Federal Income Tax Guide

This guide is an introduction to federal income tax resources available at Marquette University Eckstein Law Library.

Tax research follows the same process as other legal research.  Legal authority consists of primary and secondary sources.  Primary authority refers to statutes, treaties, regulations, rulings and judicial decisions.  Secondary authority, such as treatises, loose-leaf services, and periodicals, explain and analyze primary sources.

When researching tax issues, the appropriate Internal Revenue Code (IRC) section needs to be identified, followed by the regulations issued under that section.  Court cases and official Internal Revenue Service documents are then found for further support.
