Cheapest ACA plans in Maine for 2026

Cheapest plans by metal tier

Lowest 2026 monthly premium for a single 40-year-old non-tobacco user, on-exchange, before any subsidy. Per-age figures derived from the CMS QHP Landscape file using the HHS standardized age-rating curve (45 CFR 147.102).

The actual cheapest plan in major counties

Same data the search returns: carrier, plan name, monthly premium, individual deductible, individual MOOP. Computed for a single 40-year-old non-tobacco user, before any subsidy. Catastrophic plans excluded because adults 30+ typically need a hardship-exemption certificate to enroll.

The actual cheapest plan for a family of four

Two 40-year-old adults and two kids in the 0-14 age band, before any subsidy. Carrier, plan name, premium, deductible, and MOOP exactly as the search would return them.

Subsidies: federal APTC plus §1332 reinsurance (MGARA)

Maine does not fund a state premium subsidy but operates a §1332 reinsurance waiver that lowers on-exchange premiums for all enrollees. Marketplace help is:

1. Federal Advance Premium Tax Credit (APTC). Households 100-400% FPL on the PY2026 standard ACA contribution curve, applied through CoverME.gov. The ARPA / IRA enhanced subsidies expired 2025-12-31 and are not in effect for 2026.
2. Federal cost-sharing reductions (CSRs). Households 100-250% FPL enrolled in a Silver plan receive reduced deductibles, copays, and out-of-pocket maximums automatically.
3. Maine Guaranteed Access Reinsurance Association (MGARA). Maine’s §1332 waiver program reinsures high-cost claims in the individual market. The waiver was originally approved in 2012, dormant under the ACA after 2014, and reactivated effective PY2022. MGARA reduces gross premiums on CoverME.gov for all enrollees, not only those who receive APTC.

Maine expanded Medicaid (MaineCare) effective January 2019, implementing Question 1 (the 2017 voter-approved ballot initiative). Adults 19-64 up to 138% FPL qualify, so there is no coverage gap in Maine.

Catastrophic plans in Maine follow federal rules

Maine follows the federal ACA default: Catastrophic plans are available to enrollees under age 30, or at any age with a hardship / affordability exemption. The PY2026 federal auto-expansion applies: adults 30+ automatically qualify when the lowest-cost Bronze plan exceeds the affordability threshold. APTC does not apply to Catastrophic plans.

Tobacco surcharges follow the federal 1.5x default in Maine

Maine applies the federal ACA default (45 CFR 147.102): carriers may charge tobacco users up to 50% more than non-users (a 1.5-to-1 rate ratio). The Maine Bureau of Insurance reviews rate filings under 24-A M.R.S. No Maine-specific cap below the federal 1.5x ceiling has been identified. Federal APTC does not offset the tobacco portion of the premium.

4 carriers, 1,600 plans across 16 counties. 774 sold on CoverME.gov, 826 off-exchange-only direct from carriers. Anthem Blue Cross Blue Shield is the dominant statewide carrier.
