Employee Eligibility & Enrollment

This is the “Employee Eligibility & Enrollment” section of the Employee Benefits FAQ Library.

Employers establish eligibility waiting periods that determine when new hires can enroll in benefits. Common waiting periods include:

  • First of the month following hire
  • 30 days after hire
  • 60 days after hire
  • 90 days after hire

Under federal law, eligibility waiting periods generally cannot exceed 90 days for most employer-sponsored health plans.

Open enrollment is the annual period when employees can enroll in benefits or make changes to their existing coverage. During open enrollment, employees may:

  • Select a new health plan
  • Add or remove dependents
  • Enroll in voluntary benefits
  • Adjust benefit elections

Once the open enrollment period closes, changes are generally limited until the next plan year unless a qualifying life event occurs.

A qualifying life event allows employees to make changes to their benefits outside of the open enrollment period. These events typically involve major life changes.

Common qualifying life events include:

  • Marriage
  • Divorce
  • Birth or adoption of a child
  • Loss of other coverage
  • Death of a dependent

Employers must allow employees to update benefits following these events within the specified reporting window.

Employees typically have 30 to 60 days from the date of the event to report a qualifying life event and request benefit changes. If the event is not reported within the required timeframe, employees may need to wait until the next open enrollment period to make changes.

Employers often require documentation, such as a marriage certificate or birth certificate, to process the request.

Yes. Employees may decline employer-sponsored health insurance if they have other qualifying coverage, such as coverage through a spouse’s employer or another health plan.

Employees who waive coverage may be asked to provide proof of alternative coverage depending on employer policy.

Most employer-sponsored health plans allow employees to enroll dependents, which may include:

  • Spouses
  • Domestic partners (depending on plan rules)
  • Dependent children

Eligibility rules vary slightly between carriers and employers, so it is important to review plan documents for specific requirements.

Under the Affordable Care Act, dependent children can remain on a parent’s health insurance plan until age 26, regardless of whether the child:

  • Is married
  • Lives with the parent
  • Is financially dependent
  • Is a student

This rule applies to most employer-sponsored group health plans.

If an employee misses the enrollment deadline, they may have to wait until the next open enrollment period to enroll in benefits. The primary exception occurs if the employee experiences a qualifying life event that allows mid-year enrollment.

Employers typically communicate enrollment deadlines clearly to ensure employees have sufficient time to make benefit elections.

In most cases, employees can only change benefit elections during open enrollment. However, changes may be allowed mid-year following a qualifying life event such as marriage, birth, or loss of other coverage.

Changes must generally be consistent with the qualifying event.

Some employers choose to offer benefits to part-time employees, though it is not always required. Eligibility rules vary depending on employer policy and insurance carrier guidelines.

Offering benefits to part-time employees may help employers attract and retain workers in competitive labor markets.
