Your real deadlines — no red countdown

Turning 26 and coming off a parent's plan

Use the dependent coverage end date—not the birthday alone—to map the Marketplace window and proof to keep.

MedicalRecords.com Editorial · reviewed August 11, 2026

The facts to establish first

Potential trigger: Aging off a parent's plan can trigger a Marketplace Special Enrollment Period when dependent coverage actually ends.
First action: Ask the plan for the exact dependent coverage-end date; it may not be the birthday itself.
Proof to keep: Keep a coverage letter or eligibility notice that names the dependent and the final day of coverage.

Verify timing with HealthCare.gov's Special Enrollment Period guidance and, when continuation coverage applies, the U.S. Department of Labor COBRA guide. Rules depend on the event and notice; the calculator below does not replace the official eligibility result.

Start with what happened

The tool calculates the federal loss-of-coverage window and, when the notice date is known, the COBRA election deadline. It does not estimate subsidy dollars without the ZIP, ages, income rules, and live Marketplace data needed to do that responsibly.
