Center for Medicare & Medicaid Social Security Number Mandate
The Center for Medicare & Medicaid Services requires Employee Services to have a Social Security number on file for all medical and/or dental participants. To ensure your dependents are covered, you must provide this information.
If you are enrolling a newborn child, contact a benefits counselor to discuss how to do so in a timely matter, and also provide this necessary information to our office. If you wish to cover dependents on your benefits plans who are not eligible for a Social Security number, contact a benefits counselor for instructions on how to enroll your dependents.
Federal Tax Dependency for Health Coverage Purposes
If you are enrolling your same-gender domestic partner (SGDP) and/or your SGDP's children, you must identify whether they are qualified or non-qualified federal tax dependents for health coverage purposes. They are qualified federal tax dependents for health coverage purposes if they meet one of the following definitions:
A "qualifying child" is an individual who:
- is a child of the taxpayer; including an adopted child or an eligible foster child (one who is placed with the employee by an authorized placement agency or by judgment, decree, or other order of court) or a stepchild; and
- has the same principal place of residence as the taxpayer for more than one-half of the calendar year; and
- has not (other than in the case of total disability) yet reached age 19 by the end of the calendar year (age 24 if a full-time student for at least five months); and
- has not provided over one-half of such individual's own support for the calendar year.
A "qualifying relative" is an individual who:
- is not your qualifying child or the qualifying child of any other taxpayer; and
- is either related to you, or is a non-relative with the same principal place of abode for the year who is a member of your household; and
- who receives more than one-half of his or her support from you for the calendar year.
An adult child (unmarried, non-student age 19 or older) may be a qualified federal tax dependent for health coverage purposes if he or she meets the definition of a qualifying relative.
A same-gender domestic partner (SGDP) is not a qualified federal tax dependent for health coverage purposes unless he or she meets the definition of a qualifying relative. If your SGDP and your SGDP's children are qualified federal tax dependents for health coverage purposes, you must submit the SGDP Tax Certification of Dependency for Tax Treatment of Medical Benefits.
Your dependents are considered non-qualified federal tax dependents for health coverage purposes if they don't meet one of the above definitions. When enrolling a non-qualified, federal tax dependent for health coverage purposes in a university plan, there are tax consequences, referred to as imputed income, that will be calculated into your taxable income.
Qualified federal tax dependents for health coverage purposes may have claims submitted to the HealthCare Flexible Spending Account for reimbursement; non-qualified federal tax dependents for health coverage purposes may not.
If you do not indicate your SGDP and his/her children as qualified federal tax dependents for health coverage purposes, they will be considered non-qualified federal tax dependents for health coverage purposes, and you may incur imputed income. However, they will still be covered as long as eligibility documentation is provided.
NOTE: Employee Services is unable to assist you in making this determination. The employee must determine if the dependent meets the definition of a federal tax dependent for health coverage purposes. If you are uncertain, please consult a tax adviser.
Households with two university (or university affliate) employees and/or retirees
As an eligible participant in university benefit plans:
- You and your dependents cannot be covered as both an employee/retiree and a dependent for any university medical or dental plan.
- Two employee/retiree spouses/same-gender domestic partners (SGDPs) cannot enroll in medical and/or dental coverage for themselves and also be double covered as a dependent on their spouse's/partner's medical and/or dental plan.
- An employee may be insured as both an employee and a spouse/SGDP up to a maximum combined optional life insurance benefit of $500,000
- Each parent employee/retiree may enroll in different plans and may enroll different dependent children under his or her coverage.
- Both parent employee/retirees cannot enroll the same child for medical and/or dental plans.
- A dependent child may be insured by more than one employee for dependent optional life insurance.
