Tax Law

Secondary Sources

A secondary source is one that explains, analyzes or interprets the primary sources, but is not a primary source itself. Although secondary sources are not authoritative, they are nevertheless an integral part of any tax research strategy.

Tax Services

Tax services were originally produced in looseleaf form (print), but are now available online. These services are arranged by Internal Revenue Code section or by topic. They contain explanations of Code and Regulations sections, as well as cross-references and annotations to relevant cases, IRS materials and other authorities. They also include explanations of the relevant topics written by experts.
