Qualifying Life Events and Special Enrollment Periods Explained

Last updated: May 2026

Outside of the annual open enrollment window, you generally cannot enroll in or switch health plans unless you experience a qualifying life event (QLE). A QLE opens a limited special enrollment period (SEP) during which you can make changes to your coverage.

Key takeaways

A qualifying life event (QLE) opens a special enrollment period (SEP) during which you can change health plans outside of open enrollment.
On the ACA Marketplace, the special enrollment period is typically 60 days, either before or after the event.
For employer plans, the window is usually 30 days from the event under Section 125 rules, though HIPAA special enrollment events often allow up to 60 days.
Common QLEs include loss of coverage, marriage or divorce, birth or adoption, permanent move, and gaining citizenship or new immigration status.

What is a qualifying life event?

A qualifying life event is a specific life or household change that the federal government and your plan recognize as a reason to allow mid-year enrollment. The same QLE that lets you enroll on the ACA Marketplace generally lets you change or enroll in your employer's plan, but the timelines and required documentation differ.

How long is a special enrollment period?

The window depends on which type of plan you are enrolling in:

ACA Marketplace: typically 60 days from the date of the qualifying event. Some events (like a known upcoming loss of coverage) allow enrollment in the 60 days before the event to prevent a coverage gap.
Employer plans (Section 125): typically 30 days from the qualifying event. The exact window is set in the plan's cafeteria plan document.
HIPAA special enrollment events (such as loss of other group coverage or gaining a dependent): generally a 30-day window for employer plans, extended to 60 days when the loss of coverage is due to loss of Medicaid or CHIP eligibility.

If you miss the SEP window, you typically have to wait until the next open enrollment period to change plans, even if you no longer have coverage.

What life events qualify?

The federal government groups QLEs into four broad categories:

Loss of qualifying health coverage

Job loss, reduction in hours, or end of COBRA coverage
Aging off a parent's plan at 26
Loss of eligibility for Medicaid or CHIP
Loss of student health coverage

Changes in household

Marriage
Birth, adoption, or placement of a child in foster care
Divorce or legal separation (if it results in loss of coverage)
Death of a household member

Changes in residence

Moving to a new ZIP code or county
Moving to or from a shelter or transitional housing
A student moving to or from school
A seasonal worker moving to or from where they live and work

Other qualifying changes

Gaining U.S. citizenship or lawful immigration status
Leaving incarceration
Starting or ending AmeriCorps VISTA service
A court order requires you to provide coverage to a child or dependent
Becoming a survivor of domestic abuse or spousal abandonment

Some additional events that qualify on a case-by-case basis include a serious Marketplace error in your enrollment, a FEMA-designated natural disaster that prevented timely enrollment, and certain plan-specific events. Healthcare.gov publishes a complete list of recognized SEPs.

What is not a qualifying life event?

Plans are explicit about what does not qualify. Common non-events that surprise people:

A new diagnosis, illness, or surgery
Voluntarily dropping other coverage (you must lose it involuntarily)
Failing to pay premiums on your prior plan
Pregnancy alone (on the federal Marketplace; some state marketplaces differ)
Plan renewals or premium increases at your current employer

How do I enroll using a special enrollment period?

The process depends on the type of plan:

Employer plan: contact your HR or benefits administrator within the plan's SEP window. They will ask for documentation such as a marriage certificate, birth certificate, or prior coverage termination letter.
ACA Marketplace: log in to your account on Healthcare.gov or your state marketplace, complete the QLE attestation, and upload supporting documents. Coverage typically starts on the first of the month after enrollment, with exceptions for birth and adoption (immediate) and some loss-of-coverage events.
Spouse's employer plan: contact their HR within their plan's SEP window. This is often the cheapest option when available.

Example: a new job mid-year

You start a new job in July. Starting employment is a qualifying life event for your new employer's plan, which typically gives you a 30-day window to enroll. The end of your old employer's coverage is also a separate qualifying event, which opens a 60-day Marketplace special enrollment period and may qualify your spouse to add you to their plan. You can compare all available options before deciding.

Example: a child is born

You have 30 days to add a newborn to your employer plan (60 days on the Marketplace). Coverage is effective from the date of birth if you enroll within the window. After the window closes, you generally have to wait until the next open enrollment to add the child.

Compare plans before you enroll

A qualifying life event often gives you multiple options: a new employer plan, a spouse's plan, a Marketplace plan, or COBRA. Use the Health Plan Compare calculator to model total annual cost for each option using your expected care usage.

FAQ

What is a qualifying life event?

A qualifying life event (QLE) is a change in your life or household that allows you to enroll in or change a health plan outside of the normal open enrollment period. Common examples include marriage, divorce, the birth or adoption of a child, loss of other health coverage, and a permanent move to a new area.

How long is a special enrollment period?

On the ACA Marketplace, a special enrollment period generally lasts 60 days, either before or after the qualifying event depending on the event type. For employer plans operating under a Section 125 cafeteria plan, the window is typically 30 days from the event, though HIPAA special enrollment events (such as loss of other coverage) often allow up to 60 days.

Does loss of a job count as a qualifying life event?

Yes. Loss of employer-sponsored health coverage due to job loss, reduction in hours, or end of COBRA is a qualifying life event for the ACA Marketplace (60-day window) and typically qualifies you to enroll in a spouse's employer plan as well.

Does pregnancy count as a qualifying life event?

Pregnancy by itself is not a qualifying life event on the ACA Marketplace. However, the birth of a child is. After delivery, you have 60 days to add the newborn to a Marketplace plan or enroll in a new plan. Some states with their own marketplaces (such as New York) treat pregnancy as a qualifying event.

Does turning 26 count as a qualifying life event?

Yes. Losing coverage under a parent's health plan when you turn 26 is a qualifying life event. You have 60 days from the loss-of-coverage date to enroll in a Marketplace plan, your own employer plan, or other coverage.

Can I enroll in a Marketplace plan before the qualifying event happens?

For some events, yes. If you know you will lose coverage in the next 60 days (for example, an upcoming job change or a child turning 26), you can apply for a Marketplace plan in advance to avoid a coverage gap. Other events, such as marriage or birth, must already have occurred.

What documentation do I need to prove a qualifying life event?

The Marketplace and employer plans typically require documentation such as a marriage certificate, birth certificate, divorce decree, prior coverage letter, lease agreement (for a move), or termination letter from the employer. Submit the documentation promptly to avoid delays in coverage.
