The Internal Revenue Code is the most authoritative source of income tax law. In trying to resolve an income tax question, however, a tax researcher also consults administrative rulings (Income Tax Regulations, Revenue Rulings, etc.) and court decisions. Why wouldn't the tax researcher just consult the Code since it is the highest authority? Similarly, why is there a need for administrative rulings and court decisions?

A. The Code contains general language and does not address the many specific situations and transactions that occur. To resolve tax questions concerning specific situations, administrative rulings and court decisions are an integral part of the income tax law.

B.The Code does not include all tax laws. Administrative rulings and court decisions contain tax laws that are not included in the Code.

C.Administrative rulings and court decisions contain rulings that can override the Code and that provide greater tax savings.

D.Administrative rulings and court decisions contain tax laws that are inconsistent with the Code. Tax researchers can use administrative rulings and court decisions in place of the law stated in the Code when it is more beneficial.
