Section 125 Preventive Care Plans Explained for Employers

Section 125 of the Internal Revenue Code allows employers to establish cafeteria plans — benefit programs that let employees choose between taxable cash compensation and qualified, tax-exempt benefits. When applied to preventive care through a Self Insured Medical Reimbursement Program (SIMRP), Section 125 creates a mechanism that reduces payroll taxes for employers by an average of $1,119.96 per employee per year while providing employees with comprehensive health and wellness benefits.

What Section 125 Means for Employers

Section 125 authorizes a specific type of employee benefit plan known as a cafeteria plan. Under this provision, employees can elect to receive a portion of their compensation as qualified benefits rather than taxable wages. The key tax advantage: amounts directed to qualified benefits are excluded from federal income tax, Social Security tax (FICA), and in most states, state income tax.

For employers, Section 125 is not a new or obscure provision — it is the same code section that governs traditional pre-tax deductions for employer-sponsored health insurance premiums. What most employers do not realize is that Section 125 can also be used to fund preventive care benefits through a SIMRP, generating substantial payroll tax savings beyond what standard health insurance deductions provide.

How Section 125 Works with the Preventive Care Benefits Program

The Preventive Care Benefits Program uses a Section 125 cafeteria plan as the vehicle for its pre-tax deduction. Each enrolled employee elects a $1,220 monthly pre-tax salary reduction. This election is documented through a proper Section 125 plan document and salary reduction agreement, ensuring full compliance with IRS requirements.

The $1,220 deduction reduces the employee's gross taxable wages for that pay period. Both the employer's and the employee's FICA obligations are calculated on the reduced amount. The employee then receives a WIMPER (Wellness Incentive Medical Plan with Employer Reimbursement) reimbursement of the same $1,220 amount. Because this reimbursement qualifies as an IRC §105(b) medical expense reimbursement, it is not included in taxable income.

The result is a precise payroll restructuring: the employee's take-home pay does not change, but the taxable payroll base is permanently reduced by $1,220 per employee per month.

The Tax Treatment in Detail

Understanding the tax treatment requires following the money through each step:

1. Pre-tax deduction: $1,220 is deducted from the employee's gross pay before FICA and federal income tax are calculated. This reduces the employer's FICA liability by $93.33 (7.65% of $1,220) and the employee's FICA liability by the same amount.
2. Employee tax savings: Depending on the employee's tax bracket and state, the pre-tax deduction typically saves the employee $250 to $350 per month in combined federal income tax, state income tax, and FICA taxes. These savings fund the employee's portion of the preventive care benefits.
3. WIMPER reimbursement: The $1,220 is returned to the employee as a post-tax reimbursement for qualified §213(d) medical expenses. Under IRC §105(b), this reimbursement is excluded from gross income and is not subject to FICA.
4. Net pay unchanged: The combination of the pre-tax deduction and the post-tax reimbursement results in the same net paycheck for the employee. The difference is that FICA taxes are no longer assessed on the $1,220 — a benefit that flows to both the employer and the employee.

Section 125 vs. FSA: A Critical Distinction

Employers sometimes confuse Section 125 preventive care deductions with Flexible Spending Accounts. While both use Section 125 as their legal framework, the mechanisms are fundamentally different:

• No use-it-or-lose-it: FSAs require employees to elect a specific annual amount and forfeit any unused balance at year-end (with limited exceptions). The PCBP's Section 125 deduction is an ongoing payroll reduction with no forfeiture risk.
• No annual election cap: FSAs are subject to IRS annual contribution limits ($3,300 in 2026). The SIMRP pre-tax deduction operates under different provisions and is not subject to the FSA cap.
• Employer savings: While FSAs reduce FICA-taxable wages, they do so only on the relatively small amounts employees choose to contribute. The PCBP creates a $14,640 annual reduction per employee — significantly larger than typical FSA elections.

Employer Savings Math

The FICA savings formula for the employer is straightforward:

These savings require no employer contribution, no premium payments, and no changes to existing health insurance. The Section 125 deduction works alongside any current benefits the employer already provides.

Compliance Requirements for Section 125 Plans

Section 125 plans must meet specific IRS requirements to maintain their tax-advantaged status. The plan must be established through a written plan document that describes the available benefits, eligibility requirements, election procedures, and the employer's contribution methodology. The plan must offer a choice between at least one taxable benefit (cash) and one qualified benefit.

Additionally, Section 125 plans are subject to nondiscrimination testing under IRC §125(b) to ensure that highly compensated employees do not disproportionately benefit from the plan. The Preventive Care Benefits Program handles all plan documentation, compliance filings, and annual nondiscrimination testing as part of its administration through IronGate Business Advisors.

Implementation is completed within 2 to 3 weeks, and savings begin on the next payroll cycle following enrollment. The employer bears no out-of-pocket expenses for plan setup or ongoing administration.
