Enrolling for Coverage

What to Know

Exelixis is always proud to offer a great mix of benefits to support your physical, emotional, and financial well-being. Here’s everything you need to know to take full advantage of them.

What You Need to Do

New Hires

You have 30 days to enroll starting on the date you were hired. Benefits are effective on your hire date. Once you’ve reviewed the information on this site about your benefits and made your decisions, you can enroll using Workday through OneLogin.

If you don’t enroll within the 30-day period, you won’t have another chance to enroll until Open Enrollment in the fall of 2024 for benefits effective January 1, 2025, unless you have a qualified change in status.

Review the HIPAA Privacy Notices.

You and your dependents are eligible for health benefits if you work at least 30 hours per week.

Your eligible dependents include:

  • Your legal spouse
  • Your qualified domestic partner
  • Your children up to age 26, including your natural or adopted children, your stepchildren, and your qualified domestic partner’s children
  • Mentally or physically disabled children of any age, as long as they became disabled before age 19

Enrolling Your Domestic Partner

You may enroll your qualified domestic partner in medical, dental, vision, voluntary life, and voluntary AD&D coverage.

Your partner may qualify as a domestic partner if:

  • Neither you nor your partner is married or legally separated from any other person
  • You and your partner are each other’s sole domestic partner and intend to remain so indefinitely

Domestic partners can qualify for benefits coverage in one of two ways:

  • Register your domestic partnership as required by your state. You must also complete the Affirmation of the Existence of Registered Domestic Partnership section of the Affidavit of Domestic Partnership form.
  • Apply as non-registered partners. This is for individuals who choose not to register or who are not eligible to register their domestic partnership with their state. You must submit an Affidavit of Domestic Partnership form to the Human Resources department during enrollment.

Note: Domestic partners are not currently recognized as IRS dependents. Therefore, the portion of premiums your employer pays on behalf of your domestic partner must be taxed. This is called imputed income. Also, any premiums you pay that are attributable to the domestic partner coverage must be taxed. These premiums are deducted on a post-tax basis versus pretax. Please review the Domestic Partner Policy for more information. You can read more about the Exelixis Domestic Partner Policy and find forms.

Making Changes During the Year

Due to IRS regulations, once you’ve made your elections for the plan year, you cannot change your benefits until the next Open Enrollment period. The only exception is if you have a qualified change in status. Your status change will determine the benefit election changes you can make, when those changes take effect, and the deadline for applying to make the changes.

Examples of qualified status changes include:

  • Marriage, legal separation, or divorce
  • Birth or adoption of a child
  • Change in employment status for you or your spouse that results in gaining or losing coverage
  • Change in a dependent’s benefits eligibility status (e.g., a dependent child exceeds the maximum age for coverage)
  • Loss of a dependent (death)

If you have a qualified change in status and wish to change your benefits, you must request the change by logging in to your Workday account or by contacting Human Resources within 30 days of the life-event change. If you miss the 30-day window, you may not change your benefits until the next Open Enrollment.
