Open Enrollment 2027 in Wyoming
Wyoming sells its plans through HealthCare.gov. Open Enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027; a plan picked by December 15 starts January 1.

The 2027 Tax-Credit Line in Wyoming
For 2027 coverage the premium tax credit stops at 400% of the poverty line: $63,840 of income for one person, $132,000 for a family of four. Below it the benchmark Silver plan costs no more than 10.22% of income; above it the prices in the tables are the prices. Gold costing less than Silver in 23 of 23 counties is the marketplace’s silver-loading at work: insurers price Silver for the cost-sharing help it carries, so a full-price buyer should look at Gold first, and a Bronze plan is HSA-qualified since 2026 (IRS Notice 2026-05).

Moving to Wyoming
A plan from another state does not move with you; a new Wyoming address opens a 60-day window. Moving to Wyoming: health insurance after the move has the dates, the marketplace and where Wyoming’s newcomers come from.
