The act of reducing the manpower of the IRS needed to enforce the laws may have a greater effect than all the tax cuts combined. If a business is fairly certain an audit isn't coming, their effective tax rate is whatever they want it to be.
Exactly, considering the penalties are just paying whatever is owed anyway, perhaps plus a few minor interest penalties. They make more the fines and interest combined by a long shot just by deploying the saved funds elsewhere.
This is not at all true.
