We want to be sure you don't pay a dime more in taxes on your investment profits than you have to. And, if you suffered a loss in the stock market—or on a real estate or other investment—in 2006, we want to make sure Uncle Sam picks up as much of that loss as possible. The rules are complicated and, just as if you were hiring a professional tax preparer, the more you know, the more TaxCut can help you.
