Replacement Windows in Wisconsin

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.

Wisconsin has been rolling out IRA Home Energy Rebate programs; whole-home efficiency retrofits can include windows within a modeled-savings project. Confirm current availability before promising rebate dollars.

• Focus on Energy (statewide). Focus on Energy is Wisconsin's statewide utility efficiency program; it incentivizes audits and weatherization, with windows typically part of a broader whole-home efficiency package. (Focus on Energy program pages)

Energy code

Wisconsin enforces the statewide Uniform Dwelling Code (UDC); Milwaukee permits through the Department of Neighborhood Services. Zone 6 winters make low U-factor windows effectively essential for permitted replacements.
