Here is one of the rare setups in tax where the employer and the employee both come out ahead. A Section 125 cafeteria plan lets your team pay for certain benefits with pre-tax dollars, which lowers their taxable income and, at the same time, trims your payroll tax bill. Nobody writes a bigger check, yet both sides keep more money. That is why these plans are everywhere, from big companies to small shops.
The name throws people off. It has nothing to do with lunch. It is called a cafeteria plan because employees pick and choose the benefits they want from a menu, and it is called Section 125 because that is the part of the Internal Revenue Code that authorizes it. Put together, a Section 125 plan is simply an employer-sponsored plan that allows employees to pay for qualified benefits before taxes are taken out.
If you are an employer weighing whether to offer one, or a business owner who keeps seeing "Section 125" on payroll paperwork and wants to understand it, this guide is for you. It covers what a cafeteria plan is, how the tax savings actually work, the types of plans you can offer, which benefits qualify, the rules you have to follow, and how to set one up without tripping over compliance.
At its core, a Section 125 plan is a separate written plan maintained by an employer that meets the requirements of Section 125 of the Internal Revenue Code, often written as IRC Section 125. It lets employees choose between taking their full pay as taxable cash or redirecting some of it, before tax, to pay for qualified benefits like health insurance. That choice is the whole idea.
The rules say the plan must offer at least one taxable benefit, usually cash in the form of regular salary, and at least one qualified benefit that is not taxed. In plain terms, these plans allow employees to pay for the benefits they pick with untaxed dollars. Employees then build their own package from what the employer puts on the menu. Because the money set aside for qualified benefits comes out before taxes, it never counts as taxable income in the first place. This is different from an ordinary benefit deduction, and it is the mechanism that makes the savings possible. Since the whole thing runs through your payroll system, clean payroll setup is where a Section 125 plan lives or dies.
This is the part worth slowing down on, because it is where the value comes from. When an employee elects to pay for a benefit through a Section 125 plan, that amount is deducted from their gross pay before federal income tax and before Social Security and Medicare taxes are calculated. Their taxable wages drop, so they owe less in both income tax and payroll tax.
The employer wins too, and this surprises people. Because the employee's taxable wages are lower, the employer's matching share of Social Security and Medicare tax, currently 7.65 percent, is also lower on those dollars. So every dollar an employee runs through the plan saves the business payroll tax as well. On a full workforce, those section 125 deductions add up to real money, which is why even cost-conscious small employers offer a plan. It genuinely is a win for both sides, not marketing spin.
Cafeteria plans are not one-size-fits-all. There are a few common types, and the right one depends on how much you want to offer.
The simplest is the premium only plan, often called a POP. It does one thing: it lets employees pay their share of health plan premiums with pre-tax dollars. Many small businesses start here because it is easy to run. A step up is a plan built around flexible spending accounts, where employees set aside pre-tax money for out-of-pocket medical expenses through a health FSA, or for a dependent care assistance program to cover childcare and similar costs. A full cafeteria plan combines several benefits into one menu, giving employees the widest choice. Finally, a simple cafeteria plan is a special version for smaller employers, generally those with 100 or fewer employees, that provides a safe harbor from some of the nondiscrimination testing in exchange for meeting set contribution and eligibility rules. Choosing among these is really about matching the plan to the size and needs of your team.
A cafeteria plan can only offer benefits that Section 125 allows on a pre-tax basis, so the menu is defined by the rules. The common qualified benefits include health, dental, and vision insurance premiums, contributions to a health FSA for medical expenses, contributions to a health savings account, group term life insurance up to a limit, and a dependent care assistance program.
Two of these have annual dollar limits worth knowing. The health FSA has an IRS contribution limit that adjusts most years, set at $3,400 for 2026. The dependent care assistance limit sat at $5,000 for nearly four decades, but the One Big Beautiful Bill Act raised it to $7,500 per household, or $3,750 for married individuals filing separately, starting in 2026, though employers can still set a lower cap in their own plan. Just as important is what a cafeteria plan cannot include. It generally cannot be used to defer compensation, with a 401(k) plan being the notable exception, and it cannot cover benefits like long-term care insurance or most other fringe benefits. Getting the menu right is a compliance question, not just a design choice.
A Section 125 plan comes with strings attached, and this is where employers get into trouble if they are casual about it. First, the plan has to be in writing. You need a formal written plan document that lays out the benefits, eligibility, and rules before the plan can take effect, and a summary plan description for participants. A handshake arrangement does not qualify.
