In some ways state and local taxation closely resembles the federal taxation scheme. As with the federal system, the state legislature is charged with passing its taxing statutes, similar to the Internal Revenue Code. Analogous to the Internal Revenue Service on the federal level, each state has a corresponding regulatory tax agency that passes state administrative regulations and rulings. Similarly, state courts generate judicial opinions, although most states do not have an official tax court.
State personal and corporate income tax issues can be researched largely in the same way federal tax research is conducted. Indeed, many states' personal income tax merely "piggybacks" on the federal income tax, and thus, a large component of the research will be in the federal sphere.
However, states engage in a wide variety of different taxes that are unrelated to income: e.g., property taxes, sales & use taxes, excise taxes, estate and inheritance taxes, and liquor taxes. Often, these different tax laws are scattered throughout the states' codes and are not codified together into a cohesive "tax code." Accordingly, using specialized state tax resources will help streamline the research process.
This research guide is designed to serve as a starting point for conducting research in state tax laws. It will include both print and electronic resources available in the Georgetown Law Library.
For more detailed information about conducting legal research in a particular state, please consult the Georgetown Law Library's state research guide for the state you are interested in.

State tax statutes are found with the state code compilation for its respective state. Because each state code compilation has a different name, the easiest way to determine the name of a state code compilation is to use Jurisdiction Table 1 in the Bluebook or consult the Georgetown Law Library's state research guide for the state you are interested in.
Not every state has a stand-alone "tax code." In many states, tax-related statutes are spread throughout their code. For these states, using one of the state tax-specific resources listed in the "loose leaf services " section of this guide may be more helpful than using the state's annotated code.
Both Westlaw and Lexis have compiled each state's tax statutes into narrow, specialized databases.
Like in the Federal tax system, each state has an administrative agency that enforces the tax law, drafts regulations, and issues administrative guidance. In most states, this agency is usually the Treasury or the Office of the Comptroller. In some states, the Attorney General's office also produces administrative guidance in the form of letter rulings.
Each state's regulatory compilation has a different name. The easiest way to determine the name of the compilation is to use Jurisdiction Table 1 in the Bluebook or consult the Georgetown Law Library's state research guide for the state you are interested in.
Both Westlaw and Lexis have compiled each state's tax regulations into narrow, specialized databases.
Most states do not have a specialized tax court like the United States Tax Court. However some states have special tax tribunals that hear tax disputes before they enter the court system. At the state level, there are no state tax case reporters such as American Federal Tax Reporter or United States Tax Cases. To locate state tax case law, state tax researchers must use the designated state digest and reporter system for their jurisdiction. Please consult the Georgetown Law Library's state research guide for the state you are interested in for additional information on conducting case research in that state.

When conducting tax research, it is often easier to work with specialized tax loose-leaf services and databases than with more general legal databases. This is particularly true when researching state tax issues because state tax statutes may be located in various places throughout a state's code and because there is no uniformity between the ways different states handle tax administration and regulation. In addition, these specialized tax resources provide invaluable editorial content, annotations, and explanations, which are not available in the more general databases.
Georgetown subscribes to the following specialized state tax loose-leaf services and databases.
The following journals do not specialize in state tax law, but nonetheless may be useful resources.
