How to Get Health Insurance Through the ACA Marketplace

Last reviewed: November 2026
Verified against official agency guidelines

Apply at healthcare.gov or your state exchange during open enrollment (Nov 1 – Jan 15). You can get premium tax credits if your household income is between 100% and 400% of the federal poverty level. The larger credits that ran from 2021–2025 expired on 31 December 2025, so you will likely pay more than in 2025.

Be Careful

Don't make these mistakes

Missing the enrollment window. For 2027 coverage, open enrollment runs from November 1, 2026 to January 15, 2027. Enroll by December 15 for coverage starting January 1. Outside these dates, you need a qualifying life event, and you then get a 60-day special enrollment window.

Guessing your income wrong. Your help with costs is based on the income you expect to earn this year. Use your recent pay stubs to work this out. If you guess too high, you may have to pay back credits at tax time.

Expecting the bigger credits from past years. The larger credits that ran from 2021 to 2025 expired on 31 December 2025, so credits are now smaller than in 2025. You can get premium tax credits if your household income is between 100 percent and 400 percent of the federal poverty level. Compare plans and do not assume you will get a $0 premium.

Picking a plan without checking your doctors. Check that your doctors are in the plan network. Bronze plans have the lowest monthly cost but a high deductible. Silver plans give the best value if you qualify for extra savings.

Thinking you are covered before you pay. Pick a plan and enroll. Then pay your first premium directly to the insurance company. Your coverage does not start until your payment goes through. This is true even if the marketplace says "enrolled."

FAQ

Frequently Asked Questions

What income gets the biggest subsidy?

You can get premium tax credits if your household income is between 100% and 400% of the federal poverty level. For 2027 coverage, that is $15,960–$63,840 for a single person, per HealthCare.gov. The larger credits that kept premiums at 0–8.5% of income expired on 31 December 2025, and credits are now smaller than in 2025. Compare plans. Do not assume you will get a $0 premium.

Can immigrants use the marketplace?

Lawfully present immigrants can buy marketplace plans. From 1 January 2027, only some groups qualify for premium tax credits and extra savings. These groups are lawful permanent residents, Cuban/Haitian entrants, and COFA migrants. Other lawfully present immigrants can enroll without this help. This includes TPS holders and visa holders. DACA recipients cannot enroll in Marketplace coverage. Undocumented residents cannot use the federal marketplace. They may be able to use state programs or community clinics.

What happens if I miss open enrollment?

You must wait a full year. You do not have to wait if you have a qualifying life event. Examples are losing job coverage, getting married, getting divorced, having a new baby, or moving to a new state. Short-term plans are available, but they do not cover health problems you already have.
