Small Business Strategy

Denise runs a one-person graphic design studio out of her home near Wilmington. No employer, no group health plan, no HR department, just a laptop, a handful of steady clients, and a health insurance bill she pays herself every month through the ACA marketplace. When her 2026 renewal notice landed, the number made her stop and reread it twice. Her premium had jumped by more than half. Nothing about her health, her income, or her plan had changed.

Denise is not an edge case. Roughly 2.6 million people dropped their ACA marketplace coverage between February 2025 and February 2026, a 12 percent decline and the steepest single-year drop since the marketplaces opened in 2014, and the people who kept their coverage saw premiums rise by 58 percent on average (Fortune, 2026). That did not happen because insurance got more expensive to provide. It happened because of a specific, traceable decision in Washington.

What Actually Happened in Washington

Since 2021, the federal government has offered enhanced premium tax credits that significantly lower what people pay for ACA marketplace coverage, especially for middle-income households who previously got little or no help (CBPP, 2025). Those enhanced credits were always scheduled to expire on December 31, 2025, unless Congress voted to extend them.

Extending them became one of the central demands behind the government shutdown that ran from October into November of 2025, the longest in U.S. history. The Senate passed a deal on November 10, 2025, and the shutdown officially ended once the House passed it and President Trump signed it into law on November 12, after Senate Republicans agreed to hold a vote on extending the credits the following month in exchange for enough Democratic votes to reopen the government (ASTHO, 2026).

That promised vote happened on December 11, 2025. The Senate considered two competing bills: a straightforward three-year extension from Democrats, and a Republican alternative built around health savings account contributions and cheaper, high-deductible plans instead of the existing credit structure. Neither bill reached the 60 votes needed to pass (WTW, 2025). Six days later, the House passed its own health care bill addressing other cost issues, but it did not include an extension either (WTW, 2025). The enhanced credits expired on schedule at the end of the year.

The story did not end there. On January 8, 2026, seventeen House Republicans broke with their own leadership and joined Democrats to pass a three-year extension, 230 to 196, after a discharge petition forced the bill onto the floor over leadership’s objections (ABC News, 2026; ASTHO, 2026). That bill has been sitting in the Senate ever since. As of this week, heading into the open enrollment period that starts November 1, it still has not been brought up for a vote (BenefitChamps, 2026).

Why This Wasn’t a Fight Between Two Equal Solutions

It is worth being direct about the political arithmetic here. Republicans held the House, the Senate, and the presidency throughout this entire fight. A party with unified control of all three branches of the federal government does not need an opposing party’s agreement to pass a bill, it needs its own leadership willing to schedule the vote. When the enhanced credits lapsed on December 31, 2025, that was not two sides pulling with equal leverage and landing at a stalemate. It was Republican leadership choosing not to bring a clean extension to the floor in December, and then, after a bipartisan House majority forced one through anyway in January, Senate Republican leadership choosing not to bring that bill up for a vote either (ASTHO, 2026).

The alternative Republicans offered in place of a clean extension was not a comparable substitute, and the numbers make that case without needing editorializing. The proposed HSA deposits ran 1,000 to 1,500 dollars a year, while the average deductible on the bronze and catastrophic plans those dollars were meant to pair with sat near 7,500 dollars for 2026, five to seven times larger than the deposit itself (Center for American Progress, 2025). Research on HSA expansions more broadly has found they do little to reduce what people actually spend on health care, and that the tax benefit flows overwhelmingly to higher earners: a household earning 800,000 dollars saves 37 cents for every HSA dollar contributed, compared to 12 cents for a household earning 30,000 dollars, while only about 4 percent of the total benefit reaches households earning 50,000 dollars or less (CBPP, 2025). The Congressional Budget Office has estimated that an HSA expansion along these lines would cost roughly 180 billion dollars over ten years, enough, by comparison, to have funded the enhanced premium tax credits Republicans let expire for roughly six more years (CBPP, 2025).

None of this is abstract for the people actually affected. More than 40 percent of American households do not have enough in savings to cover a typical private insurance deductible at all (Peterson-KFF Health System Tracker, 2025). A plan built around a high deductible is not functioning coverage for a household that cannot pay that deductible when something happens. For a small business owner managing their own insurance, this was never a close call between two reasonable paths forward. It was a choice between a real extension and an alternative that, on its own published numbers, could not do what it claimed to do.

What This Is Actually Costing People

The math behind this is not abstract. The Kaiser Family Foundation estimated that letting the enhanced credits expire would roughly double what a subsidized enrollee pays out of pocket for premiums, from an average of 888 dollars a year to 1,904 dollars, a 114 percent increase (KFF, 2025). That estimate held up. By mid-2026, people who kept their coverage were paying 58 percent more on average, with deductibles up 37 percent, more than 1,000 dollars per person (Fortune, 2026).

