you dont pay taxes on fees. They add to your basis and reduce your net sale proceeds, so your overall capital gain is lower.
Give us some more information.
You are only taxed on your actual GAIN...
A $50 "profit" on $1,200 (including the $7 buying and $7 selling fee) means you are really only making $36 per trade, or less than 0.3%
I'm a novice US investor. I have two investments of about $1,200 each, usually in big oil or leveraged ETFs. I decided to sell after I reach $50 in profit for each investment including the $7 buying and $7 selling fee, which isn't that hard in this market. And then rebuying similar or same stock or ETF. So am I getting soaked on the taxes for the fees?
