Getting a new job can be a qualifying life event for health insurance, but the job itself is not what counts — the trigger is the change in your coverage. Leaving your old employer’s plan, becoming eligible for a new employer’s plan, or both will open a special enrollment period that lets you sign up outside the annual open enrollment window. You generally have 60 days from the coverage change to pick a plan through your new employer or the Health Insurance Marketplace.
What Actually Triggers the Special Enrollment Period
Federal rules list specific events that open a special enrollment period. When you change jobs, the most common one is losing minimum essential coverage, which happens when your old employer’s plan ends.1eCFR. 45 CFR Part 155 – 155.420 Special Enrollment Periods The last day you were covered is the official loss date, and your 60-day clock runs from there.
The second common trigger is gaining eligibility for new coverage. If your new employer offers a group health plan, a Qualified Small Employer Health Reimbursement Arrangement, or an individual coverage HRA, a special enrollment period opens on the date that new coverage can take effect.1eCFR. 45 CFR Part 155 – 155.420 Special Enrollment Periods This applies even if you were uninsured before you started.
If your new job does not offer insurance, the job alone gives you no new triggering event. But if you lost coverage from your previous employer, that loss is still a trigger. You can use it to buy a Marketplace plan, or if you already have one, update your income so your subsidy reflects your new situation.2HealthCare.gov. Health Care Coverage Options for Unemployed
Moving From Part-Time to Full-Time
You do not have to change employers for a qualifying event to happen. Under the ACA, a full-time employee averages at least 30 hours per week. If you move from part-time to full-time at the same company and become newly eligible for the health plan, that eligibility change opens an enrollment window with your employer, even though you never left.
The 60-Day Enrollment Window
Once a triggering event happens, you have 60 days to pick a plan.1eCFR. 45 CFR Part 155 – 155.420 Special Enrollment Periods Miss the deadline and you typically wait until the next open enrollment for Marketplace coverage. For plan year 2026, open enrollment runs from November 1, 2025, through January 15, 2026.3Centers for Medicare & Medicaid Services. Plan Year 2026 Marketplace Plans and Prices Fact Sheet
If you didn’t know your coverage had ended — say your former employer dropped it earlier than expected — the 60 days starts from the date you knew or reasonably should have known.1eCFR. 45 CFR Part 155 – 155.420 Special Enrollment Periods
When New Coverage Starts
The effective date of a new Marketplace plan depends on timing. Pick your plan on or before the day your old coverage ends and the new coverage starts the first day of the month after the triggering event. Pick it after, and coverage generally starts the first day of the month following your plan selection.1eCFR. 45 CFR Part 155 – 155.420 Special Enrollment Periods Moving quickly shrinks any gap.
How Long the New Employer Can Make You Wait
If your new employer offers a group health plan, federal law caps the waiting period at 90 days from your start date.4eCFR. 45 CFR 147.116 – Prohibition on Waiting Periods That Exceed 90 Days An employer can tack on an orientation period of up to one month before the waiting-period clock starts, but the combined delay still cannot push coverage beyond roughly four months after your first day. Many employers set shorter waits of 30 or 60 days.
Covering the Gap Between Jobs
Even with the 90-day cap, you may face a stretch with no coverage between the old plan ending and the new one starting. Two options can fill it.
- A Marketplace plan. Losing your old job’s coverage qualifies you for a special enrollment period, so you can buy a Marketplace plan for the weeks or months until the new employer plan starts, then cancel it. Depending on your income, premium tax credits may lower what you pay each month.5HealthCare.gov. See Your Options If You Lose Job-Based Health Insurance
- COBRA continuation coverage. If your former employer had 20 or more employees, you can stay on the old plan through COBRA for up to 18 months. You pay the full premium — both halves plus a small administrative fee. Your doctors and network stay the same, but the cost is often much higher than a subsidized Marketplace plan.
COBRA Has a Trap
If you elect COBRA, how you leave it matters. Voluntarily dropping COBRA before the maximum period ends generally does not open a new special enrollment period, so you’d have to wait for the next open enrollment to get a Marketplace plan.6U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers Let COBRA run out on its own and you do qualify for a new special enrollment period to join another group plan or a Marketplace plan.7eCFR. 29 CFR 2590.701-6 – Special Enrollment Periods
How Your New Employer’s Plan Affects Marketplace Subsidies
If your new employer offers insurance, that offer can shut off your eligibility for Marketplace premium tax credits even if you’d rather keep a Marketplace plan. You generally cannot receive subsidies when the employer’s plan is both affordable and provides minimum value.
- Affordability. For plan years beginning in 2026, your employer’s plan counts as affordable if your share of the premium for self-only coverage is no more than 9.96 percent of household income.8Internal Revenue Service. Rev. Proc. 2025-25
- Minimum value. A plan provides minimum value if it covers at least 60 percent of the total expected cost of covered benefits.9Internal Revenue Service. 2HealthCare.gov. Health Care Coverage Options for Unemployed
What You Need to Enroll
For a Marketplace application, have Social Security numbers and dates of birth for everyone in your household who is applying.10Centers for Medicare & Medicaid Services. My Marketplace Application Checklist You also need your best estimate of annual household income for the plan year, since premium tax credits are based on projected Modified Adjusted Gross Income.11HealthCare.gov. How to Estimate Your Expected Income and Count Household Members A new salary makes the estimate harder and more important: underestimate and you may owe money back at tax time; overestimate and you may miss savings you were entitled to.
To confirm the special enrollment period, the Marketplace will ask for proof that your prior coverage ended and when.12HealthCare.gov. Send Documents to Confirm a Special Enrollment Period A termination letter from your old HR department or a notice from the prior insurer showing the final date of coverage usually works. If your new employer offers insurance, ask HR for a Summary of Benefits and Coverage so you can compare the employer plan against Marketplace options before choosing.
Applications go through HR or the benefits portal for an employer plan, or through your state exchange or HealthCare.gov for a Marketplace plan. Supporting documents can be uploaded to your Marketplace account or mailed to the processing center.12HealthCare.gov. Send Documents to Confirm a Special Enrollment Period Once the Marketplace verifies the qualifying event, your effective date follows the timing rules above, and your confirmation notice will include your policy number and instructions for the first premium payment.
