You are eligible for the benefits described on this site if you are an active full-time or part-time employee of the Company in the U.S., scheduled to work at least 24 hours per week. In addition to yourself, you can cover eligible dependents under the medical, dental, vision, group life and AD&D plans, and voluntary benefits. Dependent verification is required.
Reminder for SpringWorks Employees
The Company medical, dental, and vision plans cover eligible dependents until they reach age 26. If you have a dependent age 26 or older, they will not be eligible for Company coverage in 2027. Review important enrollment information in this Transition Flyer.
1 If you cover a domestic partner (or his/her child[ren]), special tax rules apply. See the Domestic Partner tab for details.
Social Security Numbers
You will not be able to complete the enrollment process until you have filled in the Social Security number field for all covered dependents, due to requirements under the Affordable Care Act (ACA). The only exception to this requirement is for children up to six months of age. They will be accepted without a Social Security number.
If you need assistance updating a Social Security number, contact the Benefits4Me Program Service Center at 1-844-279-7894. Representatives are available Monday through Friday, 9:00 a.m. to 6:00 p.m. ET.

Tax Implications of Domestic Partner Coverage
If you cover your domestic partner (and/or their children), federal law requires the Company to treat the value of their benefits differently for tax purposes. This may affect you in three ways:
Be sure that you enroll only dependents who meet the plan’s eligibility requirements.
When adding a new dependent to your coverage, you will be required to provide supporting documentation showing proof of your relationship, within 30 days of enrolling your dependent.
Dependents are not added to your coverage until the required documentation is received by our benefits administrator, Benefits4MeEnroll, so it is imperative that you provide documents within 30 days.
Once documentation is received, reviewed, and approved, dependents are added to your coverage retroactive to the coverage start date for which they have been enrolled.
Please note: Documentation in languages other than English or Spanish require notarized translations.
Note: The Company will be conducting a dependent eligibility audit in early 2027 to ensure all the dependents enrolled in Company healthcare coverage are eligible, as defined by the plan.
