ACA Health Insurance 2027 Enrollment Dates and How to Apply =========================================================== 2027 HealthCare.gov open enrollment runs through January 15, 2027 (U.S.). Check the separate deadline for January coverage, state schedules, what you need to enroll and subsidy eligibility. - Check enrollment requirements and deadlines for each coverage start date on your state's official marketplace. - Prepare information on your household members, expected 2027 income, immigration status and current insurance. - Apply through the official online portal or by phone and check your subsidy eligibility results. - Compare premiums, out-of-pocket medical costs, and coverage for hospitals and prescription drugs to choose a plan. - Pay your first premium by the deadline your insurer specifies and confirm that your coverage has started. You can apply for ACA health insurance if you meet enrollment requirements, such as living in the United States. The HealthCare.gov application deadline for coverage starting in January 2027 is December 15, 2026 (U.S.). Prepare your income and immigration status documents and choose a plan. You also need to pay your first premium. The enrollment schedule is based on the CMS announcement of October 30, 2026, and state notices. Steps to Apply for ACA Health Insurance Apply through your state’s official channel, then choose an insurance plan. The ACA Marketplace is an enrollment portal for comparing individual and family health insurance. It also assesses eligibility for premium assistance based on income and other factors. Check which Marketplace your state uses and its enrollment deadline. Prepare information about your household, expected income, immigration status, and existing insurance. Submit an application online or by phone. Check your application results for subsidy eligibility. Check the hospitals you plan to use and your prescription drugs, then choose a plan. Pay your first premium according to the insurer’s instructions. Also confirm that the payment has been processed and check your coverage start date. As of November 9, 2026, open enrollment is underway. Current enrollees can also renew or change plans during this period. Coverage will not begin if you do not pay your first premium. This condition is stated in HealthCare.gov’s first premium payment guidance. Enrollment Deadlines by Coverage Start Date On HealthCare.gov, you must complete enrollment in time for your desired coverage start date. If you wait until the final deadline, you cannot get January coverage. The dates below are those provided by official U.S. enrollment channels. Period for completing HealthCare.gov enrollment or plan changes Coverage start date Additional condition November 1 to December 15, 2026 January 1, 2027 Pay the first premium by the insurer’s deadline December 16, 2026, to January 15, 2027 February 1, 2027 Pay the first premium by the insurer’s deadline HealthCare.gov’s “When can you get health insurance?” provides the following guidance. December 15: Last day to enroll in or change plans for coverage to start January 1. This is the plan selection deadline for January coverage. Check your insurer’s instructions for the first premium payment deadline. Do not assume that completing the application means you have finished selecting a plan. Comparison of State Enrollment Periods State-based Marketplaces may have different schedules from the federal exchange. New York’s final deadline is January 31, 2027 (U.S.). California’s application deadline for January coverage also differs from the federal deadline. Official enrollment channel Open enrollment period for 2027 Guidance for coverage starting January 1, 2027 HealthCare.gov November 1, 2026, to January 15, 2027 Enroll by December 15, 2026 NY State of Health November 1, 2026, to January 31, 2027 The state Department of Health advises enrolling by December 15, 2026 Covered California November 1, 2026, to January 31, 2027 Enroll by December 31, 2026 New York’s schedule is based on the state Department of Health’s announcement of October 28, 2026. California’s schedule is based on Covered California’s enrollment guidance. (Verified dates: November 1, 2026, to January 31, 2027; enrollment deadline for January coverage: December 31, 2026 · Source: coveredca.com · As of 2026-11-05 · Checked on 2026-11-09) If you live in another state, check that state’s official enrollment channel. You must also confirm the deadline’s exact time and applicable time zone through that channel. Enrollment and Subsidy Eligibility Check insurance enrollment requirements and premium subsidy requirements separately. You may be eligible to enroll but not receive assistance. People enrolled in Medicare cannot enroll in Marketplace health insurance. Basic Enrollment Requirements HealthCare.gov lists the following requirements. You must live in the United States. You must be a U.S. citizen, U.S. national, or lawfully present noncitizen eligible to enroll. You must not be incarcerated. U.S. national status also includes a legal status distinct from citizenship. Noncitizens should check the official list of immigration statuses. Subsidy eligibility also depends on income, access to other insurance, and other factors. Subsidy Requirements by Immigration Status for 2027 Starting January 1, 2027, eligibility for federal assistance will be restricted for noncitizens. HealthCare.gov lists the statuses below as eligible for assessment for assistance. Even if you hold one of these statuses, you must meet the other assistance requirements. Status or situation What to check Lawful permanent resident, LPR, or Green Card holder Assistance may be available if you meet income and other requirements Cuban or Haitian entrant Confirm whether you have the entrant status defined by law Migrant under the Compact of Free Association, COFA Check your status and other assistance requirements Other lawful immigration status, such as a work or student visa Check insurance enrollment eligibility and federal subsidy restrictions separately Cuban or Haitian nationality alone does not establish the relevant entrant status. It is also inaccurate to say that only lawful permanent residents are eligible for assistance. Check which immigration status was applied in your application results. Information to Prepare Before Applying First, gather details about your household and expected income for 2027. Use HealthCare.gov’s “My Marketplace Application Checklist” as your preparation guide. Required documents vary depending on who is applying. Item to prepare Information to check Basic applicant information Name, date of birth, address, family relationships Household composition Spouse, tax dependents, and other household members Social Security Number Numbers for household members requested on the application screen Immigration documents Proof of the relevant immigration status for noncitizens Income information