Section 125 Qualifying Life Events: When Employees Can Change Elections Mid-Year

• Section 125 elections are generally locked for the plan year, and 26 CFR 1.125-4 lists the events that allow a change.
• The consistency rule says the new election must correspond with and be triggered by the event, per 26 CFR 1.125-4(c).
• Section 125 does not require a plan to allow any of these changes, so the plan document decides, per 26 CFR 1.125-4.
• IRS Notice 2014-55 added two events: a drop below 30 hours a week and enrolling in a Marketplace plan.
• The 2026 health FSA limit is $3,400 and the dependent care limit is $7,500, per IRS Publication 15-B (2026).

An employee gets married in June and asks HR to add a spouse to the health plan. Another wants to drop coverage after starting a spouse's job. Your answer depends on whether the plan document allows the change and whether the event fits the IRS list.

What are Section 125 qualifying life events?

Section 125 qualifying life events are the events that let a participant revoke or change an election during the plan year. The IRS calls most of them "changes in status." They are listed in 26 CFR 1.125-4.

The reason for the list is simple. A Section 125 cafeteria plan is a written employer plan that lets employees pay for benefits with pre-tax pay. To keep that tax treatment, elections must be made before the year starts and stay fixed unless a listed event happens.

Which events does the IRS allow?

The regulation groups the permitted events into several categories. The core list comes from 26 CFR 1.125-4 (eCFR, current).

The regulation also lists adoption assistance starting or ending as a status change.

Two points catch employers. First, cost changes for dependent care only count when the provider is not a relative. Second, the plan may pick which of these events to allow.

What is the consistency rule?

The consistency rule means the new election must correspond with and be triggered by the event. The event has to explain the change, per 26 CFR 1.125-4(c).

The IRS gives a clear example. If a dependent dies or loses eligibility, canceling coverage for other dependents fails the test. Only the coverage for the affected person can change.

A simple check for HR: ask "does this event explain this exact change?" If the answer is no, the request does not meet the rule.

Does a plan have to allow every mid-year change?

No. The regulation states that Section 125 does not require a cafeteria plan to permit any of these changes (26 CFR 1.125-4). Your written plan document decides which events count.

If the document allows an event, apply it the same way for every employee.

The two events added by IRS Notice 2014-55 need a document amendment before the plan can use them, per the notice. Read your Section 125 plan document→ before you say yes to a request.

What did IRS Notice 2014-55 add?

IRS Notice 2014-55 added two events for health coverage, effective September 18, 2014. Both are optional for the plan.

1. Reduction in hours. The employee moves from averaging at least 30 hours a week to averaging under 30 hours a week. This applies whether or not the change affects eligibility for the group health plan.
2. Marketplace enrollment. The employee is eligible for a Marketplace special enrollment period, or is enrolling during Marketplace open enrollment, and the new coverage starts no later than the day after the old coverage ends.

The plan may rely on the employee's statement that they plan to enroll in the new coverage. Revocations cannot be retroactive, per IRS Notice 2014-55.

These events help workers whose hours drop. They also connect the employer plan to the Marketplace. Employees who use it should read about the Marketplace side too, such as Summit's special enrollment period guide↗.

How do mid-year changes work for health FSAs and dependent care?

The same event list applies, but limits and risks differ. A health FSA has a 2026 salary reduction limit of $3,400, and the dependent care exclusion is $7,500 ($3,750 if married filing separately), per IRS Publication 15-B (2026).

Health FSAs are tricky because the plan covers the whole year from day one. Adding or raising an election mid-year must still follow the plan's rules. Check the 2026 FSA limits and rules→ before you approve a large change.

Dependent care follows the cost rule above. If a relative provides the care, a cost change alone does not qualify.

How should HR run a mid-year change request?

A written process protects both the employer and the employee. Use these steps.

1. Collect the request in writing, with the event and its date.
2. Ask for proof, such as a marriage certificate, birth record or coverage end letter.
3. Match the event to the plan document's list.
4. Apply the consistency rule to the exact change requested.
5. Set the new election's effective date, with no retroactive revocations.
6. Update payroll and keep the file.

Keep a log by event type. If an audit or a dispute happens, the log shows you treated employees the same way.

How do qualifying life events affect FICA savings?

Each pre-tax dollar an employee elects avoids 7.65% employer Social Security and Medicare tax, per IRS Publication 15 (2026). A mid-year change moves that amount up or down.

For example, if an employee adds a spouse and raises pre-tax premiums by $200 a month, employer FICA savings rise by about $15.30 a month ($200 x 7.65%). The employee also saves at least the same 7.65% in payroll tax.

The reverse is true when someone drops coverage. That is normal. The savings follow the elections.

Employers can also compare how another team explains the same rules on Summit's qualifying event page↗.
