1. Premiums might get much pricier

How it works now: Premium tax credits help taxpayers afford marketplace health insurance premiums. Since 2021, “enhanced” premium tax credits have been larger and available to more people.

In states using HealthCare.gov, enhanced tax credits made subsidized premiums about $624 less expensive per year in 2024. That’s according to estimates by KFF, a health policy nonprofit.

Enhanced subsidies are set to expire after 2025. Smaller tax credits — and therefore more expensive premiums — go back into effect starting in 2026.
