Did Open Enrollment Get Shorter for 2027?
Short answer: no. Open enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027 — the same window as always.
If you’ve read otherwise, you’re not imagining it. There was a real federal rule that would have ended open enrollment on December 15. It just doesn’t apply anymore, and a lot of articles written before June never got updated.
What almost happened
In 2025, the federal government finalized a rule called the Marketplace Integrity and Affordability rule. Among other changes, it would have shortened open enrollment on HealthCare.gov to November 1 through December 15 — a full month less — starting with 2027 coverage. It also would have limited state-run marketplaces from extending past December 31.
That got a lot of coverage at the time, and reasonably so. Losing a month matters when you’re comparing plans.
What actually happened
In June 2026, a federal judge in Maryland struck down that provision, along with several others in the same rule. The government has appealed and that case is still moving, but the shortened window never took effect.
In July 2026, the Centers for Medicare & Medicaid Services confirmed the practical result: open enrollment at the federal marketplace begins November 1, 2026, and the dates were not changed.
So the deadline you’re planning around is January 15, 2027.
Why you’ll still see the wrong answer
Three reasons, and they’ll all be in play this fall:
Articles written between mid-2025 and June 2026 stated December 15 correctly at the time. Most were never updated.
The appeal is ongoing, so some coverage hedges or describes the rule as though it’s still in force.
Future years are genuinely unsettled. If the appeal succeeds, a shorter window could return for 2028 or later. That uncertainty gets blurred into this year.
If you see December 15 in an article, check its date before you plan around it.
The date that actually costs people money
Here’s the part that matters more than the deadline itself.
January 15 is the last day to enroll. But to have coverage starting January 1, you generally need to be enrolled by mid-December. Enroll after that and you’re covered from February 1 — which means a gap in January.
Most people who get burned by open enrollment aren’t the ones who missed January 15. They’re the ones who enrolled on January 10, assumed they were covered, and found out in the middle of the month that coverage hadn’t started.
If you want January 1 coverage, treat mid-December as your real deadline.
If your state runs its own marketplace
State-based marketplaces set their own enrollment windows, and several run later than the federal deadline. Some also open earlier.
I’d rather you check than take a date from an article — including this one. State deadlines shift, and a few states haven’t published their 2027 dates yet. If you tell me where you live, I’ll tell you what applies to you.
What hasn’t changed, and probably should worry you more
The enrollment window is back to normal. The subsidy situation is not.
The enhanced premium tax credits that had been in place since 2021 expired at the end of 2025. That brought back the hard cutoff at 400% of the federal poverty level — and above that line there’s no cap on how much subsidy you have to repay if you underestimated your income.
For anyone whose income moves during the year — self-employed, commission-based, contract work — that’s a far bigger financial risk than a deadline. And unlike the deadline, it’s real and in effect right now.
What to do about it
If you’re shopping for 2027 coverage, the useful move isn’t marking January 15 on a calendar. It’s knowing before November whether you qualify for a subsidy, whether your income puts you near the cliff, and whether the marketplace or a private plan makes more sense for you.
That’s a fifteen-minute conversation, and it’s free.
