How to Reduce Payroll Taxes: 5 Strategies for Small Businesses

The Social Security Administration reports employers paid $496 billion in FICA taxes in 2023. For small and mid-sized businesses, payroll taxes represent one of the largest recurring expenses on the books — 7.65% on every dollar of taxable wages, with no standard deductions or credits to offset the obligation. According to the BLS, benefits account for approximately 31% of total employee compensation costs, and FICA is a significant contributor to that figure.

The good news: there are legal, IRS-compliant strategies that reduce the wages on which FICA is calculated. Not all are equal in impact, but each one lowers your taxable payroll base. Here are five strategies every small business owner should evaluate.

1. Section 125 Cafeteria Plans

A Section 125 cafeteria plan allows employees to pay for qualified benefits — particularly health insurance premiums — on a pre-tax basis. When premiums are deducted before FICA is calculated, the employer's taxable payroll shrinks by the amount of the deduction. If your employees are currently paying health insurance premiums on a post-tax basis, you are overpaying FICA on every payroll cycle.

Most employers with group health insurance already have a Section 125 plan in place, but many do not realize how much further it can be extended. Beyond health premiums, Section 125 can be used to fund dental, vision, dependent care FSAs, and — critically — preventive care programs structured as Self Insured Medical Reimbursement Programs. The broader the qualified deductions running through Section 125, the greater the FICA reduction.

2. HSA Contributions

Employer contributions to Health Savings Accounts are exempt from FICA taxes under IRC §106(d). For 2026, the HSA contribution limit is $4,300 for individual coverage and $8,550 for family coverage. If the employer contributes directly to an employee's HSA, that amount is excluded from the employee's gross income and is not subject to FICA for either party.

The limitation: HSAs require a High Deductible Health Plan (HDHP), which may not suit every workforce. Additionally, employer HSA contributions are a direct expense — the employer is writing a check. The FICA savings on those contributions partially offset the cost, but the employer is still spending money to generate the tax benefit.

3. SIMRP-Based Preventive Care Programs

This is the highest-impact strategy on this list, and it is the approach used by the Preventive Care Benefits Program. A Self Insured Medical Reimbursement Program (SIMRP) structured under IRC §105(b) and delivered through a Section 125 cafeteria plan creates a $1,220 monthly pre-tax deduction per employee. That deduction reduces the employer's FICA-taxable payroll by $14,640 per employee per year.

The math is precise: $1,220 × 7.65% employer FICA rate = $93.33 per employee per month, or $1,119.96 per employee per year. For a company with 50 employees, that is $55,998 in annual FICA savings.

What separates the SIMRP approach from other strategies is that it requires no employer contribution. The program is funded through the pre-tax/post-tax payroll restructuring itself. Employees receive a $1,220 post-tax WIMPER reimbursement that qualifies under IRC §105(b) as a medical expense reimbursement excluded from gross income. Their net pay remains unchanged. The employer's only outcome is reduced FICA liability and a comprehensive preventive care benefit for the workforce — including over 1,000 preventive prescriptions, unlimited telemedicine, $150,000 in life insurance, and mental health counseling.

The legal foundation rests on two code sections: IRC §125 authorizes the pre-tax salary reduction, and IRC §105(b) excludes the employer-provided medical reimbursement from taxable income. Together, they create a permanent reduction in FICA-taxable wages that operates on every payroll cycle. Use the savings calculator to estimate your specific FICA reduction based on headcount.

4. Retirement Plan Contributions

Employer contributions to qualified retirement plans — 401(k), SIMPLE IRA, SEP IRA — are not subject to FICA taxes. Employee elective deferrals to a traditional 401(k) reduce federal income tax but remain subject to FICA, so the benefit for payroll tax purposes flows primarily through employer matching contributions.

A common employer match of 3% to 6% of salary does reduce the FICA-taxable portion of compensation, but only on the employer's contribution amount. For an employee earning $60,000 with a 4% match, the employer contributes $2,400 — saving $183.60 in FICA annually. This is meaningful, but it requires the employer to spend $2,400 to save $183.60. The return on investment is modest compared to strategies that generate savings without requiring employer spending.

5. Qualified Transportation Benefits

Under IRC §132(f), employers can offer pre-tax deductions for qualified transportation expenses — transit passes, vanpooling, and qualified parking. For 2026, the monthly limit is $325 for transit and $325 for parking. When employees elect these benefits through a Section 125 plan, the pre-tax deduction reduces FICA-taxable wages for both the employer and employee.

The FICA savings per employee are relatively small — a maximum of $596.70 per year if an employee maxes out both transit and parking — and participation varies significantly based on geography and workforce demographics. Urban employers with commuter-heavy workforces will see more benefit than suburban businesses where most employees drive.

Comparing the Five Strategies

Each strategy has merit, but they differ substantially in impact, employer cost, and ease of implementation. Section 125 cafeteria plans and transportation benefits are relatively simple but generate modest savings. HSAs and retirement contributions deliver tax benefits but require direct employer spending. The SIMRP-based preventive care program stands alone as the strategy that generates the largest per-employee FICA savings with no employer out-of-pocket expenses.

These strategies are not mutually exclusive. A business can implement all five simultaneously. But for employers looking for the single highest-impact move, learn more about how the Section 125 preventive care approach reduces payroll taxes starting on the next pay cycle.
