What are the 2025 income eligibility limits for ACA premium tax credits?

Executive summary
For the 2025 coverage year, premium tax credit eligibility requires household income at or above 100% of the federal poverty level (FPL), and enhanced subsidies in 2021–2025 removed the traditional 400% FPL upper limit so some people above 400% can qualify if benchmark premiums exceed 8.5% of income [1] [2]. Those enhanced rules are temporary and set to expire at the end of 2025 unless Congress extends them; after that the normal 100%–400% FPL band generally returns [2] [3].
1. What the floor is: the 100% FPL minimum
To claim a premium tax credit for 2025 you must have projected household income at or above 100% of the federal poverty level for your family size [1]. That floor matters because individuals below roughly 100% FPL in states that expanded Medicaid typically qualify for Medicaid instead of marketplace credits [4]. The federal poverty figures used for eligibility are published annually by HHS [5] [4].
2. The missing cliff in 2021–2025: no fixed 400% cap
Policy changes since 2021 — the American Rescue Plan and its extension through the Inflation Reduction Act and subsequent guidance — eliminated the strict 400% FPL cutoff for the 2021–2025 coverage years. That means there is no automatic upper-income cap for subsidy eligibility in 2025; people whose benchmark Silver-plan premium would otherwise exceed 8.5% of their MAGI can receive credits even if their income exceeds 400% FPL [2] [6]. Multiple policy analyses and government guidance reiterate that enhanced credits expanded eligibility above 400% through the end of 2025 [7] [6].
3. How the credit amount is still tied to income percentages
Even with the expanded eligibility, the premium tax credit calculation caps how much an enrollee must contribute toward the benchmark plan as a share of income. For 2025, required contribution schedules concentrate relief at lower FPL percentages (for instance, zero required contribution up to about 150% FPL and rising to 8.5% at and above 400% under the enhanced rules) — KFF and CRS summaries document these applicable-percentage schedules used in 2025 [4] [8]. In short: eligibility expanded, but the subsidy size remains an income-indexed cap on your share of premiums [4].
4. The deadline risk: enhancements set to expire end of 2025
Available reporting is unanimous that the enhanced subsidy rules are temporary and scheduled to end after the 2025 coverage year unless Congress acts to extend them. Analysts and agencies warn that if enhancements lapse, the normal statutory structure — which generally limits eligibility to those between 100% and 400% of FPL — will largely return for 2026, shrinking both eligibility and subsidy size [3] [2] [9].
5. Practical numbers and poverty guidelines used in 2025
Marketplace tools and HHS guidance show the FPL amounts used for 2025 calculations (for example, HHS’s published poverty guidelines and interactive KFF tools that use $15,060 for a single adult and $31,200 for a family of four in 2025 marketplace calculations) — those base numbers are what determine whether your household falls above 100% FPL and where you sit on the sliding scale [5] [10].
6. Conflicting guidance and where confusion comes from
Federal law (ACA) originally set a 100%–400% FPL eligibility band; the temporary post‑2020 laws and subsequent agency guidance removed the 400% ceiling through 2025, producing mixed messaging: IRS instructions still describe the ACA baseline test, while policy briefs and marketplace help pages emphasize the 2021–2025 enhancements [11] [2] [6]. Reporters and calculators frequently note both sets of rules; the conflict is not an error in the sources but the result of overlapping statutes and time-limited policy changes [6] [3].
7. What this means for consumers shopping in 2025
If you apply for 2025 marketplace coverage, expect eligibility to be determined using 2025 benefit‑year rules: you must be at least 100% FPL, but you may still get a credit above 400% FPL if the benchmark premium exceeds 8.5% of your MAGI; subsidy amounts will be calculated using the 2025 applicable percentages [1] [2] [4]. Consumers should use official marketplace calculators or KFF’s subsidy tools that are updated for 2025 to estimate whether they qualify [10].
8. Limits of current reporting and next steps
Available sources document the 2025 rules and the scheduled expiration of enhancements at year-end 2025, but they do not say whether Congress will act after 2025 to continue the expanded eligibility — that outcome is not covered in the materials provided [3] [2]. If you need an exact dollar threshold for your household size, consult HHS poverty guidelines or marketplace calculators referenced above; for legal certainty about 2026 and beyond, watch congressional action and IRS/CMS guidance [5] [10] [3].
