Missing the annual Open Enrollment window in Texas does not lock you out of health coverage for the rest of the year. If you have had a qualifying life event, such as losing job-based insurance, getting married, having a baby, or moving, you can enroll in or change a Healthcare.gov marketplace plan during a Special Enrollment Period (SEP). Texas uses the federal marketplace rather than running its own exchange, so every rule below applies the same whether you live in Houston, Dallas, San Antonio, El Paso, or a rural county in the Panhandle. Most qualifying events give you 60 days from the event date to enroll, and a major 2026 rule change eliminated the year-round monthly SEP that low-income households used to rely on, so timing matters more than it used to.
What Is a Special Enrollment Period?
A Special Enrollment Period is a window outside the standard annual Open Enrollment Period when you are allowed to sign up for, or change, a marketplace health plan. Open Enrollment for 2026 coverage ran from November 1, 2025, through January 15, 2026. The next Open Enrollment Period, for 2027 coverage, is expected to run November 1, 2026, through January 15, 2027. Outside those windows, the only way onto a Healthcare.gov plan is through an SEP triggered by a life change the marketplace recognizes.
For most Texas residents, the SEP window is 60 days. That clock generally starts on the date of the qualifying event, not the date you submit your application, so acting quickly matters. If you enroll in the first half of your 60-day window, coverage can often start the first day of the following month. Enroll later in the window and your start date gets pushed out further.
Qualifying Life Events That Trigger a Texas SEP
Healthcare.gov sorts qualifying events into four broad categories: loss of coverage, changes in household, changes in residence, and other special situations. Here is what applies in Texas.
Loss of Health Coverage
- Losing job-based health insurance through a layoff, reduced hours, or an employer dropping coverage
- Aging out of a parent's plan at 26
- Losing eligibility for Texas Medicaid or Texas CHIP
- Reaching the end of 12-month postpartum Medicaid coverage
- Losing coverage through a former spouse after a divorce
- Your individual market plan or COBRA continuation coverage ending
- Losing student health coverage after graduation
Changes in Household
- Getting married
- Getting divorced or legally separated and losing coverage as a result
- Having a baby, adopting a child, or receiving a child in foster placement
- A death in the family that changes your household's eligibility for a current plan
- Gaining a dependent through a court order or child support order
Changes in Residence
- Moving to Texas from another state
- Moving within Texas to a new county or ZIP code with different plan options
- A student moving to or from school in Texas
- A seasonal or agricultural worker moving into or out of the state
- Moving to or from a shelter or transitional housing
Other Qualifying Situations
- Gaining U.S. citizenship or lawfully present immigration status
- Leaving incarceration
- Becoming newly eligible for marketplace subsidies because your income changed and you no longer qualify for Texas Medicaid or CHIP
- AmeriCorps members starting or ending a term of service
- A serious medical condition, hurricane, wildfire, winter storm, or other emergency that prevented you from enrolling during Open Enrollment. This exceptional circumstance SEP is reviewed case by case and often follows a FEMA disaster declaration, which matters along the Texas Gulf Coast during hurricane season
- Certain plan-level problems, such as your insurer violating its contract or an enrollment error made by the marketplace
The Big 2026 Change: Low-Income Monthly SEP Is Gone
For several years, anyone with an estimated household income at or below 150% of the federal poverty level could enroll in a marketplace plan any month of the year, not just during Open Enrollment or a standard SEP. That monthly low-income SEP has been eliminated. Federal regulators finalized a permanent ban on it in 2026, so it is not returning next year.
This change hits Texas harder than most states. Texas has not expanded Medicaid, and the income cutoff for parents and caretaker relatives is one of the lowest in the country, roughly 14% to 18% of the federal poverty level depending on household size. Adults without dependent children generally cannot qualify for Texas Medicaid at all, no matter how little they earn. Before the rule change, Texans in the 100% to 150% FPL range who missed Open Enrollment still had a path to a marketplace plan almost any month. Now, without a separate qualifying event, they wait for the next annual window.
If your household income is genuinely below 100% of the federal poverty level and you do not fit a Texas Medicaid category, you likely fall into the coverage gap, which an estimated 617,000 or more Texans occupy. That gap is a separate problem from SEP eligibility. See our Texas benefits overview for the programs still open to you.
2026 Federal Poverty Level Reference
| Household Size | 100% FPL (annual) | 150% FPL (annual) | 400% FPL (annual) |
|---|
| 1 | $15,960 | $23,940 | $63,840 |
| 2 | $21,640 | $32,460 | $86,560 |
| 3 | $27,320 | $40,980 | $109,280 |
| 4 | $33,000 | $49,500 | $132,000 |
These figures determine your premium tax credit amount if you qualify for an SEP and enroll in a Texas marketplace plan. Most Texas enrollees between 100% and 400% FPL qualify for some level of premium subsidy. Texas carriers raised rates sharply for 2026, with an average individual market increase of roughly 33%, so the size of your tax credit matters more this year than it did last year.
How to Apply for a Texas SEP
- Confirm your qualifying event and its exact date. Write it down. This is what starts your 60-day clock.
- Gather documentation. Healthcare.gov typically asks for proof: a termination letter or COBRA notice for lost coverage, a marriage certificate, a birth certificate or adoption paperwork, a signed Texas lease or utility bill for a move, or a Texas Medicaid or CHIP denial or termination letter.
