Investing in stocks with gross income (not yet taxed) cash from contract work?
You should get a 1099-MISC for the $5000 you got.  And your broker should send you a 1099-B for the $5500 sale of Google stock. These are two totally separate things as far as the US IRS is concerned. 1) You made $5000 in wages. You will pay income tax on this as well as FICA and other state and local taxes. 2) You will report that you paid $5000 for stock, and sold it for $5500 without holding it for one year. Since this was short term, you will pay tax on the $500 in income you made. These numbers will go on different parts of your tax form.  Essentially in your case, you'll have to pay regular income tax rates on the whole $5500, but that's only because short term capital gains are treated as income.  There's always the possibility that could change (unlikely).  It also helps to think of them separately because if you held the stock for a year, you would pay different tax on that $500.  Regardless, you report them in different ways on your taxes.
