Millions of Americans are about to let a deadline slip past them again.
Open enrollment for 2026 health coverage through the federal marketplace runs November 1 through January 15 in most states, but several states with their own exchanges close the window earlier.
If you miss it, you generally can't sign up again until next fall unless you hit a qualifying life event like a job loss, a move, or a new baby.
The first thing to do is confirm your actual deadline, not the one you saw on a billboard.
States including California, New York, Massachusetts, and a handful of others run their own marketplaces with different cutoff dates.
Go straight to healthcare.gov or your state exchange and check the calendar before you do anything else.
Next, pull your current plan's "Summary of Benefits" and compare it against at least two other options.
Premiums get the headlines, but the deductible, copays, and out-of-pocket maximum are where the real money hides.
A plan with a lower monthly bill can cost you far more the moment you actually need care.
Enhanced premium tax credits have made coverage dramatically cheaper for many middle-income households, but the amounts shift every year based on income and family size.
Update your income estimate honestly — if you underreport, you may owe money back at tax time.
Check whether your doctors and prescriptions are still covered.
Insurers trim their networks constantly, and a plan that covered your cardiologist last year might not this year.
Look up each provider and every medication by name in the plan's directory, and confirm the pharmacy you use is in-network.
Don't forget dental, vision, and any life or disability coverage your employer offers.
These add-ons are often cheaper through payroll than buying them separately, and the enrollment window is usually the only time you can add them without a health screening.
Watch out for the fine print on automatic renewal.
If you do nothing, most marketplaces will roll you into a similar plan — but not necessarily the same one.
Your premium can jump, your network can change, and your subsidy can shrink without a single email landing in your inbox.
One more trap: scam sites that look like the official marketplace and charge a "processing fee." Enrollment is free.
If a site asks for a credit card just to sign up, close the tab.
The real marketplace never charges you to apply.
Set a calendar reminder for two weeks before your deadline, gather your Social Security numbers, income documents, and current policy details, and knock it out in one sitting.
The bottom line: this is one of the few financial chores where a couple of hours can save you thousands over a year.
Treat the deadline like a bill that's due, not a suggestion.
Final Thoughts
Most people who overpay for coverage simply never bothered to shop — don't be one of them.
