Tax Law Research : Federal and Ohio: Federal Legislative History


Legislative history is useful for determining the intent behind a law, whether you're trying to determine why the law was changed or what Congress meant by a specific phrase. Legislative history is typically found in documents created during the legislative process, including reports, hearings, records of debates, and different versions of the bill. 

Where does Legislative History fit in the Hierarchy?

Legislative history is a primary source that provides guidance, but it should not be cited as legal authority. Courts can only look to the legislative history of a statute to “explain the meaning and purpose of a provision whose text is genuinely ambiguous.” Sherfel v. Newson, 768 F.3d 561, 569 (6th Cir. 2014).  The documents of legislative history for tax law research purposes are listed below:

1. Congressional Committee Reports / Conference Reports
2. Text of earlier or alternative versions of a bill
3. Floor Debates (Congressional Record)
4. Statements or testimony at Committee Hearings
5. Committee Prints
6. Presidential Signing Statements
