct up to $25,000 in tips from federal income tax, but only if their employer reports the correct Treasury Tipped Occupation Code in Box 14b. This code must be coordinated with your cafeteria plan administration: tipped employees can stack the No Tax on Tips deduction with their Section 125 pre-tax elections for maximum take-home benefit. For the full Box 14b setup guide, see our W-2 Box 14 codes explained.

3. Trump Account contributions (Box 12, Code TA) as a new optional benefit.

Employers can now contribute up to $2,500 per year tax-free into a Trump Account for an employee's child under 18. These contributions are reported in Box 12 under Code TA. While Trump Accounts are not administered through a traditional Section 125 plan, they represent a new employer-funded benefit that sits alongside the cafeteria plan in the overall benefits package. For how these new codes appear on the W-2 alongside S125, see our Section 125 on W-2 guide.

Components of a Cafeteria Plan

A Section 125 cafeteria plan typically includes several components that can be mixed and matched based on employer offerings:

Premium Payment Component

This is the most basic element, allowing pre-tax payment of employee-share insurance premiums. Almost every cafeteria plan includes this component because it's simple and provides immediate value.

Health FSA

A Health Flexible Spending Account lets employees set aside pre-tax money for eligible medical, dental, and vision expenses not covered by insurance. The 2026 contribution limit is $3,400. Plans may also offer a carryover of up to $680 into the following plan year, or a 2.5-month grace period—but not both simultaneously.

Dependent Care FSA

This account covers childcare or eldercare expenses for dependents, allowing employees to work. The 2026 annual limit is $7,500 per household ($3,750 if married filing separately). This is the single largest limit increase in the OBBB package and represents a meaningful jump for working parents who were previously capped at $5,000.

Health Savings Account (HSA) Contributions

When paired with a high-deductible health plan (HDHP), cafeteria plans can include pre-tax HSA contributions. HSAs offer triple tax advantages and funds roll over indefinitely. The 2026 HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. Note that employees cannot contribute to both a standard Health FSA and an HSA in the same year—only a Limited Purpose FSA (restricted to dental and vision) is compatible with an HSA.

IRS Rules and Requirements

The IRS imposes specific requirements on Section 125 cafeteria plans:

Written Plan Document

Every cafeteria plan must have a formal written document that includes:

  • Description of available benefits
  • Eligibility requirements
  • Election procedures and periods
  • How contributions will be made
  • Plan year dates
  • Maximum amounts for FSAs

Election Requirements

  • Elections must be made BEFORE the start of the plan year
  • Elections are irrevocable for the plan year (with limited exceptions)
  • Mid-year changes only allowed for qualifying life events
  • New employees must elect within 30 days of eligibility

Qualifying Life Events

The only circumstances allowing mid-year election changes include:

  • Marriage or divorce
  • Birth, adoption, or placement of a child
  • Death of a spouse or dependent
  • Change in employment status (employee, spouse, or dependent)
  • Dependent becoming eligible/ineligible due to age
  • Change in residence affecting benefit eligibility

Non-Discrimination Testing

The IRS requires that cafeteria plans not discriminate in favor of highly compensated employees (HCEs) or key employees. In 2026, HCEs are defined as employees earning over $135,000, and Key Employees are owners or officers earning over $235,000. Three primary tests must be passed:

  1. Eligibility Test: The plan must not require employees to complete more than 3 years of employment to participate, and must benefit a reasonable classification of employees.
  2. Contributions and Benefits Test: HCEs cannot receive disproportionately higher benefits than non-HCEs.
  3. Key Employee Concentration Test: No more than 25% of the plan's total benefits can go to key employees.

Failing non-discrimination tests results in HCEs losing their pre-tax benefit status—those contributions become taxable income for the affected employees, and the employer owes back FICA on the reclassified wages. Non-HCEs are not affected and keep their tax savings. Proper plan design and annual NDT monitoring are the most reliable ways to avoid this outcome.

What Does It Cost Employers?

The cost of implementing and maintaining a cafeteria plan varies based on complexity:

  • Premium Only Plan (POP): Minimal cost—often under $500 for setup and very low ongoing fees
  • FSA Administration: Typically $4-8 per participant per month, covering claims processing, debit cards, and compliance
  • Full Cafeteria Plan: Higher setup costs but more comprehensive benefits

The important thing to remember: the FICA tax savings employers realize typically far exceed the plan administration costs. A business with 25 employees might save $8,000+ annually in payroll taxes while spending only $1,500-2,500 on plan administration.

