Lesson 3: Tax Code Structure

Welcome to Lesson 3 of our Introduction to Federal Income Tax Law series on kindalawful.com. This lesson will provide an overview of the Tax Code Structure essential for understanding Federal Income Tax Law.

Understanding the Tax Code

The Internal Revenue Code (IRC) is the primary source of federal tax law in the United States. It is a comprehensive set of tax laws enacted by Congress, and it is codified in Title 26 of the United States Code.

💡 The Internal Revenue Code (IRC) is frequently updated, so always ensure you are referring to the latest version.

Hierarchy of Tax Law

Tax law in the United States consists of a hierarchy of sources:

Statutory Law (Internal Revenue Code)
Administrative Authority (Treasury Regulations, IRS Revenue Rulings)
Judicial Authority (Court Decisions)

⚠️ Understanding the hierarchy of tax law is critical for interpreting and applying tax regulations accurately.

Internal Revenue Code (IRC)

The IRC is divided into several subtitles, which are further divided into chapters, subchapters, parts, and sections. The most commonly referenced sections include:

Sections 1-1400: Income Taxes
Sections 2001-2801: Estate and Gift Taxes
Sections 3001-5000: Miscellaneous Excise Taxes

Treasury Regulations

Treasury Regulations are the Treasury Department's official interpretations of the IRC. They provide detailed guidance on how to comply with tax laws and are arranged in a similar structure to the IRC.

IRS Revenue Rulings

IRS Revenue Rulings are official interpretations by the IRS, providing taxpayers with guidance on how the IRS would apply the tax law to specific factual situations.

Court Decisions

Judicial authority includes decisions made by the Tax Court, District Courts, and other federal courts. These decisions interpret tax laws and can set precedents for future cases.
