The 60-Day Special Enrollment Period and the COBRA Trap
Losing job-based coverage opens a 60-day special enrollment period, and it opens up to 60 days before the loss. Dropping COBRA on purpose does not.
Losing job-based coverage opens a special enrollment period of 60 days after the loss, and it also opens up to 60 days before1. Electing COBRA does not close it. Voluntarily dropping COBRA is not a qualifying life event2.
The COBRA vs Marketplace calculator counts both windows down from the date coverage ends. This page explains what each one does.
The window opens twice
HealthCare.gov describes the forward-looking half plainly: you may apply if you “expect to lose coverage in the next 60 days”. The backward-looking half is the familiar one, and it is stated for job-based coverage as “You can enroll in a Marketplace plan within 60 days of losing your job-based coverage.”
The forward-looking half exists so that an application can be made before the coverage stops rather than after it. HealthCare.gov’s own framing is that you may apply when you expect to lose coverage in the next 60 days.
COBRA and the Marketplace run on separate clocks
| Clock | Length | What it decides |
|---|---|---|
| COBRA election | 60 days3 | Whether the old employer plan can be continued |
| Marketplace special enrollment | 60 days after (and up to 60 days before) losing job-based coverage1 | Whether a Marketplace plan can be bought outside open enrollment |
The two run at the same time from the same event. Electing COBRA inside the first window does not spend the second one. Within the special enrollment period you may still drop the COBRA election and take a Marketplace plan instead.
The trap
Once the special enrollment period has closed, the position changes. HealthCare.gov states it in two sentences: “Voluntarily dropping COBRA doesn’t count. Choosing to stop paying COBRA premiums on your own doesn’t qualify.”
Exhausting COBRA is different. “When your COBRA coverage ends, you have 60 days to enroll in a Marketplace health plan through a Special Enrollment Period.” Reaching the end of the 18, 29 or 36 months opens a fresh window; walking away early does not.
So the choice made in the first 60 days is the one that matters. After it, the practical routes into a Marketplace plan are the end of the COBRA period, a different qualifying life event, or the next open enrollment.
Where the annual window sits
Outside a special enrollment period, coverage is bought during open enrollment. HealthCare.gov’s dates page puts the special enrollment route this way: “Get coverage between January 16 and October 31 if you qualify for a Special Enrollment Period due to a life event.”
For 2027 coverage the annual window runs November 1, 2026 – January 15, 20274, which the open enrollment page sets out with the January 1 coverage deadline.
How long is the special enrollment period after losing a job?
60 days after (and up to 60 days before) losing job-based coverage1. The 60 days after the loss are the well-known half; the same event also lets you apply up to 60 days before coverage ends, which is how a gap in cover is avoided.
Can I switch from COBRA to a Marketplace plan?
Yes, within the special enrollment period that the original loss of coverage opened, and yes during any open enrollment period. Outside those, HealthCare.gov lists “your COBRA coverage is running out” as the qualifying route.
What happens if I drop COBRA?
Nothing opens. “Voluntarily dropping COBRA doesn’t count. Choosing to stop paying COBRA premiums on your own doesn’t qualify.” The next chance to buy a Marketplace plan is open enrollment or a separate qualifying life event.
What happens when COBRA runs out?
Exhausting the coverage period is itself a qualifying event. HealthCare.gov states that when COBRA coverage ends “you have 60 days to enroll in a Marketplace health plan through a Special Enrollment Period.”
Can I apply before my coverage actually ends?
Yes. The Marketplace accepts an application from someone who expects to lose coverage in the next 60 days, and that is the path that lets new coverage begin the day the old plan stops.
Does electing COBRA use up my special enrollment period?
No. Both clocks start from the same loss of coverage and run in parallel. An election made in the first days does not shorten the Marketplace window that is still open.
What if I miss the 60 days?
The route is open enrollment, unless another qualifying life event occurs first. HealthCare.gov’s special enrollment page lists the events that count and the window each one opens.
