What are the 2025 income limits for premium tax credits by household size and state?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The premium tax credit (PTC) for coverage year 2025 is determined by federal poverty guidelines applied to household size, with eligibility generally beginning at 100 percent of the federal poverty level (FPL) and—in most descriptions prior to 2026—capped by policy changes at 400 percent of FPL; however, congressional actions extending COVID-era enhancements mean there is effectively no upper income cap for the enhanced rules through the end of the 2025 coverage year (Health Reform Beyond the Basics; IRS) [1] [2]. To convert those percentage rules into dollar thresholds for each household size in each state, use the 2025 federal poverty guidelines for the 48 contiguous states/DC (with higher guidelines for Hawaii and Alaska) as the baseline and multiply by the relevant percentages or, under the 2025 enhancements, apply the “no maximum” rule while remembering special programs and state differences [3] [4].
1. How eligibility is framed: percent of the federal poverty level, not a fixed state table
Eligibility for the PTC is framed in relation to the federal poverty level—eligibility generally requires household income at or above 100% of the FPL and, under traditional ACA rules, at or below 400% of the FPL, but the American Rescue Plan Act and subsequent legislation extended enhanced rules through 2025 that remove the 400% ceiling for that coverage year so that people above 400% can qualify if their benchmark premium would cost more than a capped share of income [5] [1] [6].
2. Converting percentages to dollars: use the 2025 poverty guidelines by household size (and adjust by state)
To produce dollar limits by household size, multiply the 2025 poverty guideline for the relevant household size by the percentage threshold (100%–400%) or treat the upper bound as open under the temporary 2025 expansion; the government’s poverty guidance used for 2025 plan-year determinations is the reference point and includes specific higher figures for Hawaii and Alaska and add-on amounts for households larger than eight [4] [3]. For practical examples drawn from the reporting: the 2025 guideline cited for a single adult was about $15,060 and for a family of four ranges roughly around $31,200–$32,150 depending on the source and whether one uses ASPE or CMS parameters, and those base numbers are what gets multiplied to find 100% or 400% thresholds [7] [4].
3. State-level wrinkles: BHPs, state-based marketplaces, and geographic price differences
States affect how the dollar value of the PTC translates into premiums because the credit equals the difference between a region’s benchmark (second-lowest-cost silver plan) premium and a capped percent of household income; two states (Minnesota and Oregon) operate Basic Health Plans with different eligibility cutoffs (e.g., up to 250% FPL) and state-based marketplaces can set different enrollment windows that affect plan-year rules, so the same household-size-to-FPL calculation can produce different out-of-pocket premium obligations depending on the state and county premium levels [5] [1].
4. What changes after 2025 and why that matters to limits
The enhanced, no-upper-cap approach to the PTC is explicitly time-limited through the end of the 2025 coverage year; analysts and budget offices project that, unless Congress acts, eligibility will revert to the 100%–400% FPL framework and subsidy generosity will shrink beginning in 2026, which means the practical “income limits” people face will tighten back to below 400% for most filers after 2025 (Congressional Budget Office; Bipartisan Policy Center) [5] [8]. Reporting also notes regulatory and legislative changes in 2025 that tightened verification and reenrollment rules, which could further narrow or complicate state-by-state access even where the FPL math would seem to allow credits [9] [10].
Bottom line
There is no single printed table of “2025 income limits by household size and state” in the provided reporting; instead, determine 2025 thresholds by applying the 2025 federal poverty guidelines for the household size (with Hawaii/Alaska adjustments) to the percentage range that governs eligibility—bearing in mind that, for the 2025 coverage year, enhanced rules removed the 400% ceiling so there is effectively no maximum income limit to the enhanced PTC but state program rules and geographic premium differences determine the actual dollar subsidy and who benefits [3] [1] [5].
