Where can I find official 2026 poverty guidelines and calculator for ACA enrollment?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
For official 2026 federal poverty guidelines, the U.S. Department of Health and Human Services (HHS/ASPE) publishes the poverty guidelines that federal programs use; the ASPE poverty-guidelines page is the authoritative source cited in reporting [1]. For ACA enrollment calculators and subsidy estimates, established non-governmental tools updated for 2026 — KFF’s Marketplace/Subsidy calculators and healthinsurance.org’s 2026 subsidy calculator — incorporate IRS/IRS‑released 2026 affordability caps and the relevant FPL figures used to compute premium tax credits [2] [3].
1. Where to get the official poverty guidelines — go to ASPE
The official HHS poverty guidelines that underlie ACA eligibility rules are maintained by the Assistant Secretary for Planning and Evaluation (ASPE); ASPE’s poverty-guidelines page is the explicit source agencies and programs cite for the formal numbers states and federal programs use [1]. Many secondary charts and calculators reference ASPE as their source (for example, the health‑reform reference chart that points to aspe.hhs.gov for mainland, Alaska and Hawaii numbers) [4].
2. Which FPL year is used to determine 2026 Marketplace subsidies
Reporting and calculators for 2026 coverage generally base subsidy eligibility on the 2025 poverty guidelines (the guideline year used to determine coverage-year 2026 subsidies), and many subsidy tools explicitly say they use the 2025 FPL to calculate 2026 marketplace assistance [4] [5] [6]. That distinction matters: the numerical FPL table you use depends on whether you are calculating for calendar-year 2026 taxes or coverage-year 2026 subsidies — available sources show subsidy tools used 2025 FPL for 2026 coverage [4] [6].
3. Official IRS affordability threshold for employers (FPL safe harbor)
For employer ACA affordability safe‑harbor calculations for 2026, the IRS set the affordability percentage at 9.96% and agencies and payroll vendors translate that into a monthly FPL‑based threshold — widely reported as roughly $129.89–$129.90 per month for single‑person coverage using the mainland FPL figure cited for 2025/2026 guidance [7] [8] [9]. Employer guidance pieces explicitly quote the 9.96% threshold and the equivalent monthly cap when using the Federal Poverty Line safe harbor [7] [8].
4. Where to find trustworthy ACA subsidy and affordability calculators
Several organizations with reputations in health policy and consumer tools maintain calculators updated for 2026: KFF’s Marketplace/Subsidy Calculator has been updated to reflect 2026 premiums and IRS contribution caps and notes it uses 2026 premiums and updated FPLs when updated [2]; healthinsurance.org offers a 2026 subsidy calculator and explains which FPL year and enrollment windows apply [3]. Independent sites such as ObamacareFacts, HealthCareInsider and MyHealthInsurance also publish 2026‑specific calculators and charts, and they state which FPL year and subsidy rules they apply [6] [10] [5] [11].
5. Practical steps — which pages to bookmark and why
Bookmark ASPE’s poverty-guidelines page for the canonical numbers [1]. For consumer subsidy estimates, use KFF’s Marketplace calculator and healthinsurance.org’s subsidy calculator; both are explicitly updated for 2026 inputs and explain assumptions around the IRS caps and the FPL year used [2] [3]. If you are an employer checking affordability safe‑harbors, refer to IRS guidance summaries cited by payroll/benefits vendors (reports quoting the 9.96% rule and the $129.89/month FPL safe‑harbor figure) [7] [8] [9].
6. Conflicting details and limitations in current reporting
Sources agree generally on the major mechanics — ASPE supplies FPLs; IRS issued 2026 affordability at 9.96% and vendors converted that to a monthly FPL safe‑harbor dollar figure — but there is variation in how secondary sites label which year’s FPL applies for specific purposes (coverage-year vs. tax-year distinctions) and in rounding of the monthly FPL dollar figure ($129.89 vs. $129.90) [4] [7] [8] [9]. Available sources do not mention a single consolidated “official ACA calculator” run by HHS or IRS for consumers; instead, federal pages (HealthCare.gov) provide enrollment tools and state marketplaces run calculators while independent organizations assemble user‑friendly estimators [12] [3].
7. Bottom line and recommended next action
If you need the legally authoritative FPL numbers, use ASPE’s poverty guidelines [1]. For practical subsidy estimates for 2026 enrollment, use KFF’s Marketplace/Subsidy calculator and healthinsurance.org’s 2026 subsidy calculator which explicitly claim updates to reflect IRS 2026 caps and the relevant FPL inputs [2] [3]. If you represent an employer checking affordability safe‑harbors, rely on IRS guidance as summarized by payroll-benefits vendors and confirm whether your plan year uses the 2025 or 2026 FPL for the safe‑harbor calculation [7] [8].
