Why is $3000 in capital losses not being deducted from my federal tax of ~$1000?

[Jack2572]

I owe roughly ~$1,000 in federal income tax. When I enter my capital losses of $3,000+ in the TurboTax Free File Program, only a very small percentage is deducted from the total tax owed. Can anyone explain this? I was under the impression that I should not have to pay any taxes if my short term capital losses were greater than my federal income tax due. Thanks!

Capital losses reduce your taxable income, thereby reducing your tax.  Capital losses are not tax credits and do not lower your taxes dollar for dollar.  A $3,000 capital loss would translate to a small amount of tax.
