The ACA “Family Glitch” Fix: Can Houston Families Get Subsidies When a Spouse Has Job Coverage? (2026)

Picture a kitchen table in Spring, Texas, on an October evening. A nurse who works for a Houston hospital system has just printed her open-enrollment packet. The number that jumps out is the one for her: her own job-based health plan, just for herself, costs her about $130 a month — manageable. Then her eyes drop to the next line. Adding her husband and their two kids pushes the family premium to roughly $1,300 a month, more than a third of the household’s take-home pay. The plan is “affordable” for her on paper, but pricing the whole family into it would mean cutting groceries, the car payment, or the kids’ soccer fees. For years, families exactly like this one were told they did not qualify for any help on the Marketplace — because the rules looked only at the cost of her coverage, never the family’s. That was the infamous “family glitch.”

If you are a working parent in Katy, Pasadena, Cypress, or anywhere across Harris County staring at the same math, here is the direct answer you came for: since the 2023 plan year, your family members’ eligibility for Marketplace premium tax credits is judged on the cost of FAMILY job coverage, not just the worker’s self-only cost. The IRS finalized the rule in October 2022, and it has been live every year since — including the 2026 plan year you are enrolled in right now. That single change means many Houston families who were locked out can now qualify for subsidies on a Marketplace plan for the spouse and children, even when one parent is offered job-based insurance.

There is a catch worth knowing up front, and we will spend real time on it below: the fix changed the rule for the worker’s family members, but it did not change the rule for the worker. The employee’s own affordability is still measured against self-only cost. So in many Houston households the family qualifies for Marketplace help while the employee themselves does not — the “split family” outcome. This guide walks through exactly how the math works, what the 2026 numbers are, and how Wise Insurance Agency helps Harris County families run their own numbers.

What the “family glitch” was — and who it trapped

To understand why the fix matters, you have to understand the trap it replaced. The Affordable Care Act says that if you are offered job-based health coverage that counts as “affordable,” you and your family generally cannot get premium tax credits to buy a Marketplace plan instead. Fair enough — the law does not want to subsidize people who already have an affordable offer at work.

The problem was in one word: affordable. Back in 2013, the IRS interpreted the statute to mean that affordability would be measured against the cost of self-only coverage — the price for the employee alone. If the worker’s individual premium was below the threshold, the entire family was deemed to have an affordable offer, even when the cost to actually cover the family was wildly higher. Employers commonly subsidize the worker’s premium heavily but pass most of the family-tier cost to the employee. So a worker might pay $130 a month for themselves and $1,300 a month to add a spouse and children — and under the old rule, that family was still locked out of Marketplace subsidies.

That gap had a name and a size. The Kaiser Family Foundation estimated that roughly 5.1 million people fell into the family glitch. These were not high earners gaming the system. They were nurses, restaurant workers, warehouse staff, teachers’ aides, and small-business employees across places like Houston whose jobs offered single coverage that was affordable on paper but family coverage that ate an unworkable share of the budget.

Families caught in the glitch had three bad choices: stretch to buy expensive family coverage at work, leave the spouse and kids uninsured, or buy a full-price Marketplace plan with zero help. For background on how Marketplace coverage fits the bigger picture, see our overview of health insurance and ACA health insurance plans.

The IRS fix: how the rule changed in 2023

In October 2022, the IRS finalized a regulation that rewrote that 2013 interpretation. Effective for the 2023 plan year and every year since, affordability for an employee’s family members is now measured against the cost of family coverage at the job — not the worker’s self-only premium. The full final rule and its background are documented by the Treasury Department and explained in plain language at healthinsurance.org’s family-glitch explainer; KFF’s policy analysis sits at KFF — Navigating the Family Glitch Fix.

In practical terms, the new rule says this: if the amount the worker would have to pay to enroll the whole family in the job plan is more than the affordability percentage of household income, then the job’s family coverage is “unaffordable” for the family members — and the spouse and children become eligible to apply for premium tax credits on the Marketplace.

The IRS itself projected wide variation in how many people this would help: the agency estimated somewhere between 600,000 and 2.3 million newly eligible people would enroll, with the Treasury Department’s working estimate around 1 million people gaining subsidized Marketplace coverage. That number is lower than the 5.1 million in the glitch because many families still find it simpler to keep everyone on one job plan — but for the families where the family-tier cost is genuinely punishing, the fix opened a door that had been bolted shut for a decade.

