    The ACA Marketplace in 2026-27: subsidies, premiums and enrollment

    The ACA Marketplace (HealthCare.gov and state exchanges) sells individual health plans, mostly with income-based premium tax credits. The enhanced credits expired at the end of 2025, so people above 400% of the poverty level again get no credit.[1][2] In 2026, average premium payments rose 58% and paid enrollment fell to 19.2 million. Insurers have proposed a median 15% increase for 2027.[3][4][5]

    The ACA Marketplace is where people without job-based coverage, Medicare or Medicaid can buy their own health insurance, usually with a federal tax credit that lowers the monthly premium.[6] The rules changed sharply in 2026, when temporary enhanced credits expired.[1] This explainer is the first stop in a short course on US health coverage in 2026-27. It is for information only and is not financial, tax or medical advice. A licensed navigator or tax adviser can help with your own situation.

    How the Marketplace works

    You apply on HealthCare.gov or your state’s exchange and report your expected income for the year. Your savings are based on that estimate, not on last year’s income.[7] Plans come in four metal levels, from Bronze to Platinum. The level tells you how costs are split between you and the plan when you get care. It says nothing about the quality of care.[8] Most people who sign up get a premium subsidy: 87% did in 2026.[9]

    Benchmark silver premiums, the basis for federal subsidies, rose 26% on average in 2026 once rates were finalized.[10] Under the enhanced credits that applied from 2021 to 2025, people above 400% of the federal poverty level (FPL) paid no more than 8.5% of income for the benchmark plan. Now that the credits have expired, that group gets no credit and pays the full premium.[2] Cost-sharing reductions, which lower deductibles and copays, are only available in silver plans.[11] The share of sign-ups receiving credits fell from 92% in 2025 to 87% in 2026, the first decline since 2020.[9]

    What changed in 2026

    When the enhanced credits ended, many people’s bills went up. The average premium payment after credits rose 58%, from $113 to $178 a month.[3] Many people switched to cheaper bronze plans, so average deductibles jumped to a record $3,786.[12] The number of people with paid coverage fell from 22.1 million in 2025 to 19.2 million in February 2026.[4]

    Open Enrollment sign-ups fell by about 1.2 million to 23.1 million.[13] Effectuated enrollment fell further, by 13%, once unpaid premiums were counted.[4] The administration attributes the decline to its anti-fraud work. KFF notes the decline coincided with steep increases in premium payments.[14]

    The political fight over the credits

    The Senate rejected both a Democratic-led three-year extension and a Republican health-account bill on 11 December 2025. Each got 51 votes, short of the 60 needed.[15] The House passed a three-year extension by 230-196 on 8 January 2026, with 17 Republicans voting yes.[16] Senate negotiators discussed shorter extensions with income caps and minimum premiums.[17] Republicans argued the credits were so generous that they let insurers charge more and encouraged improper or fraudulent enrollment.[18] In KFF polling, 67% of the public said Congress was wrong not to extend the credits, while 63% of Republicans said it was right.[19]

    Other rule changes

    The 2025 reconciliation law and new federal rules add more paperwork. Some people who enroll outside the usual window can no longer get financial help.[20] From 2028, new verification rules could effectively end automatic re-enrollment.[21]

    Since 2026, people who enroll through an income-based special enrollment period, and low-income immigrants who are ineligible for Medicaid because of their immigration status, cannot get Marketplace subsidies.[20] The reconciliation law requires full repayment of excess advance credits and bars many lawfully present immigrants from credits.[21] Many of the administration’s stricter verification rules are on hold because of litigation.[22] In September 2026, CMS cancelled about 315,000 enrollments covering more than 760,000 people that it described as unauthorized.[23] KFF said the process likely removed some people who were enrolled legitimately.[24] CMS also paused new agent and broker registrations for 2027.[25] The administration is promoting short-term plans, which can reject people for their medical history and do not qualify for credits.[26]

    2027: premiums and dates

    Insurers proposed a median 15% premium increase for 2027 across 276 filings. The 2026 median finalized increase was 20%.[5] They cite medical cost growth of 10% and a sicker risk pool, among other factors.[27][28] Open Enrollment on HealthCare.gov runs from 1 November 2026 to 15 January 2027.[29] The 2027 out-of-pocket limit is $12,000 for an individual.[30]

    Questions readers ask

    What happened to the enhanced ACA subsidies?

    The enhanced premium tax credits, created in 2021 and extended through 2025, expired on 31 December 2025. The House passed a three-year extension in January 2026, but as of October 2026 the credits had not been restored.[1][16][31]

    Can I get a premium tax credit if I earn more than 400% of the poverty level?

    Not since the enhanced credits expired. People above 400% of the federal poverty level pay the full, unsubsidized premium; under the enhanced credits their benchmark premium had been capped at 8.5% of income.[2]

    How many people have ACA Marketplace coverage in 2026?

    Federal data showed 19.2 million people with paid coverage in February 2026, down 13% from 22.1 million in 2025. Sign-ups during Open Enrollment were 23.1 million.[4][13]

    How much did ACA costs go up in 2026?

    Average monthly premium payments after tax credits rose 58%, from $113 to $178, and average deductibles rose 37% to a record $3,786.[3][12]

    When can I sign up for a 2027 Marketplace plan?

    On HealthCare.gov, from 1 November 2026 to 15 January 2027. Enroll by 15 December for coverage that starts on 1 January.[29]
