3.  $500 total maximum tax credit for any and all improvements, including other eligible items as listed in the IRS Notice (Section 25C of the Internal Revenue Code)

4.  $200 total maximum tax credit for qualifying windows and skylights

5.  $500 total maximum tax credit for all qualifying improvements, including windows or skylights

Andersen verifies only that its products with an ENERGY STAR label manufactured in 2015 will meet the ENERGY STAR version 5.0 performance criteria and products and products with an ENERGY STAR label manufactured in 2016 meet the ENERGY STAR version 6.0 performance criteria for the particular climate zones indicated on the label. Andersen bears no responsibility for determining whether a particular purchase or application qualifies for the tax credit. Further, Andersen does not intend to and is not providing legal or tax advice and recommendations that purchasers consult their own tax advisor or the IRS to determine whether the products they purchase for a particular application qualify for the tax credit.

** Andersen windows and doors with High-Performance Low-E4®, High-Performance Low-E4 Sun, High-Performance Low-E4 SmartSun™, High-Performance Low-E or High-Performance Low-E Sun glass qualify in many U.S. ENERGY STAR climate zones when used for remodeling, replacement or home improvement.  As the ENERGY STAR criteria differs by climate zone, please review the ENERGY STAR requirements in the climate zone where the product will be installed and refer to the Andersen NFRC Ratings/ ENERGY STAR Qualifications sheet to select the product.  Please consult your tax planner and review all IRS guidelines.
