ACA Marketplace Health Insurance in Ohio
Ohio residents shop for marketplace health insurance through Healthcare.gov. Whether you live in Columbus, Cleveland, Cincinnati, Toledo, Akron, or a rural county, an independent broker can pull every plan available in your ZIP code at no cost. Open Enrollment runs November 1 through January 15, with coverage effective January 1 for enrollments completed by December 15.
Ohio expanded Medicaid under the ACA in January 2014. Residents earning below 138% FPL (~$21,597 for a single adult in 2026) may qualify for Ohio Medicaid rather than marketplace subsidies. An independent broker can help you determine the right pathway.
ACA Carriers Available in Ohio (2026)
Ohio has strong carrier competition in most metro areas, with several options available statewide and in key markets:
- Molina Healthcare — Available in many Ohio counties. Focuses on affordable coverage for lower-income households and Medicaid-adjacent populations.
- Medical Mutual of Ohio — Ohio-based carrier with broad statewide availability. Offers HMO and PPO-style plans.
- Ambetter (Celtic Insurance / Centene) — Competitively priced Silver plans in many Ohio counties. Strong option for subsidy-eligible buyers.
- CareSource — Nonprofit plan available in select Ohio markets, particularly in western Ohio.
- Oscar Health — Available in the Columbus and Cleveland metro areas with telehealth-forward plan design.
Carrier availability and premiums vary significantly by county. Rural Ohio counties often have fewer carrier options than metro areas.
Ohio-Specific Subsidy Notes
Because Ohio expanded Medicaid, residents above 138% FPL are the primary market for ACA subsidies. Premium tax credits apply from 138% FPL up through 400% FPL, with enhanced credits under the Inflation Reduction Act extending above that threshold. Ohio residents above 400% FPL may still receive subsidies if their benchmark Silver plan premium exceeds a set percentage of income.
Silver plan cost-sharing reductions (CSRs) are available for Ohio residents earning 138%–250% FPL when they select a Silver plan. CSRs can reduce deductibles and out-of-pocket maximums dramatically — often cutting a Silver deductible to $500 or less at 150% FPL.
Self-Employed in Ohio?
Self-employed Ohio residents — freelancers, LLC owners, sole proprietors, S-corp owners, and 1099 workers — can deduct 100% of health insurance premiums on Schedule 1 of Form 1040. This above-the-line deduction lowers adjusted gross income, which can reduce your tax liability and may improve subsidy eligibility.
