One thing to keep in mind is the non-monetary side of taxes: they are used to influence behavior. Offering employee benefits (healthcare, retirement, etc.) is incentivized by US tax code thus influencing more companies to do so.

I'm not saying that corporate behavior becomes uninfluencable when profit taxation is removed, but rather that it will require a different incentive mechanism. That is assuming that we still want to influence corporate behavior through government without legislating it.
