Is the IRS going to kill me for this?

[Account Closed]

I had to make this topic over, I hated the way that typo looked on the other topic but here's the situation.
I'm a full time wholesaler and am looking to make a significant amount of money wholesaling this year (goal is 300k). Now I'm also going to be rehabbing houses this year but I'm trying to find out how much of my profits I should put away for taxes. What do you guys suggest? 1/3 or 1/2? If you tell me a half I'm going to throw up lol. But seriously I'm just trying to make sure if I put a percentage in an account for taxes be good at the end of the year. Thanks in advance.
