Investing in stocks with gross income (not yet taxed) cash from contract work?
In most jurisdictions, you want to split the transactions. Why? Because you want to report capital gains on your investment income, and this will almost always be taxed at a lower rate than employment income. See Wikipedia's article for more information about capital gains. In Canada, you pay tax on 50% of your realized capital gains. There are also ways to shelter your gains from tax; in Canada, TFSA, in the US, I believe these are 'roth' accounts. I actually think you have to split the transactions, at least in Canada and the U.S., though I'm not absolutely sure. Regardless, you want to do so if you plan on making money with your investments. If you plan on making a loss, please contact me as I'm happy to accept the money you are planning on throwing away.