Income from wages, self-employment, and other sources, and expected household income for 2027 Existing insurance information Information about current insurance and insurance offered through work Contact information Email address, mailing address, and phone number for receiving notices Subsidy assessments use your expected income for the coverage year. First check whether it is appropriate to enter the previous year’s income unchanged. If you are asked for additional proof, check the submission deadline in the notice. Official Application Channels and Korean-Language Help HealthCare.gov offers online, phone, and local enrollment assistance. If your area uses a state-based exchange, apply through that state’s channel. You can use the options linked from the official application instructions. Application method How to use it HealthCare.gov online Sign in with an existing account or create an account Phone application Call 1-800-318-2596 Korean interpretation Request a Korean interpreter at the same phone number Local enrollment assistance Search Find Local Help by ZIP code or city and state State-based exchange Use NY State of Health, Covered California, or another state exchange HealthCare.gov provides free Korean-language help. Check with each local assistance organization about available languages and consultation methods. If you cannot access your existing account, use account recovery. Comparing Premiums and Plans Compare your actual costs for 2027 after subsidies are applied. Reports of premium increases alone cannot tell you how much you will pay. The result depends on where you live, your plan, and your eligibility for assistance. Covered California has explained the factors driving cost increases in 2027. It has also explained how expanded state assistance can ease those costs. This is a California example, and the same conditions do not apply nationwide. Comparison item What to check Monthly premium The amount you will pay after subsidies are applied Deductible The amount you pay first for certain covered services Out-of-pocket costs for care A fixed copayment or a percentage of the cost Annual out-of-pocket maximum The annual limit on what you pay for covered care Provider network Whether the doctors and hospitals you plan to use are under contract Prescription drug coverage Whether your medications are covered and what you will pay Insurer participation Whether your current insurer will sell plans in your area in 2027 The Silver category does not indicate the quality of care. It indicates how costs are shared between the insurer and the enrollee. Additional income-based cost-sharing reductions apply to Silver plans. If your eligibility results show additional reductions, factor them into your comparison. New York’s announcement includes Oscar Health’s withdrawal from the exchange in 2027. Covered California also notes Molina Healthcare’s withdrawal from some areas. If you want to keep your existing insurance, check the renewal notice for your area. Out-of-Pocket Maximums for 2027 HealthCare.gov lists the 2027 individual maximum as $12,000 per year. It lists the family maximum as $24,000 per year. Your actual plan or eligibility for cost-sharing reductions may result in a lower limit. Coverage year Annual individual maximum Annual family maximum 2026 $10,600 $21,200 2027 $12,000 $24,000 These limits apply to covered in-network care. Monthly premiums and costs for services that are not covered are not included. Out-of-network care costs do not count toward the same limit either. Check the scope of coverage in the Summary of Benefits and Coverage for the plan you choose. Checking for Coverage Gaps by Situation Compare the end date of your current insurance with the start date of your new insurance. The examples below apply the official coverage start dates to different situations. They assume you pay the new insurance’s first premium by the deadline. Situation Result to check Complete enrollment through the federal exchange by December 15 Eligible for coverage starting January 1, 2027 Enroll through the federal exchange during open enrollment on or after December 16 Eligible for coverage starting February 1, 2027 Current insurance ends December 31, 2026, and new insurance starts February 1 A coverage gap occurs in January 2027 if there is no other coverage Enroll in California by December 31, 2026 Eligible for coverage starting January 1, 2027, under state guidance A coverage gap can occur even before the final enrollment deadline. First check when your current insurance ends. You can also ask whether losing your insurance makes you eligible for special enrollment. What to Do If Your Income Changes After Applying Update your application information if your income or household composition changes. This is especially important if you receive advance premium tax credits. If you use more assistance than you are actually eligible for, you must repay the difference when filing your taxes. Check for changes in your expected annual income and household composition. Report the changes to the Marketplace where you enrolled. Check your new eligibility results and premium assistance amount. If asked for proof of income, submit it according to the notice. This process follows HealthCare.gov’s guidance on income and household changes. A decrease in income can also affect your assistance amount. Update your information as soon as possible after a change. Common Enrollment Mistakes Do not assume the enrollment deadline and payment deadline are the same date. Premium payment methods vary by insurer. HealthCare.gov instructs you to pay premiums directly to the insurer. Do not assume that creating an account completes your application. You must confirm that plan selection is complete. Do not mistake the final federal deadline for the January coverage deadline. The dates differ by coverage start date. Do not assume that lawful immigration status also makes you eligible for subsidies. You must check the 2027 immigration status requirements for assistance separately. Do not decide to renew automatically based only on last year’s premium. Check the new premium, provider coverage, and drug coverage. If you have not received instructions for your first premium payment, contact the insurer. Coverage will not begin unless payment is confirmed. If You Miss Open Enrollment You may apply outside open enrollment if you have a qualifying reason for special enrollment. Relevant events include losing insurance, getting married, having a baby, or moving. Check the requirements and supporting documents for each event through the official enrollment channel. You can apply for Medicaid and CHIP year-round. New York’s Essential Plan also allows year-round enrollment if you qualify. The end of open enrollment does not mean that applications for all public coverage have closed. FAQ Q. When do I need to enroll for coverage starting in January 2027? A.
