Federal Taxation

Internal Revenue Code

Title 26 of the U.S. Code is known as the Internal Revenue Code (IRC). This is where most laws that deal with federal taxation are codified. Some tax-related laws are published in other titles of the U.S. Code. The U.S. Code is available in numerous places, including in print, on subscription databases like Lexis and Westlaw, and freely available on the internet. See the United States Code research guide for how to access the U.S. Code.

New tax legislation is also published in the Internal Revenue Bulletin. For where to find the Internal Revenue Bulletin, see the Internal Revenue Bulletin page of this guide.

Commercial publishers reprint the Internal Revenue Code in other sources. A selection of these sources is listed below.

For historical versions of the Internal Revenue Code as available in the U.S. Code, see the Historical US Code page of the United States Code guide.
