This phrase can be broken up into two parts. "Tax That Ass" is to have sex with a female in a manner that depletes the energy of the female; in a sense, "taxing" her stamina. The second part, "Like Woah," emphasizes the taxing of the ass.
1) That bitch desires my penis, I'm about to tax that ass like woah!
