The short answer
If you have a Marketplace plan in December and take no action, HealthCare.gov will generally re-enroll you for the next year: in the same plan if it's still offered, or in a similar plan if it isn't. That keeps you covered, which is good. But auto-renewal carries last year's choices into a new year, and in some cases it isn't available at all.
For 2027 coverage in Utah and Wyoming, Open Enrollment runs November 1, 2026 to January 15, 2027, and December 15 is the deadline for coverage that starts January 1. The best use of that window is a deliberate renewal: update your information, compare, then keep or switch on purpose.
What can change without you noticing
- Your premium. Insurers set new prices every year, and your tax credit is recalculated, so your share of the premium can rise even if the plan's sticker price barely moves.
- The plan itself. Deductibles, copays and out-of-pocket maximums can change for the new year.
- Your doctors and hospital. Networks change. A doctor who was in network this year may not be next year.
- Your prescriptions. A drug can move to a higher-cost tier or come off the plan's list.
- Your plan may be discontinued. If your insurer stops offering it, you may be moved into a similar plan you didn't choose. A discontinued plan can also qualify you for a Special Enrollment Period.
- Better options may exist. New plans or insurers can enter your county, and a plan in a different metal level may now cost less for your situation.
Why your income estimate matters more now
Your premium tax credit is paid to your insurer in advance, based on the income you expect, and then settled on your tax return. If your actual income comes in higher, you pay back the difference.
Until 2025 there were caps on how much most people had to repay. A federal law passed in 2025 removed those caps starting with 2026 coverage, so if your income turns out higher than your estimate, you may owe back the full excess when you file. An auto-renewal that carries forward an old income estimate is exactly how people end up with that bill.
The enhanced tax credits that made coverage cheaper from 2021 through 2025 also expired at the end of 2025, so many households saw higher net premiums in 2026. Congress has debated bringing them back. Until something passes, compare your actual 2027 cost rather than assuming it matches this year's.
A quick example
Picture a self-employed couple in Cheyenne who let their plan renew last year. Over the year, the husband's freelance work picked up, and the specialist he sees left their plan's network. Because nothing was updated, their monthly tax credit was still based on the old, lower income, and they found out about the network change at the specialist's front desk. A 20-minute review in November would have caught both: a higher income estimate (a smaller credit now instead of a tax bill later) and a plan that still includes his specialist.
Your 20-minute renewal routine
- Log in to HealthCare.gov and review your application.
- Update your 2027 income estimate for everyone in your tax household: jobs, self-employment, retirement withdrawals, everything that counts.
- Update your household: marriage, divorce, a new baby, a child who moved out or got job coverage.
- See your new tax credit, then compare at least three plans by estimated yearly cost (premium plus deductible and copays), not premium alone.
- Check your doctors and drugs in each plan's network and drug list.
- If you qualify for extra savings on Silver plans, look at Silver first; that's the only metal level where cost-sharing reductions apply.
- Choose by December 15 for January 1 coverage, and pay your first premium so the coverage actually starts.
If your income changes during the year
Report changes on HealthCare.gov as they happen, not just at renewal. A raise, a new job with health coverage, or a spouse's change in work can all change your tax credit. Updating promptly keeps your monthly credit closer to what you'll actually qualify for at tax time.
Nevada is different
Nevada runs its own exchange, Nevada Health Link, with its own website and dates. The same advice applies (update, compare, choose on purpose), but check Nevada Health Link's deadlines rather than HealthCare.gov's. Our Nevada-licensed agents Eric Jenkins and Angie Oceguera can help (Nevada help).

Frequently Asked Questions
Does my ACA plan renew automatically?
Usually. If you have Marketplace coverage in December and take no action by December 15, HealthCare.gov generally re-enrolls you in the same plan, or a similar one if yours is discontinued. In some cases you won't be re-enrolled automatically, so check your account.
Why should I re-shop my Marketplace plan for 2027?
Premiums, deductibles, networks and drug lists can all change, and your tax credit is recalculated. Comparing takes about 20 minutes and is the only way to know whether last year's plan is still your best option.
What happens if my income ends up higher than I estimated?
You pay back the extra tax credit when you file. Starting with 2026 coverage, the old repayment caps no longer apply, so you may owe the full difference. Keep your income estimate current.
What's the deadline to change plans for January 1, 2027?
December 15, 2026 on HealthCare.gov (Utah and Wyoming). Open Enrollment continues to January 15, 2027 for coverage starting February 1. Nevada uses Nevada Health Link, which sets its own dates.