And the next round is already forming. Insurers have filed for a median premium increase of roughly 15 percent for 2027, on top of the much higher baseline that is already in place, as open enrollment approaches on November 1 (BenefitChamps, 2026).

Why This Lands Especially Hard on Small Business Owners

This is not a policy story happening to someone else’s industry. About half of the adults with ACA marketplace coverage are small business owners, people employed by small businesses, or self-employed individuals like Denise (KFF, 2026). For a firm like Muninn’s own client base, this is less a national headline and more a direct line item.

An employee at a large company has a group health plan and an HR department managing the renewal behind the scenes. A small business owner buying individual coverage on the marketplace has neither. The decision of whether to keep full coverage, downgrade to a high-deductible plan, or go without falls entirely on the owner, with real consequences for their own health and for the business if something goes wrong. When an owner also covers even a few employees through individual marketplace plans rather than a group policy, the same increase applies to each person covered, pulled straight out of operating cash flow with no large-employer leverage to soften it.

What to Do Before November 1

A few things are worth doing now rather than waiting for the renewal notice to arrive. Compare marketplace plans carefully during open enrollment instead of letting a plan auto-renew, since networks and prices shift every year. Talk to a licensed health insurance broker, a service that costs nothing out of pocket since brokers are paid by the insurers, rather than navigating the marketplace alone. If self-employed, sit down with a tax professional to look at whether an HSA-eligible high-deductible plan paired with the self-employed health insurance deduction changes the math, since the right answer depends on individual numbers, not a general rule. And build the likely increase into next year’s budget now, rather than being surprised by it in January. The House-passed extension is still technically alive in the Senate, so this is also worth watching, not treating as settled.

The Bottom Line

The premium increase hitting small business owners and the self-employed right now did not have to happen. Republicans held the House, Senate, and White House throughout this fight, and the alternative offered in place of a clean extension was not a serious substitute by its own numbers: an offset a fraction of the deductible it was meant to cover, a benefit structure that favors higher earners, and a cost roughly equivalent to years of the credits it replaced. The dollar impact is large, it is already showing up in real coverage losses, and it falls disproportionately on people who buy their own coverage rather than getting it through a large employer. Planning around it now, deliberately, is a better position than waiting on a fix that unified Republican control has so far chosen not to deliver.

Small Business Strategy

Consider a solo practitioner, a consultant, designer, or tradesperson operating without employees, who purchases individual health coverage through the ACA marketplace rather than through an employer group plan. That individual’s premium cost has moved in direct response to a congressional standoff with no bearing on her health status, her income, or the insurance product itself. This is the defining feature of the current premium shock: it is a policy-transmission event, not a market event, and its mechanism is traceable to specific, dated legislative decisions rather than to underlying cost-of-care trends.

I. The Legislative Timeline

Enhanced premium tax credits, which lower what ACA marketplace enrollees pay out of pocket relative to the law’s original, unenhanced subsidy structure, have been in effect since 2021 and were always scheduled to expire December 31, 2025, absent congressional action (CBPP, 2025). Extension of these credits became a central demand in the government shutdown that ran from early October into November of 2025, the longest shutdown in U.S. history. The Senate passed a deal on November 10, 2025, and the shutdown officially ended when the House passed it and President Trump signed it into law on November 12, on the strength of a negotiated commitment: Senate Republican leadership agreed to schedule a vote on credit extension the following month in exchange for the Democratic votes needed to reopen the government (ASTHO, 2026).

That vote occurred December 11, 2025. The Senate considered two mutually exclusive proposals, a Democratic bill providing a straightforward three-year extension and a Republican alternative restructuring assistance around health savings account contributions and expanded access to lower-cost, high-deductible plans. Neither secured the 60 votes required for passage (WTW, 2025). A separate House-passed bill six days later addressed adjacent health cost issues without extending the credits (WTW, 2025), and the enhanced credits lapsed on schedule.

A second legislative attempt followed in the new year. On January 8, 2026, a bipartisan House majority, including seventeen Republicans who broke from leadership, passed a three-year extension by a vote of 230 to 196, after a discharge petition forced floor consideration over leadership’s objection (ABC News, 2026; ASTHO, 2026). That bill remains pending in the Senate without a scheduled vote as of this writing, with the 2027 open enrollment period beginning November 1 (BenefitChamps, 2026).

II. Why This Was Not a Negotiation Between Comparable Alternatives

The deadlock should not be read as two parties advancing equally viable, equally funded proposals and failing to find common ground. Republicans held unified control of the House, Senate, and presidency throughout this period. Passage required only that Republican leadership schedule a vote on legislation its own membership could support, not that it secure agreement from an opposing party holding comparable institutional leverage. When Senate leadership declined to advance the bipartisan, House-passed three-year extension after January 8, 2026, that was an exercise of majority control over the legislative calendar, not an impasse between evenly matched negotiating positions (ASTHO, 2026).

