Do Section 125 Plans Also Lower
Your Workers' Comp Premiums?

Most employers know that a Section 125 cafeteria plan reduces FICA and FUTA tax exposure. What far fewer realize is that the same pre-tax mechanism can also shrink the payroll base many insurance carriers use to calculate workers' compensation premiums — creating a second, often-overlooked layer of savings on top of the $680-per-employee average payroll tax reduction employers already see.

How Workers' Comp Premiums Are Actually Calculated

Workers' compensation premiums are typically driven by three inputs: your industry classification code, your experience modification rate (e-mod), and — critically for this discussion — your "remuneration," which is essentially your reported gross payroll. Carriers apply a rate per $100 of remuneration to that classification code, then adjust for your e-mod. The bigger your reported payroll figure, the bigger the premium, all else being equal.

The key phrase is "reported payroll." Most state rating bureaus and carriers define remuneration in a way that closely follows gross wages before certain pre-tax reductions, but the treatment of specific pre-tax benefit elections can vary by state and by carrier. Some jurisdictions exclude qualified Section 125 cafeteria plan contributions from the payroll figure used for premium calculation, since those amounts are not considered taxable wages for FICA purposes and are often excluded similarly to certain other fringe benefits.

This is not a universal rule — it depends on your state's rating bureau manual and how your specific carrier applies it — but for employers in states where pre-tax cafeteria plan deductions are excluded from remuneration, a properly structured Section 125 plan can directly lower the payroll number your premium is calculated against.

Why This Matters More Than Most Employers Realize

Payroll tax savings from a Section 125 plan are calculated on the reduction in FICA-taxable wages: employer and employee each avoid 7.65% in Social Security and Medicare tax on the pre-tax contribution amount. That is where the well-known $680 average per-employee savings figure comes from. But if your state and carrier also exclude those same pre-tax dollars from the remuneration used for workers' comp rating, the identical wage reduction can produce a second savings line item — this time on your insurance premium instead of your tax bill.

For labor-intensive industries with higher workers' comp rates — construction, manufacturing, healthcare staffing, hospitality, and transportation — even a modest percentage reduction in reported payroll can translate into a meaningful premium credit at renewal, especially for mid-size employers carrying larger policies.

Because the IRS explicitly recognizes Section 125 pre-tax contributions as excludable from gross income for federal tax purposes (see IRS Publication 15-B), the underlying wage reduction is well documented and defensible — it's simply a matter of confirming with your carrier how your specific state applies that exclusion to premium remuneration.

A Worked Example

Consider a construction subcontractor with 120 W-2 employees and an average workers' comp rate of $6.50 per $100 of payroll — a realistic figure for higher-risk trade classifications. Under a Section 125 preventive healthcare plan, each employee elects roughly $2,000 per year in pre-tax contributions toward preventive care benefits.

That's a total payroll reduction of $240,000 across the workforce ($2,000 x 120 employees). On the payroll tax side alone, at the average savings of $680 per employee, the employer saves approximately $81,600 annually in reduced FICA and FUTA liability. If that same $240,000 reduction is also excluded from the payroll figure used to calculate workers' comp premium — which depends on state rules — the employer could see an additional premium reduction of roughly $15,600 (240,000 x 6.5%) at renewal, assuming no other rating factors change.

Combined, that's over $97,000 in potential annual savings for a single mid-size subcontractor, without cutting a single employee benefit or changing take-home pay in a way that harms workers — because preventive care contributions are typically structured to be cost-neutral or beneficial to employees.

State Variation Is the Catch — Always Verify With Your Carrier

We want to be direct about the limits of this strategy: workers' comp premium rules are set at the state level and administered through rating bureaus (such as NCCI in many states, or independent state funds elsewhere), and treatment of cafeteria plan contributions is not identical everywhere. Some states include all pre-tax benefit deductions in gross payroll for rating purposes; others exclude specific categories. This is different from the federal FICA treatment, which is consistent nationwide because it's governed by the Internal Revenue Code rather than state insurance regulation.

The Department of Labor's Office of Workers' Compensation Programs provides general guidance on wage definitions and covered remuneration (see DOL.gov), but the specific rating manual language always sits with your state's bureau and your carrier's underwriting team. SHRM has also published guidance noting that HR and finance teams should coordinate closely with brokers whenever a new pre-tax benefit is introduced, since payroll-based costs like workers' comp and general liability audits can be affected (see SHRM.org). The practical takeaway: treat the workers' comp savings as a possible bonus, confirm it with your specific carrier, and never treat it as guaranteed until you've seen it reflected in your policy audit.

This is exactly the kind of detail our team walks through during a free consultation — reviewing your current classification codes, payroll reporting practices, and state rules before you assume any premium impact.

Stacking Savings: FICA, Workers' Comp, and Preventive Care ROI

The real power of a well-structured Section 125 plan is that it doesn't force a tradeoff between tax savings and employee wellbeing. The pre-tax dollars employees direct toward preventive care benefits — wellness screenings, telehealth access, and preventive health services — are dollars that also reduce absenteeism and long-term claims exposure, which independently helps your e-mod over time. A lower e-mod compounds with any payroll-base reduction to push premiums down further in future renewal cycles.

In other words, employers who implement these plans correctly often see three simultaneous benefits: immediate payroll tax reduction, a potential one-time or recurring workers' comp premium credit depending on state rules, and a longer-term e-mod improvement tied to a healthier, better-engaged workforce. None of these require raising prices, cutting staff, or reducing benefits — they require restructuring how existing compensation is delivered.

None of this happens automatically, however. It requires accurate payroll coding, proper plan documentation, and clear communication with your workers' comp carrier so the reduced remuneration figure is reflected correctly at your next audit — otherwise you may be paying premium on wages you're no longer required to report.

Getting the Implementation Right

A compliant Section 125 preventive healthcare plan typically takes about four weeks to implement from initial plan design through payroll system integration and employee enrollment. That timeline includes drafting plan documents that satisfy IRS nondiscrimination and eligibility requirements, coordinating with your payroll provider to correctly code pre-tax deductions, and — importantly for the strategy discussed here — looping in your workers' comp broker so your next policy audit reflects the adjusted payroll figures accurately.

Employers with at least 30 W-2 employees are typically strong candidates for this structure, since the fixed administrative costs of running a compliant plan are spread across a large enough payroll base to generate meaningful net savings. Businesses below that threshold can still benefit, but the per-employee math and workers' comp premium impact should be reviewed individually.

If you're already running payroll for 30 or more employees and carry a workers' comp policy with meaningful premium exposure, it's worth a conversation to see whether your state and carrier recognize the exclusion — and to make sure you're not leaving savings on the table in either your tax filings or your insurance renewal.