- Go to Healthcare.gov. Texas does not operate a state exchange, so all marketplace applications go through the federal site or by phone at 1-800-318-2596.
- Report your household income and size accurately. This sets your premium tax credit, and the amount is reconciled when you file your federal taxes.
- Select your qualifying event and upload documents. The system prompts you to describe the event and attach proof, usually within 30 days of starting the application.
- Compare plans. Look at monthly premium, deductible, prescription coverage, and provider network. Silver plans are the only tier eligible for cost-sharing reductions if your income qualifies, which lowers deductibles and copays.
- Pay your first premium. Coverage does not begin until the first payment clears, even after your application is approved.
- Confirm your coverage start date in writing. It depends on where in the 60-day window you enrolled.
Free help is available. CMS-certified navigators and licensed agents across Texas can walk you through documentation at no cost, and you can find one through the Find Local Help tool on Healthcare.gov or by calling 2-1-1 Texas.
SEP Coverage Start Dates
| When You Enroll | Typical Coverage Start Date |
|---|
| 1st through 15th of the month | 1st of the following month |
| 16th through end of month | 1st of the second following month |
| Birth, adoption, foster placement | Date of the event (retroactive) |
| Marriage | 1st of the month following plan selection |
Birth and adoption work differently from most events. Coverage can start on the actual date of birth or adoption even if you enroll a few weeks later, as long as you file within the 60-day window.
What Happens If You Miss the 60-Day Window
If you do not act within 60 days of a qualifying event, that SEP closes. You would then wait for the next Open Enrollment Period unless a new qualifying event occurs. There is no general hardship extension outside the narrow exceptional circumstances category, and getting approved under that category requires documentation of what prevented you from enrolling. Apply as soon as possible after a life change rather than near the deadline, since document review can take time.
Texas-Specific Notes
Texas has the largest marketplace population in the country outside of Florida, with more than 3 million plan selections for 2026 coverage, and roughly 16 insurers offering plans statewide. Carrier participation shifted for 2026, with Aetna exiting the Texas individual market after 2025 and Harbor Health entering, so if you are switching plans during an SEP, confirm your doctors and hospitals are still in network before you finalize.
The Texas Department of Insurance regulates the companies selling marketplace plans but does not process applications. Medicaid, CHIP, SNAP, and TANF applications go through YourTexasBenefits.com or 1-800-252-8263. If you are a woman who lost Medicaid coverage after a pregnancy, Healthy Texas Women may cover family planning and preventive services while you sort out marketplace enrollment. Because Texas has not expanded Medicaid, marketplace subsidies are often the only realistic route to affordable coverage for working adults without job-based insurance. If your household situation just changed and you are not sure whether you qualify for an SEP, Texas Medicaid, CHIP, or another assistance program, a free eligibility screening can sort it out in a few minutes.
Frequently Asked Questions
How long is the Texas Special Enrollment Period?
Most qualifying events give you 60 days from the date of the event to enroll in a marketplace plan through Healthcare.gov. Some events, including a known upcoming loss of coverage, also let you apply up to 60 days before the loss takes effect, which prevents a gap in coverage.
Does Texas still have a low-income SEP for people under 150% FPL?
No. The monthly special enrollment period for households at or below 150% of the federal poverty level has been eliminated and the ban was made permanent by federal rule in 2026. Households in that income range now need either the annual Open Enrollment Period or a separate qualifying event.
Can I get an SEP in Texas just because my income dropped?
Usually not on its own. An income change qualifies when it makes you newly eligible for premium tax credits or causes you to lose Texas Medicaid or CHIP eligibility. A drop in income with no change in program eligibility is generally not a standalone qualifying event.
Does a hurricane or winter storm count as a qualifying event in Texas?
It can. If a FEMA-declared disaster or a severe weather emergency prevented you from enrolling during Open Enrollment or during an SEP you already qualified for, you may be granted an exceptional circumstances SEP. These are reviewed individually, so call the Healthcare.gov marketplace at 1-800-318-2596 and explain what happened.
What documents do I need for a Texas SEP application?
It depends on the event. Common proof includes a job termination letter, a COBRA election or termination notice, a marriage certificate, a divorce decree, a birth or adoption certificate, a new Texas lease or utility bill, or a Texas Medicaid or CHIP denial or termination notice.
Can I switch plans during an SEP or only enroll for the first time?
If you already have marketplace coverage and experience a qualifying event, you can typically switch to a different plan, sometimes within the same metal tier and sometimes across tiers depending on the event. You are not limited to first-time enrollment.
What if I missed Open Enrollment and have no qualifying event?
Without a qualifying event, you generally cannot enroll in a Healthcare.gov plan until the next Open Enrollment Period. Depending on your income and household, you may still qualify for Texas Medicaid, CHIP for children under 19, Healthy Texas Women, or county indigent care programs in the meantime.
Does moving within Texas count as a qualifying event?
Yes, if the move gives you access to different plan options, such as relocating from Lubbock to Houston where different insurers operate. A move within the same service area that does not change your available plans generally does not qualify. You also have to prove you had qualifying coverage for at least one of the 60 days before the move, with limited exceptions.
When is the next Open Enrollment Period for Texas?
The next annual Open Enrollment Period is expected to run November 1, 2026, through January 15, 2027, for coverage effective in 2027. CMS confirms the exact dates closer to the fall.
