What Is a Benefit Year?
A benefit year (or plan year) is the 12-month period during which your health insurance benefits are active. For most individual and marketplace plans, this runs January 1 through December 31. Employer plans may use a different start date (e.g., July 1 to June 30).
What Resets at the Start of a New Benefit Year
- Deductible: Goes back to $0 — you start over
- Out-of-pocket maximum: Resets — even if you hit the cap last year
- Copay and coinsurance accumulation: Starts fresh
December strategy: If you've already met your deductible for the year, schedule any elective procedures, imaging, or specialist visits before December 31. Once January 1 hits, you're paying full price again until your new deductible is met. This applies to both marketplace and private plans.
Mid-Year Enrollment
If you enroll mid-year through a Special Enrollment Period, your benefit year still ends December 31. Your deductible and out-of-pocket maximum are not prorated — they're the same whether you enroll in January or October.
