While that is true (depending on the jurisdiction), I find it weird that this is so readily acceptable when talking about a corporation when all of us are taxed on our income before it even reaches our bank account.
Besides, corporations generally have outside sources of funding other than income, while people generally don't. Thus corporations can run at a deficit, sometimes for a long time, while they figure out how to turn a profit. Do you think there's really a societal benefit to drive new businesses into bankruptcy before they get their footing by taxing them while they're losing money?
What do you think credit cards and mortgages are?
What do you think a tax deduction for mortgage interest is, if not a way to avoid taxing individuals on part of their revenue?
