Frequently Asked Questions:

Q: What is a tax credit?

A: Unlike a deduction, which reduces the amount of income subject to tax, a tax credit directly reduces the tax itself, or increases the amount of your federal tax refund.

Q: When is the deadline?

A: The tax credit applies to improvements made from January 1, 2009 through December 31, 2010. April 15, 2010 is the deadline to claim a credit for window, door, and skylight purchases on 2009 taxes. April 15, 2011 is the deadline for claiming a credit for window, door, and skylight purchases on 2010 taxes.

Q: How much money will I receive for installing windows, doors, and/or skylights?

A: By installing eligible windows and skylights, you may receive a tax credit of 30 percent of the cost. Exterior doors qualify for a tax credit of 30 percent of the cost up to $1500. Installation costs are not included. The maximum amount of homeowner credit for all improvements combined (including roofing, insulation, HVAC, and water heaters) is $1500 during the two-year period (2009 and 2010) of the tax credit.

Q: What windows, doors, and skylights are eligible for the federal tax credit?

A: All ENERGY STAR qualified windows and skylights that are installed in the taxpayer’s primary residence and are qualified in the appropriate ENERGY STAR climate zone are eligible to receive a tax credit. Most ENERGY STAR qualified exterior doors installed in the taxpayer’s primary residence and qualified in the appropriate climate zone are also eligible to receive a tax credit, with the exception of exterior doors installed in certain parts of California.

Storm windows and storm doors are also eligible for tax credits. for more information on tax credits for storm windows and storm doors.

  1. Purchase receipts
  2. All ENERGY STAR/NFRC labels from the installed doors (if available)
  3. Manufacturer’s Certification Statement or equivalent, which proves the product is eligible
