Recent changes to ACA subsidies under Biden administration 2023
Executive summary
The Biden administration expanded and preserved “enhanced” ACA premium tax credits first created in 2021, and those enhancements were extended through 2025 by subsequent legislation — producing record marketplace enrollment and much larger federal subsidy costs (estimates: roughly $92 billion in 2023 rising toward ~$138 billion in 2025) [1] [2]. Policymakers, insurers and analysts now warn those enhanced credits are set to expire at the end of 2025 unless Congress acts, which would sharply raise net premiums for millions and re-create the old “subsidy cliff” above 400% of the federal poverty level [3] [4] [5].
1. What changed under the Biden administration: bigger, broader premium tax credits
The Biden administration’s COVID-era policy (ARPA 2021) widened eligibility and increased subsidy generosity through “reduced applicable percentages and eliminated indexing,” meaning more households qualified and existing recipients received larger credits; Congress then extended those enhancements for tax years 2023–2025 in FY2022 reconciliation [2] [6]. The net effect: larger federal subsidies and higher enrollment on marketplaces compared with pre-2021 rules [7] [1].
2. How the policy is delivered and why costs rose
ACA premium tax credits are paid to insurers throughout the year and reconciled on tax returns; expanding eligibility and raising subsidy amounts drives federal outlays. Federal subsidies grew from about $18 billion in 2014 to $92 billion by 2023 and were projected to reach roughly $138 billion by 2025, reflecting both rising enrollment and more generous subsidies [1]. Independent analyses find the enhanced credits kept average out-of-pocket premiums unusually low in 2024–25 [8].
3. Practical impacts for consumers: more coverage, lower premiums — for now
Enhanced credits produced record sign‑ups and made many plans effectively free for low- and middle-income enrollees; KFF and others tie the expansion to increased take-up and lowered net premiums in 2023–2025 [7] [8]. State- and federal-marketplace shoppers saw increased availability of $0-premium options and greater affordability relative to pre-enhancement years [4].
4. The looming expiration: a 2026 “subsidy cliff” if Congress does nothing
Under current law the enhanced premium tax credits expire after 2025 and subsidy calculations would revert to the pre‑enhancement (ACA-only) rules in 2026 unless Congress extends them; analysts warn average net premiums could more than double for subsidized enrollees if enhancements lapse [9] [4]. Estimates put roughly 22 million enrollees benefiting from enhanced credits — many face material premium jumps and return of the abrupt eligibility cutoff above 400% FPL [3] [5].
5. Politics and budget tradeoffs: extension debates and cost estimates
Extending the enhanced credits has been politically contested: Democrats have pushed for extensions while many Republicans oppose open‑ended extensions and raise concerns about cost, fraud and market distortions [10] [11]. Nonpartisan budget analysts and Congressional reports quantify extension costs: the 2022 reconciliation extension for 2023–25 increased outlays by tens of billions, and analysts continue to model large fiscal impacts for further extensions [2] [1].
6. Competing concerns: enrollment gains vs. improper payments and behavior
Proponents emphasize equity and coverage gains from the enhanced credits; critics argue the policies can create improper subsidies, encourage automatic re‑enrollment of people not using coverage, and blunt incentives — claims that some advocacy groups and think tanks make while proposing stricter verification or structural reforms [11] [12]. Available sources document both the enrollment uptick and critiques about waste, fraud, and program design — they do not definitively settle the magnitude of improper payments [1] [11].
7. What to watch next: congressional action, rate filings, and administrative rules
Key signals include whether Congress passes an extension (bills have been proposed but face uncertain prospects), insurer rate-setting for 2026 that may already assume different policy paths, and administrative rulemaking on enrollment and verification (some Biden administration rules also sought to streamline Medicaid/CHIP enrollment and renewal) [13] [14] [10]. If lawmakers fail to act, market guidance warns consumers to expect substantially higher net premiums and renewed eligibility cliffs [3] [4].
