Its still just two categories revenue/costs. Not all costs are legitimate business expenses and tax deductible.

Certainly, penalties that follow as a result of violations of law should not be tax deductible business expenses.

Every single cost is. The only thing corps are taxed on is profit if you pay a fine you made less profit there isn't some hidden bullshit.

>Every single cost is.

No.

Taxes are expenses, taxes are not tax deductible.

The most common fines and penalties (late fees on federal and state tax returns, are not tax deductible (nor are parking tickets or safety violations).

Insurance is an expense, some insurances premiums are and some are not tax deductible.

Capital Expenses and Equipment, depends, but usually not deductible as a expense but as depreciation over time.

Commuting Costs, generally non-allowable deductions.

Home Office, its tricky and full of bullshit. Same with personal expenses (car/phone)

Political Contributions, tricky and full of bullshit, generally not tax deductible.

Corporate gifts? your deduction is capped at $25.

The Tax Code doesn't have bright-line rules like "every cost" is tax deductible.

That's definitely not true. I'm not an expert in US tax law, but there are a number of important differences between accounting and tax income/expenses:

* Fines, as other people have stated, are usually not deductible. They aren't in Canada, for sure, and they are added back to income (i.e. you're taxed on that amount).

* There is usually a big difference between how leases are treated for accounting purposes and for tax purposes

* Accounting requires that things like accounts receivable to be measured at the expected value. Accounting generally requires an allowance to be booked as an expense for doubtful accounts, even if you don't know which accounts are doubtful. This is usually done on a basis like, historically 2% of accounts are doubtful, so we'll book that expense. For accounting, that's fine, but for tax purposes only actual bad debts are deductible.

* In Canada, capital gains are taxed at 50%, while for accounting purposes 100% of the gain is included in income.

* Capital asset purchases are not deductible, but are depreciated instead over time

* There's limits on things like meals and entertainment. In Canada, only 50% of them are deductible as it is assumed there is always a personal portion to a meal.

So it's not like everything is always deductible, there are many things that income is adjusted for for tax purposes.

Evident counter example: penalties to the IRS. Very analogous to the costs here discussed, no need to look for "bullshit".
