Understanding Cafeteria Plan Election Options

5/2/2026

A Section 125 Cafeteria Plan gives employees a valuable opportunity: the chance to pay for healthcare and dependent care expenses using pre-tax dollars. However, the process of choosing these benefits—known as making an election—is far from a simple administrative task. It is a strictly regulated process governed by IRS rules.

When you manage a cafeteria plan, you must understand exactly how elections work, when employees can change them, and what documentation you need to keep your plan compliant. A simple mistake in handling an employee's election can jeopardize the tax-advantaged status of your entire plan.

This guide serves as the second installment in our series on cafeteria plans. We will explore the legal framework of Section 125 elections, break down the strict irrevocability rules, and explain how to manage mid-year changes. Whether you are building a new plan or auditing your current procedures, understanding these election options is essential for maintaining compliance.

The Legal Framework of Section 125 Elections

Before we look at the specific types of elections employees can make, we need to understand the legal foundation that makes these pre-tax deductions possible.

The Internal Revenue Code Section 125 states that an employer can offer employees a choice between taxable cash (their regular wages) and qualified non-taxable benefits (like health insurance premiums or flexible spending accounts).

How Pre-Tax Elections Work

An election is a formal agreement between the employee and the employer. The employee agrees to a reduction in their taxable compensation. In return, the employer agrees to apply that specific amount toward a qualified benefit.

Because the employee never officially “receives“ those funds as wages, the money is not subject to federal income tax, Social Security tax, or Medicare tax. This mechanism saves money for both the employee and the employer. If you want to dive deeper into how these deductions interact with standard payroll processes, you can review our Payroll Training resources.

The Role of the Written Plan Document

You cannot process pre-tax elections simply because the IRS allows them in theory. The IRS requires every cafeteria plan to operate under a formal, written plan document.

This document acts as the legal rulebook for your elections. It must explicitly state:

• Which benefits are available for election.
• The maximum amount an employee can elect.
• The specific periods during which employees can make or change elections.
• The rules for how the plan handles mid-year changes.

If an employee makes an election that is not clearly outlined in your written plan document, that election is invalid. Operating without a compliant document is one of the fastest ways to fail an IRS audit.

 

The Irrevocability Rule and the “Plan Year“ Concept

The most critical rule you must teach your employees is the concept of irrevocability. Cafeteria plan elections are not like standard subscription services. Employees cannot turn them on and off whenever they want.

What Does “Irrevocable“ Mean?

Under IRS regulations, once an employee makes an election for a Section 125 benefit, that election is irrevocable for the duration of the plan year.

This means that after the open enrollment period ends and the plan year begins, the employee cannot change their mind. They cannot cancel their health insurance pre-tax deduction to get more take-home pay. They cannot increase their Flexible Spending Account (FSA) contribution just because they scheduled an unexpected surgery. The choice they made before the year started is locked in place.

The IRS enforces this rule strictly to prevent employees from manipulating their taxable income on a month-to-month basis.

Defining the Plan Year

Because elections are tied to the plan year, you must define this period clearly. A plan year is a 12-month period established by the employer in the written plan document. For many organizations, the plan year aligns with the calendar year (January 1 to December 31). However, employers can choose a different 12-month period, such as July 1 to June 30, to align with their specific business or insurance renewal cycles.

Employees make their elections during an open enrollment period that occurs before the new plan year begins. Once the clock strikes midnight on the first day of the plan year, those elections become irrevocable.

 

Mid-Year Changes: Navigating Qualified Life Events (QLEs)

While the irrevocability rule is strict, the IRS understands that life happens. Employees experience major life events that fundamentally change their need for benefits. To accommodate this, the IRS allows mid-year election changes only if the employee experiences a Qualified Life Event (QLE), also known as a qualified status change.

Managing these exceptions is one of the most challenging aspects of Benefits Training. You must ensure that the event meets IRS criteria and that the requested change is directly consistent with the event.

Here is a detailed breakdown of the most common Qualified Life Events.

Change in Marital Status

If an employee's marital status changes, they can adjust their elections to reflect their new family structure.

