I declared myself a trader for tax year 2000, and I have a tax liability for the 4th quarter. I have never paid estimated taxes before. I'm not looking for tax advice here, but I would appreciate finding out how some of you pay your estimated taxes if you're declared a trader. Do traders pay a flat 28% capital gains rate? Or is it graduated, starting at 15% and going to 39% like business owners or regular paid workers? Do you deduct all your expenses from your profits? Do you pay estimated taxes to your state, or just the IRS? Do you depreciate your computer and computer equipment? I'm trying to call the IRS, but they won't even get back to me for 3 business days. I plan to check out Green & Co.
