The COBRA enrollment window is one of the most strictly enforced deadlines in federal benefits law. If you're reading this because you think you may have missed it — or because you're trying not to miss it — this article gives you everything you need to know.
If you haven't hit your 60-day deadline yet, you still have all your options. Book a free call today — we can compare COBRA vs. marketplace plans and get you enrolled before the window closes. Don't read this article and then wait another two weeks.
The COBRA Deadline: Exactly How It Works
Under federal law (ERISA and the Public Health Service Act), you have exactly 60 days to elect COBRA continuation coverage after a qualifying event. For most laid-off employees, this clock starts on the later of:
- The date your employer-sponsored coverage ends, or
- The date your plan administrator mails your COBRA election notice
Your COBRA election notice is typically mailed within 44 days of your qualifying event. Your 60-day window starts from the date on the notice, not when you received it. If it was mailed on March 1 and arrived March 5, your deadline is still April 29 (60 days from March 1).
The date of your COBRA election period is printed on your notice. Look for language like "Election Period Ends" or "You must elect by [date]." If you can't find your notice, call your former employer's HR department or benefits administrator immediately and ask for it to be re-sent.
Your Timeline After Losing Job Coverage
Your last day of employer-sponsored health insurance coverage. Your clock starts here (or on the notice date, whichever is later).
You have both your COBRA option AND your ACA marketplace Special Enrollment Period open simultaneously. This is the best time to compare and choose. You can also elect COBRA retroactively.
You still have all options, but you're running out of time. If you've been procrastinating, act now. Both your COBRA window and your marketplace SEP end at day 60.
Last day to elect COBRA and last day of your marketplace Special Enrollment Period. After midnight tonight, both options close.
COBRA is permanently closed. Marketplace enrollment requires a new qualifying event or Open Enrollment. Short-term plans and Medicaid remain available.
What Happens If You Miss the COBRA Deadline
If your 60-day election window closes without you electing COBRA, two things happen simultaneously:
- You permanently lose your right to elect COBRA. There is no extension, no appeal, and no exception (with one narrow exception described below). This is a federal law deadline — your employer's plan administrator cannot waive it even if they wanted to.
- You may also lose your ACA marketplace Special Enrollment Period. Job loss opens a 60-day SEP for marketplace plans that runs concurrently with the COBRA window. If you miss the COBRA deadline, you've likely also missed the marketplace SEP — unless you have another qualifying life event.
This is the trap most people don't realize: your COBRA deadline and your marketplace Special Enrollment Period deadline are the same 60 days. If you miss one, you've almost certainly missed both. This can leave you uninsured until November 1 (Open Enrollment) unless you have a new qualifying event.
The One Exception: When You May Be Able to Challenge the Deadline
Federal law requires your plan administrator to send a COBRA election notice within 44 days of your qualifying event. If your plan administrator failed to send a proper notice — or sent it to the wrong address — you may have legal grounds to argue your election period never started.
This is narrow and requires documentation. If you believe you never received proper notice and your 60-day window has passed, consult a licensed ERISA attorney immediately. This is not a DIY situation — the deadlines and procedural requirements are complex.
What Options Do You Have After Missing the COBRA Deadline?
If you've genuinely missed both your COBRA deadline and your marketplace SEP, you still have paths to coverage. Some are better than others:
How to Avoid Missing the COBRA Deadline
If you're still inside your 60-day window, here's the action plan:
- Find your COBRA notice now. It should have arrived by mail within 6 weeks of your last day. Look for an envelope from your former employer's benefits administrator (not HR — it's often a third-party like Wage Works, COBRA Administration, or WEX Benefits).
- Do not elect COBRA first. Most people make the mistake of immediately electing COBRA without comparing alternatives. You can wait the full 60 days, and if you find a better option, you can let COBRA lapse or enroll in the marketplace instead.
- Know that COBRA is retroactive. This is the key insight most people miss: if you get sick during your 60-day window and haven't elected yet, you can still elect COBRA and pay the back premiums to get coverage going back to your last day of employer coverage. This means you don't need to elect COBRA "just in case" — you can wait, compare, and decide.
- Compare alternatives before the deadline. A licensed independent broker can pull marketplace quotes and short-term plan options for your situation in under 30 minutes. You'll make a much better decision with both numbers in front of you.
Use your 60-day window as a comparison-shopping period. Get quotes on marketplace and short-term alternatives. Elect the best option before day 60. If something happens during the window, you can retroactively elect COBRA to cover it. You don't have to rush — but you do have to act before the deadline.
How to Find Your COBRA Deadline If You've Lost Your Notice
If you can't find your COBRA election notice, do the following:
- Call your former employer's HR department and ask for the name and number of the COBRA administrator
- Contact the COBRA administrator directly and ask them to resend your election notice — they can verify your election period end date
- Check if your employer used a benefits portal (Workday, BambooHR, Gusto, etc.) where COBRA notices are sometimes sent electronically
- If in doubt, assume your 60-day clock started the day your coverage ended and count forward — err on the side of earlier action
A Word on the ACA Marketplace SEP and COBRA
Many people don't realize that losing job-based coverage opens a marketplace Special Enrollment Period that runs at the same time as the COBRA window — not after. This means you have 60 days to either elect COBRA or enroll in a marketplace plan. You don't need to wait to see if you'll elect COBRA before applying for marketplace coverage.
If you're leaning toward a marketplace plan, apply as soon as possible within your SEP window. Coverage can start as soon as the 1st of the following month after enrollment. Waiting until day 59 to enroll in a marketplace plan means you may have a 30-day gap in coverage while your new plan starts.

Can I get an extension on the COBRA deadline?
In almost all cases, no. The 60-day COBRA election period is set by federal law (ERISA) and cannot be extended by your employer or plan administrator. The only exception is if the plan administrator failed to provide proper notice of your COBRA rights — a narrow legal argument that typically requires an attorney.
Does missing the COBRA deadline affect my ACA marketplace options?
Yes. Your marketplace Special Enrollment Period runs concurrently with your COBRA window — both are 60 days from your coverage loss date. If you miss the COBRA deadline, you've almost certainly also missed your marketplace SEP. You'll need a new qualifying event to reopen marketplace enrollment.
Can I retroactively elect COBRA after I get sick?
Yes — but only if you're still within your 60-day election period. If something happens on day 45 of your window, you can still elect COBRA and pay the back premiums retroactively. After day 60, retroactive election is no longer possible.
What is the COBRA deadline for dependents?
The same 60-day election window applies to all covered family members. Each covered dependent can elect COBRA independently. A spouse who was covered under your employer plan has their own 60-day window to elect COBRA continuation.