• Marriage: An employee can add their new spouse to their health plan or increase their FSA contributions to cover the spouse's medical expenses.
• Divorce or Legal Separation: An employee can drop coverage for a former spouse.
• Death of a Spouse: An employee can adjust their coverage levels accordingly.

Change in Number of Dependents

Events that change how many dependents an employee supports also trigger a QLE.

• Birth or Adoption: An employee can add a new child to their health coverage or enroll in a Dependent Care FSA.
• Death of a Dependent: An employee can reduce their coverage level.

Change in Employment Status

A change in employment status for the employee, their spouse, or their dependent can allow for a mid-year election change, provided the change affects benefit eligibility.

• Termination or Commencement of Employment: If an employee's spouse loses their job (and their health insurance), the employee can add the spouse to your cafeteria plan.
• Change in Worksites: If a move causes a change in network coverage availability, the employee may be allowed to select a different plan option.
• Status Changes: Moving from part-time to full-time (or vice versa) if it triggers a change in eligibility for benefits.

The Consistency Rule

The most important caveat to Qualified Life Events is the IRS “Consistency Rule.“ An employee cannot make just any change because they experienced a QLE. The change to their election must be consistent with the event that occurred.

For example, if an employee gets married, adding their new spouse to their health insurance is consistent. However, getting married does not give the employee the right to suddenly drop their own dental insurance or cancel their Dependent Care FSA (unless the spouse is now staying home to care for the child).

Employers must review every requested mid-year change to ensure it passes the consistency test. If you incorrectly approve a change that violates this rule, you risk the compliance of your entire cafeteria plan. Managing the overlap between benefit changes and employee leave can be complex; we recommend reviewing FMLA Training to understand how leave laws impact benefit continuation.

Types of Election Methods: Positive vs. Evergreen (Automatic)

When it comes to gathering elections from your employees, you have two primary methods to choose from. Your written plan document must specify which method you use.

Positive Elections

A positive election requires the employee to take a specific, proactive action to enroll in benefits for the upcoming plan year. They must log into an enrollment portal, sign a paper form, or otherwise explicitly state their choices.

Advantages:

• Provides clear, indisputable proof of the employee's intent.
• Forces employees to review their options annually, ensuring they understand their benefits.

Disadvantages:

• If an employee forgets to complete their enrollment, they lose their benefits for the entire year. This can cause significant frustration and hardship.

Evergreen (Automatic) Elections

An evergreen election, also known as a rolling or automatic election, automatically renews an employee's prior-year elections for the new plan year unless the employee explicitly requests a change.

Advantages:

• Prevents employees from accidentally losing their health coverage if they miss the open enrollment deadline.
• Reduces administrative follow-up for the HR team.

Disadvantages:

• Requires very clear communication. You must notify employees well in advance that their elections will roll over automatically if they take no action.
• Cannot be used for Health Care FSAs or Dependent Care FSAs. The IRS strictly prohibits rolling over FSA contribution amounts; employees must actively elect FSA amounts every single year.

 

Documentation Requirements for Election Forms

Proper documentation is your only defense during an IRS audit. Whether you use paper forms or an online enrollment system, your election documentation must meet specific standards.

What Must Be Included on an Election Form?

A compliant election form (or digital equivalent) should clearly capture the following details:

1. Clear Identification: The employee's name, identification number, and date of signature.
2. Benefit Choices: Exactly which benefits the employee is electing (e.g., Medical Plan A, Dental, Vision).
3. Pre-Tax Authorization: Explicit language where the employee authorizes the employer to reduce their salary on a pre-tax basis to pay for the elected benefits.
4. Irrevocability Acknowledgement: A statement acknowledging that the employee understands the election is irrevocable for the plan year unless they experience a Qualified Life Event.
5. Plan Year Dates: The specific dates of the plan year for which the election applies.

Electronic vs. Paper Elections

The IRS allows employers to use electronic enrollment systems, provided the system includes safeguards to verify the employee's identity and records their digital signature.

If you use an electronic system, you must be able to print a hard copy of the employee's exact election authorization if requested by an auditor. You should keep all election records (paper or digital) for at least three to four years after the tax year in which the elections were effective.
