2026 Premium Tax Credit Tool: An Interactive

Tool for Congressional Users



Updated December 2, 2025

This Insight accompanies the 2026 Premium Tax Credit Tool, a Microsoft Excel file that congressional
users can download from CRS.gov. The tool was designed to assist Congress in evaluating policy
considerations in advance of the expiration of certain premium tax credit (PTC) provisions at the end of
2025. It can be used to demonstrate how potential changes to certain statutory parameters of the PTC
would affect credit amounts for households with varying income levels, family characteristics, and
geographic locations.


Background on the Premium Tax Credit

Certain households without access to subsidized health insurance coverage may be eligible for the PTC if
they enroll in coverage purchased in the health insurance exchanges. The PTC was established under the
Patient Protection and Affordable Care Act (ACA; P.L. 111-148, as amended) and amended under the
American Rescue Plan Act of 2021 (ARPA; P.L. 117-2) and the enacted budget reconciliation measure
(P.L. 117-169) commonly referred to as the Inflation Reduction Act. Several amendments are temporary.
The credit amount for a household generally is calculated as the difference between the Second-Lowest-
Cost Silver Plan (SLCSP) Premium and the Required Premium Contribution as per the following formula:
       Premium  Tax Credit Amount = SLCSP Premium  - Required Premium Contribution
SCLSP Premium  refers to the premium for the second-lowest-cost silver plan in the household's local
geographic area for its family status. Required Premium Contribution refers to the amount a premium
credit-eligible household may pay toward the plan premium.
The Required Premium Contribution is calculated by taking a percentage of the household's income. The
applicable percentage is specified in statute and varies according to household income relative to the
federal poverty level (FPL), using poverty guidelines updated by the Department of Health and Human
Services (HHS) for the previous year. Thus, for example, the 2025 HHS poverty guidelines will be used
to determine the 2026 PTC.
