It was probably asked a million times but don't see exact answer to this question: -Assume I made $10,000 from trading in 2007 (short-term trades) -Assume I made $20,000 from my day-job, I do elect MTM due to my day job. How will I a be taxed on $10,000 day-trading income? Is it just added to my day-job income of $20,000 making my annual taxable income $30,000 or....$10K taxed seperately at different rate and term? Thanks.
