Every year, a quiet but critical date sneaks up on older adults who buy their own health insurance: December 15. That’s the deadline to choose or update a Marketplace plan if you want your coverage to begin on January 1, 2026, per an email sent from HealthCare.gov to Smart Senior Daily.
If you’ve seen the reminder emails from HealthCare.gov lately, that’s what they’re talking about. They look a little abrupt because they’re designed to be fast warnings—not full explanations.
Here’s what’s really going on
Most people who enroll through the Marketplace qualify for substantial financial assistance. Federal data shows that 4 out of 5 customers can find a plan for $21 or less per month after subsidies are applied. Seniors who aren’t yet Medicare-eligible—especially early retirees or those in the “Medicare waiting gap”—tend to see some of the biggest reductions.
But there’s a catch:
To find out what you qualify for, you must create an account or update last year’s application. Your subsidy amount is recalculated every year, even if your income or household hasn’t changed.
The enrollment window is narrow, and if you miss the Dec. 15 cutoff, your coverage won’t start until February. For anyone managing chronic conditions, prescriptions, or upcoming procedures, that delay can be costly.
So if you rely on Marketplace coverage—or you have a spouse who isn’t yet on Medicare—take five minutes this week to log in, update your information, and compare plans.
It’s the easiest way to make sure you’re covered when January rolls around.