The exact mechanics — two affordability tests, one household

This is the heart of the matter, and it is where most families get confused. After the fix, your household effectively gets run through two separate affordability tests, and the results can disagree:

1. The employee test (self-only cost). Is the cost for the worker to cover just themselves at the job below the affordability threshold? If yes, the worker has an affordable offer and is not eligible for a premium tax credit. This part of the rule did not change.
2. The family-members test (family cost). Is the cost for the worker to cover the whole family at the job above the affordability threshold? If yes, the family coverage is unaffordable, and the family members — spouse and dependents — may qualify for a premium tax credit on the Marketplace.

Because the two tests use different price tags (self-only vs. family), they frequently land on opposite sides of the line. As KFF explains, “there is now a separate affordability determination for the employee and for family members,” so coverage “could be considered affordable for the employee but not for family members.” When that happens, the family members can get subsidized Marketplace coverage while the employee stays on the job plan. That is the split family result, and it is the single most important concept in this whole topic.

The chart below shows the structure visually — one offer, two tests, two possible doors:

The 2026 affordability threshold (9.96%) and how the math runs

“Affordable” is not a feeling — it is a specific percentage of household income that the IRS resets every year. For the 2026 plan year, the IRS set the affordability percentage at 9.96%, announced in Revenue Procedure 2025-25 in July 2025. That is the highest the threshold has ever been, and a notable jump from 9.02% in 2025. You can read the IRS document directly at IRS Rev. Proc. 2025-25 (PDF).

Here is how the percentage works in both directions:

• For the employee test: if the annual cost of self-only job coverage is more than 9.96% of household income, the worker’s own offer is unaffordable and the worker may qualify for a premium tax credit.
• For the family-members test: if the annual cost of family job coverage is more than 9.96% of household income, the family coverage is unaffordable and the spouse and children may qualify for a premium tax credit.

The table below shows how the recent threshold has moved. A higher percentage means coverage has to cost more before it is deemed “unaffordable,” so the threshold trend matters for whether your family clears the bar:

The chart below puts those four years side by side so you can see the trajectory at a glance:

How premium tax credits work on the Marketplace

If your family clears the unaffordability bar and qualifies, the help comes in the form of a premium tax credit (PTC) — a subsidy that lowers what you pay for a Marketplace plan. The credit is tied to your household income relative to the federal poverty level (FPL), and to the cost of a benchmark plan in your area. The lower your income within the eligible range, the larger the credit. The credit can be paid in advance directly to your insurer each month (lowering your bill) or claimed when you file taxes.

A few realities to keep front of mind for 2026:

• The income range matters. The temporary enhanced premium tax credits that ran from 2021 through 2025 expired at the end of 2025. For 2026, the upper income cliff has returned: households above 400% of the federal poverty level are generally not eligible for a premium tax credit. For reference, 400% FPL in 2026 is roughly $84,600 for a two-person household and $128,600 for a family of four.
• You apply as a tax household. Your eligibility is based on your projected household income for the coverage year and your tax-filing status.
• The family-glitch door is what gets you to the application. Without the fix, an affordable self-only offer would have disqualified the whole household. With the fix, the unaffordable family-tier cost is what makes the spouse and kids eligible to apply in the first place.

Because the enhanced subsidies sunset and the income cliff returned, 2026 is a year where running the actual numbers — not assumptions — is essential. A family that qualified comfortably in 2024 or 2025 may face a different result in 2026, and vice versa. This is exactly the kind of comparison our team runs with families at our Houston offices.

How to check if your family qualifies — step by step

You can get a strong read on your own situation with a calculator, your latest pay stub, and your employer’s benefits summary. Here is the sequence we use:

1. Find the family premium your employer would charge. Pull up your benefits portal or open-enrollment packet and locate the monthly amount you would pay to cover your whole family (employee + spouse + children) on the lowest-cost plan that meets minimum value. This is your premium for family coverage — not the self-only number.
2. Annualize it. Multiply that monthly family premium by 12.
3. Estimate household income. Use your projected total household income for the coverage year (wages, self-employment, and other taxable income for everyone on the tax return).
4. Run the percentage. Divide the annual family premium by household income. If the result is more than 9.96% (the 2026 threshold), the family coverage is unaffordable — your spouse and children may qualify for a premium tax credit.
5. Confirm the income range. Check whether your household income is within the eligible range (below the 400% FPL cliff for 2026). If both the affordability test and the income test point the right way, you likely have a real opportunity.
6. Compare total cost, not just the test. Qualifying does not automatically mean switching is the right move. Add up the real-world cost of the split-family arrangement — two premiums, two deductibles, two networks — versus keeping everyone on the job plan.

