Tax for Traders

http://fairmark.com/traders/

This is a tax guide for Traders, a tricky subject, and somewhat left open to interpretation.   If you treat your trading as a real trading business, you can deduct all losses (not just limited to $3000) but there are also large ramifications.    However, capturing losses should not be a prime driver, cause maybe that just means that something else is just not right about your "business".  

And make sure your paid tax professional agrees with any interpretations, as it could be disastrous to make an assumption and then have it not work out.
