Marketplace coverage is generally selected during Open Enrollment, but qualifying life events can create a Special Enrollment Period. Common examples include loss of qualifying coverage, marriage, a new dependent, aging off a parent's plan, and certain moves.
Many Special Enrollment Periods use a 60-day window before or after the event, but timing and documentation vary by event. The Marketplace determines eligibility after the application and verification process.

The 7 Most Common Qualifying Life Events
Not every life change qualifies. Here are the ones that matter most — and the ones I see constantly in my practice:
| Life Event | SEP Window | What You Need |
|---|---|---|
| Lost job-based coverage (laid off, fired, hours reduced, employer dropped coverage) | Often 60 days before or after coverage loss; confirm the exact Marketplace deadline | Letter from employer or COBRA notice showing coverage end date |
| Turning 26 (aging off parent's plan) | Often 60 days before or after the coverage loss; confirm the exact Marketplace deadline | Date of birth — coverage typically ends at month's end |
| Divorce or legal separation | May apply when coverage is lost; confirm the exact Marketplace deadline | Divorce decree or separation agreement + proof of prior coverage |
| Marriage | Often 60 days from the event; confirm the exact Marketplace deadline | Marriage certificate |
| Having or adopting a baby | Often 60 days from the event; confirm the exact Marketplace deadline and effective date | Birth certificate or adoption paperwork |
| Moving to a new coverage area | Timing varies; confirm the applicable Marketplace deadline | Proof of the move and any required proof of prior coverage |
| Losing Medicaid or CHIP | Timing varies under current Marketplace rules; confirm the applicable deadline | Medicaid termination letter |
Florida-specific note: Because Florida did not expand Medicaid under the ACA, adults without children earning below 100% FPL may fall into the "coverage gap" — they don't qualify for Medicaid and may not qualify for Marketplace subsidies. If you're in this situation, there are still options. Talk to a broker to explore alternatives.
Scenario 1: You Just Got Divorced
If you were on your spouse's employer plan, you're about to lose that coverage. In many divorces, coverage ends on the date the divorce is finalized or at the end of that month — it depends on the employer's policy.
You'll likely receive a COBRA offer. Here's the reality on COBRA: it's the same plan you had, but you're now paying the full premium — your share plus what your employer was paying — plus a 2% administrative fee. For most people, that means COBRA costs $500 to $1,200+ per month for individual coverage.
An ACA Marketplace plan may have a different premium, network, and cost-sharing structure than COBRA. Post-divorce income and tax-household information can affect premium tax credit eligibility, which the Marketplace determines after reviewing the application. Potential savings vary and are not guaranteed.
Divorce planning note: Use the Marketplace application rules for projected annual household income and tax-household status. A licensed broker can help organize the application information and compare available plans; the Marketplace determines premium tax credit and cost-sharing-reduction eligibility.
Scenario 2: You Just Turned 26
This one sneaks up on people. You've been on your parents' plan since college. You haven't thought about health insurance in years. Then you turn 26 and the coverage drops off — usually at the end of your birth month.
Marketplace premiums are age-rated, so age is one factor in the gross premium. Premium tax credit eligibility also depends on projected household income, tax-household information, access to other qualifying coverage, and current Marketplace rules.
A 26-year-old may be eligible for premium tax credits, but the net premium and available Silver plans vary by application, address, and plan year. The Marketplace determines eligibility and the final premium.
Scenario 3: You Lost Your Job
A layoff, termination, or employer closure that causes a loss of qualifying job-based coverage may open a Special Enrollment Period. Marketplace rules, timing, and documentation requirements apply.
COBRA preserves the prior employer plan, generally at the full premium plus any permitted administrative charge. A Marketplace plan may have a different premium, network, deductible, and prescription formulary. Compare the full terms before choosing; potential savings vary and are not guaranteed.
Projected annual household income is one important application input. Wages already earned, severance, unemployment compensation, and expected income for the rest of the year may affect the estimate. The Marketplace determines premium tax credit eligibility using the completed application and current rules.
Scenario 4: Marriage, Baby, or Relocation
These are the positive life changes — but they still create health insurance complexity.
Getting married: You can add your spouse to your plan, or you can both enroll in a new Marketplace plan together. Your combined household income determines your subsidy. Sometimes two individual plans are cheaper than one family plan; sometimes the opposite. Run the numbers both ways.
Having a baby: Birth or adoption may open enrollment rights for the child and household. Confirm the applicable deadline, documentation, and effective-date rules through the Marketplace.
Moving: Certain moves that change the coverage area may open a Special Enrollment Period, subject to Marketplace rules, prior-coverage requirements, and documentation. This can be relevant when moving to or from Polk County because plan availability varies by address.
What Happens If You Miss the 60-Day Window
If no other enrollment path applies after an SEP deadline, the household may need to wait for the next Open Enrollment Period or another qualifying event. Confirm current dates and coverage-effective rules through HealthCare.gov.
Available alternatives may include medically underwritten short-term coverage or other limited arrangements, subject to current Florida availability and policy terms. These options do not provide the same protections as ACA-compliant major medical coverage, and health sharing arrangements are not insurance.
Review the coverage gap carefully. Without comprehensive coverage, the household may be responsible for the full allowed or billed cost of emergency, hospital, diagnostic, and follow-up care. Verify any available enrollment path and its effective date before current coverage ends.
How to Enroll During Your SEP (Step by Step)
- Confirm your qualifying event and documentation. Know the exact date of the event and gather proof (termination letter, divorce decree, birth certificate, etc.).
- Go to Healthcare.gov or work with a broker. Create an account (or log in) and start an application. Select "I'm reporting a life change" when prompted.
- Enter your projected income for 2026. Use a supportable estimate of full-year household income. The Marketplace uses the completed application and current rules to determine premium tax credit eligibility.
- Compare plans carefully. Review premium, deductible, copays, coinsurance, annual out-of-pocket limit, network, and prescriptions. If you qualify for cost-sharing reductions, compare the eligible Silver options with the other available tiers.
- Enroll before day 60. Set a calendar reminder. Don't wait until the last week.
