Your Marketplace plan has worked fine this year, and you would rather not deal with Open Enrollment again. So does Marketplace insurance automatically renew? In most cases, yes. If you do nothing, the Marketplace will usually put you back into coverage for next year. But automatic renewal carries over last year's information. It does not re-check whether that plan, and that subsidy, still fit you. Here is how auto re-enrollment works for 2027 and what to look at before you let it happen.
Does Marketplace insurance automatically renew?
On HealthCare.gov, which Florida and most other states use, the rule is simple. If you have Marketplace coverage in December and have not chosen a plan or ended your coverage by December 15, the Marketplace re-enrolls you automatically. The new coverage starts January 1, so there is no gap.
State-run Marketplaces follow the same general approach, but their deadlines and steps can differ, so check with your state's exchange if you do not use HealthCare.gov.
For 2027, Open Enrollment runs from November 1, 2026, to January 15, 2027. December 15 is the last day to pick a plan that starts January 1. If you change plans between December 16 and January 15, the new plan replaces your auto-renewed one and starts February 1. A federal rule that would have ended Open Enrollment in December was struck down in June 2026. The government has appealed, with oral argument scheduled for October 30, 2026, so the schedule could still change. Our Open Enrollment 2027 guide tracks the dates.
Which plan you get renewed into
Automatic re-enrollment follows an order set by federal regulation (45 C.F.R. § 155.335(j)). In plain terms:
- If your current plan is still offered, you are renewed into the same plan.
- If that plan is discontinued, but your insurer still sells a similar product in your area, you are moved to the closest match from the same insurer. That usually means the same metal level and the most similar network.
- If your insurer leaves the Marketplace in your area entirely, you may be placed with a similar plan from a different insurer, where state rules allow it.
The words to watch are "most similar." A replacement plan can have a different deductible, a different drug list, or a narrower network, and your doctors may not be in it. If your plan is ending for 2027, read our guide to what to do when your health plan is discontinued before you let the Marketplace choose for you.
Why the renewed plan can cost more than you expect
Even when you keep the exact same plan, what you pay can change on January 1. Three things move independently of you:
- The plan's full price. Insurers file new rates every year, so the sticker price of your plan will generally be different in 2027.
- Your subsidy. The premium tax credit is based on the cost of a benchmark silver plan in your area. When that benchmark shifts, your credit shifts too, even if your income stays the same.
- The plan lineup around you. A plan that was a good deal this year may be outpriced by a new option next year, and auto re-enrollment will not switch you to it.
Subsidy rules have also changed. The enhanced premium tax credits that applied through 2025 expired, and as of this writing Congress has not restored them. That brings back the income cliff at roughly four times the federal poverty level. Above it, you generally get no premium tax credit. If your household income is near that line, a small change in your estimate can mean a large change in your premium. Our overview of the 2026 ACA subsidy changes explains how it works.
Why your subsidy may be wrong if you don't update your application
HealthCare.gov says it plainly: if you do not update your income and household information, you could qualify for more savings than you are getting, or you could get less than you qualify for. If you get too much in advance, you may have to pay back the difference when you file your federal taxes.
Two situations are especially easy to miss:
- Your income or household changed. A raise, a new job, a marriage or divorce, a new baby, or a child aging out of your tax household all change what you qualify for. Auto re-enrollment uses the information already on file.
- You never gave permission to check your tax data. Under 45 C.F.R. § 155.335(l), if the Marketplace does not have an active authorization to get your updated tax information, it can only renew your plan. It cannot re-check your eligibility for financial help. Updating your application, and renewing that permission, fixes this.
Tax filing matters too. The requirement to file and reconcile your advance credit is statutory. A separate rule that would have cut off advance credits after a single missed reconciliation is currently paused by a court, as we explain in our post on losing a subsidy over unfiled taxes. If you received advance credits and have not filed, talk to a tax professional before Open Enrollment.
What to check before December 15
Letting the Marketplace auto-renew your plan is a reasonable choice. Just make sure it is a choice. Before December 15:
- Read your notices. The Marketplace sends an eligibility notice with its projected savings for next year, and your insurer sends a renewal notice. Check whether either one says your plan is changing or ending.
- Update your application with your best estimate of 2027 household income and any change in who is in your household.
- Check your doctors and hospitals against the 2027 network, not this year's. Networks change from year to year, and our guide to in-network versus out-of-network care explains why it matters.
- Check your prescriptions against the 2027 drug list and look at which tier each one falls on.
- Compare your renewed plan's premium, after the subsidy, with at least two alternatives, and compare deductibles and out-of-pocket maximums, not just the monthly price.
- If your plan is ending, choose its replacement yourself rather than accepting the Marketplace's closest match without checking it.
If you already missed December 15
You can still act until Open Enrollment closes January 15, 2027. If you were auto-renewed and then pick a different plan in that window, the new plan starts February 1, and your auto-renewed plan covers January. Once Open Enrollment ends, you generally cannot change plans until next year unless a life event qualifies you for a Special Enrollment Period.
