Taxes are never taken out. It’s like if you charged 500$ to fix toilets, all the people whos toilets you fixed would just give you 500$, and it’s up to you keep track and report earnings + pay taxes.
I don’t know about the different bank accounts thing. But, if someone (Epic) is sending you a 1099, they are also sending that info to the IRS. - So maybe the IRS expects to see taxes paid for whoever’s name is on the 1099.
