What Is a Section 125 Cafeteria Plan? How It Works for Employers

The definition in plain English

The name “cafeteria plan” comes from the idea of choice: employees pick from a menu of benefits. The legal core is simpler — the plan gives employees a choice between cash and qualified benefits, and if they choose benefits through a proper salary-reduction election, the tax code generally does not treat that amount as taxable wages.

Most business owners do not need to become Section 125 experts. They do need to understand the basic mechanics well enough to ask good questions of their advisors.

Which benefits can be offered

According to IRS Publication 15-B, qualified benefits that can be offered through a cafeteria plan include:

• Accident and health coverage (for example, the employee's share of health insurance premiums).
• Health flexible spending arrangements (health FSAs).
• Dependent care assistance.
• Contributions to health savings accounts (HSAs), for eligible employees.
• Group-term life insurance (with special rules for coverage above $50,000).
• Adoption assistance (which remains subject to Social Security and Medicare taxes).

Some benefits cannot be offered through a cafeteria plan, including scholarships, educational assistance, most other fringe benefits and long-term care services. Annual contribution limits for FSAs and HSAs are set and adjusted by the IRS.

How it works for employers, step by step

1. The employer adopts a written plan document that describes eligibility, benefits, elections and plan year.
2. Eligible employees make elections before the plan year (or when newly eligible).
3. Payroll reduces each participant's taxable wages by the elected amount each pay period.
4. Federal income tax withholding, Social Security, Medicare and FUTA are generally calculated on the reduced wage amount.
5. Elections generally remain fixed for the plan year unless a permitted change event occurs, such as marriage or birth of a child.
6. The plan is tested each year to confirm it does not discriminate in favor of highly compensated or key employees.

How pre-tax elections can affect employer payroll taxes

Employers pay a 6.2% Social Security tax (up to the annual wage base) and a 1.45% Medicare tax on employee wages — 7.65% combined for most employees. When a pre-tax election reduces an employee's FICA wages, the employer's matching tax on that amount is generally reduced too.

State income and unemployment tax treatment varies; most states follow the federal treatment, but not all do for every benefit. Learn more in understanding employer payroll taxes.

Rules employers must follow

• Written plan: the plan must exist in writing before elections take effect.
• Eligibility: sole proprietors, partners and more-than-2% S corporation shareholders generally cannot participate as employees.
• Nondiscrimination: the plan cannot favor highly compensated individuals as to eligibility, contributions or benefits, and key employees cannot receive more than 25% of total nontaxable benefits.
• Irrevocable elections: mid-year changes are limited to permitted events.
• Health FSA rules: unused amounts are generally forfeited unless the plan offers a permitted carryover or grace period.

A plan that fails these requirements can lose its tax-favored treatment, which is why documentation and annual testing matter.

Considerations for employees

Pre-tax elections generally increase an employee's take-home pay compared with paying the same benefit with after-tax dollars. Because the election reduces Social Security wages, it can slightly reduce the wages used to calculate future Social Security benefits. Employees should understand what they are electing, and communication is part of a well-run plan.

Where Upside Workforce fits

Upside Workforce, powered by 360 Advantage, is designed to bolt onto the benefits an employer already has. It pairs a Section 125 structure — which governs eligibility, elections, salary reductions and payroll treatment, subject to adoption and applicable law — with a separate Self-Insured Medical Expense Benefit Plan and a Personal Health Activation Platform for employees. 360 Advantage guides documents, payroll coordination, employee education, testing and launch.