The structural adequacy of the Republican alternative is measurable rather than a matter of framing. Proposed HSA contributions of 1,000 to 1,500 dollars annually were paired with eligibility restricted to bronze and catastrophic plans carrying an average 2026 deductible near 7,500 dollars, a five-to-sevenfold gap between the proposed offset and the out-of-pocket exposure it was meant to cover (Center for American Progress, 2025). Independent analysis of HSA expansion more broadly finds the design does not reduce aggregate health spending, concentrates its tax benefit among higher earners (a household earning 800,000 dollars realizes 37 cents of benefit per contributed dollar, versus 12 cents for a household earning 30,000 dollars, with only approximately 4 percent of total benefit reaching households at or below 50,000 dollars), and carries a projected cost of approximately 180 billion dollars over ten years, a sum comparable to roughly six years of the enhanced premium tax credits it was proposed in place of (CBPP, 2025).

This matters beyond its distributional profile, because a high-deductible structure’s practical value depends on a household’s capacity to pay the deductible when a claim arises. More than 40 percent of American households lack sufficient savings to cover a typical private insurance deductible (Peterson-KFF Health System Tracker, 2025), which functionally converts a high-deductible plan into underinsurance for a substantial share of the population it is proposed to serve. On this basis, the two proposals under consideration in December 2025 were not comparably serious policy instruments, regardless of how the dispute was characterized procedurally at the time.

III. The Premium Shock, Quantified

The Kaiser Family Foundation’s pre-expiration modeling estimated that letting the enhanced credits lapse would raise average out-of-pocket premium payments for subsidized enrollees by 114 percent, from 888 dollars to 1,904 dollars annually (KFF, 2025). Realized outcomes through mid-2026 tracked closely with that projection. Marketplace enrollment fell by 2.6 million people, a 12 percent decline and the steepest single-year drop since the exchanges opened in 2014, while enrollees who retained coverage absorbed a 58 percent average premium increase and a 37 percent increase in deductibles, more than 1,000 dollars per person (Fortune, 2026). A further increase is already filed for 2027: insurers have requested a median premium increase of approximately 15 percent on top of the current, already-elevated baseline, with open enrollment beginning November 1, 2026 (BenefitChamps, 2026).

IV. The Small Business Exposure Channel

This cost shock is not evenly distributed across the economy. Approximately half of adults holding ACA marketplace coverage are small business owners, employees of small businesses, or self-employed individuals (KFF, 2026), a population that, by definition, lacks access to the large-group employer plans that insulate most corporate employees from this specific exposure. The structural distinction matters: an owner or sole proprietor purchasing individual coverage bears the full premium increase directly, with no employer-side risk pooling, no benefits administration function managing the renewal, and no scale-based negotiating leverage. Where an owner also provides or subsidizes individual-market coverage for a small number of employees rather than a group policy, the increase compounds per covered person, drawn directly from operating cash flow rather than absorbed within a larger benefits budget.

V. Practical Implications for Owners

Several operating adjustments follow directly from the above. First, the 2027 premium increase should be modeled into budgeting now, prior to the November 1 renewal cycle, rather than treated as a January surprise. Second, active comparison shopping during open enrollment, rather than default auto-renewal, is warranted given that plan networks and pricing shift annually and the broker channel carries no direct cost to the enrollee. Third, self-employed owners should evaluate, with a tax professional, whether an HSA-eligible high-deductible plan paired with the self-employed health insurance deduction changes their effective cost exposure, since the answer is individual-specific rather than general. Fourth, the pending Senate-side extension bill remains live and merits monitoring, since its passage would materially change this analysis for the 2027 plan year.

VI. The Bottom Line

The premium increase now facing small business owners and self-employed individuals was not the inevitable output of two competing, comparably serious proposals failing to reconcile. Republicans held unified control of the House, Senate, and presidency throughout the relevant period, and the alternative offered in place of a clean extension does not hold up as a comparable substitute once measured against its own published numbers: an offset a fraction of the deductible it was paired with, a benefit structure concentrated among higher earners, and a cost roughly equivalent to several years of the credits it replaced. The magnitude of the resulting cost shock is large, the realized coverage losses already confirm the pre-expiration modeling, and the burden falls disproportionately on the population that buys coverage individually, a population that substantially overlaps with the small business sector itself. Owners who model this cost deliberately, rather than waiting on a legislative fix that unified Republican control has so far chosen not to deliver, are better positioned for an outcome that remains unresolved by choice rather than by necessity.
