The "subsidy cliff" returned to the ACA marketplace in 2026, and it hit fast. Congress let the enhanced premium tax credits created by the American Rescue Plan and extended by the Inflation Reduction Act expire at the end of 2025. The result: marketplace premium payments jumped sharply for millions of people, and anyone with household income above 400% of the federal poverty level lost their subsidy altogether, no matter how expensive their plan is.
For small business owners, this is not just a headline. It changes the math on whether employees are better off buying their own coverage or getting it through work. This guide breaks down what changed, who it hits hardest, and what small employers can do about it.
What Is the ACA "Subsidy Cliff," and Why Did It Return in 2026?
The subsidy cliff is the point where ACA marketplace premium subsidies stop entirely once a household's income crosses 400% of the federal poverty level. Before 2021, this cliff was a normal part of the ACA. The American Rescue Plan removed it for 2021 and 2022, and the Inflation Reduction Act extended that removal through 2025, capping benchmark Silver plan premiums at 8.5% of income for higher earners instead of cutting them off completely.
Congress did not renew that extension for 2026. The cliff is back. According to KFF, the enhanced tax credits had driven ACA marketplace enrollment to record highs by expanding subsidy eligibility to people who earn well above 400% of the poverty line. Without them, that group now pays full price the moment they cross the threshold.
How Much Did ACA Marketplace Premiums Increase in 2026?
Marketplace premium payments increased sharply in 2026, and the size of the jump depends heavily on age, location, and income. KFF found that premium payments for subsidized enrollees rose 114% on average nationally to keep the same plan. Across the full marketplace population, including unsubsidized buyers, the average net monthly premium payment rose 58%, from $113 to $178, according to KFF's 2026 marketplace tracking.
The increase is far steeper for older buyers just above the 400% FPL line, since ACA premiums are age-rated and can run two to three times higher for someone in their 60s compared to a 21-year-old. healthinsurance.org documented a real-world example: a 63-year-old couple in Charleston, West Virginia earning $85,000 a year, just over the 400% FPL threshold, paid about $300 a month for the lowest-cost Gold plan in 2025. In 2026, with no subsidy at all, the same plan costs $4,562 a month. Their lowest-cost Bronze plan went from $0 a month to $3,648 a month.
States with higher baseline premiums saw the sharpest percentage jumps. KFF's Peterson-KFF Health System Tracker flagged Alaska, Delaware, Maine, Mississippi, Nebraska, Tennessee, Vermont, Wisconsin, West Virginia, and Wyoming as having the highest projected full-price marketplace premiums for 2026, which means buyers in those states who lose their subsidy face the largest dollar increases.

Who Is Most Affected by the Subsidy Cliff?
The subsidy cliff hits hardest for people between roughly 50 and 64 years old with household income just above 400% of the federal poverty level, which was $84,600 for a household of two using 2025 guidelines. This group is old enough to pay the highest ACA age-rated premiums but too young for Medicare, and they no longer qualify for any subsidy once they cross the income line. According to CMS enrollment data cited by KFF, the share of marketplace enrollees receiving a premium tax credit fell from 92% in 2025 to 87% in 2026, the first drop in subsidized enrollment since 2020. KFF also projects that average monthly marketplace enrollment could fall to about 17.5 million people in 2026, down from 22.3 million in 2025, as some buyers drop coverage entirely rather than pay full price.
Small business owners and self-employed individuals who buy their own marketplace coverage are directly exposed to this cliff, since their income often sits in the affected range. Employees of small businesses that do not offer group coverage face the same exposure.
Does the Subsidy Cliff Affect Employer-Sponsored Health Coverage?
No. The subsidy cliff only applies to individual marketplace plans purchased through healthcare.gov or a state exchange. It has no effect on the price or availability of employer-sponsored group health coverage. This is one of the clearest changes in the relative value of employer coverage for 2026: a plan that used to compete against a subsidized $300-a-month marketplace option now competes against a $3,600-plus unsubsidized one for employees over 400% of FPL. Group coverage was already exempt from the ACA's individual affordability calculations, and that gap has only widened.
This also raises the stakes for how employees pay for whatever coverage they do have. A Section 125 cafeteria plan lets employees pay their share of group premiums with pre-tax payroll dollars, which lowers their taxable income and reduces the employer's FICA obligation at the same time. Read Summit's <a href="/blog/section-125-cafeteria-plan-2026-guide">complete guide to Section 125 cafeteria plans</a> for the full mechanics.
How Can Small Business Employers Help Employees Avoid the Subsidy Cliff?
Small employers have three practical paths in 2026. First, offer a traditional group health plan through a Section 125 Premium Only Plan, which sidesteps the marketplace and its subsidy cliff entirely while cutting payroll taxes for both sides. Second, offer an Individual Coverage Health Reimbursement Arrangement, or ICHRA, which lets the employer set a fixed reimbursement amount toward an employee's individual marketplace plan. An ICHRA contribution is not means-tested and does not disappear at 400% of FPL, so it can meaningfully offset the subsidy cliff for affected employees. See Summit's guide to <a href="/blog/how-does-ichra-work">how ICHRA works</a> for a full breakdown. Third, layer in a zero-cost supplemental benefit stack, virtual urgent care, $0 primary care visits, and discounted prescriptions, on top of whatever core coverage employees choose, which softens the blow for anyone still absorbing a bigger premium bill.
For businesses that are not ready to sponsor a full group plan, Summit's guide to <a href="/blog/small-business-health-insurance-alternatives-2026">small business health insurance alternatives</a> and <a href="/blog/zero-cost-employee-health-benefits-2026">zero-cost employee health benefits</a> covers lower-commitment options that still give employees something real to work with.
Is a Section 125 Plan Still Worth It If Employees Don't Buy Marketplace Coverage?
Yes. A Section 125 plan's value does not depend on the marketplace at all. It comes from the FICA and income tax savings generated whenever an employee pays for an eligible benefit with pre-tax payroll dollars, whether that benefit is a group health premium, an FSA contribution, or a supplemental plan. Summit Health Benefits charges $35 per enrolled employee per month to administer a plan. Employers typically recapture $91 to $136 per enrolled employee per month in employer-side FICA savings alone, for a net benefit of $56 to $101 per employee per month after the admin fee, while employees see $70 to $110 more in take-home pay each month. None of that math changes based on what happens to ACA marketplace subsidies. See the full breakdown in Summit's guide to <a href="/blog/maximizing-fica-tax-savings">maximizing FICA tax savings</a>.
For a 10-person business with $400 a month in employee pre-tax premium contributions, the employer avoids roughly $306 a month in FICA taxes ($4,000 x 7.65%), or $3,672 a year. Against a $4,200 annual admin fee for that group, the math still works because the FICA savings are only one part of the value. Employees keep more of every paycheck regardless of what is happening at healthcare.gov.
