Domestic Partner Tax Implications

When you enroll your domestic partner or your partner’s child in one of the City’s health plans, the IRS considers the City’s contribution toward the additional coverage as income for federal tax purposes. This income is the amount the City contributes towards the cost of additional coverage for your domestic partner and/or your partner’s child. Any increase in your bi-weekly payroll deduction amount to cover your domestic partner and/or your partner’s child is also taxable.

The amount of this income depends upon the plan in which you are enrolled and the level of your coverage. This income increases your taxable gross income for federal income taxes and FICA (Social Security and Medicare). Taxes are withheld from your paycheck and will be reported on your annual W-2 form. More details are available in the Domestic Partner Enrollment Packet.

This monthly income must be added to your gross taxable income per IRS Code. Below is a simplified example of how this income is calculated. The City understands that this is a complex issue. Please consult your personal tax advisor for assistance.

Benefit elections made during Open Enrollment remain in effect for the entire year, January 1 through December 31. The IRS requires that your benefit elections remain in effect the entire calendar year, unless you experience a Qualifying Life Event. 

Qualifying Life Events may include: 

  • Marriage 
  • Establishment of a Certified Domestic Partnership 
  • Divorce, Legal Separation, Annulment, or Dissolution of a Domestic Partnership 
  • Birth or Adoption of an Eligible Child 
  • Change in your or your spouse’s/certified domestic partner's work status (full-time or part-time) that affects benefits eligibility 
  • Change in your child’s eligibility for benefits 
  • Qualified Medical Child Support Order 
  • Death of a dependent 

You must notify the Employee Benefits Office within 31 calendar days of your Qualifying Life Event and provide all required documentation in order for the changes in your coverage to take effect during the calendar year. If you fail to notify the Employee Benefits Office (210.207.0073) within 31 calendar days and do not provide all required documentation, you must wait until the next Open Enrollment period to change your benefit elections.
