I think it might be interested only US system vendors, but the info is something for considering.
I just came back from my accouter. It’s tax season you know 
Subscription fees:
C2 takes 30% cut. (It’s well deserved and no complaints from my side)
Uncle Sam takes ~40% (estimation so far) cut from rest of C2’s subscription income in my situation.

P.S. Just a fact that you might be interested.
On top of these, we have to waste a lot time and efforts to keep all the paper record complete and organized then pay our Accountant in order to pay Uncles Sam.
Anyone have good experiences of good software to keep tract of all the trading records?
in many cases your broker can provide you with an overview of all trades executed during the past year.
