Federal Tax Authority, Guidance, and Legislative Change

This chapter covers the authority structure that underlies TCP analysis. The key is to understand where tax rules come from, how administrative and judicial sources interact, and why legislative change can alter both planning logic and exam emphasis.

In This Chapter

• Internal Revenue Code and Treasury Regulations explains the primary statutory and regulatory authority base.
• IRS Publications and Rulings covers the administrative guidance used in practice and exam analysis.
• Court Hierarchy and Tax Precedent shows how judicial authority shapes tax interpretation.
• Legislative Changes and Exam Impact explains how tax-law change affects planning and preparation.

How to Use This Chapter

• Read this chapter before deeper TCP planning work if tax authority still feels fragmented.
• Focus on which source is controlling, interpretive, or merely informative.
• Return here whenever a TCP question depends on authority hierarchy rather than calculation alone.
