2026 Open Enrollment Dates

The federal marketplace (HealthCare.gov) open enrollment period for 2026 plan year coverage runs from November 1, 2025 through January 15, 2026. Some states with their own marketplaces have extended deadlines. For coverage starting January 1, 2026, enroll by December 15, 2025. Enrolling after that date means coverage starts February 1.

Special Enrollment Periods

Outside open enrollment, you can enroll or change plans if you experience a qualifying life event: losing employer coverage, getting married or divorced, having a baby, moving to a new area, or losing Medicaid eligibility. You have 60 days from the event to enroll. Some states offer additional SEP triggers.

Understanding Premium Subsidies

The Inflation Reduction Act extended enhanced premium subsidies through 2025, with Congress considering further extensions. Subsidies are based on your household income relative to the federal poverty level. A family of four earning $60,000 might qualify for $800+/month in subsidies, making silver plans very affordable.

Choosing the Right Metal Tier

Bronze plans: lowest premiums, highest out-of-pocket costs — best for healthy individuals who rarely use care. Silver plans: moderate premiums and costs, plus extra savings for lower incomes (CSR). Gold plans: higher premiums but lower copays — best for frequent medical users. Platinum plans: highest premiums, lowest costs per visit.

Comparing Plans Beyond Price

Don't just look at monthly premiums. Calculate total annual cost: premiums + expected deductible + copays for your typical usage. Check that your doctors and medications are covered. Review the formulary for prescription drug tiers. A cheaper plan that doesn't cover your specialist or medication costs more overall.

HSA-Eligible Plans

High-deductible health plans (HDHPs) paired with Health Savings Accounts (HSAs) offer triple tax advantages: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. In 2026, individuals can contribute up to $4,300 and families up to $8,550. If you're generally healthy, this combo can save thousands.

Common Enrollment Mistakes

Don't auto-renew without comparing — plans change every year. Don't underestimate your income (you'll owe back subsidies). Don't choose the cheapest plan without checking networks. Don't wait until the last day — system congestion causes errors. Start comparing plans 2 weeks before the deadline. Use MaboRates to compare health plans side by side.
