Final answer:
The claim that IRS agents must give IRS Code greater weight than Treasury Regulations is false. Both are integral in tax law, with the Code providing legislative authority and the Regulations offering official interpretation.
Step-by-step explanation:
The statement that IRS agents must give the Code greater weight than Regulations when dealing with taxpayers and their representatives is false. The Internal Revenue Code (IRC), created by Congress, is the supreme source of tax law in the United States.
However, the Treasury Regulations, which are issued by the Treasury Department under the authority granted by Congress, provide the official interpretation of the IRC and are very important in understanding how the law is applied. In practice, both the Code and the Regulations are essential, and the Regulations can provide critical guidance that is given significant respect and weight in the application of the tax laws.