Second, there are nondiscrimination rules. Under the IRS rules for Section 125 plans, the plan cannot favor highly compensated or key employees in who can participate or in the benefits they receive. If it does, those favored employees can lose the tax break, which defeats the purpose. This is exactly the testing the simple cafeteria plan safe harbor is designed to sidestep for smaller businesses. Third, elections are generally locked in for the plan year. Once an employee decides how much to contribute, they usually cannot change it mid-year unless they have a qualifying life event, such as marriage, divorce, the birth of a child, or a change in employment. One more point that catches owners off guard: certain people cannot participate at all, including self-employed individuals, partners in a partnership, and more-than-2-percent shareholders of an S corporation, because the tax code does not treat them as employees for this purpose.
Employers that sponsor a Section 125 plan follow a clear sequence, and getting one off the ground is very doable. You start by deciding which benefits to offer and having a written plan document prepared, since that document is the legal foundation. From there you communicate the plan to employees and run an enrollment period so they can choose their benefits and set their contribution amounts for the coming plan year.
The ongoing plan administration then shifts to payroll and compliance. Each pay period, the elected amounts have to be deducted pre-tax and applied correctly, the plan has to pass its nondiscrimination testing, and mid-year changes tied to qualifying events have to be handled properly. None of this is exotic, but it does have to be done consistently, because a plan that is administered sloppily can lose its tax-favored status. That is usually the point where employers decide they would rather hand the mechanics to someone who does it every day.
Worth saying plainly. A Section 125 plan is straightforward in concept but detail-heavy in practice: the written document, pre-tax payroll deductions calculated correctly every cycle, nondiscrimination testing, and clean handling of enrollment and qualifying-event changes. Any one of those going wrong can undo the tax benefit.

What is a Section 125 cafeteria plan? A Section 125 cafeteria plan is an employer-sponsored benefit plan, authorized by Section 125 of the Internal Revenue Code, that lets employees pay for certain qualified benefits with pre-tax dollars. It is called a cafeteria plan because employees choose the benefits they want from a menu, which must include at least one taxable benefit like cash and at least one qualified nontaxable benefit. Because the money is set aside before taxes, it lowers the employee's taxable income and the employer's payroll tax, which is why the plan benefits both sides.
How does a Section 125 plan save on taxes? When an employee runs a benefit through a Section 125 plan, the amount is deducted from gross pay before federal income tax and before Social Security and Medicare taxes are figured. That lowers the employee's taxable wages, so they pay less income tax and less payroll tax. The employer also saves, because its matching Social Security and Medicare tax of 7.65 percent applies to those lower wages. So the same benefit costs less for the employee and reduces payroll taxes for the business at the same time.
What are the types of Section 125 plans? There are a few common types. A premium only plan lets employees pay their share of insurance premiums pre-tax and is the simplest to run. A flexible spending account plan lets employees set aside pre-tax money for medical expenses through a health FSA or for childcare through a dependent care assistance program. A full cafeteria plan bundles several benefits into one menu. A simple cafeteria plan is a version for employers with 100 or fewer employees that offers a safe harbor from certain nondiscrimination testing if set requirements are met.
What benefits can a cafeteria plan include? A cafeteria plan can include qualified benefits that Section 125 permits on a pre-tax basis. Common ones are health, dental, and vision insurance premiums, health FSA contributions for medical expenses, health savings account contributions, group term life insurance up to a limit, and a dependent care assistance program. It generally cannot include benefits that defer compensation, other than a 401(k), and cannot cover items like long-term care insurance. The health FSA and dependent care limits are set by law and adjust periodically, so the current figures should be confirmed each year.
Who can participate in a Section 125 cafeteria plan? Common-law employees of the employer can participate, including part-time and full-time staff who meet the plan's eligibility rules. However, certain owners cannot participate on a pre-tax basis, because the tax code does not treat them as employees for Section 125 purposes. That group includes self-employed individuals, partners in a partnership, and shareholders who own more than 2 percent of an S corporation. Those owners may still sponsor a plan for their employees, but they generally cannot take the pre-tax benefit for themselves through the cafeteria plan.
Can employees change their elections mid-year? Usually not. Once an employee makes their elections for the plan year, those choices are generally locked in and cannot be changed until the next enrollment period. The main exception is a qualifying life event, such as getting married or divorced, having or adopting a child, a change in employment status, or a similar change in family or work circumstances. When a qualifying event happens, the employee can make a mid-year change that is consistent with that event, within the window the plan allows.
What is a simple cafeteria plan? A simple cafeteria plan is a type of Section 125 plan created for smaller employers, generally those that averaged 100 or fewer employees over the prior two years. Its main advantage is a safe harbor: if the employer meets specific minimum contribution and eligibility requirements, the plan is treated as automatically satisfying the nondiscrimination tests that apply to regular cafeteria plans. This removes a significant compliance burden and makes it easier for small businesses to offer pre-tax benefits without worrying about failing testing that favors highly compensated employees.
