Replacement Windows in Washington

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.

Washington runs IRA Home Energy Rebate programs; whole-home efficiency retrofits can include windows. Confirm current status and funding availability before promising rebate money.

• Seattle City Light / Puget Sound Energy efficiency programs. Washington's utilities — including Seattle City Light and Puget Sound Energy (PSE) — fund home efficiency and weatherization; window replacement generally qualifies as part of whole-home efficiency work.

Energy code

Washington enforces the Washington State Energy Code, among the strictest in the nation; Seattle permits through the Department of Construction & Inspections (SDCI), and the code sets a high bar for replacement windows.
