Best Answer: (I'll put this edit at the top instead of the bottom. I just realized this was a Canadian question, and I've given you US tax guidelines. I'll leave it in case it's relavent to yours as well.)
I assume you're talking about a corporation. As far as I know, no other form of business (except a estates and trusts) have their own tax tables. The following forms of businesses are NOT taxed:
(These forms of businesses act as "tax conduits" to the individual taxpayer, meaning that they file informational forms only, and their incomes are divided among partners or members and taxed only on the 1040 forms. There is an option for some of these company's to "check the box" to be
treated and taxed as a corp, though.)
Here are the corporate tax brackets:
18,333,333 and up: 35%
The 38% and 39% are called "hump" rates. Their purpose is to bring to a round percentage all of the lower brackets. For example, as soon as you've earned the last dollar in the 39% bracket, you'll find that you're going to pay 34% on all of it regardless of the lower brackets. The 38% bracket works the same way.
This gives corporations a shortcut. Any company making over 18,333,333 in income can just multiply all of it by 35% and ignore all other brackets.
