Glossary of Terms
U-Factor: The amount of heat flowing through a product. The lower the number, the more energy efficient the product is.
Solar Heat Gain Coefficient (SHGC): The ability to block heat generated by sunlight. The greater the blockage, the lower the SHGC.
National Fenestration Rating Council (NFRC): This organization conducts tests for energy efficiency based on the entire product, not just the glass.
ENERGY STAR: A government-backed program helping businesses and individuals protect the environment through superior energy efficiency.
Products That Qualify
To qualify for the tax credit, windows and exterior doors must be:
- ENERGY STAR qualified in the region where they will be installed. Click to see ENERGY STAR zones and requirements.
- Used to improve an existing home. This tax credit does not apply to new homes.
- Placed in service between December 31, 2005 and December 31, 2016. "Placed in service" is defined as when the property is ready and available for use.
- Installed in the taxpayer's primary residence.
How to Receive Your Tax Credit
Step 1: Consult your tax advisor. The tax credit is subject to a "Lifetime Limitation" of $500 ($200 for windows/skylights) in aggregate credits that a homeowner can claim from January 1, 2006 to December 31, 2016. So if you have already claimed more than $200 in window tax credits since 2006, you should not apply for the credit under this extension.
Step 2: Purchase qualifying windows and/or exterior doors. Look for the NFRC label on your product and make sure the U-Factor and SHGC ratings comply with the ENERGY STAR requirements for your region.
Step 3: Keep the receipts showing the purchase price of the qualifying products – excluding installation charges – and save the NFRC label from each window or door. Keep these with your tax materials in case of an audit.
Step 4: Download your Manufacturer's Certificate Statement and keep it with your tax records.
Step 5: Submit the credit with your taxes for the year the windows and/or doors were installed.
