The recent government shutdown made one thing abundantly clear: health care affordability remains a flashpoint in Washington’s fiscal battles. At the center of the dispute was the fate of the Affordable Care Act’s (ACA) enhanced premium subsidies—temporary provisions that have helped millions of Americans afford coverage at a cost of about $30 billion per year, but are now set to expire. The Congressional Budget Office estimates that if these subsidies lapse, roughly 4 million people could be priced out of the ACA market and lose health insurance coverage. As Congress reconvenes, the question of whether and how to extend these subsidies will dominate policy conversations on Capitol Hill in the weeks ahead.
To understand what’s at stake in this debate, it helps to look at how the Affordable Care Act’s (ACA) premium tax credits are structured. The ACA offers Premium Tax Credits to make health insurance more affordable, but there are two versions. Standard credits apply only to households earning between 100% and 400% of the federal poverty level and the share of income you pay for an insurance plan increases with income ( from ~2% up to 9.5%). These credits are not set to expire and will remain in place.
By contrast, the enhanced credits (set to expire at the end of 2025) are more generous: they remove the 400% income cap and instead limit premiums to no more than 8.5% of household income, while also providing $0 premiums for the lowest‑income enrollees. If these enhanced credits expire, many families — especially those above the 400% threshold — will face steep increases in monthly insurance costs. The largest increases will be felt by older, middle-income Americans. For instance, an analysis of Kaiser Family Foundation data reported by CNN found that monthly premiums for people aged 60 with annual income of:
- $95,000, will double from just under $700 to almost $1,400;
- $65,000, will nearly triple from about $450 to almost $1,400.
Policy Options on the Table
Temporary Full Extension with No Offsets
The Senate Democratic Caucus has released a proposal to extend the enhanced subsidies for three years. A clean extension of the enhanced subsidy would cost about $30 billion per year. However, the Committee for a Responsible Federal Budget estimates that this proposal will cost $300 billion over three years due to the inclusion of additional provisions that increase the cost of the bill such as: permanently repealing provisions in the 2025 reconciliation law that eliminated subsidies for certain groups enrolling during special enrollment periods, requiring full repayments of overpayments of the advanced subsidies, and other program integrity measures. No offsets have been identified to pay for, or reduce, the cost of this proposal.
Another proposal, the Bipartisan Premium Tax Credit Extension Act, would extend the enhanced subsidies for one year at an estimated cost of $30 billion—with no offsets identified. Other bills extend for two or three years at roughly the same annual cost.
Temporary Extension with Lower Income Cut-Off and Offsets
Several compromise bills combine a temporary extension with limits on eligibility and offsets to cover the cost. The Fix It Act, a bipartisan proposal, would extend subsidies for two years but cap eligibility at six times the federal poverty line ($192,000 for a family of four). This reduces the two-year cost to $55 billion, $5 billion less than a full extension.
The bill also incorporates provisions from the No Upcode Act, which targets excessive Medicare Advantage overpayments by curbing insurers’ practice of “upcoding”—inflating diagnoses to secure higher reimbursements. By requiring the Centers for Medicare and Medicaid Services (CMS) to use two years of diagnostic data and exclude outdated diagnoses, the measure would reduce incentives for manipulation. According to the CBO, these reforms could save taxpayers about $124 billion over ten years. With these offsets, the Fix It Act could achieve a net deficit reduction of roughly $70 billion over the decade.
Alternative: Prefunded Flexible Spending Accounts (FSAs)
Republicans have floated an alternative approach: prefunded FSAs for ACA enrollees. Unlike subsidies, which reduce premium costs, FSAs would provide payments to individuals for health-related out-of-pocket expenses—excluding premiums. While details remain limited, the concept repurposes funds that would otherwise go to subsidies. The cost likely would be similar to extending the subsidies: about $30 billion per year, or more than $300 billion over ten years.
Understanding the Trade-Offs
The goal of improving health care affordability is widely shared, but the methods differ. With the national debt now at $38 trillion—larger than the entire U.S. economy—and deficits projected to exceed 6% of GDP for the foreseeable future, continuing to add to the debt will undermine affordability in other areas. The need to finance steeply rising government debt can drive up interest rates on mortgages, car loans, and credit cards. It also raises the risk of a debt-fueled economic crisis and reduces the government’s flexibility to respond to future downturns.
For these reasons, it is imperative that all policies be paid for. Otherwise, we only make our unsustainable debt problem worse.
Conclusion: The Bigger Picture
The debate over ACA enhanced subsidies is about more than health care—it’s about fiscal responsibility. Without offsets, even well-intentioned policies deepen the deficit challenge. The choices Congress makes will reveal whether policymakers are willing to pair new commitments with credible offsets, or whether short-term fixes will continue to undermine long-term fiscal sustainability.
For consumers, the outcome will determine not only the affordability of coverage but also the stability of the health care system they rely on. For the nation, it will signal whether leaders are prepared to confront the hard trade-offs between expanding benefits and maintaining fiscal discipline.
