COBRA keeps your exact employer plan, and you usually pay the full premium, both your former share and the employer's share, plus a permitted administrative charge of up to 2%, unless an employer contribution continues. A Marketplace plan may come with a premium tax credit, but eligibility depends on your household income for the entire coverage year, not on the pay you stopped receiving. That last point catches people: wages you already earned earlier in the year still count, so a mid-year job loss does not automatically produce a low income figure.
Neither option wins on principle. This guide lays out how each works, what the real deadlines are, and how to compare total cost for the months you actually need coverage.
What Is COBRA and How Does It Work?
COBRA (Consolidated Omnibus Budget Reconciliation Act) gives you the right to continue your employer's group health plan after coverage ends because of job loss, reduced hours, or certain other qualifying events.
- Duration: Generally up to 18 months for job loss or reduced hours. Other qualifying events and available extensions can run longer, in some cases up to 36 months.
- Cost: Usually the full premium, your former share plus the employer's share, plus a permitted administrative charge of up to 2%. Some severance agreements continue an employer contribution for a period.
- Coverage: The same plan you had as an employee, with the same network and benefits
- Election period: At least 60 days, measured from the later of the date the election notice is furnished to you or the date you would lose coverage
- First payment: Generally due no earlier than 45 days after the date you elect
- Applies to: Employers with 20 or more employees. Some states have their own continuation laws for smaller employers.
Your plan documents and election notice control your actual dates. Read them rather than relying on a general article, including this one.
What Is the Marketplace and How Does It Work?
The ACA Marketplace sells individual and family plans that cover the essential health benefits and cannot deny you for pre-existing conditions.
- Premium tax credit: May reduce what you pay, based on household income for the coverage year and other eligibility rules. The Marketplace makes that determination.
- Special enrollment period: Losing job-based coverage generally opens a 60-day window, with documentation required
- Plan levels: Bronze, Silver, Gold, and in some areas Platinum, trading premium against cost sharing
- Cost-sharing reductions: Extra savings available only on Silver plans, and only for households the Marketplace determines eligible
- No fixed end: Unlike COBRA, which is time limited, Marketplace coverage renews annually
Can You Apply While You Are Still on COBRA?
Yes. You can complete a Marketplace application while you are enrolled in COBRA. You do not have to cancel first, and cancelling first is a bad idea, because it can leave you uninsured with nothing confirmed.
Applying is not the same as being enrolled. Generally you cannot claim the premium tax credit for a person for any month that person is enrolled in COBRA continuation coverage. Being offered COBRA without enrolling is a different situation, and an offer of continuation coverage you do not accept does not by itself block the credit (IRS premium tax credit questions and answers). Before you cancel anything, confirm in writing that you are eligible to enroll, the exact effective date, and the premium required to put the new plan in force.
Which Situations Let You Switch Mid-Year?
| Situation | Can you switch? |
|---|---|
| It is the annual open enrollment window | Generally yes, if otherwise eligible |
| Your original loss of job-based coverage is still within the 60-day window | May allow a special enrollment period |
| Your COBRA coverage is exhausted | May allow a special enrollment period |
| Your former employer stops contributing toward COBRA, so you must pay the full cost | May allow a special enrollment period |
| You choose to cancel COBRA early | Generally no |
| You stop paying COBRA premiums | Generally no |
| You have another qualifying life event, such as marriage, a birth, or a move | May allow enrollment under that event's rules |
The loss of an employer contribution toward COBRA is the trigger people most often miss. If a severance agreement paid part of your COBRA premium and that subsidy ends, that change can matter. Our dedicated guide walks through each trigger in detail: switching from COBRA to a Marketplace plan.
About the Retroactive Election
COBRA is often described as a free 60-day safety net. It is not free. If you elect COBRA later in the window, you generally owe premiums retroactive to the date coverage was lost, so a delayed election is a bill you accept rather than a bill you avoid. Meanwhile, the Marketplace has its own separate deadline running, and missing it is a real cost too.
The practical version: do not treat the delay as costless, keep both deadlines written down, and decide before either one expires.
How Should You Compare Cost?
Compare the remaining months you need, not one month's premium. For each option add the remaining premiums, plus the cost sharing you realistically expect, plus what the network difference is worth to you.
Hypothetical arithmetic only. No premium tax credit assumed, no quote implied, and not anyone's actual cost:
| Option | Premiums for 5 months | Expected cost sharing | Total |
|---|---|---|---|
| Stay on COBRA | $800 x 5 = $4,000 | $500 (deductible mostly met) | $4,500 |
| New Marketplace plan | $500 x 5 = $2,500 | $2,300 (deductible resets) | $4,800 |
The arithmetic is the point, not the numbers. A lower premium does not automatically win, because a new plan normally starts a new deductible and out-of-pocket accumulator. Put your own figures into the same two lines.
Why Your Income Figure Is Higher Than You Think
Premium tax credit eligibility uses household income for the full coverage year. Wages you already earned before the job ended still count, along with severance, unemployment compensation, a spouse's income, and investment income. Someone who earned a full salary through August will usually report a much higher annual figure than their current monthly cash flow suggests.
That figure is also a projection you keep current. Update the application when your situation changes, and if the advance credit paid on your behalf ends up exceeding the credit you are allowed, you repay the difference when you file. The IRS states that for tax years after 2025 there is no repayment limitation. For how to build the number, see estimating Marketplace income.
When Does COBRA Tend to Make Sense?
- You are mid-treatment with a specific provider and continuity matters more than premium.
- You have already paid down a large deductible this year and only need a few more months.
- New employer coverage starts within a month or two.
- Your household income for the year is high enough that little or no premium tax credit is in play.
When Does the Marketplace Tend to Make Sense?
- You need coverage for the rest of the year or longer, past the point where your COBRA continuation would end.
- Your expected household income for the coverage year is low enough that a premium tax credit may apply.
- You are covering a family, where the full unsubsidized group premium is heaviest.
- You are flexible about providers, or you have verified your providers in the new plan's network.
Decision Framework: 4 Questions
- 1. What is your realistic household income for the whole coverage year? Include wages already earned, severance, and unemployment.
- 2. Are you mid-treatment or attached to a specific provider? If yes, price continuity before you move.
- 3. How much of this year's deductible have you already paid? A reset can outweigh a lower premium.
- 4. How many months of coverage do you actually need? Compare total cost over those months, not per-month premium.
Frequently Asked Questions
Do I have to cancel COBRA before I apply for a Marketplace plan?
No. You can apply while enrolled in COBRA. Confirm eligibility, the effective date, and the required premium before you cancel anything.
Can I get a premium tax credit while I am enrolled in COBRA?
Generally no, not for the months you are actually enrolled in COBRA. Being offered COBRA and declining it is different, and an unaccepted offer does not by itself disqualify you. You can still submit a Marketplace application while enrolled, and you should not cancel COBRA until the replacement coverage and its effective date are confirmed (IRS).
How long is the COBRA election period?
At least 60 days, measured from the later of the date the election notice is furnished or the date coverage would be lost. Your notice controls the exact dates.
What happens when COBRA runs out?
Exhausting COBRA may open a special enrollment period on the Marketplace, generally with a 60-day window. Do not let coverage lapse while you sort it out.
Does my deductible transfer to the new plan?
Normally no. Ask the new carrier directly rather than assuming credit for what you have already paid.
The Bottom Line
COBRA buys continuity at full price. The Marketplace may buy a lower net cost, but only if your coverage-year income and the plans available where you live actually work out that way. Run both totals for the months you need, verify your providers and prescriptions, and confirm every deadline in writing before you cancel anything.
