A Section 125 cafeteria plan lets employees pay their share of group health premiums, and certain other benefits, with pre-tax dollars instead of after-tax income. That simple change lowers payroll taxes for both the employer and the employee, without altering the underlying health plan at all, which makes it one of the easiest cost-reduction tools a small business can put in place.
How the Tax Savings Work
When an employee pays their premium contribution with after-tax dollars, that money has already had federal income tax, Social Security, and Medicare taxes withheld before it ever reaches the premium. Under a Section 125 plan, that same contribution comes out before those taxes are calculated, reducing the employee’s taxable income.
For the employer, this matters too. Payroll taxes, including the employer’s share of Social Security and Medicare, are calculated on taxable wages. Since Section 125 contributions reduce taxable wages, the employer’s payroll tax bill drops along with the employee’s, generally by a few percentage points of whatever premium is run through the plan.
What a Cafeteria Plan Includes
The core structure, often called a Premium Only Plan, covers just the employee’s group health premium contribution. Many employers stop there, since it’s simple to set up and delivers the tax savings without adding complexity to open enrollment.
A fuller cafeteria plan can also include a Flexible Spending Account, letting employees set aside additional pre-tax dollars for medical expenses or dependent care beyond just the premium itself. This adds more moving parts and typically requires third-party administration, but it multiplies the tax advantage for employees who want it.
Why More Small Employers Don’t Already Have One
Setting up a Section 125 plan requires a written plan document and adherence to nondiscrimination rules, meaning the plan generally has to be offered on comparable terms across eligible employees rather than favoring highly compensated staff specifically. It’s a modest administrative step, not a complicated one, but it does need to be done correctly and documented.
We see small employers skip this constantly, not because it isn’t worth it, but simply because nobody flagged it as an option when the group health plan was first set up. It’s one of the more overlooked pieces we check when we take over a group health account.
Common Questions About Section 125 Cafeteria Plans
Does a Section 125 plan cost anything to maintain? There’s typically a modest annual administration cost, especially if it includes a Flexible Spending Account component, but the payroll tax savings on the premium side usually outweigh that cost for most small employers.
Do all employees have to participate? No. Participation is generally optional for eligible employees, though the plan itself has to be offered on a nondiscriminatory basis across the eligible group.
Can a Section 125 plan lower the actual group health premium? No, it doesn’t change what the carrier charges for the plan itself. It changes how the employee’s premium contribution is taxed, which lowers the real cost to both employer and employee without touching the underlying premium.
Is a cafeteria plan the same thing as a Health Savings Account? No. An HSA is a separate savings vehicle tied to a high-deductible health plan. A Section 125 plan is the mechanism that allows HSA contributions, and premium contributions, to be made with pre-tax dollars through payroll.
How do I set one up for my business? It requires a written plan document and proper administration, which we can help coordinate as part of setting up or reviewing your group health coverage.
