I would like to know if the money I make from trading/interest on stocks and bonds is subject to double taxation? I have found that US bonds are not subject to state and local taxes, but they are taxed by the government. However, it did not say if they are single or double taxed.

Anyways, this seems like a safe way to get more interest than keeping my money in the bank either way. Stocks are a bit more risky, but a mutual fund can usaully work out well. I plan to divide up my investing to be safe.

Last, are there are tricks to making bonds and stocks subject to only single taxation? For example, if I bought them through a sole propietorship or an LLC instead of persoanlly?

Hopefully there is a stock trader or bond buyer ot clue me in :-P Thanks for the help.