Step six is where many families need a second set of eyes, because the least expensive premium is not always the lowest total cost once deductibles and networks are in the picture. If you also have employer coverage questions on the company side, our employer health insurance plans page covers that angle, and families weighing public-program options can review Medicare vs. Medicaid for context.

A Houston worked example, with dollar figures

Let’s run the nurse from Spring through the actual math. These numbers are illustrative — your real figures come from your own benefits packet and tax situation — but they show how the test works.

The household: Maria and her husband Daniel live in Spring with two children. Maria works for a Houston-area hospital system. Their projected 2026 household income is $72,000.

What the job offers:

• Self-only coverage for Maria: $130/month → $1,560 per year.
• Family coverage (Maria + Daniel + 2 kids): $1,300/month → $15,600 per year.

Test 1 — the employee (self-only): $1,560 ÷ $72,000 = 2.2%. That is well below 9.96%, so Maria’s own coverage is affordable. Maria is not eligible for a premium tax credit. She keeps her job plan.

Test 2 — the family members (family cost): $15,600 ÷ $72,000 = 21.7%. That is far above the 9.96% threshold, so the family coverage is unaffordable. Daniel and the two children may qualify for premium tax credits on the Marketplace — provided the household income fits within the eligible range (it does, comfortably under the 400% FPL cliff for a family of four).

The result is a textbook split family: Maria stays on her affordable self-only job plan; Daniel and the kids apply for a subsidized Marketplace plan. Before the 2023 fix, all four of them would have been locked out of subsidies because Maria’s $130 self-only premium made the whole family “affordable” on paper.

The donut below shows how punishing the family-tier cost would be relative to this household’s income — the share of income the full family premium would consume:

The catch: split families, no double-dipping, and the trade-offs

The fix is a genuine win for families like Maria’s, but it comes with real fine print. Understanding it prevents costly mistakes.

The employee usually still cannot get a subsidy

The fix changed the rule for family members, not for the worker. If self-only coverage is affordable, the employee remains ineligible for a premium tax credit — period. If the employee chose to drop the job plan and join the family on a Marketplace plan, their share of that Marketplace premium would not be subsidized, because they had an affordable self-only offer. That is why the worker typically stays put on the job plan.

No double-dipping

You cannot be enrolled in job-based coverage and collect a premium tax credit for the same person at the same time. A family member who is actually enrolled in the affordable job plan is not eligible for a subsidy. The subsidy is for family members who are declining the unaffordable family job coverage and buying on the Marketplace instead. And a worker who accepts the unaffordable family coverage at work cannot then also claim Marketplace credits for those same family members.

Split families mean two of everything

A split arrangement — worker on the job plan, spouse and kids on a Marketplace plan — means two separate premiums, two deductibles, two out-of-pocket maximums, and potentially two different provider networks. For some families the subsidized Marketplace premium more than makes up for the added complexity; for others, especially those who want everyone seeing the same doctors under one deductible, keeping the family together on one plan is the better call even without a subsidy. There is no universal answer — it depends on your numbers and your doctors.

Your next step and the enrollment calendar

Timing is everything with the Marketplace, because you can usually only enroll during specific windows.

• Open Enrollment for 2027 coverage: In most states, including Texas, Open Enrollment runs November 1 – December 15, 2026, with coverage effective January 1, 2027. This is the main window to set up a split-family arrangement for next year.
• Special Enrollment Periods (SEPs): Outside Open Enrollment, you generally need a qualifying life event — marriage, the birth or adoption of a child, a move, or a loss of other coverage — to enroll mid-year. If your family’s job coverage situation changes (for example, the employer’s family premium jumps and crosses the affordability line), that can open a path; the exact SEP rules are specific, which is where guidance helps.
• Mid-year reviews: Even if you are mid-plan-year now, it is worth running the 2026 numbers so you know your position heading into the fall enrollment window.

The single most valuable thing you can do is get your own family’s two affordability tests calculated correctly with your real benefits figures and projected income — and then compare the true total cost of a split arrangement against keeping everyone together. That is precisely the help Wise Insurance Agency provides for families across Houston and Harris County, from our North Houston office to our South Houston office.
