Change in February effectuated enrollment, by state, 2025-2026

How Has ACA Marketplace Enrollment Changed Across States in 2026?

ACA Marketplace enrollment fell this year in every state except New Mexico, which was the only state to fully replace the enhanced premium tax credits that expired last year with a state-funded subsidy, according to a new KFF analysis of effectuated enrollment data. The Marketplace enrollment decline—the first in seven years—follows several years of rapid enrollment growth and coincides with the end of the enhanced federal subsidies.

How Much and Why ACA Marketplace Premiums Are Going Up in 2027

ACA Marketplaces insurers are proposing a median premium increase of 15% in 2027, according to KFF’s updated analysis of 276 insurers with publicly available filings across all 50 states and the District of Columbia. This is the second consecutive year of double-digit premium hikes. Last year’s median nationwide proposed rate change was 18%, and the median finalized rate change was 20%. While this proposed rate change is lower than last year, it represents the second-highest requested rate change since 2018, as premium growth had been relatively flat in this market for several years.

KFF’s Cynthia Cox examines the ACA’s record and the broader underlying question it raises: what’s a fair price for Americans people to pay for health care?

  • Where can I get help with my Marketplace application?

    FAQs

    All Marketplaces are required to offer "Navigator" programs to help consumers review their plan choices, complete their application, or apply for financial assistance. Navigators can also assist consumers applying for Medicaid or CHIP. Additionally, Navigators can help consumers with post-enrollment support, such as appealing Marketplace decisions. Navigators are paid by the Marketplace, not by health plans, and they must complete Marketplace training and be free from conflicts of interest. You may also be able to…

  • How long after I enroll in a plan will coverage take effect?

    FAQs

    During Open Enrollment in HealthCare.gov and some other states, if you enroll in a private health insurance plan by December 15 and make your first premium payment by the due date specified by your plan, your new health coverage will start January 1. If you sign up after December 15, your coverage will begin on February 1. If you sign up for a Marketplace plan during a special enrollment period, your coverage will usually take…

  • Can I adjust the level of subsidy I collect in advance when my income goes up or down during the year? How often during the year can I make adjustments?

    FAQs

    You can make adjustments during the year whenever you need to. There is no limit to the number of times a person may report income, family, or insurance-eligibility changes to the Marketplace. Changes that you report will be verified by the Marketplace. Then the Marketplace will send you a notice (called a redetermination notice) showing your revised eligibility for premium tax credits and cost-sharing reductions. The adjustment should take effect by the first day of…

  • My 24-year-old daughter is eligible for premium tax credits and a cost-sharing reduction. We are not eligible for any financial assistance, but we would all like to enroll in the same Marketplace plan....

    FAQs

    You do not need to claim your daughter as a tax dependent to be covered on your Marketplace health plan; however, since you do not claim her as a tax dependent, she will likely have to submit a separate application, and she likely will not be able to apply her premium tax credits to your shared plan. Additionally, because you do not qualify for cost-sharing subsidies, she will not be able to apply hers to…

  • I received a Form 1095-A from the Marketplace. What is that?

    FAQs

    Form 1095-A gives you information about the amount of advance premium tax credit (APTC) you received during the previous year. A copy of this form is also reported to the IRS. Keep this form with your other tax records. The APTC you received was based on the annual income you estimated you would earn when you signed up for Marketplace coverage. Now you must file a federal income tax return to compute your actual income for that coverage…

  • I had a Marketplace plan last year, but paid the full premium myself because I made too much to qualify for premium tax credits. When I did my taxes though, my income for the year ended up being less th...

    FAQs

    Yes. Premium tax credits can be claimed in advance (during the year) or when you file your taxes. To claim the credit, you will need to file a federal income tax return and Form 8962. Follow the instructions on Form 8962 to determine the amount of tax credit you should receive as a refund when you file your taxes.

  • What is Form 8962?

    FAQs

    If you received an advanced premium tax credit (APTC) through the Marketplace last year, you must file a Form 8962 with your federal income tax return in order to "reconcile" your estimated and actual income for the year, even if you estimated your income perfectly. You can get a blank Form 8962 from the IRS website, or, if you use tax preparation software, the form will be automatically generated for you. The instructions for Form…

  • What happens if I’m late with a monthly health insurance premium payment?

    FAQs

    It depends on whether you are receiving advanced premium tax credits. If you receive a premium tax credit, your insurer must provide a 90-day grace period to pay all past-due premiums. If the amount owed for all outstanding premium payments is not paid in full by the end of the grace period, the insurer can terminate coverage. However, the grace period only applies if you have paid at least one month’s premium within the current…

  • I have COBRA, but it’s too expensive. Can I drop it during Marketplace Open Enrollment and enroll in a Marketplace plan instead?

    FAQs

    During Marketplace Open Enrollment, you can sign up for a Marketplace plan even if you already have COBRA. You will have to drop your COBRA coverage effective on the date your new Marketplace plan coverage begins. After Marketplace Open Enrollment ends, however, if you voluntarily drop your COBRA coverage or stop paying premiums, you will not be eligible for a special enrollment opportunity to enroll in a Marketplace plan and will have to wait until…

  • I heard the Affordable Care Act’s individual mandate ended. Does it still make sense to sign up?

    FAQs

    While there is no longer a federal tax penalty for being uninsured, some states (CA, MA, NJ, and RI) and DC have enacted individual mandates and may apply a state tax penalty if you lack health coverage for the year. Regardless of any tax penalty, it is still important to have insurance coverage to help reduce the risk of large medical bills if you get sick, to pay for medications, and to pay for check-ups…
