US Income Tax
From Wikibooks, the open-content textbooks collection
- AMENDMENT XVI. The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several states, and without regard to any census or enumeration.
This Wikibook covers federal income tax in the United States. It approaches the tax system from a legal perspective, not an accounting perspective. Rather than show how to calculate tax liability, it shows which factors lead to tax liability, and how different types of transactions are treated by the Internal Revenue Code.