Who Benefits Most from a Section 125 Cafeteria Plan

Any employer with at least one W-2 employee can establish a Section 125 plan, but the ROI is not equal across all industries. Four employer types see the highest returns in 2026.

Hospitality and tipped-wage employers. Restaurants, hotels, catering companies, and delivery services benefit from a unique double stack in 2026: the Section 125 FICA savings on premiums and FSA elections, combined with the new OBBB No Tax on Tips provision for tipped employees. A tipped employee enrolled in a Section 125 plan and claiming the Box 14b tip deduction can reduce their effective federal tax rate to near zero on a significant portion of their income. The employer captures the FICA savings on the pre-tax elections and avoids the matching payroll tax on those wages entirely.

Healthcare employers. Medical practices, dental offices, and healthcare staffing firms tend to have higher benefit elections per employee (employees in healthcare are typically more benefit-savvy) and diverse workforces that value FSA and DCFSA options. Higher average elections translate directly into higher FICA savings per employee.

Construction and prevailing wage contractors. Federal and state prevailing wage contracts require employers to pay a "fringe" benefit rate per hour worked. Routing those fringe dollars through a Section 125 plan satisfies the prevailing wage requirement while generating FICA savings on every dollar—a structure that reduces the employer's net labor cost on covered projects. For a full breakdown of this approach, see our guide to FICA tax savings for employers.

Professional services firms. Law firms, accounting firms, and consulting companies typically have high average compensation, making the DCFSA limit increase to $7,500 especially valuable. A dual-income household at a professional services firm where both partners maximize DCFSA elections through their respective employers can shelter $15,000 annually from federal taxes—funding nearly 100% of daycare costs tax-free.

Frequently Asked Questions

What's the difference between a cafeteria plan and a Section 125 plan?
There is no difference. Section 125 refers to the IRS code that authorizes these plans, while "Cafeteria Plan" is the name given because employees can select from a "menu" of different benefits.
Can a small business with just 5 employees set up a cafeteria plan?
Yes. Small businesses can and should implement these plans. The FICA tax savings alone often exceed the cost of the plan, making it a net-positive financial decision for the business.
Do cafeteria plans affect Social Security benefits?
Because pre-tax contributions reduce your reported Social Security wages, there may be a very minor impact on future benefit calculations. However, for most, the massive immediate tax savings (25-40%) are far more valuable.
What happens if our company fails non-discrimination testing?
If a plan fails, highly compensated employees (HCEs) may lose the tax-free status of their contributions and must report them as taxable income. Non-HCEs are not affected and keep their tax savings. The employer also owes back FICA on the reclassified HCE wages, making proper NDT monitoring essential for any company with owners or officers earning over $135,000 in 2026.
Can we add a cafeteria plan mid-year?
Yes, you can start a plan mid-year. However, the pre-tax salary reductions can only apply to salary earned after the plan is officially in place.
What is the difference between a Premium Only Plan (POP) and a full cafeteria plan?
A Premium Only Plan (POP) is the simplest form of a Section 125 plan: it allows employees to pay their health, dental, and vision insurance premiums using pre-tax dollars. A full cafeteria plan layers in FSA accounts, Dependent Care FSA, HSA integration, and potentially supplemental benefits — capturing more tax savings per employee. Most Summit Health Benefits clients start with a POP and add FSA functionality as employee participation grows. Either structure generates employer FICA savings from day one.
What happens to FSA funds employees don't use by year-end?
The use-it-or-lose-it rule applies to Health FSA balances. Plans may offer one of two relief options: a 2.5-month grace period (unused funds remain available through March 15 of the following year) or a carryover of up to $680 (the 2026 limit). A plan cannot offer both simultaneously — the employer must choose one option or neither when the plan is designed. Employees who do not spend or roll over their unused balance forfeit it at the end of the relief period. Dependent Care FSA funds follow the same forfeit rule with no carryover option.
Can employees in New Jersey or Pennsylvania use a Section 125 cafeteria plan?
Yes, with one important distinction. New Jersey and Pennsylvania do not conform to federal Section 125 pre-tax treatment for state income tax purposes. Employees in these states still save federal income tax and FICA taxes through a Section 125 plan — they simply cannot exclude their contributions from NJ or PA state taxable wages. Since the federal tax savings (income tax plus FICA) are the larger share of the total benefit, participation is still strongly advantageous for employees in these states. Payroll systems must be configured to apply pre-tax treatment for federal purposes while maintaining a separate state taxable wage calculation.
