Tips on Locating Tax Cases That Relate to a Specific Code Section, Topic, CFR Part, or IRS Document

Looseleafs such as the Standard Federal Tax Reporter and the United States Tax Reporter contain case annotations for code sections.
Annotated codes such as the U.S.C.A. or U.S.C.S. have case annotations beneath the text of the code section.
KeyCite on Westlaw and Shepard's on Lexis provide case citations for cases that cite a code section. Click here for information on how to use KeyCite and Shepard's with code citations.
Shepard’s Federal Tax Citator (KF 6280.5.S46) lists cases that discuss a particular code section. Like other works in the Shepard’s series, it provides citations and treatment codes but no summaries of cases.
Search in an online source, such as a combined tax database on Westlaw (FTX-CSRELS or FTX-CS) or Lexis (FEDTAX;CASREL or FEDTAX;CASES), for tax cases by using the code section as the search term. Remember to limit the search by date and jurisdiction as dictated by the parameters of your assignment.

Use a combined tax database on Westlaw (FTX-CSRELS or FTX-CS), Lexis (FEDTAX;CASREL or FEDTAX;CASES), CCH Tax Research NetWork (U.S. Tax Cases) or RIA Checkpoint (Federal Tax Cases) and search using keywords.
