The Affordable Care Act

The Affordable Care Act (ACA), commonly known as “Obamacare,” continues to provide Americans with access to affordable health insurance through the Health Insurance Marketplace. In 2025, the ACA remains a vital resource for individuals and families seeking comprehensive health coverage.

How the ACA Works in 2025

Health Insurance Marketplace

The ACA established the Health Insurance Marketplace, an online platform where individuals can compare and purchase health insurance plans. These plans are categorized into four metal tiers—Bronze, Silver, Gold, and Platinum—based on the cost-sharing structure between the insurer and the insured.

Essential Health Benefits

All ACA-compliant plans are required to cover a set of essential health benefits, including:

• Ambulatory patient services

• Emergency services

• Hospitalization

• Maternity and newborn care

• Mental health and substance use disorder services

• Prescription drugs

• Rehabilitative and habilitative services

• Laboratory services

• Preventive and wellness services

• Pediatric services, including oral and vision care

Financial Assistance

To make coverage more affordable, the ACA provides financial assistance to eligible individuals and families:

• Premium Tax Credits: These credits lower monthly premium costs for those with incomes between 100% and 400% of the federal poverty level (FPL).

• Cost-Sharing Reductions: Available to individuals with incomes between 100% and 250% of the FPL, these reductions lower out-of-pocket costs like deductibles and copayments.

In 2025, enhanced premium tax credits established by the American Rescue Plan and extended by the Inflation Reduction Act continue to provide additional savings, ensuring that no one pays more than 8.5% of their income on premiums.

2025 Open Enrollment Timeline

Open Enrollment is the annual period when individuals can enroll in or make changes to their health insurance plans through the Marketplace. For 2025 coverage, the Open Enrollment period is as follows:

• November 1, 2024: Open Enrollment begins.

• December 15, 2024: Last day to enroll for coverage starting January 1, 2025.

• January 15, 2025: Open Enrollment ends. This is the final day to enroll for 2025 coverage. 

If you enroll between December 16, 2024, and January 15, 2025, your coverage will begin on February 1, 2025. 

Special Enrollment Periods

Outside of Open Enrollment, you may qualify for a Special Enrollment Period (SEP) if you experience certain life events, such as:

• Loss of health coverage

• Marriage or divorce

• Birth or adoption of a child

• Relocation

• Changes in income

SEPs typically allow you 60 days from the date of the qualifying event to enroll in a health plan.
