Frequently asked questions

What is the cheapest ACA plan in Williamson County, Texas for 2026?

The cheapest Bronze plan a 40-year-old can enroll in is Sendero Health Plans, Local Nonprofit Sendero Health Quality Care Bronze High Deductible / $50 PCP / $25 Generic Drugs / $100 Specialist at $433 per month before subsidies. Plans sell through Healthcare.gov. Data refreshed 2026-04-19T08:08:55.462Z.

Where do Texans buy ACA plans for 2026?

Texas uses the federal Marketplace at HealthCare.gov. Texas does not run a state-based exchange, so all PY2026 enrollment, subsidy eligibility, and plan changes go through HealthCare.gov. Open Enrollment runs November 1, 2025 through January 15, 2026, with December 15 as the deadline for January 1 coverage.

Does Texas offer any state premium help on top of federal APTC?

No. Texas has no state-funded premium subsidy, cost-sharing assistance program, or state reinsurance program. Texans rely on the federal advance premium tax credit through HealthCare.gov; about 92% of PY2026 Texas enrollees qualify for APTC, averaging roughly $667 per month in federal help.

What happens if my income is below the poverty line in Texas?

Texas has not expanded Medicaid, which creates a coverage gap. Non-disabled childless adults under 65 generally cannot qualify for Texas Medicaid at any income level, and federal Marketplace subsidies on HealthCare.gov only begin at 100% FPL. Roughly 570,000+ Texas adults fall into this gap. Check categorical Medicaid pathways (pregnancy, disability, dependent children), CHIP, and community health-center sliding-scale options.
