What are the tax benefits of a stock day trader?

Answer 1

As above, day trading usually results in short-term capital gains/losses. So, if you're losing money with your trades, then you can offset some of your ordinary income. But, that's not exactly the best way to get a tax benefit.

Answer 2

There are no tax benefits to day trading, since you will not have long term capital gains. You will only realize short term gains, and those are taxed at your regular income tax bracket.
