Adding spouse to insurance

Marriage is a qualifying life event (QLE) that triggers a Special Enrollment Period (SEP), allowing you to add your spouse to your health insurance or switch to your spouse's plan outside of the regular open enrollment window. You typically have 30-60 days from the date of marriage to make changes.

1. Steps Process

  • Understand Your Options
  • Option A: Add your spouse to your employer plan
  • Option B: Join your spouse's employer plan
  • Option C: Each spouse keeps their own employer plan
  • Option D: One or both enroll in an ACA Marketplace plan
  • Compare coverage, premiums, deductibles, copays, out-of-pocket maximums, and provider networks for each option
  • Notify Your Employer / HR Department
  • Inform HR within 30 days of the marriage (most employer plans enforce this deadline strictly)
  • Ask for the Special Enrollment Period forms and instructions
  • Request plan documents to compare coverage options and costs

2. Key Details

  • Qualifying event window: 30-60 days from marriage date (check your specific plan)
  • Coverage start date: Typically the first of the month following enrollment; some plans backdate to the marriage date
  • Premium impact: Adding a spouse increases premiums; compare the cost vs. keeping separate plans
  • Missing the deadline: If you miss the 30-60 day window, you must wait until the next open enrollment period (usually in November/December for January coverage)
  • Marketplace plans: Report the marriage through Healthcare.gov or your state exchange within 60 days
  • COBRA: If your spouse is on COBRA, marriage provides them an opportunity to switch to your employer plan
