Tax Research


This research guide is designed to assist students, scholars, and practitioners in researching United States tax law.  Federal tax law is composed of statutes, treaties, regulations, rulings, and judicial decisions from the government’s executive, legislative, and judicial branches.  This guide also offers sources for current awareness in tax law, including updates on case law, legislation, and legal news.

Research guides are very helpful when researching tax law, as they provide both explanation of the subject matter and direction for locating publications where tax documentation can be found.
