How to Apply for ACA Insurance in Texas (2026 Guide)

If you qualify for the Affordable Care Act, here's how to apply for ACA insurance in Texas, where to go, and what to expect in 2026.

Start at HealthCare.gov. Texas doesn't run its own insurance marketplace, so it uses the federal one. That means every Texan who buys an ACA plan applies in the same place, HealthCare.gov. There's no separate Texas website to hunt for.

Open enrollment runs from November 1 through January 15 each year. But the date that matters most is December 15. If you want your coverage to start January 1, you have to pick a plan by December 15. Enroll between December 16 and January 15, and your coverage starts February 1 instead.

Missed that window? You still have options if your life changed. Losing job-based coverage, getting married, having a baby, or moving can open a Special Enrollment Period. You get 60 days from the date of that life event to enroll. Don't wait on it. That 60-day clock is firm.

Before you start the application, gather a few things so you're not stopped halfway through. You'll need your Social Security number, an estimate of your household income for the year, and information about any job-based insurance available to you or your family. One thing we watch closely: your income estimate isn't just paperwork. The premium tax credit is reconciled when you file your taxes. If you guess too low and end up earning more, you may have to pay some of it back. Guess too high, and you'll get the rest as a refund. A realistic estimate now saves a surprise next April.

You don't have to do this alone, and you don't have to pay anyone to help. Free, trained help is available across Texas through people called Navigators. On HealthCare.gov, use the "Find Local Help" tool and look for "Assisters." They give unbiased guidance at no cost. Unlike agents or brokers, they don't earn commissions and aren't tied to any one insurance company.

Now, about those savings. Here's the part that confuses a lot of people: there's no separate application for the subsidy. When you fill out the single HealthCare.gov application, the system calculates your savings automatically. It uses your household size and your estimated income to figure out your premium tax credit, the discount that lowers your monthly bill.

That credit doesn't come to you as a check. It goes straight to your insurance company each month, and you pay the difference. So if your plan costs $500 a month and your credit is $400, you pay $100. You'll never have to file a separate form to claim it.

One change you should know about for 2026. From 2021 through 2025, the federal government offered enhanced subsidies that made coverage cheaper for almost everyone and extended help to higher earners. Those enhanced subsidies expired at the end of 2025. For 2026, the income cutoff for federal subsidies is back to 400% of the federal poverty level (FPL), the standard line the program used for years.

Here's what that means in plain terms: if your income is below that 400% line, you still qualify for help. You'll just get it at the standard rate rather than the larger amounts of the past few years. The "subsidy cliff," where help cuts off above 400% of FPL, returned in 2026, according to healthinsurance.org's Texas marketplace guide. Most Texans who buy ACA coverage fall well under that line and still get real help.

How much help? More than you might expect. Across the roughly 4.2 million Texans who signed up for 2026 coverage, nearly 92% received premium subsidies, and those subsidies paid an average of $667 a month toward their premiums, according to healthinsurance.org's analysis of CMS data. After those subsidies, the average Texas enrollee paid about $89 a month for coverage.

There's a second kind of savings worth knowing about. If your household income falls between 100% and 250% of FPL, you may also qualify for cost-sharing reductions, which lower your deductible and your copays, the amounts you pay when you actually use care. But there's a catch: you only get them if you pick a Silver-level plan. Choose Bronze or Gold, and you leave that extra help on the table.

So here's your next step. Set aside about an hour, gather your Social Security number and income estimate, and start your application at HealthCare.gov. You can see if you qualify with Radar by Turnout.

Where do I apply for ACA insurance in Texas?

You apply at HealthCare.gov. Texas uses the federal marketplace instead of running its own, so HealthCare.gov is the one official place to enroll. You can apply online, or call the Marketplace Call Center at 1-800-318-2596 if you'd rather talk to a person. Free local help from Navigators is also available across the state. Your next step: have your Social Security number and income estimate ready before you begin.

When is open enrollment for 2026 coverage in Texas?

Open enrollment runs November 1 through January 15. To get coverage starting January 1, pick your plan by December 15. Enroll between December 16 and January 15, and coverage begins February 1. If you miss open enrollment but lose job-based coverage or have another qualifying life event, you have 60 days to enroll through a Special Enrollment Period. Don't let the 60-day window pass.

Do I have to apply separately for the subsidy?

No. There's no separate subsidy application. When you complete the standard HealthCare.gov application, the system calculates your premium tax credit automatically using your household size and income estimate. The credit goes straight to your insurer each month, and you pay the remaining balance. Your next step: enter an accurate income estimate so your credit is calculated correctly.

Did ACA subsidies go away for 2026?

No, but they changed. The enhanced subsidies in place from 2021 through 2025 expired at the end of 2025. For 2026, the income cutoff returned to 400% of the federal poverty level. If your income is under that line, you still qualify, just at standard rates instead of the expanded ones. Most Texas enrollees still receive substantial help. Your next step: apply and let HealthCare.gov calculate your exact amount.
