avalancheone, do you mean& convert instead of recharacterize?
If you converted your traditional IRA to your Roth IRA, you must include in your income any taxable amount of the conversion, whether or not you had losses on the investments.
See Recognizing Losses on Investments at
http://www.irs.gov/publications/p590/index.html (Under Roth IRA) for information of claiming losses on Roth IRA investments
By the way, if you did convert your traditional IRA to your Roth IRA in 2004, you may reverse the conversion VIA recharacterization by October 15,2005, which would make the conversion null and void and therefore nontaxable.
