Here is a good explanation why corporations are taxable:

Corporations are participants of the economy and their profits depend on tax-financed public goods: healthy and educated workforces; good infrastructure; publicly enforced respect for contracts and property rights, and so on. When corporations avoid or evade tax, legally or illegally, they free ride on the backs of the rest of us. Stop taxing them, and you savagely undermine political community.
