In my line of work, specificity is important. For instance, the Form 10-K doesn't give you taxable income. Period. So, you can't "simply not exclude those items from a corporation's tax liabilities," especially since
tax liability actually refers to the taxes owed and not the income (or "profits") subject to taxation. Back when I was in corporate accounting, if the boss had asked me to book the tax liability and I booked the taxable income amount, I doubt my next review would have gone well.
Here's another place where specificity is important: I did not--I repeat, DID NOT--say that fines weren't tax-deductible as a group. I said that fines paid to the US government for a legal violation weren't deductible. And, they aren't. The link you gave specifically stated as such: "
Although the tax law forbids deductions for criminal fines and penalties owed to the government, other kinds of payments to compensate victims or correct damages are eligible for a tax deduction." So, your article actually proved my example (although looking up 162(f) of the IRC would have accomplished the same.)
And I also don't know why you keep bringing up statutory versus effective rates. I'm well aware of the difference. I even posted on it . . . in
2008.
