2025 Window & Door Tax Credit
Access to federal tax incentives designed to reduce the cost of energy-efficient home improvements, including the installation of qualifying windows and exterior doors, is set to expire at the end of 2025. These incentives are part of the Energy Efficient Home Improvement Credit, which is available for improvements completed through December 31, 2025.
Overview of Tax Credits for Windows and Doors
Eligible taxpayers may claim a federal income tax credit equal to 30% of the cost of qualifying energy-efficient exterior windows and doors installed during the 2025 tax year, subject to item-specific and annual limits.
Window and Skylight Credit: Homeowners may receive a credit of up to 30% of the cost of qualifying windows and skylights, with a maximum credit of $600 per year for these items combined.
Exterior Door Credit: The tax credit for energy-efficient exterior doors is also 30 percent of cost, with a cap of $250 per door and a $500 total limit in a single tax year.
Credit Limits and Aggregation
These window and door credits are subject to the broader annual $1,200 limit applicable to qualified energy efficiency improvements under the Energy Efficient Home Improvement Credit. In addition to exterior doors, windows, and skylights, other qualifying improvements such as insulation or air sealing may contribute toward reaching the annual cap.
Eligibility and Requirements
To qualify, products must meet certain energy efficiency standards, typically demonstrated through ENERGY STAR or similar designations. Documentation of the manufacturer, model, and energy performance certification should be retained for tax filing. IRS Taxpayers claim the credit by completing IRS Form 5695 when filing their federal tax return for the year the improvements are placed in service.
Important Deadline
The Energy Efficient Home Improvement Credit, including the portion applicable to windows and doors, expires on December 31, 2025. Improvements must be installed and placed in service on or before this date to be eligible for the credit in the 2025 tax year.
