- Where and when. Washington runs its own marketplace, Washington Healthplanfinder, so you apply there rather than at HealthCare.gov. Washington Healthplanfinder sets its own open-enrollment dates. We couldn't confirm the 2027 dates on an official page when we checked in September 2026, so check its site before you move.
- Choice of insurers. 8 insurers sell Marketplace plans in Washington for 2026, up from 7 in 2025. Not every insurer sells in every county, so your choices depend on where you live. 290,109 people picked a Marketplace plan here for 2026, down 6% from 2025.
- What enrollees paid. Enrollees here paid an average of $343 a month after tax credits for 2026, up 19% from the $288 they paid for 2025 (U.S. average: $178). Before credits, the plans they chose averaged $738.
- Medicaid. Washington expanded Medicaid in January 2014, when the ACA expansion took effect. Adults with income up to 138% of the federal poverty level can generally get Medicaid instead of a Marketplace plan.
- Going uninsured. Washington doesn't charge a penalty for going without coverage, and the federal penalty ended after 2018. In 2024, 6.5% of residents had no health insurance (U.S.: 8.2%), and 5% bought their own coverage.
Subsidies in 2026
The enhanced premium tax credits of 2021–2025 expired, so 2026 follows the original ACA rules: credits are available for household incomes between 100% and 400% of the federal poverty level, and you're expected to pay between about 2.1% and 9.96% of income for the benchmark plan. Above 400% there's no federal credit. Check your price at Washington Healthplanfinder.
