What Are The Requirements for the 2009-2010 Energy Tax Credit For New Windows?

The number one question customers ask about the new energy  tax credit for replacement windows is: “Which windows qualify?” It’s a great question, because the government has tightened up the standards.

Back when the credit was first offered in 2006 and 2007, Energy Star certification was the only requirement. But window technology has improved in the few years Energy Star set their standards. The new tax credit raises the standards a full 25% above Energy Star. That means you can’t trust the Energy Star label on your window to get your $1,500.

By raising the standards, Congress and President Obama have actually done something smart. You’ve got a great incentive to replace your windows with new, energy-efficient ones that will start saving you money on energy bills. Plus, we can finally start reducing our energy consumption and become energy independent.

NFRC: The New Benchmark For Window Ratings

Energy Star plans to raise their requirements in 2010. For now, you can trust the National Fenestration Ratings Council (NFRC) to tell you which windows qualify. The NFRC is non-profit organization that scientifically tests each and every replacement window for energy performance.

If you’ve ever bought a window, you should have seen an NFRC label. That sticker tells you some very important information, including the U-Factor and the Solar Heat Gain Coefficient (SHGC) of the windows. The standards for the tax credit are based on those two ratings.

Just find the NFRC sticker on any replacement window to check the U-Factor and SHGC for yourself.

Just find the NFRC sticker on any replacement window to check the U-Factor and SHGC for yourself.

A low U-Factor will stop heat loss, which keeps your home warm and cozy, and your energy bills low, in the winter. A low SHGC helps block the sun’s heat from your home so you can use your AC more efficiently and stay cooler for less money. For both U-Factor and SHGC, low values are better. You want a number closer to 0.

To qualify for the energy tax credit, your new windows must have a U-Factor and a SHGC of .30 or less. .31 on one and .29 on the other won’t cut it. Both have to meet the standards. Examine that NFRC sticker carefully, or verify the ratings yourself over at

Let’s Start Saving Energy Now…Before It’s Too Late

The price of energy is only going up, and replacement windows aren’t getting any cheaper. The government is only offering this credit for two years. They want you to start saving energy NOW. The Department of Energy says that if every American home upgraded to the new standards, we would save the energy equivalent to what five coal power plants produce. That’s each year.

So let’s help out our country. You’ll also help yourself because you’ll stay more comfortable all year round and save money on your energy bills.

You can make the entire process easy by choosing Mr. Rogers Windows. You’ll find windows that qualify you for the tax credit in all your favorite styles.

Check back in a day or two. I’ll have some more information about the tax credit.

  1. Can we still get the tax write off if we accidentally threw away the energy star stickers from the new windows? Thanks for your help!

    • The Energy Star stickers are not as critical to your tax credit documentation as the Manufacturer’s Certification Statement. Every manufacturer is required to make this available. That certification document, plus your sales contract will verify the style number and type of window you purchased and installed. This should be adequate.

      As with most tax documentation, you do not need to send this to the IRS or provide it to your tax preparer. However, if audited, these documents will be required. Now, you know I am not a tax adviser, but this is my understanding. Hope it helps.
