Winter is just about over, but it has probably served as a reminder that you need to replace those drafty windows for newer, more energy-efficient ones.

Not only will your home feel warmer, but you'll also save money, and there may never be a better time to make the investment.

If you bought new energy efficient windows in 2009, then you likely can claim a big tax credit when you file your taxes this year. You have the rest of this year to replace those windows for a tax credit next year.

It's pretty easy to figure out if those older windows need replacing.

“If you hold a candle up to the window for example, and the flame flickers, then you know you have a seal issue that you should probably consider replacing your windows. Also, the frames or the actual wooden part of the window can rot as well. An easy way to test that is to take a screwdriver and attempt to push on the wood part of the window. If it gives, it's a sign that the window may be rotting,” says Angie Hicks, consumer expert.

Replacement windows and doors aren't cheap, but Uncle Sam is making it very tempting not to make the investment.

“Currently there is a tax credit available to consumers for up to 30 percent of the cost of replacement windows or doors, up to $1,500. So now is a great time to think about replacing your windows if you've been putting it off,” says Angie.

This isn't a rebate. You would get the credit when you file your 2010 taxes, next year.

There’s another thing you need to consider.

“Not all windows and doors will qualify for the tax credit being offered, so consumers need to know what they are getting and understand the credit before they sign on the dotted line. And also keep the label from the windows you do buy so that you have that to give to your accountant when it comes to tax time,” says Angie.

It’s important to point out that the tax credit only applies to the windows and doors themselves, not labor.

So if replacement windows cost $5,000, your final cost will be $3500 with the 30-percent tax credit.

To take advantage, you must have the windows installed by the end December 31st, 2010.

There is a state tax deduction, which H&R Block says can be up to $1000. It’s not as helpful as a credit but the deduction will lower your overall tax bill, thus saving you more money.

In Michigan, joint filers can get a tax credit of up to $150.
