  • Do I have to prove eligibility for a special enrollment period?

    FAQs

    Yes, in some cases. When you apply for Marketplace coverage and qualify for a Special Enrollment Period, the Exchange may request additional documents to confirm that you qualify for coverage in your Marketplace Eligibility notice. If you apply for Marketplace coverage following loss of other coverage, HealthCare.gov will let you select a health plan but will delay the effective date of coverage while it verifies your loss of other coverage. If the Marketplace cannot automatically…

  • Can I buy or change private health plan coverage outside of Open Enrollment?

    FAQs

    In general, you can have a special enrollment period (SEP) to sign up for Marketplace coverage during the year, other than during Open Enrollment period, if you have a qualifying event. Some examples of qualifying events include marriage, gaining a dependent, or loss of employment. Only one person in a household applying for coverage or financial assistance through the Marketplace must qualify for an SEP in order for the entire household to qualify for the…

  • When can small employers enroll in coverage through the SHOP Marketplace?

    FAQs

    Small employers can buy coverage for their employees through the SHOP Marketplace at any time during the year. HealthCare.gov no longer operates a SHOP Marketplace website for small employers. However, if you want to sponsor small group coverage through the Marketplace for your employees, you can contact insurance companies directly or work with a broker who is certified to sell SHOP policies. In HealthCare.gov states, you can find a SHOP-certified broker using the Find Local Help tool. Be…

  • 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 buy a plan in the Marketplace if I don’t have a green card?

    FAQs

You must be a lawfully present immigrant who is eligible for coverage, such as a lawful permanent resident (green card holder), certain types of visa holders, or a refugee or asylee. Deferred Action for Childhood Arrivals (DACA) is no longer considered an eligible immigration status for health coverage through the Marketplaces. You can find more information about qualifying statuses here.   You can also shop for health insurance outside of the Marketplace in…

  • I’m eligible for health benefits at work, but want to see if I can get a better deal on the Marketplace. Can I do that?

    FAQs

    You can always shop for coverage on the Marketplace, assuming you meet other eligibility requirements, but if you have access to job-based coverage that is determined to be affordable (no more than 9.96% of your household income in 2026), you won’t qualify for premium tax credits. Browse more questions in the Employer-Sponsored Health Coverage and the Marketplace section.

  • Who can buy coverage in the Marketplace?

Deferred Action for Childhood Arrivals (DACA) is no longer considered an eligible immigration status for health coverage through the Marketplaces. Not everybody who is…

  • I will lose my employer coverage mid-month. Can my Marketplace coverage start the same month when my old coverage is terminated?

    FAQs

    Yes, your Marketplace coverage will begin the first day of the month after you select your QHP during the special enrollment period triggered by your loss of other job-based coverage. If you sign up for a Marketplace plan during a special enrollment period, your coverage will take effect on the first day of the month after you select your plan, even if you made your selection after the 15th of the month. So, for example,…

  • I hear there is a special enrollment opportunity for people with very low income. How does that work?

    FAQs

    Starting August 25, 2025, the special enrollment opportunity that allowed individuals with incomes at or below 150% of the federal poverty level to sign up for Marketplace coverage year-round --simply due to their low income --was eliminated. Individuals at this income level might still qualify for special enrollment under other special enrollment events, such as when they lose coverage due to job loss or lose Medicaid coverage.

  • I’m covered under my parents’ plan and just had a baby. Will my parents’ plan cover my baby after he’s born?

    FAQs

    Your parents' plan, regardless of the source, is generally not required to cover your child as a dependent. Depending on your income, your child may be eligible for coverage under the Medicaid/CHIP program in your state. Or you can buy a family plan through the Marketplace and, depending on your income and whether health insurance is available from your own employer, you may be eligible for a premium tax credit and cost-sharing subsidy to reduce…
