Here is a question in my review course:
The Tinkers, Evers, and Chance Corporations have taxable income, all resulting from regular operations, of $100,000, $300,000, and $450,000, respectively. None is a member of a controlled group. The tax liabilities before credits in the current year are:
No tax tables are given. The correct answer is Tinkers $22,250; Evers $100,250, and Chance $153,000 and it is computed by multiplying the first $50k by 15%, next $25k by 25%, income above $75k by 34%, and some other adjustment I don't really understand.
My question is, simply, am I really supposed to have these tax rates memorized?
