Section 125 Cafeteria Plans have been part of the U.S. tax code since 1978. They are the foundational structure of the PCMP and the same mechanism used by every Fortune 500 company to reduce payroll tax liability. Yet most small and mid-size business owners have never heard of them — or have been told they're too complex to implement. The reality is that a properly structured § 125 plan is straightforward, fully compliant, and generates immediate, recurring savings for both the employer and the employee. Here is everything you need to know about how Section 125 works and why it is the most powerful payroll tax reduction tool available to employers.

What is a Section 125 cafeteria plan?

A Section 125 Cafeteria Plan is a written benefit plan that allows employees to choose between taxable cash compensation and certain non-taxable benefits. When an employee elects a non-taxable benefit under a § 125 plan, the value of that benefit is excluded from the employee's gross income — reducing their taxable wages and the employer's FICA tax base. The name 'cafeteria plan' comes from the analogy of choosing from a menu of benefit options. The plan must be in writing, must be offered to all eligible employees on a non-discriminatory basis, and must be administered consistently. Americare handles all of these requirements as part of the PCMP implementation.

The employer FICA savings mechanism

The key to the § 125 savings mechanism is that FICA taxes are calculated on taxable wages — not gross wages. When an employee elects a pre-tax benefit under a § 125 plan, the value of that benefit is excluded from taxable wages before FICA taxes are calculated. This means the employer pays FICA taxes on a smaller wage base, generating direct savings. For every $1,000 of pre-tax benefits elected, the employer saves $76.50 in FICA taxes. For a $1,216/month pre-tax contribution per employee, the employer saves $93.02/month — $1,116.29/year — in gross FICA taxes per enrolled employee.

What benefits can be offered under a § 125 plan?

Section 125 permits a wide range of pre-tax benefit elections. The most common include health insurance premiums (medical, dental, vision), flexible spending accounts (FSAs) for healthcare and dependent care, health savings account (HSA) contributions, accident and disability insurance, group term life insurance, and wellness program contributions. The PCMP uses the § 125 plan to structure a $1,216/month wellness benefit contribution — the first layer of the three-part tax advantage. The specific benefits that can be offered under § 125 are defined by the IRS and must be included in the written plan document.

Section 125 in the PCMP context

In the PCMP, the § 125 Cafeteria Plan is used to structure the $1,216/month pre-tax wellness contribution. This contribution is the first layer of the PCMP's three-part tax advantage. It reduces the taxable wage base for both the employer and the employee, generating FICA savings for both parties. The § 125 plan document is drafted and administered by Americare Health Group as part of the PCMP implementation — the employer does not need to hire a separate plan administrator or benefits attorney. The plan document is customized to the employer's specific workforce and benefit structure.

Compliance requirements

To maintain § 125 compliance, employers must satisfy several requirements. First, the plan must be in writing — a formal plan document that describes the benefits offered, the eligibility rules, the election procedures, and the plan year. Second, employers must provide a Summary Plan Description (SPD) to all eligible employees. Third, the plan must be administered consistently and non-discriminatorily — highly compensated employees cannot receive disproportionate benefits. Fourth, certain IRS forms must be filed annually. Americare Health Group handles all of these requirements as part of the PCMP implementation, providing complete audit-ready documentation.

Non-discrimination testing

Section 125 plans are subject to non-discrimination testing to ensure that the benefits don't disproportionately favor highly compensated employees (HCEs) or key employees. The eligibility test requires that the plan be available to a broad cross-section of employees. The contributions and benefits test requires that the plan not provide disproportionate benefits to HCEs. The key employee concentration test limits the total benefits received by key employees to 25% of total plan benefits. Americare's compliance team conducts annual non-discrimination testing as part of the PCMP administration and provides corrective guidance if any test is at risk of failing.

The election period and irrevocability rule

Under § 125, employees must make their benefit elections before the plan year begins — and those elections are generally irrevocable for the duration of the plan year. This is the 'use it or lose it' rule that applies to FSAs. However, the PCMP's wellness benefit contribution is structured differently from an FSA — it is a recurring monthly benefit that does not accumulate or expire. Employees can change their enrollment status during the plan year only if they experience a qualifying life event (marriage, divorce, birth of a child, change in employment status). Americare's enrollment team manages all election changes and ensures compliance with the irrevocability rules.

Frequently asked questions

Can an employer offer a § 125 plan without implementing the full PCMP? Yes — a standalone § 125 plan can be used to offer pre-tax health insurance premiums, FSAs, or other benefits. However, the PCMP's three-part structure generates significantly more savings than a standalone § 125 plan. Does a § 125 plan require a minimum number of employees? No minimum is required by the IRS, but the PCMP requires at least 10 W2 employees to generate meaningful savings. Can owners participate in a § 125 plan? S-corp shareholders who own more than 2% of the company cannot participate in a § 125 plan. C-corp owners and LLC members can participate. Sole proprietors cannot.
