Replacement Windows in Indiana

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

Indiana launched the Indiana Energy Saver Program (its IRA HOMES/HEAR implementation) in May 2025 through the Indiana Office of Energy Development, making it one of the earlier states to go live; windows may factor into whole-home HOMES projects via modeled savings, and funding is first-come, first-served — confirm availability at IndianaEnergySaver.com.

• Indiana Energy Saver Program (OED). The state's IRA-funded rebate program covers whole-home efficiency retrofits (HOMES) and electrification appliances (HEAR); windows are not a headline measure but envelope improvements can count within a modeled whole-home project.

• AES Indiana efficiency and weatherization programs. AES Indiana offers home improvement rebates and free weatherization for income-qualified households; window replacement is generally not a standalone rebate, but envelope work can be part of assessment-driven upgrades.

• CenterPoint Energy Indiana efficiency programs. CenterPoint's Indiana programs include no-cost home energy assessments, a Neighborhood Weatherization Program for eligible households, and an online efficiency store with weatherization kits — window insulation kits rather than full replacement rebates.

Energy code

Indiana's statewide residential energy provisions are based on the 2018 IECC with significant state amendments (in effect since late 2019), so permitted replacement windows should meet the amended IECC fenestration requirements for the state's cold-winter climate zones.
