Payroll Tax Savings Through Section 125 Plan Configuration

How properly structured Section 125 plans reduce employer FICA, FUTA, SUTA, and workers' compensation costs — while also increasing employee take-home pay through pre-tax benefit contributions.

Key Takeaways

  • A properly structured Section 125 plan — also known as a cafeteria plan or premium-only plan — allows employees to pay for certain benefits with pre-tax dollars, reducing both employer and employee payroll taxes.
  • The employer saves on FICA (7.65%), FUTA, SUTA, and workers' compensation premiums on every dollar that employees redirect to pre-tax benefit contributions.
  • Many employers have Section 125 plans that are underutilized — missing eligible benefits or employee populations that could generate additional tax savings.

Section 125 of the Internal Revenue Code is not new. It has been available to employers for decades. Yet many businesses — particularly in the middle market — either do not have a Section 125 plan, have one that is underutilized, or have one that was set up and never reviewed for optimization.

The financial mechanism is straightforward: when employees pay for eligible benefits — health insurance premiums, dental, vision, flexible spending accounts, and certain other benefits — with pre-tax dollars through a Section 125 plan, those dollars are not subject to federal income tax, Social Security tax, or Medicare tax. The employee saves on all three. The employer saves on FICA matching (7.65%), FUTA, SUTA, and in many states, workers' compensation premiums — because the taxable wage base is lower.

Where Employers Leave Money on the Table

No Section 125 plan in place: Every dollar of employee benefit contributions is processed as after-tax — meaning both employer and employee are paying payroll taxes unnecessarily.
Underutilized plan: A Section 125 plan exists but does not include all eligible benefits — missing opportunities that could increase both employer tax savings and employee take-home pay.
Low employee participation: The plan exists and covers the right benefits, but employees have not been educated on the tax savings — leading to lower-than-optimal participation.

When an Independent Review May Help

An independent review of Section 125 plan configuration can identify whether an employer has an optimized plan, whether eligible benefits are included, and whether employee participation could be improved. Blackspire can coordinate a confidential review that identifies specific savings opportunities without disrupting existing payroll or benefits operations.
